Description

technical field [0001] The present invention relates to a device for treating waste hot gas, and more particularly to a waste heat treatment device for recovering and reusing waste heat for various purposes, such as providing hot water and improving the purification efficiency of pollutants in the gas. Background technique [0002] Figure 4 It is a process flow diagram of traditional waste heat treatment equipment, wherein a treatment chamber 100 includes an inlet 101 and an outlet 102, and process materials are heated and treated in the treatment chamber 100 . The exhaust pipe 111a is arranged on the upper part of the processing chamber 100, and the high-temperature exhaust gas is absorbed from the processing chamber 100 by the operation of the blower 104, and the exhaust pipe 111a is connected with the exhaust gas treatment device 110 to collect the exhaust gas, thereby separating the pollutants in the exhaust gas. [0003] The exhaust gas treatment device 110 includes a ...

Problems solved by technology

[0006] However, according to Figure 5 In the conventional device shown, due to the temperature difference between the high-temperature gas in the processing chamber 100 and the external low-temperature gas, the air in the inlet 101 and the outlet 102 of the processing chamber 100 is condensed, and the contact of the condensed water with the process material cause poor treatment

[0007] The conventional technology has a disadvantage that it takes a lot of time to preheat the material for the production process, causing inconvenience, poor efficiency and low productivity

[0008] Because the energy consumed by preheating causes the production cost to increase, and the waste heat cannot be reused, so the traditional technology is uneconomical and saves
