[0030] The utility model discloses a constant humidity and temperature dust removal system for an isolation room of a powder room, comprising:

[0031] A circulating air duct, comprising an air inlet duct 1 and an exhaust duct 3. The air inlet duct 1 is arranged on the floor of the powder room isolation room and is used to absorb dust that falls on the floor. The exhaust duct 3 is arranged above the powder room isolation room and has a plurality of exhaust ports 4.

[0032] A cyclone tower 5 and a combined air conditioning unit 8 are sequentially connected between the air inlet duct 1 and the air exhaust duct 3; the cyclone tower 5 and the combined air conditioning unit 8 are arranged outside the isolation room of the powder room;

[0033] The cyclone tower 5 is connected to the air inlet duct 1 and removes dust from the air by centrifugal means of water flow;

[0034] The combined air conditioning unit 8 includes a filtering device and a drying and cooling device. The filtering device is connected to the cyclone tower 5 ; one end of the drying and cooling device is connected to the filtering device, and the other end is connected to the exhaust duct 3 .

[0035] Compared with the existing technology, in order to make the powder room isolation room have a constant temperature, constant humidity and clean working environment, the utility model innovatively uses the air inlet duct 1 to absorb the dust on the ground of the powder room isolation room, and then the cyclone tower 5 and the filter device remove the dust in the air, and uses the drying and cooling device to adjust the moisture and temperature in the air, and finally transports the air to the powder room isolation room to realize circulation, effectively improve the working environment in the powder room isolation room, and effectively control the dust content, humidity and temperature in the powder room isolation room, thereby ensuring the effect of the spraying process.

[0036] Furthermore, the swirl tower 5 includes a swirl barrel 6, which is connected to the air inlet duct 1. A nozzle (not shown) is provided on the top of the swirl barrel 6, and a water outlet is provided at the bottom of the swirl barrel 6. A circulating water tank (not shown) is provided outside the swirl barrel 6, which is connected to the water outlet. The circulating water tank is equipped with a water pump, which is connected to the nozzle via a pipe. The water pump transports water from the circulating water tank to the nozzle, and the water is sprayed into the swirl barrel 6 through the nozzle. The characteristics of the swirl tower 5 are used to separate dust suspended in the water flow.

[0037] Furthermore, a swirl tower air inlet 7 is provided on the outer side of the swirl barrel 6 , and the swirl tower air inlet 7 is communicated with the air inlet duct 1 .

[0038] It should be noted that the cyclone tower 5 is a commonly used physical separation device. Based on the principle of centrifugal force, it can effectively separate solid particles suspended in a fluid. The operating principle of the cyclone tower 5 can be summarized as follows: the liquid rotates within the tower, and the solid particles are forced to settle to the bottom of the tower under the action of centrifugal force, thus achieving the separation effect.

[0039] Furthermore, a primary filter 9 and a medium filter 10 are provided in the filtering device. When the air flows from the inside of the filtering device to the drying and cooling device, it passes through the primary filter 9 and the medium filter 10 in sequence. Since the air first passes through the cyclone tower 5 and then flows into the filtering device, the air is humid air with more moisture. By setting the primary filter 9 and the medium filter 10, and combining the treatment of air dust by the cyclone tower 5 in the previous process, the dust in the humid air is treated three times in total, effectively controlling the dust content in the air; in addition, the primary filter 9 and the medium filter 10 can also filter other fixed particles and other fixed substances in the humid air, thereby playing a role in cleaning the air.

[0040] Furthermore, the drying and cooling device includes a hot air blower (not shown) and a surface cooler 11. The air passes through the hot air blower and the surface cooler 11 in sequence and then enters the exhaust duct 3. The hot air blower is used to dry the moist air, and the surface cooler 11 is used to cool the dried air to control the humidity and temperature of the air flowing into the powder room isolation room, thereby controlling the humidity and temperature in the powder room isolation room.

[0041] Furthermore, the surface cooler 11 is connected to a chilled water unit 14, which includes a cold water storage tank 13, a refrigerator and a circulating water pipe 15. The surface cooler 11 is connected to the cold water storage tank 13 through the circulating water pipe 15 to form a loop. The refrigerator is used to cool the water in the cold water storage tank 13 to control the temperature of the air entering the powder room isolation room, thereby controlling the temperature in the powder room isolation room.

[0042] Furthermore, a blower 12 is provided on one side of the drying and cooling device close to the exhaust duct 3, and the blower 12 provides thrust for the processed air, thereby accelerating the speed at which the processed air enters the isolation room of the powder room.

[0043] Furthermore, the temperature within the powder booth is controlled between 10°C and 30°C. Within this range, powder adhesion, leveling, and curing properties are excellent. If the temperature is too low, the viscosity of the powder coating increases, making spraying difficult; if the temperature is too high, the powder coating is prone to sagging and orange peeling. Furthermore, an appropriate temperature also helps improve the working environment in the powder booth and reduce worker fatigue.

[0044] Furthermore, the humidity within the powder coating booth is controlled between 30% and 70%. Appropriate humidity helps maintain the cleanliness of the booth and reduces the impact of dust on equipment. Too low a humidity level prevents static electricity generated during the powder coating process from being released, increasing fire hazards. Too high a humidity level causes the powder coating to absorb moisture, affecting the coating's adhesion and weather resistance.

[0045] Furthermore, in order to avoid contamination of powder coating during the spraying process, the dust concentration in the isolation room of the powder room should be controlled at 10mg / m 3 Below, in order to keep the dust concentration in the powder room isolation room low.

[0046] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.

[0047] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
