The utility model is related to a kind of dry gas-holder intelligent controlling device, is mainly used in the pressure that dry-type methane stores gas holder
Control.
Background technology
With the rapid growth of global economy, the energy and environmental issue are become increasingly conspicuous, and biogas is produced using organic waste
Pattern obtained wide popularization and application, biogas is that organic substance is produced through multiple-microorganism cooperative fermentation under anaerobic
Burning mixture, main component is methane (CH4) and carbon dioxide (C02).The storage of biogas currently mainly has dry type and wet
Two kinds of formula, wherein dry type membrane material gas holder gas storage is used widely, but there is the problem of gas voltage stabilizing is unstable, and the present apparatus can make
Gas holder is with the constant external methane conveying of pressure.
The content of the invention
The utility model aims to provide a kind of dry gas-holder intelligent controlling device, steady with the gas for solving prior art presence
The problem of pressure is unstable.
The technical solution of the utility model is：A kind of dry gas-holder intelligent controlling device, including feeder, its one end with
Air is connected, and is connected after the other end one decompressor of series connection between the inside and outside film of dry gas-holder, it is characterised in that described
Dry gas-holder outer membrane and inner membrance between and inside be respectively provided with pressure-detecting device and Level measurement device；In dry gas-holder
Bottom is provided with pressure relief opening, and is connected by relief tube with pressure relief device；Described pressure-detecting device and Level measurement device with
The input interface connection of one controller, the output interface of the controller is connected with decompressor and pressure relief device respectively.
Compared with prior art, the advantages of the present invention are：
1st, to be integrated in floor space in container small for all devices of the present invention, can be achieved movable and skid-mounted, it is adaptable to inhomogeneity
The biogas engineering of type, is especially facilitated for the exhausted biogas engineering of meeting aerogenesis.
2nd, system of the invention takes on-line monitoring system, the running status of whole system can be monitored in real time, in time
Adjust operational factor, it is ensured that the normal table operation of the system.
Brief description of the drawings
Fig. 1 is general structure schematic diagram of the present utility model；
Fig. 2 is overall composition block diagram of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of dry gas-holder intelligent controlling device of the utility model, including feeder 6, its one end
Be connected with air, the other end by air inlet pipe 8 connect a decompressor 3 after be connected between the inside and outside film of dry gas-holder 7,
Between the described outer membrane of dry gas-holder 7 and inner membrance and inside is respectively provided with pressure-detecting device 1 and Level measurement device 2；Dry
The bottom of formula gas holder 7 is provided with pressure relief opening, and is connected by relief tube 9 with pressure relief device 5；Described pressure-detecting device 1 and thing
Level detecting apparatus 2 is connected with the input interface of a controller 4, the output interface of the controller 4 respectively with decompressor 3 and pressure release
Device 5 is connected.
Described pressure-detecting device 1 uses pressure transmitter, and Level measurement device 2 uses ultrasonic material level meter；Decompression
Device 3 is made up of pressure-reducing valve, pressure gauge and counterweight, and counterweight is located on pressure-reducing valve, for adjusting output pressure of the pressure-reducing valve to gas holder
Power, counterweight is bigger, and output pressure is bigger, otherwise smaller；Controller 4 uses PLC or single-chip microcomputer；Pressure relief device 5 uses blower fan；For
Device of air 6 uses air blower.Controller uses PLC or single-chip microcomputer；Pressure relief device uses blower fan；Feeder uses air blower.
Operation principle of the present utility model is：
（1）Controller 4 sends enabled instruction to feeder 6, is filled with air between the inside and outside film of dry gas-holder 7, makes
External mold remains the state of heaving.
（2）The blast that decompressor 3 provides feeder 6 lowers, and meets the demand of pressure between the inside and outside film of gas holder.
（3）1 pressure detected of pressure-detecting device is transported to by signal cable.
（4）The inner membrance height that 2, Level measurement device is detected is transported to controller 4 by signal cable.
（5）Pressure relief device 5 is as superpressure insurance system, the releasing pressure automatically when pressure exceedes pressure upper limit.
Gas pressure between the inner membrance and external mold of utilization dry gas-holder 7 of the present utility model presses to inner membrance, according to right
Gas pressure in the pressure requirements adjustment of outer supply between outer membrane, so as to reach the purpose of control gas pressure.Dry gas-holder 7
The air pressure that internal air pressure starts when less than 50Pa inside feeder 6, dry gas-holder 7 stops supply dress when being higher than 1500Pa
Put 6.External mold position is ensured as ancillary method by Level measurement device 2 and pressure relief device 5 and the height of inner membrance is measured, as
The auxiliary control condition of blower fan start and stop.
The utility model can be by the operation pressure stabilization of dry gas-holder in 1000Pa, and the external duration is stable, and process is simple,
Device height is integrated, with generalization, with the feature of environmental protection.
