Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of pair of film gas holder described in the utility model.
Embodiment
By reference to the accompanying drawings the utility model is described further, the manufacturing technology of this device is perfectly clear concerning this professional people
As shown in Figure 1, a kind of two film gas holder, this gas holder comprises adventitia 2, inner membrance 1, counterdie 3, retaining ring 4, level meter 8, air compensation device 6, pedestal 14 and biogas suction tude 7, retaining ring 4 is positioned on pedestal 14, air compensation device 6 is positioned on adventitia 2 and with air and communicates, level meter 8 is positioned on adventitia 2, and this pair of film gas holder also comprises air-out apparatus 5, and air-out apparatus 5 is positioned on adventitia 2.
Preferred version of the present utility model is that air-out apparatus 5 comprises pressure regulator valve 12, exhaust duct 13 and air outlet, exhaust duct 13 one end connect pressure regulator valve 5, the other end is arranged on the air outlet of adventitia 2 and exhaust duct 13 extends to from air outlet in the middle of adventitia 2 and inner membrance 1, the main purpose of pressure regulator valve 12 is the air-flows that adjust device of air, when blower 10 is during to adventitia 2 interior air blast, along with the increase of adventitia 2 inner air pressures, regulate adventitia 2 external and internal pressures by air-out apparatus 5, thereby reach the stability of the variation of regulating system internal pressure, and then the normal operation of the interior equipment of safeguards system, in the time of the benefit wind speed degree frequency shift of air compensation device, can, by regulating pressure regulator valve 12 control the pressure in adventitia 2, system equipment normally be moved, and can be applicable to different air blast frequencies, intrasystem stability is further provided, by cross-ventilation, the steam in film and condensed moisture are taken away, avoid the probe of top level meter 8 to adhere to steam or condensed water, ensure the accuracy that level meter 8 is measured.
This air-out apparatus 5 is preferably positioned at the medium position on adventitia 2, like this when air compensation device 6 is during to the interior air blowing of adventitia 2, air can flow to the interior all directions of adventitia 2, and air-out apparatus 5 is arranged on the medium position on adventitia 2, pressure regulator valve 12 was diffused into medium position according to adventitia 2 internal pressures and came sooner effectively to regulate this time, when Air Flow can better ensure the stability of equipment in system during to adventitia 2 interior every nook and cranny, because the size of gas holder is indefinite, can set out according to gas holder capacity the number of device of air 5, can be multiple.
The blower 10 of this air compensation device 6 can be also the device that can inflate, between adventitia 2 and inner membrance 1, provide constant storage pressure by air compensation device 6, air compensation device 6 is mainly to supplement air according to the size of adventitia 2 internal pressures, the stability of equipment in protective system, also can avoid adventitia 2 inter-adhesive with inner membrance 1 together with phase mutual friction and cause interior adventitia damage; Air compensation device 6 has also increased safety check 11, and when in the time that air compensation device 6 is mended wind speed degree slowly or turned off the blast, film internal pressure is greater than atmospheric pressure, safety check can ensure in film that air can not be back in atmosphere and causes equipment damage in system.
Level meter 8 is preferably arranged on the tip position of two film gas holders, and all situations and maintenance in tip position gets final product gamut measurement adventitia 2 provide perfect data.
Biogas suction tude 7 also can be provided with full valve, by biogas pipe, biogas is stored in gas holder, because the generation of biogas is persistency, and the speed producing differs, the speed of being carried out balance biogas and being entered gas holder by Safety valve, carrys out relief holder internal pressure, ensures the stability of gas holder.
