Abstract

The continuous dry fermenting methane generating pool has main body comprising a fermenting pool and a slag pool of reinforced concrete structure. It has one material stirring and pushing device connected to the feeding port, one slag stirring wheel in the slag outlet, one deflecting overflow pipe for assisting slag discharging, heating steam pipes, methane outlet in the upper part, material level observing windows and a temperature testing instrument inside the pool. The present invention is one continuous dry fermenting methane generating apparatus with high methane concentration, and has low power consumption, reasonable structure, great treating amount, effective temperature maintenance and other advantages.

Description

Continuous dry fermenting mathane generating pool

Technical field: the present invention relates to the marsh gas fermentation pool in a kind of bioenergy field, is a kind of continuous dry fermenting mathane generating pool specifically.

Background technology: now domestic biogas generating device though have some large methane tanks, also is that the prototype in small-sized methane pond is amplified mainly based on little biogas, and its principal feature is as follows:

What 1, traditional methane-generating pit technology adopted is wet zymotechnique, and solid content is low, and material concentration generally only moves between 5-8%, and production efficiency is low.

2, wet fermentation power consumption is high, and summer, power consumption was that self is energy-producing more than 30%, and winter, power consumption was that self is energy-producing more than 50%, and this has just limited ordinary production and the energy utilization of biogas at north of china in winter greatly.

3, pond, wet type biogas pond body is vertical circle, and the charging and the flow process of slagging tap are poor, and digestibility is low, also has difficult problems such as insulation difficulty, the husky difficulty of row and natural pond, top slag knot lid to fail to solve.

Biogas technology situation abroad, it is external general that what adopt is " intermittent type is done fermentation " biogas technology, and the total technical feature of this technology is higher, and production efficiency is also higher, but facility investment is big, and the working cost height is so popularization and application is restricted.

Summary of the invention: the object of the present invention is to provide a kind of continuous dry fermenting mathane generating pool; it can improve material concentration and reach about 25% operations; but continuous dosing is slagged tap continuously; have advantages such as treatment capacity is big, flow process stable, high, the continuous operation of digestibility, insulation convenience, can satisfy the large-scale production requirement.

Technical scheme of the present invention is as follows:

This mathane generating pool main part is by fermentation vat and go out slag bath two portions and forms, and the pond body is that Steel Concrete is built, and the fermentation vat front end is established a pusher and stirred wheel, and fermentation vat bottom leading portion is made as ramp type, and the ratio of slope is 1: 3--5, back segment are that platybasic type is in order to the increase volume; Front end is opened an opening for feed apart from top low level place, the external wheel material-pulling device that stirs; Rear end below has slag notch, external natural pond slag bath, and oblique arrangement one is carried slag and is stirred wheel in the slag bath of natural pond, and the natural pond slag bath opens in addition that a deflector type upflow tube is auxiliary slags tap simultaneously; At each section of methane-generating pit every setting up steam heating tube separately to set a distance; The methane-generating pit top is set up several methane outlets separately; Material level line position both sides at fermentation vat are provided with the material level visor, in single side face temperature measuring device are set.

The above-mentioned fermentation vat charging leading portion top certain altitude that will descend is as between the sealing binder, to play the effect of binder and sealing biogas.

Above-mentioned fermentation vat charging leading portion is established a current-sharing rhombus column in the middle of stirring wheel mouthful position, advances in order to material balance.

Above-mentioned heating tube is contained in the built-in fitting, and built-in fitting and water back all are that the glass reinforced plastic material is made, so that reach the permanent use of facility.

The invention has the advantages that: 1, this device solves one do fermentation continuity production problem, material concentration can move about 25%, day an inlet amount be methane-generating pit volumetrical about 1/20, every cubic capacity day can be produced biogas 2M ³About, improving about 3 times than vertical wet ferment biomass pool concentration, slag water ratio in natural pond is low in addition, is convenient to natural pond slag production composite fertilizer operation.2, dried fermentation power consumption is low, only is about 15% of self-produced energy in north power consumption in summer, and winter, power consumption was about 25% of self-produced energy, and is supporting with methane boiler and solar energy equipment, can guarantee the operation of north of china in winter ordinary production.3, this methane-generating pit is the continous way rectangular structure; by fermentation vat with go out slag bath two portions and form; one endfeed one brings out slag; inside does not have other mechanical facility; have rational in infrastructure, advantages such as treatment capacity big, the insulation convenient, flow process is stable, digestibility is high, continuous operation, can satisfy the large-scale production requirement.

Description of drawings: Fig. 1 is an one-piece construction diagrammatic cross-section of the present invention;

Fig. 2 is a vertical view of the present invention.

Embodiment: the invention will be further described below in conjunction with accompanying drawing.

Can be seen that by Fig. 1, Fig. 2 this mathane generating pool main part is by fermentation vat 3 and go out slag bath 8 two portions and form, the pond body is that Steel Concrete is built, the fermentation vat front end is established a pusher and is stirred wheel 1, and fermentation vat bottom leading portion is made as ramp type, and the ratio of slope is 1: 4, back segment is flat, so that increase volume; Front bottom end is opened an opening for feed, and external steel stirs wheel material-pulling device 1; Rear end below has slag notch 7, and external natural pond slag bath 8 obliquely in the top position of natural pond slag bath is provided with one and carries slag and stir wheel 9, mixes in addition to establish a deflector type upflow tube and use as auxiliary deslagging again; Fermentation vat leading portion top to descend certain altitude as the sealing binder between 10, with play binder and the sealing biogas effect; Centre bit at this section installs a current-sharing rhombus column 2 simultaneously, helps material balance and advances; Set up steam heating tube 4 separately at each section of methane-generating pit, this pipe is that glass reinforced plastic is made, and it is the material level visor that the methane-generating pit top is set up several methane outlets 5,11 separately, and the side also has temperature measuring device; 6 is warming plate and Heat insulating protective wall.
