A purification tower for air pollution control

Abstract

The invention discloses a purification tower for air pollution control, comprising a purification tower body arranged on a purification tower base, a swirl filter assembly and several groups of water bath purification assemblies installed in the purification tower body, the swirl filter assembly includes Cyclone separator, centrifugal purification cylinder and filter bar, water bath purification components include trumpet-shaped liquid storage tank and shroud, multiple sets of corrugated corrugated plates, flexible slide between the shroud and the platform on the liquid storage tank Sleeve connection, the assembly method between the connecting rod and the sleeve of the flexible sliding sleeve is clearance fit; the design of the swirl filter assembly makes full use of the principle of swirl separation and centrifugal separation, and the self-excited vibration structure designed in the water bath purification assembly strengthens The mixing effect of air in the purification liquid is improved, so that the purification effect of the water bath purification component is better than that of the spray purification without power. The self-excited vibration structure design without power has much higher reliability than the spray system components, and the cost is low. , suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of separation of atmospheric harmful substances, in particular to a purification tower for air pollution control. Background technique [0002] Air pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, present in sufficient concentrations for sufficient time, and thus endanger the comfort, health and welfare of the human body or the environment. Air pollutants enter the atmosphere (input) from man-made sources or natural sources, participate in the circulation process of the atmosphere, and after a certain residence time, are removed from the atmosphere (output) through chemical reactions, biological activities and physical deposition in the atmosphere. If the output rate is less than the input rate, it will be relatively concentrated in the atmosphere, resulting in an increase in the concentration of a certain substance in the atmosphere. When the co...

Problems solved by technology

Filtration and adsorption is a conventional method, but the requirements for the filter plate, especially the filter element packing are relatively high. Because the air contains a certain amount of solid particles, it is easy to cause the blockage of the filter device of the purification tower, which affects the normal use of the purification tower. replace

For the common clogging problem in filtration adsorption, adding vibration to reduce the clogging rate and adding a roller brush to reduce the clogging rate are an improved solution, but no matter whether you choose to add vibration or roller brush, you need to match the corresponding drive system and control system. Additional Circuit control increases the complexity of the system, and it is well known that the more complex the system, the higher the failure rate

Spray purification technology is aimed at harmful gases in air pollution. The air and purification liquid are fully mixed through spraying to filter out the harmful gas soluble in water in air pollution, and the purification effect is more sufficient. However, the spray system High-pressure pumps and corresponding pipelines, nozzles, etc. are required for implementation. The nozzles are easy to block, the reliability of the sprinkler system is not high, and the use and maintenance costs are high in a long period of time.

The purification tower in the prior art looks very beautiful as a model project, but due to the extremely low cost performance, the promotion value is not high
