Description
Technical field
The utility model belongs to agricultural technology field, relates to a kind of methane-generating pit.
Background technology
In recent years, construction methane generating pit had become a kind of demand of the our province vast farmers masses.The peasant when using biogas, the mistaken ideas that ubiquity " thinks that the pressure of biogas is the bigger the better ".They think that the pressure of biogas is more big, and the firepower of methane cooker is just more prosperous, and the speed of heating up water of cooking is just fast; The pressure of biogas is more big, and aerogenesis is more many, and it is more good to build pond skilled worker's technology.Yet the fact but is not such.The size of biogas pressure, only relevant with the relative size of structure, peasant's gas consumption and the methane tank gas production amount of methane-generating pit.Biogas pressure is too big, and only harmful do not have a benefit, is summarized as follows:
The harm that biogas pressure is excessive: 1, biogas pressure is excessive, and directly threatening the safe GB family of methane-generating pit vault construction is 8kpa with the operating pressure that hydraulic type biomass pool designs, and maximum working pressure is 12kpa.If pressure is excessive, the methane-generating pit vault just might appear by the situation of biogas spalling.In the reality, also often run into because of methane-generating pit vault timely earthing various places, and it is excessive and cause the methane-generating pit of the example, particularly brick mix structure of vault cracking to add air pressure.2, biogas pressure is excessive, is to cause the major cause methane-generating pit skylight opening removable cover of methane-generating pit skylight opening removable cover gas leakage to seal with clay.The viscous force of clay itself is limited, and when pressure exceeds certain scope, clay will be extruded by the biogas of excess pressure, causes the phenomenon of gas leakage.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, proposed a kind of biogas pressure in the body of pond can automatic deflation when excessive to the methane-generating pit of depositing in the gas tank, this methane-generating pit has longer service life, uses safer characteristics.
The purpose of this utility model can realize by following technical proposal: a kind of methane-generating pit, comprise pond body and Chi Gai, it is characterized in that, this methane-generating pit also comprises deposits gas tank and pipe connecting, described pipe connecting one end is connected with described pond body, the described pipe connecting the other end is connected with the described gas tank of depositing, be provided with magnetic valve in the described pipe connecting, be provided with pressure transmitter and PLC programmable logic controller in the body of described pond, described pressure transmitter links to each other with the PLC programmable logic controller with circuit two by circuit one respectively with magnetic valve.
Chi Gai covers at Chi Tishang, is coated in gap location between Chi Gai and the pond body by clay, makes both keep sealing.A force value is set in the PLC programmable logic controller, such as 12kpa, when the biogas pressure in pressure transmitter is sensed the pond body surpasses 12kpa, pressure transmitter passes to the PLC programmable logic controller with information, the PLC programmable logic controller is controlled magnetic valve again, make magnetic valve be in opened condition, the biogas in the body of pond enters into by pipe connecting deposits gas tank, and the biogas pressure in the body of pond reduces gradually; Clay just can not extruded by the biogas of excess pressure like this, and causes the phenomenon of gas leakage, and simultaneously, the PLC programmable logic controller is controlled magnetic valve again, makes magnetic valve be in closing condition, and the biogas in the body of pond no longer enters into deposits gas tank.
In above-mentioned methane-generating pit, described pressure transmitter links to each other with a display screen that force value can be shown, and described display screen is arranged on the pond and covers.
In above-mentioned methane-generating pit, also be communicated with a standby pipes on the body of described pond, the other end of standby pipes is connected with the above-mentioned gas tank of depositing, and described standby pipes is provided with valve.
In above-mentioned methane-generating pit, described pipe connecting adopts stainless material to make.
In above-mentioned methane-generating pit, described depositing offers the inlet mouth with internal thread on the gas tank, and described pipe connecting is threaded on the described inlet mouth.
In above-mentioned methane-generating pit, described pressure transmitter by screw retention on the inwall of pond body.
Compared with prior art, the utility model is by pressure transmitter, PLC programmable logic controller and magnetic valve, automatically realize the force value of biogas in the equalizing tank body, improve longer service life and the safety in utilization of methane-generating pit, simultaneously, too much biogas can be discharged into to deposit in the gas tank and deposit, and reduces the waste of biogas.
