Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of waste gas purification devices, and in particular relates to a waste gas purification device for the treatment of waste salt fly ash. Background Technology
[0002] During the treatment of waste salt fly ash, complex chemical and physical reactions are involved, generating a large amount of waste gas containing various pollutants. This waste salt fly ash often originates from waste incineration power plants (especially when incinerating waste containing complex components such as chlorine), industrial hazardous waste incineration facilities, and high-temperature treatment stages of waste salt in some chemical production processes. Since waste salt fly ash itself contains heavy metals (such as lead, cadmium, mercury, etc.), acidic gases (such as hydrogen chloride, sulfur dioxide, etc.), and some organic pollutants (possibly from incompletely burned organic matter, etc.), if these waste gases are directly emitted into the atmosphere without effective treatment, heavy metals will enter the soil and water bodies through processes such as sedimentation, causing heavy metal pollution in the ecosystem, affecting the growth of animals and plants and human health. Therefore, it is necessary to filter and purify the waste gas generated during the treatment of waste salt fly ash.
[0003] However, traditional waste gas treatment technologies have many shortcomings when dealing with waste gas from waste salt fly ash treatment. For example, although simple physical filtration methods can remove some particulate matter, the filtered particles and impurities are very easy to adhere to the filter screen surface, which will cause clogging after long-term use, thereby reducing the filter screen's permeability, reducing waste gas filtration efficiency and clogging. At the same time, particles adhering to the filter screen surface for a long time will increase frictional loss when waste gas impacts the filter screen, thereby reducing the filter screen's life and increasing maintenance costs. Therefore, a waste gas purification device for the waste salt fly ash treatment process is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a waste gas purification device for the treatment of waste salt fly ash. By setting up a purification mechanism, specifically, when the rotating shaft rotates, the top turntable drives the impact block to rotate, causing the bottom impact block to be pushed downwards by the contact force. During the downward movement of the support sleeve, the spring is compressed and stores energy. Subsequently, the spring's rebound force drives the support sleeve to reset, forming a reciprocating motion. This vibration is transmitted through filter screen one and filter screen two, causing attached particles to detach and maintaining the permeability of the filter screens. This solves many shortcomings of traditional waste gas treatment technologies when dealing with waste salt fly ash waste gas. For example, although simple physical filtration methods can remove some particulate matter, the filtered particles and impurities easily adhere to the filter screen surface, causing blockage after prolonged use, thus reducing the filter screen's permeability, reducing waste gas filtration efficiency, and increasing blockage. Simultaneously, particles adhering to the filter screen surface for a long time increase frictional loss when waste gas impacts the filter screen, thereby reducing filter screen life and increasing maintenance costs.

The filter assembly 22 achieves a vibration effect through the adsorption mechanism 21, reducing the clogging of the filter screen by particles in the exhaust gas. When the rotating shaft 217 rotates, the top turntable 228 drives the impact block 229 to rotate, causing the bottom impact block 229 to be pushed downwards by the contact force.

There are two limit rings 225; the outer ring of the top limit ring 225 is welded to the inner wall of the support sleeve 223, and the inner ring of the top limit ring 225 is welded to the outer surface of the support rod 227.

The water supply assembly 31 includes a water pump 311. An inlet pipe 312 is connected to the inlet end of the water pump 311, and a water supply pipe 313 is connected to the outlet end of the water pump 311. Two atomizing pipes 314 are connected to the outlet end of the water supply pipe 313 on the side furthest from the water pump 311. The two atomizing pipes 314 respectively... The system is positioned above filter screens 221 and 222. A water supply pipe 313 extends through and into the purification chamber 111. The recovery assembly 32 includes a water storage tank 321. A return pipe 323 is connected to the inlet of the water storage tank 321.

The outlet of the water storage tank 321 is connected to the end of the inlet pipe 312 away from the water pump 311.
[0037] A specific application of this embodiment is as follows: In use, the air inlet pipe 113 is first connected to the waste salt fly ash treatment device. During the subsequent waste salt fly ash treatment process, the motor 212 is started to drive the gear 213 to rotate. At the same time, the support frame 211 provides a certain support force to the motor 212 through its fixed connection with the purification chamber 111. During the rotation of the gear 213, it will drive the gear ring 214 to move together. At the same time, during the rotation of the gear ring 214, its outer ring edge will rotate inside the purification chamber 111. During the rotation of the gear ring 214, it will drive the fixed bracket 215 to drive the rotating shaft 217 to rotate. During the rotation of shaft 217, the impeller 216 will rotate. At this time, the high-speed rotation of the impeller 216 creates a negative pressure inside the purification chamber 111. The airflow generated by the rotation of the impeller 216 draws the exhaust gas into the purification chamber 111 through the intake pipe 113. When the exhaust gas enters the purification chamber 111 through the intake pipe 113, it first contacts the baffle block 224. The baffle block 224 effectively reduces the airflow velocity, reducing the direct impact of the airflow on the filter screen 221. After the airflow enters the purification chamber 111, the rotation of shaft 217 will drive several impact blocks 229 to rotate via the top turntable 228. During the rotation of the top impact blocks 229, they will contact the bottom impact blocks 229. At this time, the bottom impact blocks 229, under the force, will cause the support sleeve 223 to move downwards. During the downward movement of the support sleeve 223, the top limiting ring 225 will also move. The top limiting ring 225 will then compress the spring 226. The spring 226, limited by the bottom limiting ring 225, will contract and store force. Simultaneously, the spring 226 will generate a certain rebound force, causing the support sleeve 223 to return to its original position. Meanwhile, the support sleeve 223 is held in place by the impact blocks 229. The continuous rotational contact causes the filter screens 221 and 222 to reciprocate up and down, thereby achieving the effect of continuous vibration of the support sleeve 223, which drives the filter screens 221 and 222. This reduces the possibility of clogging of the filter screens 221 and 222 while filtering the exhaust gas. The vibration of the filter screens 221 and 222 can dislodge the attached particles and maintain their permeability, thus continuously and efficiently filtering impurities in the exhaust gas and ensuring the purification effect. At the same time, the vibration can shorten the residence time of particles on the filter screens 221 and 222, reduce the friction and impact of particles on the filter screens, thereby extending the service life of the filter screens and reducing equipment maintenance costs.
[0038] Simultaneously, while filter screens 221 and 222 are filtering the exhaust gas, water pump 311 is activated to draw water from the water storage tank 321 through the inlet pipe 312, then transports it through the delivery pipe 313, and finally sprays it out through two atomizing pipes 314. The sprayed water effectively removes dust from the exhaust gas. Simultaneously, the sprayed water flows downwards along the inner wall of the purification chamber 111, and finally flows back into the water storage tank 321 through the return pipe 323. The water also flows through the return pipe 323... The wastewater is filtered through filter 322, which is a reverse osmosis (RO) filter used for desalination and removal of dissolved pollutants. It is suitable for treating high-salinity wastewater. After filtration, the water flows into the storage tank 321 and is then transported and sprayed for dust removal. This can significantly reduce the demand for fresh water and lower water treatment costs, which is especially important in areas with water shortages. Finally, the exhaust gas is filtered through filter screen 221 and sprayed with atomizing pipe 314 for dust removal. Fresh air is then discharged from exhaust pipe 112.
