It is preferred that, the main adjacent with two is connected respectively for the two ends of the sparge pipe, the water distribution between each two adjacent main
The quantity of pipe is several, and these sparge pipes are equally spaced along main.
It is preferred that, the bottom surface of the water distribution pipe network and liquid storage cylinder is at a distance, and the perforate of the distributing hole is directed downward.
It is preferred that, the perforate direction of the distributing hole tilts horizontal by an angle and makes the perforate court of the distributing hole
Oliquely downward.
It is preferred that, the water inlet of the water inlet pipe is arranged on the top of liquid storage cylinder.
It is preferred that, the water inlet of the water inlet pipe is the 2/3 ~ 3/4 of liquid storage cylinder height with the distance of liquid storage cylinder bottom surface.
The beneficial effects of the invention are as follows：In the present invention, by setting water distribution pipe network in liquid storage cylinder, opened on the net in water distributor
Establishing water hole, its cloth water area is big, water distribution is uniform, it can be ensured that mud mixture is uniformly distributed in liquid storage cylinder, and is effectively protected
The physical state of mud mixture even suspension in liquid storage cylinder is held, the effect of hydrolysis acidification reaction is optimized.Meanwhile, it is of the invention
Water-distributing device is simple in construction, with low cost, with good prospects for commercial application.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation at another visual angle of the invention.
Embodiment
1~Fig. 2 of reference picture, the present invention is a kind of reactor for hydrolysis and acidification, including the He of reactor body 1 with liquid storage cylinder
The water-distributing device on reactor body 1 is arranged on, water-distributing device includes
Water distribution pipe network, is arranged in liquid storage cylinder, and distributing hole is offered on the net in water distributor；
Water inlet pipe 31, is connected with water distribution pipe network, for liquid to be delivered into water distribution pipe network.
When reactor for hydrolysis and acidification works, the liquid such as sewage is entered in water distribution pipe network by water inlet pipe 31, Ran Houtong
Cross and be arranged on the online distributing hole inflow liquid storage cylinder of water distributor, because these liquid flowed out by distributing hole have certain speed
Degree, into liquid storage cylinder in can stir the sewage and activated sludge in liquid storage cylinder, mud mixture in liquid storage cylinder is uniformly divided
Cloth, and effectively keep the physical state of mud mixture even suspension in liquid storage cylinder.In the present invention, by being set in liquid storage cylinder
Water distribution pipe network, distributing hole is opened up in water distributor on the net, and its cloth water area is big, and water distribution is uniform, can effectively ensure mud in liquid storage cylinder
Aqueous mixtures are uniformly distributed, and effectively keep the physical state of mud mixture even suspension in liquid storage cylinder, optimize hydrolysis
The effect of acidification reaction, even if part distributing hole is blocked, also will not produce too much influence to water distribution.Meanwhile, the present invention
Water-distributing device it is simple in construction, it is with low cost, with good prospects for commercial application.
Water distribution pipe network includes some mains 21 radially distributed around liquid storage cylinder bottom centre and is arranged on main 21
On sparge pipe 22, each sparge pipe 22 connected by main 21 with water inlet pipe 31, and distributing hole is arranged on sparge pipe 22.Sparge pipe
The main 21 adjacent with two is connected respectively at 22 two ends, and the quantity of the sparge pipe 22 between each two adjacent main 21 is several,
And these sparge pipes 22 are equally spaced along main 21.The liquid such as sewage are delivered to main 21 by water inlet pipe 31, then will by main 21
It is sent to sparge pipe 22, can ensure that the flow in each sparge pipe 22 is identical with pressure as far as possible, and then ensure by each
The flow velocity of the liquid of distributing hole outflow is identical with flow, is uniformly distributed the mud mixture in liquid storage cylinder.
In the present invention, the bottom surface of water distribution pipe network and liquid storage cylinder is at a distance, and the perforate of distributing hole is directed downward.If
Upward, the impurity in liquid storage cylinder is easily deposited in distributing hole to result in blockage the opening direction of distributing hole, and distributing hole
Perforate is directed downward this and can avoided this type of circumstances from happening.In addition, the perforate of distributing hole is directed downward, come out from distributing hole
Liquid sprays downwards, bumps against the bottom surface of liquid storage cylinder, the liquid of injection rebounded by the reaction force from liquid storage cylinder bottom surface to
Upper flowing, can so be stirred positioned at deposits such as the activated sludge of liquid storage cylinder bottom surface, can be prevented effectively from activated sludge in reaction
Device bottom deposit, improves mixed effect, and can turbulization, mix activated sludge and sewage more uniform.
Further, the perforate direction of distributing hole tilts horizontal by an angle and makes the perforate of distributing hole towards under tiltedly
Side, can so reduce the liquid come out from distributing hole and spray downwards and hit the kinetic energy that liquid storage cylinder bottom surface is lost, can also make
These fluid jets come out from distributing hole keep concentrating, it is ensured that there is liquid enough kinetic energy to allow it to rise to liquid storage
The top of chamber, making the activated sludge and sewage on liquid storage cylinder top can also be well mixed.
In the present invention, water pump 32 is provided with water inlet pipe 31, the water inlet of water inlet pipe 31 is arranged on the top of liquid storage cylinder, entered
The delivery port of water pipe 31 is connected with main 21.Water-distributing device is moved towards using the flowing of upper entering and lower leaving so that in whole liquid storage cylinder
Liquid is involved in mixed flow, further ensures that being uniformly distributed for mud mixture in liquid storage cylinder.It is preferred that, water inlet pipe 31 enters
The distance of the mouth of a river and liquid storage cylinder bottom surface is the 2/3 ~ 3/4 of liquid storage cylinder height, and water inlet is set and both can ensure that entirely in this position
Liquid in liquid storage cylinder is involved in mixed flow, air can also be avoided to be inhaled into and influence acidification reaction effect.
Above-described embodiment is the preferred scheme of the present invention, and the present invention can also have other embodiments.The technology of this area
Personnel put in the head without prejudice to spirit of the present invention can also make equivalent variations or replacement, and these equivalent modifications or replacement are wrapped
It is contained in the scope set by the application claim.
