A petrochemical waste gas filtration and diversion device

Abstract

This utility model discloses a petrochemical waste gas filtration and diversion device, specifically relating to the field of waste gas filtration technology. It includes a waste gas filtration mechanism, a dust removal mechanism installed on the rear side of the inner surface of the waste gas filtration mechanism, a wastewater filtration mechanism installed on the rear side of the bottom of the waste gas filtration mechanism, and adsorption mechanisms symmetrically installed on the front side of the inner surface of the waste gas filtration mechanism. In use, the waste gas first passes through the dust removal mechanism for water spraying and dust suppression, which can quickly reduce the dust content in the waste gas and prevent large dust particles from clogging or causing wear to subsequent filtration stages. Furthermore, the wastewater after dust suppression at the dust removal mechanism can be filtered and settled through the wastewater filtration mechanism, thus saving water resources. The initially filtered waste gas then passes through the adsorption mechanism for secondary adsorption of impurities. The combination of the adsorption mechanism and the dust removal mechanism improves the filtration effect of the waste gas.

Description

Technical Field

[0001] This utility model relates to the field of waste gas filtration technology, and in particular to a petrochemical waste gas filtration and diversion device. Background Technology

[0002] During the production process in the petrochemical industry, a large amount of waste gas containing various harmful substances is generated. If this waste gas is discharged directly without effective treatment, it will not only cause serious pollution to the atmospheric environment and damage the ecological balance, but may also threaten the health of surrounding residents.

[0003] Currently, most existing petrochemical waste gas filtration devices only have a single filtration method, such as relying solely on adsorption or simple filter screen filtration. For complex petrochemical waste gases, this single method is difficult to comprehensively and efficiently remove various pollutants, resulting in poor filtration effect and the exhaust gas emissions failing to meet increasingly stringent environmental standards.

[0004] In most existing technologies, the filtration and diversion devices for petrochemical waste gas use a relatively simple filtration method, which may result in poor filtration effect. Furthermore, they lack a structure for easy cleaning or replacement of the filtration device, which makes cleaning and maintenance of the device in actual use inconvenient. Utility Model Content

[0005] The main purpose of this utility model is to provide a petrochemical waste gas filtration and diversion device, which can effectively solve the problems mentioned above. In most existing technologies, the filtration method of most petrochemical waste gas filtration and diversion devices is relatively simple, which may lead to poor filtration effect. In addition, there is a lack of a structure for easy cleaning or replacement of the filter device, which makes it inconvenient to clean and maintain the device in actual use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A petrochemical waste gas filtration and diversion device includes a waste gas filtration mechanism, a dust removal mechanism installed on the rear side of the inner surface of the waste gas filtration mechanism, a wastewater filtration mechanism provided on the rear side of the bottom of the waste gas filtration mechanism, and adsorption mechanisms symmetrically installed on the front side of the inner surface of the waste gas filtration mechanism.

[0009] Preferably, the exhaust gas filtration mechanism includes a filter box, and ventilation baffles are symmetrically fixedly connected to the inner surface of the filter box.

[0010] Preferably, the dust removal mechanism includes a nozzle, which is fixedly connected to the upper side of the rear of the inner surface of the filter box. A diverter seat is fixedly connected to the top of the nozzle, and a water supply pipe is fixedly connected to the top of the diverter seat. A water pump is fixedly connected to the outer side of the right end of the water supply pipe, and a water storage tank is fixedly connected to the bottom of the water pump. The water supply pipe passes through the upper side of the inner surface of the water storage tank.

[0011] Preferably, the wastewater filtration mechanism includes a flow guide funnel, which is fixedly connected to the middle of the rear side of the inner surface of the filter box. A filter plate is provided at the lower end of the flow guide funnel, and the filter plate is installed on the lower side of the rear part of the inner surface of the filter box.

[0012] Preferably, a scraper is slidably connected to the top of the filter plate, and an electric telescopic rod is symmetrically fixedly connected to the front end of the scraper. A sealing seat is symmetrically fixedly connected to the lower side of the inner surface of the ventilation baffle located at the rear end. Two electric telescopic rods are respectively installed on the inner surface of the two sealing seats. A control box is installed at the front end of the two electric telescopic rods. The control box is fixedly connected to the lower side of the front of the inner surface of the filter box.

[0013] Preferably, a sedimentation tank is provided at the lower end of the filter plate, and the sedimentation tank is fixedly connected to the rear side of the bottom of the filter box. A slope plate is fixedly connected to the front side of the upper part of the sedimentation tank. A grading baffle is symmetrically arranged at the lower end of the slope plate. The height of the grading baffle increases sequentially from back to front. The grading baffle is fixedly connected to the lower side of the inner surface of the sedimentation tank. A discharge port is fixedly connected to the upper side of the front part of the inner surface of the sedimentation tank.

[0014] Preferably, each of the adsorption mechanisms includes a fixed outer frame, and a sealing ring is engaged with the upper side of the outer surface of the fixed outer frame. The outer surfaces of the sealing rings are fixedly connected to the upper side of the front of the inner surface of the filter box. An adsorption bag is engaged with the inner side of the fixed outer frame. A handle is symmetrically fixed with the upper side of the outer surface of the fixed outer frame near the sealing ring. A top cover is engaged with the top of the fixed outer frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This device utilizes a designed dust removal mechanism. Exhaust gas enters the exhaust gas filtration mechanism through the inlet pipe, where it is first sprayed with water to suppress dust. This water spraying effectively washes away large dust particles in the exhaust gas, rapidly reducing the dust content and preventing large dust particles from clogging or causing wear in subsequent filtration stages. This ensures the stable operation of the entire filtration device. The wastewater after dust suppression at the dust removal mechanism undergoes preliminary filtration through filter plates. After filtration to a certain extent, the dirt on the top of the filter plates is automatically scraped and cleaned by the movement of scrapers. The wastewater then enters the sedimentation tank and remains at the rear. When the water level rises to a certain height, it overflows to the front of the grading baffles for step-by-step sedimentation, resulting in relatively clean water flowing out of the outlet. This allows for water reuse and conserves water resources.

[0017] This device uses an adsorption mechanism to allow waste gas, after initial filtration at the dust removal mechanism, to enter the front of the waste gas filtration mechanism. The adsorption mechanism then performs secondary adsorption on impurities in the waste gas. Multiple adsorption mechanisms are installed to achieve multi-stage adsorption filtration. The adsorption mechanism, in combination with the dust removal mechanism, can improve the filtration effect of waste gas to a certain extent. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 As shown, a petrochemical waste gas filtration and diversion device includes a waste gas filtration mechanism 1, a dust removal mechanism 3 installed on the rear side of the inner surface of the waste gas filtration mechanism 1, a wastewater filtration mechanism 4 provided on the rear side of the bottom of the waste gas filtration mechanism 1, and adsorption mechanisms 6 symmetrically installed on the front side of the inner surface of the waste gas filtration mechanism 1.

[0027] In this embodiment, the dust removal mechanism 3 is installed on the rear side inside the exhaust gas filtration mechanism 1. This device mainly consists of the exhaust gas filtration mechanism 1, the dust removal mechanism 3, the wastewater filtration mechanism 4, and the adsorption mechanism 6. The exhaust gas filtration mechanism 1 is the main frame of the entire device, and multiple functional components are installed inside to gradually purify the exhaust gas. The dust removal mechanism 3 is located on the rear side of the inner surface of the exhaust gas filtration mechanism 1 and is responsible for spraying water to reduce dust in the incoming exhaust gas. The wastewater filtration mechanism 4 is located on the rear side of the bottom of the exhaust gas filtration mechanism 1 and is used to treat the wastewater generated by dust reduction. The adsorption mechanism 6 is symmetrically installed on the front side of the inner surface of the exhaust gas filtration mechanism 1 to perform secondary adsorption on the pre-filtered exhaust gas to further remove impurities. The filtered exhaust gas is discharged through the exhaust pipe 7.

[0028] For details, please refer to Figure 1 In this embodiment, the exhaust gas filtration mechanism 1 is provided with several air inlet pipes 2 at its rear end, the wastewater filtration mechanism 4 is provided with a collection box 5 at its front end, the exhaust gas filtration mechanism 1 is provided with an exhaust pipe 7 at its front end, a sealing cleaning door 8 is provided on the rear side of the inner surface of the exhaust gas filtration mechanism 1, and a sealing cleaning door 9 is provided on the left side of the inner surface of the wastewater filtration mechanism 4.

[0029] Further reference Figure 1 and Figure 2In this embodiment, the exhaust gas filtration mechanism 1 includes a filter box 101, and ventilation baffles 102 are symmetrically fixedly connected to the inner surface of the filter box 101.

[0030] Further reference Figure 1 and Figure 3 In this embodiment, the dust removal mechanism 3 includes a nozzle 301, which is fixedly connected to the upper side of the rear of the inner surface of the filter box 101. A diverter seat 302 is fixedly connected to the top of the nozzle 301, and a water supply pipe 303 is fixedly connected to the top of the diverter seat 302. A water pump 304 is fixedly connected to the outer side of the right end of the water supply pipe 303, and a water storage tank 305 is fixedly connected to the bottom of the water pump 304. The water supply pipe 303 passes through the upper side of the inner surface of the water storage tank 305.

[0031] Petrochemical waste gas enters the device through several inlet pipes 2 set at the rear end of the waste gas filtration mechanism 1. After entering, the waste gas first reaches the dust removal mechanism 3. The nozzle 301 of the dust removal mechanism 3 is fixed on the upper rear side of the inner surface of the filter box 101. The top of the nozzle 301 is connected to the diversion seat 302, and the diversion seat 302 is then connected to the water supply pipe 303. A water pump 304 is installed on the outer side of the right end of the water supply pipe 303. The water pump 304 draws water from the water storage tank 305 at the bottom and delivers the water to the nozzle 301 through the water supply pipe 303. The nozzle 301 sprays water onto the waste gas, directly and effectively flushing down large dust particles in the waste gas. This step can quickly reduce the dust content in the waste gas.

[0032] Further reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the wastewater filtration mechanism 4 includes a flow guide funnel 401, which is fixedly connected to the middle of the rear side of the inner surface of the filter box 101. A filter plate 402 is provided at the lower end of the flow guide funnel 401, and the filter plate 402 is installed on the lower side of the rear part of the inner surface of the filter box 101.

[0033] Further reference Figure 2 , Figure 4 and Figure 5 In this embodiment, a scraper 403 is slidably connected to the top of the filter plate 402. Electric telescopic rods 405 are symmetrically fixed to the front end of the scraper 403. Sealing seats 404 are symmetrically fixed to the lower side of the inner surface of the ventilation baffle 102 at the rear end. Two electric telescopic rods 405 are respectively installed on the inner surface of the two sealing seats 404. A control box 406 is installed at the front end of the two electric telescopic rods 405. The control box 406 is fixedly connected to the lower side of the front of the inner surface of the filter box 101.

[0034] After dust settling, the wastewater, carrying the washed-down dust, flows through the guide funnel 401 to the filter plate 402. The filter plate 402 performs preliminary filtration of the wastewater, intercepting larger particles of impurities. As filtration proceeds, dirt accumulates on the filter plate 402, affecting the filtration effect. At this time, the scraper 403 comes into play. When the dirt accumulates to a certain extent, the control box 406 controls the electric telescopic rod 405 to extend and retract, driving the scraper 403 to move on top of the filter plate 402 and automatically scrape off the dirt, thereby ensuring the filtration performance of the filter plate 402. When the dirt is pushed to the rear side of the top of the filter plate 402, it can be cleaned by opening the sealed cleaning door at point 8.

[0035] Further reference Figure 2 , Figure 4 and Figure 5 In this embodiment, a sedimentation tank 407 is provided at the lower end of the filter plate 402. The sedimentation tank 407 is fixedly connected to the rear side of the bottom of the filter box 101. A slope plate 408 is fixedly connected to the front side of the upper end inside the sedimentation tank 407. A grading baffle 409 is symmetrically arranged at the lower end of the slope plate 408. The height of the grading baffles 409 increases from back to front. The grading baffles 409 are all fixedly connected to the lower side of the inner surface of the sedimentation tank 407. A discharge port 410 is fixedly connected to the upper side of the front part of the inner surface of the sedimentation tank 407.

[0036] After preliminary filtration and cleaning, the wastewater enters the sedimentation tank 407. After entering the sedimentation tank 407, the wastewater remains at the rear. When the water level rises to a certain height, it overflows to the front of the grading baffles 409. The wastewater undergoes step-by-step sedimentation through several grading baffles 409. Larger particles of impurities settle first at the rear of the sedimentation tank 407. As the water flows forward, smaller particles settle in sequence, so that the water flowing out of the discharge outlet 410 is in a relatively clean state, realizing the reuse of water resources and achieving the effect of saving water resources.

[0037] Through the designed dust removal mechanism 3, the exhaust gas enters the exhaust gas filtration mechanism 1 through the air inlet pipe 2. First, the dust removal mechanism 3 sprays water to reduce dust. By spraying water, large dust particles in the exhaust gas can be directly and effectively flushed down, quickly reducing the dust content in the exhaust gas and preventing large dust particles from clogging or abrading subsequent filtration stages. This ensures the stable operation of the entire filtration device. The wastewater after dust removal by the dust removal mechanism 3 can be initially filtered by the filter plate 402. After filtration to a certain extent, the dirt on the top of the filter plate 402 can be automatically scraped and cleaned by the movement of the scraper 403. After the wastewater enters the sedimentation tank 407, it remains at the rear of the sedimentation tank 407. When the water level rises to a certain height, it overflows to the front of the grading baffle 409 for step-by-step sedimentation, so that the water flowing out from the discharge port 410 is relatively clean, thus reusing the water and saving water resources.

[0038] Example 2: Based on Example 1, this example adds an adsorption mechanism 6 for secondary filtration of petrochemical waste gas. By setting the adsorption mechanism 6, a multi-stage adsorption filtration effect can be achieved. The adsorption mechanism 6, in combination with the dust removal mechanism 3, can improve the filtration effect of waste gas to a certain extent.

[0039] For details, please refer to Figure 1 , Figure 2 and Figure 6 In this embodiment, each of the adsorption mechanisms 6 includes a fixed outer frame 601. A sealing ring 602 is snapped onto the upper side of the outer surface of the fixed outer frame 601. The outer surfaces of the sealing rings 602 are fixedly connected to the upper side of the front of the inner surface of the filter box 101. An adsorption bag 603 is snapped onto the inner side of the fixed outer frame 601. A handle 604 is symmetrically fixed onto the upper side of the outer surface of the fixed outer frame 601 near the sealing ring 602. A top cover 605 is snapped onto the top of the fixed outer frame 601.

[0040] After preliminary filtration by the dust removal mechanism 3, the exhaust gas enters the front of the exhaust gas filtration mechanism 1 and enters the adsorption mechanism 6. The outer surface of the sealing ring 602 is fixed to the upper front of the inner surface of the filter box 101, which serves as a seal. The inner side of the fixed outer frame 601 is engaged with the adsorption pack 603. The adsorbent inside the adsorption pack 603 adsorbs harmful substances in the exhaust gas onto the surface. Handles 604 are symmetrically arranged on the left and right sides of the outer surface of the fixed outer frame 601 near the upper side of the sealing ring 602, which facilitates the installation, disassembly and replacement of the adsorption mechanism 6. Since multiple adsorption mechanisms 6 are set, the exhaust gas achieves multi-stage adsorption filtration when passing through these adsorption mechanisms 6. The multiple adsorption mechanisms 6 cooperate with the dust removal mechanism 3 to further improve the filtration effect of the exhaust gas, remove as many impurities as possible from the exhaust gas, and make the purified exhaust gas meet the emission requirements.

[0041] The adsorption pack 603 in this solution can be an activated carbon or silica gel adsorption pack from the existing technology. It uses the adsorption method to adsorb harmful substances in the waste gas onto the surface using the adsorbent.

[0042] The control box 406 in this solution can be a controller that includes an outer casing and an electric telescopic pole, which is a technology that includes an outer casing and an electric telescopic pole. The controller can be the Dongyuxiang YMD602, model: YMD602, voltage range: supports 12V / 24V / 36V / 48V, output power: 38W, load capacity 2000N, built-in limit switch, supports travel control, and supports communication with PLC.

[0043] Since the above devices are all very mature products in the prior art, they will not be described in detail in this application.

[0044] It should be noted that the specific installation method, circuit connection method and control method of the control box 406 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
