Abstract
The utility model relates to a pressure relief protector for a methane project. The pressure relief protector consists of an anaerobic digester (1) and a gas storage cabinet (8), wherein one end of a methane pipe (7) is communicated with the anaerobic digester (1) and the other end of the methane pipe (7) stretches into the water-sealing type gas storage cabinet (8); and a blowoff valve (5) and a sludge pump (6) are arranged at the lower part of anaerobic digester (1). The pressure relief protector is characterized in that a water storage bin (3) is arranged in a container of the anaerobic digester (1); an overflow pipe (2) is connected above the water storage bin; one end of the overflow pipe is communicated with the water storage bin (3) and the other end of the overflow pipe is open in the anaerobic digester (1); a pressure relief pipe (4) is arranged at the lower part of the water storage bin (3); and the other end of the pressure relief pipe passes through the anaerobic digester (1), leads to the outside and is open. The utility model has the advantages that the pressure relief protector achieves an effect of a water sealer; the anaerobic digester and the gas storage cabinet are protected from being burst by high pressure; the anaerobic digester and the gas storage cabinet are compensated so as not to be sucked flatly by vacuum; enough water is added in the pressure relief protector for once and residual water can be automatically discharged due to system pressure association; and the pressure relief protector can work normally all the year round without maintenance and management.
Description
(1) technical field
The utility model relates to a kind of pressure protector, specifically is a kind of decompression protection device that is used for biogas engineering.
(2) background technology
Along with the development of China's energy-conserving and environment-protective cause, annual all have a large amount of large-sized biogas generating units to build.In the middle of the concrete application of these biogas generating devices, have often because the fermented feed liquid of carrying in anaeroic digestor is too much, occur since the biogas that produces too much with the accident of anaerobic jar spalling; Also because the sewage draining valve of anaeroic digestor is not in time closed or wash water valve is exposed because of winter, low temperature is freezing to cause blowdown excessive, damages anaeroic digestor, and involving accidents such as damaging gas storage holder often has generation.Above-mentioned accident is in case take place and will cause destructive harm to the large-sized biogas engineering of millions of investment constructions.In order fundamentally to avoid above-mentioned accident to take place, introduce a kind of decompression protection device that is used for biogas engineering here.
(3) technology contents
The purpose of the utility model is to overcome the defective that exists in the prior art, and a kind of decompression protection device that is used for biogas engineering is provided.
In order to realize above-mentioned purpose, the utility model is according to following technical scheme.The decompression protection device that is used for biogas engineering is made up of anaeroic digestor, gas storage holder, and an end of biogas pipe communicates with anaeroic digestor, and the other end extend in the hydrolock gas storage holder, also is provided with wash water valve and sludge pump in the bottom of anaeroic digestor.Concrete improved procedure is that water storehouse is set in anaeroic digestor, connects upflow tube above warehouse, and an end of this pipe communicates with water storehouse, and the other end is open in anaeroic digestor; Bottom at water storehouse is provided with relief tube, and the other end of this pipe leads to extraneous and open behind anaeroic digestor.
Relief tube described in the utility model two ends difference of altitude is in 700 millimeter.
Described water storehouse is cylindrical, and its sectional area is 10-20 a times of relief tube sectional area.
Superior part of the present utility model is simple in structure, cheap.Performance is comparatively superior.Normally in service at biogas engineering, the decompression protection device plays the effect of liquid packing; Anaeroic digestor or gas storage holder run into to be stranded presses when pressure is raise, and protection anaeroic digestor and gas storage holder be not by the high pressure spalling; When the feed liquid of carrying to anaeroic digestor oversteps the extreme limit height, play feed liquid superelevation position-limiting action.When the excessive formation negative pressure of blowdown,, compensation anaeroic digestor and gas storage holder are not inhaled flat by vacuum; Water in the decompression protection device, disposable filling up, unnecessary water can give off automatically because of the system pressure association; The decompression protection device places anaeroic digestor, and works better need not maintenance management throughout the year.
(4) description of drawings
Accompanying drawing is the utility model structural representation.
(5) embodiment
Concrete structure of the present utility model sees also accompanying drawing.The decompression protection device of biogas engineering, form by anaeroic digestor 1, gas storage holder 8, one end of biogas pipe 7 communicates with anaeroic digestor 1, the other end extend in the hydrolock gas storage holder 8, also be provided with wash water valve 5 and sludge pump 6 in the bottom of anaeroic digestor 1, it is characterized in that water storehouse 3 being set, above warehouse, connect upflow tube 2 in anaeroic digestor 1 inside, one end of this pipe communicates with water storehouse 3, and the other end is open in anaeroic digestor 1; In the bottom of water storehouse 3 relief tube 4 is set, the other end of this pipe leads to extraneous and open behind anaeroic digestor 1.Owing to be communication apparatus, the biogas pressure under the normal circumstances in two containers equates, is generally about 5 kPas anaeroic digestor 1 with gas storage holder 8.And the discrepancy in elevation that the water surface that is arranged in the water surface of anaeroic digestor 1 water storehouse 3 and relief tube 4 forms is 500 millimeter water column.When biogas pipe 7 blocks or other reasons when causing that biogas pressure raises in the anaeroic digestor 1, the water in the relief tube 4 rise because of pressure or the pipe that strikes the beam outside, thereby reach the purpose of anaeroic digestor 1 pressure release.
When sludge pump 6 when anaeroic digestor 1 carries the feed liquid height to reach capacity height, unnecessary feed liquid can be got rid of through relief tube 4, thereby limit feed liquid height in the anaeroic digestor 1 from upflow tube 2 upper port that are arranged on water storehouse 3 tops through water storehouse 3.
Relief tube 4 two ends difference of altitude described in the utility model are in 700 millimeter.Described water storehouse 3 is cylindrical, its sectional area be relief tube 4 sectional areas 10-20 doubly.When the wash water valve 5 of anaeroic digestor 1 was opened, the mud that is positioned at anaeroic digestor 1 bottom was discharged from wash water valve 5.In discharging,, can turn back in the anaeroic digestor 1 through biogas pipe 7, to remedy the space after liquid level descends as the biogas in the gas storage holder 8 of communication apparatus along with the liquid level in the anaeroic digestor 1 descends.Excessive or fail to close because of reasons such as failsafe valves when gaseous emission, when the biogas in the gas storage holder 8 can not be enough to replenish the space that anaeroic digestor 1 feed liquid descends, negative pressure will appear.This moment, relief tube 4 median water level descended with biogas pressure in the anaeroic digestor 1, and the water level in the water storehouse 3 rises.When forming negative pressure, the anti-water level that is lower than in the water storehouse 3 of the water level in the relief tube 4.Thereby the sectional area of relief tube 4 and water storehouse 3 differs tens times, thereby it is but very little to form the negative pressure waterhead, and outside air is easy to enter water storehouse 3 through relief tube 4, enter in the anaeroic digestor 1 through upflow tube 2, thereby the compensation liquid level descends and forms negative pressure space again.
