Common methods include adsorption method, absorption method, catalytic combustion method, thermal combustion method, etc.

[0003] The patent with the patent publication number CN216630114U discloses a coking waste gas treatment device with an internal protection structure, including an exhaust gas pipeline. The exhaust gas pipeline includes a pipeline main body, a ceramic protection port, and an anti-corrosion coating. A filtering structure is fixedly installed in the middle of the exhaust gas pipeline. The filtering structure includes a hollow disk, a filling chamber, a limiting wire mesh disk, a feeding port, a sealing cover, a waste discharge pipe, and a sealing valve. One end of the exhaust gas pipeline is fixedly and hermetically welded to a waste gas treatment reaction furnace. The waste gas treatment reaction furnace includes a reaction furnace shell, a support foot frame, a filling and sealing door, a gas inlet and outlet pipe, a controllable valve, and a multi-layer reaction chamber. The coking waste gas treatment device described in this patent provides a certain degree of protection for the exhaust gas pipeline, can perform simple purification treatment on coking waste gas, and while ensuring that the coking waste gas can be completely treated, it can recycle coking waste gas to a certain extent.

[0004] Currently, the coking waste gas treatment devices on the market still have the following problems: When the waste gas treatment device treats waste gas, few devices provide protection for the internal gas. This may cause the internal gas in the device to be too much, resulting in different internal and external pressures, and then causing damage to the device shell. Therefore, it is necessary to design a coking waste gas treatment device with strong practicability and a pressure relief device. Summary of the Invention

[0005] The purpose of the present invention is to provide a coking waste gas treatment device with an internal protection structure to solve the problem proposed in the above background art that when the waste gas treatment device treats waste gas, few devices provide protection for the internal gas, which may cause the internal gas in the device to be too much, resulting in different internal and external pressures, and then causing damage to the device shell.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a coking waste gas treatment device with an internal protective structure, comprising a box body, a pressure relief device and a valve closing device are arranged on the left side of the box body, and a spray device and an adsorption device are arranged inside the box body; the pressure relief device comprises a pressure relief box, a pressure relief plate, a limit block and a pressure regulating assembly, the pressure relief box is fixed on the left side of the outer wall of the box body, and a through groove is opened on the left side of the box body and the right side of the inner wall of the pressure relief box. After the exhaust gas is injected into the box body, when the air pressure inside the box body is too large, the excess gas will be discharged through the through groove opened on the left side of the box body and the right side of the inner wall of the pressure relief box, and the pressure relief plate slides It is dynamically installed on the inner wall of the pressure relief box, and a through groove is provided on the front side of the pressure relief box. The pressure difference between the inside and outside of the box causes the pressure relief plate to rise under the action of pressure. When the pressure relief plate passes over the through groove provided on the front side of the pressure relief box, excess exhaust gas will be discharged through the through groove on the front side of the pressure relief box, thereby preventing the inside of the box from being deformed and damaged due to excessive pressure, and ensuring the safety of users; the limit block is fixed on the lower part of the inner wall of the pressure relief box. Under normal circumstances, the limit block will stop the pressure relief plate above the through grooves on the left side of the box and the right side of the inner wall of the pressure relief box to prevent the pressure relief plate from blocking the through grooves and causing excess exhaust gas to be unable to be discharged smoothly. The pressure regulating assembly is arranged inside the pressure relief box.

[0007] According to the above technical scheme, the pressure regulating assembly includes a push plate, a bolt and a limit block 2. Before use, the internal pressure of the box can be adjusted by the pressure regulating assembly. The middle part of the bolt is threadedly connected to the top of the pressure relief box. The bolt is manually tightened, and the top surface of the push plate is rotatably installed at the bottom of the bolt. The side of the push plate is slidably installed on the inner wall of the pressure relief box. The bolt pushes or pulls the push plate. A spring is arranged between the push plate and the pressure relief plate. The push plate squeezes or pulls the spring, so that the pressure on the pressure relief plate becomes larger or smaller. In this way, the purpose of controlling the size of the pressure relief pressure by controlling the tightening of the bolt can be achieved; the limit block 2 is fixed in the middle of the inner wall of the pressure relief box, and the push plate is limited by the limit block 2 to prevent the push plate from being pressed too deep and causing the spring to contract too strongly, thereby preventing the pressure relief plate from being unable to rise smoothly due to excessive pressure regulation.

The fan is fixed at the top of the inner wall of the box, the spray pipe is fixed at the top of the box, and the spray head is rotatably installed at the bottom of the spray pipe. When the coking waste gas enters the box, atomized water vapor is injected through the spray pipe and then sprayed out by the spray head to perform dust reduction treatment on the particulate matter in the coking waste gas. The fan is started, and the fan drives the water vapor to diffuse, so that the water vapor can more completely contact and combine with the gas inside the box, so that the dust reduction effect is better. The rotating component is arranged inside the box.

[0009] According to the above technical solution, the rotating assembly includes an eccentric plate, a square frame, a connecting rod, a friction block, and a round block. The eccentric plate is fixed to the bottom of the fan, and the fan drives the eccentric plate to rotate. The inner wall of the square frame is slidably mounted on the outer wall of the eccentric plate, and the eccentric plate drives the square frame to swing left and right. The connecting rod is fixed to the outer walls on the left and right sides of the square frame, and the connecting rod is slidably mounted on the top inner wall of the box body through a base. The square frame drives the connecting rod to swing left and right. The friction block is fixed to the middle of the connecting rod, and the connecting rod drives the friction block to swing left and right. The round block is fixed to the bottom of the spray head, and the round block is located on the movement track of the friction block. The friction block makes the round block rotate circularly through friction, and the round block drives the spray head to rotate. The rotation of the spray head enables the atomized water vapor to be sprayed in all directions, so that the atomized water vapor and the coking waste gas are better combined, further improving the dust reduction effect.

The two bottom grooves are fixed to the bottom inner wall of the box body, and the two sliding grooves are respectively slidably mounted inside the two bottom grooves. The activated carbon plate is fixed between the two sliding grooves. The scraping assembly is arranged on the outer wall of the activated carbon plate. By setting the activated carbon plate, impurities in the coking gas are adsorbed and removed. At the same time, when the activated carbon plate needs to be replaced, the activated carbon plate is slid out of the box body along the bottom groove, so that the purpose of convenient installation and disassembly of the activated carbon plate can be achieved, enabling the staff to replace the activated carbon plate more conveniently and saving the pre-preparation time for waste gas treatment.

[0011] According to the above technical solution, the scraping assembly includes a support rod, a scraper, and a collection bin.

When it is necessary to open or close the air inlet pipe of the box body, the switch is turned. The valve plate 1 is slidably mounted on the inner wall of the valve housing, and the switch pushes or pulls the valve plate 1 to move inside the valve housing. When the valve plate 1 blocks the air inlet of the valve housing, the air inlet is blocked. When the valve plate 1 leaves the air inlet of the valve housing, the coking waste gas can be smoothly injected, so as to achieve the purpose of freely injecting or disconnecting the air inlet.

One end of the special-shaped rod is slidably installed on the inner wall of the pressure relief box. The special-shaped rod is located on the movement track of the pressure relief plate. When the air pressure inside the box body is too high, the pressure relief plate is lifted, and the pressure relief plate pushes the special-shaped rod to rise. One end of the locking block near the back is hinged to the other end of the special-shaped rod, and the special-shaped rod pushes the locking block to rotate. The middle of the locking block is rotatably installed on the inner wall of the valve housing.

After the coking waste gas enters the box body 1, atomized water vapor is injected through the spray pipe 32 and then ejected by the spray head 33 to perform dust reduction treatment on the particulate matter in the coking waste gas. When the fan 31 is started, the fan 31 drives the diffusion of the water vapor, enabling the water vapor to come into contact and combine more completely with the gas inside the box body 1, resulting in a better dust reduction effect. The rotating assembly 34 is arranged inside the box body 1.

[0024] When in use, after the exhaust gas is injected into the box body 1, when the air pressure inside the box body 1 is too high, the excess gas will be discharged through the through slots opened on the left side of the box body 1 and the right side of the inner wall of the pressure relief box 21. The pressure difference between the inside and outside of the box body 1 causes the pressure relief plate 22 to rise under the action of pressure. When the pressure relief plate 22 passes over the through slot opened on the front side of the pressure relief box 21, the excess exhaust gas will be discharged through the through slot on the front side of the pressure relief box 21, thereby preventing the inside of the box body 1 from being deformed and damaged due to excessive pressure, thereby ensuring the safety of the users. At the same time, the limit block 23 will, under normal circumstances, stop the pressure relief plate 22 above the through slots on the left side of the box body 1 and the right side of the inner wall of the pressure relief box 21, preventing the pressure relief plate 22 from The through slot is blocked, so that the excess exhaust gas cannot be discharged smoothly; before use, the internal pressure of the box body 1 can be adjusted by the pressure regulating component 24, and the bolt 242 is manually turned.
