Description

A kind of stalk producer

Technical field

The utility model relates to a kind of stalk producer.

Background technology

Straw fuel gas is to utilize living beings to pass through airtight anoxia, adopts a kind of fuel gas that produces after pyrolysismethod and the heat chemistry oxidizing process, and this gas is a kind of air mixture, contains carbon monoxide, hydrogen, methane etc., also claims biogas.

Learn according to Beijing's combustion gas and gas appliance product quality supervision and inspection station straw fuel gas survey report: straw fuel gas content: carbon monoxide 15.27%, oxygen 3.12%, nitrogen 56.22%, methane 1.57%, propane 0.03%, propylene 0.05%.

The DEVELOPMENT PROSPECT of straw fuel gas is predicted in " solar energy " magazine first phase in 2003 " China's plant biomass energy development prospect " literary composition:

The plant biomass energy is a huge solar energy warehouse, is one of important " green energy resource ", can say the development and use plant biomass energy, develops solar energy exactly.The plant biomass energy can be regenerated, and is inexhaustible, inexhaustible.Therefore, according to the developing state of China's national situation and current international community " new thinking, virgin material, new technology ", the plant biomass of development is the green energy resource transformation technology of raw material, meets theme---the social sustainable development of development in this century.

It is reported, China energy expert has carried out the scientific forecasting in 3 stages to the development of first half China plant biomass energy in this century: the phase I (2001-2010), the production of the plant biomass energy can be met substantially, basic China's life in the countryside energy that solves, the energy of rupture of ecological environment is effectively controlled, the basic trend of containing the deterioration of the ecological environment that causes because of directly burn plant biomass and discarded plant living beings; Second stage: (2011-2030), China's rural area plant biomass Integrated Energy construction reaches socialization, agricultural plant biomass energy mode multidimensional, diversification, produce, life is with being met, plant biomass green energy resource transformation technology obtains general promotion and application, and I begin to go on eucyclic track with improvement of the ecological environment; Phase III: (2031-2050), set up China and provide multiple forms of energy to complement each other, plant biomass production of energy supply system rational in infrastructure, safe and reliable, and formation scale, township enterprise is because of high efficiency of energyization, and the peasant is because of energy high quality.Substantially set up the eucyclic ecological environment system engineering that adapts to sustainable development, strengthen the capability of sustainable development that China's plant biomass Integrated Energy is built.

The famous scientist of China, academician professor Zhu Qingshi of the Chinese Academy of Sciences say that China's energy strategy presses for research and makes raw material production liquid type, gas fuel with non-grain biolobic material at present.Develop to have and independently know the practical technique of knitting property right and having promotional value, ensure the security development utilization and the economic prosperous prosperity of China's plant biomass energy.

The peasant uses the straw fuel gas can be from following two aspects, and the first, obtain by gasifying stalk engineering central gas supply.The second, can utilize living beings oneself to produce.

The gasifying stalk engineering is generally country, and the individual tripartite investment of collective is built together, and the gasification engineering in a village (referring to the village that peasant household lives and concentrates) approximately needs 50-80 ten thousand, in present nearly more than 200 the at village level gasifying stalk engineerings of China.

The self-produced personal straw fuel gas of peasant mainly carries out living beings by the family expenses producer and transforms, and investment is little, and is little then surplus in the of 300 yuan, at most surplus in the of 700 yuan.

Carbon mass fraction in the plant biomass (comprising according to wood, firewood, weeds, pine needle leaf, crop material, cattle and sheep animal manure, edible fungi residues) is about 40%, is elements such as hydrogen, nitrogen, oxygen, magnesium, silicon, phosphorus, potassium, calcium secondly.The organic principle of straw is with cellulose, and hemicellulose is main, and mass fraction is 50%.These biomass materials heat under anoxia condition, make it to take place the energy conversion process of complicated thermal chemical reaction.This process nature is to plant atoms of elements such as carbon in the matter, hydrogen, oxygen, according to the one-tenth key principle of chemical bond, becomes the molecule of imflammable gas such as carbon monoxide, methane, hydrogen under reaction condition.Most of energy in the plant biomass is just transferred in these gases like this.

Producer has biomass raw material gas making, gas-purification, automatic function of separating.When dropping into the burner hearth internal combustion, fuel produces a large amount of CO and H ₂The time, combustion gas imports automatically that piece-rate system is carried out detar, taken off flue dust, the decontamination procedure of dehydration steam, thereby produces the high-quality combustion gas, and combustion gas is transported to gas furnace by pipeline, lights and can use.
