Abstract

The invention discloses a biogas storage and circulation device for a small biogas tank, which is characterized in that a biogas outlet pipe at the upper end of the biogas tank is provided with an unidirectional biogas outlet valve, a safety exhaust valve, a water collector, a biogas storage bag and a tee, one port of the tee is connected with a stove, the other port of the tee is connected with a circulating pump, and an outlet of the circulating pump is connected to the bottom of the biogas tank. The device has the advantages that when the large gas pressure exists in the tank, the biogas storage bag stores excessive liquid, the excessive liquid can not backfill towards the inside of the tank under the action of the unidirectional valve and can only be discharged from the safety exhaust in a small quantity when certain pressure is exceeded, and biogas in the biogas storage bag enters from the bottom of the tank through the circulating pump, thereby realizing the automatic stirring of the biogas, preventing raw materials from crusting, and forming the continuous good circulation of the biogas.

Description

The methane storage and circulation device that is used for small-sized methane tank
Technical field
The application relates to a kind of biogas jar use device, relates in particular to 10m 3Following little biogas jar.
Background technology
At present, tradition biogas jar exists following deficiency, often causes feed liquid to flow out under high-pressure gas pressure outside the pond when biogas is sufficient, and exhaust in time could solve, the untimely bad methane-generating pit that rises easily of exhaust, expellant gas is again the obnoxious flavour that influences atmospheric environment.In addition, fouling easily in the existing biogas jar.
Summary of the invention
The application's purpose is to overcome the weak point that existing small-sized methane tank exists, and a kind of biogas circulation device simple in structure is provided.
In order to achieve the above object, the technical scheme that the application adopts is: unidirectional air outlet valve, safety exhaust, water collector, air storage bag and threeway are installed on the escape pipe of biogas jar upper end, a mouth of threeway connects cooking stove, another of threeway mouthful connection recycle pump, circulating-pump outlet is connected to the biogas pot bottom.
The application's advantage is:
When the jar internal gas pressure is big, store unnecessary liquid by air bag, counter filling in jar more not under the effect of check valve, just discharge on a small quantity during greater than certain pressure from safety exhaust, by recycle pump airbag gas is entered at the bottom of jar, realize that gas stirs automatically, prevent the raw material crust, form the good circulation that biogas goes round and begins again.
Description of drawings
Legend is the application's structural representation.
Among the figure: 1-biogas jar, the unidirectional air outlet valve of 2-, 3-safety exhaust, 4-water collector, 5-air storage bag, 6-threeway, 7-cooking stove, 8-recycle pump.
Embodiment
Below in conjunction with accompanying drawing general introduction is in detail done further in the application's enforcement.
As shown in Figure 1, the application installs unidirectional air outlet valve 2 on the escape pipe of biogas jar 1 upper end, unidirectional air outlet valve 2 connects safety exhaust 3, leads to air storage bag 5 by water collector 4, utilize threeway 6 to be communicated with cooking stove 7 again, another outlet of threeway 6 is recycled to again in the biogas jar 1 by recycle pump 8 gases.
The application installs water collector 4 at the pipeline lowest part, when cooking stove burnt, biogas was for cooking stove, when not burning, biogas is recycled to again in the biogas jar, can impel feed liquid to flow, prevent crust, feed liquid is evenly distributed, the enhancing microorganism contacts with raw material, make its increased activity, improve gas production rate, improve the efficiency of conversion of utilization ratio of raw materials and energy.This firedamp gas equipment on average improves gas production rate more than 20%, effectively utilizes biogas to improve more than 10%.
