Dust removal method of wet dust collector


The wet duster dust removal method uses water or other liquids to collide with the dust particles in the dust-containing airflow. When the dust particles meet the spray liquid film, droplets, bubbles or wet walls, wetting, condensation, diffusion and precipitation occur And other processes. The agglomeration diameter of dust particles and droplets increases, the dust particles are easily separated from the gas, and the dust-containing gas is purified. Due to the variety of dust removal mechanisms and high dust removal efficiency, wet dust removal methods with a diameter of less than 0.1 μm still have high dust removal efficiency. The wet dust removal method has high purification efficiency, ensuring high temperature, high humidity, flammable and explosive dust-containing gas . Wet dust removal can remove toxic and harmful gases in exhaust gas through liquid absorption while removing dust particles, but dry dust removal cannot. However, the wet type dust collector has a large amount of water, and the slurry formed by the combination of liquid and dust should be strictly treated to prevent secondary pollution and cause heat dissipation in the high-temperature dust-containing airflow. Wet dust collectors have low dust removal efficiency for hydrophobic or hydraulic dust. Protect against freezing in winter in cold northern areas.

As early as 1892, g.zsc.hohe obtained a patent for designing a very primitive wet-grid dust collector, which became an effective dust removal device at that time. With the rapid development of industry and the continuous improvement of people's requirements for environmental protection, various wet dust collectors have been developed. So far, the commonly used wet dust collectors mainly include spray scrubbers, water film dust collectors, self-excited dust collectors, foam dust collectors and Venturi dust collectors. Venturi dust collectors are simple and compact in structure and occupy a small area. , Stable operation, relatively low price and other advantages, has become a widely used wet dust collector.


Due to the shortcomings of large water consumption and prone to secondary pollution, wet dust collectors have severely restricted the development of traditional wet dust collectors. In recent years, domestic researchers have combined wet dust removal methods with other dust removal methods, and developed cyclones, Wenqiu The electrostatic precipitator and other dedusting equipment have improved the dedusting efficiency and reduced the water pollution in the dedusting process. High-temperature dust removal technology for liquid metal cleaning is being studied abroad. In Fuzhou, Canada and other continents, cross-flow rotating packed beds have been developed using a combination of centrifugal sedimentation, mechanical rotary collision, and droplet capture mechanisms. Experiments show that the classification efficiency of cross-flow rotating packed beds varies with speed, liquid-gas ratio and The increase of air volume increases. The dust removal efficiency of 5 is 96%, and the classification dust removal efficiency is greater than that of traditional wet dust collectors, which can be used to remove micron fine particles. Yuan Yuan also improved the problems of pulse dust collectors and developed a wet dust collector with small maintenance and simple structure. 5%。 Wet dust collector will change the traditional s-shaped channel to a double w-shaped channel, increasing the probability of dust-laden airflow impacting water surface and water contact, the dust removal efficiency can reach 99.5%. Jin Ding and others used wesp to treat smoke pollution, and sprayed water mist on the discharge electrode and corona area. Wesp is easy to excite electrons, realize low-voltage corona discharge, improve dust removal efficiency, and do not generate secondary dust.


Dust removal method of wet dust collector :

 

A spray system is provided in the box of the wet type dust collector. The circulating water is sprayed out through the spray pipe and the nozzle to form a misty space. When the dusty air passes through, the misty droplets will intercept the solid powder particles and collide Condensation occurs. When there are more solid impurities in the liquid and the condensed particles are larger, they will fall to the bottom of the dust collector and be discharged.
