Problems solved by technology

It only increases the contact area between water and exhaust gas through the bent coiled tube, so as to achieve high efficiency of waste heat recovery and utilization, but it still has the following shortcomings: First, due to the continuous flow of water in the coiled tube, its contact time with hot air is limited , there are requirements for the speed of water flow and the flow speed of hot exhaust gas. When the speeds of the two do not match, it will cause waste of heat energy of exhaust gas or waste of water resources, and it is impossible to realize effective recovery of waste heat of exhaust gas; secondly, it only The area in contact with the exhaust gas is increased through the curved coiled tube. This method is still relatively passive to absorb the waste heat of the exhaust gas, and the ability to absorb the waste heat of the exhaust gas is limited; finally, when heating, only the water in contact with the inner wall of the coiled tube can be heated, and the inner center of the coiled tube The water in the area is heated slowly, and the heat cannot be evenly distributed in the water, which affects the efficiency of absorbing waste heat from exhaust gas

Abstract

An environment-friendly waste heat recovery device for waste gas treatment, comprising a shell structure (1) and a closed structure (2) arranged on the shell structure (1), the environment-friendly waste heat recovery device for waste gas treatment also includes a housing The liquid collection structure (4) in the housing structure (1), the gas collection structure (5) arranged around the liquid collection structure (4), the liquid collection structure (4) includes a heat conducting frame (41 ), a number of first springs (42) housed in the heat conduction frame (41), a stirring frame (43), a heat conduction plate (44) located below the heat conduction frame (41), a heat conduction plate (44) located under the heat conduction frame (41 ) a positioning rod (45) on one side, a positioning frame (46), a second hose (47) located on the other side of the heat conducting frame (41), several sealing frames accommodated in the heat conducting frame (41) (48). The invention can effectively evenly distribute the heat in the heat conduction frame in the water, and is beneficial to ensure the heat absorption efficiency of the water in the heat conduction frame in contact with the inner wall.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an environment-friendly waste heat recovery device for waste gas treatment. Background technique [0002] In the chemical industry and other fields, a large amount of high-temperature exhaust gas will be generated. These exhaust gases are high in temperature and are generally discharged directly, which will not only cause environmental pollution, but also cause waste of energy, which is not economical and environmentally friendly. [0003] Chinese patent CN104121789A discloses an energy-saving waste gas waste heat recovery system, including: a waste gas channel and a water flow channel. Inside, the water flow channel is a continuously bent serpentine pipe, the two ends of the water flow channel are water inlet and water outlet respectively, and the water inlet and water outlet run through the pipe wall of the waste gas channel. It only increases the contact area between wate...
