Wet static dedusting device

Abstract

The invention discloses a wet static dedusting device which comprises a tower body, an electrode support and an insulated pillar, wherein the electrode support is installed in the tower body. The wet static dedusting device is characterized in that a plurality of suspended electrode rods are fixedly arranged on the electrode support; a hollow condenser tube is sleeved outside the electrode rods; a clapboard is sealed and fixedly arranged in the tower body; the condenser tube is fixedly arranged on the clapboard, with the lower end running out of the clapboard; a water inlet is arranged on the tower body; one end of the insulated pillar is fixedly connected with the electrode support, and the other end of the insulated pillar is fixedly connected with the tower body; a waste gas inlet and a dirt drain port are arranged at the lower end of the tower body; and a gas exhaust port is arranged at the upper end of the tower body. The wet static dedusting device has the advantages that a uniform water film renewed constantly is formed on the inner wall of the condenser tube and serves as a dust collecting electrode when the electrode rods discharge so that a uniform electrostatic field can be formed in the condenser tube; charges of the high voltage electrostatic electrons generated by the electrode rods adhere to the harmful particles in the exhaust gas, and under the action of the high voltage electric field, the harmful particles directionaly migrate to the wall of the condenser tube and then flow down with the water film to be drained; the ozone or plasma free radicals generated when the electrode rods discharge can oxidize and remove the fetid substances in the exhaust gas, so the exhaust gas can get deep purification treatment; and the wet static dedusting device has good dedusting and purifying effects and the whole equipment can operate safely for a long period.

Description

technical field [0001] The invention relates to a dust removal device for industrial waste gas, in particular to a wet electrostatic dust removal device suitable for purifying high temperature, oily and wet waste gas discharged by industry. Background technique [0002] With the development of industry, industrial tail gas, waste gas, etc. have caused serious pollution to the environment, especially the high-temperature oily and wet waste gas discharged from industry (such as high-temperature oily and wet smoke discharged from printing and dyeing setting machines, etc.), which seriously endangers human habitation. living environment and human health. At present, many large and medium-sized industrial enterprises use spraying devices to purify exhaust gas, but this can only precipitate harmful substances with particles above 1 micron, while for dust removal and purification of high-temperature exhaust gas with particles below 1 micron containing harmful substances such as smo...

AI Technical Summary

Problems solved by technology

At present, many large and medium-sized industrial enterprises use spraying devices to purify exhaust gas, but this can only precipitate harmful substances with particles above 1 micron, while for dust removal and purification of high-temperature exhaust gas with particles below 1 micron containing harmful substances such as smoke, oil fume, etc. The effect is not ideal

[0003] In order to purify the high-temperature, oily, and humid flue gas with particles below 1 micron, wet electrostatic precipitators are also used. It mainly uses the electrostatic field to make harmful substance particles below 1 micron attached and charged by electrons, and is captured by static electricity. On the pipe wall of the field, and then flow down along the water film on the pipe wall, so as to achieve the purpose of dust removal, but the current wet electrostatic precipitator basically uses nozzle spraying to provide the water film, which is easy to cause a short circuit in the electrostatic field and cause The entire wet electrostatic precipitator fails, affecting the dust removal effect
