Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and specifically relates to a waste gas collection, purification and treatment device. Background Technology

[0002] During the production of PVC gloves, the exhaust fumes often contain a large amount of dust. If this dust is not treated in time, it will accumulate on the equipment, shortening the service life of the equipment. At the same time, the working environment of the workers is also relatively poor. Most of the existing treatment equipment filters the dust through simple physical filtration, which can only filter some larger dust particles, and the purification effect is not good. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a waste gas collection and purification device that uses a dust suppression zone, a spray assembly, a filter layer, and a purification layer in combination to achieve the best dust purification effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A waste gas collection and purification device includes a housing, an air inlet, a dust collection zone, a guide plate, a filter layer, a spray assembly, a purification layer, and a suction fan. The air inlet is fixedly connected to the outer wall of the housing, allowing waste gas to enter the housing while simultaneously connecting to external equipment, enabling the waste gas to directly enter the housing through the air inlet and preventing waste gas escape. A dust collection zone is provided at the bottom of the housing. The guide plate is fixedly connected to the inner wall of the housing and placed above the dust collection zone. The filter layer is fixedly connected to the inner wall of the housing and located above the guide plate. A spray assembly is fixedly connected above the filter layer and to the inner wall of the housing. A purification layer is fixedly provided above the spray assembly. A suction fan is fixedly provided at the top of the housing.

[0006] After the exhaust fan is turned on, a negative pressure zone is created inside the casing, allowing the exhaust gas to quickly enter the casing through the air inlet. The guide plate extends the path of the exhaust gas in the dust settling zone, thus maximizing the settling of dust. As the exhaust gas flows upward to the filter layer, the water mist sprayed by the spray assembly combines with the exhaust gas, further dislodging fine dust particles as it passes through the filter layer. When the exhaust gas continues to rise to the purification layer, it undergoes further adsorption and purification before being discharged through the exhaust fan.

[0007] Preferably, the dust suppression zone consists of several dust suppression columns, which are fixedly connected to the bottom of the casing. Each dust suppression column includes a vent, a support, and a baffle. Several vents are provided on the side wall of the support, and a baffle is fixedly provided on the other side wall of the support. Exhaust gas can flow through the vents on the support and the gap between the dust suppression columns. During the flow, dust will accumulate downwards under the action of gravity. The baffle can extend the path of the exhaust gas and increase the obstacles, which can make large dust particles in the exhaust gas fall off completely.

[0008] Preferably, the filter layer includes a fixed frame and filter cotton. The fixed frame is fixedly connected to the inner wall of the housing. The fixed frame is hollow inside and has several through holes. The filter cotton is installed inside the fixed frame. The fixed frame with through holes allows the exhaust gas to flow, and the filter cotton can filter the fine dust in the exhaust gas.

[0009] Preferably, the spray assembly includes a spray plate, spray heads, a water inlet pipe, and a bracket. The bracket is fixedly connected to the inner wall of the housing, and the spray plate is fixedly connected to the bracket. The bottom of the spray plate is provided with a plurality of spray heads, and the top of the spray plate is provided with a water inlet pipe. During use, after the spray heads spray water mist, the fine particles in the exhaust gas combine with the water mist and settle, thereby achieving the effect of water mist purification.

[0010] Preferably, the purification layer is provided with activated carbon, which further adsorbs the waste gas, making the waste gas treatment and purification more thorough.

[0011] Preferably, the outer wall of the casing is provided with a drain pipe, which can be opened to drain the accumulated water after the water at the bottom of the casing reaches a certain amount.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] The dust settling zone, composed of several dust settling columns, can quickly settle large dust particles in the exhaust gas. Then, the water mist emitted by the spray components combines with the fine particles, which can further filter out the fine dust as it passes through the filter cotton. Finally, the activated carbon in the purification layer further adsorbs and purifies the gas, thus achieving the best purification effect in the treatment of dusty flue gas.

The guide plate 4 extends the path of the exhaust gas in the dust settling zone 3, thereby allowing as much dust as possible to fall in the dust settling zone 3.

When passing through the filter layer 5, the fine dust particles are further separated. When the exhaust gas continues to rise to the purification layer 7, the exhaust gas is further adsorbed and purified. After completion, it is discharged through the suction fan 8.

Exhaust gas can flow through the gap between the vent 311 on the support column 312 and the dust suppression column 31. During the flow, dust will accumulate downwards under the action of gravity. The baffle 313 can extend the path of exhaust gas and increase the obstacles, which can make large dust particles in the exhaust gas fall off completely.
