Description

TECHNICAL FIELD

[0001] The utility model belongs to industrial dust removal technical field, concretely relates to an industrial dust removal system of air filter exemption. BACKGROUND

[0002] In the industrial production process, the dust and harmful gas generated pose a serious threat to the environment and human health. In order to reduce the emission of these pollutants, industrial dust removal systems are widely used. Traditional industrial dust removal systems usually rely on air filters, such as filter bags or filter cartridges, to capture and filter dust. However, this traditional method has a series of defects and limitations.

[0003] All industrial dust collectors on the market must pass through a series of filter bags, filter cartridges or water to complete the final dust filtration and discharge. Due to the increasingly stringent emission standards, the higher the mesh size of the filter or the water filtration, the greater the gas flow resistance, the poorer the dust collection effect, the greater the power demand of the fan, the more energy consumption, the larger the equipment construction and investment cost, and the formation of a large amount of waste water and sludge secondary pollution, vicious cycle, limited efficiency improvement but increased enterprise equipment, power and waste disposal cost. Because the dust particles collected by this filter bag filter cartridge are very fine, it is easy to cause secondary air pollution when collecting dust, and it is also difficult to clean and maintain.

[0004] In order to overcome the defects of traditional industrial dust removal systems, an industrial dust removal system without air filter is proposed. By canceling the traditional air filter, the system resistance is reduced, thereby reducing the energy consumption of the fan. The replacement of filter bags or filter cartridges is eliminated, greatly reducing the maintenance cost and downtime. The use of spray dust collection liquid and photochemical reaction mixing effectively reduces the possibility of secondary dust raising. The industrial dust removal system without air filter can improve the dust removal efficiency, reduce the operation and maintenance cost, and reduce the impact on the environment, providing a more efficient, economical and environmentally friendly solution for industrial dust removal.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The drawings will be described below in conjunction with the Figures 1-5 The present application will be further described in detail,

[0027] The embodiments of the present application disclose an air filter-free industrial dust removal system, which comprises an initial reaction chamber 1, a dust capture separation mechanism 4 and a condensing purifier 5. The initial reaction chamber 1 is connected with a gas inlet pipe 2 of industrial dust gas, and the bottom of the initial reaction chamber 1 is communicated with a dust collection box 3. The dust capture separation mechanism 4 is continuously provided with at least two groups from bottom to top. The multiple groups of dust capture separation mechanisms 4 can gradually increase the capture of dust particles and promote the rapid growth of the dust particles, thereby improving the purification efficiency and ensuring the emission quality. The dust capture separation mechanism 4 comprises a variable diameter pipeline 41, a spray head arranged in the variable diameter pipeline 41 and spraying industrial dust gas, and a photochemical reaction mixing chamber 43 arranged above the variable diameter pipeline 41. The air inlet of the condensing purifier 5 is communicated above the dust capture separation mechanism 4, and the air outlet is communicated with a fan 6.

[0028] The fan 6 inhales the industrial dust gas through the continuous variable diameter pipeline 41, sprays specific dust collection liquid at specific points in a quantitative and continuous manner, and then enters the photochemical reaction mixing chamber 43. The above process is continuously repeated multiple times to increase the capture of dust particles and promote the rapid growth of the dust particles, so as to facilitate the rapid separation of dust and air, purify the air, and generate no waste liquid and sludge. The air is further purified in the condensing purifier 5 and then discharged. Due to the increase in dust size, dust collection is easy, dust raising is not easy, and secondary air pollution is avoided.

[0029] The variable diameter pipeline 41 includes a lower section pipe 4101, a middle section pipe 4102 and an upper section pipe 4103 flange butted from bottom to top, and a spray head arranged in the middle section pipe 4102. The spray head is connected with the spray pipe 42 on the middle section pipe 4102. The flange butt design of the lower section pipe 4101, the middle section pipe 4102 and the upper section pipe 4103 facilitates installation and maintenance, can quickly replace damaged parts, reduces downtime, improves equipment reliability and operating efficiency. The spray head is directly connected with the spray pipe 42, which can more accurately control the flow and distribution of the spray liquid, improve the dust collection efficiency, and reduce energy consumption and spray liquid waste.

[0030] The photochemical reaction mixing chamber 43 includes a mounting bracket 4301, a plurality of ultraviolet lamps 4302 arranged at equal intervals in a ring shape and mounted on the mounting bracket 4301, an outer shell 4303 sleeved on the outer side surface of the mounting bracket 4301, and a connecting cover 4304 flange butted on the top of the outer shell 4303. Through the reasonable layout of the mounting bracket 4301, the ultraviolet lamp 4302 and other components, the structure of the mixing chamber is compact and the maintenance is simple. The equal interval arrangement of the ultraviolet lamp 4302 ensures the uniformity and efficiency of the photochemical reaction. The mounting bracket 4301 includes an upper flange plate 4306, an upper annular groove 4307 fixed on the bottom of the upper flange plate 4306, a lower flange plate 4308, a lower annular groove 4309 fixed on the top of the lower flange plate 4308, a plurality of connecting rods 4310 connected between the lower annular groove 4309 and the upper annular groove 4307 and arranged at equal intervals in a ring shape, and a mounting hole 4311 formed in the upper annular groove 4307 and matched with the mounting and fixing of the ultraviolet lamp 4302. The design of the upper flange plate 4306, the lower flange plate 4308 and the connecting rod 4310 makes the whole mounting bracket 4301 stable in structure, ensuring the safety and stability of the ultraviolet lamp 4302 and other components. The design of the mounting hole 4311 facilitates the installation and replacement of the ultraviolet lamp 4302, reducing the maintenance difficulty.

[0031] The outer shell 4303 includes a left half shell 4312 and a right half shell 4313, the butt joint surface of the left half shell 4312 and the right half shell 4313 is provided with a flange 4305, the left half shell 4312 and the right half shell 4313 are butted together through the bolts penetrating through the flange 4305 and are sleeved on the outer side surface of the upper annular groove 4307 and the lower annular groove 4309, and the left half shell 4312 and the right half shell 4313 are respectively flange butted with the upper flange plate 4306 and the lower flange plate 4308. The design of the left half shell 4312 and the right half shell 4313 facilitates assembly and disassembly, reducing the complexity of repair and replacement. The design of the flange 4305 and the bolt connection ensures the sealing of the outer shell 4303, prevents gas leakage and ensures the efficient operation of the system.

[0032] The industrial dust removal system of the air-free filter can effectively capture and separate dust particles through the design of multiple sets of dust capture and separation mechanisms 4, thereby improving the overall dust removal efficiency. The system resistance is reduced due to the elimination of traditional air filters, allowing the fan 6 to provide sufficient dust removal power with lower energy consumption, thereby saving energy. The need for replacement of filter bags or cartridges is eliminated, reducing the frequency and cost of maintenance and replacement of filter elements. By spraying dust collection liquid and mixing with photochemical reaction, not only can dust be effectively captured, but also secondary dust can be reduced when filter bags or cartridges are not properly cleaned. The system has a simple structure, easy to install, operate and maintain. Since there is no need to replace filter bags or cartridges, the safety risk faced by operators is reduced. The system can adapt to different types of industrial dust, especially for handling dust with high humidity and strong adhesion. The system processes dust through the photochemical reaction mixing chamber 43, avoiding the generation of a large amount of waste liquid and sludge, which is beneficial to environmental protection. The design of multiple sets of dust capture and separation mechanisms 4 increases the redundancy of the system, so that even if some components fail, the entire system can still operate normally. If the dust removal efficiency needs to be improved or the gas flow needs to be handled, the system can achieve this by adding more dust capture and separation mechanisms 4 or adjusting the size of the existing components.

[0033] Finally, it should be noted that the above-described only preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
