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, sedimentation basin commonly used has flat flow, and radial-flow and up flow type etc. are several, and the surface loading of these sedimentation basin types is lower, thereby design volume is bigger, and deposition efficiency is lower.And according to " shallow pool theory ", in sedimentation basin, add inclined tube or swash plate, and current are in laminar condition in its inclined tube, and hydraulic radius is little, can significantly improve the efficient of sedimentation basin.Thereby tube settler is to use pond type commonly used in the Separation of Solid and Liquid precipitation at present always.
By the relation between the precipitation direction of water (flow) direction and particle, tube settler can be divided into
The lateral flow inclined plate sedimentation pond, water (flow) direction is vertical mutually with the solids precipitation direction;
The concurrent tube settler, water (flow) direction is identical with the solids precipitation direction;
The reverse flow tube settler, water (flow) direction is opposite with the solids precipitation direction.In actual application because concurrent and
Lateral flow is in water distribution, some problems of textural existence, thereby uses and more be
The reverse flow tube settler, when operation, suspended particulate substance is along the wall sedimentation of inclined tube limit, and current are catchmented by water leg after rising.At present, tube settling technology is in operation and remains a major issue, adheres to deposition easily at inclined tube inwall and top thereof.
When current flowed from bottom to top, after the suspended substance sedimentation in the water was run into inclined tube limit wall, in the wall sedimentation of inclined tube limit, and current flowed out inclined tube, enter clear water zone.Suspension in the inclined tube has certain adhesiveness, may have suspension to be attached on the wall of inclined tube limit after operation a period of time, causes the sectional area of inclined tube to reduce and increases the current upflow velocity, causes delivery turbidity to increase; And, enter in the process of clear water zone at current, because increasing, basal area make flow velocity reduce, therefore a part of suspension in the current is deposited in the surface of inclined tube, after a period of time, can stop up inclined tube, thereby influence effluent quality, thereby the regular cleaning of inclined tube is very important work in the tube settler running in the tube settler.Conventional at present purging method is that with the reduction of the water level in the pond, with the giant flushing, current can smash the flco that has generated, make alumen ustum raise up in follow-up water inlet process, influence the secondary effluent quality then.Secondary effluent quality after this cleaning way influence is cleaned 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 the conventional tube settler.
The purging method of inclined tube in the tube settler that the present invention proposes, its concrete steps are as follows:
At first, evenly lay vaporific spray system at tube settler and inclined tube top, as shown in Figure 1.This vaporific spray system comprises penstocks 1 and the some atomizers 2 that are communicated with penstocks.Tube settler 7 is when normal operation, and its water level is in the position of water leg 3, and water outlet enters out water outlet in the water channel 6 through water leg 3; Through operation after a while, after inclined tube 4 and top deposition thereof, need clean inclined tube 4.During cleaning, the water level in the tube settler is down to below the inclined tube 4 top layer planes; Then, opening pressure water pipe 1, press water in the penstocks 1 is through atomizer 2 ejections, form tiny drop at the inclined tube top, and pool current with the suspension on inclined tube top flushing landing to the inclined tube bottom, suspension after the flushing is settled down to the tube settler bottom gradually under the gravity effect, discharged outside the pond by discharge pipeline 5.
The beneficial effect that the present invention produces is, the suspension on inclined tube inwall and top thereof, form under the water droplet effect at high-pressure water spray, slip into the sedimentation basin bottom along inclined tube, suspension itself is not formed impact at whole flushing process, particle can not broken up, thereby can improve the effluent quality that inclined tube cleans, tube settler can come into operation in the short time after cleaning, has reduced the time of safeguarding tube settler, has simplified manually-operated labour intensity, thereby the present invention compares with existing mode, have the saving maintenance time, reduce hand labor intensity, improve the advantage of tube settler flushing back effluent quality.
Equally, the present invention is also applicable to the flushing of inclined-plate clarifying basin inner swash plate.
