Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to an environmentally friendly dust removal device with a breathing valve on the top of an ash storage silo. Background Technology

[0002] Sintered ash storage tanks are devices used to store sintered ash. They are typically made of robust metal materials and have good sealing properties to prevent sintered ash leakage and the ingress of external impurities. Their capacity can be designed according to actual needs to meet the storage requirements of different scales of sintered ash. The structural design of sintered ash storage tanks takes safety and stability into account, and can withstand certain internal pressures and external environmental influences. The breather valve at the top of the sintered ash storage tank plays a role in stabilizing the pressure inside the tank and protecting the tank. However, currently, when sintered ash is being transported into the tank, the increased pressure causes the breather valve at the top of the tank to open and release air, resulting in the discharge of sintered ash and causing environmental pollution.

[0003] For example, a Chinese patent document discloses an environmentally friendly dust removal device for a breather valve on the top of an ash storage silo (publication number: CN212188312U). Although this patent uses a dust monitor installed inside the dust collection hood to monitor dust concentration, and the dust monitor is interlocked with the dust extraction fan, when the dust monitor detects a dust concentration greater than 10mg / m³, the dust extraction fan automatically turns on, introducing the fumes from the breather valve into the brine pipe, where the dust mixes with the brine, thus avoiding environmental pollution.

[0004] However, in actual use, since the dust is adsorbed by mixing with the brine through gas transportation, but the gas rises quickly in the water, the dust adsorption is insufficient. Many fine dust particles are not adsorbed and are directly discharged from the brine, thus still causing environmental pollution problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, in practical applications, dust is adsorbed by mixing it with brine through gas transport. However, the gas rises rapidly in the water, resulting in insufficient dust adsorption. Many fine dust particles remain unadsorbed and are directly released from the brine, thus still causing environmental pollution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly dust removal device with a breathing valve on the top of a ash storage silo includes a storage silo body. A dust removal box is fixedly connected to the upper surface of the storage silo body. A rotating sleeve is mounted on the upper surface of the dust removal box via a bearing. A worm gear is fixedly sleeved on the outer surface of the rotating sleeve. The lower end of the rotating sleeve penetrates and extends into the interior of the dust removal box. An agitator rod arranged in a ring array is fixedly connected to the outer surface of the lower end of the rotating sleeve. A spray pipe arranged in a ring array is fixedly connected to the outer surface of the rotating sleeve.

[0008] The lower end of the spray pipe is equipped with a multi-stage dust removal device, and the multi-stage dust removal device includes an atomizing nozzle. The upper end of the atomizing nozzle is fixedly installed to the lower end of the spray pipe.

[0009] Preferably, the plurality of atomizing nozzles are arranged in a linear array at the lower end of the spray pipe, and an annular filter frame is fixedly sleeved on the outer surface of the rotating sleeve.

[0010] Preferably, the outer surface of the annular filter frame is mounted to the inner wall of the dust collector via a sealed bearing, a servo motor is fixedly mounted on the upper surface of the dust collector, and a worm gear is fixedly mounted on the output shaft of the servo motor via a coupling.

[0011] Preferably, the outer surface of the worm meshes with the tooth surface of the worm wheel, a water supply pipe is installed on the upper inner wall of the rotating sleeve through a sealed bearing, and a first solenoid valve is fixedly installed on the outer surface of the water supply pipe.

[0012] Preferably, a diversion pipe is fixedly connected to the outer surface of the water supply pipe, one end of the diversion pipe penetrates and extends into the interior of the dust removal box, and a second solenoid valve is fixedly installed on the outer surface of the diversion pipe.

[0013] Preferably, the outer surface of the diversion pipe is fixedly equipped with flushing nozzles arranged in a linear array, and the upper surface of the storage chamber body is provided with a breathing valve, the air outlet of the breathing valve being fixedly connected to a delivery pipe.

[0014] Preferably, one end of the conveying pipe is fixedly connected to the outer surface of the dust collector, a drain pipe is fixedly connected to the outer surface of the dust collector, a third solenoid valve is fixedly installed on the outer surface of the drain pipe, and a liquid level sensor is fixedly installed on the inner wall of the dust collector.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, a multi-stage dust removal device is used to first adsorb dust in the gas through water at the bottom of the dust removal box, and the adsorption efficiency is improved by the rotation of the stirring rod. Then, the atomized water sprayed by the atomizing nozzle adsorbs fine dust particles in the gas. Finally, the stainless steel filter in the annular filter frame further intercepts the dust, improving the quality of gas emissions.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: an environmentally friendly dust removal device for a ash storage silo top breathing valve, including a storage silo body 1, a dust removal box 2 fixedly connected to the upper surface of the storage silo body 1, an exhaust hole at the upper end of the dust removal box 2, a rotating sleeve 3 mounted on the upper surface of the dust removal box 2 via a bearing, a worm gear 4 fixedly sleeved on the outer surface of the rotating sleeve 3, the lower end of the rotating sleeve 3 penetrating and extending into the interior of the dust removal box 2, and a stirring rod 5 arranged in a ring array fixedly connected to the outer surface of the lower end of the rotating sleeve 3. The rotation of the stirring rod 5 serves to stir and break the air bubbles in the water, thereby enabling them to fully contact and adsorb the dust. A spray pipe 6 arranged in a ring array is fixedly connected to the outer surface of the rotating sleeve 3.

[0027] The lower end of the spray pipe 6 is equipped with a multi-stage dust removal device, which includes an atomizing nozzle 7. The upper end of the atomizing nozzle 7 is fixedly installed with the lower end of the spray pipe 6.

[0028] Multiple atomizing nozzles 7 are arranged in a linear array at the lower end of the spray pipe 6. An annular filter frame 71 is fixedly sleeved on the outer surface of the rotating sleeve 3. The spray pipe 6 sprays water through the atomizing nozzles 7, thereby adsorbing and removing dust particles in the air.

[0029] The outer surface of the annular filter frame 71 is installed to the inner wall of the dust collection box 2 via a sealed bearing. A servo motor 72 is fixedly installed on the upper surface of the dust collection box 2. The output shaft of the servo motor 72 is fixedly installed with a worm gear 73 via a coupling. A stainless steel filter screen is provided on the inner wall of the annular filter frame 71 for further interception of dust. The stainless steel filter screen is suitable for backwashing cleaning, which reduces the labor required for manual cleaning.

[0030] The outer surface of the worm 73 meshes with the tooth surface of the worm wheel 4. A water supply pipe 74 is installed on the inner wall of the upper end of the rotating sleeve 3 through a sealed bearing. A first solenoid valve 75 is fixedly installed on the outer surface of the water supply pipe 74. The water supply pipe 74 is connected to an external water pump to provide high-pressure water.

[0031] A diversion pipe 76 is fixedly connected to the outer surface of the water supply pipe 74. One end of the diversion pipe 76 passes through and extends into the interior of the dust collector 2. A second solenoid valve 77 is fixedly installed on the outer surface of the diversion pipe 76. The second solenoid valve 77 controls the connection of the diversion pipe 76.

[0032] A linear array of flushing nozzles 78 is fixedly installed on the outer surface of the diversion pipe 76. A breather valve 79 is provided on the upper surface of the storage chamber body 1. The outlet end of the breather valve 79 is fixedly connected to a conveying pipe 710. The conveying pipe 710 is inverted U-shaped to prevent backflow of the treated water. A flow sensor is provided on the conveying pipe 710. When gas flow is detected, the device is activated. The conveying pipe 710 can also be used to transport gas and dust by means of a fan.

[0033] One end of the conveying pipe 710 is fixedly connected to the outer surface of the dust collector 2. A drain pipe 711 is fixedly connected to the outer surface of the dust collector 2. A third solenoid valve 712 is fixedly installed on the outer surface of the drain pipe 711. A liquid level sensor 713 is fixedly installed on the inner wall of the dust collector 2. The liquid level sensor 713 is used to monitor the water level at the bottom of the dust collector 2. One end of the drain pipe 711 is connected to an external water treatment device.

[0034] The multi-stage dust removal device first uses water at the bottom of the dust collection box 2 to initially adsorb dust in the gas. During adsorption, the stirring rod 5 is rotated to improve the adsorption efficiency. Then, the atomized water sprayed by the atomizing nozzle 7 adsorbs fine dust particles in the gas. Finally, the stainless steel filter in the annular filter frame 71 further intercepts the dust, improving the quality of gas emissions. It also has the effect of automated flushing, cleaning and sewage discharge, reducing manual labor.

[0035] The working process of this utility model:

[0036] Step 1: When the internal pressure of the storage chamber 1 is high, the gas and sintering ash are transported through the breathing valve 79 to the water at the bottom of the dust collector 2 via the conveying pipe 710. Since the conveying pipe 710 is equipped with a flow sensor, when the gas is detected, the servo motor 72 is started. The servo motor 72 drives the meshing worm wheel 4 to rotate through the worm 73. The rotation of the worm wheel 4 drives the stirring rod 5 to rotate through the rotating sleeve 3. The rotation of the stirring rod 5 stirs the water at the bottom of the dust collector 2, thereby improving the adsorption efficiency of dust in the gas.

[0037] Step 2: Simultaneously open the first solenoid valve 75, and the water supply pipe 74 delivers cleaning water to the spray pipe 6 through the rotating sleeve 3. The water is then sprayed out through the atomizing nozzle 7, which adsorbs the fine dust particles in the gas. The dust particles that have adsorbed the water vapor fall into the water at the bottom of the dust collection box 2. Finally, any remaining dust particles are intercepted by the stainless steel filter in the annular filter frame 71, thus achieving multi-stage dust removal. The purified gas is discharged through the exhaust port at the top of the dust collection box 2.

[0038] Step 3: After dust removal is completed, close the first solenoid valve 75 and open the second solenoid valve 77. At this time, the water in the diversion pipe 76 washes the rotating annular filter screen frame 71 through the flushing nozzle 78. The dust adsorbed under the stainless steel filter screen is washed off and dropped to the bottom of the dust collection box 2 through backwashing. After rinsing is completed, close the second solenoid valve 77. When the liquid level sensor 713 senses that the liquid level at the bottom of the dust collection box 2 has reached the preset maximum value, open the third solenoid valve 712 to discharge the wastewater containing dust through the drain pipe 711, so that it can be transported to the subsequent treatment equipment for pollution-free treatment until the water inside the dust collection box 2 reaches the preset minimum value.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
