Description

A kind of stalk goes mouldy exothermic circular response device and application method
Technical field
Of the invention and a kind of stalk goes mouldy exothermic circular response device and application method, belongs to energy reaction technology neck Domain.
Background technique
Nearly 1,200,000,000 tons of China's agricultural crop straw annual output in 2018.Stalk is valuable renewable biomass resources, is had Higher energy density, the calorific value of stalk are about 19MJ/kg, are equivalent to 0.65 times of standard coal.But with economic development and work The demand of the propulsion of industry, stalk reduces rapidly, and the stalk more than 65% is discarded or burned, therefore causes serious money Source waste and environmental pollution.In the north, the bring atmosphere pollution of burning wantonly of stalk has become what winter and spring haze took place frequently Main cause.Therefore, the high-efficiency cleaning of stalk resource utilizes the hot spot for having become numerous experts and focus of attention.
The northern area of China, which is burned about 200,000,000 tons every year and dissipated, burns coal, and which results in severe air pollution and energy wastes.And In the composting technology of traditional agriculture, stalk can contamination-freely be discharged thermal energy by the decomposition that goes mouldy, and pile core temperature is up to 50-90 ℃.But since the mildew exothermic process of stalk under natural conditions is excessively slow, this partial heat energy is not utilized efficiently, big absolutely Majority is lost in environment.If the composting technology based on traditional agriculture, and improved, the thermal energy of stalk mildew release is used It heats in rural area, can reduce to dissipate and burn burning of coal, to mitigate atmosphere pollution.However, there is no a kind of can efficiently utilize at present The thermal energy of stalk mildew process release and the technology to heat for rural area.
Composting process usually needs good ventilation and temperature control, provides advantageous condition for mildew.But currently, large scale industry Change compost often to need manually to blow to realize the tune of temperature by the device of the complexity such as external heat source or water-bath to meet ventilation condition Control, technical costs are higher.
Summary of the invention
To solve the problems in the background art, the present invention provide a kind of stalk go mouldy exothermic circular response device and Application method.
Realize that above-mentioned purpose, the present invention take following technical proposals: a kind of exothermic circular response device of stalk mildew, packet It includes top cover, reactive tank, threaded rod, handle, multiple supporting plates and three partitions, the top cover and is co-axially located at the upper of reactive tank End, top cover are fixedly connected with the upper end of multiple supporting plates and are equipped with multiple through-holes, the middle part of top cover and the threaded rod spiral shell being vertically arranged Line rotation connection, the upper end of the threaded rod are fixedly connected with handle, are fixedly connected in the middle part of the lower end of threaded rod and reactive tank, The inside of the reactive tank by center to inner sidewall fixed setting there are three partition, three partitions with the lower end of threaded rod It is fixedly connected.
The exothermic circular response device of a kind of stalk mildew of the invention and application method, method include the following steps:
Step 1: three reaction compartments are respectively labeled as reaction compartment one, reaction compartment two and reaction compartment three;
Step 2: stalk is put into reaction compartment one;
Step 3: swing handle drives reactive tank rotation by threaded rod, makes the distance between reactive tank and top cover needed for, And additive is instilled into reaction compartment one by the corresponding through-hole of reaction compartment one, start the stalk in reaction compartment one just The mildew reaction in mildew stage phase;
Step 4: corresponding logical again by reaction compartment one after the stalk in reaction compartment one completes initial stage mildew reaction Hole instills additive and the bacterium solution containing cellulose hydrolysis bacterium Jing Guo enrichment culture into reaction compartment one, makes reaction compartment Stalk in one starts the mildew reaction in the stage of mildewing;Stalk is put into reaction compartment two simultaneously, and passes through reaction compartment two Corresponding through-hole instills additive into reaction compartment two, and the stalk in reaction compartment two is made to start the mildew in mildew stage at initial stage Reaction;
Step 5: after the mildew reaction in stage is mildewed in the stalk completion in reaction compartment one, straw are put into reaction compartment three Stalk, and additive is instilled into reaction compartment three by the corresponding through-hole of reaction compartment three, make the stalk in reaction compartment three The mildew reaction in mildew stage at beginning initial stage;After the stalk in reaction compartment two completes initial stage mildew reaction, again by anti- It answers the corresponding through-hole in space two to instill additive into reaction compartment two and contains cellulose hydrolysis bacterium by enrichment culture Bacterium solution, make the stalk in reaction compartment two start the stage of mildewing mildew reaction;
Step 6: it after the stalk in reaction compartment one completes the mildew reaction in mildew and rot stage, is drawn off, and be put into new straw Stalk repeats the correlation step of above-mentioned reaction compartment one;The stalk in reaction compartment two starts the mildew reaction in mildew and rot stage at this time, Additive is instilled into reaction compartment three and by enrichment culture containing fibre by the corresponding through-hole of reaction compartment three simultaneously The bacterium solution for tieing up plain hydrolytic bacteria makes the stalk in reaction compartment three start the mildew reaction in the stage of mildewing;
Step 7: it after stalk completes the mildew reaction in mildew and rot stage in reaction compartment two, is drawn off, and be put into new straw Stalk repeats the correlation step of above-mentioned reaction compartment two;The stalk mildew of reaction compartment three was reacted to the mildew and rot stage at this time;
Step 8: it after stalk completes the mildew reaction in mildew and rot stage in reaction compartment three, is drawn off, and be put into new straw Stalk repeats the correlation step of above-mentioned reaction compartment three.
Compared with prior art, the beneficial effects of the present invention are:
1, the present invention realizes the adjusting control of heat transfer and ventilation by the adjusting to gap between top cover and reactive tank, when turning When dynamic threaded rod moves upwards reactive tank, the gap between top cover and reactive tank becomes smaller, and then weakens ventilation, reduces heat transfer, Be conducive to the rising of temperature;When rotating threaded rod moves downward reactive tank, the gap between top cover and reactive tank becomes larger, after And accelerate ventilation, heat transfer rises, be conducive to thermal energy release and gas circulation convenient for according to flora to the inclined of gas and temperature It is good, it realizes the adjusting of environmental condition, then promotes mildew rate;Meanwhile by different phase to mildew be added additive and By the bacterium solution containing cellulose hydrolysis bacterium of enrichment culture, enhance the hydrolysis efficiency to cellulose, it is mould further to promote stalk Become the rate of reaction;
2, the present invention improves the status that stalk is largely discarded by most of organic matter in mildew decomposing straw, realizes stalk The efficient utilization of resource, while reducing because of atmosphere pollution caused by dissipating burning coal and straw burning.Often it is only Heilongjiang Province Reduce by 16.3 ten thousand tons of PM2.5 discharge, serious pollution number of days reduces 70% or so;
3, the present invention realizes inexpensive, the efficient utilization to stalk;Required raw material is mainly stalk, additive and water, raw material Cost is relatively low;This technology is not necessarily to special equipment, and technical costs is lower, easy to spread.
4, straw decomposition product returning to the field is beneficial to promote soil fertility by the present invention.The thorough decomposition of stalk can release original The nitrogen of stalk quality 52%, 90% P elements and 57% potassium element.
