Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically a box-type activated carbon chemical filter for removing VOC gases. Background Technology

[0002] In some applications of detection equipment or components used to detect gases such as CO, H2, and CH4, toxic gases such as SO2, H2S, NO2, and organosilicon are often present, or VOC impurities such as ethanol and formaldehyde may interfere. In such cases, we need to filter and eliminate toxic and impurity gases. There are two main types of filter materials currently used in micro-devices such as gas sensors: one is an adsorbent material based on activated carbon, and the other is an adsorbent material based on porous adsorbents such as activated molecular sieves and alumina. However, existing filter structures usually directly deliver the gas into the filter structure for filtration, which can easily lead to saturation of the activated carbon or adsorbent material, and it is inconvenient to discharge and collect impurities during filtration. Therefore, those skilled in the art have proposed a box-type activated carbon chemical filter for removing VOC gases to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a box-type activated carbon chemical filter for removing VOC gases, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A box-type activated carbon chemical filter for removing VOCs includes a humidification box and an adsorption box. The humidification box is equipped with an air inlet pipe. The top of the humidification box is connected to the top of the adsorption box via a first connecting pipe. A control valve is installed on the first connecting pipe. The bottom of the adsorption box is connected to the top of a filter tube via a second connecting pipe. The filter tube contains a plurality of activated carbon filter sheets. The bottom of the filter tube is connected to a collection box via a plurality of third connecting pipes. The filter tube is arranged horizontally, and the plurality of third connecting pipes are located at the gaps between adjacent activated carbon filter sheets.

[0006] As a further embodiment of this utility model: a liquid exchange pipe is provided at the bottom of the humidification box, and a filter screen is provided at the end of the first connecting pipe near the humidification box.

[0007] As a further embodiment of this utility model: one end of the second connecting pipe extends into the inner cavity of the adsorption box and a filter bucket is connected to that end; a drain pipe is provided on one side of the bottom of the adsorption box.

[0008] As a further embodiment of this utility model: the adsorption box is provided with a first component detector and a second component detector, the second connecting pipe is provided with an air pump, and the outer wall of the adsorption box is provided with a controller and an operation panel. The first component detector, the second component detector and the air pump are all linearly connected to the controller and the control panel.

[0009] As a further improvement of this utility model: the filter tube has openings at both ends, one end of the second connecting tube is connected to the middle of the filter tube, and the thickness of the activated carbon filter sheet gradually decreases along the middle of the filter tube towards both ends.

[0010] As a further improvement of this utility model: the collection box is provided with a storage drawer, the storage drawer can be pulled out from the collection box, a sealing ring is provided at the connection between the storage drawer and the collection box, and one end of the storage drawer extends outside the collection box and is connected to a pull rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This device humidifies and initially adsorbs gases by combining a humidification box and an adsorption box, which can adsorb VOC impurities in the gas. When the gas is subsequently filtered by activated carbon, it will not interfere with the functionality of the activated carbon. Fine impurities will enter the collection box through the third connecting pipe. With the storage drawer set in the collection box, the collection and discharge of impurities is more convenient. The overall device has a simple structure and is easy to operate. It has a good gas purification effect and can effectively protect the activated carbon filter, making it more practical.

The bottom end of the filter tube 16 is connected to the top of a collection box 17 through several third connecting pipes 18. Several activated carbon filter sheets 19 are arranged at equal intervals inside the filter tube 16. Several third connecting pipes 18 are arranged at the gaps between adjacent activated carbon filter sheets 19.

[0022] Please see Figure 2 In this embodiment, a liquid exchange pipe 6 is provided at the bottom of the humidification box 1, a filter screen 7 is provided at one end of the first connecting pipe 4 near the humidification box 1, and further, one end of the second connecting pipe 15 extends into the inner cavity of the adsorption box 3 and is connected to a filter bucket 12.

[0023] Please see Figure 2 In this embodiment, the adsorption box 3 is equipped with a first component detector 8 and a second component detector 9 in its inner cavity, and an air pump 11 is installed in the second connecting pipe 15. A controller 10 and an operation panel 14 are installed on the outer wall of the adsorption box 3.

[0024] Example 2: See Figure 2 , 3 Based on Embodiment 1, the filter tube 16 has openings at both ends, one end of the second connecting tube 15 is connected to the middle of the filter tube 16, and the thickness of the activated carbon filter 19 gradually decreases from the middle of the filter tube 16 to both ends.

[0026] Working principle: When in use, the device delivers gas into the humidification box 1 through the air inlet pipe 2. The humidification box 1 contains a solution that can absorb toxic gases such as SO2, H2S, NO2, and organosilicon. The control valve 5 is opened to discharge the humidified gas into the adsorption box 3. When the water passes through the filter screen 7, excess water is filtered out. The gas enters the adsorption box 3 and is adsorbed and filtered by the adsorption material block 23. After that, the gas enters the filter tube 16, and part of it flows through the activated carbon filter sheet 19 to both ends of the filter tube 16. The impurities accumulated on the activated carbon filter sheet 19 enter the collection box 17 through the third connecting pipe 18. The gas is finally discharged from the port of the filter tube 16 after filtration. Impurities, particles, etc. are precipitated and collected in the storage drawer 20. Then, the storage drawer 20 is taken out by the pull rod 22, and the impurities, particles, etc. can be recycled.
