[0002] Waste gas treatment equipment is used to collect, treat, and purify harmful gases generated by industrial production, transportation, and other sources. Its primary purpose is to reduce environmental pollution and protect human health. There are many different types and technologies of waste gas treatment equipment. Depending on the type of waste gas being treated and the treatment requirements, these equipment can be categorized as follows: adsorption equipment, scrubbers, combustion equipment, catalytic converters, electrostatic precipitation equipment, and biofiltration equipment. Combustion equipment, among other things, burns harmful components in waste gas at high temperatures, converting them into harmless gases (such as carbon dioxide and water vapor). These are commonly used for the treatment of volatile organic compounds (VOCs).

[0011] Preferably, the tower wall of the waste gas combustion tower is made of a metal material with high heat transfer efficiency, and the water tank is made of a material with good thermal insulation effect.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model discloses a waste gas treatment equipment with waste heat recovery, wherein the outer wall of the waste gas combustion tower is provided with a jacket water chamber which can intelligently wait for the water inside to heat up to a certain temperature before replacing the water with new water and continuing to utilize the waste heat.

The jacketed water chamber 4 provided on the outer wall of the exhaust gas combustion tower 1 of the exhaust gas treatment equipment with waste heat recovery disclosed by the utility model can intelligently wait for the water inside to heat up to a certain temperature before replacing it with new water and continuing to utilize the waste heat. When the water temperature in the water tank 12 is not enough, the water in the water tank 12 is pumped into the jacketed water chamber 4 for continuous heating to maintain the temperature of the water in the water tank 12.

[0020] Furthermore, the waste gas combustion tower 1 and the water tank 12 are in contact with each other at the bottom and connected with a bracket 14 and are both installed on the top of the bracket 14, which is convenient for installation; further, the air inlet at the top of the waste gas combustion tower 1 is connected to the air outlet of the waste gas emission component through the waste gas pipe 2 and the first valve 3, which is convenient for supplying waste gas and burning and purifying the waste gas; further, the upper part of the waste gas combustion tower 1 is connected to the natural gas supply component through the natural gas pipe 5 and the second valve 6, which is convenient for supplying natural gas; further, an electronic lighter 7 is installed in the middle of the waste gas combustion tower 1 for easy ignition; further, a drain valve 15 is installed at the lower part of the water tank 12 for easy release of hot water for use; further, the tower wall of the waste gas combustion tower 1 is made of metal material with high heat transfer efficiency, and the water tank 12 is made of material with good thermal insulation effect, which is convenient for using waste heat to heat water.
