Ascending flue and copper water jacket structure

Abstract

The invention discloses an ascending flue and a copper water jacket structure. The structure comprise a furnace body flue gas outlet, a water cooling wall and a copper water jacket, and the ascendingflue is defined by the water cooling wall, the flue gas outlet of a furnace body is in butt joint with the inlet of the ascending flue, and the size of the flue gas outlet of the furnace body is smaller than size of the inlet of the ascending flue; a copper water jacket is arranged on the inner side of the water cooling wall at the inlet of the ascending flue; the copper water jacket comprises awater tank, a bolt and a water pipe; the longitudinal section of the water tank is conical, and the horizontal section of the water tank is annular; the size of the flue gas outlet of the furnace bodyis larger than the diameter of the inner ring of the horizontal section of the water tank; and a gap between the inlet of the ascending flue and the flue gas outlet of the furnace body is filled witha non-combustible material. According to the ascending flue and the copper water jacket structure, the heat exchange area of the copper water jacket is sufficiently utilized, the efficiency is high,the cooling effect is good, and the like; and the structure of the copper water jacket is improved, the horizontal section area of the smoke dust falling in the ascending flue is reduced, smoke dust on the upper part of the ascending flue can be collected to the furnace body, and the upper ash is prevented from falling outside the furnace body, so that the sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of smelting furnaces, in particular to a flue and copper water jacket structure. Background technique [0002] During the operation of the bottom blowing furnace, the furnace body needs to keep rotating, so there must be a gap between the inlet of the ascending flue and the outlet of the furnace flue to facilitate the rotation of the furnace body. The ascending flue acts as a preliminary cooling and dust collection function for the flue gas. The dust collected by it must fall into the furnace through the flue opening for re-smelting. Secondly, the furnace body needs to be rotated, which requires that the size of the flue gas opening of the boiler be slightly larger than the flue gas of the furnace body. Export. However, a small part of the smoke and dust in the ascending flue of this structure will leak out of the furnace body. This part of the smoke and dust falling outside the furnace body not only affect...

AI Technical Summary

Problems solved by technology

[0004] 1. The size of the inlet of the rising flue of the boiler is larger than that of the flue gas outlet of the furnace body, and part of the soot from the upper part will fall outside;

[0005] 2. There is a large gap between the furnace body and the rising flue of the boiler, which is easy to leak flue gas
