Description

Technical Field

[0001] This utility model relates to the field of phosphoric acid tail gas treatment technology, and in particular to a nozzle mounting structure for phosphoric acid tail gas treatment. Background Technology

[0002] As is well known, there are two main methods for producing phosphoric acid: the wet process and the thermal process. Phosphoric acid produced by treating phosphate rock with sulfuric acid and other inorganic acids is called wet process phosphoric acid; phosphoric acid produced by producing elemental phosphorus in an electric furnace or blast furnace and then hydrating it through combustion is called thermal process phosphoric acid.

[0003] Phosphoric acid tail gas treatment devices spray alkaline substances into the phosphoric acid tail gas to purify it and reduce environmental pollution. When the high-temperature phosphoric acid tail gas passes through the alkaline substances, the harmful substances in the tail gas undergo a chemical reaction under the action of the alkaline substances and are converted into non-toxic water or gas. However, the existing alkaline liquid nozzles are inconvenient to install and disassemble, which causes great inconvenience to people during maintenance. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a nozzle mounting structure for phosphoric acid tail gas treatment.

[0011] Furthermore, the inner side of the treatment tank is provided with an inclined section, and a liquid outlet pipe is connected to the inclined section, with a waste liquid collection device connected to the outside of the liquid outlet pipe.

[0012] The beneficial effects of this utility model are: by holding the lifting part and lifting the entire connecting column upward, the ball head will automatically disengage from the ball head groove. Then, the positioning part of the connecting column on the new nozzle is inserted into the first sliding groove. The position of the connecting column is adjusted by rotation so that the ball head is inserted into the ball head groove, thus completing the installation of the nozzle. The positioning part can seal the through hole to prevent air leakage. The whole disassembly is simple and easy to replace. Attached Figure Description
