[0002] Formaldehyde is a colorless gas that is not easily detected at low concentrations and can be easily masked by other odors, such as air fresheners. At higher concentrations, it has a strong irritating and suffocating odor that irritates the eyes and nose. Formaldehyde is currently a toxic gas that seriously endangers human health and is more likely to appear in furniture and decoration materials that do not meet quality standards.

[0003] At present, when the three-way filter for formaldehyde production is in use, since the temperature of the mixed gas discharged during formaldehyde production is relatively high, the inside of the three-way catalytic converter will also be in a high temperature state when filtering the mixed gas. If the three-way catalytic converter is in a high temperature state for a long time, the service life of the three-way catalytic converter will be easily reduced, and the surface of the three-way catalytic converter will be easily broken, which will affect the filtering effect.

The vertical pipe 402 is fixedly arranged at the top of the fan 401, and the top of the vertical pipe 402 is connected to the left outer wall of the outer shell 1.

The horizontal pipe 404 is fixedly arranged at the top inner end of the outer shell 1, and the left side of the horizontal pipe 404 is connected to the top of the vertical pipe 402. The exhaust pipe 405 is fixedly arranged at the bottom end of the horizontal pipe 404.

A through hole is opened on the left side of the vertical pipe 402, and a through hole is opened on the right side of the top of the vertical pipe 402.

[0019] More specifically, the cooling mechanism 5 includes: a water chiller 501, a water pipe 502, a cooling pipe 503 and a hose 504;

[0020] The chiller 501 is fixedly arranged on the left side of the outer wall of the vertical pipe 402, and the chiller 501 can transport cold water to the inside of the water pipe 502. The water pipe 502 is fixedly arranged at the bottom end of the chiller 501, and the other end of the water pipe 502 is connected to the bottom end of the left side of the vertical pipe 402. The cooling pipe 503 is fixedly arranged at the bottom end of the water pipe 502, and the cooling pipe 503 is arranged inside the vertical pipe 402. The hose 504 is wrapped around the outer wall of the outer shell 1, and the top of the hose 504 is connected to the top of the cooling pipe 503. The hose 504 can cool the three-soft catalyst 2 from the outer wall of the outer shell 1. Among them, the chiller 501 transports the cold water to the inside of the cooling pipe 503 through the water pipe 502 to cool the wind inside the vertical pipe 402. The material of the hose 504 is a high-temperature resistant soft material.

[0021] Working principle: When the three-way filter for formaldehyde production is used, the user first uses the first valve 3 to transport the mixed gas to the inside of the shell 1, and then filters the mixed air through the three-way catalytic converter 2. The filtered gas is discharged from the bottom end of the shell 1, and then filtered through the three-way catalytic converter 2. Since the temperature of the mixed gas during formaldehyde production is relatively high, the three-way catalytic converter is in a high temperature state for a long time, which affects its service life. When the three-way catalytic converter 2 needs to be cooled, the user first closes the first valve 3, and then opens the second valve 403. After opening, the user first controls the water cooler 501 to start working through the external control unit, and transports cold water to the inside of the water pipe 502, and then transports the cold water to the cooling pipe 503 and the inside of the hose 504 through the water pipe 502, and then the user controls the external control unit Yuankai controls the fan 401 to start working. When the fan 401 starts working, the outside air enters the interior of the vertical pipe 402 through the fan, and then the cold air emitted by the cold water inside the cooling pipe 503 will follow the outside air through the vertical pipe 402 into the interior of the horizontal pipe 404 and then be discharged through the exhaust pipe 405. The cold air inside the exhaust pipe 405 is blown toward the surface of the three-way catalytic converter 2 to cool it. The cold wind continuously blows toward the three-way catalytic converter 2 to cool the three-way catalytic converter 2, and also discharges part of the formaldehyde attached to the inside of the three-way catalytic converter 2. Then, the cold air cooperates with the cold water inside the hose 504 to effectively cool the three-way catalytic converter 2. After the cooling work is completed, the user closes the second valve 403, and then closes the fan 401 and the chiller 501 at the same time.
