[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1 and Figure 2A harmful gas treatment device for a factory includes a treatment box 1, a purification box 2, an adsorption mechanism 3, and a spray mechanism 4. The treatment box 1 is in the shape of a rectangular parallelepiped with a hollow interior and an open top, and a cover plate 11 is hingedly connected to the top of the treatment box 1 at the opening. A sealing ring (not shown in the figure) is fixed on the bottom surface of the cover plate 11 along its circumferential surface. The purification box 2 is arranged on one side of the treatment box 1. The purification box 2 is in the shape of a rectangular parallelepiped with a hollow interior. A connecting pipe 5 is fixed between the treatment box 1 and the purification box 2. The two ends of the connecting pipe 5 are respectively connected to the interior of the treatment box 1 and the interior of the purification box 2, and an air pump 51 is fixed on the connecting pipe 5. An air inlet pipe 12 is fixed on the side wall of the treatment box 1 away from the purification box 2. The air inlet pipe 12 is connected to the interior of the treatment box 1, and a gas detection alarm 13 is fixed on the air inlet pipe 12. An air outlet pipe 21 is fixed on the side wall of the purification box 2 away from the treatment box 1, and the air outlet pipe 21 is connected to the interior of the purification box 2. A drain pipe 22 is fixedly mounted on the side wall of the purification box 2, below the outlet pipe 21. A valve 221 is fixedly mounted on the drain pipe 22. An adsorption mechanism 3 is disposed within the treatment box 1 and is used for preliminary adsorption treatment of harmful gases. A spray mechanism 4 is disposed within the purification box 2 and is used for secondary treatment of harmful gases.

[0024] During use, when harmful gas is detected, the gas detection alarm 13 will first sound an alarm to warn the operator, and then start the air extraction pump 51. The harmful gas will enter the treatment box 1 through the air inlet pipe 12 and reach the adsorption mechanism 3, where it can be adsorbed and processed. The adsorbed gas can then enter the purification box 2 through the connecting pipe 5, and the spray mechanism 4 will be started to perform secondary treatment on the gas before it is finally discharged from the air outlet pipe 21. The harmful gas undergoes secondary treatment to reduce the harm it causes.

[0025] The gas detection alarm 13 is a non-essential component. When the gas detection alarm 13 is not provided, the air extraction pump 51 can be started manually or automatically at regular intervals to extract and purify the gas in the factory workshop.

[0026] Reference Figure 2 The adsorption mechanism 3 includes a first adsorption plate 31, a second adsorption plate 32, and a third adsorption plate 33. The first adsorption plate 31 is a solid waste-based activated carbon plate, the second adsorption plate 32 is an activated alumina plate, and the third adsorption plate 33 is a zeolite molecular sieve plate. The first adsorption plate 31, the second adsorption plate 32, and the third adsorption plate 33 are all arranged along the width direction of the processing box 1 and are evenly spaced along the length direction of the processing box 1. The three are arranged perpendicular to the bottom surface of the processing box 1 and are all clamped on the bottom surface of the processing box 1. An ultraviolet lamp 34 is also fixed between the three at the bottom end of the processing box 1.

[0027] During use, the gas enters from the air inlet pipe 12, and will be adsorbed by the first adsorption plate 31, the second adsorption plate 32, and the third adsorption plate 33 in sequence. At the same time, it will also be irradiated by the ultraviolet lamp 34, and finally the vacuum pump is started to enter the purification box 2 for subsequent operations. After using it for a period of time, the cover 11 can also be opened to take out the first adsorption plate 31, the second adsorption plate 32, and the third adsorption plate 33 for cleaning. Among them, the solid waste-based activated carbon plate not only realizes the recycling of waste gas resources, but also can show good adsorption performance in purifying harmful gases; the activated alumina plate is a porous, highly dispersed solid material with a large surface area, which can adsorb some organic gases; the zeolite molecular sieve plate is a crystalline silicate or aluminosilicate with uniform pore size, which can also adsorb harmful gases; the ultraviolet lamp 34 can emit short-wave ultraviolet rays, which can directly destroy the chemical bonds of harmful gases, causing the decomposition of harmful gas molecules.

[0028] Reference Figure 2 and Figure 3 The spray mechanism 4 comprises a spray assembly 41, a storage assembly 42, and a drive assembly 43. The spray assembly 41 includes a screw 411, a slider 412, a fixed plate 413, and a nozzle 414. The screw 411 is arranged along the length of the purification chamber 2 and is located at the top of the purification chamber 2. The end of the screw 411, facing away from the treatment chamber 1, passes through the side wall of the purification chamber 2 and is rotationally connected thereto. The other end is rotationally connected to the opposite side wall of the purification chamber 2. The drive assembly 43 drives the screw 411 to rotate. The threads at both ends of the screw 411 are in opposite directions. There are two sliders 412, each of which is threadedly connected to the screw 411 at opposite ends. Two first mounting plates 415 are fixed to the bottom surfaces of the two sliders 412. The two first mounting plates 415 are spaced apart along the width of the purification chamber 2, and a first rotation axis 416 is fixed between the two first mounting plates 415. The fixed plate 413 is arranged parallel to the bottom surface of the purification chamber 2 and is located below the screw 411. Two sets of second mounting plates 417 are fixed to the top surface of the fixed plate 413. Each set of second mounting plates 417 contains two second mounting plates 417, which are spaced apart along the width of the purification box 2. A second rotation axis 418 is fixed between each set of two second mounting plates 417. A connecting rod 419 is provided between the first rotation axis 416 and the second rotation axis 418 located on the same side, and the ends of the connecting rod 419 are rotatably connected to the first rotation axis 416 and the second rotation axis 418, respectively. The interior of the fixed plate 413 is hollow, and there are multiple nozzles 414, which are evenly fixed to the bottom surface of the fixed plate 413 and communicate with the interior of the fixed plate 413.

[0029] Reference Figure 1 and Figure 2The storage assembly 42 includes a liquid storage tank 421 and a liquid storage pipe 422. Liquid storage tank 421 is fixed to the outer wall of the purification tank 2 near the treatment tank 1 and is used to store liquid that can purify harmful gases. A water pump (not shown) is installed within the liquid storage tank 421. Liquid storage pipe 422 is a flexible hose. One end of the liquid storage pipe 422 is fixedly connected to the liquid storage tank 421, and the other end passes through the side wall of the purification tank 2 and is fixedly connected to the fixed plate 413. Liquid storage pipe 422 communicates with the interiors of the liquid storage tank 421 and the fixed plate 413, respectively.

[0030] Starting the drive assembly 43 can drive the screw 411 to rotate, which can lengthen or shorten the distance between the two sliders 412, so that the fixed plate 413 moves along the height direction of the purification box 2 under the action of the connecting rod 419. The lower end of the vertical stroke of the fixed plate 413 is located above the interface between the connecting pipe 5 and the purification box 2, which makes it easier to mix the liquid and gas and purify the gas. Finally, the gas is discharged from the outlet pipe 21. After opening the valve 221, the liquid is discharged from the drain pipe 22.

[0031] Reference Figure 3 The drive assembly 43 includes a motor 431, a first pulley 432, and a second pulley 433. The motor 431 is fixed to the top surface of the cleanroom 2, near the end of the screw 411 extending out of the cleanroom 2. The output shaft of the motor 431 is parallel to the screw 411. The first pulley 432 is mounted on the output shaft of the motor 431 and is fixedly connected thereto. The second pulley 433 is mounted on the end of the screw 411 extending out of the cleanroom 2 and is fixedly connected thereto. A belt 434 is mounted on the first and second pulleys 432, 433.

[0032] Start the motor 431, and the output shaft of the motor 431 can drive the first pulley 432 to rotate. Since the first pulley 432 and the second pulley 433 are connected by the belt 434, the second pulley 433 can also be driven to rotate, thereby causing the screw 411 to rotate, providing power for the spray assembly 41.

[0033] The operating principle of the present invention is as follows: when harmful gas approaches the treatment box 1, the gas detection alarm 13 will sound to warn the operator, and the vacuum pump 51 will be activated. The harmful gas will enter the treatment box 1 through the air inlet pipe 12 for preliminary treatment. After being adsorbed by the adsorption mechanism 3 and irradiated by the ultraviolet lamp 34, the gas that has undergone preliminary treatment will enter the purification box 2 for secondary treatment. The spray mechanism 4 will be activated to fully mix the liquid and gas for purification, and finally the gas will be discharged from the outlet pipe 21. By performing secondary purification treatment on the gas, the harmfulness of the gas is further reduced.

[0034] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
