Suspend by cyclone separator bottom collection, but also a small amount of micronic dust shape is suspended in drying tower room, and this partial suspended thing cannot be received
Collection.Such as it is directly discharged in air that air pollution can be caused without process.
The content of the invention
The utility model provides a kind of polyaluminium chloride tail gas energy-saving emission-reducing apparatus, the device pair according to the deficiencies in the prior art
Taken out of in the air for leaving hothouse containing AL (OH)3+ HCL compositions be dried suspension must effectively be separated and return
Receive, the yield of polyaluminium chloride not only can be improved, be also prevented from powder and to escape to cause in air air pollution.
The technical scheme that the utility model is provided：Tail gas energy-saving emission-reducing apparatus during a kind of production polyaluminium chloride, including
Spray scrubber, air-introduced machine, washing lotion pond and exhaust chimney, the spray scrubber is arranged on the blast pipe of cyclone dust collectors,
The dusty gas import of spray scrubber is connected with the exhaust outlet of cyclone dust collectors, and the exhaust outlet of spray scrubber passes through blast pipe
Connect with exhaust chimney, the discharge machine is arranged on the blast pipe between spray scrubber and exhaust chimney；The washing lotion pond
It is arranged at the sewage draining exit of spray scrubber, and connects with the sewage draining exit of spray scrubber.
The utility model preferably technical scheme：The spray scrubber is double layers of sprinkling scrubbing tower, including tower body and is followed
Ring water system, the tower body is divided into upper and lower two-layer, and in every layer of tower body spray system is equipped with.
Energy-saving emission-reducing apparatus described in the utility model increase after cyclone separator, are dried finished product big with air mixture
Part separates from drying tower bottom internal cyclone and cyclone separator is entered back into after discharging, and finished product dry powder is by bottom of towe and cyclone separator bottom
Collect, the waste gas containing a small amount of micronic dust will be entered in spray equipment of the present utility model and arranged by air-introduced machine after udst separation
Enter air；Waste gas into a small amount of micronic dust after spray equipment is mixed to form waste water with shower water, when waste strength (solid content)
When reaching 15%, washing lotion pond is recycled to again, after washing lotion pond is washed, solids is collected into feed flow precursor reactant dispensing and is used.
The utility model simple structure, it is easy to use, can be to being taken out of in the air for leaving hothouse containing AL (OH)3
+ HCL compositions are dried suspension and must effectively be separated and be reclaimed, it is ensured that dry run can obtain PAC (polyaluminiums
Aluminium) maximum production, improve the yield of polyaluminium chloride, it is thus also avoided that powder is escaped to and cause in air air pollution, reaches waste water
Recycle and reuse and environment protection, energy-conservation, reduction of discharging, environmental protection.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1-spray scrubber, 1-1-dusty gas import, 1-2-sewage draining exit, the row of 1-3-spray scrubber
