Abstract
The invention discloses a straw gasification comprehensive treatment method which is characterized by comprising the following steps: processing straw into biological charcoal, purifying a mixed combustible gas generated when charcoal is prepared, and providing the purified mixed combustible gas as fuel to a metal smelting step in a casting process. The straw gasification comprehensive treatment method has the beneficial effects that the process is simple and convenient, the operation is convenient, the agriculture straw is prevented from being wasted, not only is charcoal manufactured, but also the mixed combustible gas can be obtained in the process that the charcoal is manufactured, multiple times of continuous washing with water, cooling, dust collection and tar removal ensure that the mixed combustible gas can be at the normal temperature, the tar in the gas can be removed, the combustible gas is maintained, pipelines are prevented from being blocked by tar, the environment pollution caused by charcoal manufacturing and pollution caused by coal firing and smoke discharge in the casting field are reduced, and the process cost for heating and melting metal in the casting field is reduced.
Description
Technical field
The invention belongs to charcoal coproduction field, relate to a kind of gasifying stalk integrated conduct method.
Background technology
At present, produce charcoal and will waste a large amount of timber, and after the results farm crop of rural area, remaining a large amount of stalk is settled nowhere, therefore needs to properly settle.At present, existing charcoal manufacture field, generally all the gaseous emission produced in processing charcoal process in air, the toxic gas such as carbon monoxide, sulfur monoxide that the inside is contained, not only cannot effectively utilize, and can polluted air, to human health.Melt aluminum casting industry and will use a large amount of coal, cost is high, and smog pollution is large, therefore haves much room for improvement.
Summary of the invention
The present invention in order to make up the deficiencies in the prior art, provide a kind of technique simple, easy to operate, avoid wasting raw material, cost-saving gasifying stalk integrated conduct method.
The present invention is achieved through the following technical solutions:
Gasifying stalk integrated conduct method of the present invention, it is characterized in that: comprise the following steps: utilize stalk to be processed into biological charcoal, to prepare in charcoal process and produce mixed combustible gas body, mixed combustible gas body will be purified, for the deposite metal step in casting technique provides fuel after purification.
Gasifying stalk integrated conduct method of the present invention, charcoal is prepared by charcoal barn or stalk gasifier, produce mixed combustible gas body simultaneously, by mixed combustible gas body successively through water washing type tar processor, filtering type tar processor, touch-type tar processor, essence filter formula tar processor processes, water washing type tar processor carries out first pass washing to mixed combustible gas body simultaneously, cooling, dedusting, tar removing process, filtering type tar processor carries out second time tar removing process to mixed combustible gas body, touch-type tar processor carries out second time washing to mixed combustible gas body simultaneously, cooling, dust removal process and the 3rd time tar removing process, essence filter formula tar processor carries out the 3rd time washing to mixed combustible gas body simultaneously, cooling, dust removal process and the 4th time tar removing process, make mixed combustible gas body reach normal temperature and remove tar removing and particulate contaminant.
Gasifying stalk integrated conduct method of the present invention, the reaction process of charcoal Reaktionsofen divides three sections: after biological waste is directly dropped into charcoal Reaktionsofen, first stage from be warming up to 180 DEG C, time 15-20 minute, subordinate phase temperature is 190 ~ 300 DEG C, time 15-20 minute, phase III temperature is 310 ~ 510 DEG C, time 15-20 minute, charing terminates, and obtains charcoal and mixed combustible gas body.
The mixed combustible gas body produced in charcoal Reaktionsofen reaction process comprises carbon monoxide, hydrogen.
For the deposite metal step in aluminum casting technique provides fuel after the purification of mixed combustible gas body.
The invention has the beneficial effects as follows, technique is simple, easy to operate, avoid wasting agricultural stalk, not only charcoal can be manufactured, mixed combustible gas body can also be gathered in the crops from the process manufacturing charcoal, inflammable gas is carried out continuously to the washing of some times, cooling, dedusting, tar removing, ensure that mixed combustible gas body reaches normal temperature, tar in removing gas, retain combustion gas, avoid the dry and hard obstruction pipeline of tar, the mixing liquid of isolated tar and water, because tar ratio water is lightweight, therefore can centralized collection and utilization, decrease the environmental pollution that charcoal processed causes, burn coal with casting field to smolder the pollution caused, save the process costs of casting field heat fused metal.
