Abstract

The utility model discloses a material liquid automatic circulation device of a marsh gas pool, which is equipped with a fermentation tank (4), a sealing tank cap (2), a feeding and discharging pipe (1), and a gas outlet pipe (3). The utility model is characterized in that a liquid supplementing box (5) is also arranged, an overflow pipe (6) is arranged inside the liquid supplementing box, a filtering cover (6.1) is arranged at the upper pipe opening of the overflow pipe, a float (6.2) is arranged in the pipe, and a lower pipe opening is communicated with the inside of the fermentation tank; a water return pipe (7) is also arranged at the bottom part of the liquid supplementing box, a water return valve (7.1) is arranged at the upper pipe opening of the water return pipe, the valve is connected with the float through a pulling line (6.3), the lower opening of the water return pipe is communicated with a U-shaped pipe (9) in the fermentation tank and a slag flushing pipe (8) of a lower pipe opening extending into the bottom part of the fermentation tank through a three-way valve (7.2), the U-shaped pipe is a soft pipe body, and a float (9.1) is installed at the upper opening.. The utility model is suitable for the production of marsh gas, and has the characteristics that the production of the producing marsh is continuous, the efficiency is high, and the maintenance is simple and the operation is secure.

Description

Methane-generating pit feed liquid automatic circulation device

Technical field

The utility model belongs to a kind of methane-generating pit, and concrete is that a kind of feed liquid that is provided with is overflowed automatically, again the methane-generating pit of the circulation device that can replenish automatically.

Background technology

Biogas technology is very fast in China's development, and a large amount of biogas technologies and product arise at the historic moment.Many good technology and products are wherein arranged, produced huge economic benefit and social benefit.But, wherein can better solve methane-generating pit or jar in pressure excessive, can release the pressure automatically, and the technology of the crust on feed liquid surface in the pond and pond base plate knot of effectively solving is also few.Therefore, need to propose the further improved methane-generating pit technology of structure and solve the problems referred to above.

The utility model content

The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of methane-generating pit feed liquid automatic circulation device.This device can be regulated the pressure in the biogas jar automatically, and can overcome the problem that crusting in the feed liquid surface and hardens in the bottom in the jar.

The purpose of this utility model is achieved through the following technical solutions: methane-generating pit feed liquid automatic circulation device, be provided with fermentor tank, sealed tank cap, feed and exhaust tube, escape pipe, it is characterized in that: also be provided with a fluid infusion case, be provided with an overflow pipe in this fluid infusion case, the upper orifice of this overflow pipe is provided with a filter mantle, be provided with a float in the pipe, lower nozzle is communicated with fermentor tank is interior; Also be provided with a return water pipe in fluid infusion case bottom, the upper orifice of this return water pipe is provided with a backwater valve, this valve is connected by a backguy with described float, the end opening of return water pipe is communicated with by the flushing cinder pipe that U-shaped pipe in a three-way valve and the fermentor tank and lower nozzle stretch into the fermentor tank bottom, described U-shaped pipe is soft body, it is suitable for reading be equipped with one cursory.

The utility model is owing to be provided with overflow pipe, and when pressure was excessive in the biogas jar, feed liquid was pressed into the filter mantle inflow water supply tank of overflow pipe by the mouth of pipe, and pressure reduces in the jar thereby make; When biogas is discharged from a jar internal pressure when reducing, because the height setting of overflow pipe, feed liquid in the water supply tank and water can not reflux, so produce pressure reduction between water supply tank and biogas jar; Feed liquid is depleted to a certain degree in jar, it is same when the last plane of feed liquid drops to a certain degree in jar, described float is followed decline, and by backguy with the backwater valve pull-up, feed liquid and water in the water supply tank are entered in the jar from pot bottom and feed liquid surface by return water pipe, three-way valve and flushing cinder pipe and U-shaped pipe, like this, give a jar interior fluid infusion moisturizing on the one hand, because have certain pressure, the crust and the hardening of jar end on feed liquid surface can be softened elimination again.The utlity model has novel and reasonable structure and be suitable for, easy maintenance can prevent that overvoltage is caused danger in the biogas jar, again can automatic water supplement, and eliminate crust automatically and harden the advantage that gas producing efficiency is high.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described: embodiment: methane-generating pit feed liquid automatic circulation device, be provided with fermentor tank 4, sealed tank cap 2, feed and exhaust tube 1, escape pipe 3, it is characterized in that: also be provided with a fluid infusion case 5, be provided with an overflow pipe 6 in this fluid infusion case, the upper orifice of this overflow pipe is provided with a filter mantle 6.1, be provided with a float 6.2 in the pipe, lower nozzle is communicated with fermentor tank is interior; Also be provided with a return water pipe 7 in fluid infusion case bottom, the upper orifice of this return water pipe is provided with a backwater valve 7.1, this valve is connected by a backguy 6.3 with described float, the end opening of return water pipe is communicated with by the flushing cinder pipe 8 that U-shaped pipe 9 in a three-way valve 7.2 and the fermentor tank and lower nozzle stretch into the fermentor tank bottom, described U-shaped pipe is soft body, and it is suitable for reading to be equipped with one cursory 9.1.

Present embodiment is through practical probation, and effect is very good, and is easy to use, safety, and aerogenesis is continuous, easy maintenance.
