Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas filter. Background Technique

[0002] During the production process of a chlor-alkali chemical production workshop, there is a certain amount of waste gas, which contains waste gases such as hydrogen chloride and mercury vapor at a relatively high concentration. If this waste gas is directly discharged into the atmosphere without treatment, it will not only pollute the surrounding environment, but also cause great harm to operators and raw material consumption, and will also have a certain impact on the image of the enterprise. Therefore, it must be treated.

[0003] In the prior art, activated carbon adsorption equipment is generally used to treat waste gas. However, most of the existing activated carbon adsorption equipment is of the type with one inlet and one outlet. The waste gas produces a compression effect on the activated carbon adsorbent. The waste gas flows at a uniform speed and does not form a gradient flow rate according to the different concentrations of the treatment medium. Moreover, after being used for a period of time, the activated carbon will inevitably become inactivated and needs to be regenerated or updated. In particular, the update is very inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waste gas filter to solve the problems proposed in the above background technique, that is, the waste gas produces a compression effect on the activated carbon adsorbent, the waste gas flows at a uniform speed and does not form a gradient flow rate according to the different concentrations of the treatment medium, and after being used for a period of time, the activated carbon will inevitably become inactivated and needs to be regenerated or updated. In particular, the update is very inconvenient.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A waste gas filter includes a housing. An outer sieve plate is arranged inside the housing. A central sieve tube is also connected at the center inside the housing. The top of the central sieve tube penetrates through the top of the housing and is provided with a purified gas outlet. Granular activated carbon is filled between the outer sieve plate and the central sieve tube. A plurality of loading ports and a temperature measuring port are evenly arranged at the top of the housing. Waste gas inlets are symmetrically arranged on both sides of the housing. A plurality of inverted conical discharge ports are evenly arranged at the bottom of the housing. A vibration mechanism is arranged inside each discharge port.

[0007] Further preferably, the vibration mechanism includes a plurality of buffer rods evenly connected to the inner wall of the discharge port. The other end of each buffer rod is evenly connected to the circumferential surface of the mounting rod. One end of the mounting rod is connected with a protective cover, and the other end of the mounting rod is connected with a vibration motor.

[0008] Further preferably, the buffer rod includes a fixed rod and a movable rod. The fixed rod is connected to the inner wall of the discharge port, the movable rod is connected to the circumferential surface of the mounting rod, the fixed rod is sleeved outside the movable rod, and a buffer spring is arranged at the connection between the inner part of the fixed rod and the end face of the movable rod.

[0009] Further preferably, the overall shape of the protective cover is a conical structure, and the diameter of the protective cover is larger than the width of the vibration motor.

[0010] Further preferably, a plurality of through holes are uniformly arranged on the surfaces of the outer sieve plate and the central sieve tube, and a filter net is also sleeved on the surface of the central sieve tube.

[0011] Further preferably, the diameter of the through hole is smaller than the diameter of the granular activated carbon.

[0012] Further preferably, an inspection port is also arranged at the center of the bottom of the housing.

[0013] Further preferably, butterfly valves are also arranged at the loading port and the discharge port.

[0014] Further preferably, a support rod is also arranged inside the housing, and a ladder is arranged on one side of the support rod.

[0015] Further preferably, a manhole is also arranged at the top of the housing.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The waste gas enters the inside of the housing through the waste gas inlet, and after throttling by the outer sieve plate, the waste gas gradually increases in speed and drifts upward from slow speed to the center of the housing, extending the adsorption time of the granular activated carbon filled between the outer sieve plate and the central sieve tube, and having an upward thrust on the granular activated carbon filled between the outer sieve plate and the central sieve tube, enabling the waste gas to better contact the granular activated carbon.

[0018] A vibration mechanism is also arranged at the discharge port, which can prevent blockage of the discharge port when regenerating or updating the granular activated carbon. The manhole at the top of the housing cooperates with the internal ladder to facilitate the maintenance of the inside of the housing, and the inspection port at the bottom of the housing facilitates the inspection of the connection between each discharge port and the housing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 - Figure 2 , the present invention provides a technical solution:

[0024] An exhaust gas filter includes a housing 1, an outer sieve plate 2 is arranged inside the housing 1, a central sieve tube 10 is also connected at the center inside the housing 1, a purified gas outlet 5 is arranged at the top of the central sieve tube 10 through the top of the housing 1, granular activated carbon is filled between the outer sieve plate 2 and the central sieve tube 10, a plurality of loading ports 3 and a temperature measurement port 6 are evenly arranged at the top of the housing 1, exhaust gas inlets 11 are symmetrically arranged on both sides of the housing 1, and a plurality of inverted conical discharge ports 13 are evenly arranged at the bottom of the housing 1. A vibration mechanism 12 is also arranged inside each discharge port 13.

[0025] In the present invention, the vibration mechanism 12 includes a plurality of buffer rods 17 evenly connected to the inner wall of the discharge port 13. The other end of each buffer rod 17 is evenly connected to the circumferential surface of the mounting rod. One end of the mounting rod is connected with a protective cover 16, and the other end of the mounting rod is connected with a vibration motor 18. The buffer rod 17 includes a fixed rod and a movable rod. The fixed rod is connected to the inner wall of the discharge port 13, and the movable rod is connected to the circumferential surface of the mounting rod. The fixed rod is sleeved outside the movable rod, and a buffer spring is arranged at the connection between the inner part of the fixed rod and the end face of the movable rod. The protective cover 16 is integrally in a conical structure, and the diameter of the protective cover 16 is larger than the width of the vibration motor 18.

[0026] In the present invention, a plurality of through holes are evenly arranged on the surfaces of the outer sieve plate 2 and the central sieve tube 10, and a filter screen is also sleeved on the surface of the central sieve tube 10. The diameter of the through hole is smaller than the diameter of the granular activated carbon.

[0027] In the present invention, an inspection port 14 is also arranged at the center of the bottom of the housing 1.

[0028] In the present invention, butterfly valves 15 are also arranged at the loading ports 3 and the discharge ports 13.

[0029] In the present utility model, a support rod 8 is further arranged inside the housing 1, and a ladder 9 is arranged on one side of the support rod 8. A manhole 7 is further arranged at the top of the housing 1. The ladder 9 and the manhole 7 cooperate to facilitate the maintenance of the inside of the housing 1.

[0030] Embodiment: When in use, first open the butterfly valves 15 at the plurality of charging ports 3, and fill granular activated carbon between the outer sieve plate 2 and the central sieve tube 10 inside the housing 1. After filling, close the butterfly valves 15 at the charging ports 3. Then connect the waste gas generated in the chlor-alkali chemical production workshop to the waste gas inlet 11. The waste gas enters the inside of the housing 1 through the waste gas inlet 11 and is throttled by the outer sieve plate 2. The waste gas gradually increases in speed from slow to above the center of the housing 1 and drifts, prolonging the adsorption time of the granular activated carbon filled between the outer sieve plate 2 and the central sieve tube 10, and having an upward thrust on the granular activated carbon filled between the outer sieve plate 2 and the central sieve tube 10, enabling the waste gas to better contact the granular activated carbon, thereby enhancing the adsorption efficiency. Finally, the purified waste gas is discharged through the purified gas outlet 5. A plurality of through holes are uniformly arranged on the surfaces of the outer sieve plate 2 and the central sieve tube 10, and a filter screen is further sleeved on the surface of the central sieve tube 10. The diameter of the through holes is smaller than the diameter of the granular activated carbon, facilitating the flow of the waste gas.

[0031] When it is necessary to update or regenerate the granular activated carbon filled between the outer sieve plate 2 and the central sieve tube 10, open the butterfly valve 15 at the discharge port 13, and drive the protective cover 16 with a conical structure at the top of the mounting rod to vibrate through the vibration motor 18. During the vibration process, the buffer rod 17 can reduce the vibration of the vibration motor 18 on the discharge port 13 under the action of the movable rod, the fixed rod and the buffer spring, thereby reducing the vibration of the housing 1. Only the granular activated carbon at the discharge port 13 needs to be vibrated, thereby preventing the granular activated carbon from blocking the discharge port 13.
