Affiliated technical field

The utility model relates to by solid carbon-contg material production coal gas, water-gas, synthesis gas technical field, specifically a kind of inside and outside gasification furnace that flattens weighing apparatus.

Background technology

Gasification furnace is a kind of biomass fuels such as stalk, straw, Chai He to be burnt under anaerobic environment, thereby produces the device that imflammable gas such as carbon monoxide, methane are used again.The energy day by day the shortage today, make full use of biological renewable energy, just seem particularly important in vast rural area, mountain area.The gasification furnace of present research and development, kind is a lot, structure is different, though brought into play positive effect aspect utilizing at biomass fuel, go back ubiquity and problems such as the combustion gas conversion ratio is lower, what have has environmental pollutions such as tar peculiar smell, the unbalanced potential safety hazard that exists of the external and internal pressure that has, the once reinforced burning time later on that has is short, and flue gas is big, manipulates very inconvenient.Above-mentioned defective has influenced the popularization and the use of biomass gasifying furnace to a certain extent.

Summary of the invention

In order to solve the deficiency that existing gasification furnace exists, the utility model provides the multi-functional contamination-free biomass gasifier of a kind of combustion gas conversion ratio height, internal and external pressure balance.

The technical scheme that its technical problem that solves the utility model adopts is: this contamination-free biomass gasifier, comprise body of heater, bell, air-introduced machine and gas transmission system, said upper of furnace body is provided with vaporizer, the bottom is provided with fire grate, fire door, mainly is to be provided with the gas transmission chamber that is communicated with vaporizer by the fire grate small opening in the housing of vaporizer periphery; Top, gas transmission chamber connects first clean room by wireway, wireway is provided with the fresh wind port of band control valve, first clean room is connected with second clean room by the air entraining pipe at top and " U " type pipe of bottom, second clean room is connected by the kitchen range of gas pipeline with the band air valve, and is connected with vaporizer by " U " type return duct of its bottom; The downward-sloping setting of said " U " type return duct, its end is provided with backflash.

As a kind of improvement of the present utility model, can be provided with the medium heat radiation cover of being with media outlet, medium import at the motor of air-introduced machine and the periphery of second clean room, two media dispel the heat between the cover by being connected medium communicating pipe, so that can cool off the motor of air-introduced machine and the heat that second clean room produces fast in the gasification furnace combustion process.

The utility model major advantage compared with prior art:

The one, environmental pollutions such as no tar peculiar smell.Because the utility model adopts the Pintsch process full-closed structure, make polluters such as tar be cracked into fuel gas, not only removed pollution sources, eliminated peculiar smell, and can make these polluters be cracked into high temperature heat source once more to be utilized again, to increase substantially gas production and gaseous mass.

The 2nd, the utility model has adopted the gas balance device, makes the inside and outside pressure of body of heater reach relative equilibrium, has the unsafe factor that explodes thereby solved gasification furnace.

The 3rd, reasonable in design, easy and simple to handle, can sequencing move, make this gasification furnace become agriculture and animal husbandry family life energy source device, solve the needed thermal source fuel of daily cooking, heating, steam and plantation, plant and processing factory, for the utilization of the renewable sources of energy, the development low-carbon economy plays a part positive.
