Description

Three grades of desulfurizing dust-collectors

The utility model relates to a kind of deduster, three grades of desulfurizing dust-collectors of particularly a kind of coal-burning boiler, kiln special use.

Coal-burning boiler, kiln are China's main thermal hardware facilities at present, its use is wide, Coal-fired capacity is big, about 3.5 hundred million tons of year coal consumption is though played huge impetus to the development of Chinese national economy, flue dust, SO that these coal combustion equipment facilities produce in use inevitably ₂Etc. harmful substance, be the main matter of China's vast cities and towns low latitude atmosphere pollution, influence and infringement that flue dust is wherein brought for people's daily life are intuitively, easily cause people's attention, and SO wherein ₂But be cannot see, impalpable, very big to the harm of human body, but often ignored by people, the cleaner of existing most coal combustion equipment facility-specific promptly is like this.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of both dedustings is provided and can sloughs SO in the flue gas ₂Coal-burning boiler, three grades of desulfurizing dust-collectors of kiln special use.

The purpose of this utility model can realize by such technical scheme: this three grades of desulfurizing dust-collectors, it comprises having the mat woven of fine bamboo strips one and 2 two water-bath chambers of the mat woven of fine bamboo strips and the casing of a filter screen dust chamber thereafter, the upper end is communicated with air inlet pipe and the lower end exports the air entraining pipe that places bottom, the mat woven of fine bamboo strips one water-bath chamber, the upper end is communicated with top, the mat woven of fine bamboo strips one water-bath chamber and the lower end exports the air entraining pipe that places bottom, the mat woven of fine bamboo strips two water-bath chamber, be loaded on the ash discharge screw feeder of bottom, 2 two water-bath chambers of the mat woven of fine bamboo strips one and the mat woven of fine bamboo strips and be loaded on the ash discharge valve that discharges water of ash discharge screw feeder afterbody, be loaded on the annular filter screen in the filter screen dust chamber and support its up-down roller, drive the filter screen idler pulley and then drive the reductor that annular filter screen rotates, be arranged at the filter screen dedusting (operating) water nozzle in the filter screen dust chamber, the water supply tank that is communicated with the mat woven of fine bamboo strips one and 2 two water-bath chambers of the mat woven of fine bamboo strips is set, and the top of the described casing second water-bath chamber and filter screen dust chamber connect, the exhanst gas outlet of deduster is arranged at the filter screen interannular in the filter screen dust chamber, the bottom of filter screen dust chamber sets out the mouth of a river.Three grades of desulfurizing dust-collectors like this, by water supply tank to the mat woven of fine bamboo strips one and the indoor alkaline solution of packing into of 2 two water-baths of the mat woven of fine bamboo strips, and alkaline solution is flooded place the air entraining pipe lower end outlet of the mat woven of fine bamboo strips one and 2 two water-bath chambers of the mat woven of fine bamboo strips, during work, the flue gas of being discharged by coal-burning boiler, kiln not only passes through SO successively by twice bathing of the mat woven of fine bamboo strips one and the indoor alkaline solution of the mat woven of fine bamboo strips two water-baths ₂Neutralization reaction with alkaline solution and alkaline solution, reached the purpose of desulfurization, and removed wherein big thick dirt, and after entering filter screen dust chamber by the flue gas that discharge the mat woven of fine bamboo strips two water-bath chambers, by remaining little the thin dirt of annular filter screen elimination, just discharge at last, thereby finish whole desulfurization and dedusting process through exhanst gas outlet.

The above-mentioned filter screen dedusting (operating) water nozzle that is arranged in the filter screen dust chamber can be the nozzle row who is made of row's nozzle.

Three grades of above-mentioned desulfurizing dust-collectors can also dispose the motor of the annular filter screen rotation that drags in the filter screen dust chamber.

This three grades of desulfurizing dust-collectors provided by the utility model, simple in structure, efficiency of dust collection can reach more than 98%, and desulfuration efficiency can reach more than 80%, uses the coal-burning boiler of this desulfurizing dust-collector, kiln all can reach: below the soot emissions blackness Lin Geman one-level; Smoke dust discharge concentration, 150 milligrams/mark of boiler rice ³Below, 250 milligrams/mark of kiln rice ³Below; SO ₂Discharge 1430 milligrams/mark rice ³Following national dust emission standard.
