[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Based on the existing existing technology that directly heats the air by means of electric heating, etc., which requires a lot of energy consumption and increases the production cost, this embodiment provides a catalytic combustion furnace intake air cooling device, please refer to Figures 1-4 The embodiment provides an air intake cooling device for a catalytic combustion furnace, which can save energy and improve resource utilization. The air intake cooling device for a catalytic combustion furnace includes an air condenser 2 mounted on a combustion furnace body 1. A heating device 3 for preheating the air and a refrigeration device 4 for cooling the air are respectively provided on the upper and lower sides of the air condenser 2. When the combustion furnace body 1 is started and operated, the air is preheated by the heating device 3 on the top of the air condenser 2, thereby reducing the electric heating time in the initial operation of the catalytic combustion furnace and saving electricity. In hot summer weather, air is taken in through a small air valve to clean the catalyst layer. The temperature of the catalyst layer does not drop significantly. At this time, the air is cooled by the refrigeration device 4 at the bottom of the air condenser 2, thereby reducing the temperature of the air used to clean the catalyst layer and ensuring the normal operation of the combustion furnace body 1 in hot seasons.

[0025] Since the prior art heats the air directly by means of electric heating or the like, which requires more energy consumption and increases the production cost, the device is further provided with a heating device 3, which includes an air outlet pipe 301 installed on the right side of the air condenser 2 and communicated with the combustion furnace body 1, a heating box 302 is installed on the outside of the air outlet pipe 301, a hot water tank 303 is installed on the top of the combustion furnace body 1, a connecting pipe 304 is installed between the heating box 302 and the hot water tank 303, a water inlet pipe 305 is installed on the left side of the hot water tank 303, and the water inlet pipe 305 is installed on the left side of the hot water tank 303. A valve 306 is installed on the outer surface of the heating box 302, and a drain pipe 307 is installed at the bottom of the heating box 302. When the combustion furnace body 1 is started, the valve 306 on the water inlet pipe 305 on the left side of the hot water tank 303 is opened, and the steam condensate of the drying room air heater is introduced into the hot water tank 303 through the water inlet pipe 305. The hot water flows into the interior of the heating box 302 through the connecting pipe 304, and heats the air inside the outlet pipe 301 wrapped therein, thereby making full use of steam preheating, reducing the electric heating time in the initial operation of the catalytic combustion furnace, and saving electricity.

[0026] In hot summer weather, the temperature inside the combustion furnace body 1 will rise. At this time, it is necessary to use a small air valve to clean the catalyst layer. However, the catalyst layer temperature does not drop significantly when the air at room temperature is blown. Therefore, the device is also provided with a refrigeration device 4. The refrigeration device 4 includes an air inlet pipe 401 installed on the left side of the air condenser 2, and a cooling box 402 is installed on the outside. A cold water tank 403 is installed at the bottom of the air condenser 2, and a water pump 404 is installed on the left side. The water outlet of the water pump 404 is installed. A water supply pipe 405 is installed, the top of which is connected to the cooling box 402. A return pipe 406 is installed on the front of the cooling box 402, and the bottom of which extends into the interior of the cold water tank 403. The water pump 404 is started to transport the cold water inside the cold water tank 403 to the interior of the cooling box 402 through the water supply pipe 405, thereby cooling the air inside the air intake pipe 401, and the cold water after heat exchange and cooling flows back into the interior of the cold water tank 403 through the return pipe 406, realizing the recycling of water resources.

[0027] A temperature sensor 308 is also installed on the inner wall of the cold water tank 403, and a refrigerator 407 is installed on the right side of the cold water tank 403. The refrigerator 407 is electrically connected to the temperature sensor 308. The temperature sensor 308 is used to monitor the water flowing back into the cold water tank 403 in real time. When the temperature does not achieve the cooling effect, the refrigerator 407 is started to cool the water inside the cold water tank 403 to ensure the cooling effect on the air.

[0028] Baffles 5 are installed in the hot water tank 303 and the cold water tank 403 at random. The interior of the air condenser 2 is composed of multiple stainless steel finned tubes. The setting of the baffles 5 can increase the turbulence of the water flow, thereby improving the heat transfer coefficient.

[0029] Example 2

[0030] On the basis of Example 1, Figures 1-4 As shown, when the air is heated by the hot water inside the cooling box 402, the hot water is generally continuously transported for heating and discharged, but this will cause a waste of water resources to a certain extent. Therefore, the device is equipped with a temperature sensor 308 on the top wall of the heating box 302, and an electric sealing valve 309 is installed on the connecting pipe 304 and the drain pipe 307. The electric sealing valve 309 is electrically connected to the temperature sensor 308. When the air inside the outlet pipe 301 is heated, the electric sealing valve 309 on the drain pipe 307 is in a sealed state until the temperature sensor 308 inside the heating box 302 detects that the water temperature inside the heating box 302 has dropped, and then sends an electrical signal to control the electric sealing valve 309 on the drain pipe 307 to open, discharge the cooled hot water, and transport new hot water through the connecting pipe 304, thereby improving the utilization rate of hot water resources and saving water resources.
