Abstract

The invention relates to an industrial fire coal boiler smoke desulphurization dedusting device adopting drug spraying desulphurization, liquid adsorption, cyclone Venturi dedusting, water bath gas-liquid separation, clear water purification and automatic deslag. The device which is a round or a quadrate cylindrical sealed body is characterized in that: an upper separation plate and a lower separation plate divide the internal of the device into a desulphurization chamber and a dedusting chamber, the top of the device is provided with a smoke outlet, the bottom of the device is communicated with a sediment pool, and a slag scraping machine is arranged in the sediment pool; and the device is provided with liquid switches, solenoid valves, an alkaline liquid pool, the sediment pool and a filter pool. An alkaline liquid can be automatically added, and clear water and the alkaline liquid can be cyclically used, so dual cycle of dust water and the alkaline liquid is realized, and discharge standards are reached.

Description

technical field [0001] The invention relates to an industrial coal-fired boiler flue gas purification device, in particular to an industrial coal-fired boiler flue gas desulfurization and dust removal device using liquid as a separation adsorbent. Background technique [0002] Sulfur dioxide, nitrogen oxides and dust in the waste gas produced by coal-fired / heavy oil boilers have caused serious pollution to the environment. Nitrogen oxides are major pollutants that are difficult to control. Many small and medium-sized enterprises launched in the 1990s in our country, such as textile printing and dyeing enterprises, used a large number of oil-fired boilers in production. The soot, sulfur dioxide and nitrogen oxides produced by the oil-fired boiler during the production process have caused environmental pollution to the surrounding areas. According to environmental protection requirements, the polluted equipment, especially the flue gas produced by the oil-fired boiler, must b...
