Sistema de ahorro energético con recuperación de calor de secado con bomba de calor

Con el mayor desarrollo de la economía china, el uso de energías renovables se extenderá cada vez más. Los secadores deshumidificadores con bomba de calor y función de recuperación de calor de placas se han desarrollado rápidamente en los últimos años y se han utilizado ampliamente en la cuenca del río Yangtsé, en el suroeste y el sur de China.

La unidad, que utiliza el principio de cano inverso y combina una eficiente tecnología de recuperación de calor, durante todo el proceso de secado y deshumidificación, canaliza el aire húmedo de la cámara conectada al host a través del conducto mediante el colector de calor de la placa de calor sensible, recuperando el calor sensible y el calor latente del aire caliente y húmedo mediante reciclaje térmico. Esto mejora considerablemente el rendimiento del host, la velocidad de secado y la calidad del material. El calor residual no solo mejora el rendimiento de la unidad, sino que también reduce la contaminación térmica ambiental y alivia el efecto de isla de calor urbana.

El sistema de recuperación de calor de secado con bomba de calor no solo se utiliza en el secado de lodos, sino también en muchas otras industrias. Se caracteriza por su alta calidad de secado y un alto grado de automatización, lo que lo convierte en la mejor opción para el ahorro energético, la sostenibilidad y la protección del medio ambiente en la industria moderna del secado.

Principio de funcionamiento de las secadoras con bomba de calor con y sin recuperación de calor

Cuando el secador con bomba de calor seca el aire, este forma un ciclo cerrado entre la cámara de secado y el equipo. La función de absorción de calor del evaporador se utiliza para enfriar y deshumidificar el aire caliente y húmedo, y la función de liberación de calor del condensador se utiliza para calentar el aire frío y seco, logrando así el efecto de deshumidificación y secado cíclicos.

La principal diferencia entre los secadores con recuperación de calor y los secadores con bomba de calor sin ella radica en los diferentes modos de circulación del aire. El primero está equipado con un intercambiador de calor sensible de placas, que realiza las funciones de preenfriamiento y precalentamiento durante la circulación del aire, reduciendo la carga del compresor y logrando el objetivo de ahorro energético.

Análisis del ahorro energético de la recuperación de calor

Tomando como ejemplo una secadora con bomba de calor, la temperatura del aire de secado está diseñada para ser de 65 °C, la humedad relativa es de 30%, la temperatura del aire circulante es de 65 °C, la temperatura antes de pasar por el evaporador es de 65 °C y la temperatura después del enfriamiento por evaporación es de 35 °C. El condensador debe calentar el aire de 35 °C a 65 °C antes de poder usarse.

Tras la instalación del intercambiador de calor BXB500-400-3.5, el aire de retorno a 35 °C absorbe el calor del aire de escape tras pasar por el intercambiador de placas, lo que eleva la temperatura a 46,6 °C. El condensador solo necesita calentar el aire de 46,6 °C a 65 °C para cumplir con los requisitos de uso, lo que reduce considerablemente la carga del evaporador y el condensador, lo que reduce el consumo de energía de toda la máquina y permite el ahorro energético.

Un método rápido para eliminar el humo blanco

The principle of using a condenser for dehumidification to eliminate white smoke is mainly based on the physical changes of water vapor in the flue gas. The condenser cools the flue gas with low-temperature water or air, gradually reducing its temperature, and the water vapor inside begins to condense into small water droplets. These small water droplets gather inside the condenser and eventually form liquid water, which is then removed through drainage pipes. Dehumidification through a condenser is an effective technical means to eliminate white smoke. It can not only reduce visual pollution, but also help improve the operational efficiency and energy-saving effect of environmental protection equipment. We can provide you with a suitable dehumidification solution for flue gas, which is both economical and environmentally friendly. Welcome to consult us via email.

Efficient equipment for removing industrial flue gas

Industrial flue gas desulfurization equipment with heat exchange technology to reduce the water vapor content in flue gas, thereby eliminating the white smoke plume generated during chimney emissions. The following are several common methods for flue gas whitening:

Flue gas heating technology: The desulfurized wet flue gas is heat exchanged with industrial high-temperature flue gas through a heat exchanger to increase the emission temperature of the flue gas, thereby reducing the relative humidity of the flue gas and avoiding the condensation of water vapor to form white smoke. This method can effectively reduce the generation of white smoke, but it requires a certain amount of energy to heat the smoke.

Flue gas condensation technology: First, partially condense the water vapor in the saturated flue gas, and then heat the flue gas. This method reduces the formation of white smoke by lowering the moisture content in the flue gas, while also recovering some water resources.

MGGH technology: Install flue gas cooling heat exchangers before and after electrostatic precipitator, install flue gas heating heat exchangers after desulfurization, and set up a heat medium water circulation system. This technology extracts the heat from the original smoke to heat the clean smoke, which usually needs to be raised to 75-80 ℃ to avoid the production of white smoke.

In summary, these methods each have their own advantages and disadvantages, and are suitable for different industrial environments and needs. When selecting specific flue gas desulfurization technologies, factors such as process conditions, waste heat resources, and investment requirements need to be considered.

Depurador de humo: Eliminación eficiente del humo blanco con métodos físicos.

El depurador de humos condensa el vapor de agua de los gases de combustión en líquido mediante un condensador, y los contaminantes gaseosos se adhieren al líquido condensado antes de ser descargados a través de los gases de escape. Esta tecnología no requiere un colector, sino que se basa en el líquido precipitado para eliminar los contaminantes, lo que reduce los costos operativos y minimiza la contaminación ambiental causada por el humo blanco.

Los equipos de eliminación de humo blanco que fabricamos presentan un diseño compacto, una instalación flexible y un funcionamiento sencillo, lo que permite eliminar de forma eficiente y rápida el humo blanco generado en la producción industrial. Se utilizan principalmente para la desulfuración y el blanqueo de gases de combustión de calderas de carbón y gas, centrales eléctricas, metalurgia y otras industrias.

Energy saving devices for heat dissipation in computer rooms

The heat exchange core of the computer room's heat dissipation energy-saving device is an efficient heat dissipation solution specifically designed for data centers or server rooms. By optimizing heat exchange efficiency, energy consumption can be reduced and system performance can be improved. The heat exchanger produced by our company uses hydrophilic aluminum foil as the heat exchange material, and the surface has been specially treated to have excellent hydrophilicity, which can promote the rapid formation and removal of condensed water. During the heat exchange process, the hydrophilic layer can effectively increase the heat exchange area and improve the heat exchange efficiency. Adopting a multi-layer microchannel design increases the contact area between the fluid and the metal wall, thereby improving the heat transfer efficiency. Greatly improved the energy efficiency ratio of data centers and reduced operating costs.

Design of Drying, Dehumidification and Heat Recovery System

With the rapid development of manufacturing industry, many products require drying and dehumidification treatment during the production process. These processes not only require efficient moisture removal, but also require maintaining the characteristics and quality of the material. Traditional drying and dehumidification methods often consume high energy and may have adverse effects on the environment, such as emitting greenhouse gases and other pollutants.


By adopting efficient heat recovery technology, waste heat can be maximally recovered and reused to reduce energy consumption. Heat recovery technology has been widely applied in multiple industries to improve energy efficiency and reduce operating costs. But in the field of drying and dehumidification, the potential of this technology has not been fully tapped. We customize and develop a heat recovery system that suits your specific production needs and on-site conditions. We carefully design the system layout for you to ensure minimal loss of thermal energy during conversion and transmission. Welcome to inquire via email.

Heat recovery technology for air conditioning systems in shopping malls

In today's pursuit of high-quality shopping experience, we not only focus on the richness and diversity of products, but also care about the comfort and sustainability of the shopping environment.
The core of our company's air conditioning system heat recovery technology lies in the perfect combination of high-efficiency heat exchanger design and intelligent control system. It can efficiently collect the waste heat generated during the operation of air conditioning and convert it into valuable energy for winter heating, domestic hot water, and even pre cooling fresh air in shopping malls.
This process does not require additional energy consumption and can achieve internal energy recycling, significantly reducing the overall energy consumption cost of the mall. And it can automatically adjust the operating status and heat recovery intensity of the air conditioner. This means that whether it's scorching summer or cold winter, the mall can ensure constant temperature and humidity, providing customers with the most comfortable shopping environment while achieving the best energy-saving effect. Welcome to consult via email.

Energy saving scheme for heat recovery of central air conditioning system

In the operation of central air conditioning systems, we can adopt high-efficiency heat exchangers for energy-saving renovation plans, and can choose plate heat exchangers or microchannel heat exchangers with high heat transfer efficiency and low fluid resistance. Our heat exchanger has a larger heat transfer area and more efficient heat transfer performance, which can reduce energy consumption under the same heat transfer conditions. Install a waste heat recovery device in the central air conditioning system to recover and reuse the emitted heat. It can also be combined with heat pump technology, which is an efficient way of transferring heat energy by consuming a small amount of electricity or fuel energy to transfer the heat from a low-temperature heat source to a high-temperature heat source. The application of heat pump technology in central air conditioning systems can improve the coefficient of performance (COP) of the system and reduce energy consumption.

Free combination of heat exchangers for air conditioning units

Modular air conditioning units are an efficient and flexible central air conditioning solution that can be freely combined according to the actual needs of buildings, meeting different cooling or heating requirements by increasing or decreasing the number of units. Each unit is connected to each other through a return pipe and a supply pipe, forming a modular combination of a main return pipe and a main supply pipe.
We use plate heat exchangers, which have a heat transfer coefficient 3-5 times higher than tube heat exchangers under the same pressure loss. They occupy one-third of the space of tube heat exchangers and can achieve a heat recovery rate of over 90%.
Our air-cooled heat pump air conditioning unit adopts a compression refrigeration cycle, which is a dual-purpose air conditioning cooling and heating source unit. During summer cooling, outdoor air is used for heat dissipation (air cooling), while during winter heating, heat is extracted from outdoor air (air source).
