Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, in particular to a tubeless spray dust collector. Background Art

[0002] As we all know, a dust collector is a device used to treat smoke and mist in exhaust gas, and it has been widely used in the field of dust removal equipment. The existing tube bundle dust collector and mist eliminator is a device with the functions of gathering, capturing, and annihilating. It is an integrated device composed of a spray device, a guide flow rifling pipe seat, a first-level rectifier, a first-level turbofan separator, an isolation dust collector, a second-level gas rectifier, a second-level turbofan separator, a second-level gas rectifier, a third-level turbofan separator, a third-level gas rectifier, a droplet collection separator, and other components. After the exhaust gas is sprayed through the spray device, the tube bundle dust collector and mist eliminator mainly relies on the characteristics of the low-temperature saturated flue gas or the gas containing a large number of fine droplets at the upper part of the absorption tower, and utilizes a large number of fine droplets. Under the condition that the droplets follow the motion characteristics of the airflow, the probability of the dust particles colliding with the droplets increases. After the droplets and dust particles condense, they hit the turbofan blade collector under the principle of linear motion of the airflow; they gather into liquid under the action of the turbofan blades' redirection centrifugation and flow back to the bottom of the absorption tower under the action of their own gravity; this principle is used to capture and remove extremely small dust or coal dust and droplets in the flue gas or gas; it was found in use that due to the large number of rotating parts set in the tube bundle, dust will enter the rotating parts during dust removal and demisting, thereby affecting the normal operation of the rotating parts and the dust removal and demisting effect. The tube bundle needs to be frequently maintained, repaired, or replaced, and the continuous dust removal operation is not effective, which has certain limitations. Summary of the Invention

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a tubeless blowing dust collector with the following beneficial effects: the tubeless blowing dust collector blows the exhaust gas into the cyclone separation cylinder through the air inlet pipe, and passes the cold water into the cyclone separation cylinder through the water inlet pipe, and the exhaust gas and cold water are respectively sprayed out through the air jet pipe on the cyclone air pipe and the water spray pipe on the cyclone water pipe, so that the exhaust gas and cold water are fully in contact with each other in the cyclone separation cylinder, and the exhaust gas and cold water generate a cyclone in the cyclone separation cylinder. After the dust and mist in the exhaust gas meet the cold water, the mist is liquefied, and the dust dissolves and reacts with the water. In the process, under the action of cyclone, dust gathers at the bottom of cyclone separation cylinder and is discharged to the external sewage treatment system through the sewage pipe. The clean water at the top of cyclone separation cylinder flows back to the cold water source through the outlet pipe for reuse. After preliminary dust removal and demisting treatment, the exhaust gas enters the left cavity by opening the first and third connecting valves and closing the second and fourth connecting valves, and then enters the second working cavity after being dried by the silica gel desiccant layer in the left cavity. Alternatively, the exhaust gas enters the second working cavity after being dried by the silica gel desiccant layer in the left cavity, or enters the second working cavity after being dried by the silica gel desiccant layer in the left cavity. The exhaust gas enters the right chamber and is dried by the silica gel desiccant layer in the right chamber before entering the second working chamber. The silica gel desiccant layers in the left and right chambers serve as backup for each other, allowing the equipment to operate continuously without stopping when replacing the silica gel desiccant layer. The dried exhaust gas contains a small amount of dust. At this time, the exhaust gas enters the dust filter bag and is filtered by the dust filter bag before being discharged through the exhaust pipe. When the dust filter bag absorbs too much dust, the air bag is connected to the external compressed air source and started. At this time, the exhaust valve and the dust exhaust valve are closed, and the air bag will compress the air. The air source is blown into the dust filter bag, making the dust filter bag in a stretched state, and the movable plate moves downward, making the spring in a compressed state. Through intermittent air blowing, the air pressure of the dust filter bag is reduced, and the dust filter bag is in a contracted state. The spring expands and contracts, making the dust filter bag frequently stretched and contracted under the action of the spring, thereby separating the dust in the dust filter bag. At this time, the dust discharge valve and the cleaning valve are opened to discharge the dust collected at the bottom of the second working chamber. No complex rotating mechanism such as pipe bundles is required, which reduces subsequent maintenance and overhaul, and achieves better continuous dust removal and demisting effects.

The plurality of groups of dust filter bags 16 are fixedly connected to the movable plate 14, and the bottom ends of the plurality of dust filter bags 16 are provided with dust exhaust valves 27. The return plate 15 is fixedly arranged at the bottom of the second working chamber, and a plurality of groups of evenly distributed springs 28 are arranged between the return plate 15 and the movable plate 14. The air bag 17 is fixedly arranged at the right end of the second dust removal box 2.The output end of the air bag 17 extends into the upper part of the second dust removal chamber, and a dust cleaning pipe 29 is provided at the bottom of the second dust removal box 2, and a dust cleaning valve 30 is provided on the dust cleaning pipe 29. An exhaust pipe 31 is provided at the right end of the second dust removal box 2, and the exhaust pipe 31 is connected to the second working chamber, and an exhaust valve is provided on the exhaust pipe 31; the exhaust gas is blown into the cyclone separation cylinder 3 through the air inlet pipe 4, and the cold water is passed into the cyclone separation cylinder 3 through the water inlet pipe 5, and the exhaust gas and cold water are respectively ejected through the air injection pipe 18 on the cyclone air pipe 8 and the water injection pipe 19 on the cyclone water pipe 7, so that the exhaust gas and the cold water are fully in contact in the cyclone separation cylinder 3, and the exhaust gas and the cold water are in the cyclone separation cylinder 3, the dust and mist in the exhaust gas meet the cold water, the mist liquefies, and the dust dissolves in the water. Under the action of the cyclone, the dust gathers at the bottom of the cyclone separation cylinder 3 and is discharged to the external sewage treatment system through the sewage pipe 20. The clean water on the upper part of the cyclone separation cylinder 3 flows back to the cold water source through the outlet pipe 6 for reuse. After the preliminary dust removal and demisting treatment, the exhaust gas enters the left cavity by opening the first connecting valve 21 and the third connecting valve 24 and closing the second connecting valve 22 and the fourth connecting valve 25. Then, the exhaust gas enters the second working cavity after being dried by the silica gel desiccant layer 23 in the left cavity, or enters the second working cavity by closing the first connecting valve 21 and The third connecting valve 24 opens the second connecting valve 22 and the fourth connecting valve 25, allowing the exhaust gas to enter the right chamber, and then enter the second working chamber after being dried by the silica gel desiccant layer 23 in the right chamber. The silica gel desiccant layers 23 in the left chamber and the right chamber are standby for each other, so that the equipment can continue to operate without stopping when replacing the silica gel desiccant layer 23. The dried exhaust gas contains a small amount of dust. At this time, the exhaust gas enters the dust filter bag 16, is filtered by the dust filter bag 16, and is discharged through the exhaust pipe 31. When the dust filter bag 16 absorbs too much dust, the air bag 17 is connected to the external compressed air source and started, and the exhaust valve and dust exhaust valve 27 are closed at this time. The air bag 17 blows compressed air into the dust filter bag 16, stretching the dust filter bag 16. The movable plate 14 moves downward, compressing the spring 28. Intermittent air blowing reduces the air pressure in the dust filter bag 16, causing the dust filter bag 16 to contract. The spring 28 expands and contracts, causing the dust filter bag 16 to frequently stretch and contract under the action of the spring 28, thereby releasing dust from the dust filter bag 16. At this time, the dust discharge valve 27 and the dust cleaning valve 30 are opened to discharge the dust collected at the bottom of the second working chamber. This eliminates the need for complex rotating mechanisms such as pipe bundles, reduces subsequent maintenance and overhaul, and provides better continuous dust and mist removal effects.

[0025] The dust collector of the present invention is a ductless blowing dust collector, in which the third connecting pipe 11 and the fourth connecting pipe 12 extend into the output end of the second dust collecting box 2 and are provided with a check valve 32; the bottom of the second dust collecting box 2 is conical, and the bottom of the second dust collecting box 2 is provided with an oscillation motor 38; a spiral guide plate 33 is provided in the cyclone separation cylinder 3; a slide rail 34 is provided on the inner wall of the second dust collecting chamber, and the movable plate 14 can slide up and down on the slide rail 34; a limit plate 35 is fixedly provided on the top of the slide rail 34; a retractable sealing cloth 36 is provided between the movable plate 14 and the inner wall of the second dust collecting chamber; a first opening, a second opening and a third opening are provided at the front end of the first working chamber, the first opening is communicated with the lower chamber, the second opening is communicated with the left chamber, and the third opening is communicated with the right chamber, and a sealing door 37 is provided on the first opening, the second opening and the third opening; through the setting of the check valve 32, when the air bag 17 is inflated, the gas in the second working chamber can be effectively prevented from passing through the first working chamber. The three-way connecting pipe 11 or the fourth connecting pipe 12 refluxes, and through the bottom cone of the second dust removal box 2 and the setting of the oscillation motor 38, when discharging ash, by starting the oscillation motor 38, the bottom of the second dust removal box 2 is vibrated, so that the dust accumulated at the bottom of the second dust removal box 2 can be discharged more smoothly through the cleaning pipe 29. The setting of the spiral guide plate 38 can guide the water in the cyclone separation cylinder 3, so that the water in the cyclone separation cylinder 3 can better form a vortex. The setting of the slide rail 34 can make the movable plate 14 more stable during the up and down movement. The setting of the retractable sealing cloth 36 can seal the movable plate 14 and the inner wall of the second working chamber to prevent the exhaust gas from escaping through the gap between the movable plate 14 and the inner wall of the second working chamber. The setting of the first opening, the second opening and the third opening can be used to inspect and repair the equipment in the first working chamber, and the silica gel desiccant layer 23 in the left chamber and the right chamber can be replaced more conveniently.

[0026] During use, the exhaust gas is blown into the cyclone separation cylinder 3 through the air inlet pipe 4, and the cold water is introduced into the cyclone separation cylinder 3 through the water inlet pipe 5. The exhaust gas and the cold water are respectively sprayed out through the air injection pipe 18 on the cyclone air pipe 8 and the water injection pipe 19 on the cyclone water pipe 7, so that the exhaust gas and the cold water are fully in contact with each other in the cyclone separation cylinder 3. The exhaust gas and the cold water generate a cyclone in the cyclone separation cylinder 3. After the dust and mist in the exhaust gas meet the cold water, the mist is liquefied, and the dust is dissolved in the water. Under the action of the cyclone, the dust gathers at the bottom of the cyclone separation cylinder 3 and is discharged to the outside through the sewage pipe 20. In the sewage treatment system, the clean water on the upper part of the cyclone separation cylinder 3 is returned to the cold water source through the outlet pipe 6 for reuse. After the preliminary dust removal and demisting treatment, the exhaust gas is allowed to enter the left cavity by opening the first connecting valve 21 and the third connecting valve 24 and closing the second connecting valve 22 and the fourth connecting valve 25, and then enter the second working cavity after being dried by the silica gel desiccant layer 23 in the left cavity. Alternatively, the exhaust gas is allowed to enter the right cavity by closing the first connecting valve 21 and the third connecting valve 24 and opening the second connecting valve 22 and the fourth connecting valve 25, and then enter the right cavity after being dried by the silica gel desiccant layer in the right cavity. After the layer 23 is dried, it enters the second working chamber. The silica gel desiccant layers 23 in the left chamber and the right chamber serve as backup for each other, so that the equipment can continue to operate without stopping when replacing the silica gel desiccant layer 23. The dried exhaust gas contains a small amount of dust. At this time, the exhaust gas enters the dust filter bag 16, and is filtered by the dust filter bag 16 and discharged through the exhaust pipe 31. When the dust filter bag 16 absorbs too much dust, the air bag 17 is connected to the external compressed air source and started. At this time, the exhaust valve and the dust exhaust valve 27 are closed, and the air bag 17 blows the compressed air source into the dust filter bag 16 to remove the dust. The dust filter bag 16 is in a stretched state, and the movable plate 14 moves downward, so that the spring 28 is in a compressed state. By intermittently blowing air, the air pressure of the dust filter bag 16 is reduced, and the dust filter bag 16 is in a contracted state. The spring 28 is extended and retracted, so that the dust filter bag 16 is frequently stretched and contracted under the action of the spring 28, thereby separating the dust in the dust filter bag 16. At this time, the dust discharge valve 27 and the dust cleaning valve 30 are opened to discharge the dust collected at the bottom of the second working chamber. No complex rotating mechanism such as a tube bundle is required, which reduces subsequent maintenance and overhaul, and the continuous dust removal and demisting effect is better.By setting the check valve 32, when the air bag 17 is inflated, the gas in the second working chamber can be effectively prevented from flowing back through the third connecting pipe 11 or the fourth connecting pipe 12. By setting the bottom cone of the second dust removal box 2 and the oscillation motor 38, when discharging dust, the oscillation motor 38 can be started to vibrate the bottom of the second dust removal box 2, so that the dust accumulated at the bottom of the second dust removal box 2 can be discharged more smoothly through the cleaning pipe 29. By setting the spiral guide plate 38, the water in the cyclone separation cylinder 3 can be diverted to make the cyclone The water in the separation cylinder 3 forms a more stable swirl. The slide rails 34 ensure smooth vertical movement of the movable plate 14. The retractable sealing cloth 36 seals the movable plate 14 against the inner wall of the second working chamber, preventing exhaust gas from escaping through the gap between the movable plate 14 and the inner wall of the second working chamber. The first, second, and third openings allow for maintenance of equipment within the first working chamber and facilitate replacement of the silica gel desiccant layer 23 in the left and right chambers.
