Description

Horizontal baffled alcohol fermentation tank
Technical field
The invention belongs to the field of engineering technology of continuously fermenting of Alcohol Production, relate to a kind of anaerobic fermentation tank specifically.
Background technology
Existing ethanol fermentation tank, usually all be vertical tank, development along with technology of alcohol, in the technology of continuously fermenting, in the particularly large-scale continuous fermentation process, use placed in-line a plurality of fermentor tank, each fermentor tank needs the fermentor tank with its upstream and downstream that links to each other respectively communicating pipe, every needs two valves communicating pipe at least and does technology control and use, and facility investment is bigger, and the pipeline dead angle is more; And because tank body has been realized maximization, material in each fermentor tank occurs remaining in a standstill and the phenomenon of slip-stream easily, thereby influenced the efficient of fermentation, for head it off, 2～3 side agitators are installed for often in the existing technology each fermentor tank, increase the facility investment of stirrer so again and increase power consumption,, increased by the chance of contaminating impurity simultaneously because of having set up perforate on the fermentor tank.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome effectively in the fermentor tank that material remains in a standstill and slip-stream shortcoming, minimizing pipeline dead angle, have the horizontal baffled alcohol fermentation tank that higher fermentation efficiency and facility investment more economize.
Technical scheme of the present invention is: horizontal baffled alcohol fermentation tank, the vertical radical length of tank body is less than horizontal axis length, its axial two ends are respectively equipped with material inlet and material outlet, radially vertically being provided with at least one in the tank body can will be divided into the dividing plate at least two intervals in the tank body, on dividing plate top or the bottom be provided with and be communicated with dividing plate both sides breach at interval.
As a kind of prioritization scheme, at least two of radially vertical settings can will be divided into the dividing plate at least three intervals in the described tank body in the tank body, and the breach on two adjacent dividing plates is staggered up and down to be oppositely arranged, and each communicates by breach about each at interval successively in the tank body.
Jar in polylith radially dividing plate horizontal fermentor tank be separated into several sweathouses every, each volume size at interval promptly is equivalent to a fermentor tank volume of prior art, can regulate the flow velocity of material at interval by the spacing of regulating between the dividing plate, thereby improve slip-stream and viscous flow phenomenon; By replaced connecting pipe and the valve between jar of the prior art and the jar at the breach of offering on the dividing plate, investment has been saved at the dead angle of having reduced pipeline.
The bottom that is provided with the described dividing plate of upper notch also is provided with the opening that prevents that bottom, interval material from accumulating, as preventing that material from forming precipitation material in each bottom, interval and accumulating the dead angle.When slack tank, whole emptying materials; During cleaning, then can not produce buildup, ponding.
Along the Flow of Goods and Materials direction, each the breach area that is located at described dividing plate top increases successively, can guarantee that like this material has the overflow backward of enough potential differences, makes karusen can be smoothly flow at interval next at interval from of front.
Spacing between each described dividing plate can be identical, also can be inequality.Root a tree name process characteristic is provided with the spacing distance between the dividing plate, favourable to eliminating slip-stream with viscous flow, simultaneously can also adapt to the demand of different operation stages to fermenting space, for example, main fermentation stage, the vigorous precipitation that is not easy owing to fermentation, it at interval can be more greatly, and is along with weakening of fermentation, more little as interval more backward, the flow velocity of karusen in jar increased, improve or overcome remaining in a standstill and the slip-stream phenomenon.
Between described dividing plate periphery and the described inner tank wall is to be welded to connect, and adjacent like this sweathouse can not be short-circuited every interior material.
Be provided with axial spacing muscle between the adjacent described dividing plate, such dividing plate periphery directly is not connected with tank body, but pass through machine design method, make dividing plate be suspended in the jar in vertical state, the bottom has moving fulcrum to support, determine to make removable spacing with the spacing muscle after the distance, so just can save a large amount of welding job amounts.
Described dividing plate is provided with stiffening web, can guarantee the rigidity of dividing plate, prevents distortion under the washing away of material.
Be provided with the outlet pipe and the inlet pipe that are communicated with forced cooling and circulating system outside the jar on the tank body behind the described dividing plate of each ingress, described interval, wherein outlet pipe be located at the angle of the described dividing plate back lower place and its axial line and horizontal plane be 45 the degree, inlet pipe is located at respectively that top is provided with the back upper place of described dividing plate of breach and the angle of its axial line and horizontal plane is 45 degree, and to be located at angle that the bottom is provided with the back lower place of described dividing plate of breach and its axial line and outlet pipe axial line be 90 to spend.Outlet pipe is located at the below, guarantees that external coolant circulation pump is difficult for finding time, and the kinetic head that can make full use of recycle stock that is provided with of inlet pipe stirs being easy to sedimentary position in the jar.
The vertical cross-section of described tank body is shaped as circle, U-shaped or trilateral, to adapt to different production technique and tank body volumetrical needs.
Advantage of the present invention is:
1, efficiently solves slip-stream, the viscous flow shortcoming of the jar that continuously ferments, improve fermentation efficiency;
2, cancel top upflow tube, following communicating pipe and pipe fitting, valve member, reduced the pipeline dead angle;
3, can save the facility investment 25～30% of fermentation procedure;
4, can save the civil engineering floor space 25～30% of fermentation procedure, save construction investment 25～30%.
