Abstract

A semi-underground solar anaerobic fermenter in a sun shed mainly includes a sun shed, a solar warming pipe, an anaerobic fermenter, an insulation layer, a heat delivery pipe, a warming heat exchanger, and a biogas delivery pipe. The anaerobic fermenter is constructed in the sun shed and is a semi-underground structure. The solar warming pipe is arranged in the sun shed. The solar warming pipe is communicated with the warming heat exchanger in the anaerobic fermenter through the heat delivery pipe. To achieve a constant temperature, heat insulation, gathering warm and warming composite structure, the solar warming pipe is arranged in the sun shed, and the anaerobic fermenter is constructed in the sun shed in a semi-underground manner. The conventional anaerobic fermenter is affected by cold climate factors in winter, so that the project cost is too high and the biogas is hard to generate at low fermentation temperature. Such problems are overcome.

Technical field

The utility model relates to a kind of biogas engineering, relates in particular to a kind of interior semi-underground type solar anaerobic fermentation tank of a kind of sunlight shed that is suitable for the operation of northern China cold district.

Background technology

The biogas engineering that present China builds mainly is to utilize boiler, sunlight shed, generator waste heat and solar heating pipe to come to heat to anaerobic fermentation tank.As everyone knows, the biogas engineering operation is produced the required leavening temperature of methane and is required at the 35-65 degree, north of china in winter severe cold low temperature particularly, the boiler temperature-increasing expense is too high, environmental protection policy also limits use, cause biogas engineering can't move production biogas, biogas generator stops generating, nothing left thermogenesis without biogas for combustion; The low solar heating pipe of north of china in winter temperature is freezing serious in addition, can't guarantee that anaerobic fermentation tank is needed to heat requirement; Therefore, research and development can at the anaerobic fermentation tank of northern area normal operation in winter, be the problems of being badly in need of solution.

The utility model content

The purpose of this utility model is to solve the prior art existing problems, semi-underground type solar anaerobic fermentation tank in a kind of sunlight shed is provided, to realize constant temperature, be incubated, adopt temperature, to heat textural association, overcome the in the winter time cold factor affecting of climate of existing anaerobic fermentation tank, caused the low difficult problem of not producing biogas of the high leavening temperature of engineering operation cost.

The purpose of this utility model realizes by the following technical solutions: semi-underground type solar anaerobic fermentation tank in a kind of sunlight shed, mainly comprise sunlight shed, solar heating pipe, anaerobic fermentation tank, thermal insulation layer, thermal source transfer lime, heat interchanger, biogas transfer lime, it is characterized in that: described anaerobic fermentation tank is built in the sunlight shed, the semi-underground type structure, the solar heating pipe is installed in the sunlight shed, and the solar heating pipe is connected and communicates by heating interchanger in thermal energy transfer duct and the anaerobic fermentation tank;

Semi-underground type solar anaerobic fermentation tank in above-mentioned a kind of sunlight shed, its sunlight shed is existing engineering feature, no longer does description at this;

Semi-underground type solar anaerobic fermentation tank in above-mentioned a kind of sunlight shed, its solar heating pipe is fixed on top in the sunlight shed with shape in a row by angle iron bracket;

Semi-underground type solar anaerobic fermentation tank in above-mentioned a kind of sunlight shed, its anaerobic fermentation tank is integrated semi-underground type, and two film gas storage holders are installed in the fermentor tank top, and tank body is steel design, and overground part sets up urethane and extrusion molding heat preservation of board separately; Underground part tank body peripheral hardware pearlite insulating layer and brick mix structure exterior enclosure wall;

The utility model compared with prior art has the following advantages:

(1) the utility model solar heating pipe is installed in the sunlight shed, and is isolated by sunlight board and cool ambient air, and it is freezing that the normal use of winter solar energy heating pipe can not crossed low reason because of temperature.

(2) the utility model solar heating pipe utilizes the sunlight shed high-transmittance to gather the sunlight thermal source, heats for anaerobic fermentation tank.

(3) the utility model anaerobic fermentation tank is built in semi-underground structure in the sunlight shed, and adopt by sunlight shed and leniently descend soil layer constant temperature, and the thermal insulation layer insulation, reduce heat energy loss, reduce operation and heat cost, reach high yield tolerance.

(4) the utility model anaerobic fermentation tank underground part is provided with pearlite insulating layer, and over-ground part is provided with the lagging materials such as urethane, extrusion molding sheet material, has guaranteed that thermal source heats effect lastingly in fermentor tank.

Embodiment

Now by reference to the accompanying drawings and embodiment, the utility model is further described as follows:

From Fig. 1 and Fig. 2 as seen, semi-underground type solar anaerobic fermentation tank in a kind of sunlight shed of the utility model, mainly contain sunlight shed (1), solar heating pipe (2), anaerobic fermentation tank (3), thermal insulation layer (4), thermal source transfer lime (5), heat interchanger (6), biogas transfer lime (7) forms, more than be the total constructed feature of the utility model and existing methane engineering technology, therefore be not described further.

Planner of the present utility model has carried out effective technological improvement to existing biogas engineering construction, makes it to be more suitable for the northern China severe cold area.This improvement can be from Fig. 1 and Fig. 3: biogas project anaerobic fermentation tank (3) builds up the semi-underground type structure, the above part in ground is strengthened insulation with materials such as urethane, extrusion molding sheet materials, anaerobically fermenting tank body (3) underground part sets up perlite insulation separately, the constant temperature characteristics of underground soil layer have been utilized again, the interior heat of fermentation of anaerobic fermentation tank (3) is reduced to run off, the engineering department is moved under the optimum temps state, kept high yield tolerance; The wide canopy in top Jianyang (1), sunlight shed (1) are by the protection feature of good light transmission high-quality, and the sunlight thermal source of collection has increased the temperature in the whole process area, and isolated process area contacts with cool ambient air again simultaneously; The booth internal upper part is installed solar heating pipe (2), solar heating pipe (2) links to each other by heating interchanger (6) in thermal source transport pipe (5) and the fermentor tank (3), solar heating pipe (2) utilizes the light transmission of sunlight shed (1), collecting the sunlight light energy conversion is heat energy, utilize transfer lime (5) road to transmit in the heat energy arrival anaerobic fermentation tank (3) and heat interchanger (6) heat exchange, make the interior fermentation raw material leavening temperature of anaerobic fermentation tank (3) reach the temperature of the technological design that needs; Therefore, the utility model has possessed simultaneously constant temperature, has been incubated, has adopted temperature, has heated function, has guaranteed can normally move after the northern frore area biogas engineering builds up, and has reduced running cost.By above description, be not difficult to find the utility model not only at the northern frore area biogas engineering, result of use is better in southern biogas engineering is built.
