Abstract

The utility model belonging to a solid organic waste processing device is a horizontal type mechanical biogas stirring device which employing the high concentration, plug flow biogas fermentation process (HCF). The utility model includes a horizontal type column pot body, the top of the front end of the horizontal type column pot body is arranged with a material inlet which can let the solid organic waste and the sewage in directly and not need multiple stages 'pretreatment', an agitating shaft arranged with rotating blades and a low speed motor are arranged at the medial axis of the pot body. Compared with liquid pump feeding vertical type biogas device, the utility model is energy saving, low in investment, high in gas production rate, simple in operation and low in operating cost and especially applicable to 'ecotype' biogas project which use the livestock manure as raw material.

Description

Horizontal mechanical stirs firedamp gas equipment

Technical field

The utility model belongs to the solid organic waste substances treatment unit, relates to adopting a kind of horizontal mechanical of high density, plug flow marsh gas fermentation process (HCF) to stir firedamp gas equipment.

Background technology

At present, utilize biogas fermentation technical finesse solid organic waste substances (feces of livestock and poultry and organic waste etc.), mainly adopt the vertical firedamp gas equipment of liquid pump charging.Because of being subjected to the restriction of liquid pump performance, the dry substance concentration of this device charging (TS%) can only be less than or equal to 6%, so need dissolve 2～3 times of sewage, also need multistage " giving processings " to remove the straw grass that stops up liquid pump and pipeline and feather etc. than solid substance greatly to the fermentation raw material dry matter weight.For this reason, the one, increased unnecessary sewage more than 30% and be heated to the heat energy consumption of leavening temperature (about 35 ℃ or 55 ℃), also increased the quantity discharged and the handling charges of natural pond liquid.The 2nd, multistage " giving processing " not only strengthened construction investment, also strengthened manipulation strength and running cost; Limit because of the vertical structure that is subjected to device again, the scum silica frost of removing not to the utmost constantly is deposited in the gas tank at device top, is difficult to remove and be unfavorable for the effusion of biogas; Each virgin material that adds will mix with whole old material, can cause a small amount of not fermented product of fermentation finished thoroughly1 to overflow in advance, makes its harmless treatment effect poor slightly.

Summary of the invention

Can not increase substantially the problem that input concentration and scum silica frost are difficult to remove in order to overcome the existing vertical firedamp gas equipment that adopts the liquid pump charging, the utility model provides a kind of horizontal mechanical to stir firedamp gas equipment, can make solid organic waste substances and sewage not need multistage " giving processing " and directly add, and the dry substance concentration of charging under mechanical agitation can bring up to 10%～15% from opening for feed; And the blade of rotation is constantly broken and be pressed in the fermented liquid and be removed with scum silica frost.It is a kind of churned mechanically horizontal cylinder tank body that has, in 1～8 upper spacer and 2～9 lower clapboards are arranged, a upper spacer that is less than or equal to 50 centimetres of spaces apart from the tank body top is arranged between two lower clapboards, front top has the end mouth that matches with apparatus for feeding to stretch into 30～60 centimetres opening for feed below the fermentation liquid level, opening for feed is other the water back that matches with heating installation and feed the tank body middle and lower part, gas skirt is arranged at the middle-end top, the top, rear end has end mouth to stretch into the flash pipe of following 20～50 centimetres of fermentation liquid level, the rear end end face has the residual cake valve that is lower than 50～100 centimetres of tank body axis and is positioned at the manhole of being convenient to equipment installation and checkout (EIC) on the tank body axis; Be positioned to have on the tank body axis with the stir shaft of 5～19 blades rotation and by 2～5 bearing supports and be erected on the lower clapboard, stir shaft one end docks with tank body shaft coupling and slowspeed machine outward by the sealing socket of tank body front end; Blade tip is less than or equal to 90 degree and is less than or equal to 50 centimetres with the tank body gap with the angle of tank body axis facade after the bending forward.The horizontal mechanical that the utility model proposes stirs firedamp gas equipment and compares with the vertical firedamp gas equipment of liquid pump charging, save that heat energy 30% or more, construction investment reduce 20%～30%, the raising of the factor of created gase under identical leavening temperature more than 30%, easy and simple to handle, working cost is low and the processing of suitable multiple solid organic waste substances, being particularly useful for the feces of livestock and poultry is that raw material, biogas comprehensive utilization are " ecotype " biogas engineering of purpose.

Embodiment

In the accompanying drawings, the solid fermentation raw material, the feces of livestock and poultry opening for feed 1 that can directly add particularly adds simultaneously and quantitatively dissolves sewage and drive under the stirring action of stir shafts 11 blades 10 by shaft coupling 14 and sealing socket 13 at slowspeed machine 15, is mixed into high gravity fermentation liquid.Fermented liquid is heated pipeline 3 heating, under the guiding of lower clapboard 9 and upper spacer 4, constantly wriggles to tank body 2 rear ends in upper and lower baffling mode again.The top by the stirring of bending blade under, sediment is dug to be broken with scum silica frost and to be pressed in the fermented liquid.The biogas that produces is through gas skirt 5 outputs, and natural pond liquid is overflowed automatically by upflow tube 6, and the natural pond slag is regularly discharged through residual cake valve 8.

The material of the utility model tank body 2 can be steel construction, skeleton construction or brick mix structure, and lagging facility is arranged.Concrete surfaces in the tank body 2 are all done sealing ply, must not the seepage G﹠W; All hardware is all brushed protective system.
