Continuous precipitation separation inclined tube

Abstract

The invention discloses a continuous precipitation separation inclined tube. The continuous precipitation separation inclined tube comprises a precipitation tube and a mud sliding tube, wherein the mud sliding tube is parallelly and fixedly arranged under the precipitation tube side by side; an included angle between the precipitation tube and the horizontal plane is alpha; a mud sliding passage which is communicated with the precipitation tube and the mud sliding tube is arranged on the side wall, which is in fit with the mud sliding tube, of the precipitation tube; a cleaning tube and a mud discharging tube which are communicated with the mud sliding tube are respectively arranged at the top part and the bottom part of the mud sliding tube. The continuous precipitation separation inclined tube disclosed by the invention has the advantages that the structure is simple, the manufacturing is convenient, and the production cost is low; the mud sliding passage is used for separating the precipitation tube and the mud sliding tube, so that the influence of water flow on mud sliding can be reduced, separated flowing of water flow and precipitated / suspended matters is realized, and the precipitation effect is increased; since the cleaning tube is arranged at the top part of the mud sliding tube, on one hand, precipitated / suspended matters are enabled to be totally and downwards discharged through the mud discharging tube along the mud sliding tube, and on the other hand, water can be supplied to clean the mud sliding tube by utilizing a high-pressure water tube when the mud sliding tube is silted up; since the mud discharging tube is arranged at the bottom part of the mud sliding tube, discharged precipitated / suspended matters are enabled to fall into a suspended matter precipitation and accumulation area, and the precipitation efficiency is increased.

Description

Technical field: [0001] The invention relates to the technical field of water treatment, in particular designing a continuous sedimentation and separation inclined pipe. Background technique: [0002] In traditional water treatment, an inclined structure (inclined tube or inclined plate) arranged in a water treatment tank is generally used to separate water and suspended solids. The traditional oblique structure sedimentation technology belongs to the counterflow setting, that is, the water flow and the sediment coexist in the same pipeline environment, the clear water flows upward, and the suspended matter sinks downward; however, due to the long sedimentation path, the upward flowing water is easily disturbed and Suspended sediments that sink down the direction lead to poor water quality after treatment, resulting in poor water quality after treatment, and the so-called alum running phenomenon; and it is easy to deposit on the top of the inclined structure and gradually bl...

Problems solved by technology

The traditional oblique structure sedimentation technology belongs to the counterflow setting, that is, the water flow and the sediment coexist in the same pipeline environment, the clear water flows upward, and the suspended matter sinks downward; however, due to the long sedimentation path, the upward flowing water is easily disturbed and Suspended sediments that sink down the direction lead to poor water quality after treatment, resulting in poor water quality after treatment, and the so-called alum running phenomenon; and it is easy to deposit on the top of the inclined structure and gradually block the pipeline. In order to prevent the pipeline from clogging, water treatment needs to be strengthened In the upper flocculation process, the cost of water treatment is high

There is a kind of sedimentation inclined pipe in the market. A partition with mud discharge holes is installed inside the inclined pipe, which divides the inclined pipe into upper and lower spaces. The suspended sediments fall into the inclined pipe below the partition through the mud discharge hole. In the pipe; although this kind of inclined pipe can temporarily separate water and mud, when the water flow rises along the inclined pipe above the partition, part of the water will enter the inclined pipe below the partition through the mud discharge hole to form a disturbance, and the suspended The sediment is stirred up again, and the sedimentation effect is poor; the muddy water inlet of the sedimentation inclined pipe is close to the sewage outlet of the suspended sediment, and the muddy water will re-involve part of the suspended sediment into the inclined pipe, reducing the sedimentation efficiency; in addition , part of the water flow will rise along the inclined pipe under the partition, take away part of the suspended sediment, and discharge it together with the clear water, affecting the sedimentation effect
