Embodiment

[0014] Example: see figure 1 and figure 2 , a boiler shell cooling structure containing a gas distribution cavity, including a chassis, a bell-type double-layer furnace body 4 containing a jacketed cooling medium, a mirror hole, a chassis cooling water inlet pipe 1, and a chassis cooling water outlet pipe 3, A layer of gas distribution chamber 2 is arranged outside the bell-type double-layer furnace body; a certain number of ventilation holes are arranged on the jacket covered by the distribution chamber; the diameter of the ventilation holes is between φ3mm and φ8mm.

[0015] The boiler in the prior art is mainly composed of a chassis, a bell-type double-layer furnace body containing a jacketed cooling medium, a sight glass hole, a chassis cooling water inlet pipe, a chassis cooling water outlet pipe, a base cooling water inlet pipe, and a base cooling water outlet pipe. and other accessories. The main body of the furnace shell is made of stainless steel to reduce the poll...

Abstract

The invention discloses a boiler shell cooling structure with a gas distribution cavity, comprising a chassis, a bell-type bilayer furnace body containing a jacket cooling medium, a sight glass hole, a chassis cooling water inlet pipe and a chassis cooling water outlet pipe, wherein a layer of gas distribution cavity is arranged on the outer side of the bell-type bilayer furnace body; a certain amount of vent holes are arranged on a jacket covered by the distribution cavity; and the aperture of the vent hole is phi3mm-phi8mm. In the invention, gas in the distribution cavity is blown to the outer wall of an inner cylinder through the vent holes at a high speed so as to take away heat of inner cylinder metal to ensure working under a proper wall temperature; and the maximum advantage of adopting gas cooling is safe and reliable, which causes no damage on a reduction furnace and the whole operation system.

Description

Technical field: [0001] The invention relates to a boiler cooling structure, in particular to a cooling structure of a boiler shell containing a gas distribution cavity, which belongs to the field of mechanical processing. Background technique: [0002] The boiler is mainly composed of chassis, bell-type double-layer furnace body with jacket cooling medium, sight glass hole, chassis cooling water inlet pipe, chassis cooling water outlet pipe, base cooling water inlet pipe, base cooling water outlet pipe and other accessories composition. The main body of the furnace shell is made of stainless steel to reduce the pollution of equipment materials to products. During the operation, a large amount of heat is generated in the furnace, and the temperature of the furnace body can reach about 900°C, which is difficult for austenitic stainless steel to bear. Therefore, whether the casing can be sufficiently cooled to a suitable temperature directly affects the normal use of the boi...
