Description

Technical Field

[0001] This utility model relates to the field of gas treatment technology, and in particular to a gas treatment device for environmental protection engineering. Background Technology

[0002] Environmental protection engineering hazardous gas treatment devices mainly refer to environmental protection equipment that uses different process technologies to recover or remove or reduce the harmful components of emitted gases, thereby protecting the environment and purifying the air. With the development of science and technology and industry, many factories emit a large amount of waste gas every day. These waste gases contain a large number of harmful substances and are accompanied by high temperatures, which will cause great damage to our environment. In order to protect the environment, these hazardous gases must be treated. Existing hazardous gas treatment devices mostly treat hazardous gases through filtration and incineration.

[0003] Existing filtration equipment is poorly designed and its filtration effect is unsatisfactory. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a gas treatment device for environmental protection engineering. This utility model is achieved through the following technical solution: An environmental engineering gas treatment device includes a rectangular shell, which comprises several shell plates, with a vacuum insulation cavity formed between adjacent shell plates. A vacuum insulation board is laid at the bottom of the shell. An air inlet is provided on the left side of the shell, and an air outlet is provided on the right side. From left to right, a gas filtration device, a gas cooling device, and an air supply device are arranged in sequence inside the shell. The gas filtration device includes a filter frame with several filter grids arranged in a grid pattern on the filter frame. Each filter grid contains a filter block, and the front and back surfaces of the filter block are wavy.

[0005] The gas cooling device includes a chassis located at the bottom of the housing, and a coil connected end to end horizontally arranged above the chassis. The rear ends of the coils are all fixed to a clamping plate, which is fixedly connected to the housing.

[0006] The air supply device includes an induced draft fan, and the induced draft fan outlet is installed at the air outlet of the housing.

[0007] As a preferred embodiment, the filter block is made of activated carbon.

[0008] As a preferred embodiment, the lower part of the coil is connected to a water inlet pipe, the upper part of the coil is connected to a water outlet pipe, and the connection points of the water inlet pipe and the water outlet pipe with the shell are provided with annular pipe seals.

[0009] As a preferred embodiment, the induced draft fan is connected to a geared motor via a drive.

[0010] As a preferred embodiment, the coil is made of copper.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: In use, exhaust gas from the factory workshop enters the housing through the air inlet. It is then purified by a gas filtration device, which removes pollutants, impurities, and odors. The filter blocks of the gas filtration device have a wavy surface on both the front and back, increasing the contact area with the gas and improving filtration efficiency. The purified gas then enters a gas cooling device for further cooling. During operation, refrigerant is introduced into the coil to cool the gas before it is discharged outdoors by an induced draft fan. This device not only purifies the exhaust gas from the factory workshop but also reduces its emission temperature, further improving air quality. Simultaneously, it facilitates the discharge of high-temperature gas from the factory workshop, thus regulating the temperature within the workshop.

[0012] The shell includes several shell plates, with a vacuum insulation cavity formed between adjacent shell plates. The bottom of the shell is lined with a vacuum insulation board, which can prevent the gas cooling device from exchanging heat with the outside air and ensure the cooling effect on the exhaust gas.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: An environmental engineering gas treatment device includes a rectangular shell 1, which comprises several shell plates 101, with a vacuum insulation cavity 102 formed between adjacent shell plates 101. A vacuum insulation board 2 is laid at the bottom of the shell 1. An air inlet 103 is provided on the left side of the shell 1, and an air outlet 104 is provided on the right side. From left to right, a gas filtration device 3, a gas cooling device 4, and an air supply device 5 are arranged in sequence inside the shell 1. The gas filtration device 3 includes a filter frame 31, on which several filter grids 32 are arranged in a grid pattern. Each filter grid 32 contains a filter block 33, and the front and back surfaces of the filter block 33 are both wavy.

[0015] The gas cooling device 4 includes a chassis 41 located at the bottom of the housing 1. Above the chassis 41, there are horizontally arranged coils 42 connected end to end. The rear ends of the coils 42 are all fixed on a clamping plate 46, which is fixedly connected to the housing 1.

[0021] When the gas treatment equipment used in this environmental protection project is in operation, the exhaust gas from the factory workshop enters the housing 1 through the air inlet 103. In the housing 1, it is purified by the gas filter device 3, which filters out pollutants, impurities, and odors. The front and back surfaces of the filter blocks 33 in the gas filter device 3 are wavy, which increases the contact area with the gas and improves filtration efficiency. The purified gas then enters the gas cooling device 4 for cooling. During operation, refrigerant is introduced into the coil 42 to cool the gas before it is discharged outdoors by the exhaust fan 51. This device not only purifies the exhaust gas from the factory workshop but also reduces the exhaust temperature, further improving air quality. Simultaneously, it removes high-temperature gas from the factory workshop, thus regulating the temperature within the workshop.

[0022] The shell 1 includes several shell plates 101, and a vacuum insulation cavity 102 is formed between two adjacent shell plates 101.
