Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of pulling flow type preatreating reactors, comprises housing 1, rabbling mechanism, heating arrangements and mechanism 4 of removing sand.Housing 1 is horizontal hollow columnar structures, and its internal cavities is as reaction compartment.Housing 1 is provided with charging aperture 101 and discharging opening 102; Charging aperture 101 is arranged on the top of housing 1 one end.The other end of housing 1 is provided with discharging opening 102, and after acidifying, material is sent in biogas fermentation tank body by discharging opening 102 under the driving of dynamical system (being generally pump).Position near charging aperture 101 on housing 1 is also provided with concentration adjustment mouth 103.This concentration adjustment mouth 103 is connected with natural pond liquid reflux line and fresh water (FW) pipeline, by the natural pond liquid of backflow or the concentration of fresh water (FW) adjustment raw material.For ease of maintenance, position suitable on housing 1 is also provided with manhole 104.
Rabbling mechanism comprises the shaft 201 being arranged at housing 1 inside and the helical blade 202 be arranged on described shaft 201; Helical blade 202 is distributed in the circumference of shaft 201, and helical blade 202 is not parallel with the normal section of shaft 201.The normal section of shaft 201 refers to the cross section perpendicular to shaft 201 axis direction.So, the set-up mode of helical blade 202 is similar to the flabellum mounting means of electric fan, and when shaft 201 drives helical blade 202 to rotate, helical blade 202 has more large area and stirs raw material on the one hand, improves the efficiency of stirring; On the other hand, the rotation of helical blade 202 can make raw material moving along shaft 201 axis, makes raw material mix further.
In the present embodiment, the position of charging aperture 101 and discharging opening 102, respectively near the two ends of described shaft 201, is conducive to stirring abundant homogenize.The spacing of helical blade 202 on shaft 201 diminishes to discharging opening 102 direction gradually from charging aperture 101.This design can ensure that mixing completely of material also can, by comparatively heavy sand and feed separation, cause sand to be deposited in bottom housing 1.Shaft 201 is driven by drive unit 204, and for the ease of sediment deposition, shaft 201 rotating speed is comparatively slow, is set as 1r/min in the present embodiment, also can changes according to actual conditions.Although low-rotate speed is unfavorable for material homogenize, the helical blade 202 of the utility model uniqueness arranges and solves this problem, has taken into account material homogenize and sediment deposition two techniques simultaneously.
Mechanism 4 of removing sand comprises the groove and be arranged on the screw rod (not shown) of removing sand of removing sand in groove of removing sand being arranged at housing 1 intracavity bottom; The screw rod that removes sand is parallel with above-mentioned shaft 201, and the screw rod that removes sand is driven by dynamical system.In the present embodiment, the groove that removes sand is the structure forming sealing on being welded on bottom housing 1 opening by angle steel, also as required remove sand groove and housing 1 can be made integrative-structure.The groove that removes sand is provided with near one end of discharging opening 102 mouth 403 that removes sand.The silt being deposited on housing 1 intracavity bottom moves to the mouth 403 that removes sand under the effect of the screw rod that removes sand, and discharges inner chamber by the mouth 403 that removes sand.
As shown in Figure 2, heating arrangements comprises heat(ing) coil 301 and the heat-insulation layer 3 be attached to outside housing 1.Heat-insulation layer 3 can prevent from reducing thermal loss, contributes to ensureing the efficiency of heating surface.Heat-insulation layer 3 is provided with zone of heating 302 near the part of housing 1, and heat(ing) coil 301 is arranged in zone of heating 302.Heat(ing) coil 301, as main heating source, can provide heat.Zone of heating 302 structures as a centre, are full of water or conduction oil in layer, its Main Function is the heat from heat(ing) coil 301 to carry out homogenize, and make even heat scatter housing 1 surface, homogeneous heating, avoids hot-spot.
In the present embodiment, housing 1 is formed by Plate Welding, and its structure is one cylindrical, and cylindrical interior space is the pretreatment space of raw material.This housing 1 is supported in more than ground by supporting leg, and housing 1 is provided with one end absolute altitude one end higher than discharging opening 102 of charging aperture 101, this ensure that the raw material of high concentration can move from charging aperture 101 end to discharging opening 102 end.
The course of work of the present embodiment is as follows:
Raw material drops into housing 1 inner chamber by charging aperture 101 by pump or helical feed, and open concentration adjustment pipeline according to the characteristic of raw material, natural pond liquid or fresh water (FW) inject to regulate raw material to reach design and operation concentration by concentration adjustment mouth 103.
Regulate while concentration and open rabbling mechanism, shaft 201 drives helical blade 202 to rotate natural pond liquid and raw material to be mixed.Mixed process can effectively by the organic substance in raw material and husky separation.Because mixing speed is comparatively slow, husky meeting natural subsidence is to housing 1 intracavity bottom.
The sand of deposition is by mechanism 4 of removing sand from charging aperture 101 end band to discharging opening 102 end, and it is outside to drain into housing 1 by the mouth 403 that removes sand.Remove sand and control according to the difference of content husky in raw material running time of mechanism 4.
Equipment run duration, heating arrangements is opened, and is evenly passed to housing 1 inner from heat(ing) coil 301 by zone of heating 302.Meanwhile, this even heat is distributed in material by rabbling mechanism, makes heating material even, improves raw material acidifying level.Material, after housing 1 inner chamber stops 10H, is disposed in marsh-gas fermentation tank by discharging opening 102.
The occupation area of equipment that the utility model provides is little, and raw material mixes, and removes sand effective, and pretreatment degree is high, homogenize, removes sand, to heat and acidization is integrated in same device and carries out simultaneously, has saved the processing time, has improve production efficiency; Device is closed, is heated, reduces thermal losses, improve the thermal efficiency by heat-insulation layer and zone of heating from outside to device, contributes to promoting acidizing effect; The uniqueness designed by helical blade is related to, and guarantee can fully homogenize, can not affect again sandstone precipitation.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
