Environment-protecting and energy-saving reverse discharge type biomass gasifier

Abstract

The invention discloses an environment-protecting and energy-saving reverse discharge type biomass gasifier. The biomass gasifier comprises a furnace body, wherein a feed port is formed in the side surface of the furnace body; a stove tabletop is arranged above the furnace body; the lower side of the furnace body is mounted on a furnace base; a hearth is arranged in the furnace body, and comprises a primary combustion chamber arranged at the lower part and used for burning a solid or biomass fuel and a secondary combustion chamber arranged at the upper part and used for burning combustible gas generated by burning the solid or biomass fuel; water is arranged in the furnace base for removing particles in burning smoke; and the furnace base exhausts smoke filtered by the water outdoors through a flue. The biomass gasifier can sufficiently burn the fuel, and reduces harmful gas generated by insufficient combustion of the solid fuel and the biomass fuel; and meanwhile, the smoke generated by secondary combustion enters the water in the furnace base through a smoke circulating channel, the particles in the smoke are filtered by the water, and the smoke is exhausted outdoors by the flue connected with the furnace base, so that the purposes of energy conservation and environmental protection are achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of heating furnaces, and relates to a household biomass gasification furnace, in particular to an environment-friendly and energy-saving reverse exhaust biomass gasification furnace. 【Background technique】 [0002] At present, the stoves on the market are generally direct combustion and add catchy secondary oxygen supply technology, and the smoke emission is physical emission. The existing combustion method is mainly due to insufficient combustion. Although the emission standard can meet the emission standard formulated by the state, it is still not satisfactory for air pollution. Due to the direct discharge of smog, the heat energy produced by it cannot be fully utilized, and it will be wasted when the smog is discharged, and the heating effect is not ideal. Therefore, it is extremely important and urgent to invent a high-efficiency, energy-saving and low-emission heating stove. 【Content of invention】 ...
