Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a device for treating and purifying industrial waste gas. Background Technology

[0002] Industrial waste gas adsorption treatment is a widely used and highly efficient purification technology. Its core principle is to selectively capture gaseous pollutants in waste gas by utilizing the large specific surface area and surface chemical properties of porous solid adsorbents. Industrial waste gas has a complex composition and often contains harmful components such as volatile organic compounds, malodorous substances, and sulfides. Direct emission would seriously pollute the environment and endanger health. When waste gas passes through the adsorbent bed, pollutant molecules are firmly bound within the pores of the adsorbent under the action of van der Waals forces and chemical bonds, thereby achieving separation from the gas flow and releasing clean gas. After the adsorbent is saturated, it can be regenerated through thermal desorption, steam purging, etc., achieving recycling and reducing operating costs.

[0003] A search revealed Chinese patent publication number CN216171199U, which discloses a resin adsorption-desorption-condensation and recovery device for industrial waste gas purification. The device includes a purification chamber, a spring-loaded component, and a mixing component. An inlet pipe and an outlet pipe are installed on the two end side walls of the purification chamber, respectively. A door is also installed on the front side wall of the purification chamber. The spring-loaded component, used to agitate resin particles, is installed inside the purification chamber. The mixing component, used to accelerate the contact reaction and purification of waste gas and resin particles, is also installed inside the purification chamber.

[0004] To address the problem that the above-mentioned technologies cannot perform online desorption of the adsorption resin and require shutdown to remove the resin before desorption can be performed, which is cumbersome, a new device for industrial waste gas treatment and purification is proposed.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the adsorption diagrams and descriptions are considered to be exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5As shown, an equipment for treating and purifying industrial waste gas includes an adsorption box 1 installed on one side of a secondary treatment zone 2. A rotary motor 4 is fixedly connected to the top of the adsorption box 1, and an outlet pipe 5 is fixedly connected to the top of the secondary treatment zone 2. The secondary treatment zone 2 is preferably a photo-oxidation treatment component, which can perform photo-oxidation secondary treatment on the gas after adsorption before discharging it from the outlet pipe 5. A filter box 8 is fixedly connected to the bottom of the adsorption box 1. An adsorption bracket 17 is rotatably connected inside the adsorption box 1, and a filter bracket 20 is rotatably connected inside the filter box 8. A rotating shaft 28 is fixedly connected to the power output end of the rotary motor 4. The rotating shaft 28 is fixedly connected to the inner side of the adsorption bracket 17 and the filter bracket 20. Multiple adsorption resins 18 are fixedly connected to the side wall of the 17th filter bracket 20, and multiple filter media 21 are fixedly connected to the side wall of the filter bracket 20. There are four slots on the inside and outside of the adsorption box 1. There are four slots on the top and bottom sides of the filter box 8. A high-pressure hot air blower 3 is fixedly connected to one side of the adsorption box 1. The air outlet of the high-pressure hot air blower 3 is attached to the external slot on one side of the adsorption box 1. The air inlet of the secondary treatment zone 2 is attached to the external slot on the other side of the adsorption box 1. An adsorption air supply pipe 6 and a backflushing air supply pipe 7 are fixedly connected to the bottom of the adsorption box 1. The upper interfaces of the adsorption air supply pipe 6 and the backflushing air supply pipe 7 are attached to the slots on both sides inside the adsorption box 1. The lower parts of the adsorption air supply pipe 6 and the backflushing air supply pipe 7 are respectively attached to the two slots on the top of the filter box 8.

[0031] The filter housing 8 has a slotted area at the bottom fitted with a backwash exhaust pipe 9 and an air inlet pipe 10. One end of the backwash exhaust pipe 9 is fixedly connected to an external air bag via a pipe, and one end of the air inlet pipe 10 is fixedly connected to the air supply assembly via a pipe.

[0032] When in use, the gas supply component sprays out gas through the air inlet pipe 10. After the large dust particles are filtered by the filter material 21, the gas is adsorbed by the adsorption resin 18 through the adsorption supply pipe 6. After the adsorption is completed, the gas enters the secondary treatment zone 2 for secondary treatment and then is discharged.

[0033] On the other side, the high-pressure hot air blower 3 can spray out high-pressure and high-temperature airflow to backwash and desorb the adsorption resin 18. Then the desorbed gas will pass through the backwash air supply pipe 7 and let the gas rush into the filter material 21 below to backwash the filter material 21.

[0034] Because the adsorption resin 18 and filter media 21 are separated by the adsorption bracket 17 and the filter bracket 20 during installation, only one piece of adsorption resin 18 and filter media 21 can be used at a time. After a period of use, the adsorption resin 18 and filter media 21 become saturated. At this time, the rotary motor 4 drives the rotary shaft 28 to rotate, and a new adsorption resin 18 and filter media 21 are replaced and aligned with the adsorption air supply pipe 6 and the air inlet pipe 10. The saturated adsorption resin 18 and filter media 21 are rotated and aligned with the high-pressure hot air blower 3 and the backflushing air supply pipe 7 for backflushing cleaning. This allows for the cyclic cleaning of the adsorption resin 18 and filter media 21 without stopping the machine, thus improving the gas treatment efficiency.

[0035] In this embodiment, the adsorption support 17 has an adsorption sealing groove 19 at the connection with the adsorption resin 18, and the filter support 20 has a filter sealing groove 22 at the contact with the filter material 21. The outer edge of the adsorption sealing groove 19 is the same as the groove size of the adsorption box 1, and the filter sealing groove 22 is the same as the groove size of the filter box 8.

[0036] An upper clamping bracket 15 is fixedly connected to the outside of the adsorption box 1. A synchronous screw assembly 25 is rotatably connected inside the upper clamping bracket 15. A clamping motor 16 is fixedly connected to one side of the upper clamping bracket 15. One end of the synchronous screw assembly 25 is fixedly connected to the power output end of the clamping motor 16. The two ends of the synchronous screw assembly 25 are threadedly connected to an outer sealing plate 23 and an inner sealing plate 24. The synchronous screw assembly 25 consists of two double-headed screws. The other ends of the outer sealing plate 23 and the inner sealing plate 24 are slidably connected to one end of the adsorption box 1. The other ends of the outer sealing plate 23 and the inner sealing plate 24 are slidably connected to the slot in the adsorption box 1. The outer sealing plate 23 and the inner sealing plate 24 can be inserted into the adsorption sealing groove 19.

[0037] The outer sealing plate 23 and the inner sealing plate 24 are slidably connected to the slot of the adsorption box 1 on the outside, and are slidably connected to the outside of the corresponding high-pressure hot air blower 3, adsorption air supply pipe 6, backflushing air supply pipe 7 and secondary treatment zone 2 air inlet respectively. Preferably, the outer sealing plate 23 and the inner sealing plate 24 are made of rubber, which can fill the gaps and achieve a better sealing effect. When the synchronous screw assembly 25 rotates, it can drive the two sets of outer sealing plates 23 and inner sealing plates 24 on both sides to move simultaneously and insert into the corresponding adsorption sealing groove 19 to seal the contact between the high-pressure hot air blower 3, adsorption air supply pipe 6, backflushing air supply pipe 7 and secondary treatment zone 2 and adsorption resin 18 to prevent gas leakage.

[0038] In this embodiment, a lower clamping bracket 14 is fixedly connected to the outside of the filter box 8, and an electric screw 26 is fixedly connected to one end of the lower clamping bracket 14. Filter sealing plates 27 are slidably connected in the slots on both sides of the filter box 8. One end of the filter sealing plate 27 is threaded to the electric screw 26 through a screw nut, and one end of the filter sealing plate 27 can be inserted into the filter sealing groove 22.

[0039] Preferably, the material of the filter sealing insert 27 is the same as that of the outer sealing insert 23 and the inner sealing insert 24. The two filter sealing inserts 27 at the same height are connected to a screw nut at one end of the bracket.

[0040] The outer side is slidably connected to the inner side of the slot in the filter box 8. The inner sides of the two upper filter sealing plates 27 are slidably connected to the adsorption air supply pipe 6 and the backflushing air supply pipe 7, respectively. The inner sides of the two lower filter sealing plates 27 are slidably connected to the backflushing exhaust pipe 9 and the air inlet pipe 10, respectively. The electric screw 26 has a double-headed screw end. When started, it can drive the four filter sealing plates 27 on the upper and lower sides to be inserted into the filter sealing groove 22 to seal and prevent gas leakage.

[0041] In this embodiment: When in use, the gas supply component sprays out gas through the air inlet pipe 10, filters large dust particles through the filter material 21, and then passes through the adsorption supply pipe 6 and adsorption resin 18 for adsorption. After adsorption, the gas enters the secondary treatment zone 2 for secondary treatment and is then discharged.

[0042] On the other side, the high-pressure hot air blower 3 can spray out high-pressure and high-temperature airflow to backwash and desorb the adsorption resin 18. Then the desorbed gas will pass through the backwash air supply pipe 7 and let the gas rush into the filter material 21 below to backwash the filter material 21.

[0043] Because the adsorption resin 18 and filter media 21 are separated by the adsorption bracket 17 and the filter bracket 20 during installation, only one piece of adsorption resin 18 and filter media 21 can be used at a time. After a period of use, the adsorption resin 18 and filter media 21 become saturated. At this time, the rotary motor 4 drives the rotary shaft 28 to rotate, and a new adsorption resin 18 and filter media 21 are replaced and aligned with the adsorption air supply pipe 6 and the air inlet pipe 10. The saturated adsorption resin 18 and filter media 21 are rotated and aligned with the high-pressure hot air blower 3 and the backflushing air supply pipe 7 for backflushing cleaning. This allows for the cyclic cleaning of the adsorption resin 18 and filter media 21 without stopping the machine, thus improving the gas treatment efficiency.

[0044] The outer sealing plate 23 and the inner sealing plate 24 are made of rubber, which can fill gaps and achieve a better sealing effect. When the synchronous screw assembly 25 rotates, it can drive the two sets of outer sealing plates 23 and inner sealing plates 24 on both sides to move simultaneously and insert into the corresponding adsorption sealing groove 19 to seal the high-pressure hot air blower 3, adsorption air supply pipe 6, backflushing air supply pipe 7 and the secondary treatment area 2 at the joint with the adsorption resin 18 to prevent gas leakage.

[0045] The filter sealing plate 27 is made of the same material as the outer sealing plate 23 and the inner sealing plate 24. The two filter sealing plates 27 at the same height are connected by a screw and nut at one end of the bracket.

[0046] The outer side is slidably connected to the inner side of the slot in the filter box 8. The inner sides of the two upper filter sealing plates 27 are slidably connected to the adsorption air supply pipe 6 and the backflushing air supply pipe 7, respectively. The inner sides of the two lower filter sealing plates 27 are slidably connected to the backflushing exhaust pipe 9 and the air inlet pipe 10, respectively. The electric screw 26 has a double-headed screw end. When started, it can drive the four filter sealing plates 27 on the upper and lower sides to be inserted into the filter sealing groove 22 to seal and prevent gas leakage.

[0047] Example 2:

[0048] An industrial waste gas treatment and purification device is described in this embodiment, which is based on Embodiment 1 with the following improvements: Figure 1-5 As shown,

[0049] In this embodiment, an air storage tank 11 is installed in the middle of the backflow air supply pipe 7. A one-way valve 12 is fixedly connected above the air storage tank 11, and a solenoid valve 13 is fixedly connected below the air storage tank 11. The other ends of the one-way valve 12 and the solenoid valve 13 are respectively fixedly connected to the backflow air supply pipe 7.

[0050] A pressure valve is located on one side of the gas storage tank 11 to monitor the pressure inside the gas storage tank 11. The solenoid valve 13 is normally closed, so the gas entering from the backflushing gas supply pipe 7 will be stored in the gas storage tank 11. When the pressure inside the gas storage tank 11 reaches a certain value, the solenoid valve 13 is opened to allow high-pressure gas to backflush the filter material 21 below, thereby improving the cleaning effect. The one-way valve 12 above is a gas one-way valve, which can prevent the pressure inside the gas storage tank 11 from causing liquid backflushing.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
