How does a counterflow heat exchanger work?

In the counterflow heat exchanger, two neighboring aluminum plates create channels for the air to pass through. The supply air passes on one side of the plate and the exhaust air on the other. Airflows are passed by each other along parallel aluminum plates instead of perpendicular like in a crossflow heat exchanger. The heat in the exhaust air is transferred through the plate from the warmer air to the colder air.

Sometimes, the exhaust air is contaminated with humidity and pollutants, but airflows never mix with a plate heat exchanger, leaving the supply air fresh and clean.

Vegetable, tea, bean drying room, dehumidification and moisture removal air heat exchanger

Efficient dehumidification and dehumidification systems are required during the drying process of agricultural products such as vegetables, tea, and beans to ensure the quality and efficiency of the drying process. The gas heat exchanger plays a crucial role in this process. The following is a detailed introduction to the dehumidification and dehumidification system of vegetable, tea, and bean drying rooms.

Dehumidification process:
The humid and hot air in the drying room is drawn out by the exhaust fan and exchanges heat with the incoming dry air when passing through the air air heat exchanger.
After passing through the heat exchanger, the temperature of the discharged humid and hot air decreases, and the water vapor condenses into liquid water and is discharged.
The incoming dry air is preheated by a heat exchanger and enters the drying room, improving the drying efficiency.

Application scenarios
Vegetable drying: such as chili peppers, carrots, cabbage, etc., by controlling temperature and humidity, the color and nutrition of the dried vegetables are not destroyed.
Tea drying: For green tea, black tea, oolong tea, etc., the aroma and quality of the tea are maintained through appropriate temperature and humidity control.
Legumes drying: such as soybeans, mung beans, red beans, etc., are dried evenly with hot air to ensure the dryness and storage quality of the beans.

The application of gas air heat exchangers in vegetable, tea, and bean drying rooms has improved the energy efficiency and product quality of the drying process through efficient dehumidification and dehumidification functions. Reasonable design and use can significantly reduce energy consumption and operating costs, while being environmentally friendly, making it an indispensable part of modern drying technology.

High temperature welded stainless steel plate heat exchanger

High temperature welded stainless steel plate heat exchanger is an efficient heat exchange device that achieves heat exchange between fluids by stacking multiple thin stainless steel plates to form countless microchannels. This type of heat exchanger has the advantages of compact structure, high heat transfer efficiency, high temperature resistance, corrosion resistance, etc., and is particularly suitable for gas waste heat recovery under high temperature conditions. High temperature gas enters one side of the heat exchanger, while low temperature gas enters the other side. Two types of gases exchange heat in the channels of thin stainless steel plates, and high-temperature gases transfer heat to low-temperature gases, achieving waste heat recovery. Widely used in industrial furnaces, metallurgical industries, chemical industries, incinerators, and other places. Plate heat exchangers have significant advantages in gas waste heat recovery, which can effectively improve energy utilization efficiency and reduce production costs. When selecting and using this type of heat exchanger, factors such as the characteristics of high-temperature gases and process requirements should be comprehensively considered, and appropriate models and materials should be selected.

Using bxb plate heat exchanger for flue gas whitening and de whitening

The flue gas of steel, coking, chemical industry and boiler is mostly sprayed or wet desulfurized before discharge, and the temperature drops to 45~80 ℃. At this time, the flue gas is saturated wet flue gas, and the flue gas contains a large amount of water vapor, which contains ablative salt, sulfur trioxide, gel dust, micro dust, etc. (all important components of haze).
Smoke whitening refers to the removal of some moisture from the smoke before it is discharged into the atmosphere, in order to prevent the chimney from emitting white smoke and reduce its impact on the environment. Normally, smoke whitening involves first cooling and condensing the smoke, followed by heating it. The main component of the air flue gas whitening unit is the BXB plate heat exchanger. In the plate heat exchanger, ambient air is used to cool the flue gas, thereby precipitating water from the flue gas. Afterwards, the flue gas is reheated to increase its temperature, so that there will be no "white smoke" when the flue gas is discharged into the atmospheric environment.

Drying waste heat recovery

The heat pump drying heat recovery system can be applied to the drying of food, medicinal materials, tobacco, wood, and sludge. It has the characteristics of good drying quality and high degree of automation, and is the best and preferred product for energy-saving, green, and environmental protection in the modern drying industry.

The unit utilizes the reverse Carnot principle and efficient heat recovery technology. Throughout the entire drying and dehumidification process, the humid air in the drying room is connected to the main unit through a return air duct. The sensible and latent heat of the humid air is recovered using a sensible heat plate heat recovery device for heat recovery and reuse, greatly improving the performance of the main unit, drying speed, and material quality.

Stainless steel plate heat exchanger for organic waste gas combustion furnace

Regenerative Thermal Oxidizer (RTO) is a device for treating organic waste gases (VOCs), which oxidize organic matter into harmless carbon dioxide and water through high-temperature combustion. During this process, a large amount of high-temperature flue gas is generated, and if the thermal energy of these flue gases is not recycled, it will cause great energy waste. Stainless steel plate heat exchangers are key equipment for improving the overall efficiency of RTO systems for waste heat recovery.
Stainless steel plate heat exchangers utilize the heat energy of high-temperature exhaust gas to transfer heat to cold fluids (usually fresh air or process water) through heat transfer plates. High temperature exhaust gas is discharged from RTO and enters one side of the plate heat exchanger. When the exhaust gas flows through the heat exchanger, heat is transferred to the cold fluid on the other side through a stainless steel heat transfer plate. The cold fluid is heated in the heat exchanger and absorbs the heat from the exhaust gas. After being cooled, the exhaust gas is discharged, and the heat energy is recovered for preheating fresh air or other process flows.
Heat transfer plates are usually designed as corrugated or other complex structures to increase heat transfer area and efficiency. The material used is 304 or 316 stainless steel, which has excellent corrosion resistance and high strength,
The utilization of stainless steel plate heat exchangers greatly reduces energy consumption and greenhouse gas emissions. Plate heat exchangers have a compact structure, which is smaller in footprint and easier to install compared to traditional shell and tube heat exchangers.
Stainless steel plate heat exchangers are widely used in industries such as petrochemicals, coatings, pharmaceuticals, and food processing
The stainless steel plate heat exchanger plays a crucial role in the waste heat recovery system of RTO organic waste gas combustion furnace, which can effectively improve the energy utilization efficiency of the system, reduce operating costs, and meet environmental requirements. Choosing the appropriate heat exchanger structure and material based on the specific application environment and requirements can maximize its advantages and ensure the long-term stable operation of the system.
