[0035] When the waste gas is injected into the box 1, if the pressure in the box 1 is too large, the excess gas will be discharged through the through grooves formed on the left side of the box 1 and the right inner wall of the pressure relief box 21. The pressure difference between the inside and outside of the box 1 causes the pressure relief plate 22 to be lifted. When the pressure relief plate 22 passes through the through groove formed on the front of the pressure relief box 21, the excess waste gas will be discharged through the through groove on the front of the pressure relief box 21, thereby preventing the box 1 from being damaged due to excessive pressure and ensuring the safety of the user.

Example 2

[0037] Please refer to Figures 1-7 Based on the basis of example 1, the adsorption device 4 and the valve closing device 5 are further included in this embodiment.

[0038] The adsorption device 4 comprises an activated carbon plate 41, two sliding grooves 42, two bottom grooves 43 and a scraping assembly 44. The two bottom grooves 43 are fixed to the bottom of the inner wall of the box body 1, the two sliding grooves 42 are slidingly installed in the two bottom grooves 43 respectively, the activated carbon plate 41 is fixed between the two sliding grooves 42, and the scraping assembly 44 is arranged on the outer wall of the activated carbon plate 41. The impurities in the coking gas are adsorbed and removed through the arrangement of the activated carbon plate 41. When the activated carbon plate 41 needs to be replaced, the activated carbon plate 41 is slid out of the box body 1 along the bottom groove 43, so that the activated carbon plate 41 can be conveniently installed and removed, the staff can replace the activated carbon plate 41 more conveniently, and the preparation time of waste gas treatment is saved.

[0039] The scraping assembly 44 comprises a supporting rod 441, a scraper 442 and a collection bin 443. The top end of the supporting rod 441 is hinged to the outer wall of the connecting rod 343. After the treatment in the box body 1 starts, the connecting rod 343 drives the supporting rod 441 to swing left and right. The scraper 442 is hinged to the bottom end of the supporting rod 441, and the supporting rod 441 drives the scraper 442 to slide up and down. The scraper 442 is slidingly installed on the outer wall of the activated carbon plate 41 and slides on the surface of the activated carbon plate 41. The collection bin 443 is fixed to the inner wall bottom surface of the box body 1, so that the coking impurities adsorbed on the surface of the activated carbon plate 41 are scraped off and fall into the collection bin 443 for subsequent cleaning, thereby prolonging the service life of the activated carbon plate 41 and preventing the decline of the adsorption impurity effect of the activated carbon plate 41.

[0040] The valve closing device 5 comprises a valve shell 51, a switch 52, a valve plate one 53 and a locking assembly 54. The valve shell 51 is fixed to the left air inlet of the box body 1. The switch 52 is threadedly connected to the top of the valve shell 51. When it is necessary to open or close the air inlet pipeline of the box body 1, the switch 52 is twisted. The valve plate one 53 is slidingly installed in the inner wall of the valve shell 51. The switch 52 drives or pulls the valve plate one 53 to move in the valve shell 51. When the valve plate one 53 blocks the air inlet of the valve shell 51, the air inlet is blocked. When the valve plate one 53 leaves the air inlet of the valve shell 51, the coking waste gas can be smoothly injected, thereby achieving the purpose of free injection or disconnection of the air inlet. The locking assembly 54 is arranged in the valve shell 51.

[0041] The locking assembly 54 comprises a special-shaped rod 541, a locking block 542, an elastic rod 543 and a valve plate two 544. One end of the special-shaped rod 541 is slidingly installed on the inner wall of the pressure relief box 21, and the special-shaped rod 541 is located on the movement track of the pressure relief plate 22. When the internal pressure of the box body 1 is too large, the pressure relief plate 22 is lifted, and the pressure relief plate 22 pushes the special-shaped rod 541 to rise. One end of the locking block 542 close to the back is hinged to the other end of the special-shaped rod 541. The special-shaped rod 541 pushes the locking block 542 to rotate.

The protrusion of the valve plate two 544 is no longer blocked and limited by the locking block 542. The valve plate two 544 is slidingly installed on the inner wall of the valve shell 51. A spring is arranged between the valve plate two 544 and the bottom of the valve shell 51. The valve plate two 544 falls back under the action of the spring force, thereby achieving the purpose of instantaneously blocking the air inlet of the valve shell 51 when the internal pressure of the box body 1 is too large, and further preventing the continuous injection of coking waste gas from causing the deformation and damage of the box body 1 due to the excessive internal pressure.

[0042] When in use, the impurities in the coking gas are adsorbed and removed by the setting of the activated carbon plate 41. When the activated carbon plate 41 needs to be replaced, the activated carbon plate 41 is slid out of the box body 1 along the bottom groove 43, so that the activated carbon plate 41 can be conveniently installed and removed, and the staff can more conveniently replace the activated carbon plate 41, thereby saving the preparation time of the waste gas treatment in the early stage; after the treatment in the box body 1 starts, the connecting rod 343 drives the supporting rod 441 to swing left and right, the supporting rod 441 pushes the scraper 442 to slide up and down, and the scraper 442 slides on the surface of the activated carbon plate 41, so that the coking impurities adsorbed on the surface of the activated carbon plate 41 are scraped off and fall into the collection bin 443 for subsequent cleaning, thereby achieving the purposes of prolonging the service life of the activated carbon plate 41 and preventing the effect of adsorbing impurities of the activated carbon plate 41 from being reduced.

[0043] When it is necessary to open or close the air inlet pipe of the box body 1, the switch 52 is twisted, the switch 52 pushes or pulls the valve plate one 53 to move in the valve shell 51. When the valve plate one 53 blocks the air inlet of the valve shell 51, the air inlet is blocked. When the valve plate one 53 leaves the air inlet of the valve shell 51, the coking waste gas can be smoothly injected, thereby achieving the purpose of free injection or disconnection of the air inlet; when the internal pressure of the box body 1 is too large, the pressure relief plate 22 is lifted, the pressure relief plate 22 pushes the special-shaped rod 541 to rise, the special-shaped rod 541 pushes the locking block 542 to rotate, the elastic rod 543 is retracted, the protrusion of the valve plate two 544 is no longer blocked and limited by the locking block 542, and the valve plate two 544 falls back under the action of the spring force, thereby achieving the purpose of instantaneously blocking the air inlet of the valve shell 51 when the internal pressure of the box body 1 is too large, and further preventing the continuous injection of coking waste gas from causing the deformation and damage of the box body 1 due to the excessive internal pressure.
