The kiln waste heat recovery and reuse system aims to fully utilize the high-temperature heat in the kiln exhaust gas, and achieve a win-win situation of energy conservation and environmental protection through gas stainless steel cross flow heat exchangers. The core of this solution lies in the use of a stainless steel cross flow heat exchanger, which efficiently exchanges heat between high-temperature exhaust gas and cold air, generating hot air that can be reused.

Working principle: The exhaust gas and cold air flow in a cross flow manner inside the heat exchanger and transfer heat through the stainless steel plate wall. After releasing heat from exhaust gas, it is discharged. Cold air absorbs the heat and heats up into hot air, which is suitable for scenarios such as assisting combustion, preheating materials, or heating.

장점:

Efficient heat transfer: The cross flow design ensures a heat transfer efficiency of 60% -80%.
Strong durability: Stainless steel material is resistant to high temperatures and corrosion, and can adapt to complex exhaust environments.
Flexible application: Hot air can be directly fed back to the kiln or used for other processes, with significant energy savings.
System process: Kiln exhaust gas → Pre treatment (such as dust removal) → Stainless steel heat exchanger → Hot air output → Secondary utilization.

This solution is simple and reliable, with a short investment return cycle, making it an ideal choice for kiln waste heat recovery, helping enterprises reduce energy consumption and improve efficiency.

Application of Cross Flow Heat Exchanger in Indirect Evaporative Cooling System of Data Center

데이터센터 간접 증발 냉각 시스템에 교차흐름 열교환기 적용

The application of cross flow heat exchangers in Indirect Evaporative Cooling (IDEC) systems in data centers is mainly reflected in efficient heat exchange, reducing energy consumption, and improving data center cooling efficiency. Here are its key roles and advantages:

Basic working principle
Cross flow heat exchanger is a type of heat exchange device whose structure allows two streams of air to cross each other while maintaining physical isolation. In indirect evaporative cooling systems in data centers, it is typically used for heat exchange between cooling air and outdoor ambient air without direct mixing.
The workflow is as follows:
The primary air (data center return air) exchanges heat with the secondary air (external ambient air) through one side of the heat exchanger.
The secondary air evaporates and cools in the humidification section, reducing its own temperature, and then absorbs heat in the heat exchanger to cool the primary air.
After the primary air is cooled down, it is sent back to the data center to cool down the IT equipment.
The secondary air is ultimately discharged outdoors without entering the interior of the data center, thus avoiding the risk of pollution.

Advantages in Data Centers
(1) Efficient and energy-saving, reducing cooling demand
Reduce cooling load: By using cross flow heat exchangers, data centers can utilize external air cooling instead of relying on traditional mechanical refrigeration (such as compressors).
Improve PUE (Power Usage Effectiveness): Reduce the operating time of mechanical cooling equipment, lower energy consumption, and make PUE values closer to the ideal state (below 1.2).
(2) Completely physically isolated to avoid contamination
Cross flow heat exchangers can ensure that outdoor air does not come into direct contact with the air inside the data center, avoiding pollution, dust, or humidity affecting IT equipment. They are suitable for data centers with high air quality requirements.
(3) Suitable for various climatic conditions
In dry or warm climates, indirect evaporative cooling systems are particularly effective and can significantly reduce the cooling costs of data centers.
Even in areas with high humidity, optimizing the design of heat exchangers can improve heat exchange efficiency.
(4) Reduce water resource consumption
Compared to direct evaporative cooling (DEC), indirect evaporative cooling does not require direct spraying of water into the air of the data center, but rather indirect cooling through a heat exchanger, thus reducing water loss.

Applicable scenarios
Cross flow heat exchangers are widely used in the following types of data centers:
Hyperscale Data Center: Requires efficient and energy-saving cooling solutions to reduce operating costs.
Cloud computing data center: requires high PUE values and seeks more sustainable cooling methods.
Edge Data Center: typically located in harsh environments, requiring efficient and low maintenance cooling systems.

Challenge and Optimization Plan
Heat exchanger size and efficiency: Larger cross flow heat exchangers can improve heat exchange efficiency, but they also increase the footprint, so optimization design is needed, such as using aluminum or composite material heat exchangers to improve heat exchange efficiency.
Scaling and maintenance: Due to humidity changes, heat exchangers may experience scaling issues, requiring regular cleaning and the use of corrosion-resistant coatings to extend their lifespan.
Control system optimization: Combined with intelligent control, dynamically adjust the working mode of the heat exchanger based on external environmental temperature, humidity, and data center load conditions to improve system adaptability.

Future Development Trends
New efficient heat exchange materials, such as nano coated heat exchangers, further improve heat exchange efficiency.
Combined with AI intelligent control system, dynamically adjust the heat exchange according to the real-time load of the data center.
Combining liquid cooling technology to further improve heat dissipation efficiency in high-density server rooms.

Cross flow heat exchangers play an important role in the indirect evaporative cooling system of data centers, providing efficient heat transfer, reducing energy consumption, minimizing pollution, and improving equipment reliability. They are currently one of the important technologies in the field of data center cooling, especially suitable for large-scale, high-efficiency data centers.

상업용 환기 및 에너지 회수

적절한 실내 공기 질(IAQ)은 지역 상황과 기후에 따라 여러 요인에 따라 달라집니다. 먼지, 꽃가루 또는 기타 오염 물질이 포함된 공기로 인해 호흡기 문제와 같은 건강 문제가 발생할 수 있습니다. 열악한 실내 환경은 건물을 손상시킬 수도 있습니다.

상업용(비주거용) 공기 조절 장치는 사무실, 호텔, 공항과 같은 건물에 맞게 설계된 대형 장치인 경향이 있습니다. 과제는 가능한 한 적은 에너지 입력으로 편안한 IAQ를 달성하는 것입니다. 즉, 압력 강하가 낮아야 하고(팬 전력이 덜 필요함) 열/습도 효율이 높아야 합니다(난방/냉방/습도 제어에 소비되는 에너지가 적음).

지리적 지역에 따라 열교환기의 주요 목적은 건물에 유입되기 전에 외부 공기를 가열하거나 냉각(그리고 제습도 가능)하는 것입니다.

공기 처리 장치(AHU)는 환기 시스템의 중심에 있습니다. 최소한 AHU에는 각 공기 채널에 하나 이상의 팬이 포함되어 있어 장치를 통해 공기를 이동합니다. 양쪽에 있는 필터는 먼지, 꽃가루 등을 제거하고 팬을 보호합니다. 마지막으로 열교환기는 배출 공기에서 필요한 열이나 습도를 공급 공기로 전달합니다.

공기 대 공기 열교환기를 구현하는 것은 일반적으로 폐열로 간주되는 것을 활용하는 훌륭한 방법입니다. 공기 대 공기 열교환기는 공급 공기와 배기 공기 사이의 온도 차이를 이용하여 시스템의 효율성을 높입니다. 공기 대 공기 열교환기에는 회전식 열교환기와 판형 열교환기라는 두 가지 유형이 있습니다.

유형과 정확한 구성은 응용 분야에 따라 달라집니다. 두 유형 모두 알루미늄으로 제작되어 효율적인 열 전달 성능과 매우 긴 수명과 같은 뛰어난 특성을 가지고 있습니다. 각 제품에 대해 다양한 설계 변수와 옵션을 제공하여 모든 AHU에 완벽하게 맞고 성능이 발휘되도록 합니다.

데이터 센터의 간접 냉각

Modern data centers are remarkably technologically complex, and keeping them running safely and efficiently requires continual close monitoring and management.

Maintaining the correct temperature is among the most important tasks faced by data center managers. Should the temperature and humidity rise to excessive levels inside the data center, condensation can start forming, damaging the machines within. This can cause massive damage and disruption, so it must be avoided at all costs. Fortunately, various technologies are on hand that can help keep data center temperatures at the right level.

There are numerous ways to cool a data center. Indirect air cooling uses external air, but by including an air-to-air heat exchanger, the outside air is kept in a separate loop, providing cooling without entering the server room.

Indirect cooling methods benefit by not contaminating the inside air with outdoor air pollutants and humidity. A heat exchanger keeps both airstreams separated while transferring the heat from the inside to the outside of the data center building. Consequently, the ambient and indoor air never mix.

Dry cooling is usually sufficient if the data center is located in a consistently low-temperature area, meaning no water is involved. However, by spraying water on the ambient air side of the heat exchanger, an evaporative effect is achieved, resulting in a lower indoor air temperature. This method is called indirect evaporative cooling (IEC).

Ideally suited for warm, dry climates, IEC provides excellent cooling potential with low operational- and first-cost. Ambient temperature reductions of 6-8 °C (10-15 °F) are typical in summer conditions. IEC provides up to 28% in energy savings compared to conventional free cooling and 52% to air-cooled Free Cooling alternatives.

Evaporative cooling requires a plate heat exchanger that balances high efficiency with low pressure drop, offers solid corrosion protection, and reliable water tightness. Cross-flow heat exchangers meet all these requirements while providing outstanding cooling capacity.

Our crossflow heat exchangers, especially with evaporative cooling technology, provide an efficient, low-cost, and environmentally friendly alternative to traditional cooling methods.

A rapid method for eliminating white smoke

흰 연기를 제거하는 빠른 방법

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.

배가스 가열 기술: 탈황된 습식 배가스는 열교환기를 통해 산업용 고온 배가스와 열교환되어 배가스의 배출 온도를 높입니다. 이를 통해 배가스의 상대 습도를 낮추고 수증기가 응축되어 백연이 생성되는 것을 방지합니다. 이 방법은 백연 발생을 효과적으로 줄일 수 있지만, 연기를 가열하는 데 일정량의 에너지가 필요합니다.

연도가스 응축 기술: 먼저 포화된 연도가스 내의 수증기를 부분적으로 응축시킨 후 연도가스를 가열합니다. 이 방법은 연도가스 내 수분 함량을 낮춰 백연 발생을 줄이는 동시에 일부 수자원을 회수합니다.

MGGH 기술: 전기집진기 전후에 배가스 냉각 열교환기를 설치하고, 탈황 후 배가스 가열 열교환기를 설치하며, 열매체 순환 시스템을 구축합니다. 이 기술은 원연의 열을 추출하여 청정 연기를 가열하는데, 일반적으로 백연 발생을 방지하기 위해 75~80℃까지 가열해야 합니다.

요약하자면, 이러한 방법들은 각각 장단점을 가지고 있으며, 다양한 산업 환경과 요구에 적합합니다. 특정 연도가스 탈황 기술을 선택할 때는 공정 조건, 폐열 자원, 투자 요건 등의 요소를 고려해야 합니다. 이메일로 문의해 주세요.
