DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0017] The present application provides a high-temperature industrial waste gas treatment device, which is mainly used to solve the problem that most of the existing technologies use water spray cooling to cool the high-temperature waste gas, but cannot utilize the waste heat of the high-temperature waste gas, resulting in a waste of resources, and provides the following technical solutions, which will be described in detail below:

[0018] Embodiment 1:

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments, it includes a filtering mechanism 1, one end of the filtering mechanism 1 is connected to a heat exchange mechanism 2, the rear end of the heat exchange mechanism 2 is connected to a water supply mechanism 3, one end of the heat exchange mechanism 2 is connected to a spray tower 4, an air duct 5 is installed at the air outlet of the spray tower 4, one end of the air duct 5 is connected to a reverse fan 6; the air outlet of the reverse fan 6 is connected to an exhaust pipe 7.

[0020] Specifically: the high-temperature exhaust gas is rationally utilized to heat the cold water through the heat exchange mechanism 2. In order to improve the heating efficiency, a heat conduction and flow guide pipe 203 is installed in the annular water pipe 202 to make the heating more uniform. The heated water is connected to an external water pipe to provide hot water to the outside world. The water output of the cold and hot water sources is regulated by the three-way valve 306 and the temperature sensor 307.

[0021] The working principle here is: when the high-temperature exhaust gas generated during factory operations is treated, the reverse fan 6 is started, and the exhausted gas first enters the filter bin 101 through the high-temperature air inlet pipe 102, and the dust and other impurities in the gas are filtered through the internal glass fiber filter plate 103. The filtered high-temperature gas enters the heat exchanger shell 201 through the high-temperature air outlet pipe 104. At this time, the water pump 303 is started to let the cold water in the water tank 301 enter the water pipe 202 through the water supply pipe 302. The heat conduction guide plate 203 in the heat exchanger makes the water in the water pipe 22 heated evenly, thereby improving the heating efficiency. The obtained hot water is discharged from the water outlet pipe 304 to meet the water demand in life. The low-temperature gas obtained after heat exchange enters the spray tower 4 through the low-temperature air outlet pipe 204 for thorough cooling treatment, and is finally led out by the reverse fan 6 and discharged through the exhaust pipe 7.

[0022] like Figure 2 , Figure 3 As shown, in some embodiments, the filter mechanism 1 includes a filter chamber 101 with a glass fiber filter plate 103 installed inside, the air inlet of the filter chamber 101 is connected to a high-temperature air inlet pipe 102, and the air outlet is connected to a high-temperature air outlet pipe 104. The filter mechanism 1 is connected to the air inlet of the heat exchange mechanism 2 through the high-temperature air outlet pipe 104. The working principle here is: the high-temperature industrial waste gas is preliminarily treated by the filter mechanism 1. The pores of the glass fiber filter plate 103 are very small. Its use enhances the screening and diffusion effects of small dust particles, so it has a very high filtration efficiency. When the treated high-temperature gas enters the heat exchange mechanism 2 again, the risk of clogging the heat conduction guide plate 203 due to the adsorption of dust in the gas will be reduced.

[0023] Embodiment 2:

[0024] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0025] like Figure 3As shown, in some embodiments, the heat exchange mechanism 2 includes a heat exchanger shell 201, a heat conduction guide tube 203 is installed in the heat exchanger shell 201, a water pipe 202 is wrapped around the outside of the heat conduction guide tube 203, both ends of the water pipe 202 pass through the heat exchanger shell 201 and are connected to the water supply mechanism 3, a low-temperature outlet pipe 204 is installed at the air outlet of the heat exchanger shell 201, and one end of the low-temperature outlet pipe 204 is connected to the air inlet of the spray tower 4. The working principle here is: the filtered high-temperature gas enters the heat exchanger shell 201 through the high-temperature outlet pipe 104, at this time, the water pump 303 is started to drive the cold water in the water tank 301 into the water pipe 202 through the water supply pipe 302, the heat conduction guide plate 203 in the heat exchanger makes the water in the water pipe 22 heated evenly, thereby improving the heating efficiency, and the low-temperature gas obtained after heat exchange enters the spray tower 4 through the low-temperature outlet pipe 204 for thorough cooling treatment.

[0026] like Figure 1 , Figure 2 As shown, in some embodiments, the water supply mechanism 3 includes a water tank 301, a water supply pipe 302, a water outlet pipe 304, a connecting pipe 305, etc. The water outlet of the water tank 301 is connected to the water inlet of the water pipe 202 through the water supply pipe 302, a water pump 303 is installed between the water supply pipe 302 and the water tank 301, one end of the water outlet pipe 304 is connected to the water outlet of the water pipe 202, the water supply pipe 302 and the water outlet pipe 304 are interconnected through the connecting pipe 305, a three-way valve 306 is installed between the water outlet pipe 304 and the connecting pipe 305, and a temperature sensor 307 is installed on the water outlet pipe 304. The working principle here is: the cold water in the water tank 301 is transported by the water pump 303, the cold water flows through the water pipe 202 and is heated by high-temperature gas and then discharged from the water outlet pipe 304 to meet the water demand in life, the temperature sensor 307 is used to detect the water temperature of the drain outlet, if the water temperature needs to be adjusted, the three-way valve 306 can be controlled to achieve it.
