Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing environmental protection equipment, in particular to a plastic processing tail gas purification device. Background Art

[0002] Plastic processing will produce organic waste gas containing dust particles, non-methane total hydrocarbons and other harmful substances. This type of waste gas not only has a pungent odor but is also slightly toxic. Direct emission will cause great harm to human health and cause serious pollution to the environment. Therefore, it is necessary to use activated carbon adsorption, combustion, photocatalytic oxidation, plasma, UV photolysis, etc. for purification.

[0003] When using activated carbon adsorption to purify the tail gas of plastic processing, an activated carbon adsorption box can be used, in which the activated carbon adopts a square block structure, and the tail gas passes through one side of the activated carbon from the air inlet. Since the pollutants in the tail gas are the most at this time, the higher the adsorption degree of this side of the activated carbon block, after a long time, it will cause the adsorption degree of the entire activated carbon block to be uneven, and the area with a higher adsorption degree is more likely to cause secondary pollution to the tail gas. In order to avoid this problem, it is necessary to increase the replacement or cleaning frequency of the activated carbon block, resulting in an increase in workload. To this end, the utility model proposes a plastic processing tail gas purification device that can make activated carbon evenly adsorbed. Utility Model Content

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-5 As shown, the utility model provides a plastic processing tail gas purification device, which includes a purification box 1 and an activated carbon block 2 arranged in the purification box 1. Inlet and outlet nozzles 11 are arranged at both ends of the purification box 1.

[0031] In this embodiment, the exhaust gas purification device includes an activated carbon block rotating mechanism 3 that drives the activated carbon block 2 to rotate horizontally to switch the contact surface with the exhaust gas. The activated carbon block rotating mechanism 3 includes an activated carbon block fixing component 31 for fixing the activated carbon block 2 and rotatably connected to the purification box 1, and a motor 32 for driving the activated carbon block fixing component 31 to rotate;

[0032] The activated carbon block fixing assembly 31 includes a bottom plate 312 for supporting the activated carbon block 2 and a top plate 311 located on the top of the activated carbon block 2 and vertically slidably sleeved with the bottom plate 312. A pair of front edge clamping arms 3112 that engage with two of the ridges of the activated carbon block 2 are fixedly connected to the front lower surface of the top plate 311, a pair of rear edge clamping arms 3121 that engage with the remaining two ridges of the activated carbon block 2 are fixedly connected to the rear upper surface of the bottom plate 312, and a first guide column 3111 that is movably sleeved with the corresponding rear edge clamping arms 3121 is fixedly connected to the rear lower surface of the top plate 311. In addition, the front edge clamping arms 3112 are fixedly connected to the bottom surface of the bottom plate 312. Figure 3 As shown, it is shorter than the rear edge clamp arm 3121 so that Figure 4 As shown, the activated carbon block 2 can be taken and placed horizontally from the bottom plate 312;

[0033] A connecting shaft 3113 is fixedly connected to the upper surface of the top plate 311 , and the connecting shaft 3113 is coaxially fixed with the output shaft of the motor 32 .

[0034] In this embodiment, the exhaust gas purification device further includes a box cover 4, and the four corners of the lower surface of the box cover 4 are fixedly connected with second guide pillars 41, and the second guide pillars 41 are movably connected with the purification box 1. The box cover 4 is fixedly connected to the top plate 311 by bolts and is fixedly connected to the purification box 1 by bolts. The motor 32 is fixedly installed on the upper surface of the box cover 4 and the output shaft movably penetrates the box cover 4 and is connected to the connecting shaft 3113.

[0035] Furthermore, the exhaust gas purification device further comprises a support arm 5, one end of which is rotatably connected to the rear edge clamp arm 3121 via a rotating shaft. Figure 2 and Figure 4 As shown, when the top plate 311 moves upward with the box cover 4, the support arm 5 can be rotated upward 180° to support the top plate 311, and then the activated carbon block 2 can be placed on the bottom plate 312 or removed from it. After the activated carbon block 2 is replaced, the support arm 5 is rotated back to its original position, allowing the top plate 311 and the box cover 4 to move down again, and finally the box cover 4 can be fixed to the top of the purification box 1 by bolts or other connection methods.

[0036] The working principle of this embodiment is as follows: the tail gas generated by plastic processing enters the purification box 1 through one of the air inlet and outlet nozzles 11 of the purification box 1, and first contacts one of the surfaces of the activated carbon block 2. This surface first contacts the unpurified tail gas, and the degree of adsorption will be higher than other surfaces, which is easy to cause secondary pollution to the tail gas or insufficient purification in subsequent purification. In this embodiment, after a period of purification treatment, the motor 32 can drive the activated carbon block fixing component 31 to rotate, and then drive the activated carbon block 2 to rotate, and rotate the two sides with lower adsorption to the gas flow path, so that the gas can be uniformly adsorbed as a whole, thereby reducing the replacement and cleaning frequency of the activated carbon block 2.

[0037] In summary, through the design of the activated carbon block rotating mechanism 3, the activated carbon block 2 can be horizontally rotated to switch its contact surface with the exhaust gas, thereby achieving uniform adsorption of the exhaust gas by each surface, and reducing the replacement and cleaning frequency of the activated carbon block 2; by dividing the activated carbon block fixing assembly 31 into a top plate 311 and a bottom plate 312 that can be vertically relatively moved, and a vertically movable design of the box cover 4, and combined with the support of the support arm 5, it is convenient to replace the activated carbon block 2, the activated carbon block fixing assembly 31 and the activated carbon block 2 in the purification box 1.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
