Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a heat and mass exchanger for waste gas treatment. Background Technique

[0002] In some industries, high-temperature treatment processes are often required, and a large amount of high-temperature waste gas will be generated during the high-temperature treatment process. If the high-temperature waste gas is directly discharged, it will not only damage the equipment, bringing greater potential safety hazards, but also cause serious pollution to the external environment. Therefore, the high-temperature waste gas needs to be treated before being discharged.

[0003] After retrieval, a heat exchanger for heat energy recovery and utilization of hot waste gas disclosed in Chinese Patent Application No. 202021430116.6 includes a heat exchanger housing and a cold air delivery pipe, and the cold air delivery pipe is evenly arranged in a coil in the heat exchanger housing; heat waste gas inlets and waste gas outlets are correspondingly opened at both ends of the heat exchanger housing, and both the heat waste gas inlets and the waste gas outlets communicate with the inside of the heat exchanger housing. A clean cold air inlet, a clean air outlet and a sewage outlet are opened at the bottom of the heat exchanger housing, and both ends of the cold air delivery pipe are respectively communicated with the clean cold air inlet and the clean air outlet. The patent has a simple structure, reasonable design, convenient operation, and is easy to clean, can efficiently recover and utilize the heat energy of the hot waste gas, is energy-saving and environmentally friendly, and has good market application prospects.

[0004] Although the patent has a simple structure, reasonable design, convenient operation, and is easy to clean, and can efficiently recover and utilize the heat energy of the hot waste gas, in actual use, the hot waste gas needs to come into contact with the cold air delivery pipe to achieve the effect of heat conduction. This process makes the impurities in the waste gas easily adhere to the surface of the cold air delivery pipe. Therefore, it is necessary for the staff to clean it regularly to ensure the efficiency of heat conduction. At the same time, the heat exchanger housing in this patent lacks corresponding heat insulation and thermal insulation structures, which leads to the heat of the hot waste gas being easily conducted to the surface of the heat exchanger housing, not only easily causing heat loss, but also easily scalding the staff, resulting in potential safety hazards.

[0005] Therefore, it is necessary to transform the heat exchanger in the above patent to effectively prevent the hot waste gas from coming into contact with the cold air delivery pipe to achieve the effect of heat conduction, which leads to the need for regular cleaning, and the lack of corresponding heat insulation and thermal insulation structures in the housing, resulting in easy heat loss and easy scalding of the staff.
