Abstract
The invention belongs to the technical field of water treatment and particularly relates to a method of flushing inclined tubes in an inclined-tube sedimentation basin. A spray system is evenly laid above the inclined tubes in the inclined-tube sedimentation basin and comprises a pressure water pipe and a plurality of spay nozzles communicated with the pressure water pipe. During cleaning, suspensions on the walls and upper portions of the inclined tubes are cleaned by lowering the water level of the inclined-tube sedimentation basin to be below the top plane of the inclined tubes, opening the pressure water pipe, allowing the pressure water inside to be sprayed through the spray nozzles and allowing drops of spray to slide down to clean the inclined tubes; in the flushing process, particles are not scattered; accordingly, quality of outgoing water is improved, the time of maintaining the inclined-tube sedimentation basin is shortened, and labor intensity of manual operation is reduced. The method is also applicable to flushing inclined plates in an inclined-plate sedimentation tank.
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to the purging method of inclined tube in a kind of tube settler.
Background technology
In water treatment technology, often need Separation of Solid and Liquid, utilize the gravitational settling of suspended solid to be used for the equipment of separate suspended solid and be called sedimentation basin.Usually, conventional sedimentation basin has flat flow, and radial-flow and up flow type etc. are several, and the surface loading of these sedimentation basin types is lower, and thus design volume is comparatively large, and deposition efficiency is lower.And according to " shallow pool theory ", in sedimentation basin, adding inclined tube or swash plate, its oblique in-pipe flow is in laminar condition, and hydraulic radius is little, can significantly improve the efficiency of sedimentation basin.Thus, tube settler commonly uses pond type conventional in Separation of Solid and Liquid precipitation at present.
By the relation between water (flow) direction and the precipitation direction of particle, tube settler can be divided into
side flow lamella, it is mutually vertical that water (flow) direction and particle precipitate direction;
concurrent tube settler, it is identical that water (flow) direction and particle precipitate direction;
reverse flow tube settler, it is contrary that water (flow) direction and particle precipitate direction.In actual application, due to concurrent and
lateral flow, in water distribution, some problems of textural existence, is thus applied and more is
reverse flow tube settler, operationally, suspended particulate substance is along the wall sedimentation of inclined tube limit, and current are catchmented by water leg after rising.At present, pipe chute deposition technique is in operation and remains a major issue, easily adheres to deposition at inclined tube inwall and top thereof.
When current flow from bottom to top, after the suspended substance sedimentation in water encounters inclined tube limit wall, in the wall sedimentation of inclined tube limit, and current flow out inclined tube, enter clear water zone.Suspension in inclined tube has certain adhesiveness, suspension may be had to be attached on the wall of inclined tube limit after running a period of time, causes the sectional area of inclined tube reduce and increase current upflow velocity, causes delivery turbidity to increase; And, enter in the process of clear water zone at current, because basal area increases, flow velocity is reduced, therefore a part of suspension in current is deposited in the surface of inclined tube, after a period of time, can block inclined tube, thus affect effluent quality, thus in tube settler, the periodic cleaning of inclined tube is work very important in tube settler running.The purging method of current routine is, is reduced by the water level in pond, and then rinse with giant, current can smash the flco generated, and alumen ustum is raised up in follow-up water inlet process, affects secondary effluent quality.Secondary effluent quality after this cleaning way impact cleaning, needs the off-time longer, and labor intensive.
Summary of the invention
The object of the present invention is to provide the purging method of inclined tube in a kind of tube settler, to solve the problem of inclined tube top layer deposition in conventional tube settler.
The purging method of inclined tube in the tube settler that the present invention proposes, its concrete steps are as follows:
First, vaporific spray system is evenly laid at tube settler and inclined tube top, as shown in Figure 1.Some atomizers 2 that this vaporific spray system comprises penstocks 1 and is communicated with penstocks.Tube settler 7 is when normally running, and its water level is in the position of water leg 3, and water outlet enters water outlet in outlet canal 6 through water leg 3; Through operation after a while, when after inclined tube 4 and top deposition thereof, need to clean inclined tube 4.During cleaning, the water level in tube settler is down to below inclined tube 4 top-most-surface plane; Then, opening pressure water pipe 1, press water in penstocks 1 sprays through atomizer 2, tiny drop is formed at inclined tube top, and pool current by the suspension on inclined tube top flushing landing to inclined tube bottom, suspension after flushing under gravity, is settled down to bottom tube settler gradually, is discharged outside pond by discharge pipeline 5.
The beneficial effect that the present invention produces is, the suspension on inclined tube inwall and top thereof, under high-pressure water spray forms water droplet effect, slip into bottom sedimentation basin along inclined tube, suspension itself is not formed at whole flushing process and impact, particle can not be broken up, thus the effluent quality of inclined tube cleaning can be improved, tube settler can come into operation in the short time after cleaning, decrease the time of safeguarding tube settler, simplify manually-operated labour intensity, thus the present invention is compared with existing mode, there is saving maintenance time, reduce hand labor intensity, improve the advantage that tube settler rinses rear effluent quality.
Equally, the present invention is also applicable to the flushing of inclined-plate clarifying basin inner swash plate.
Accompanying drawing explanation
Fig. 1 is that inclined tube of the present invention rinses schematic diagram.
number in the figure:1 is penstocks, and 2 is atomizers, and 3 is water legs, and 4 is inclined tubes, and 5 is discharge pipelines, 6 outlet canals, and 7 is tube settlers, and A is sedimentation basin water outlet water level when normally working, and B is inclined tube top plane.
Detailed description of the invention
As shown in Figure 1.First, evenly lay vaporific spray system at tube settler and inclined tube top, some atomizers 2 that this vaporific spray system comprises penstocks 1 and is communicated with penstocks.The diameter of penstocks 1 is 40mm, and atomizer 2 quantity is 16.Tube settler 7 when normally running, the position of its water level A in FIG, water outlet enters water outlet in outlet canal 6 through water leg 3; Through operation after a while, when after inclined tube 4 and top deposition thereof, need to clean inclined tube 4.During cleaning, water level in tube settler is down to below inclined tube 4 top-most-surface plane by A, as shown in B in Fig. 1, then, opening pressure water pipe 1, press water in penstocks 1 sprays through atomizer 2, form tiny drop at inclined tube top, and pool current by the suspension on inclined tube top flushing landing to inclined tube bottom, the suspension after flushing under gravity, can be settled down to bottom tube settler gradually, be discharged outside pond by discharge pipeline 5.
