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.

Combustion furnace waste heat recovery, temperature resistance 450 ℃, pressure resistance 10000pa gas plate heat exchanger

The high-temperature and high-pressure gas plate heat exchanger in the waste heat recovery system of the combustion furnace is a specially designed equipment for recovering heat energy from high-temperature exhaust gas. This type of heat exchanger needs to operate stably in a high temperature of 450 ℃ and a high pressure environment of 10000Pa, and is suitable for various industrial applications such as petrochemical, steel, and power generation industries. The following is a detailed description of its working principle, main components, advantages, and applicable scenarios.

operational principle
The gas plate heat exchanger utilizes the heat of high-temperature exhaust gas to transfer heat to the cold air through stainless steel heat transfer plates, thereby preheating the cold air and improving the energy efficiency of the system. The specific process is as follows:

High temperature exhaust gas inflow: High temperature exhaust gas enters the heat exchanger through the inlet.
Heat transfer: High temperature exhaust gas flows through a stainless steel heat transfer plate, and heat is transferred to the cold air on the other side through the plate.
Cold air heating: Cold air is heated by the heat transfer plate through the other channel of the heat exchanger.
Cooling exhaust gas discharge: The cooled exhaust gas is discharged from the heat exchanger, and the heat energy is recovered.
advantage
Efficient heat transfer: Materials with corrugated structure design and high thermal conductivity ensure efficient heat exchange.
High temperature and high pressure resistance: able to operate stably under high temperature of 450 ℃ and high pressure of 10000Pa.
Corrosion resistance: Stainless steel material provides excellent corrosion resistance and is suitable for various industrial exhaust gas components.
Energy conservation and environmental protection: effectively recover waste heat, reduce energy consumption and greenhouse gas emissions.

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.
