Description

Technical Field

[0001] The invention relates to the technical field of waste gas purification, and in particular to a volatile organic waste gas collection and purification device. Background Art

[0002] Waste gas purification mainly refers to the work of treating industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial sites. Common waste gas purifications include factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc. Waste gas emitted from industrial production often has harmful effects on the environment and human health. Purification measures should be taken before it is discharged into the atmosphere to make it meet the requirements of waste gas emission standards. This process is called waste gas purification.

[0003] In the process of collecting, purifying and reducing dust from volatile organic waste gas, it is necessary to pay attention to multiple aspects to ensure efficient, safe and environmentally friendly treatment effects. At the same time, this process can be used in conjunction with a variety of equipment to achieve the best waste gas treatment effect. For example, dust removal equipment: wet high-voltage electrostatic dust removal equipment, filter cartridge dust collector, etc., are used to remove dust and particulate matter from waste gas and protect subsequent treatment equipment from wear and blockage.

[0004] However, it is inconvenient to clean the filter cartridges in existing dust removal equipment. Usually, multiple vibration devices are installed on the outside of the filter equipment or the filter cartridges are manually disassembled and knocked for cleaning. However, the above cleaning methods are too inefficient and require a lot of manpower and material resources, which not only increases production costs, but also has a general cleaning effect. In addition, the filter cartridges cannot be cleaned in time in the filter equipment, and usually need to be shut down for cleaning, which also increases the risk of damage to the filter equipment. Therefore, a volatile organic waste gas collection and purification device is proposed to solve the above problems. Summary of the invention

[0011] Furthermore, a gas delivery pipe connected to the filter cartridge is installed on the filter device, a connecting pipe is fixedly connected between the filter device and the purification device, and a solenoid valve is installed on the connecting pipe for conveying the filtered gas.

[0012] Furthermore, two symmetrically arranged vertical plates are welded and installed on the upper surface of the filtering device, the connecting shaft is installed between the two vertical plates through a bearing, and a mounting platform welded to the outer wall of the left vertical plate is fixedly installed on the bottom end of the driving motor.

[0013] Furthermore, a scraper block is fixedly mounted on the inner side of the vibration plate and abuts against the outer surface of the filter cartridge, and the vibration plate has a circular ring shape.

[0014] Furthermore, a connecting ball groove and a through hole are provided inside the vibration plate, and a rotating connecting ball head rotatably connected to the connecting ball groove is fixedly installed at the bottom end of the connecting rod.

[0015] Furthermore, the guide rod passes through the interior of the vibration plate through a perforation, a connecting block fixed to the lower surface of the vibration plate is welded to the top of the spring, and the spring surrounds the outside of the guide rod.

[0016] Furthermore, a pump chamber and two oppositely arranged water supply channels are provided in the pump casing, the two water supply channels are both connected to the pump chamber, and connecting pipes respectively connected to the two water supply channels are installed on the outer walls on the opposite sides of the pump casing, and the two connecting pipes are respectively fixedly connected to the nozzle and the water tank at one end away from each other.

This synchronization improves the cleaning efficiency and reduces the decrease in filtration efficiency and increase in energy consumption caused by excessive dust accumulation. Through effective cleaning measures, the replacement frequency and maintenance cost of the filter cartridge can be reduced.

[0022] 2. The volatile organic waste gas collection and purification device, through the installation of the guide rod, realizes the limitation of the vibration plate, so that it can reciprocate linearly up and down, thereby being able to stably and fully squeeze the spring to cause it to deform. By continuously squeezing the spring, the pressure applied to the spring is changed. At this time, the spring will vibrate due to the periodic change of pressure, causing the vibration plate to shake off the impurities inside the filter cartridge.

[0023] 3. The volatile organic waste gas collection and purification device uses vibration cleaning with automatic cleaning function. It can complete the cleaning process in a short time and prepare for the next operation. This automatic cleaning method does not require human intervention, which greatly improves the cleaning efficiency. At the same time, the vibration cleaning filter cartridge can show significant benefits in automatic cleaning, easy maintenance and installation, and noise control. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 A volatile organic waste gas collection and purification device includes a purification device 1 for waste gas collection and purification and a filter device 2 and a filter cartridge 4 arranged inside the filter device 2 for gas filtering. The filter device 2 is provided with a gas transmission pipe connected to the filter cartridge 4. A connecting pipe 3 is fixedly connected between the filter device 2 and the purification device 1. The connecting pipe 3 is provided with a solenoid valve for conveying the filtered gas. The purification device 1 and the filter device 2 are both conventional devices known to the public in the prior art, so their specific structural composition and working principle will not be described in detail in this article.

[0035] In this embodiment, in order to improve the filtering efficiency of the filter cartridge 4, a cleaning mechanism for cleaning the filter cartridge 4 is provided on the filter device 2; the cleaning mechanism includes a rotating disk 5 arranged above the filter device 2, a vibration plate 7 sleeved on the outer surface of the filter cartridge 4, a connecting rod 6 hingedly installed on the outside of the rotating disk 5 and extending into the filter device 2 and rotatably connected to the vibration plate 7, a vibration structure 9 fixedly installed on the inner bottom wall of the filter device 2 and connected to the lower surface of the vibration plate 7, and a sprinkler structure 11 installed above the filter device 2 and on the outer surface of the vibration plate 7; the vibration structure 9 includes a guide rod 901 and a spring 902 fixedly installed on the inner bottom wall of the filter device 2.

[0036] Specifically, the watering structure 11 includes a pump housing 1101 fixedly mounted on the upper surface of the filter device 2, two rotating gears 1103 rotatably disposed inside the pump housing 1101 and meshing with each other, a nozzle 1105 fixedly mounted on the outer surface of the vibration plate 7, and a plurality of nozzles 1106 fixedly connected to the nozzle 1105 on one side close to the vibration plate 7 and arranged at equal distances;

[0037] In order to increase the linkage between the structures, in this embodiment, a transmission mechanism 8 for linkage between the rotating disk 5 and the water sprinkling structure 11 is installed on the upper surface of the filter device 2. The transmission mechanism 8 includes a driving motor 801 and a connecting shaft 804 arranged above the filter device 2. One end of the connecting shaft 804 is fixed to the outside of the rotating disk 5, and the connecting shaft 804 passes through the inside of the pump housing 1101 and is fixed to one of the rotating gears 1103. A transmission gear 802 is fixedly installed on the output shaft of the driving motor 801, and a driven gear 803 meshing with the transmission gear 802 is fixedly installed on the outside of the connecting shaft 804. Through the installation of the transmission mechanism 8, the rotating disk 5 and the water sprinkling structure 11 are used in linkage, so that the synchronous operation of gas filtration, reciprocating cleaning and water sprinkling can ensure that the surface of the filter cartridge 4 is always kept clean while the filter device 2 continues to work. This synchronization improves the dust cleaning efficiency and reduces the decrease in filtration efficiency and increase in energy consumption caused by excessive dust accumulation.

[0038] Specifically, two symmetrically arranged vertical plates 10 are welded and installed on the upper surface of the filter device 2, the connecting shaft 804 is installed between the two vertical plates 10 through a bearing, and the bottom end of the driving motor 801 is fixedly installed with a mounting table welded to the outer wall of the left vertical plate 10. The number of rotating disks 5, connecting rods 6 and vibration structures 9 are two, and the two rotating disks 5 are symmetrically arranged on the side away from the two vertical plates 10, and the nozzle 1105 is installed on the outer surface of the vibration plate 7 through a clamp and bolts. A sewage discharge cover is detachably installed at the bottom end of the filter device 2.

[0039] In this embodiment, a scraper block 71 is fixedly installed on the inner side of the vibration plate 7 and abuts against the outer surface of the filter cartridge 4. The outer shape of the vibration plate 7 is annular. A connecting ball groove 73 and a through hole 74 are provided inside the vibration plate 7. A rotating connecting ball head 61 is fixedly installed at the bottom end of the connecting rod 6 and is rotatably connected to the connecting ball groove 73. A reserved groove is provided in the scraper block 71 for installing a cleaning brush, so that the reciprocating motion of the vibration plate 7 can perform a variety of cleaning methods.

[0040] The guide rod 901 passes through the inside of the vibration plate 7 through the through hole 74, the top of the spring 902 is welded with a connecting block 903 fixed to the lower surface of the vibration plate 7, and the spring 902 surrounds the outside of the guide rod 901. When the vibration plate 7 reciprocates up and down, the guide rod 901 limits and continuously squeezes the spring 902, and the deformation vibration of the spring 902 cooperates with the scraper block 71 to clean up the impurities in the filter cartridge 4.

[0041] It is understandable that, by installing the guide rod 901, the vibration plate 7 is limited so that it can reciprocate linearly up and down, thereby being able to stably and fully squeeze the spring 902 to deform it. By continuously squeezing the spring 902, the pressure applied to the spring 902 is changed. At this time, the spring 902 will vibrate due to the periodic change of pressure, so that the vibration plate 7 shakes off the impurities inside the filter cartridge 4. The vibration cleaning has an automatic cleaning function, which can complete the cleaning process in a short time and prepare for the next operation. This automatic cleaning method does not require manual intervention, which greatly improves the cleaning efficiency. At the same time, the vibration cleaning method can show significant benefits in automatic cleaning, easy maintenance and installation, and noise control.

[0042] In this embodiment, a pump chamber 1102 and two oppositely arranged water delivery channels 1104 are provided in the pump housing 1101. The two water delivery channels 1104 are both connected to the pump chamber 1102, and connecting pipes 1107 respectively connected to the two water delivery channels 1104 are installed on the outer wall on the opposite side of the pump housing 1101. The two connecting pipes 1107 are fixedly connected to the nozzle 1105 and the water tank at the separated ends.

[0043] It should be noted that the two rotating gears 1103 are arranged up and down and matched with the pump chamber 1102, and the two rotating gears 1103 are rotatably installed in the pump chamber 1102, and the connecting pipe 1107 connected to the nozzle 1105 is a hose. The inside of the vibration plate 7 and the scraper block 71 are both provided with a connected through hole 72, and the nozzle 1106 uses the through hole 72 to clean the filter cartridge 4.

[0044] The working principle of the above embodiment is:

[0045] When in use, the motor 801 is driven and the transmission gear 802 is engaged with the driven gear 803 to drive the connecting shaft 804. The rotation of the connecting shaft 804 drives the rotating disk 5 and one of the rotating gears 1103 to rotate. The rotating disk 5 rotates through the connecting rod 6 to drive the vibration plate 7 to reciprocate up and down. When the vibration plate 7 reciprocates up and down, it is limited by the guide rod 901 and continuously squeezes the spring 902. The deformation vibration of the spring 902 cooperates with the scraper block 71 to clean up the impurities in the filter cartridge 4. At the same time, the rotating gear 1103 used for transmission is engaged with another rotating gear 1103, and the gear pump principle is used to pump water and transport it to the nozzle 1105, and finally spray it out through the nozzle 1106, so that the synchronous operation of gas filtration, reciprocating cleaning and water sprinkling can ensure that the surface of the filter cartridge 4 is always kept clean while the filter device 2 continues to work. This synchronization improves the cleaning efficiency and reduces the decrease in filtration efficiency and increase in energy consumption caused by excessive dust accumulation.

[0046] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and they can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
