Dynamics gasification furnace and exhaust heat boiler composed by the same

Abstract

The invention discloses a dynamic gasification furnace and a waste heat boiler formed by the dynamic gasification furnace and relates to gasification equipment using solid fuel to produce synthesis gas. The invention has wide raw material suitability, and the raw materials comprise original msw, biomass, bio-coal briquette, coal-based briquettes, raw coal and loose coal. Through applying the invention, garbage and biomass gasification equipment with low investment, simple operation and easy popularization can be designed, can be operated as conventional boilers and can realize continuous raw material input, continuous deslagging and continuous synthesis gas output. The invention contributes to the active utilization of renewable energy, solves the problem of the treatment of domestic garbage and agricultural and agricultural and forest residues, ensures that the domestic garbage and agricultural and forest residues are transformed into clean energy, on one hand, the problem of environmental protection is solved, on the other hand, the situation of energy crisis is alleviated, creates conditions for promoting the overall coordinated and sustainable development of the economic society, and creates good development chance for rural areas which provide biological resources.

Description

Technical field

[0001] The invention relates to a gasification device, in particular to a gasification device for producing syngas by using solid fuel. Background technique

[0002] At present, the global energy is becoming increasingly tense and the environmental protection situation is becoming increasingly severe. For our country, on the one hand, we have to import a large amount of oil and liquefied gas from abroad every year, but on the other hand, the abundant garbage and biomass resources have not been effectively utilized. Most of it is discarded or incinerated, and some places are even overflowing with garbage. With the development of my country's national economy and the continuous expansion of urban scale, garbage will also increase by 10%, and its content of harmful components is also getting higher and higher. If it is not handled properly, it will pollute the environment and affect people's health. Life. At present, most areas in my country still use the landf...

Embodiment Construction

[0019] figure 2The illustrated embodiment is one of the gasifiers of the present invention, the equipment mainly consists of a drum (5), a heat receiver (9), a heat exchange chamber (10), a dynamic heat-gathering air duct (11), a dry distillation Pyrolysis zone (25), embers zone (15), fire grate (23), air distribution chamber (19), damper (20), steam nozzle (22), slag cooling chamber (17), induced air fan (30), feed bin (28), thermal insulation enclosure body (31), housing (32) form. Among them: the entrance of the dynamic heat-gathering air duct (11) has a swirl chamber (12) and a swirler (21); the dry distillation pyrolysis zone (25) communicates with the burnout zone (15) to form a combustion gasification furnace There are dechlorination / desulfurization agent (27) and reflective drying (26) above the dry distillation pyrolysis zone (25); the top of the burnout zone (15) is a cyclone (21), a cyclone chamber (12), and the cyclone The top of the flow chamber (12) is the dyn...
