Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a spray-type waste gas treatment device. Background Technology

[0002] A spray-type waste gas treatment device is used to treat industrial waste gas. Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid mist, lead and mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via various pathways; some cause direct harm, while others have a cumulative effect, further jeopardizing human health. Different substances have different effects; therefore, spray-type waste gas treatment devices are crucial for waste gas treatment.

[0003] Conventional spray-type exhaust gas treatment devices filter and purify the waste gas, then use airflow to transport it to downstream equipment, resulting in relatively limited efficiency in treating the exhaust gas.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a spray-type waste gas treatment device. Utility Model Content

[0005] The purpose of this invention is to provide a spray-type waste gas treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spray-type exhaust gas treatment device, comprising a circulation box and a top cover, wherein a spray tower is vertically installed on the top of the circulation box, the top cover is installed on the top of the spray tower, and a demisting component is installed at the upper part of the interior of the spray tower, and two sets of spray components are vertically arranged directly below the demisting component. The top cover includes a support cylinder, an exhaust duct, a disinfection filter, and a fan. The exhaust duct is vertically installed at the top of the support cylinder, and a disinfection filter is installed in the middle of the top of the exhaust duct, and a fan is installed below the disinfection filter.

[0007] Furthermore, the circulation tank includes a water storage tank, a maintenance door, a support frame, and a precision filter. A maintenance door is installed at one end of the top of the water storage tank, and a support frame is provided on one side of the maintenance door. A precision filter is installed in the middle of the support frame. The support frame is arranged in a circular structure and communicates with the interior of the water storage tank. The precision filter is horizontally installed at the upper end of the interior of the support frame.

[0008] Furthermore, the spray tower includes a main tower body, a maintenance observation window, an air inlet pipe, a booster pump, and a filter pipe. A maintenance observation window is installed on one side surface of the main tower body, and an air inlet pipe is installed at the lower end of the side of the main tower body away from the maintenance observation window. A booster pump is installed at the lower end of the other side of the main tower body, and a filter pipe is vertically connected to the top of the booster pump.

[0009] Furthermore, the bottom of the main tower body is connected and fixed to the support frame through a flange structure, and three sets of maintenance observation windows are arranged vertically and equidistantly on the side of the main tower body. The bottom of the booster pump is connected to the inside of the water storage tank through a pipe.

[0010] Furthermore, the support cylinder is welded to the main tower body, and the exhaust duct and the support cylinder are integrally structured. The fan is mounted on the upper part of the exhaust duct, and a flange structure is provided at the top of the exhaust duct.

[0011] Furthermore, the demisting assembly includes a packing frame, a demisting filter, and a packing body. The demisting filter is horizontally installed on both the upper and lower sides of the packing frame, and the packing body is filled inside the packing frame.

[0012] Furthermore, the spray assembly includes a support ring frame, an electric adjustment frame, an atomizing nozzle, a connecting pipe, and an external connecting pipe. The electric adjustment frame is installed at the bottom of the support ring frame, and the atomizing nozzle is installed at the end of the electric adjustment frame away from the support ring frame. The connecting pipe is installed on the inner wall of the support ring frame, and an external connecting pipe is installed at the top of one end of the connecting pipe.

[0013] Furthermore, the end of the outer tube furthest from the connecting tube is connected to the filter tube, and the connecting tube and the outer tube are welded together. The connecting tube is connected to the top of the atomizing nozzle through a metal hose, and the electric adjustment frame and the atomizing nozzle are arranged in a ring array with the support ring frame as the center.

[0014] This utility model provides a spray-type waste gas treatment device, which has the following beneficial effects:

[0015] 1. This utility model features a top cover installed on the top of a spray tower. Gas treated by the spray and demisting components enters the space between the main tower body and the support cylinder. Under the operation of the fan, the airflow is rapidly guided and discharged through the exhaust duct from the interior of the top cover, then blown to downstream equipment. As the airflow moves, it passes through a sterilization filter installed on the top of the exhaust duct, further filtration and purification. This structure not only rapidly guides the treated waste gas, increasing the treatment speed, but also maximizes the treatment effect, providing excellent assistance to downstream gas treatment.

[0016] 2. This utility model, by installing a precision filter screen in the middle of the support frame on one side of the top of the water storage tank, allows the liquid inside the water storage tank to be transported to the interior of the spray assembly under the operation of the booster pump. During this process, the filter pipe connected to the booster pump is filtered to prevent pipe blockage. Under the operation of the spray assembly, the liquid is atomized, encapsulating impurities in the waste. Under the action of gravity, the atomized water droplets fall onto the precision filter screen directly below. The precision filter screen can collect and absorb the water mist containing impurities, thereby purifying the water mist so that the liquid can be recycled, reducing the operating cost of the device. At the same time, the filter pipe can also purify and filter the liquid flowing into the water storage tank again, thus ensuring the cleanliness of the recycled water. This avoids negative impacts on the internal pipes of the device and ensures the removal effect of impurities in the waste gas after atomization spraying. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 4 As shown, a spray-type exhaust gas treatment device includes a circulation box 1 and a top cover 3.

The top cover 3 includes a support cylinder 301, an exhaust duct 302, a disinfection filter 303, and a fan 304. The exhaust duct 302 is vertically installed on the top of the support cylinder 301, and the disinfection filter 303 is installed in the middle of the top of the exhaust duct 302. The fan 304 is mounted below the disinfection filter 303. The support cylinder 301 is welded to the main tower body 201, and the exhaust duct 302 and the support cylinder 301 are integrally structured.

The demisting component 4 includes a packing frame 401, a demisting filter 402 and a packing body 403. The demisting filter 402 is horizontally installed on both the upper and lower sides of the packing frame 401, and the packing body 403 is filled inside the packing frame 401. When the gas treated by the spray component 5 and the demisting component 4 enters the space between the main tower body 201 and the support cylinder 301, the airflow will be quickly guided under the operation of the fan 304 and discharged through the exhaust duct 302 into the interior of the entire top cover 3, and then blown to the downstream equipment. As the airflow moves, it will pass through the disinfection filter 303 installed at the top of the exhaust duct 302, which can filter and purify the airflow again.

[0025] like Figures 1 to 4As shown, the circulation tank 1 includes a water storage tank 101, a maintenance door 102, a support frame 103, and a precision filter 104. A maintenance door 102 is installed at one end of the top of the water storage tank 101, and a support frame 103 is provided on one side of the maintenance door 102. A precision filter 104 is installed in the middle of the support frame 103. The support frame 103 is arranged in a circular structure and communicates with the interior of the water storage tank 101. The precision filter 104 is horizontally installed at the upper end of the interior of the support frame 103. The spray tower 2 includes a main tower body 201, a maintenance observation window 202, an air inlet pipe 203, a booster pump 204, and a filter pipe 205. The main tower body 201... A maintenance observation window 202 is installed on one side of the main tower body 201, and an air inlet pipe 203 is installed on the lower end of the side of the main tower body 201 away from the maintenance observation window 202. A booster pump 204 is installed on the lower end of the other side of the main tower body 201, and a filter pipe 205 is vertically connected to the top of the booster pump 204. The bottom of the main tower body 201 is connected and fixed to the support frame 103 through a flange structure. Three sets of maintenance observation windows 202 are vertically and equidistantly arranged on the side of the main tower body 201. The bottom of the booster pump 204 is connected to the inside of the water storage tank 101 through a pipe. The spray assembly 5 includes a support ring frame 501 and an electric adjustment frame 50. 2. Atomizing nozzle 503, connecting pipe 504, and outer pipe 505; an electric adjusting bracket 502 is installed at the bottom of the support ring frame 501, and the atomizing nozzle 503 is installed at the end of the electric adjusting bracket 502 away from the support ring frame 501; a connecting pipe 504 is installed on the inner wall of the support ring frame 501, and an outer pipe 505 is installed at the top of one end of the connecting pipe 504; the end of the outer pipe 505 away from the connecting pipe 504 is connected to the filter pipe 205, and the connecting pipe 504 and the outer pipe 505 are welded together; furthermore, the connecting pipe 504 is connected to the top of the atomizing nozzle 503 through a metal flexible hose. The electric adjustment frame 502 and the atomizing nozzle 503 are arranged in a ring array with the support ring frame 501 as the center. A precision filter screen 104 is installed in the middle of the support frame 103 on the top side of the water tank 101. Under the operation of the booster pump 204, the liquid inside the water tank 101 is transported to the inside of the spray assembly 5. During this period, the filter pipe 205 connected to the booster pump 204 is filtered to prevent the pipe structure from becoming blocked. The precision filter screen 104 can collect and absorb water mist containing impurities, thereby purifying the water mist so that the liquid can be recycled.

[0026] In summary, as Figures 1 to 4 As shown, when the spray-type exhaust gas treatment device is in use, the exhaust gas is first transported to the interior of the entire circulation box 1 through the air inlet pipe 203 on one side of the main tower body 201. At this time, the fan 304 in the top cover 3 and the booster pump 204 on one side of the main tower body 201 will operate synchronously. The fan 304 operating inside the exhaust duct 302 will drive the airflow inside the top cover 3 and the spray tower 2, so that the exhaust gas input at the bottom of the main tower body 201 will be driven upward.

[0027] At this time, the booster pump 204 will draw water from the water storage tank 101 and transport it into the spray assembly 5 through the filter pipe 205. At this time, with the transport of the external pipe 505 and the connecting pipe 504, the water will be gradually transported to the atomizing nozzle 503 connected to the connecting pipe 504. Under the action of the atomizing nozzle 503, the water will be rapidly atomized. At the same time, under the operation of the electric adjustment frame 502, the multiple atomizing nozzles 503 arranged in a ring array will swing left and right within a certain range to ensure that the exhaust gas transported into the bottom of the entire circulation box 1 is covered to the maximum extent.

[0028] As the spray assembly 5 operates, impurities in the exhaust gas are filtered by water mist and fall into the precision filter 104 installed in the middle of the support frame 103 under gravity, thereby collecting and purifying the water mist, and finally returning it to the interior of the water storage tank 101. The operator can inject the agent used to treat the exhaust gas into the interior of the water storage tank 101 through the maintenance door 102.

[0029] Under the treatment of the spray assembly 5, the purified exhaust gas enters the packing frame 401 filled with the packing body 403. The demister filters 402 at the upper and lower ends of the packing frame 401 assist the packing body 403 in purifying the waste. After passing through the demister assembly 4, the treated gas enters the support cylinder 301. Under the operation of the fan 304, the gas is guided to the downstream equipment. At this time, it will pass through the disinfection filter 303 at the top of the exhaust duct 302 again, thus being purified again, so that the downstream equipment can carry out subsequent gas treatment.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
