Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas dust removal and purification device. Background Art

[0002] Waste gas purification mainly refers to the process of treating industrial waste gas generated in industrial sites, such as dust particles, smoke and soot, odorous gases, toxic and harmful gases, etc. If these waste gases are directly discharged into the atmosphere, they will have a harmful effect on the environment and human health. Therefore, purification measures need to be taken before they are discharged into the atmosphere to ensure that they meet the waste gas emission standards.

[0003] After a car has undergone paint-related repairs, it needs to be repainted. At present, the paint rooms of auto repair shops and 4S shops mainly filter paint exhaust gas by adsorption, that is, adsorption through adsorption materials, and other purification methods are also used simultaneously. The current filtration mostly uses a whole filtration device, which needs to be installed and routed separately, so there are certain requirements for the installation space and location.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-4 , an exhaust gas dust removal and purification device comprises a butt joint 1, the two ends of the butt joint 1 are connected and communicated with the exhaust gas conveying pipe 7 arranged at the corresponding position by bolts, an opening 13 with a half circumference is preset on the butt joint 1, and a pipe cover plate 2 with a half circumference of the butt joint 1 is arranged at the position of the opening 13, the pipe cover plate 2 and the corresponding side position of the opening 13 are hinged and fixed to each other through a hinge 3, and a buckle 4 that cooperates with each other is bolted between the pipe cover plate 2 on the other side and the butt joint 1 at the position of the opening 13, at least three arc pads 5 with a half arc are welded and installed on the inner wall of the butt joint 1, and inverted L-shaped side plates 14 are welded and installed on the left and right sides of the arc pad plate 5, and a "convex"-shaped limiting cavity 17 is formed between the side plates 14 on both sides and the arc pad plate 5, and a number of filter material frames 8 corresponding to the number of arc pad plates 5 are placed in the butt joint 1, and the outer wall of the filter material frame 8 abuts against the arc pad plate 5 in the limiting cavity 17 to form a fixed placement, and the filter material frame 8 is filled with a molecular sieve 9.

[0027] When in use, cut a section from the existing exhaust gas conveying pipe 7, and then install the connecting pipe 1. After installation, place the filter material frame 8 filled with molecular sieve 9, and finally use the hinge 3 to close the pipe cover 2, and then buckle 4. When the paint exhaust gas is discharged through the existing exhaust gas conveying pipe 7, when the exhaust gas passes through the connecting pipe 1, the molecular sieve 9 uses its own microporous characteristics similar to activated carbon to adsorb volatile organic compounds, particulate matter, paint mist and other harmful substances that may exist in the paint exhaust gas such as benzene, toluene, and xylene, thereby achieving the purpose of purifying the exhaust gas. Of course, the molecular sieve 9 can also be replaced by other materials that adsorb through microporous characteristics, such as activated carbon. The exhaust gas discharged into the environment can be purified through material adsorption, thereby reducing pollution to the environment.

[0028] In this embodiment, an arc pad plate 2 6 is welded and installed at the position of the arc pad plate 1 5 on the inner wall of the pipe cover plate 2 . The cross section of the arc pad plate 2 6 is arranged in a ︹-shaped structure, and the filter material frame 8 reaches the middle limit position of the arc pad plate 2 6 .

[0029] After the pipe cover 2 is closed, the arc pad 2 6 and the arc pad 1 5 jointly limit and fix the filter material frame 8, which on the one hand provides a fixing effect, and on the other hand reduces the gap between the filter material frame 8 and the docking pipe 1 and the pipe cover 2, thereby reducing the amount of untreated exhaust gas escaping through the gap.

[0030] In this embodiment, a plurality of guide rollers 15 are provided at equal intervals on the inner side of the limiting cavity 17, and roller shafts 16 are welded and installed at both ends of the guide rollers 15. The roller shafts 16 are inserted into the side plates 14 at the corresponding positions to form plug-in fixation, and the outer wall of the filter material frame 8 abuts against the guide rollers 15 to form a rotatable and movable fixation, and the side walls of the filter material frame 8 simultaneously abut against the side plates 14 at the mouth of the limiting cavity 17.

[0031] After the filter material frame 8 is placed, since the guide roller 15 is fixed on the side plate 14 by the insertion of the roller shaft 16, the filter material frame 8 can be rotated. The rotation of the filter material frame 8 can be adjusted according to the installation situation during installation to facilitate installation. At the same time, it can be rotated to check the internal molecular sieve 9 and determine whether it needs to be replaced.

[0032] In this embodiment, two pipe buckles 10 are installed on the exhaust gas conveying pipes 7 at both ends of the butt-joint pipe 1 by bolts, and at least three protrusions 11 are integrally formed and installed on the two pipe buckles 10 at the bottom, and a reinforcing rod 12 is passed between the corresponding protrusions 11 at both ends of the butt-joint pipe 1.

[0033] Since the filter material frame 8 and the molecular sieve 9 are added to the butt joint pipe 1, the overall weight is much greater than the weight of the exhaust gas conveying pipe 7 of the same length. If it is simply fixed by bolts, it is easy to cause a single force on the fixed position and deformation due to long-term pulling force over a long period of time. Through the cooperation of the reinforcing rod 12 and the pipe buckle 10, the force points of the butt joint pipe 1 and the exhaust gas conveying pipe 7 are increased, thereby distributing the force, delaying deformation, and ensuring a longer service life.
