Description
Technical field
The invention relates to a kind of UASB water-sealed tank, specifically, relates to a kind of water-sealed tank of the UASB of being conducive to continous-stable aerogenesis.
Background technology
UASB is that upflow anaerobic sludge blanket reactor is a kind of high-efficiency sewage anaerobic treatment reactor, be widely used in now the processing of high concentrated organic wastewater, there is energy consumption low, stable, the advantages such as sludge output is low, its effective clearance for COD can reach more than 80%, the sewage reactor of intaking from bottom, flowed out by top, microorganism in reactor bottom granule sludge district and suspended sludge area is decomposed the organism in sewage in a large number, thereby produce a large amount of methane gass, collecting pipe via triphase separator top is collected, by discharging the comprehensive utilization such as burn after water-sealed tank, existing UASB water-sealed tank structure is too simple, often only play a fire-retardant effect, accurate not for the pressure-controlling that produces methane gas, there is no protector, operate the problems such as easy not.
For example, Granted publication number is the water seal arrangement that the use new patent of CN202542948U discloses a kind of UASB reactor, it comprises that inside is equipped with the tank body of water, the top of described tank body is provided with sealing cover, described sealing cover is provided with two inlet mouths and a venting port, described two inlet mouth places are provided with two inlet pipe, and one is deep into underwater, and it two is deep into underwater and extends to tank base.In described tank body, be provided with the steel screen layer for anti-sealing boiling.Described tank body middle part is provided with water-in and overflow water outlet, and described overflow water outlet is provided with the graduated tube detecting for water overflow.This equipment does not arrange safety-valve, if can allow tank body internal pressure increase when outlet pipe and follow-up unit break down, thereby triphase separator is produced to punching level, makes core processing unit impaired yet.Liquid level in tank body is checked with glass graduated tube in the overflow water exit of this equipment, can be frozen in, thereby tank level is raise at north of china in winter, makes the pressure that triphase separator bears become large, damages its structure.This equipment enters venting port for preventing liquid, and the steel screen layer that anti-sealing boiling is set has strengthened production cost.
Utility model content
The utility model is for defect and the deficiency of prior art, provide a kind of simple in structure, cost is low, be conducive to the water-sealed tank of UASB continous-stable aerogenesis.
The technical solution of the utility model is: a kind of novel UASB water-sealed tank, comprise tank body, tank interior is equipped with water, tank body top is provided with inlet mouth, air outlet and top safety valve, tank base is provided with evacuation port, evacuation port is connected with bottom exhaust-valve by emptying pipe, described inlet mouth place is provided with intake ducting, intake ducting extend into underwater and extends to tank base, described air outlet place is connected with outlet pipe, described tank wall is provided with venting port and the liquidometer that is provided with set water level, described venting port is connected with tank body vent valve by gas exhaust duct, the sidewall of described tank base is provided with water port, described water port is connected with liquid level holdout device.
Preferably, described liquid level holdout device is inverted U-shaped drainage pipeline, and on the lower wall on described inverted U-shaped drainage pipeline top and liquidometer, set set water level is in sustained height.
Preferably, described liquid level is counted magnetic turnover plate type liquidometer.
The beneficial effects of the utility model are:
1, the utility model efficiently solves UASB continous-stable aerogenesis problem, and intake ducting is arranged on pot bottom, and collecting pipe, in tank top, makes collecting pipe large with the liquid level discrepancy in elevation in tank, does not therefore need to increase other facilities and solved biogas and go out the problem of band of gas water;
2, enter in the biogas of tank body with moisture, increase in time can make the liquid level in tank body raise, make the pressure that triphase separator bears become large, damage its structure, therefore just need to there is people regularly the water in tank body to be put into set liquid level, and being set at the bottom of arc push pipe, the inverted U-shaped drainage pipeline parallel with set water level in tank body fundamentally solve this problem, in tank body, unnecessary water can be discharged by pipeline self, control for liquid level is accurate, do not need to arrange separately personnel and regularly operate, reduced the error of manual operation yet;
3, tank body top arranges safety valve, in the time exceeding design pressure, the very first time will be opened the pressure reducing in tank body automatically, effectively prevent that the follow-up unit of the collecting pipe build-up of pressure that goes wrong from rising sharply for the impact of triphase separator, ensures core processing unit;
4, liquidometer adopts magnetic turnover plate type liquidometer to efficiently solve the common liquidometer of the north of china in winter problem that cannot work that is frozen in;
5, at the bottom of tank, exhaust-valve pipeline directly extend into Chi Tizhong, the liquid of discharge is discharged to pond body and has avoided the situation of secondary pollution to occur;
6, tank body vent valve has been taken into account the function of exhaust and filled with water, in the time that triphase separator overhauls, opens and avoids pressing the phenomenon of collapsing to occur triphase separator because producing negative pressure simultaneously.
