Abstract
A moderate temperature UASB reactor water distribution device in diameter of more than 15 meter comprises a moderate temperature UASB reactor, a plurality of U shaped water distribution branch pipe sets (1) at the bottom of the moderate temperature UASB reactor, wherein a branch pipe (7) on the U shaped water distribution branch pipe sets (1) belong the moderate temperature UASB reactor bottom range is connected with a water inlet manifold (8). The water distribution device is especially suitable for the moderate temperature UASB reactor in diameter of equal to or more than 15 meter and the water distribution at the bottom of the reactor is uniform and the water power rotary current is quickly formed and the water is mixed and the full-tank homogeneration effect is good; when the individual branch pipe is blocked, the on-line clear is easily realized; when the large-volume steeliness column shaped moderate temperature UASB reactor using the technique is in regular service, the COD average removal rate is stably above 70% and the firedamp generation index is 0.5m<3> firedamp/KgCOD.
Description
Technical field
The present invention relates to the energy-saving and emission-reduction technical field of waste water processing, diameter is greater than moderate temperature UASB reactor water distribution device in 15 meters specifically.
Background technology
The monomer volume surpasses 3000 cubic metres, and diameter is greater than 15 meters middle moderate temperature UASB reactor, and the quality of its treatment effect depends on the degree of uniformity of Chi Dibushui must make constituent parts area flooding quantity equal substantially to a great extent, prevents short circuit and surface load inequality; Must satisfy Sludge Bed waterpower and mix needs, will consider the biogas stirring that waterpower is mixed and produced simultaneously; Must be easy to observe the latch up phenomenon of water inlet pipe, be easy to remove if take place to stop up.
Yet, the middle moderate temperature UASB reactor bottom water distribution that the monomer volume is bigger generally all is that a dendroid water distributor is set at present, and raw waste water is pumped into by a total water inlet, and the aperture from the dendroid range pipe flows out, the every terminal shutoff of arm, the water distribution aperture opening on the arm vertically downward.There is following problem in this water distribution manner:
1. the every terminal shutoff of range pipe causes the bigger middle moderate temperature UASB reactor water distribution of bottom area to be not easy evenly to have dead angle, dead band;
2. the every terminal shutoff of range pipe can not form the cycling stream water distribution, and range pipe very easily stops up, and the obstruction point is difficult for finding, is difficult for clear and coherent;
Water distribution aperture opening on the arm all vertically downward, water inlet can not form rotating fluid rapidly and carry out waterpower and mix, and causes the organic pollutant in the water fully not contact with microorganism, thereby influences the reactor for treatment effect.
Summary of the invention
The objective of the invention is to develop a kind of in addition improved on ins and outs, can to overcome existing dendroid water distribution manner insufficient, not only even water distribution, satisfy waterpower blended needs in the reactor, and when a range pipe takes place to stop up, be easy to find, be easy to clear and coherent timely and effectively diameter greater than moderate temperature UASB reactor water distribution device in 15 meters.
Diameter of the present invention is greater than moderate temperature UASB reactor water distribution device in 15 meters, comprise: middle moderate temperature UASB reactor, middle moderate temperature UASB reactor inner bottom part is equipped with a plurality of U-shaped range pipe groups 1, and the arm 7 on the U-shaped range pipe group 1 outside middle moderate temperature UASB reactor bottom range links to each other with water inlet manifold 8.
U-shaped range pipe group 1, comprise: two range pipe a, b, the end of two range pipe a, b links to each other with arc liaison tube 9, have water distribution aperture 3 on range pipe in middle moderate temperature UASB reactor bottom range and the arc liaison tube 9, gate valve 4, arm 7 are housed on the range pipe outside middle moderate temperature UASB reactor bottom range, and the range pipe port is connected with blind flange 5.
Range pipe is offset direction and the consistent hole of deviation angle with water distribution aperture 3 on the arc liaison tube 9, and its hole is in vertical direction with 5～50 ° of angles.
Diameter of the present invention is achieved in that greater than moderate temperature UASB reactor water distribution device in 15 meters opens gate valve 6, gate valve 4 successively, because full pond water distribution aperture 3 offset directions and deviation angle unanimity, water distribution aperture 3 is uniformly distributed on a plurality of U-shaped range pipe groups 1 at a certain distance, stagnant water, dead band have been avoided, guarantee full pool surface load evenly, can form waterpower rotating fluid mixing stirring rapidly, organic pollutant in the water is into fully contacted and the removal of being degraded with microorganism, improve the reactor for treatment effect; If certain root range pipe in the U-shaped range pipe group 1 (as range pipe a) when taking place congestion affects to the reactor for treatment effect, the UASB reactor needs stop production to overhaul, close the gate valve 6 on the arm 7 that links to each other with the range pipe a that stops up this moment, open the blind flange 5 on the range pipe a and connect flexible pipe to plant area's hold well, the pumping pressure cleaning water is never stopped up end (being range pipe b) and is oppositely entered range pipe a again, it is carried out online backflushing washes, promptly needn't remove range pipe, flushing waste water drains into plant area's sink drainage by flexible pipe and gets final product.
Diameter of the present invention greater than the advantage of moderate temperature UASB reactor water distribution device in 15 meters is: be particularly suitable for the middle moderate temperature UASB reactor of diameter greater than 15 meters (containing), make the reactor bottom even water distribution, can form the waterpower rotating fluid rapidly and mix, complete jar homogenizing effect is good; When indivedual range pipes take place to stop up, realize online clear and coherent easily; Used in the big volume steel cylindricality of the art of this patent moderate temperature UASB reactor when normal operation, the COD average removal rate can be stablized and reaches more than 70%, produces the biogas index and reaches 0.5m
3Biogas/KgCOD.
