Description

Technical Field

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

[0002] An exhaust gas processor is a device used to treat and purify exhaust gas. Its main function is to remove harmful substances in the generated exhaust gas or convert them into harmless substances to reduce pollution to the environment and protect human health.

[0003] At present, the exhaust gas treatment system is usually composed of a variety of different exhaust gas processors. Different exhaust gas processors have different functions. However, the exhaust gas treated by multiple exhaust gas processors can meet environmental protection standards and be discharged. In the exhaust gas treatment system, the exhaust gas processor located at the front end is usually a dust particle processor, which can remove dust particles in the waste, such as a convenient and clean dust exhaust gas treatment device disclosed in patent publication number CN209549045U.

[0004] At present, when removing dust particles in the exhaust gas at the front end, the exhaust gas treatment device usually uses dust filters to intercept the dust particles. However, during use, the mesh of the dust filter is most likely to be clogged. There are many ways to deal with the clogged mesh, such as using striking vibration or scraping to make the clogged dust fall out of the mesh. However, in actual applications, the dust filters are usually regularly inspected and maintained by relevant personnel. If the dust filter is clogged during the window period of regular inspection and maintenance, the personnel cannot clean the blockage in time. At this time, the ventilation efficiency of the dust filter is prone to gradually decrease due to blockage, affecting the stability of the exhaust gas passage. At the same time, if the blockage is not dealt with in time, it is also easy to increase the dust content in the exhaust gas after filtration, thereby affecting the stability of the exhaust gas treatment effect.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a stable exhaust gas processor.

[0026] The utility model provides Figure 1-4 A stable exhaust gas processor shown includes a chassis 1, wherein two processing chambers 2 are arranged inside the chassis 1, and a three-way pipe 3 is commonly plugged into the two processing chambers 2, and two first control valves 4 are arranged inside the three-way pipe 3, and movable frames 5 are arranged inside the two processing chambers 2, and stainless steel filter screens 6 are fixedly installed inside the two movable frames 5, and the two stainless steel filter screens 6 and the same-side processing chamber 2 are commonly installed with a trigger prompt mechanism, and a group of air outlet pipes 7 are fixedly plugged into the cavity walls of the two processing chambers 2, and a second control valve 8 is installed inside each air outlet pipe 7, and a T-shaped exhaust pipe 9 is commonly fixedly plugged into the pipe ends of the two groups of air outlet pipes 7;

[0027] The trigger prompt mechanism includes a cylinder 10 fixedly installed on the side wall of the stainless steel filter 6, and a support column 11 is slidably connected inside the cylinder 10. The support column 11 is fixedly installed on the side wall of the processing chamber 2 on the same side, and a pressure switch 12 is fixedly installed on the end of the support column 11. Sound and light alarms 13 are fixedly installed on the two outer walls of the chassis 1. The two sound and light alarms 13 are electrically connected to the pressure switch 12 on the same side. The two movable frames 5 and the processing chamber 2 on the same side are jointly installed with an elastic reset component.

[0028] A third control valve 14 is installed inside the T-shaped exhaust pipe 9, and an exhaust hole 15 is provided on the side wall of the two processing chambers 2 located on the opposite side of the outlet pipe 7 on the same side, and a dust filter cloth 16 is installed inside the exhaust hole 15. A removable sealing cover plate 17 is installed on the side wall of the chassis 1. Through this arrangement, the airflow after dust filtration on one side can be used to back-blow and clean the stainless steel filter 6 on the other side.

[0029] The two elastic reset components include a plurality of slide bars 18 fixedly arranged on the side wall of the movable frame 5, a plurality of fixed blocks 19 are fixedly installed on the cavity wall of the processing chamber 2, and each slide bar 18 is slidably connected to the corresponding side wall of the fixed block 19, and a spring 20 is fixedly arranged between each fixed block 19 and the movable frame 5 on the same side. Through this arrangement, the movable frame 5 can be easily moved back and reset.

[0030] The pipe wall of the T-shaped exhaust pipe 9 is fixedly connected with two symmetrically arranged insulating slot boxes 21, a spotlight 22 is fixedly installed at the bottom of one insulating slot box 21, and a photoresistor 23 is fixedly installed at the bottom of the other insulating slot box 21, and the slots of the two insulating slot boxes 21 are fixedly encapsulated with transparent plates 24, the outer wall of the chassis 1 is fixedly installed with a machine box 25, and the inside of the machine box 25 is fixedly installed with a power-off delay relay 26 and an electromagnetic switch 27, the electromagnetic switch 27 is electrically connected to the photoresistor 23, the outer wall of the insulating slot box 21 is fixedly installed with a buzzer 28, and the electromagnetic switch 27 communicates with the buzzer through the power-off delay relay 26. The buzzer 28 is electrically connected. If there is a large amount of dust in the exhausted exhaust gas, the dust will block the light to a certain extent. At this time, the light intensity projected by the spotlight 22 to the photoresistor 23 is reduced, and the resistance of the photoresistor 23 itself is also reduced, so that the current passing into the electromagnetic switch 27 can be increased. At this time, the electromagnetic switch 27 is magnetically closed, so that the buzzer 28 can alarm, and the electromagnetic switch 27 is disconnected again in time. Under the action of the power-off delay relay 26, the buzzer 28 can still maintain the alarm work for 10 minutes, ensuring that when there is a large amount of dust in the exhausted exhaust gas, it can remind personnel to inspect and maintain the device.

[0031] A discharge hopper 29 is fixedly inserted into the lower chamber wall of the two processing chambers 2, and a detachable bottom cover 30 is installed at the bottom of the discharge hopper 29. Through this arrangement, dust trapped inside the processing chamber 2 can be easily discharged.

[0032] When the stable exhaust gas processor is in use, the first control valve 4 on one side and the second control valve 8 inside the corresponding set of exhaust pipes 7 are opened. At this time, the exhaust gas will enter the processing chamber 2 on this side through the three-way pipe 3. The stainless steel filter 6 can filter and retain the dust in the exhaust gas. If the dust blocks the stainless steel filter 6, the ventilation efficiency of the stainless steel filter 6 becomes low. At this time, the air pressure on the air inlet side of the stainless steel filter 6 increases, so that the stainless steel filter 6 can be pushed to drive the movable frame 5 to move, and then the cylinder 10 can be driven to squeeze the pressure switch 12 on the same side. At this time, the corresponding sound and light alarm 13 will give an alarm prompt. At this time, the personnel should open the first control valve 4 and the second control valve 8 on the other side, and close the first control valve 4 and the second control valve 8 on this side. At this time, the exhaust gas will pass through the processing chamber 2 on the other side. Then, the personnel can clean the dust blocked on the stainless steel filter 6 on this side.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
