(3) double film gas holder caissons of the present utility model are antifreeze non-maintaining, do not have water in gas holder, so need not be independent
Antifreeze consideration.Gas holder is designed with ice storage layer, and the steam that can also be stored in the biogas of part when winter freezes.Control system
The anhydrous design of dry type, the environment relatively low available for temperature are also used with protection system.Using special low-temperature resistance material supply section be used for-
In 50 DEG C of environment.
(4) small investment simple in construction.It does not have the various metalworks such as guide rail, piston, balancing pole and outer barrel, makes and installs
Become extremely simple, gas holder uses industrialized production in factory, and efficiency high, cost are relatively low, and may be reused.Gas holder is to peace
Dress and fundamental importance be not high, and additional rates is with low.
(5) the double film gas storage holders of good appearance are generally 76% spherical, are stood erect among the tank body of cylinder, are complemented each other,
Appearance is more rich.There is preferable self-cleaning property using the PVDF membrane materials handled, can keep very long in natural environment
The original new color and luster and clean degree of time.
The utility model is described in more detail below by embodiment.
Brief description of the drawings
Fig. 1 is the structural representation of double film gas holder caissons of the present utility model.
Embodiment
The utility model is further described in a manner of embodiment combination accompanying drawing below.
As shown in figure 1, it illustrates the concrete structure of double film gas holder caissons of the present utility model, this pair of film gas holder storage
Device of air includes counterdie 2, inner membrance 3, outer membrane 1, pre-buried pressing plate 8, a switch boards 6, b switch boards 10, protector 9 and outer membrane
Water seal 7, wherein counterdie 2 and outer membrane 1 connect and surround a closed gas storage space jointly, and the inner membrance 3 is located in outer membrane 1 and by institute
State closed gas storage space and be divided into gas storage space 5 and pressure regulation space 4, the outer membrane 1, inner membrance 3, counterdie 2 are all fixed on described
On pre-buried pressing plate 8, the outer membrane water seal 7 is communicated to the pressure regulation space by a switch boards 6, and the b switch boards 10 control described
Protector 9 is communicated to the gas storage space 5 and pressure regulation space 4.
Switch board b has the correlation rangefinder for being used for measuring spacing between inner membrance and outer membrane top.When storage gas increases
The expansion of inner membrance 3 rises when more, and spacing is varied down to critical value between inner membrance and outer membrane top, and now b switch boards 10 control safe guarantor
Shield device 9 discharges pressure regulation air out of pressure regulation space 4 and vacates certain capacity, biogas is smoothly entered gas holder.Such as
Fruit inner membrance 3 rises to the limit, when there is situation about being pressurized, now protector 9 then can protectiveness release inner membrance 3 in gas
Body.Reach and do not allow inner membrance 3 to be pressurized, protect the purpose of inner membrance.
When the gas of storage in inner membrance 3 is reduced, inner membrance declines, then a switch boards then inject pressure regulation sky by outer membrane water seal 7
Gas, the pressure in balancing tank.The rigidity of Simultaneous Stabilization outer membrane 1, the gas of storage is set smoothly to flow out gas holder.
Also include exhaust apparatus 11, the exhaust apparatus 11 is arranged on pre-buried pressing plate 8.The exhaust apparatus 11 includes exhaust
Pipe, pressure regulator valve 13 and clarifier 12, the blast pipe are connected by pressure regulator valve 13 with the protector 9, the exhaust
The port of export of pipe is divided into three branch pipes, and one of branch pipe is provided with clarifier 12, passes through the clarifier 12 for extraneous air
Enter with after pressure regulator valve 13 and the protector 9 in the pressure regulation space 4.The profile of double film gas holder caissons
It is spherical for 3/4, and it is provided with watch window on the outer membrane 1.
By largely detecting and testing on the spot, the inner membrance of double film gas storage holders is once loaded with and will be pressurized, once it is pressurized
Just have the situation of seepage.(inner membrance compression refers to interior film pressure and subtracts outer film pressure) inner membrance needs good pliability, base used
Cloth is softer.It is poor with respect to outer membrane bearing capacity.Plus the permeability of membrane material in itself, once being pressurized to leak, it is pressurized and gets over gross leak
It is bigger.Inner membrance, which is once filled, will be pressurized and leak.
Inner membrance made allowance is given in the utility model active pressure release, does not fill and is not pressurized.Outside when usual gas holder inner membrance is discontented with
Film can offset the pressure of inner membrance, and inner membrance is hardly pressurized.Membrane protective system is using control appearance technology, 90% report in the utility model
It is alert, 98% discharge (PLC controls are adjustable), inner membrance is not filled.So not being pressurized, also just do not leak.Outer membrane is equipped with this reality
With new active relief valve, automatically turned on by PLC.Outer membrane pressure release state is set to be in grasp, can be according to time, gas holder shape
State, inner membrance height adjustment vent pressure.Active relief valve is safe and reliable, fault rate less than 1%, but appoint so have damage and
The risk of power failure.
The spare physical safety valve of meticulous development that the utility model is equipped with, with simple counterweight safety valve and spring safety
The same reliable of valve.Difference is that precision greatly improves, reachable ± 0.05KPa.And -40 DEG C available.
The beneficial effects of the utility model be cracked for current caisson, unstable characteristic, ensuring safety
Under conditions of practicality, biogas storage requirement is disclosure satisfy that, reduces cost as much as possible, realize that biogas stores safely.
Double film gas holder caissons of the present utility model are not limited to the structure of above-described embodiment, can carry out a variety of modifications.
In a word, both fallen within all improvement not departed from the utility model scope in the scope of the utility model.
