Abstract
The utility model discloses a water seal device for a UASB (Upflow Anaerobic Sludge Blanket) reactor, which comprises a tank body, wherein the tank body is filled with water; a sealing cover is arranged at the upper part of the tank body; two gas inlets and a gas outlet are formed in the sealing cover; two gas inlet pipes are arranged at the two gas inlets; and one gas inlet pipe extends into the water, and the other extends into the water to the bottom of the tank body. The water seal device for the UASB reactor can effectively prevent boiling caused by uneven gas intake due to suck-back of water in case of a small gas output. While convenient to overhaul and easy to observe and use, the water seal device can always effectively guarantee the height of a gas chamber of a three-phase separator in a UASB, so that methane can keep constant pressure. The water seal device effectively solves the problems that current commonly used water seal devices cannot solve, thereby expecting extremely good industrial application.
Description
Technical field
The utility model relates to a kind of water seal arrangement of UASB reactor drum, belongs to technical field of sewage.
Background technology
In the biological treatment of industrial organic waste water, up-flow anaerobic sludge blanket (UASB) reactor drum has simple in structure, anaerobic digestion efficient advantages of higher.Through the UASB reactor drum, reactor bottom has a high density, highly active Sludge Bed to sewage from bottom to top, and it is biogas and dioxide gas that the majority of organic pollutants in the sewage is degraded to methane through anaerobically fermenting during this time; And the collection of the closed UASB reactor drum generation of WWT biogas needs a kind of water seal arrangement that makes biogas keep constant voltage; This kind water seal arrangement generally by environmental protection company oneself design, is an inlet pipe and gos deep under the gauging line certain in the device, and another root escape pipe is positioned at the device top; Because producing biogas, closed UASB has unstable; Will cause water seal arrangement inlet end one one to seethe with excitement frequently, severe patient is more arranged, because the reservation of inlet pipe superelevation is less; Can cause the interior water suck-back of device to go in the UASB, thereby lose the effect that makes biogas keep constant voltage.
Summary of the invention
The purpose of the utility model is to provide a kind of suck-back that can effectively prevent owing to water in the UASB reactor drum gas production rate hour water seal arrangement; Thereby can effectively guarantee triphase separator air chamber height in the UASB, make biogas keep the water seal arrangement of the UASB reactor drum of constant voltage.
The water seal arrangement of the UASB reactor drum of the utility model; The top of said tank body is provided with sealing cover, and said sealing cover is provided with two inlet mouths and a venting port, and said two inlet mouth places are provided with two inlet pipe; One of which is deep into the underwater, and it two is deep into the underwater and extends to tank base.
For preventing the uneven boiling that causes of air inlet, be provided with in the said tank body to be used for anti-sealing ebullient steel screen layer.
For overhauling convenient the use, the bottom of said tank body is provided with the drain that is used for the emptying tank body.
Said tank body middle part is provided with water-in and overflow water outlet.
Said overflow water outlet is provided with and is used for the graduated tube that the water overflow detects, and can grasp liquid level situation in the tank body at any time.
The water seal arrangement of the UASB reactor drum of the utility model can effectively prevent gas production rate hour water suck-back, the uneven and boiling that causes of air inlet, and it is convenient to have a maintenance; Being easy to observation uses; All the time can effectively guarantee triphase separator air chamber height in the UASB, make biogas keep constant voltage, therefore; Effectively solve the indeterminable problem of generally using at present of water seal arrangement, had fabulous prospects for commercial application.
