Abstract

The invention discloses a biomass combustion gas production method, which comprises the following steps: crushing, gasifying, dedusting, cooling and purifying to obtain combustion gas; purifying step is carried out by employing a tar catalysis cracking process, a catalyst is dolomite with diameter of 3mm-5mm, and temperature during the cracking process is controlled between 850-950 DEG C. The biomass combustion gas production method has the advantages of high output and no secondary pollution, and is suitable for usage of production line with large body weight.

Description

A kind of biological fuel gas production method
Technical field
The invention belongs to new energy field, particularly a kind of method utilizing biomass energy to be converted into combustion gas.
Background technology
Biomass mainly refer to the material such as fowl and animal excrement and waste in the lignocellulose such as stalk, trees, farming industry tankage, agriculture and forestry organic waste material and the Animal husbandry production process in agroforestry production process except grain, fruit.Representational biomass are as farm crop, agricultural waste material, timber, timber waste and animal excrement.Biomass have the feature of recyclability, low stain.The equipment that the combustion gas prepared after gasifying biomass be can be used for various use combustion gas is used for energy supply.How Wood Adhesives from Biomass being become can be people's research direction in this year for the combustion gas of user.Especially gas cleaning process wherein, because biomass fuel can produce a lot of tar in gasification, the general mode adopting washing now, combustion gas is passed in water, tar is stayed gas clean in water and is flowed out, and both reduces system efficiency, produces again the sewage containing tar, supporting a large amount of water just can complete cleaning task, will inevitably produce serious secondary pollution like this.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of biological fuel gas generation method, utilizes washing tar to produce the problem of secondary pollution for solving existing biological fuel gas.
Technical scheme: for achieving the above object, present invention employs following technical scheme:
A kind of biological fuel gas production method, obtains combustion gas after sequentially passing through pulverizing, gasification, dedusting cooling, purification; Described purification adopts catalytic cracking of tar method to carry out.
As preferably, in the present invention, the catalyzer adopted in catalytic cracking of tar process is rhombspar, and in cracking process, control temperature is greater than 850 DEG C.
As preferably, in the present invention, the diameter of described rhombspar is 3mm ~ 5mm.
Beneficial effect: the production method of biological fuel gas of the present invention is applicable to fairly large production line, production process China adopts the mode of catalytic cracking of tar to carry out the removal of tar, and utilization of waste material, by the gas that tar conversion is similar to the composition of gasifying gas, not only reduce carbon black and add total tolerance and improve production capacity, killing two birds with one stone.
Embodiment
A kind of biological fuel gas production method, obtains combustion gas after sequentially passing through pulverizing, gasification, dedusting cooling, purification; Described purification adopts catalytic cracking of tar method to carry out, and catalyzer is diameter is the rhombspar of 3mm ~ 5mm, and in cracking process, control temperature is between 850 DEG C ~ 950 DEG C.
Wherein, biomass gasification process is heated by biomass material, makes the organic hydrocarbon compounds cracking with higher molecular weight, become CO, H of lower molecular weight 2, CH 4deng inflammable gas.Because biomass material itself is by element and ash compositions such as carbon, hydrogen, oxygen, when they are lighted, only supplies a small amount of air, and control its reaction process, make carbon, protium is changing into CO, H 2, CH 4deng composition flammable other, then the most of energy in biomass has all been transferred in gas, realizes gasification.
Then through dedusting cooling, the grey matter in gas is removed, but tar still exists, now the temperature of gas also correspondingly reduces, in order to remove tar, gas is passed in scission reaction stove, and in stove, be evenly covered with rhombspar gas is fully contacted with catalyzer, especially suitably arrange rhombspar in the entry position of scission reaction stove more, tar content is herein especially many, promotes more than the temperature to 850 DEG C of scission reaction stove simultaneously, finally controls between 850 DEG C ~ 950 DEG C.Gas enters scission reaction stove, only needs 1s can reach goudron lysis rate and reaches 99%, efficiently fast.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.

Claims (3)
