Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas treatment equipment, and more specifically relates to an integrated small VOCs treatment device. Background Technology

[0002] Currently, most small-scale VOCs treatment methods employ adsorption, which purifies waste gas through the physical adsorption of adsorbent materials. However, due to the limited adsorption capacity of small-scale treatment devices, it is necessary to frequently replace the adsorbent material, and the replacement process is quite cumbersome. It requires first removing the sealing door on the replacement port, then disassembling and installing the support containing the adsorbent material inside, removing the support from the replacement port, replacing the adsorbent material from the outside, and finally reinstalling the support inside the device and sealing it again with the sealing door (as disclosed in the utility model patent with publication number CN216630237U, which describes an activated carbon adsorption box for adsorbing VOCs). The entire process is inefficient, and the frequent replacements greatly increase the labor intensity of workers. Furthermore, the device needs to be stopped during replacement, which affects the waste gas treatment efficiency. Utility Model Content

[0020] Reference Figures 1 to 5 The present invention will be further described below.

[0021] An integrated small VOCs treatment device includes an adsorption box 1, on which several adsorption supports 2 are provided. The two ends of the adsorption supports 2 are located outside the adsorption box 1. The adsorption supports 2 are slidably connected to the adsorption box 1, and a positioning mechanism is provided between the adsorption supports 2 and the adsorption box 1. Several transparent placement slots 3 are provided on the adsorption supports 2, and adsorption plates 4 are provided in the placement slots 3. An air sealing device corresponding to the adsorption supports 2 is provided on the outer surface of the adsorption box 1.

[0022] Specifically, the placement slots 3 on the adsorption support 2 are arranged sequentially along the length of the adsorption support 2.

[0023] like Figure 3 As shown, specifically, a placement plate is provided on the side wall of the placement groove 3, and the edge of the adsorption plate 4 rests on the placement plate.

[0024] like Figures 1 to 3As shown in the preferred embodiment, the adsorption box 1 has openings 5 ​​on opposite sides, the adsorption support 2 passes through the openings 5, and the air sealing device includes an air sealing block 6 located on the opening 5. The air sealing block 6 has an air sealing hole 7 corresponding to the opening 5. The adsorption support 2 passes through the air sealing hole 7, and an air sealing channel 8 is formed between the surface of the adsorption support 2 and the inner wall of the air sealing hole 7. The air sealing block 6 has a blowing chamber 9 and a suction chamber 10, and both the blowing chamber 9 and the suction chamber 10 are connected to the air sealing hole 7. The blowing chamber 9 is located on the air sealing block 6 away from the adsorption box 1, and the suction chamber 10 is located on the air sealing block 6 close to the adsorption box 1. The air sealing block 6 is connected to a blowing pipe 11 and a suction pipe 12.

[0025] Specifically, air is blown into the air-sealing channel 8 through the blowing chamber 9. After being blocked by the adsorption support 2 at the air inlet of the blowing chamber 9 connecting to the air-sealing channel 8, the gas flows to the outside and inside of the air-sealing channel 8 respectively. The suction chamber 10 then draws in the gas located on both sides of the air inlet of the suction chamber 10 in the air-sealing channel 8, thereby forming an air seal and preventing the waste gas in the adsorption box 1 from leaking. At the same time, it will not affect the sliding of the adsorption support 2.

[0026] Specifically, the gas being blown can be air or gas that has already undergone exhaust treatment and is ready for discharge.

[0027] Specifically, the intake pipe 12 retransmits the gas to the exhaust gas delivery pipe connected to the adsorption box 1.

[0028] like Figure 2 As shown in this example, preferably, the blowing pipe 11 and the suction pipe 12 are both wrapped around the outside of the air seal block 6 and are connected to the blowing chamber 9 and the suction chamber 10 respectively through several pipes.

[0029] like Figure 2 As shown, in this example, preferably, several blowing pipes 11 are connected to the same air supply pipe 13, and several suction pipes 12 are connected to the same exhaust pipe 14.

[0030] like Figure 4 As shown in this example, preferably, the adsorption box 1 has support plates 15 on both sides, the adsorption bracket 2 is slidably connected to the support plates 15, and the positioning mechanism is located on the support plates 15.

[0031] like Figure 3 As shown, in this preferred embodiment, the positioning mechanism includes a groove 16 located on the support plate 15, a spring 17 is provided in the groove 16, a top bead 18 is provided at the top of the groove 16, the spring 17 is connected to the top bead 18, and a positioning groove 19 corresponding to the top bead 18 is provided at the bottom of the adsorption bracket 2.

[0032] Specifically, when the adsorption bracket 2 is pushed so that the positioning groove 19 at its bottom engages with the top bead 18, the position of the adsorption bracket 2 can be positioned by the top bead 18, so that the adsorption plate 4 is exactly in the adsorption position inside the adsorption box 1, and at the same time the top bead 18 prevents the adsorption bracket 2 from sliding easily.

[0033] Specifically, the positioning mechanism is located on both sides of the adsorption bracket 2.

[0034] In this preferred embodiment, the support plate 15 is provided with a guide rail, and the adsorption bracket 2 is provided with a guide groove corresponding to the guide rail, so as to realize the linear movement of the adsorption bracket 2.

[0035] like Figures 1 to 4 As shown, the adsorption bracket 2 passes directly through the adsorption box 1, and the adsorption plate 4 on the adsorption bracket 2 located inside the adsorption box 1 adsorbs the waste gas. When the adsorption plate 4 needs to be replaced, the adsorption bracket 2 is pushed directly on one side of the adsorption bracket 2 so that the adsorption plate 4 located outside the adsorption box 1 enters the adsorption box 1, thereby realizing the rapid replacement of the adsorption plate 4, and the adsorption box 1 does not need to stop running, which is highly efficient.

[0036] Specifically, when the old adsorption plate 4 begins to move out of the adsorption box 1, the new adsorption plate 4 begins to enter the adsorption box 1.

[0037] Specifically, the adsorption support 2 is provided with at least two placement slots 3 for adsorption plates 4 so as to achieve alternating use.

[0038] like Figure 5 As shown, specifically, the adsorption support 2 located outside the adsorption box 1 is provided with a sealing layer 20 corresponding to the adsorption plate 4. When the adsorption plate 4 needs to be replaced, the sealing cover or sealing film on the adsorption plate 4 to be pushed into the adsorption box 1 is removed, and the sealing layer 20 protects the new adsorption plate 4 from air pollution.

[0039] Specifically, since the adsorption plate 4 is a dense porous plate, when removing the sealing layer 20, the sealing layer 20 needs to be gradually opened as the new adsorption plate 4 is inserted. That is, the part of the new adsorption plate 4 that is still outside the adsorption box 1 will still be covered and sealed by the sealing layer 20, so as to reduce the exchange of gas inside and outside the adsorption box 1 through the holes in the adsorption plate 4 when replacing it.

[0040] Specifically, the sealing layer 20 can be a sealing film or a sealing cover. If a sealing film is used, two sealing films are respectively applied to the upper and lower sides of the placement groove 3. When pushing in the adsorption bracket 2, the sealing film is torn open while pushing in. If a sealing cover is used, two cover plates are respectively located on the upper and lower sides of the placement groove 3 and are slidably connected to the adsorption bracket 2. When pushing in the adsorption bracket 2, the sealing cover is slid open while pushing in.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
