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

Embodiment Construction

[0016] Such as Figures 1 to 3 As shown, a bottom head of a phosphorus-burning furnace includes a skirt 1, a lower head 11 and a dish-shaped head 2 connected to the bottom of a phosphorus-burning furnace. The lower head 11 has a dish-shaped depression, and the dish-shaped head 2 Fixedly connected in the dish-shaped depression, a sealed cavity 21 is formed by the outer surface of the dish-shaped head 2 and the surface of the dish-shaped concave. The water inlet pipe 6 is connected to the bottom of the sealed cavity 21, and there is an annular water jacket on the upper end of the lower head 11. 3. The upper end of the sealed cavity 21 communicates with the annular water jacket 3 through a plurality of water outlet holes 12, and a plurality of water outlet pipes 4 are connected at the upper end of the annular water jacket 3, and each water outlet hole 12 and each water outlet pipe 4 surround the annular water jacket 3 The axes are evenly distributed. The water flows into the sea...

Abstract

A bottom head of a phosphorus-burning furnace, comprising a skirt, a lower head and a dish-shaped head connected to the bottom of a phosphorus-burning furnace, the lower head has a dish-shaped depression, and the dish-shaped head is fixedly connected in the dish-shaped depression, A sealed cavity is formed by the outer surface of the dish-shaped head and the dish-shaped concave surface. There is a water inlet pipe connected to the bottom of the sealed cavity. There is an annular water jacket on the upper end of the lower head. The upper end of the sealed cavity passes through multiple water outlet holes and annular water. The upper end of the annular water jacket is connected with a plurality of water outlet pipes, and each water outlet hole and each water outlet pipe are evenly arranged around the axis of the annular water jacket.

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...
