Description
Technical field
The present invention relates to a kind of methane saving device.
Background technique
Low pressure marsh gas stores and utilization is the chemically treated class important technology of organic substance anaerobic organism, be usually used in the aspects such as anaerobic waste water processing, anaerobic sludge digestion, crops leftovers, rubbish anaerobism composting and biogas comprehensive utilization, the pressure that anaerobic treatment produces biogas is lower, be generally 2000～4000Pa, before utilizing, relate to link and the facilities thereof such as storage, adjusting and purification.The conventional gas-saving device of low pressure marsh gas cabinet has at present: wet gasholder (gas hood floats), dry gasholder (barrier film air chamber).
Traditional unsteady gas hood is generally comprised of following substantial section: floating cover and tower joint, guide rail introduction, balancing weight, position-limit mechanism, water seal hanging ring, safety valve, pressure gauge and turnover tracheae, generally need to rely on floating cover and the lifting in the tank of bottom of tower joint to regulate, store gas.
There are some problems in traditional unsteady gas hood, for example: system forms with self structure more complicated, and high to the required precision of making, installation and adjustment, the problem of installation and maintenance causes operation troubles; Construction investment is large; Take up room large.
Because biogas air pressure is lower, so current some are applicable to the device of middle high-pressure gas, cannot directly divert biogas field again, and in prior art, be all simple decompression function, can not play voltage stabilizing, more can not play the function of supercharging.
Summary of the invention
The invention provides a kind of methane saving device, can control biogas flow, balance and adjusting biogas pressure.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: methane saving device, comprise housing, on housing, lower end is provided with opening and opening is provided with connection set, housing middle and lower part is followed successively by inferior pyramidal part and lower linking tube, in lower linking tube, be provided with spool guide sleeve, between spool guide sleeve and lower linking tube inwall, being provided with guide sleeve supports, in spool guide sleeve, be equipped with floating plug, floating plug top is fixedly equipped with orifice plate, the shape of orifice plate is consistent with the shape of cross section of inferior pyramidal part corresponding position, the top of floating plug is provided with floating valve core cap, floating plug covers to be provided with adjusts heavy counterweight.
Described housing comprises upper and lower tapering part, the big cone opening docking of upper and lower tapering part is also fixed with pipe flange, the tiny cone opening of upper and lower tapering part is to being equipped with upper and lower adapter, and the upper end of upper connecting tube and the lower end of lower linking tube are respectively equipped with pipe flange suitable for reading and end opening pipe flange as connection set; Orifice plate is arranged on the lower pyramid mouth place of inferior pyramidal part.
The heavy counterweight of described tune is ring weight.
Described spool guide sleeve lower end is 13-17mm to the distance of housing bottom.
Described pipe flange joint is provided with sealing gasket.
The present invention can control biogas flow, balance and adjusting biogas pressure, simple structure, take up room little, manufacturing cost is low, maintenance requirement is few, has departed from heavy steel structure, with exquisite device structure bring engineering investment and the duration on economization.Under the mating reaction of inferior pyramidal part of the present invention, orifice plate, the heavy counterweight of tune, floating plug, only allow gas unidirectional to flow, pass through successively lower linking tube, inferior pyramidal part, upper conical part, upper connecting tube 7.Movable part of the present invention is the floating plug in spool guide sleeve, and what play balanced action is to adjust heavy counterweight.The present invention is specially adapted to hypobaric.
The invention solves the following problem that traditional biogas balance and controlling device exist:
(1) the invention solves technical construction complexity, requiring of design, making and installation precision is high, the problem that the construction period is long.
(2) the invention solves the large and large problem that takes up room of major project equipment investment.
(3) the present invention will solve because the large problem of working service workload that the reasons such as elevating control, gas displacement, antifreeze anticorrosion and safety and fire prevention cause.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Embodiment: as shown in Figure 1, methane saving device, comprises housing 4, and housing 4 upper and lower end openings are provided with connection set, on the interior floating plug 2 of housing 4, be fixedly equipped with orifice plate 3, orifice plate 3 downsides are provided with by guide sleeve and support the 11 spool guide sleeves 1 that are fixedly connected with housing 4; In the hole of spool guide sleeve 1 and orifice plate 3, be equipped with floating plug 2, the top that is positioned at the floating plug 2 of orifice plate upside is provided with floating valve core cap 10, floating plug covers to be provided with adjusts heavy counterweight, adjusts heavy counterweight to comprise adjusted counterweight 8, lower adjusting counterweight 9 in the present embodiment, is ring weight.Housing 4 comprises upper and lower tapering part, the big cone opening of upper and lower tapering part docks and uses pipe flange 5 fixing, pipe flange 5 joints are provided with sealing gasket 6, the tiny cone opening of upper and lower tapering part is to being equipped with upper and lower adapter 7,14, and the lower end of the upper end of upper connecting tube 7 and lower linking tube 14 is respectively equipped with pipe flange 12 suitable for reading and end opening pipe flange 13; Orifice plate 3 is arranged on the lower pyramid mouth place of inferior pyramidal part.Spool guide sleeve 1 lower end is 13-17mm to the distance of housing 4 bottoms, and in the present embodiment, distance is 15mm.
When entering the gas flow increase of lower linking tube 14, floating plug 2 rises because gas pressure increases, until pressure decreased and floating plug 2 gravitational equilibriums, when entering the gas flow minimizing of lower linking tube 14, floating plug 2 declines, until pressure increases and floating plug 2 gravitational equilibriums.For different biogas, store, utilize system, when pressure need to be selected between 2000～4000Pa, quantity and the weight thereof of capable of regulating adjusted counterweight 8, lower adjusting counterweight 9 change system pressure.
