Brick hearth type hot blast stove

Abstract

The invention discloses a brick hearth type hot blast stove. The hot blast stove comprises a horizontal plane (1), an ash removing cover (2), an underground ash pit (3), a furnace door (4), a hydrochloric acid silica alumina plate (5), a second combustion chamber (6), refractory bricks (7), a first combustion chamber (8), a feeding hole (9), a heat exchanger (10), a vent hole (11), an access hole (12), a draught fan (13) and a secondary tuyere (14); the hearth of the hot blast stove are all built with the refractory bricks, a layer of the hydrochloric acid silica alumina plate is sandwiched in the middle and used for heat preservation and insulation, and the heat exchanger is arranged on the hot blast stove; materials used by the hot blast stove are the refractory bricks or refractory bricks and common bricks. The hot blast stove has the advantages of no damage to a pipeline by permanent combustion, long service life, high combustion efficiency, easiness for repair, low manufacturing cost and easiness for popularization.

Description

technical field [0001] The invention belongs to a hot blast stove, in particular to a brick hearth type hot blast stove. Background technique [0002] With the development of productivity and the acceleration of agricultural modernization, facility agriculture has developed by leaps and bounds in recent years, among which plastic greenhouses account for a large proportion of facility agriculture. The existing hot blast stoves on the market are all welded with iron. Because the hot blast stove does not contain water, the temperature is high, it is easy to burn out, and the service life is short. Into the hot air, the hot air discharged in this way has serious pollution. Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned products, and provides a brick hearth type hot blast stove, which solves the problems that the hot blast stoves in the above-mentioned products are easy to burn out due to the lack of water, high te...
