Description

Technical Field

[0001] The present invention relates to the technical field of waste gas deodorization, and in particular to an industrial waste gas deodorization device and method. Background Art

[0002] Since waste gas is inevitably generated during industrial production, especially in chemical plants, the environmental sanitation department should have a higher level of supervision over factories that generate waste gas. In order to meet the level of waste gas discharge, the factory will be equipped with waste gas treatment equipment. Sewage plants, garbage treatment plants, food plants, pharmaceutical plants, chemical plants, rubber product manufacturers and electroplating plants, etc., because of the different products produced, the waste gas emitted is also different, and there are many types of waste gas. Among them, organic pollutants such as ammonia, hydrogen sulfide, mercaptans, dimethyl sulfide, trimethylamine, formaldehyde, styrene, butyric acid (butyric acid) and phenols can be smelled by human sense and are more harmful to human health.

[0003] Some chemical plants use spraying technology to remove odor from waste gas. However, during the spraying process, some impurities are often mixed into the spray liquid. Although the current water mist spray head is equipped with a mesh structure for filtering impurities, this design has a significant defect: as impurities continue to accumulate, the mesh structure is prone to blockage, which in turn hinders the smooth spraying of the spray liquid. Once blockage occurs, the equipment needs to be repaired immediately, which not only interrupts the continuity of waste gas treatment, but also seriously affects the treatment efficiency.

At the same time, the spray liquid is introduced through the water inlet pipe, and the spray liquid enters the space under the partition in the spray pipe, and is sprayed out in the form of water mist through the water mist nozzle at the lower end, and the exhaust gas is deodorized by the spray liquid;

[0022] S2, filter the impurities in the spray liquid through the filter plate. When a small amount of impurities cause clogging of the filter plate, the spray liquid pushes the filter plate to move to the right. Since there is spray liquid in the spray pipe at this time, the filter plate and the spray liquid are relatively displaced, so that the impurities are separated from the filter plate, and the filter plate is unblocked again and reset under the elastic force of the No. 1 spring. The cycle is repeated many times, so that the filter plate moves back and forth to avoid clogging of the filter plate and keep the water inlet unobstructed;

At the same time, the fixed plate is driven to rotate through the spray pipe and the fixed rod, so that the No. 1 inclined block and the No. 2 inclined block are against each other, and the fixed rod is pushed to move to the right, so that the card block is against the left side of the prismatic block. At this time, the card block cannot limit the prismatic block and the protrusion. Under the elastic force of the No. 1 spring, the rotating gear is driven to reset to the left and re-engage with the ring gear. At this time, the spray pipe rotates 180°, realizing the switching of the upper and lower water mist nozzles;

[0025] S5, when the card block is against the left side of the prismatic block, the convex block is against the alarm trigger to send a reminder to the staff. After the current exhaust gas treatment is completed, the inspection cover is set to facilitate inspection and maintenance.

[0026] Beneficial effects of the present invention:

[0027] 1. Filter the impurities in the spray liquid through the filter plate. When a small amount of impurities block the filter plate, the spray liquid pushes the filter plate to move to the right. Since there is spray liquid in the spray pipe at this time, the filter plate and the spray liquid are relatively displaced, so that the impurities are separated from the filter plate, and the filter plate is unblocked again and reset under the elastic force of the No. 1 spring. The cycle is repeated many times to make the filter plate move back and forth to avoid blockage of the filter plate and keep the water inlet unobstructed;

[0028] 2. When a large amount of impurities cause the filter screen to be completely blocked, the spray liquid pushes the filter screen to move to the right, and the setting of the cross bar, piston plate and push rod pushes the rotating gear to the right, and the rotating gear and the fixed rod drive the protrusion to move to the right, and the clamping block is pressed between the protrusion and the prismatic block, and the protrusion is limited by the clamping block, and at this time the rotating gear is separated from the ring gear;

[0029] 3. When the rotating gear is separated from the ring gear, the exhaust gas pushes the diverter plate to rotate, and the drive gear is driven to rotate by the diverter plate, the vertical rod and the rotating rod. The fixed gear and the spray pipe are driven to rotate by the driving gear, and the fixed plate is driven to rotate by the spray pipe and the fixed rod at the same time, so that the No. 1 bevel block and the No. 2 bevel block are abutted against each other, and the fixed rod is pushed to move to the right, so that the card block abuts against the left side of the prismatic block. At this time, the card block cannot limit the prismatic block and the protrusion. Under the elastic force of the No. 1 spring, the rotating gear is driven to reset to the left and re-engage with the ring gear. At this time, the spray pipe rotates 180°, realizing the switching of the upper and lower water mist nozzles. Therefore, there is no need to perform equipment maintenance immediately, which not only ensures the continuity of exhaust gas treatment, but also improves the treatment efficiency.

[0057] Embodiment 2

[0058] A method for deodorizing industrial waste gas, based on the first embodiment, comprises the following steps:

[0059] S1, the exhaust gas is introduced through the air inlet pipe 102, and is blown to the diverter plate 303 through the fan 104.

[0060] S2, the impurities in the spray liquid are filtered through the filter plate 205. When a small amount of impurities cause blockage to the filter plate 205, the spray liquid pushes the filter plate 205 to move to the right. Since there is spray liquid in the spray pipe 203 at this time, the filter plate 205 and the spray liquid are relatively displaced, so that the impurities are separated from the filter plate 205, and the filter plate 205 is unblocked again and reset under the elastic force of the first spring 210. The cycle is repeated many times, so that the filter plate 205 moves back and forth to avoid blockage of the filter plate 205 and keep the water inlet unobstructed;

[0061] S3, when a large amount of impurities cause the filter screen 205 to be completely blocked, the filter screen 205 is pushed to the right by the spraying liquid, and the rotating gear 209 is pushed to the right by the arrangement of the cross bar 206, the piston plate 207 and the push rod 208, and the protrusion 214 is driven to move to the right by the rotating gear 209 and the fixed rod 213, and the clamping block 218 is pressed between the protrusion 214 and the prismatic block 215, and the protrusion 214 is limited by the clamping block 218, and at this time, the rotating gear 209 is separated from the ring gear 212;

[0062] S4, when the rotating gear 209 is separated from the ring gear 212, the exhaust gas drives the diverter plate 303 to rotate, and the drive gear 305 is driven to rotate through the diverter plate 303, the vertical rod 302 and the rotating rod 304, and the fixed gear 306 and the spray pipe 203 are driven to rotate through the driving gear 305, and the fixed plate 219 is driven to rotate through the spray pipe 203 and the fixed rod 213, so that the first inclined block 220 and the second inclined block 221 are against each other, and the fixed rod 213 is pushed to move to the right, so that the block 218 is against the left side of the prismatic block 215. At this time, the block 218 cannot limit the prismatic block 215 and the protrusion 214. Under the elastic force of the first spring 210, the rotating gear 209 is driven to reset to the left and re-engage with the ring gear 212. At this time, the spray pipe 203 rotates 180°, realizing the switching of the upper and lower water mist nozzles 204;

A method for deodorizing industrial waste gas, using an industrial waste gas deodorizing device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, the waste gas is introduced through the air inlet pipe (102), blown to the diverter plate (303) by the fan (104), and the diverter plate (303) evenly diverts the waste gas. At the same time, the spray liquid is introduced through the water inlet pipe (201), and the spray liquid enters the space below the partition (222) in the spray pipe (203), and is sprayed out in the form of water mist through the water mist nozzle (204) at the lower end, thereby deodorizing the waste gas; S2, filtering impurities in the spray liquid through the filter screen plate (205). When a small amount of impurities causes clogging of the filter screen plate (205), the spray liquid pushes the filter screen plate (205) to move rightward. Since there is spray liquid in the spray pipe (203) at this time, the filter screen plate (205) and the spray liquid are relatively displaced, so that the impurities are separated from the filter screen plate (205), and the filter screen plate (205) is unblocked again and reset under the elastic force of the first spring (210). The cycle is repeated for multiple times, so that the filter screen plate (205) moves back and forth left and right; S3, when a large amount of impurities cause the filter screen plate (205) to be completely blocked, the filter screen plate (205) is pushed to the right by the spraying liquid, and the rotating gear (209) is pushed to the right by the arrangement of the cross bar (206), the piston plate (207) and the push rod (208), and the protrusion (214) is driven to move to the right by the rotating gear (209) and the fixing rod (213), and the clamping block (218) is pressed between the protrusion (214) and the prismatic block (215), and the protrusion (214) is limited by the clamping block (218), and at this time, the rotating gear (209) is separated from the ring gear (212); S4, when the rotating gear (209) is separated from the ring gear (212), the exhaust gas drives the diverter plate (303) to rotate, and the diverter plate (303), the vertical rod (302) and the rotating rod (304) drive the driving gear (305) to rotate, and the driving gear (305) drives the fixed gear (306) and the spray pipe (203) to rotate, and at the same time, the spray pipe (203) and the fixed rod (213) drive the fixed plate (219) to rotate, so that the first inclined block (220) and the second inclined block (220) are rotated. The first bevel block (221) abuts against the second bevel block (221), and pushes the fixing rod (213) to move rightward, so that the clamping block (218) abuts against the left side of the prismatic block (215). At this time, the clamping block (218) cannot limit the prismatic block (215) and the protrusion (214).
