Description

Technical Field

[0001] This utility model belongs to the field of purification device technology, specifically relating to a purification and treatment device for boiling point organic waste gas. Background Technology

[0002] Boiling point organic waste gas usually refers to volatile organic compounds (VOCs) waste gas, which are organic compounds with a boiling point between 50℃ and 260℃ at normal temperature and pressure, which are easily volatilized from solids or liquids and released into the air. They are one of the common air pollutants in industry and daily life.

[0003] The core characteristic of this type of waste gas is "volatility". Its essence is that the intermolecular forces are relatively weak, and it can obtain enough energy at normal ambient temperature to break through the binding of liquid or solid surfaces and diffuse in gaseous form.

[0004] Industrial production is the primary source, including petrochemical processes (such as oil refining and chemical fiber production), coating (spraying paint and printing), pharmaceuticals, plastics processing, rubber manufacturing, and furniture production (adhesive coating and spraying of boards), which release various organic waste gases such as benzene, toluene, xylene, formaldehyde, and ethyl acetate.

[0005] The activated carbon in existing equipment is packed in filter bags and other structures. When replacing it, the entire filter bag needs to be removed manually. This process can easily cause the activated carbon to spill, which not only pollutes the working environment but may also affect the health of the operators. In addition, the replacement efficiency is low. Utility Model Content

[0006] The purpose of this invention is to provide a device for purifying and treating waste gas containing boiling point organic compounds. This device aims to solve the problems in the prior art where the activated carbon inside the existing equipment is filled in the filter bag or other structures. When replacing the activated carbon, the entire device needs to be removed manually, which can easily cause the activated carbon to spill, polluting the working environment and potentially affecting the health of the operators. In addition, the replacement efficiency is low.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a purification treatment device for boiling point organic waste gas, comprising a purification chamber, a cover installed on the surface of the purification chamber, a placement rack welded to the inner wall surface of the purification chamber, a placement groove formed on the front surface of the placement rack, a pull-out mesh frame inserted into the placement groove, a pull-out groove formed on the front surface of the pull-out mesh frame, a guide strip connected to the bottom surface of the pull-out mesh frame, the guide strip slidably connected to the surface of the placement groove, a sealing gasket abutting the front surface of the pull-out mesh frame, a guide groove formed on the surface of the sealing gasket, a guide rod movably inserted into the surface of the guide groove, the guide rod surface connected to the surface of the cover, a spring connected to the surface of the cover, the other side surface of the spring connected to the surface of the sealing gasket, a side sealing strip abutting the surface of the sealing gasket, the side sealing strip being fitted and adhered to the surface of a U-shaped groove, the U-shaped groove being formed on the surface of the cover.

[0008] As a preferred embodiment of the boiling point organic waste gas purification and treatment device of this utility model, the four sets of placement slots are longitudinally and equally spaced on the surface of the placement frame, and the placement slots are an integral structure with a set of trapezoidal grooves symmetrically opened at the bottom of the rectangular grooves.

[0009] As a preferred embodiment of the boiling point organic waste gas purification and treatment device of this utility model, the guide bar is a trapezoidal integrated structure, and the two guide bars are symmetrically distributed at the bottom of the pull-out mesh frame.

[0010] As a preferred embodiment of the boiling point organic waste gas purification and treatment device of this utility model, the pull-out groove is a "U" shaped groove, and its opening end is located at the front end of the pull-out mesh frame.

[0011] As a preferred embodiment of the boiling point organic waste gas purification and treatment device of this utility model, the box cover, sealing gasket, guide groove, guide rod and spring form an elastic connection structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides the following technical solution: a purification treatment device for boiling point organic waste gas, including a purification box body 1, a box cover 2 installed on the surface of the purification box body 1, a placement rack 3 welded to the inner wall surface of the purification box body 1, a placement groove 4 formed on the front surface of the placement rack 3, a pull-out mesh frame 5 inserted into the surface of the placement groove 4, a pull-out groove 6 formed on the front surface of the pull-out mesh frame 5, a guide strip 7 connected to the bottom surface of the pull-out mesh frame 5, the guide strip 7 slidably connected to the surface of the placement groove 4, a sealing gasket 8 abutting the front surface of the pull-out mesh frame 5, a guide groove 9 formed on the surface of the sealing gasket 8, and a guide rod 10 movably inserted into the surface of the guide groove 9. The guide rod 10 is connected to the surface of the box cover 2. The surface of the box cover 2 is connected to the spring 11. The other side of the spring 11 is connected to the surface of the sealing gasket 8. The surface of the sealing gasket 8 abuts against the side sealing strip 12. The side sealing strip 12 is fitted and bonded to the surface of the U-shaped groove 13. The U-shaped groove 13 is opened on the surface of the box cover 2. In this design, the purification box body 1 and the box cover 2 constitute the main body of the activated carbon purification box. A large number of related components are set in the main body of the activated carbon purification box. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.

[0024] The main model of the activated carbon purification box in this solution is: CLW-HT series small activated carbon purification equipment.

[0025] In use: The activated carbon purification box uses a fan to introduce waste gas containing boiling point organic matter into the purification box 1 through the air inlet. The activated carbon placed on the pull-out mesh frame 5 has a strong adsorption force generated by its rich microporous structure. Through intermolecular forces and partial chemical adsorption, it adsorbs organic molecules in the waste gas onto its microporous surface, thus purifying the waste gas. The purified gas is discharged from the air outlet. When the activated carbon is saturated, its activity can be restored through thermal regeneration, chemical regeneration, or by directly replacing it with new activated carbon to continuously ensure the purification effect.

[0026] Preferably, four sets of placement slots 4 are longitudinally and equally spaced on the surface of the placement rack 3, and the placement slots 4 are an integral structure with a set of trapezoidal grooves symmetrically opened at the bottom of a rectangular groove.

[0027] In practical use, place the activated carbon medium in the pull-out mesh frame 5, and then push the pull-out mesh frame 5 towards the end of the placement groove 4 until the pull-out mesh frame 5 abuts against the inner wall surface of the placement rack 3. Then, insert the other three pull-out mesh frames 5 containing activated carbon medium into the placement groove 4 opened on the surface of the placement rack 3 in sequence.

[0028] Preferably, the guide bar 7 is a trapezoidal integrated structure, and the two guide bars 7 are symmetrically distributed at the bottom of the pull-out mesh frame 5.

[0029] In practical use, the guide strip 7 connected to the bottom of the pull-out mesh frame 5 is aligned with the trapezoidal groove on the surface of the placement slot 4, and then the pull-out mesh frame 5 is pushed toward the end of the placement slot 4 until the pull-out mesh frame 5 abuts against the inner wall surface of the placement rack 3.

[0030] Preferably, the pull-out groove 6 is a "U"-shaped groove, with its opening end located at the front end of the pull-out mesh frame 5.

[0031] In practical use, when it is necessary to replace the pull-out mesh frame 5 inserted into the placement slot 4, the open end of the pull-out slot 6 is fastened to facilitate pulling out the pull-out slot 6 inserted into the placement slot 4.

[0032] Preferably, the box cover 2, sealing gasket 8, guide groove 9, guide rod 10 and spring 11 form an elastic connection structure.

[0033] In practical use, the spring 11 that elastically connects the sealing gasket 8 and the box cover 2 elastically abuts against the surface of the pull-out mesh frame 5. At the same time, when the sealing gasket 8 moves under the elastic drive of the spring 11, the guide rod 10 slides and guides in the guide groove 9 to prevent the sealing gasket 8 from shifting on the box cover 2.

[0034] Preferably, the side sealing strip 12 is a U-shaped integrated structure, and its shape and size are adapted to the U-shaped groove 13. The two U-shaped grooves 13 are symmetrically opened on the surface of the box cover 2.

[0035] In practical use, the U-shaped grooves 13 symmetrically opened on the surface of the box cover 2 are used to bond and fix the side sealing strips 12 made of silicone rubber to the box cover 2 with special adhesive.

[0036] Working principle: When purifying waste gas containing boiling point organic compounds using the purification chamber 1, the activated carbon medium is placed in the pull-out mesh frame 5. Then, the guide strip 7 connected to the bottom of the pull-out mesh frame 5 is aligned with the trapezoidal groove on the surface of the placement slot 4. The pull-out mesh frame 5 is then pushed towards the end of the placement slot 4 until it abuts against the inner wall of the placement rack 3. This process is repeated, inserting the other three pull-out mesh frames 5 containing activated carbon medium into the placement slots 4 on the surface of the placement rack 3. Finally, the chamber lid 2 is rotated onto the opening of the purification chamber 1, and the sealing gasket 8 abuts against the pull-out mesh frame 5. On the surface, while the pull-out mesh frame 5 is closed, the side sealing strip 12 bonded to the surface of the lid 2 abuts against the opening end of the purification box body 1. At the same time, the sealing gasket 8 elastically connected to the surface of the lid 2 abuts against the surface of the pull-out mesh frame 5, ensuring that sufficient pressure can be applied to the sealing gasket 8 when the lid 2 is closed, thereby enhancing the sealing effect. When the sealing gasket 8 abuts against the surface of the pull-out mesh frame 5, the spring 11 elastically connected between the sealing gasket 8 and the lid 2 elastically abuts against the surface of the pull-out mesh frame 5. At the same time, when the sealing gasket 8 moves under the elastic drive of the spring 11, the guide rod 10 slides and guides in the guide groove 9, preventing the sealing gasket 8 from shifting its position on the lid 2.

[0037] After long-term use, the above operation can be repeated to remove the pull-out mesh frame 5 inserted into the placement slot 4 and replace the activated carbon medium contained in the pull-out mesh frame 5.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
