Description

The water purifying equipment of up-flow reactor

The present invention relate to purification contain dissolved matter and (or) disperse the equipment of the water of thing, in this equipment, comprise a up-flow reactor, when the water that will purify contains sludge blanket, it can contact with one or more agent in up-flow reactor, this agent dissolve and (or) material that disperses brings in a kind of structure, in this structure, dissolved matter and (or) disperse thing from water, to separate; The device that has output to purify waste water in this equipment; Also has a kind of inflow water distribution system that is connected to the center water supply system, above-mentioned inflow water distribution system comprises many pipes of the pipe racks that is mounted to one or more, these pipe racks have many outflow openings, the water that purifies passes many outflow openings that separate each other, can enter space reactor, above-mentioned pipe racks is unbranched in reactor, the two ends of pipe racks are to the inflow water distribution system that openable shutoff device is housed from the feed end that will purify waste water, so the pipe racks two ends are remote each other, this shutoff device is placed on the outside of space reactor, and closes at run duration.

A kind of similar devices that can purify as the anaerobe of waste water has been disclosed in Europe number of patent application 0,090,450.

In disclosed patent, the waste water that purify contacts with so-called anaerobe mud, and this anaerobe mud is in the up-flow reactor of a kind of circle or non-circle, for example: a kind of rectangular cross section structure.Organic substance in the anaerobe mud flows into down, is included in the organic substance in the waste water, is converted into a kind of a kind of product that can get rid of from waste water, for example: a kind of product of gas, biogas.The light condition of determining of the good operation of up-flow reactor is even mixing, and with the contacting of the inflow liquid of anaerobe.

Inflow water distribution system as a pith of reactor is disclosed, and this inflow water distribution system makes the waste water that will purify, and is introduced in the water of reactor, has a kind of enough uniform liquid form on the one hand, and produces enough eddy current on the other hand.For this purpose, former inflow water distribution system is included in many pipes that horizontal plane is arranged in parallel relation, many homogeneous phases outflow opening at interval occurs, the equal diameters of these openings, and facing to the side at the bottom of the reactor.In this arrangement, the position of opening is to allow the waste water that will purify flow out direction vertically downward.The pipe that above-mentioned horizontal plane is arranged, the vertical range from the bottom of reactor can be the gross area of the outflow opening that has of every square metre of area of 10 to 300 centimetres of reactor cross-section, is the function of working process parameter.

Because the waste water that purifies often comprises suspended solid, so, flow into water distribution system and exist the possibility of being blocked.Under the situation of blocking, in order to remove clean inflow water distribution system at an easy rate, make the horizontal tube of water distribution system pass reactor wall, that is to say, not only pass the reactor wall of the supply side that flows into water distribution system, and being passed in the relative part of feed end reactor wall, general arrangement is to be closed in reactor outside opening to be connected to high pressure water system at the two ends of the pipe of reactor-side.

An object of the present invention is to provide an equipment of the open section pattern of pipe racks, this equipment comprises a kind of inflow water distribution system, and this system improves mixture in the water that will purify, and sludge blanket is maintained.For this purpose, the invention is characterized in: by flowing out the definite current outgoing direction that will purify of opening is to be tilted to down.More elaborate down of the present invention, the position of flowing out opening is: make the vertical line that flows out plane of the opening become 20 ° to 45 ° with level, preferably 29 ° to 31 °.

Because the selection of the current outgoing direction that will purify, be from flowing into the downward obliquely result of water distribution system, thereby do not have the energy of flow of the water that cuts off inflow reactor, be exactly that water slug from inflow reactor is on reactor bottom usually.Thereby from the energy of flow of the water that flows into water distribution system, optimum is to the mixing of water and sludge blanket, and is suitable to especially the mixing of the heavy mud particle that is deposited in reactor bottom and the effect in cleaning trip whirlpool.In fact, can produce best effect is to flow out direction to become about 30 ° of angles with level.

In the most preferred embodiment of equipment of the present invention, in fact this inflow water distribution system is placed on the horizontal plane of reactor bottom one segment distance of being separated by, wherein, the pipe racks that flows into water distribution system is aligned to uniform water distribution, as shown in the cross section of reactor, this pipe racks that flows into water distribution system forms a tube bank, in reactor, this pipe racks reaches the outside by the reactor cinclides at Guan Weiduan place, this Guan Weiduan is facing to the water that will purify being supplied with an end that flows into water distribution system, this equipment is characterised in that: tube bank has an aggregation infrastructure, that is: the water that purify flows into an end of water distribution system and at the pipe racks end that is positioned at the reactor wall outside, the both has aggregation infrastructure.Because converging of tube bank two ends, the interval between pipe racks is limited as much as possible, can arrive simultaneously to promote the pipe racks two ends, therefore, is provided at the device at pipe racks two ends, and for example, valve can be operated by an operator.Because flow into water distribution system usually by means of manifold, be connected to the main supplying duct of the water that will purify, the advantage that pipe racks converges is: even more than 20 meters or 20 meters under the situation of the reactor of diameter, it also can use an abundant restricted manifold of length.Thereby easy operating.

Experience indication, even mixing and flow regime in reactor in equipment of the present invention, do not need evenly to separate as the outflow opening of the water that will purify.On the per unit area of reactor cross-section, flow out on the uniform water distribution of opening, obtain good effect, that is, 1 flows out opening energy uniform water distribution on 0.5 to 3 square metre reaction cross-sectional area.We obtain a reasonable plan with these numerical value, in all practical applications, in order to realize the water that will the purify uniform water distribution as far as possible in the inflow reactor, between the effect of two opposite action, compare with less outflow number of openings, provide the outflow number of openings as much as possible, still, in order to prevent to flow out the obstruction of opening, dilated diameter as far as possible again.It is the best on 2 square meter of reactor cross-sectional areas that this scheme reaches water distribution with 1 outflow opening.

The other parameter that influences the good operation of equipment of the present invention is to flow into the vertical range of water distribution system from reactor bottom.Suppose that a known vertical range is less than 300 centimetres, so, most preferred embodiment of the present invention is characterised in that: in flowing into water distribution system, outflow opening level relatively becomes 29 ° to 31 ° outflow direction, from 15 to 20 centimetres of vertical ranges of reactor bottom, and water distribution is to about 2 square metres reactor cross-section area.On the basis of reactor,, just can really obtain an optimal results if the water that will purify is injected into speed in the reactor when approximately being 2.5 meters/per second with this structural parameters.

Now, with reference to accompanying drawing narration one embodiment of the present of invention, wherein:

Fig. 1 is the vertical view of a kind of reactor shaped portion radial cross-section of the present invention;

Fig. 2 a is the side view that water distribution system signal is gone in an expression current drainage of the present invention, is connected to reactor head and the center water supply system that obtains with its joint.

Fig. 2 b is the side view that the water distribution system signal is gone in expression one current drainage, on the reactor next door, makes water distribution system obtain the center water supply system.

Fig. 3 is a pipe shaped portion schematic cross-sectional view that flows into water distribution system, and it is supported in reactor bottom, and provides one to flow out opening nearby.

With reference to these accompanying drawings, in Fig. 1, express the reactor 10 of reactor wall 20, pipe 1,2,3,4,5,6, on 7,8 and 9 manifolds 13 that are connected to above the reactor, these pipes vertically drop in the reactor and near the bottom, and bending extends in horizontal level.After bending entered horizontal plane, the pipe of relative wall that is placed on mid-plane was outwardly-bent, thereby, on the level cross-sectionn of reactor, produce a good pipe racks water distribution effect.In pressing the reactor wall area that the A type arranges, pipeline is through to the outside, and they are with ball valve 11(Fig. 2) close pipe, and with a bead 12(Fig. 2) the spacing ring beyond the valve.

In the horizontal curvature part of pipe, pipe racks is equipped with the opening that the fluid of representing by arrow flows out direction.The waste water that purifies can be represented the excurrent general area of increase around flowing out opening in reactor, substantially with dashed circle as representative, its as a result water from pipe, flow out.

Fig. 2 further expresses, and a manifold 13 comprises that joint for pipe is connected to the main supplying duct 30 on reactor.The waste water that purifies flows out downwards from main supplying duct by manifold 13.The upper end of T type pipe joint blocks dead bead 15 with a valve 14 and one and closes.

In the embodiment that Fig. 2 b represents, the connection of the main supplying duct 30 that purify waste water is to be in the reactor next door.By a T type pipe joint, be to close at its free end with ball valve 14 and the bead 15 that blocks, all pipes pass reactor wall discretely, and the relative wall by reactor leaves reactor again.

At run duration, because the diameter of these pipe racks is quite big, the flow velocity of the water that purify is quite low, and in the outflow opening of pipe racks, because the diameter of opening is very little, so the flow velocity of water is quite high, for example: 2.5 meter per seconds.So, realized being applied in water distribution good on the whole area and good oozing closed.

The two ends of this pipe racks, can become easily unobstructed, for example:, block bead 14 and opening ball valve 11 by removing, and pipe is connected to a high-pressure water hose for the purpose of removing.This flexible pipe is connected in the bead by a kind of special suitable joint, yet this flexible pipe is connected in the pipe racks by a kind of watertight structure.

In fact, flexible pipe is equipped with a rotary nozzle.

Being illustrated in the pipe 31 among Fig. 3, is to be one of d by vertical range to support seat, and be supported in reactor bottom, d can be 10 to 30 centimetres, preferably 15 to 20 centimetres.Shown in arrow P, the outflow direction of water is that level becomes 30 ° relatively.

The nature, under the prerequisite that does not depart from the scope of the present invention, according to as mentioned above with shown in the accompanying drawing, can, can improve and change this equipment.
