Description

[0002] In the process of waste gas treatment, corresponding waste gas spray tower equipment is required to spray the waste gas. Referring to the authorized announcement number CN114570185B, a waste gas spray tower equipment for waste gas treatment includes a centrifugal fan, a spray tower, an inlet pipe and an exhaust pipe. The inlet pipe is equipped with a first rotating shaft that cooperates with the centrifugal fan. The first rotating shaft is equipped with several first electromagnets, which can automatically collect iron filings in the waste gas and use the iron filings in the waste gas to generate iron salts. As described in the above patent, when using existing waste gas spray tower equipment for waste gas treatment, the waste gas extraction operation is often interrupted during the cleaning process of the waste gas filter end of the device in order to reduce waste gas leakage. This affects the waste gas treatment efficiency. At the same time, the filter end of the device mostly only scrapes and cleans the impurities retained on the surface. The impurities retained in the filter holes are difficult to clear in time, which will still cause blockage and affect subsequent waste gas treatment operations. Utility Model Content

[0015] Beneficial effects

[0016] This utility model provides a waste gas spray tower device for waste gas treatment. Compared with the prior art, it has the following advantages:

[0017] 1. This waste gas spray tower equipment for waste gas treatment, by setting a first three-way valve and regulating components in the device, allows the waste gas to pass through the shell before being introduced into the main body of the spray tower. The filter plate filters the solid impurities in the gas. The first three-way valve, in conjunction with the exhaust pipe and exhaust pump, enables the switching of the waste gas extraction direction, facilitating the switching of the shell and filter plate used for filtering waste gas impurities. While not affecting the device's filtration of impurities in the waste gas, it also facilitates the subsequent cleaning operation of the original filter plate. The motor, bevel gear assembly, scraper, recovery cylinder, liquid pump, second three-way valve, conduit, and spray block work together to scrape, clean, and unclog the filter plate previously used to treat waste gas impurities, preventing the filter end from becoming clogged and difficult to clear, thus affecting subsequent filtration operations and improving cleaning efficiency.

[0018] 2. The exhaust gas spray tower equipment for exhaust gas treatment, by installing a baffle inside the device and adjusting the vertical height of the two sets of baffles by two sets of cylinder assemblies respectively, achieves a closed state of the inside of the shell relative to the inlet pipe and outlet pipe, which helps subsequent cleaning operations and reduces the impact of exhaust gas introduction on the cleaning of the filter end inside the shell.

A recovery cylinder 665 is threadedly connected to the bottom of the housing 62 near the left side of the filter plate 663. A feeding trough is provided on the upper side of the housing 62 near the recovery cylinder 665. The surface of the filter plate 663 has several filter holes. A protective shell is provided on the outer side of the housing 62 near the bevel gear assembly 662. The driving bevel gear in the bevel gear assembly 662 is coaxially and fixedly connected to the output end of the motor 661.

[0030] The main difference between the second implementation method and the first implementation method is that:

[0031] The barrier 65 includes a cylinder assembly 651 installed on the top edge of the housing 62. The bottom extension end of the cylinder assembly 651 is equipped with a partition 652 that is slidably connected to the inner side of the housing 62. The two partitions 652 in the two sets of barrier 65 are respectively close to the air inlet pipe 63 and the air outlet pipe 64. Two sets of square grooves that are slidably connected to the partitions 652 are provided in the interlayer on both sides of the housing 62. By adjusting the vertical height of the two sets of partitions 652 by the two sets of cylinder assemblies 651, the interior of the housing 62 is closed relative to the air inlet pipe 63 and the air outlet pipe 64, which helps with subsequent cleaning operations.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] In use, the user starts the air pump 3. The air pump 3 draws in the corresponding waste gas through the air extraction pipe 4, the first three-way valve 5, a set of outlet pipes 64, the housing 62, and the inlet pipe 63. When the waste gas passes through the housing 62, the filter plate 663 inside the housing 62 filters out large particulate impurities in the waste gas. Then, the waste gas is introduced into the spray tower body 2 by the air pump 3 for spray cleaning. The spray tower body 2 is existing technology, so its internal structure and working principle will not be described in detail. In the above process, the gas flow sensor in the air extraction pipe 4 detects the gas flow rate. When the gas flow rate is lower than a certain value, the first three-way valve 5 is reversed. At this time, the air pump 3 draws in the corresponding waste gas through the first three-way valve 5 and another set of outlet pipes 64. 4. The housing 62 and the intake pipe 63 draw in the corresponding exhaust gas. At this time, the cylinder assembly 651, which is far away from the two sides of the housing 62, drives the two sets of partitions 652 to seal the two sides of the housing 62. The motor 661 and the bevel gear assembly 662 cooperate to drive the filter plate 663 to rotate. The scraper 664 scrapes the impurities stuck on the surface of the filter plate 663. The scraped impurities fall into the recovery cylinder 665. Then, the second three-way valve 672 is reversed to start the liquid pump 671. The liquid pump 671 draws in the external cleaning liquid and uses it to clear the filter holes in the rotating filter plate 663 through the second three-way valve 672, the conduit 673, and the spray block 674. The mixture of cleaning liquid and blockage impurities falls into the recovery cylinder 665.
