Description

Technical Field

[0001] The present application belongs to the technical field of dust removal equipment, and in particular, relates to an oil-water mixed steam cleaning device. Background Art

[0002] Oil-based cuttings are special wastes generated during oil and gas drilling operations, and their treatment and disposal has become a key link restricting the green development of the industry. This substance is mainly formed by the mixture of drilling fluid and formation cuttings, and generally contains mineral oils, organic additives and pore water, and the rest are solid particles with complex particle size distribution. With the increasingly stringent global environmental protection regulations, my country's "National List of Hazardous Wastes" has listed it as HW08 hazardous waste, requiring the technical standards of oil phase recovery rate ≥ 95% and tailings oil content ≤ 0.3%. When treating oil-based cuttings, oil and water need to be separated. During the separation process, the process is to first convert the oil, organic matter and water in the cuttings into high-temperature steam, and then re-condense the high-temperature oil-water steam into an oil-water mixture. In the actual production process, there will be a lot of dust in the oil-water mixed steam, resulting in dust affecting condensation separation in the subsequent process, and the high-concentration dust cannot be effectively removed.

[0003] When mixed vapor with high dust concentration enters the condensation system, it will cause the mixed vapor to be difficult to condense and separate, and ordinary separation equipment will not be effective. This is because the temperature of the mixed oil vapor is relatively high, generally exceeding 350°C, which is flammable and explosive, and the dust in it has a high viscosity during separation, so there are certain difficulties in separation. At present, there is no better equipment to remove and separate high-concentration dust in high-temperature (350°C) oil-water mixed vapor, and the existing equipment cannot effectively remove high-concentration dust in oil-water mixed vapor.

[0019] The following will be combined with the accompanying drawings corresponding to the specific implementation methods of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. The following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection. The described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, various different configurations can be used to arrange and design. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The present application is described below with reference to the accompanying drawings and specific embodiments: Please refer to Figure 1In the first aspect of the present application, an oil-water mixed steam cleaning device is provided, which includes a main body 100 and a dust collection assembly 200. The main body 100 provides a container space for processing oil vapor. The main body 100 is provided with a clean chamber 101 and an air inlet channel 102 and an exhaust channel 103 independently connected to the clean chamber 101. The air inlet channel 102 and the exhaust channel 103 are responsible for the entry and exhaust of oil vapor respectively. The clean chamber 101 is a space for mainly processing dust in the steam. The steam enters the clean chamber 101 from the air inlet channel 102 and then is discharged from the exhaust channel 103. The dust collection assembly 200 is arranged in the clean chamber 101 and occupies the flow cross section of the airflow in the clean chamber 101, ensuring that the steam only passes through the dust collection assembly 200, so as to fully capture the dust in the steam. The dust collection assembly 200 includes an air distribution plate 210 with ventilation holes, multiple first elastic members 220, multiple hanging plates 230, multiple collecting brushes and connecting rods 250. The air distribution plate 210 is connected to the main body 100 and is located in the clean chamber 101. The air distribution plate 210 is plate-shaped and has ventilation holes. The edge of the air distribution plate 210 is welded or screwed to the inner wall of the main body 100. The two ends of the multiple first elastic members 220 are respectively connected to the air distribution plate 210 and the hanging plates 230. The first elastic member 220 adopts a high-temperature resistant spring, such as a stainless steel spring, which can withstand the action of steam. The top end of the first elastic member 220 is connected to the bottom of the air distribution plate 210, and the bottom end of the first elastic member 220 is welded and fixed to the top side of the hanging plate 230. The multiple hanging plates 230 are arranged at intervals in the clean chamber 101, and the hanging plates 230 are preferably equidistant from each other, thus forming the approximate range of the dust collection assembly 200.

[0021] Please refer to Figure 2 The collecting brush is provided with a plurality of fiber bristles 242 for attaching particles, and the fiber bristles 242 are closely arranged. The plurality of collecting brushes are fixed to the two sides of the hanging plate 230 by welding, plugging or other connection methods, and the intervals between adjacent hanging plates 230 are filled with collecting brushes, so that the fiber bristles 242 can fill the space between the hanging plates 230 and the hanging plates 230, and the hanging plates 230 and the collecting brushes occupy the flow cross section of the airflow in the cleaning chamber 101, and the fiber bristles 242 can fill the entire flow cross section. The surface is ensured to pass through between the fiber bristles 242, so that the vent position corresponds to the capture brush, and the steam airflow can fully contact the fiber bristles 242. The connecting rod 250 is connected to multiple hangers 230, and the spaced positions of the connecting rod 250 are respectively provided with connection points of different hangers 230. The multiple hangers 230 are connected to the connecting rod 250 by hinges, plugs or other connection methods. The main body 100 is provided with a rod hole passing through the connecting rod 250, and one end of the connecting rod 250 is connected to the main body 100 through the rod hole.

[0022] During the heating process of oil-based rock cuttings in an oxygen-free environment, in order to ensure that the material is heated evenly, the distillation device is constantly tumbling or rotating during the heating process to stir the internal material to be heated evenly, so that a large amount of fine rock cuttings dry residue after heating and drying is suspended in the distillation furnace, and the high-concentration high-temperature dust forms a vapor mixture with the high-temperature oil-water mixed vapor that has been formed in the furnace. It is continuously extracted to the condensation device for cooling along with the oil-water mixed vapor. During the cooling process, this part of the dust is again wrapped by part of the condensed oil as a condensation nucleus to form a viscous sludge liquid. After a long period of precipitation, the clearer mixed liquid at the top of the sedimentation tank is further distilled and refined by the distillation tower to further form an oil-water mixed vapor and separate some of the dust. The viscous sludge at the bottom of the sedimentation tank is returned to the raw material again and separated by high-temperature distillation again. However, in the prior art, there will be a large amount of dust in the oil-water mixed vapor, resulting in dust affecting condensation separation in the subsequent process, and the high-concentration dust cannot be effectively removed. When mixed vapor with high dust concentration enters the condensation system, it will cause the mixed vapor to be difficult to condense and separate. This is due to the high temperature and flammable and explosive characteristics of the mixed oil vapor. The temperature of the mixed oil vapor generally exceeds 350°C, which is flammable and explosive, and is not easy to handle. In addition, the viscosity of the dust in it is relatively large during separation, so there are certain difficulties in separation. Ordinary separation equipment is not effective, and there is currently no better equipment to remove and separate high-concentration dust.

[0023] The present application captures dust by setting a dust collecting component 200 in the clean chamber 101 between the air inlet channel 102 and the exhaust channel 103. By occupying the flow cross section of the airflow in the clean chamber 101, after the airflow enters from the air inlet channel 102, the area of ​​the dust collecting component 200 in the clean chamber 101 can only pass through the dust collecting component 200, ensuring that the dust collecting component 200 can fully capture the steam. Specifically, the oil-water mixed steam is smoothly passed into the collecting brush between the hanging plates 230 through the air distribution plate 210, and the high-concentration dust in the steam is blocked by the fiber bristles 242 on the collecting brush, thereby producing a collecting effect, and the space between adjacent hanging plates 230 is filled with dust. The cloth collecting brush can fill the space occupied by the entire dust collecting assembly 200, effectively collect high-concentration dust, and the steam carrying dust can effectively stay on the fiber bristles 242 when passing through the fiber bristles 242. Since the space of the cleaning chamber 101 is large, the flow rate of the steam is greatly slowed down. When the flow rate drops significantly, a large amount of dust is more easily blocked by the fiber bristles 242. On the other hand, under the action of the steam, the hanging plate 230 and the first elastic member 220 vibrate to a certain extent. When the dust blocked by the fiber bristles 242 accumulates to a certain amount, it helps the dust to fall, so that the dust with a large viscosity can be effectively cleaned and dropped after accumulation. Therefore, when the oil-water vapor passes through, the present application separates a large amount of dust from the vapor, can effectively remove the high-concentration dust in the oil-water mixed vapor, and improves the processing efficiency of the oil-water mixed vapor.

[0024] Please refer to Figure 1In some embodiments, a partition 130 connected to the main body 100 is provided in the main body 100. The partition 130 can be a metal plate welded and fixed in the main body 100, or a detachable plate connected to the inner wall of the main body 100 by bolts. The top of the partition 130 is connected to the top wall in the main body 100. The partition 130 is arranged between the air intake channel 102 and the exhaust channel 103, and blocks the direct connection position between the air intake channel 102 and the exhaust channel 103. The partition 130 extends into the clean cavity 101 and coincides with the corresponding position of the hanging plate 230. The bottom end of the partition 130 extends all the way to the middle of the clean cavity 101. The partition 130 is spaced from the hanging plate 230 so that the airflow forms an opposite flow direction in the clean cavity 101. The horizontal corresponding positions of the partition 130 and the hanging plate 230 coincide, and the partition 130 covers the vertical corresponding range of the hanging plate 230. The partition 130 divides the clean chamber 101 into two left and right parts, and the two parts are connected at the bottom of the partition 130. As shown in the figure, the chamber on the left side of the partition 130 is a coarse dust settling area. The design of this special flow path allows the high-concentration oil-water mixed vapor dust-containing gas to enter the dust settling area from the air inlet channel 102, and the flow velocity is rapidly reduced to 1 / 20-1 / 10 of the velocity in the pipeline of the air inlet channel 102. Some large dust particles or fine dust with strong adhesion are separated from the gas for primary sedimentation separation due to the significant drop in flow velocity and the blocking effect of the fiber brush 242 on the dust collector.

[0025] Please refer to Figure 2 In some embodiments, the spacing between the multiple collection brushes gradually increases along the direction in which the airflow enters the vent, such as Figure 1The spacing between the vertically adjacent collecting brushes near the upper end is small, and the spacing gradually increases along the vertical downward airflow direction. The spacing between the vertical collecting brushes near the lower end is larger. The collecting brush includes a brush rod 241 and fiber bristles 242 that are resistant to more than 1000°C. The use of high-temperature resistant fiber bristles can ensure that the dust is effectively cleaned and collected, and the cleaning effect is maintained for a long time. The brush rod 241 is the basis for installing the fiber bristles 242. The brush rod 241 can be made of a stainless steel column or a rod-shaped structure formed by winding multiple strands of high-temperature resistant steel wires. The fiber bristles 242 are made of materials that are resistant to more than 1000°C, such as aluminum silicate ceramic fibers, and other materials that are resistant to more than 1000°C, such as silicon carbide, aluminum oxide, nickel-based alloys, etc., can also be made into fibrous bristles. The fiber bristles are made of corrosion-resistant materials and have certain anti-corrosion properties. The above-mentioned materials themselves also have corrosion resistance, which can solve the problems of high temperature resistance and corrosion resistance. The arrangement of multiple fiber bristles 242 is similar to that of a brush. Multiple fiber bristles 242 are arranged in multiple rows and columns along the axial direction of the brush rod 241 and are recorded as a group. The arrangement of multiple rows and columns increases the capture surface area and improves the capture effect. Multiple groups of fiber bristles 242 are arranged along the circumference of the brush rod 241. The multiple groups of fiber bristles 242 are distributed along the circumference of the brush rod 241, so that the airflow can fully contact the bristles when passing through, further improving the capture efficiency. The end of the brush rod 241 is connected to the hanging plate 230, such as the end of the brush rod 241 is inserted into the socket set on the surface of the hanging plate 230, so as to form a match.

[0026] In some embodiments, a vibration device 300 is further included, which is arranged outside the main body 100. The vibration device 300 adopts a high-frequency electromagnetic vibrator, and other conventional vibration equipment can also be adopted. The vibration force is provided by the vibration device 300, and the vibration device 300 is fixed to the outer wall of the main body 100 by bolting; the output end of the vibration device 300 is connected to the connecting rod 250 and can drive the connecting rod 250 to move axially, such as the output end vibration rod of the high-frequency electromagnetic vibrator is connected to the connecting rod 250 through a coupling, and the connecting rod 250 moves back and forth along the axial direction for a short distance under its drive, and the connecting rod 250 is used to transmit high-frequency vibration, so that a movable connection is formed between the connecting rod 250 and the main body 100. In order to maintain a tight seal, it can be A dynamic sealing structure is arranged at the periphery where the connecting rod 250 contacts the main body 100, such as sealing materials such as asbestos, graphite, asbestos packing, etc., to ensure that there is no leakage of steam; the connecting rod 250 is hinged to all the hanging plates 230, such as hinge holes are arranged at the bottom ends of the hanging plates 230, and the connecting rod 250 is arranged on one side or both sides of the hanging plates 230, and a pin connection method is adopted, such as a hinge bolt 251, so that the connecting rod 250 and multiple hanging plates 230 are hinged, and a second elastic member 260 is arranged between the end of the connecting rod 250 and the partition 130, and the second elastic member 260 also adopts a high temperature resistant spring, which is arranged horizontally, one end of the spring is welded and fixed to the partition 130, and the other end is also welded and fixed to the end of the connecting rod 250.

[0027] After dust is collected for a period of time, a large amount of dust will adhere to the aluminum silicate ceramic fiber, increasing the system resistance and reducing the collection effect. The high-frequency electromagnetic vibrator is started, and the high-frequency reciprocating motion of the connecting rod 250 drives the fiber bristles 242 on the hanging plate 230 to vibrate, which plays a role in cleaning the dust on the fiber bristles 242. In the high-frequency vibration, in order to prevent the risk of explosion or internal combustion caused by sparks generated by local friction, the connecting rod 250 and the hinge are made of pure copper to play an explosion-proof role. At the same time, the first elastic member 220 and the second elastic member 260 can not only play a certain supporting role, but also increase the amplitude. The first elastic member 220 and the second elastic member 260 can be made of pure copper.

[0028] Please refer to Figure 3 In some embodiments, the air distribution plate 210 includes an air distribution frame 211 and a folding plate strip 212. The air distribution frame 211 is connected between the inner wall of the main body 100 and the partition 130. The outer edge of the air distribution frame 211 is fixed to the partition 130 and the inner wall of the main body 100 by welding. The air distribution frame 211 is horizontally arranged. The air distribution frame 211 has a ventilation hole that is through-set. The airflow enters the settling area from the ventilation hole. A plurality of folding plate strips 212 are arranged at intervals and connected to the air distribution frame 211. It can be fixed by welding, so that a grate shape is formed with the air distribution frame 211, and the gaps between adjacent folding strips 212 form grate seams. The air distribution frame 211 and the folding strips 212 are made of stainless steel. The folding strips 212 are set as an inclined surface for guiding flow on the air intake side. For example, the top of the folding strips 212 is set to a wedge shape. This can prevent dust from accumulating and forming carbon deposits that block the grate seams. The inclined surface also plays a guiding role, so that the incoming airflow is more evenly distributed when it flows directly downward.

[0029] Please refer to Figure 4In some embodiments, it also includes a fixed flower plate 410, a plurality of steam filter components and a blowing component 500 located in the cleaning chamber 101. The fixed flower plate 410 is connected between the partition 130 and the inner wall of the main body 100, so that the airflow passes through the capture brush and then passes through the steam filter component in the opposite flow direction. The outer edge of the fixed flower plate 410 is fully welded to the inner wall of the main body 100 and the side wall of the partition 130. The fixed flower plate 410 is provided with a plurality of mounting ports 411, and a plurality of steam filter assemblies are fixed to the mounting ports 411. For example, the steam filter assembly 400 is provided with a connecting hole, and the fixed flower plate 410 is connected with a screw 412. When the screw 412 corresponds to the connecting hole, a nut is used to fix the steam filter assembly 400 to the fixed flower plate 410, and the outlet of the steam filter assembly 400 is opposite to the mounting port 411, and the air outlet of the spray assembly 500 extends to the mounting port 411, so that the gas discharged from the steam filter assembly 400 and coming out of the mounting port 411 can be sprayed through the spray assembly 500. The spray assembly 500 adopts a device that can provide blowing to avoid the discharge of residual dust. The steam filter assembly is a filtering device with a plurality of filter holes, which can filter the dust-carrying steam for a second time, thereby significantly improving the dust separation effect.

[0030] In traditional industries, the most effective way to separate high-concentration dust from gas is to use a pulse bag filter. Currently, the maximum instantaneous temperature that the flexible filter material used in pulse bag filters can withstand shall not exceed 260°C, and the long-term safe use temperature shall not exceed 240°C. The maximum temperature of the pulse valve diaphragm used for cleaning shall not exceed 230°C, which is much lower than the high-temperature steam temperature of oil-based cuttings of 350-450°C. When oxygen leaks into the high-temperature oil-water vapor system and spontaneous combustion occurs, the local temperature inside is close to 600°C, and the current traditional filter material cannot adapt at all. Some manufacturers' newly developed ceramic filter cartridges 420 or stainless steel metal sintered membrane filter materials can be used at 350°C, but the filter bags made of such materials have high thermal conductivity, and the heat dissipation is fast during the start-up and shutdown of the equipment, which increases the temperature difference between the oil and water vapor, and easily causes the oil phase medium to exhibit semi-fluid properties. The dust adhesion coefficient increases by 3-8 times, and the pressure difference growth rate of the dust collector increases by 2-3 times compared with conventional working conditions. Since the filter cartridge 420 made of such filter material is inelastic, the filtering effect is greatly reduced and it cannot operate stably for a long time. The filter materials are all disposable products with short service life, high scrap rate and high cost. It is difficult for general enterprises to afford it, which is not convenient for reducing the overall disposal cost of the oil-based cuttings industry and has no practical value for promotion.

[0031] Please refer to Figure 5In some embodiments, the above-mentioned filtering device adopts a filter cartridge 420, and the filter cartridge 420 includes an inner layer 421 and an outer layer 422, and a filter material 423 substrate provided in the gap between the inner layer 421 and the outer layer 422. The filter material 423 is a cylindrical layered structure, and the inner layer 421 and the outer layer 422 protect the filter cartridge 420 of the filter material 423, which solves the problem that the tensile strength of aluminum silicate ceramic fiber is low and is not conducive to pulse jet cleaning. Limited by the high-temperature oil-water vapor temperature and dust-containing characteristics of oil-based rock cuttings, the material and structural form of the filter material 423 currently used for high temperature and normal temperature are difficult to meet the requirements. This embodiment selects high temperature and corrosion-resistant aluminum silicate ceramic fiber as the filter material 423 substrate to make a ceramic fiber paper filter bag, so that the dust permeability does not exceed 10mg / Nm3 under 500Pa negative pressure suction. To ensure that the tear strength of the filter bag meets the use requirements during 0.6MPa jet cleaning. On the outside of the filter bag, a steel wire mesh with an aperture of 20-30 microns is used to make an outer cylinder to cover the outside of the filter bag, and a 5-10mm screen is used to make an inner cylinder to be placed inside the filter bag to ensure that the filter bag does not expand excessively to the outside during high-pressure spray cleaning, and does not shrink excessively to the inside after cleaning, to ensure that the tear strength of the manufactured filter bag meets the use requirements. The filter cartridge 420 is made of high-temperature resistant material, and multiple filter cartridges 420 pass through the installation port 411 of the fixed flower plate 410. The inner and outer cylinder flanges overlap and press to fix and seal the middle filter bag, and then are fixed and locked by bolts on the flower plate holes. The high-temperature oil, water vapor and dust-containing gas pass through the outer layer 422 steel wire mesh and are filtered by the middle ceramic fiber filter material 423, and the clean gas is extracted out of the device.

[0032] Oil and water vapor and sulfur / chlorine-containing dust form an acidic microenvironment, which produces dew point corrosion in the temperature range of 120-200℃, with a typical corrosion rate of 0.5-2mm / year. The service life of 304 stainless steel is shortened by 40%-60% in this environment. The chemical composition of oil-based cuttings is complex, the chloride ion content is high, and it is highly corrosive to stainless steel materials, so stainless steel filter material 423 cannot be considered. Taking the above factors into consideration, this application has multiple characteristics such as corrosion resistance, explosion-proof, high temperature resistance, high oil and water vapor separation efficiency, and energy saving. It solves the bottleneck problem of the oil-based cuttings disposal industry well, and can scale up the disposal scale of a single device. Compared with the current mainstream process flow at the same scale, it has fewer equipment, less investment, simpler process, less space, and lower unit disposal cost.

[0033] Please refer to Figure 6In some embodiments, it also includes a linear drive device 610, a connecting rod 250 and a scraper 630. The linear drive device 610 is installed outside the main body 100. The linear drive device 610 adopts a linear servo motor and is installed on the top of the main body 100 by bolts. A rod hole is opened on the top of the main body 100. After the connecting rod 250 passes through the rod hole, asbestos, graphite, etc. are used for dynamic sealing. One end of the connecting rod 250 is connected to the output end of the linear servo motor through a coupling, and the other end of the connecting rod 250 is welded and fixed to the scraper 630. The scraper 630 is located in the cleaning chamber 101. The scraper 630 is composed of a multi-layer equidistant metal frame, and a plurality of scrapers 631 are installed between the frames. The scraper 631 adopts a ring structure made of copper sheets and is connected to the servo motor at the top of the main body 100 through the connecting rod 250. Driven by the motor, it can move up and down in the vertical direction. Each scraper 631 corresponds to a filter device. The scraper 631 is sleeved on the outer periphery of the filter device, that is, the annular scraper 631 is arranged on the outer wall of the filter cartridge 420. In this way, the scraper 631 will scrape off the dust adhering to the metal wire mesh of the outer layer 422 of the filter cartridge 420, reduce the filtration resistance of the filter cartridge 420, and solve the problems of dust accumulation outside the filter cartridge 420, difficulty in cleaning, and short equipment service life; the scraper 631 is made of copper skin, which has a certain flexibility and a lower hardness than the steel metal wire mesh filter cartridge 420. It does not damage the metal wire mesh when scraping off the dust adhesion layer. The flexibility can adjust part of the assembly error. The copper skin solves the problem of internal sparks caused by friction and impact, which may cause combustion and explosion, and ensures that no sparks are generated when the metal layer surface is rubbed to cause safety risks.

[0034] In some embodiments, the spray assembly 500 includes an air supply device 510, a vent valve 520 and a spray conduit 530. The air supply device 510 is located outside the main body 100. The air supply device 510 uses a nitrogen heating gas storage tank. Nitrogen is used as a dust cleaning gas source to solve the problems of oxygen enrichment and prevention of combustion and explosion. The tank body is fixed to the outer wall of the main body 100 through a conventional flange or coupling and bolts. It is a conventional installation method. The nitrogen heating gas storage tank is a device for providing heated nitrogen, and its outlet is connected to the spray conduit. The nozzle 510 is connected to the filter cartridge 420 through the nozzle 530. The nozzle 510 is connected to the filter cartridge 420 through the nozzle 530. The joint at the connection ensures sealing. The other end of the spray duct 530 extends to the installation port 411 and branches out a plurality of nozzles. The nozzles are aligned with each installation port 411. The nozzles extend a section into the installation port 411 and are placed in the filter cartridge 420. The vent valve 520 is installed on the spray duct 530. The vent valve 520 adopts a high-temperature electromagnetic pulse valve, which can provide nitrogen to the outlet of the filter cartridge 420 at a high frequency. The discharged nitrogen is used to purge the discharged steam and leave the residual dust in the filter cartridge 420. In some embodiments, a discharger 700 is further included, which is arranged on the main body 100. The inlet of the discharger 700 is connected to the clean cavity 101. The inner wall of the main body 100 adjacent to the discharger 700 is set as an inclined surface. Specifically, the bottom of the clean cavity 101 of the main body 100 is set as a conical surface. After falling, the dust can flow along the conical surface to the inlet of the discharger 700. In this way, the dust discharge is controlled by the discharger 700. The discharger 700 adopts an air locking valve, such as a conventional air locking discharge valve.

[0035] In some embodiments, the main body 100 includes a shell 110 and an insulation layer 120, and the two ends of the shell 110 are respectively an air intake channel 102 and an exhaust channel 103. The shell 110 has a clean cavity 101, and the shell 110 is divided into an air intake section 111, a processing section 112 and an exhaust section 113. The air intake section 111 and the exhaust section 113 respectively adopt pipeline structures, and the processing section 112 adopts a container with a size larger than the air intake section 111 and the exhaust section 113, so that the clean cavity 101 has enough space to accommodate the dust collection assembly 200 and the steam filter assembly 400. The bottom of the processing section 112 is set to be funnel-shaped, and the above-mentioned discharger 700 is installed at the outlet of the funnel-shaped structure, so that the fallen dust can be quickly collected. The shell 110 is welded with chromium-molybdenum steel plates, and the outer wall or inner wall of the shell 110 is also provided with reinforcing ribs. For example, the outer wall of the shell 110 is reinforced in a "well" shape by using 14# channel steel on the outside to ensure that it does not deform under high temperature conditions to ensure the assembly accuracy of other components. The insulation layer 120 is coated on the outside of the shell 110. The insulation layer 120 is made of aluminum silicate fiber felt with an insulation thickness of not less than 200mm to minimize heat loss and ensure that the temperature of the high-temperature oil-water mixed vapor in the main body 100 is not lower than 350°C, so that the high-boiling point organic matter therein does not condense.

[0036] The working principle of this application is: The high-temperature oil-water mixed steam carries a large amount of dust. After the airflow enters the main body 100 through the air inlet channel 102, the airflow is relatively evenly distributed on the left side of the partition 130 ( Figure 1 (middle) flows from the grate gap of the air distribution plate 210 into the lower sedimentation area. The cross-sectional area of ​​the sedimentation area is 10-20 times the average cross-sectional area of ​​the airflow through the pipeline. The flow rate is greatly reduced and the residence time is prolonged. The large particles of dust carried by the airflow or entering the main body 100 are affected by the heat absorption of local components at the moment, causing part of the dust to liquefy and condense into small clumps due to the lowering of the boiling point of organic matter. When it flows through the fiber brush 242 for dust collection, it is captured, reducing the content of sticky dust carried by the airflow and reducing the filtering pressure of the filter cartridge 420 behind. After running for a period of time, the high-frequency electromagnetic vibrator can be started, and the connecting rod 250 can be used to drive the hanging plate 230 to shake, so that the accumulated dust on the fiber brush 242 falls to the inclined surface below and is discharged from the main body 100 through the bottom discharger 700. The high-temperature oil-water mixed dust-containing gas separated by sedimentation bypasses the partition 130 from the lower part of the sedimentation area and enters the right side of the partition 130 ( Figure 1 In the filtration area of ​​the filter cartridge 420, the filter enters the multiple filter cartridges 420 from the side of the filter cartridge 420, and the filtered dust falls into the lower ash hopper. The high-temperature oil-water mixed steam after purification and filtration is extracted from the outlet by the fan and enters the oil-water separator for condensation and separation. When the filter cartridge 420 filters the high-temperature gas containing residual dust, fine dust is continuously accumulated on the surface of the filter cartridge 420 and the filter material 423, resulting in increased filtration resistance. The pulse spray assembly 500 is used to introduce high-temperature and high-pressure pure nitrogen into the outlet of the filter cartridge 420 and the filter cartridge 420 for backblowing to ensure that the resistance of the filter cartridge 420 is within an appropriate range.

[0037] When the high-temperature oil, water vapor and dust-laden airflow contacts the metal wire mesh on the outer wall of the filter cartridge 420, a temperature difference will be caused between the two. There will be a condensation phenomenon at the microscopic level, which will increase the viscosity of the trace dust-laden gas and continuously adhere to the surface of the outer layer 422 of the filter cartridge 420. When high-pressure nitrogen is used for cleaning, the nitrogen temperature is lower than the internal high-temperature oil and water vapor temperature due to the temperature resistance of the pulse vent valve 520. The temperature difference will also occur during cleaning, which will increase the speed of dust adsorption on the surface of the filter cartridge 420. Pulse cleaning can remove some dust, but the pores of the metal wire mesh on the outer layer 422 of the filter cartridge 420 are large, and the pressure and flow rate of the jet cleaning after penetrating the filter material 423 layer are greatly reduced, making it difficult to completely clean the adhered dust, which will cause more and more dust adhesion on the outer layer 422 of the filter cartridge 420, and the filtration resistance will become larger and larger, affecting normal use. After the present application has been running for a period of time, according to the increase in resistance of the filter cartridge 420, the linear servo motor can be turned on online, and multiple groups of motors can run smoothly and synchronously, slowly lifting the movable scraper 630 to the corresponding stroke, and the copper scraper 631 on the scraper 630 will scrape off the thick dust adhering to the outside of the filter cartridge 420 to reduce the resistance of the filter cartridge 420, and clean the outer surface of the filter cartridge 420 online without stopping the machine.
