QUARTZ FILTER FOR CONTINUOUS CLEANING orthophosphate solution with ammonia at capture ammonia from the coke oven gas continuous phosphate process

摘要

The invention relates to the coking industry namely, to capture the ammonia from coke oven gas phosphate circular manner and relates to quartz filters for continuous cleaning solutions of ammonium orthophosphates of tarry substances. Quartz filter for continuous cleaning solutions of ammonium orthophosphates comprises a cylindrical body with a nozzle for supplying a cleaning solution, a pipe for discharging the purified solution, a pipe for removing resinous substances stocked in the bottom of quartz sand, inside which there is an air-lift pump, consisting of a vertical riser pipe, lowered the lower part in the quartz sand pipe for supplying compressed air to the bottom of the riser, the lift tube in the upper part is provided with a replaceable nozzle Placed in the shell with the flange and the upper portion of the nozzle is located above the nozzle for discharging the purified solution. When using the proposed utility model achieved complete cleaning quartz sand of resinous substances in the riser airlift pump, removal of resinous materials from the crystal filter as a marketable product. 1 yl.
