Description
A waste gas absorption device during sludge dissolution process Technical Field
[0001] This utility model belongs to the field of waste gas absorption technology, and in particular relates to a waste gas absorption device in the process of sludge dissolution. Background Technology
[0002] Electroplating sludge is a precipitate produced during the treatment of electroplating wastewater. It is mainly composed of heavy metal hydroxides such as copper, chromium, and nickel. It has a complex composition and contains high concentrations of heavy metals. It is characterized by high water content and easy migration of heavy metals. If not treated properly, it can cause serious harm to the environment and human health. Its main components include heavy metal compounds (such as chromium, iron, nickel, copper, zinc, etc.), gypsum (calcium sulfate), water-soluble salts, and impurities. The water content of newly generated sludge can reach 75%-80%. The main treatment methods for electroplating sludge include solidification and stabilization, biological treatment, thermal treatment, and resource utilization. Solidification and stabilization involves adding solidifying agents such as cement and fly ash to seal the harmful substances in the sludge and reduce the leaching rate of heavy metals.
[0003] Electroplating sludge needs to be dissolved during treatment, which generates waste gas containing a large amount of heavy metal ions. This waste gas accumulates in the factory premises, and most factories are not equipped with waste gas absorption devices, usually directly using exhaust fans to discharge the waste gas into the outside air. This pollutes the environment near the factory. Therefore, it is necessary to provide a waste gas absorption device for the sludge dissolution process to solve the above problems. Summary of the Invention
[0004] The technical content of this utility model is to provide a waste gas absorption device during the sludge dissolution process.
[0005] To address the aforementioned problems, this utility model provides a waste gas absorption device during sludge dissolution, comprising a barrel body, a solution tank installed at the bottom of the barrel body, a base installed at the bottom of the solution tank, four sets of casters installed at the bottom of the base, six sets of reinforcing blocks symmetrically installed at the top of the base, two sets of connecting pipes symmetrically installed on the outer side of the solution tank, a connecting ring installed at the top of the solution tank, a connecting groove opened at the bottom of the barrel body, an absorption chamber installed at the top of the barrel body via a fixing ring, a sealing plate installed on the side of the absorption chamber, a sealing ring installed on the outer side of the sealing plate, a partition plate installed at the bottom of the absorption chamber, a through hole opened on the partition plate, an air suction pump installed at the top of the absorption chamber via a fixing plate, a filter plate installed at the top of the air suction pump, an air inlet pipe installed at the bottom of the air suction pump, a heating pipe installed inside the solution tank, and four sets of fixing blocks symmetrically installed on the side of the partition plate.
[0006] As a further solution of this utility model, the connecting ring provided at the top of the solution pool is inserted into the connecting groove opened at the bottom of the barrel. Six sets of fixing bolts are symmetrically installed on the outer side of the lower end of the barrel. The fixing bolts pass through the barrel and the connecting ring, thereby fixing the connecting ring in the connecting groove.
[0007] As a further solution of this utility model, the side of the reinforcing block provided on the top of the base is fixedly connected to the outside of the solution pool. The connection between the base and the solution pool can be effectively increased by six sets of reinforcing blocks.
[0008] As a further solution of this utility model, the connecting pipe is connected to the interior of the solution pool, and a pipe cap is installed on the connecting pipe to close it.
[0009] As a further solution of this utility model, a set of fixing rings is installed on the top outer side of the barrel and the bottom outer side of the absorption chamber. The two sets of fixing rings are fixedly connected by six sets of fixing bolts. The diameter of the partition is the same as the inner diameter of the barrel. The fixing block installed on the outer side of the partition is fixedly installed in the fixing groove opened at the bottom of the absorption chamber by fixing bolts. The partition is fixedly installed inside the bottom of the absorption chamber. The bottom of the partition is flush with the bottom of the absorption chamber. The outer side of the absorption chamber is set as an open structure. The sealing plate is installed at the outer opening of the absorption chamber by fixing bolts. The sealing plate is equipped with a handle so as to remove the sealing plate from the absorption chamber.
[0010] As a further solution of this utility model, the fixing plate is set on the bottom outside of the suction pump, and the air inlet pipe is set in the through hole opened in the top center of the absorption chamber. The suction pump is connected to the inside of the absorption chamber, and the suction pump can absorb the waste gas in the factory workshop into the inside of the absorption chamber.
[0011] As a further solution of this utility model, the filter plate is installed on the top inner side of the suction pump, which can prevent debris from entering the interior of the suction pump.
[0012] Compared with related technologies, the waste gas absorption device provided by this utility model in the sludge dissolution process has the following beneficial effects:
[0013] 1. This utility model involves installing a solution tank at the bottom of the tank, with two sets of connecting pipes installed on the solution tank. The top set of connecting pipes allows waste gas absorption liquid to be injected into the solution tank, while the bottom set of connecting pipes allows the waste gas absorption liquid that has absorbed the waste gas to be discharged from the solution tank. After being absorbed by the absorption pump installed at the top of the tank, the waste gas enters the interior of the tank and undergoes a dissolution reaction with the waste gas absorption liquid, thereby achieving the absorption of the waste gas. A heating pipe is installed in the solution tank to heat the waste gas absorption liquid, increasing its absorption effect on the waste gas and preventing waste gas from polluting the environment.
[0014] 2. This utility model features an absorption chamber installed at the top of the barrel, with a partition at the bottom of the absorption chamber. This allows absorbent materials such as activated carbon to be placed inside the absorption chamber. The waste gas entering the absorption chamber can be initially absorbed by the activated carbon, thus achieving preliminary treatment. The partition has through holes, allowing the waste gas to enter the interior of the barrel through the partition. The partition is installed inside the bottom of the absorption chamber by fixing bolts, making it very easy to install and remove, thus facilitating the replacement of the activated carbon in the absorption chamber.

[0023] Preferably, the connecting ring 7 set at the top of the solution pool 2 is inserted into the connecting groove opened at the bottom of the barrel 1. Six sets of fixing bolts are symmetrically installed on the outer side of the lower end of the barrel 1. The fixing bolts pass through the barrel 1 and the connecting ring 7, thereby fixing the connecting ring 7 in the connecting groove, so that the solution pool 2 and the barrel 1 are fixedly assembled together. The sealing of the connection between the two can be ensured by the connecting ring 7.
[0024] Preferably, the side of the reinforcing block 5 on the top of the base 3 is fixedly connected to the outside of the solution pool 2. The six sets of reinforcing blocks 5 can effectively increase the connection between the base 3 and the solution pool 2, so that the base 3 will not separate from the solution pool 2. The casters 4 installed at the bottom of the base 3 can make the device have good mobility, so that the user can push the device to move in the factory.
[0025] Preferably, the connecting pipe 6 is connected to the interior of the solution tank 2. Waste gas absorption liquid can be injected into the interior of the solution tank 2 through the top set of connecting pipes 6, and the waste gas absorption liquid that has absorbed waste gas in the solution tank 2 can be discharged from the solution tank 2 through the bottom set of connecting pipes 6. The connecting pipe 6 is equipped with a pipe cap, so as to close the connecting pipe 6. The waste gas absorption liquid in the solution tank 2 can be heated by the heating pipe 16 installed in the solution tank 2 to increase its absorption effect on waste gas.
[0026] Preferably, a set of fixing rings is installed on the top outer side of the barrel 1 and the bottom outer side of the absorption chamber 8. The two sets of fixing rings are fixedly connected by six sets of fixing bolts, thereby fixing the absorption chamber 8 on the top of the barrel 1. The diameter of the partition 11 is the same as the inner diameter of the barrel 1. The fixing block 17 installed on the outer side of the partition 11 is fixedly installed in the fixing groove opened at the bottom of the absorption chamber 8 by fixing bolts, thereby fixing the partition 11 inside the bottom of the absorption chamber 8. The bottom of the partition 11 is flush with the bottom of the absorption chamber 8. The outer side of the absorption chamber 8 is set as an open structure so that absorbent materials such as activated carbon can be placed into the interior of the absorption chamber 8. The sealing plate 9 is installed at the outer opening of the absorption chamber 8 by fixing bolts, thereby sealing the absorption chamber 8. The sealing ring 10 installed on the outer side of the sealing plate 9 can further increase the sealing degree of the absorption chamber 8, so that the waste gas entering the interior of the absorption chamber 8 will not escape. The sealing plate 9 is equipped with a handle so that the sealing plate 9 can be removed from the absorption chamber 8.
[0027] Preferably, the fixing plate 12 is set on the bottom outside of the suction pump 13, and the air inlet pipe 15 is set in the through hole opened in the middle of the top of the absorption chamber 8. The air inlet pipe 15 connects the suction pump 13 and the interior of the absorption chamber 8. The suction pump 13 can absorb the waste gas in the factory workshop into the interior of the absorption chamber 8. Then, the waste gas is initially absorbed by the activated carbon. Then, the waste gas can enter the interior of the tank 1 through the through hole opened on the partition plate 11. The waste gas reacts with the waste gas absorption liquid in the solution tank 2, thereby dissolving and absorbing the waste gas, thus realizing the absorption and treatment of the waste gas generated during the sludge dissolution process. By removing the partition plate 11 from the bottom of the absorption chamber 8, the activated carbon in the absorption chamber 8 can be replaced, which is very convenient to operate.
[0028] Preferably, the filter plate 14 is installed on the top inner side of the suction pump 13. The filter plate 14 can prevent debris in the factory from entering the suction pump 13 during the process of absorbing waste gas, thereby ensuring that the structure of the device will not be damaged.
