Radiant waste-heat steam generator for tunnel brick kiln

Abstract

The invention relates to a radiant waste-heat steam generator for a tunnel brick kiln, which comprises a radiant evaporator pipe bank, a radiant superheater pipe bank, a rising header pipe, a descending header pipe, a riser pipe, a downcomer and a steam accumulator; a plurality of the radiant evaporator pipe banks and a plurality of the radiant superheater pipe banks constitute a heat-transfer surface, the radiant evaporator pipe banks and the radiant superheater pipe banks are arranged in a staggered manner, the radiant evaporator pipe banks are rear-mounted, and the radiant superheater pipe banks are front-mounted; an inlet and an outlet of the radiant evaporator pipe bank are connected to one end of the rising header pipe and one end of the descending header pipe respectively, and the other end of the rising header pipe and the other end of descending header pipe are connected to the steam accumulator; and an inlet of the radiant superheater pipe bank is connected with a steam outlet of the steam accumulator, and high-temperature superheated steam is drained from an outlet of the radial superheater pipe bank. The radiant waste-heat steam generator for the tunnel brick kiln has the advantages that the cooling rate of bricks can be increased, the production efficiency can be improved, meanwhile, a lot of radiant heat of 900-1000 DEG C released from the fired bricks is recovered, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to waste heat recovery and cooling treatment equipment for industrial furnaces, in particular to a tunnel type brick kiln radiation waste heat steam generator. Background technique [0002] After the bricks are fired in the tunnel-type brick kiln, a large amount of high-temperature radiant heat is released (the temperature of the radiant heat released after the bricks are fired can reach above 900-1000°C). The traditional cooling method is natural cooling of bricks. This method not only wastes a large amount of high-temperature heat released by cooling bricks, but also has a slow cooling rate, which is not conducive to the continuous production of brick kilns. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a tunnel-type brick kiln radiant waste heat steam generator, which can not only cool down the fired high-temperature bricks...
