Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and specifically to waste gas treatment equipment. Background Technology

[0002] Waste gas treatment equipment is used to separate pollutants from waste gas, enabling the waste gas to meet emission standards after a series of treatments. Waste gas treatment equipment includes a waste gas collection device, a spray tower, a dry-wet separation box, an activated carbon purification box, and an exhaust fan. The spray tower is used to remove harmful substances from the waste gas. Liquid is sprayed onto the waste gas through spray components within the spray tower body, absorbing and dissolving harmful substances. The packing layer in the spray tower increases the contact area between the waste gas and the spray liquid, improving waste gas treatment efficiency.

[0003] The spray assembly includes multiple spray pipes, and the packing layer includes a grid plate that supports the packing balls. During installation, the spray pipes and grid plate need to be welded to the inner wall of the spray tower body first, then the grid plate needs to be welded to the inner wall of the spray tower body, and then multiple packing balls need to be laid on the grid plate. This requires multiple welding processes, making the installation quite complicated. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a waste gas treatment device that can reduce the frequency of welding, simplify installation, and improve installation efficiency.

[0005] The technical solution adopted by this utility model is as follows: a waste gas treatment device, including a spray tower body, multiple spray components for spraying liquid, and multiple grid plates for supporting packing balls. The inner wall of the spray tower body is provided with multiple support components for simultaneously supporting and locking the spray components and grid plates.

[0006] The principle of the technical solution:

[0007] Multiple support components are first installed on the inner wall of the spray tower body. Then, the spray components and grating are placed directly on the support components. The support components support and lock the spray components and grating respectively, thus completing the installation of the spray components and grating.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention, through the setting of support components, can connect the spray assembly, the grid plate and the spray tower body, reducing the frequency of welding, simplifying installation and improving installation efficiency.

[0010] In a preferred embodiment of this utility model, the support component includes a support ring and a plurality of circumferentially arranged limiting blocks. The outer surface of the support ring is connected to the inner wall of the spray tower body, and the inner surface of the support ring is connected to the limiting blocks. The inner wall of the spray tower body, the support ring, and the plurality of limiting blocks enclose a limiting space that extends through the top.

[0011] The spray assembly includes a first connecting ring, and the grid plate includes a second connecting ring. Both the first and second connecting rings can be inserted into the limiting space and abut against the inner wall of the spray tower body and the surface of the limiting block opposite to the inner wall of the spray tower body, respectively. The first connecting ring can fit into the second connecting ring.

[0012] Beneficial effects: The support ring and multiple limiting blocks, together with the inner wall of the spray tower body, can provide support and limiting for the first connecting ring and the second connecting ring, which indirectly supports and limits the spray assembly and the grid plate. The first connecting ring and the second connecting ring can be directly placed into the limiting space to complete the installation of the spray assembly and the grid plate. The installation is simple and improves the installation efficiency.

[0013] In a preferred embodiment of the present invention, the spraying assembly further includes a main pipe located in the radial direction of the first connecting ring and a plurality of branch pipes spaced apart along the length of the main pipe. The plurality of branch pipes are all perpendicular to and connected to the main pipe. The main pipe and the plurality of branch pipes are all connected to the inner surface of the first connecting ring. Each branch pipe is provided with a plurality of nozzles for spraying liquid.

[0014] In a preferred embodiment of this utility model, the branch pipe can be located between two adjacent limiting blocks and engaged with the two adjacent limiting blocks.

[0015] Beneficial effect: The branch pipe is located between two adjacent limit blocks and is engaged with the two adjacent limit blocks, which can improve the stability of the connection between the spray assembly and the spray tower body.

[0016] In a preferred embodiment of the present invention, a plurality of nozzles are respectively disposed at the end of the branch pipe and at the location of the branch pipe between the main pipe and the first connecting ring. The nozzles disposed at the end of the branch pipe are inclined and face inward. Two nozzles are disposed at the location of the branch pipe between the main pipe and the first connecting ring. Both nozzles are inclined, with one nozzle facing inward and the other nozzle facing outward.

[0017] Beneficial effects: The nozzles at the end of the branch pipe spray liquid inward, and the two nozzles on the branch pipe located on one side of the main pipe spray liquid inward and outward, so that the liquid flow from the nozzles at the end of the branch pipe and the multiple nozzles on the branch pipe crosses, ensuring that the sprayed liquid covers the entire cross section of the grid plate and improves the efficiency of exhaust gas treatment.

[0018] In a preferred embodiment of the present invention, the grating plate includes multiple support bars arranged in rows and columns, and the ends of the multiple support bars are respectively connected to the inner surface of the second connecting ring.

[0019] In a preferred embodiment of this utility model, the support bar can be located between two adjacent limiting blocks and engaged with the two adjacent limiting blocks.

[0020] Beneficial effects: The support bar is located between two adjacent limiting blocks and engages with the two adjacent limiting blocks, which can improve the stability of the connection between the grating plate and the spray tower body. Attached Figure Description
