The device comprises the double-membrane gasholder consisting of an inner membrane and an outer membrane, wherein a gas outlet valve for controlling the on-off of a pipeline is arranged on a gas outlet pipeline of the double-membrane gasholder; a voltage stabilization cavity is formed between the inner membrane and the outer membrane, and is communicated with an air blower through a pressure-equalizing pipe; a control valve, a safety valve, a pressure gauge and a methane leakage probe which are used for controlling the on-off of the pipeline are sequentially arranged on a pipe section between the air blower and the voltage stabilization cavity; the air blower, the pressure gauge, the methane leakage probe, the control valve and the gas outlet valve are electrically connected with a controller; and the controller is used for controlling the on-off of the air blower, the control valve and the gas outlet valve. When various emergency conditions occur, the device is controlled in an interlocking mode, so that effective measures can be taken in time, accidents can be prevented from being enlarged, and safe operation of equipment can be ensured.
Description
Technical field
The utility model relates to a kind of pair of film gas holder safety protection device.
Background technique
Two film gas holders are the special devices that store biogas in present biogas engineering and the sewage treatment project.Because the material of at present two film gas holders is a flexible film material; Pliability is fine but rigidity not enough; In case suffer that improper external force is hit or the flexible membrane material arrives and causes breakage working life; Cause biogas to leak, inflammable gas is met naked light and is blasted in explosion limit, the entail dangers to person and equipment operation safety.Do not have suitable safety protection device to solve biogas at present and leak the danger that brings, avoid having an accident.
Summary of the invention
The technical problem that the utility model will solve provides a kind of two film gas holder safety protection devices that can guarantee two film gas holder safe operations.
For solving the problems of the technologies described above; The utility model comprises two film gas holders of being made up of inner membrance and adventitia; The outlet pipe of two film gas holders is provided with the gas outlet valve of controlling plumbing fixtures break-make; Its structural feature is to form the voltage stabilizing cavity volume between said inner membrance and the adventitia, and the voltage stabilizing cavity volume is communicated with blower through pressure-equalizing pipe, and the control valve, safety valve, pressure gauge and the biogas that are provided with the pilot line break-make on the pipeline section between blower and the voltage stabilizing cavity volume successively leak probe; Said blower, pressure gauge, biogas leak probe, control valve and gas outlet valve and all are electrically connected with controller, the switch of controller control blower, control valve and gas outlet valve.
After adopting said structure; Under the normal working, blower is inflated to gas holder and is 3/4ths spheroid forms in the voltage stabilizing cavity volume, when the pressure of voltage stabilizing cavity volume reaches specified value; Pressure gauge outputs signal to controller; Controller is controlled blower automatically and is quit work, and when pressure was lower than specified value, blower started automatically.When because the inner membrance biogas pressure increases, when causing the air pressure of gas holder voltage stabilizing cavity volume to surpass specified value, safety valve is opened pressure release automatically to specified value; Under abnormal operating state, because unexpected factor or film material fatigue cause inner membrance crackle to occur, when leaking appears in biogas; The air pressure of voltage stabilizing cavity volume can sharply raise, and safety valve is opened pressure release automatically, when this moment, the biogas leakage rate surpassed certain value; Biogas leaks probe can in time be sent to controller with leaking electrical signal; Controller is reported to the police and simultaneously blower, gas outlet valve, control valve is closed, thereby cuts off source of the gas, prevents the accident extension.The safety protection device of this kind interlocked control can effectively guarantee equipment safety operation.
Said controller is the PLC controller.
Said pressure gauge is a capsule pressure gauge, measures precisely.
The normal pressure of said voltage stabilizing cavity volume is 800～1000Pa, guarantees the safety of inner membrance and adventitia.
Said biogas leakage rate alarming value is 25LEL, warning in advance, and the accident that prevents takes place.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; Two film gas holder safety protection devices comprise two film gas holders 3 of being made up of inner membrance 1 and adventitia 2; The outlet pipe 5 of two film gas holders 3 is provided with the gas outlet valve 6 of controlling plumbing fixtures break-make; Form voltage stabilizing cavity volume 4 between inner membrance 1 and the adventitia 2; Voltage stabilizing cavity volume 4 is communicated with blower 8 through pressure-equalizing pipe 7; The control valve 12, safety valve 9, pressure gauge 10 and the biogas that are provided with the pilot line break-make on the pipeline section between blower 8 and the voltage stabilizing cavity volume 4 successively leak probe 11, and blower 8, pressure gauge 10, biogas leak probe 11, control valve 12 and gas outlet valve 6 and all is electrically connected with the PLC controller, the switch of the control of PLC controller blower 8, control valve 12 and gas outlet valve 6.Pressure gauge 10 is a capsule pressure gauge, and gas outlet valve 6 is solenoid valve with control valve 12.The normal pressure of voltage stabilizing cavity volume 4 is 800～1000Pa, guarantees the safety of inner membrance and adventitia.Biogas leakage rate alarming value is 25LEL, warning in advance, and the accident that prevents takes place.
Under the normal working; Be inflated to 3/4ths spheroid forms of regulation in the voltage stabilizing cavity volume 4 that blower 8 forms between two film gas holder inner membrances 1 and adventitia 2; When the pressure of voltage stabilizing cavity volume 4 reached 1000Pa, pressure gauge 10 outputed signal to controller, and controller is controlled blower 8 automatically and quit work.When pressure was lower than 800Pa, blower 8 started automatically.When because inner membrance 1 biogas pressure increases, when causing the air pressure of gas holder voltage stabilizing cavity volume 4 to surpass 1000Pa, safety valve 9 is opened pressure release automatically to 1000Pa; Under abnormal operating state, because unexpected factor or film material fatigue cause inner membrance 1 crackle to occur, when leaking appears in biogas; The air pressure of voltage stabilizing cavity volume 4 can sharply raise, and safety valve 9 is opened pressure release automatically, when this moment, the biogas leakage rate surpassed 25LEL; Biogas leakage probe 11 can in time will leak electrical signal and be sent to controller; Controller is reported to the police and simultaneously blower 8, gas outlet valve 6, control valve 12 is closed, thereby cuts off source of the gas, prevents the accident extension.The safety protection device of this kind interlocked control can effectively guarantee equipment safety operation.
