Description

Liquid film filtering type flue gas cleaner

Technical field

The utility model relates to a kind of smoke eliminator, particularly a kind of liquid film filtering type flue gas cleaner.

Background technology

The harm that flue dust that boiler, kiln are discharged and waste gas cause is well-known, people design various flue gas purifying equipments for this reason, to remove flue dust and other harmful components in boiler, the kiln discharging flue gas, yet owing to various boilers, kiln burnt fuel difference, combustion system difference, flue dust that is produced and waste gas also are not quite similar on physical form and chemical composition, and this just makes existing various flue gas purifying equipment: screw type deduster is invalid to the lighter flue dust of proportion; The deduster filtrate of filtering type easily stops up, and needs periodic cleaning or changes filtrate; The deduster of fountain is as the special-purpose desulfurizing dust-collector of the disclosed coal-burning boiler of Chinese patent CN2377452Y, though the energy dedusting can be sloughed the SO in the flue gas again ₂, SO ₃Deng pernicious gas, but the alkaline solution cleannes of using are had relatively high expectations, shower nozzle stops up easily.

Summary of the invention

Technical problem to be solved in the utility model is the deficiency that overcomes above-mentioned existing boiler, kiln gas cleaning equipment, and a kind of pernicious gas composition and the also not susceptible to plugging liquid film filtering type flue gas cleaner that can dedusting can slough in the flue gas is provided.

The technical scheme in the invention for solving the technical problem is: this pernicious gas composition and the also not susceptible to plugging liquid film filtering type flue gas cleaner that can dedusting can slough again in the flue gas, it comprises vertical cylindrical shell, the air inlet pipe that outlet flue is provided with downwards in the vertical cylindrical shell, the flue gas filter screen dewater unit that flue gas liquid film filter that the air inlet pipe top is provided with in the vertical cylindrical shell and flue gas liquid film filter top are provided with, purified gas outlet is offered at the top of vertical cylindrical shell, the lower end of vertical cylindrical shell is taper, dust-exhausting port is set, dust-exhausting port is equipped with locking device, and described flue gas liquid film filter is by last annular header, second line of a couplet ring and be arranged on annular header and the umbrella frame shape solution dispenser that the tilting sparge pipe of second line of a couplet interannular constitutes and the filter screen that adheres to above thereof constitute, the purified solution import of going up on the annular header is drawn by woven hose, the upper end of going up the tilting sparge pipe of annular header and second line of a couplet interannular is communicated with last annular header, goes up annular header, upward offer fluid hole on the sidewall that annular header and the tilting sparge pipe of second line of a couplet interannular make progress; Described flue gas filter screen dewater unit is by first line of a couplet ring, second line of a couplet ring and be arranged on umbrella frame shape support and its filter screen that adheres to above that the tilting connecting rod of second line of a couplet interannular constitutes and constitute.Such flue gas purifying equipment, be installed in boiler, the outlet flue of kiln, at boiler, the composition of the contained pernicious gas of kiln discharging flue gas, use purified solution of different nature, during work, purified solution flows in the tilting sparge pipe of annular header and the setting of second line of a couplet interannular by the last annular header of umbrella frame shape solution dispenser, the fluid hole of being offered on upper side wall by last annular header and tilting sparge pipe sprays to the filter screen that adheres to above the umbrella frame shape solution dispenser then, because the infiltration and the tension force effect of purified solution, spray to continuously on the filter screen that the purified solution of filter screen adheres on umbrella frame shape solution dispenser and form one deck liquid film, when the tension force that the dust-laden in entering vertical cylindrical shell and the flue gas of other pernicious gas overcome purified solution passes through, flue dust in the flue gas will be by the capture of blocking of this liquid film type filter screen, meanwhile, pernicious gas composition in the flue gas also fully carries out neutralization reaction with purified solution, and along with the continuous ejection of purified solution, will be deposited along with the bottom that purified solution be wandered vertical cylindrical shell by block material that the flue dust that captures and the pernicious gas composition in the flue gas and purified solution reaction generate of liquid film type filter screen, after the material of pernicious gas composition and purified solution reaction generation in flue dust that deposits in the vertical cylindrical shell and the flue gas reaches some, the locking device of vertical cylindrical shell lower end dust-exhausting port configuration is opened, the material that pernicious gas composition and purified solution reaction generate in the flue dust of discharge deposition and the flue gas; Such flue gas purifying equipment, flue gas by the umbrella frame shape solution dispenser and the flue gas liquid film filter of its filter screen that adheres to above formation continues upwards, when the flue gas filter screen dewater unit that constitutes by umbrella frame shape support and the filter screen that adheres to above it, flue gas institute carrying liqs will be stopped and accumulate on this filter screen by the filter screen of umbrella frame shape bracket supports, and accumulating in the bottom that liquid on this filter screen is wandered vertical cylindrical shell the most at last, flue gas after being purified can reach the requirement of dehydration discharging like this.

The flue gas liquid film filter that the air inlet pipe top is provided with in the above-mentioned liquid film filtering type flue gas cleaner, vertical cylindrical shell can be the single-stage flue gas liquid film filter that is made of a umbrella frame shape solution dispenser and its filter screen that adheres to above; It also can be the stacked multistage flue gas liquid film filter of forming of single-stage flue gas liquid film filter that constitutes by umbrella frame shape solution dispenser and its filter screen that adheres to above more than.

Above-mentioned liquid film filtering type flue gas cleaner, the flue gas filter screen dewater unit that flue gas liquid film filter top is provided with can be the single-stage flue gas filter screen dewater unit that is made of a umbrella frame shape support and its filter screen that adheres to above; It also can be the stacked multistage flue gas filter screen dewater unit of forming of single-stage flue gas filter screen dewater unit that constitutes by umbrella frame shape support and its filter screen that adheres to above more than.

The umbrella frame shape support of the flue gas filter screen dewater unit that the umbrella frame shape solution dispenser of the flue gas liquid film filter that the air inlet pipe top is provided with in the above-mentioned liquid film filtering type flue gas cleaner, vertical cylindrical shell and flue gas liquid film filter top are provided with can be positive umbrella; Also can be down umbrella.

This liquid film filtering type flue gas cleaner provided by the utility model, simple in structure, dedusting and waste gas purifying efficiency height, and be difficult for stopping up, and at the composition of the contained pernicious gas of boiler, kiln discharging flue gas, can use purified solution of different nature, thereby suit to install and use in the occasion of various situations.
