Furnace bottom sealing head for phosphorus burning furnace

Abstract

The invention relates to a furnace bottom sealing head for a phosphorus burning furnace. The furnace bottom sealing head for the phosphorus burning furnace comprises a skirt seat, an upper sealing head and a disc-shaped sealing head connected onto the bottom of the phosphorus burning furnace, wherein the lower sealing head is provided with a disc-shaped recessed part; the disc-shaped sealing headis fixedly connected into the disc-shaped recessed part; the outer surface of the disc-shaped sealing head and the surface of the disc-shaped recessed part form a sealed cavity; the bottom of the sealed cavity is communicated with a water inlet pipe; an annular water sleeve sleeves outside the upper end of the lower sealing head; the upper end of the sealing cavity is communicated with the annularwater sleeve through a plurality of water outlet holes; a plurality of water outlet pipes are communicated with the upper end of the annular water sleeve; each water outlet hole and each water outletpipe are uniformly distributed around the axial line of the annular water sleeve.

Description

technical field [0001] The invention relates to a bottom head of a phosphorus-burning furnace, which belongs to the field of chemical production. Background technique [0002] The phosphorus-burning furnace (DHS10-1.0-P) is a chemical equipment that burns yellow phosphorus to produce phosphorus pentoxide. Now the disc-shaped head at the bottom of the phosphorus-burning furnace has the following problems: [0003] 1. The natural pressure is too high: due to the cooling method of the dish head of the original phosphorus-burning furnace, a main water inlet pipe enters the central water pipe of the dish head, and the outlet water returns to the top of the 14-meter-high phosphorus-burning furnace, so that the dish head The natural water pressure reaches 1.4 kilograms per square centimeter. [0004] 2. The local steam generated by the disc-shaped head is not easy to discharge: due to the uneven water outlet and poor exhaust, the disc-shaped head is easy to generate local steam, a...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the shortcomings of the existing dish-shaped head that the natural pressure is too high and the local steam generated by the dish-shaped head is not easy to discharge, and a bottom head of a phosphorus-burning furnace is designed. Prevent steam lock phenomenon, and reduce the natural pressure of cooling water by reducing the height of cooling return water
