A deodorization treatment equipment for factory sewage purification

Abstract

The invention discloses a deodorization treatment device for purifying factory sewage, and relates to the technical field of sewage treatment. Before the treatment with adding chemicals, it is necessary to carry out impurity removal treatment on solid impurities in sewage to avoid accidents caused by the reaction between impurities and chemicals. However, when filtering sewage, long-term filtering work leads to clogging of the filter element. Therefore, through the cooperation between the corrugated cylinder and the filter cylinder, after the sewage passes through the filter cylinder, it reaches the gap between the corrugated cylinder and the filter cylinder, and starts to move toward the connecting pipe. At the same time, during the flow of sewage in the gap, the inner diameter of the corrugated cylinder is periodically increased and decreased from one end to the other end, so that when the gap is reduced, the flowing sewage impacts the filter cylinder from the outside to the inside, and washes the impurities of the blocked filter cylinder, so as to avoid flow obstruction due to blockage during the sewage filtration process.

Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to deodorization treatment equipment for purifying factory sewage. Background Art

[0002] At present, factory sewage deodorization equipment is used to remove odorous substances generated in factory sewage. Sewage treatment is an important part of environmental protection. In the process of sewage treatment, some organic waste gas and inorganic waste gas containing sulfur, nitrogen and oxygen will emit odor. In the existing equipment, most of them add neutralizers to the sewage and mix them to complete the deodorization of the sewage.

[0003] In the process of sewage deodorization treatment by adding chemicals, solid impurities in the sewage need to be removed before adding chemicals to avoid unexpected reactions between impurities and chemicals. However, when filtering sewage, long-term filtration work causes clogging of the filter element. Summary of the invention

[0014] 1. The deodorization treatment equipment for sewage purification in this factory cooperates with the bellows and the filter cylinder. After the sewage is filtered by the filter cylinder, it reaches the gap between the bellows and the filter cylinder and begins to move toward the connecting pipe.

[0033] A dosing mechanism 3, which is used to add a deodorizing agent to the sewage, and is fixedly installed inside the reaction tank 1;

[0034] The adsorption mechanism 4 physically adsorbs the suspended matter in the sewage after the sewage reacts with the deodorant by adding an adsorption material, and the adsorption mechanism 4 is installed on a side of the reaction tank 1 close to the outlet pipe 6, and the dosing mechanism 3 is located between the adsorption mechanism 4 and the primary filtration mechanism 2;

[0035] Among them, the primary filter mechanism 2 includes an outer cover tube 21, the inner wall of the outer cover tube 21 is fixedly connected to the outer side of the water inlet pipe 5, and an inner cushion tube 22 is fixedly installed on the inner wall of the outer cover tube 21, and a corrugated tube 24 is fixedly installed on the inner wall of the inner cushion tube 22.

The end of the outer side of the curved column 25 away from the water inlet pipe 5 is an inwardly concave curved surface. During the flow of sewage, the fluctuation of the gap between the corrugated tube 24 and the outer side of the filter tube 26 causes the sewage to be backwashed from the outside of the filter tube 26 to the inside according to the fluctuation of the flow gap during the flow process, and is connected with the dosing mechanism 3 through the connecting pipe 23, so that the sewage from which impurities are removed enters the dosing mechanism 3 for deodorization treatment, and the end of the curved column 25 close to the water inlet pipe 5 is an inwardly concave curved surface at the center position.

[0036] The second embodiment is based on the first embodiment. Figures 5 and 6 and Figures 8 to 9As shown, the dosing mechanism 3 includes a connecting cover 304, one side of the connecting cover 304 is connected to the outer cover tube 21 through the connecting pipe 23, and a hollow cylinder 306 is fixedly installed at the center position of the inner wall of the connecting cover 304, and a conducting pipe 305 is evenly installed on the outer side of the hollow cylinder 306. The end of the conducting pipe 305 away from the hollow cylinder 306 passes through the connecting cover 304 and extends to the outside thereof, and is connected with the drug passing pipe 303 through the drug pipeline. The drug is introduced into the outer ring tube 301 through the drug passing pipe 303 by a pressure pump, and the drug is introduced into the hollow cylinder 306 through the conducting pipe 305. The sewage introduced through the connecting pipe 23 enters the inner side of the connecting cover 304. After the sewage is introduced, as the drug is continuously pressurized and introduced, the pressure inside the hollow cylinder 306 gradually increases, and the hollow cylinder 3 As the internal pressure of 06 gradually increases, the pressure pushes the medicine blocking plate 308 in the direction of the limiting plate 311, causing the slide rod 310 to slide and the compression spring 312 to deform. The end of the guide tube 305 away from the hollow cylinder 306 is fixedly installed with an outer ring tube 301, and a fixed block 302 is fixedly installed on the outside of the outer ring tube 301. The fixed block 302 is evenly installed along the center position of the outer ring tube 301. The outer ring tube 301 is fixedly connected to the inner wall of the reaction tank 1 through the fixed block 302. A medicine passing tube 303 is fixedly installed on the top of the outer ring tube 301. The end of the medicine passing tube 303 away from the outer ring tube 301 penetrates the reaction tank 1 and extends to its outside. A groove tube 307 is fixedly installed on the inner wall of the hollow cylinder 306, and the groove tube 307 is evenly installed along the center position of the hollow cylinder 306.

[0037] The outer side of the groove tube 307 is evenly provided with through grooves, and the inner wall of the groove tube 307 is fixedly installed with a limit plate 311, and the inner wall of the limit plate 311 is slidably installed with a slide rod 310, and the end of the slide rod 310 close to the hollow cylinder 306 is fixedly installed with a medicine stop plate 308, and the outer side of the medicine stop plate 308 is slidably adapted to the inner wall of the groove tube 307, and a spring 312 is fixedly installed between the side of the limit plate 311 away from the medicine stop plate 308 and the inner wall of the groove tube 307. When the pressure reaches a certain level, the medicine stop plate 308 opens the groove The through groove of the tube 307 allows the reagent to be introduced from the through groove into the outside of the hollow tube 306 to react with the filtered sewage so that the odorous substances in the sewage are treated by the reagent and deodorized. During the sliding of the slide bar 310, the connecting block 309 is driven to move together, and during the movement of the connecting block 309, it works together with the adsorption mechanism 4. The connecting block 309 is fixedly installed on one end of the slide bar 310 away from the hollow tube 306, and the slide bar 310 is fixedly connected to the adsorption mechanism 4 through the connecting block 309.

[0038] The third embodiment is based on the first and second embodiments. Figure 7As shown, the adsorption mechanism 4 includes a slot cover 41, the outer side of the slot cover 41 is fixedly connected to the inner wall of the reaction tank 1, and the slot cover 41 is evenly provided with empty slots on one side close to the connecting block 309, and the inner wall of the slot cover 41 is evenly provided with strips 46, and a sliding cover 42 is slidably installed on the inner wall of the slot cover 41, and a groove is provided on the outer side of the sliding cover 42, and the sliding cover 42 is slidably adapted to the strips 46 through the groove, and through the connection between the sliding cover 42 and the connecting block 309, when the sewage is treated with the addition of drugs, the sliding connecting block 309 drives the sliding cover 42 to slide, so that the sliding cover 42 opens the empty slot of the slot cover 41, so that the sewage treated with the addition of drugs is introduced into the slot cover 41 and the water guide cover 45 through the gap between the empty slot of the slot cover 41 and the sliding cover 42, and the side of the sliding cover 42 close to the connecting block 309 is fixedly connected to the end of the connecting block 309 away from the sliding rod 310, and the side of the sliding cover 42 close to the connecting block 309 is tightly fitted with the inner wall of the slot cover 41, and the slot cover 4 A curved block 44 is fixedly installed at the center position of one side away from the connecting block 309, and a water guide cover 45 is fixedly connected to one end of the curved block 44 away from the tank cover 41. A fixed plate 43 is fixedly installed on the inner wall of the water guide cover 45, and grooves are evenly opened on the outer side of the fixed plate 43. Before sewage treatment, an adsorbent material is placed inside the water guide cover 45, and the adsorbent material in the water guide cover 45 is restricted by the fixed plate 43, so that the sewage treated with the dosing continues to react between the tank cover 41 and the water guide cover 45, and gradually enters the water guide cover 45 during the flow of the sewage, and the floccules generated by the deodorization reaction are adsorbed by the adsorbent material filled inside, and the untreated odorous substances in the sewage are adsorbed in cooperation with the dosing mechanism 3 to ensure the deodorization effect, and then the deodorized sewage is discharged through the connection between the water guide cover 45 and the water outlet pipe 6, and the end of the water guide cover 45 away from the curved block 44 is fixedly connected to the water outlet pipe 6.

[0039] When in use, workers connect the undeodorized sewage with the water inlet pipe 5 through a pipe, so that the sewage is introduced into the reaction tank 1 through the water inlet pipe 5. The sewage first flows through the primary filtration mechanism 2, and the solids in the sewage are filtered by the primary filtration mechanism 2. The filtered sewage enters the dosing mechanism 3. Workers connect the reagent with the dosing mechanism 3 through a pipe, and pump it into the dosing mechanism 3 with a pressure pump. The odorous substances in the internal sewage are treated with the reagent. Before the sewage is treated, the adsorption material is filled in the adsorption mechanism 4. During the treatment of the sewage, the adsorption mechanism 4 cooperates with the dosing mechanism 3 to introduce the sewage after the dosing reaction into the adsorption mechanism 4, and the flocculants reacted in the sewage are adsorbed by the adsorption material, and the treated sewage is discharged from the outlet pipe 6 through the adsorption mechanism 4.

[0040] When the solid impurities in the sewage are filtered through the primary filtering mechanism 2, the sewage is introduced into the interior of the reaction tank 1 through the water inlet pipe 5 and directly enters the interior of the filter cartridge 26, so that the sewage directly impacts the arc column 25 inside the filter cartridge 26, and after the impact, the sewage flows to the outside of the filter cartridge 26, and the impurities in the sewage are filtered through the filter holes on the surface of the filter cartridge 26. At the same time, after the sewage reaches the outside of the filter cartridge 26, it begins to move toward the position of the connecting pipe 23. During the flow of the sewage, the gap between the corrugated cylinder 24 and the outside of the filter cartridge 26 fluctuates, so that the sewage is backwashed from the outside of the filter cartridge 26 to the inside according to the fluctuation of the flow gap during the flow process, and is connected with the dosing mechanism 3 through the connecting pipe 23, so that the sewage from which impurities are removed enters the dosing mechanism 3 for deodorization.

[0041] After the sewage enters the dosing mechanism 3, it is connected with the medicine pipe 303 through the medicine pipe, and the medicine is introduced into the outer ring pipe 301 through the medicine pipe 303 by the pressure pump, so that the medicine is introduced into the hollow cylinder 306 through the guide pipe 305, and the sewage introduced through the connecting pipe 23 enters the inner side of the connecting cover 304. After the sewage is introduced, as the medicine is continuously pressurized and introduced, the pressure inside the hollow cylinder 306 gradually increases. In the process of gradually increasing the pressure inside the hollow cylinder 306, the pressure pushes the medicine retaining plate 308 to The limit plate 311 is pushed in the direction to make the slide bar 310 slide and the compression spring 312 deform. When the pressure reaches a certain level, the medicine blocking plate 308 opens the through groove of the groove tube 307, so that the medicine begins to be introduced into the outside of the hollow cylinder 306 through the through groove, and reacts with the filtered sewage, so that the odorous substances in the sewage are treated by the medicine and deodorized. In the process of sliding the slide bar 310, it drives the connecting block 309 to move together, and in the process of moving the connecting block 309, it works together with the adsorption mechanism 4.

[0042] In the adsorption mechanism 4, through the connection between the slide cover 42 and the connection block 309, when the sewage is treated with the drug, the sliding connection block 309 drives the slide cover 42 to slide, so that the slide cover 42 opens the empty slot of the slot cover 41, and the sewage after the drug treatment passes through the gap between the empty slot of the slot cover 41 and the slide cover 42 and is introduced into the space between the slot cover 41 and the water guide cover 45. Before the sewage is treated, the adsorption material is placed inside the water guide cover 45, and the adsorption material in the water guide cover 45 is restricted by the fixed plate 43, so that the sewage after the drug treatment continues to react between the slot cover 41 and the water guide cover 45, and gradually enters the water guide cover 45 during the flow of the sewage, and the flocs produced by the deodorization reaction are adsorbed by the adsorption material filled inside, and the untreated odorous substances in the sewage are adsorbed in cooperation with the drug adding mechanism 3 to ensure the deodorization effect, and then the deodorized sewage is discharged through the connection between the water guide cover 45 and the outlet pipe 6.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
