Description

Technical Field

[0001] The utility model relates to the technical field of adsorption devices, in particular to a VOCs adsorption device. Background Art

[0002] Volatile organic compounds, commonly referred to as VOCs, refer to organic compounds with a saturated vapor pressure greater than 70Pa at room temperature and a boiling point below 260°C at normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10Pa at 20°C and are volatile. They are usually divided into several categories: non-methane hydrocarbons (NMHCs for short), oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organic compounds. VOCs participate in the formation of ozone and secondary aerosols in the atmospheric environment, and have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic.

[0003] At present, VOCs are usually treated by activated carbon adsorption. Although the activated carbon filter can play a good adsorption role, the solid particles of VOCs can easily clog the activated carbon layer, which requires relevant personnel to always pay attention to the clogging of the filter and remove the clogged filter for cleaning, which is not only labor-intensive but also inconvenient. Based on this, we propose a VOCs adsorption device for improvement. Utility Model Content

[0004] The main purpose of the utility model is to provide a VOCs adsorption device, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A VOCs adsorption device comprises an adsorption box, wherein the upper end of the adsorption box is rotatably connected to a box cover, mounting columns and four filter frames are respectively arranged inside the adsorption box, activated carbon filters are fixedly arranged on the four filter frames, and the front and rear ends of the adsorption box are respectively fixedly connected to an input pipe and an output pipe.

[0007] As a further solution of the utility model, a water inlet pipe is fixedly sleeved on the box cover, a five-way pipe is fixedly connected to the lower end of the water inlet pipe, four spray plates are fixedly connected to the five-way pipe, and multiple spray heads are fixedly connected to the outer walls of the four spray plates.

[0008] As a further solution of the utility model, the four spray plates are fixedly connected to the lower end surface of the box cover, and the multiple spray heads are evenly distributed on the upper end of the activated carbon filter.

[0009] As a further solution of the utility model, four water guide ports are fixedly opened on the bottom plate of the adsorption box, a connecting groove is opened in the bottom plate of the adsorption box, and the four water guide ports are interconnected through the four connecting grooves.

[0010] As a further solution of the utility model, a sewage pipe is fixedly sleeved on the bottom plate of the adsorption box, a valve is rotatably connected to the sewage pipe, and the sewage pipe is connected to one of the water guide ports.

[0011] As a further solution of the utility model, the four filter frames are all slidably sleeved on mounting posts, and the mounting posts are fixedly connected to the bottom plate of the adsorption box.

[0012] As a further solution of the utility model, support legs are fixedly connected to the lower end surface of the adsorption box near the four corners, and anti-slip pads are fixedly connected to the lower ends of the four support legs.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting a mounting column in the middle of the filter box, and then installing four filter frames on the four directions of the mounting column, VOCs enter the adsorption box through the input pipe and are filtered through the activated carbon filters on both sides. When the activated carbon filter on one side is blocked, the air pressure on that side increases, and the gas will be filtered through the activated carbon filter on the front side and then enter the other side for circulation, avoiding the situation of gas blockage and circulation, so that relevant personnel do not need to pay attention to the filter blockage at all times, and avoid wasting a lot of energy on observing the gas circulation.

[0015] By connecting the water inlet pipe through the five-way pipe, the clean water source connected to the water inlet pipe can be introduced into the spray plate, and then sprayed out through the nozzle, automatically cleaning the filter, thereby increasing the service life of the filter. At the same time, the waste liquid generated by cleaning can enter the connecting groove through the water guide port, and finally be discharged and treated through the sewage pipe, which is practical.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a VOCs adsorption device includes an adsorption box 1, the upper end of the adsorption box 1 is rotatably connected to a box cover 3, the adsorption box 1 is respectively provided with a mounting column 8 and four filter frames 9, the four filter frames 9 are all fixedly provided with an activated carbon filter 10, and the front and rear ends of the adsorption box 1 are respectively fixedly connected to an input pipe 15 and an output pipe 16.

[0023] In this embodiment, a water inlet pipe 4 is fixedly sleeved on the box cover 3, a five-way pipe 5 is fixedly connected to the lower end of the water inlet pipe 4, four spray plates 6 are fixedly connected to the five-way pipe 5, and multiple nozzles 7 are fixedly connected to the outer walls of the four spray plates 6. The water inlet pipe 4 is connected to an external clean water source, which is introduced into the four spray plates 6 through the five-way pipe 5 and finally sprayed out from the nozzles 7.

[0024] In this embodiment, the four spray plates 6 are fixedly connected to the lower end surface of the box cover 3, and the multiple spray heads 7 are evenly distributed on the upper end of the activated carbon filter 10, so as to facilitate comprehensive cleaning of the activated carbon filter 10 through the spray heads 7.

[0025] In this embodiment, four water guide ports 11 are fixedly provided on the bottom plate of the adsorption box 1, a connecting groove 12 is provided in the bottom plate of the adsorption box 1, and the four water guide ports 11 are interconnected through the four connecting grooves 12 to facilitate the diversion of wastewater.

[0026] In this embodiment, a sewage pipe 13 is fixedly sleeved on the bottom plate of the adsorption box 1, and a valve 14 is rotatably connected to the sewage pipe 13. The sewage pipe 13 is connected to one of the water guide ports 11. The valve 14 can be opened to discharge waste water through the sewage pipe 13.

[0027] In this embodiment, the four filter frames 9 are all slidably connected to the mounting posts 8 , and the mounting posts 8 are fixedly connected to the bottom plate of the adsorption box 1 , so as to facilitate the quick disassembly and assembly of the filter frames 9 .

[0028] In this embodiment, support legs 2 are fixedly connected to the lower end surface of the adsorption box 1 near the four corners, and anti-slip pads are fixedly connected to the lower ends of the four support legs 2 for stably supporting the adsorption box 1 .

[0029] It should be noted that the utility model is a VOCs adsorption device. When in use, VOCs are introduced into the adsorption box 1 through the input pipe 15, and then filtered and adsorbed by the activated carbon filter screens 10 located on both sides, and then discharged from the output pipe 16. When the activated carbon filter screen 10 on one side is blocked, the air pressure will increase, and the VOCs will enter the other side through the activated carbon filter screen 10 located on the front side. At this time, the activated carbon filter screen 10 located on the front side plays a filtering role instead of the activated carbon filter screen 10 that has lost its adsorption effect, extending the adsorption and filtration time of the device and avoiding frequent replacement of the filter screen.

[0030] In the above process, when the machine is shut down regularly to clean and replace the filter, the water inlet pipe 4 can be connected to a clean water source, and then the liquid can be introduced into the spray plate 6 through the five-way pipe 5, and then sprayed out through multiple nozzles 7 to automatically clean the surface of the activated carbon filter 10. The sewage generated by cleaning is guided through the water guide port 11 and the connecting groove 12, and finally enters the sewage pipe 13, which is convenient for centralized discharge treatment.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
