Description

Technical Field

[0001] This utility model relates to the field of pulse dust removal technology, and in particular to a pulse electrostatic drying dust collector. Background Technology

[0002] Industrial production processes generate large amounts of dust and harmful gases, posing serious threats to the environment and human health. Dust collectors are needed to remove these pollutants. A dust collector is an industrial device used to separate suspended particulate matter from gases. Its core function is to remove solid impurities from gases through physical or mechanical means, thereby purifying the gases and protecting the environment or equipment.

[0003] Working principle of pulse electrostatic dryer: When dust-laden gas passes through the electric field, the corona electrode ionizes the air to generate ions. After the dust particles are charged, they migrate to the dust collecting electrode and attach. When the dust collection electrode's dust accumulation resistance reaches a preset threshold, the pulse valve is triggered to open and compressed air is generated through the blow holes to form a reverse airflow that shakes off the dust. The shaken-off dust falls into the collection chamber and is cleaned periodically.

[0004] However, pulse-type electrostatic precipitators still face many problems during use. After collecting dust, the equipment usually stores it directly without a filtration device. The collected dust may contain large particles or impurities, which increases the difficulty of subsequent processing and use and is not conducive to the reuse of dust. Utility Model Content

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a pulse electrostatic drying dust collector, including a support frame 1, a box 2 fixedly installed on the top of the support frame 1, a corona electrode 11 fixedly connected to the bottom of the inner cavity of the box 2, and a dust collecting electrode 12 fixedly connected to the inner cavity wall of the box 2. When the corona electrode 11 is energized, it generates high voltage static electricity, which charges the dust, and the dust collecting electrode 12 adsorbs the dust. A plurality of nozzles 10 are fixedly connected to the inner cavity wall of the box 2, and a plurality of air nozzles are connected to the outer surface of the nozzles 10.

[0030] The solenoid valve is activated to spray high-pressure gas from the gas storage tank 9 through the nozzle on the nozzle 10 onto the dust collecting electrode 12. The pulse pressure is 0.4-0.5 MPa, and each spray lasts for 0.1-0.2 seconds. The high-pressure gas blows the dust adsorbed on the dust collecting electrode 12 downwards into the recycling hopper 13. The recycling hopper 13 is fixedly connected to the bottom of the housing 2. A first mounting groove is opened through the outer surface of the recycling hopper 13. A first filter screen 14 is slidably connected to the inner wall of the first mounting groove. A recycling box 7 is fixedly connected to the side of the recycling hopper 13 away from the housing 2. A second mounting groove is opened through the outer surface of the recycling box 7. A mounting frame 16 is slidably connected to the inner wall of the second mounting groove.

[0031] Example 2

[0032] Reference Figure 1-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a second filter screen 17 is fixedly installed on the inner wall of the mounting frame 16, the first filter screen 14 has a pore size of 100-150μm, the second filter screen 17 has a pore size of 20-50μm, a first locking block is fixedly connected to both sides of the second mounting groove, a first locking groove 18 is opened through the outer surface of the mounting frame 16, the inner wall of the first locking groove 18 is slidably connected to the outer wall of the first locking block, the mounting frame 16 can slide on the locking block through the first locking groove 18 and be pulled out from the recycling box 7 for cleaning, a third mounting groove is opened through the outer surface of the recycling box 7, and a collection box 15 is slidably connected to the inner wall of the third mounting groove;

[0033] The second locking block is fixedly connected to both sides of the third mounting slot. The outer surface of the collection box 15 is provided with a second locking groove 19. The inner wall of the second locking groove 19 is slidably connected to the outer side of the second locking block. The outer surface of the box 2 is fixedly connected to a mounting plate. The top of the mounting plate is fixedly installed with a vacuum pump 6. The input end of the vacuum pump 6 is connected to a vacuum pipe 5. The end of the vacuum pipe 5 away from the vacuum pump 6 is connected to a vacuum box 3. When the vacuum pump 6 is started, the dust-laden gas is sucked in through the vacuum box 3. The dust-laden gas is first heated by the heating pipe 4 installed in the vacuum box 3 to dry it. Then it is transported to the dust outlet pipe through the vacuum pipe 5 and sent into the box 2.

[0034] Several heating tubes 4 are fixedly installed on the inner wall of the dust collection box 3. The working temperature of the heating tubes is controlled between 80-120℃ to avoid the dust resistivity change due to excessive temperature, which would affect the electrostatic adsorption effect. The dust-laden gas is heated by the heating tubes 4 installed in the dust collection box 3 to dry it for subsequent processing. The output end of the dust pump 6 is connected to the dust outlet pipe, which is connected to the outer surface of the box 2. The outer surface of the box 2 is fixedly installed with the mounting base 8. The top of the mounting base 8 is fixedly connected to the air tank 9. The outer surface of the air tank 9 is connected to the air outlet pipe. A solenoid valve is installed in the air outlet pipe. When the solenoid valve is activated, the high-pressure gas in the air tank 9 is sprayed through the nozzle on the spray pipe 10 to the dust collecting electrode 12. The high-pressure gas blows off the dust adsorbed on the dust collecting electrode 12. The end of the air outlet pipe away from the air tank 9 is connected to the spray pipe 10.

[0035] The remaining structure is the same as that in Example 1.

[0036] During use, the dust pump 6 is started to draw in dust-laden gas through the dust collection box 3. The dust-laden gas is first heated and dried by the heating tube 4 installed in the dust collection box 3, and then transported to the dust outlet pipe through the dust collection pipe 5 and sent into the box 2. After the corona electrode 11 is energized, it generates high voltage static electricity, which charges the dust. The dust collection electrode 12 adsorbs the dust. The solenoid valve is started to spray the high pressure gas in the gas storage tank 9 through the nozzle on the spray pipe 10 onto the dust collection electrode 12. The high pressure gas blows the dust adsorbed on the dust collection electrode 12 down into the recovery hopper 13. After being filtered by the first filter screen 14 in the recovery hopper 13, it continues to fall down into the recovery box 7. Larger particles are intercepted on the upper surface of the first filter screen 14. The first filter screen 14 is designed to be pulled out for easy cleaning and replacement of filter screens with different pore sizes. Then the dust is filtered a second time by the second filter screen 17 of the mounting frame 16. The filtered dust falls into the collection box 15, realizing the filtration and recovery of dust.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
