Abstract
The invention relates to a method for insulating an anaerobic fermentation tank by using a solar pond. The salt solar pond is directly used for insulating an anaerobic fermentation tank body, and heat in the solar pond is not extracted and used. Key units required in the method comprise a salt gradient solar pond, an anaerobic reactor, a transfer pump, a gas storage bin and a tank body support. Efficient insulation of the fermentation tank in the solar pond is realized, and costs of thermal insulation materials of a methane pot are saved. Compared with the traditional solar pond heat extracting mode, the method has the advantages that electric energy used for a heat extraction medium flowing water pump is saved, flowing of a lower convection layer in the solar pond is reduced, convection heat transfer between the lower convection layer and a non-convection layer is reduced, and insulation capability of the solar pond is improved. The method is suitable for insulating the anaerobic fermentation tank. In addition, complex pipe laying is not required in the method, and costs of gas yielding and insulating are greatly reduced.
Description
Technical field
The present invention relates to a kind of concrete grammar utilizing solar pond to carry out the anaerobic reactor be incubated, belong to biogas production and utilize technical field.
Background technology
The anaerobic reactor major part come into operation at present is not incubated, causing cannot normal fermentation, nowadays the heating means come into operation have solar water heating, electrically heated, boiler heating etc., although heat insulation effect is obvious, but for the biogas production that return is lower, invest relatively large.The artificial brine tank of salt gradient solar pond to be a kind of with solar radiation the be energy, its utilizes the Chi Shui with certain salt concentration gradient as heat collector, and its tradition carries hot mode two kinds, and the first puts heat exchanger at pond base fabric, utilizes heat-transfer working medium to flow out heat exchange; The second is hot water from the extraction pond, one end of lower convective region, and hot water returns at the bottom of pond after entering pond external heat exchanger heat exchange.The essence of these two kinds of methods is all drawn by heat to carry out heat exchange, promotes difficulty relatively large for insulation anaerobic reactor, applies research that the good salt gradient solar pond of heat accumulation is anaerobic reactor insulation or less so far.
Summary of the invention
For solving an above existing difficult problem, the invention discloses a kind of method utilizing solar pond to carry out being incubated anaerobic reactor.This method directly anaerobic reactor is placed in solar pond, and the heat utilizing solar pond to absorb is incubated anaerobic reactor, and can realize the function of anaerobic reactor automatic tracing fermentation optimum temperuture.
Invention comprises a kind of solar pond that utilizes and carries out the anaerobically fermenting tank arrangement be incubated, comprise opening for feed, anaerobic fermentation tank, escape pipe, discharge nozzle, mateiral pump, gas storage storehouse and tank support, described device also comprises salt gradient solar pond, described anaerobic fermentation tank is provided with sensor, described tank support is vertically connected to anti-rot plastic bar, described anti-rot plastic bar is provided with Controlling System, and described sensor is connected by electric wire with Controlling System.
A nearly step, one end of described anaerobic fermentation tank, escape pipe, discharge nozzle, tank support and opening for feed and anaerobic fermentation tank junction is positioned at salt gradient solar pond.
A nearly step, described Controlling System comprises temperature sensor, 51 micro-chips, stepper motor driver and two-phase six line stepper-motor.
A nearly step, described anaerobic fermentation tank is capsule shape, and itself and escape pipe all use PE plastic hose.
Beneficial effect: present invention achieves the high-efficiency insulated of anaerobic reactor in solar pond, save the expense of tank for sewage gas lagging material, compared with carrying hot mode with traditional solar pond, have to save and carry hot working fluid flowing water pump electric energy used, reduce lower tropospheric flowing in solar pond, reduce the convective heat exchange of lower troposphere and non-convection layer, strengthen the advantage of the insulated capacity of solar pond, in addition, this heat preserving method does not need complicated pipe installation, and aerogenesis and insulation cost are reduced greatly.
