Description
Technical field
The utility model belongs to biogas Preparation equipment technical field, is specifically related to a kind of system utilizing stalk explosion Biogas.
Background technology
Along with fast development and the adjustment of rural energy structure of China's economy, crop residue is no longer the whole of life of farmers fuel, and the agricultural wastes of excess, how particularly stalk processes, and has become as the burden of peasant and government in recent years.A very long time in past, peasant utilizes the method for burning, is gone back fertile in field, but DeGrain, this not only wastes biomass resource, and environment be also result in pollution, in the specific period, communications and transportation and aviation safety is constituted great threat.Therefore, in fossil energy day by day deficient, today of energy form growing tension, the mankind start sight focuses on newborn energy field, and in many new forms of energy, biomass energy is considered as the energy the safest, most stable of.
China is one of agricultural production state maximum in the world, the annual all kinds of crop materials about 6-7 hundred million tons produced, comprehensive utilization makes good use of the green resource of this preciousness, advance stalk recovery energy, it is possible not only to realization turn waste into wealth, reduce environmental pollution, promotion Energy restructuring, increase farmers' income, and develop a circular economy especially, propulsion energy-saving reduces discharging, it is achieved the Important Action of low-carbon economy.
Biogas as a kind of high-efficiency cleaning energy it has been recognised that, but the biogas engineering with stalk as primary raw material is little, this is relevant with the composition of stalk and architectural characteristic, stalk is mainly cellulose, hemicellulose and lignin composition, stick to each other and be interrupted mutually, this structure is unfavorable for the anaerobic bacteria utilization to cellulose, need to pre-process it, just can apply to biomass energy source domain.And present stage, pretreatment to cellulose substances mainly has Physical, chemical method, physical-chemical process and bioanalysis, various methods emphasize particularly on different fields and pros and cons, and for anaerobic bacteria, the broken and degraded of cellulose, hemicellulose and lignin is the key factor of factor of created gase and gas production.
Steam blasting is a kind of method to cellulose substances pretreatment.Stalk is under high temperature, high steam effect, and cellulose crystallity improves, and the degree of polymerization declines, hemicellulose fraction is degraded, lignin softens, and horizontal strength of connection declines, and even softens plastic, when the material sudden pressure reduction of full steam, out of breath acute expansion in hole, produces " explosion " effect, can be partially stripped lignin, and by raw material tear for fiber fines, it is especially advantageous for hydrolyzing the contact degraded aerogenesis of bacterium and anaerobic bacteria.But certain energy can be consumed during carrying out explosion, for this, this process system, in line with the principle of cascaded utilization of energy, makes energy consumption reach to maximally utilize from links such as production technology, energy-consuming, utilizations of waste as resource, demonstrates significant economic benefit and environmental benefit.
Utility model content
For straw utilization problem present in prior art, the utility model provides the system of a kind of stalk explosion Biogas, alleviates environmental pollution, it is achieved biomass energy clean utilization.
For solve above-mentioned technical problem, the utility model by the following technical solutions:
A kind of system utilizing stalk explosion Biogas, including steam-explosion jar, described steam-explosion jar is connected with preparing pool, preparing pool is connected with screw pump, screw pump is connected with CSTR reactor, and CSTR reactor is connected with methane purifying device, and methane purifying device is connected with finished product gas holder, finished product gas holder is connected with TRT, and TRT is connected with steam-explosion jar and preparing pool respectively.
Described CSTR reactor is connected with solid-liquid separator, and solid-liquid separator is connected with preparing pool.
Described methane purifying device includes that digester and drain sump, CSTR reactor are connected with drain sump, and drain sump is connected with digester, and digester is connected with finished product gas holder.
Described preparing pool is connected with roots blower by pipeline, and preparing pool is arranged over biogas slurry return tank.
The beneficial effects of the utility model are: dry method explosion, power consumption is less, the dwell time is short, production efficiency is high, equipment Operating Management is convenient, and material flow is short, in material, waste heat loss is little, energy can recycle by step, the biogas direct generation of electricity of generation, and generating waste-heat can be as the quick-fried power of stalk vapour；Stalk after biogas slurry after separation of solid and liquid is the most quick-fried with vapour mixes, and makes the waste heat of biogas slurry have also been obtained and maximally utilizes.Through Air Exposure, in raw material, be i.e. passed through the air (aeration) of trace, side can obvious oxidative lignin, the most not only can further make the separation of lignin and cellulose, and can decompose and lignin degrading, gas production and factor of created gase can be increased substantially；Therefore, native system be a kind of low energy consumption, low operating cost stalk produce biogas novel process, thoroughly solve the problem that stalk pretreatment energy consumption is high, cost is high, its Social benefit and economic benefit is notable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of system utilizing stalk explosion Biogas, including steam-explosion jar 1, described steam-explosion jar 1 is connected with preparing pool 3, preparing pool 3 is connected with screw pump 4, screw pump 4 is connected with CSTR reactor 5, CSTR reactor 5 is connected with methane purifying device, methane purifying device includes drain sump 6 and digester 7, CSTR reactor 5 is connected with drain sump 6, and drain sump 6 is connected with digester 7, and digester 7 is connected with finished product gas holder 8, finished product gas holder 8 is connected with TRT 9, and TRT 9 is connected with steam-explosion jar 1 and preparing pool 3 respectively.
