[0002] VOCs (volatile organic compounds) refer to various organic compounds with boiling points ranging from 50°C to 260°C at room temperature. VOCs emitted by industrial enterprises will have varying degrees of impact and harm to human health, animals, plants and the environment. In VOCs treatment, activated carbon adsorption is often used to purify gaseous pollutants. After proper treatment, the adsorbed VOCs release carbon dioxide and water vapor to achieve efficient collection and treatment.

[0003] In existing VOCs collection devices, when using activated carbon for adsorption, the activated carbon is usually washed with water to ensure its adsorption capacity and purification effect to meet the collection and treatment needs of VOCs.

[0004] For example, in the Chinese utility model patent with publication number (CN213132547U), a VOCs activated carbon adsorption regeneration treatment device is disclosed, which belongs to the field of activated carbon regeneration treatment technology. In view of the problem that the traditional activated carbon regeneration and utilization is complicated, and the activated carbon usually needs to be taken out from the filter adsorption device for cleaning, which is inconvenient to use, the following scheme is proposed, which includes a filter adsorption box, the top of which is connected to an air inlet pipe and an air outlet pipe, a support plate is fixedly installed in the filter adsorption box, an adsorption box is placed on the top of the support plate, the adsorption box is movably connected to the filter adsorption box, and a drying structure is provided on one side of the filter adsorption box. Thereby, the activity of the activated carbon adsorption particles can be improved without disassembling the activated carbon adsorption particles, which is convenient to use.

[0005] However, this design still has some defects. For example, it requires additional use of clean water and drying structure to clean the activated carbon, which makes the cost of VOCs collection and treatment too high and is not conducive to popularization and use. Utility Model Content

[0009] The VOCs collection device of the utility model recovers the carbon dioxide, water and heat generated after the treatment in the treatment chamber, so that the carbon dioxide, water and heat can flow back to the adsorption chamber and efficiently clean the activated carbon, wherein both the water and the carbon dioxide have part of the heat attached to them, the water can clean the activated carbon through the recovery pipe, and the carbon dioxide can dry the activated carbon through the drying pipe, thereby ensuring the activity of the activated carbon adsorption particles and maintaining the dryness of the activated carbon, thereby achieving the effect of energy saving and cost reduction, which is conducive to promotion and application, and in addition, the VOCs can be heated before being treated, which is conducive to improving the VOCs treatment efficiency.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The VOCs collection device according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 3 As shown, the VOCs collection device according to the embodiment of the utility model may include a VOCs collection chamber 10 , an adsorption chamber 20 , a drying tube 40 and a processing chamber 30 .

[0024] Among them, a first fan 50 is installed on the VOCs collection chamber 10, and an inlet pipe 21 and an outlet pipe 22 are arranged on the adsorption chamber 20, wherein the inlet pipe 21 is connected to the VOCs collection chamber 10, and the outlet pipe 22 is connected to the treatment chamber 30, and the activated carbon 23 inside the adsorption chamber 20 is located between the inlet pipe 21 and the outlet pipe 22.

[0025] One end of the drying tube 40 is connected to the processing chamber 30 , and the other end of the drying tube 40 passes through the adsorption chamber 20 and is installed with a second fan 60 , wherein the drying tube 40 passes through the inside of the activated carbon 23 .

[0026] It should be noted that the drying tube 40 described in this embodiment passes through the inside of the activated carbon 23. The setting of the drying tube 40 does not affect the adsorption function of the activated carbon 23 on the VOCs gas in the adsorption chamber 20, and the drying tube 40 can efficiently dry the activated carbon 23 and heat the VOCs gas at the same time, which is beneficial to the subsequent treatment efficiency of the VOCs gas in the treatment chamber 30.

[0027] A processing element is disposed in the processing chamber 30 , and the bottom of the processing chamber 30 is connected to the adsorption chamber 20 below through a recovery pipe 31 , wherein a water outlet valve is disposed at the bottom of the adsorption chamber 20 , and a valve 70 is disposed on the recovery pipe 31 .

[0028] It should be noted that the processing element described in this embodiment can process the VOCs gas entering the processing chamber 30 and convert the VOCs gas into carbon dioxide, water and heat.

[0029] It should be noted that the treatment chamber 30 described in this embodiment can be installed by a support frame or the like (not shown in the figure) so that the height of the treatment chamber 30 is greater than the height of the adsorption chamber 20, so that after the valve 70 is opened, without being subjected to external force, the water discharged from the bottom of the treatment chamber 30 can flow smoothly into the adsorption chamber 20 through the recovery pipe 31 and wash the activated carbon 23 with water.

[0030] Specifically, in the actual process of collecting and treating VOCs gas, the relevant personnel first start the first fan 50. After the first fan 50 is started, the VOCs gas in the environment is sucked into the VOCs collection chamber 10. The VOCs gas then enters the adsorption chamber 20 from the inlet pipe 21, and after being adsorbed by the activated carbon 23, it enters the treatment chamber 30 from the outlet pipe 22 for treatment.

[0031] After the treatment chamber 30 processes the incoming VOCs gas through the treatment element, the VOCs gas forms carbon dioxide, water and heat, among which some heat is attached to the water and carbon dioxide. After the valve 70 is opened, in the absence of external force, the water discharged from the bottom of the treatment chamber 30 can flow smoothly into the adsorption chamber 20 through the recovery pipe 31 and wash the activated carbon 23 with water. The water after washing the activated carbon 23 can be discharged through the water outlet valve at the bottom of the adsorption chamber 20.

[0032] Driven by the second fan 60, carbon dioxide can be discharged from the treatment chamber 30 through the drying tube 40. During the transportation of carbon dioxide by the drying tube 40, the carbon dioxide passes through the activated carbon 23 and dries it, thereby ensuring the activity of the adsorbed particles of the activated carbon 23 and maintaining the dryness of the activated carbon 23, thereby achieving energy saving and cost reduction effects, which is conducive to promotion and application.

[0033] In one embodiment of the present invention, Figure 2 As shown, the adsorption chamber 20 is vertically arranged, the inlet pipe 21 and the outlet pipe 22 are respectively arranged on the left and right symmetrical sides of the activated carbon 23, and the outlet end of the recovery pipe 31 passes through the top of the adsorption chamber 20 and is located above the activated carbon 23. It can be understood that such a design helps the recovery pipe 31 to rinse the activated carbon 23 below.

[0034] Furthermore, if Figure 2 As shown, a water separator 311 is installed at the outlet end of the recovery pipe 31, and a plurality of outlet holes 312 are evenly distributed at the bottom of the water separator 311, and the plurality of outlet holes 312 are distributed above the activated carbon 23. It can be understood that the water separator 311 can evenly divide the water discharged from the recovery pipe 31, and make the water flow from the plurality of outlet holes 312 onto the activated carbon 23 below, so that the activated carbon 23 can be fully cleaned.

[0035] In one embodiment of the present invention, Figure 3 As shown, the drying tube 40 is distributed in an S shape inside the activated carbon 23. It is understandable that such a design can increase the contact area between the drying tube 40 and the activated carbon 23, which is beneficial for the drying tube 40 to fully dry the activated carbon 23, and at the same time, it is beneficial for the drying tube 40 to heat the VOCs gas in the adsorption chamber 20.

[0036] In one embodiment of the present invention, the treatment element may be a catalyst bed. It is understood that after the VOCs are catalytically combusted in the catalyst bed, water, carbon dioxide and heat are generated.

[0037] In summary, the VOCs collection device of the embodiment of the utility model recovers the carbon dioxide, water and heat generated after treatment in the treatment chamber, so that they can flow back to the adsorption chamber and efficiently clean the activated carbon, wherein both water and carbon dioxide have some heat attached to them, water can clean the activated carbon through the recovery pipe, and carbon dioxide can dry the activated carbon through the drying pipe, thereby ensuring the activity of the activated carbon adsorption particles and maintaining the dryness of the activated carbon, thereby achieving energy saving and cost reduction, which is conducive to promotion and application. In addition, the VOCs can be heated before treatment, which is conducive to improving the VOCs treatment efficiency.
