Description
Technical field
The utility model relates to positive negative pressure protector, and is particularly a kind of for the positive negative pressure protector of regulating marsh-gas fermentation tank or two film Holder System pressure.
Background technology
Marsh-gas fermentation tank and two film gas holder are in the course of the work, can cause marsh-gas fermentation tank or two film gas storage holder internal pressure to raise owing to terminating unit is out of service, too high operating pressure can form the safe operation of equipment and threaten, and at this moment just needs too high pressure is laid down the safety of moving with assurance equipment; Equally, when the biogas air feed is not enough, lasting also can the causing in marsh-gas fermentation tank or the two film gas storage holder with gas of biogas terminating unit forms negative pressure, safe operation to equipment forms threat equally, barometric point can be marsh-gas fermentation tank or the crimp of two film gas storage holder when serious, cause the equipment profile to change and then cause biogas to leak, meet the naked light accident of blasting.Marsh-gas fermentation tank and two film gas holder are badly in need of the threat that a kind of positive negative pressure protector protection equipment is avoided ultra-high voltage and super negative pressure, guarantee to be provided with safe operation.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of system pressure that can regulate marsh-gas fermentation tank or two film gas storage holders, makes the positive negative pressure protector of its normal operation.
For solving the problems of the technologies described above, the utility model comprises that the bottom is provided with the pressure regulating tank of supporting leg, and pressure regulating tank inside is provided with dividing plate, and dividing plate is divided into upper chamber and lower chambers with pressure regulating tank inner chamber, and bottom chamber is equipped with liquid; Be connected with on the pressure regulating tank that an end stretches out the pressure regulating tank, the other end passes the pipe connecting that dividing plate stretches into lower chambers; Described dividing plate is provided with the submerge vapor pipe of bottom chamber liquid of its bottom, and the vapor pipe upper end connects with upper chamber, and the pressure regulating tank is provided with the relief tube that is communicated with upper chamber, and the top of relief tube is equipped with the last liquid-blocking cap with its top formation exhaust clearance; Described pressure regulating tank top is provided with spout, and pressure regulating tank bottom is provided with sewage draining exit.
After adopting said structure, pipe connecting is communicated with marsh-gas fermentation tank or two film gas storage holder, and inject liquid in bottom chamber and make the submerge pressure of the degree of depth of liquid and marsh-gas fermentation tank or two film gas storage holders of vapor pipe suitable, when the pressure of marsh-gas fermentation tank or two film gas storage holders surpasses prescribed value, high pressure gas are rushed in the pressure regulating tank and are broken through liquid resistance and enter upper chamber by vapor pipe and discharge from relief tube, thereby make the pressure in marsh-gas fermentation tank or the two film gas storage holder be down to prescribed value; When marsh-gas fermentation tank or two film gas storage holder pressure were lower than certain value, system can fall negative-pressure balancing by the vapor pipe suck air, and inhaled air is disposed to the safe mixed gas limit when equipment starts again, guaranteed the equipment operating safety.The utility model can well be regulated the system pressure of marsh-gas fermentation tank or two film gas storage holders, and pressure is normal when guaranteeing its operation, thereby makes its safe operation.
Described liquid-blocking cap one side that goes up is hinged on the relief tube, and opposite side is provided with the fixture block that just in time is stuck on the relief tube tube wall.
Described pipe connecting is provided with the tensimeter installing port.
The top of described vapor pipe is connected with down liquid-blocking cap.
Described pressure regulating tank is provided with the pressure warning unit that is communicated with lower chambers.
Described relief tube is connected by the mouth of pipe of flange with pressure regulating tank top.
Described pressure regulating tank is provided with liquidometer.
