An inclined tube sedimentation and separation device

Abstract

The invention discloses an inclined tube sedimentation and separation device. The inclined tube sedimentation and separation device comprises more than two inclined tube main bodies arranged in an array; each inclined tube main body comprises a sediment tube and a mud slide tube fixed under the sediment tube in parallel side by side, wherein a mud slide way used for communicating each sediment tube and the corresponding mud slide tube is arranged on a side wall where the sediment tube is jointed with the mud slide tube; the top and the bottom of each mud slide tube are respectively provided with a cleaning pipe and a mud discharge pipe which are communicated with the mud slide tube. The inclined tube sedimentation and separation device has the advantages that the device is simple in structure, convenient to manufacture and low in production cost; the sediment tubes are separated from the mud slide tubes by the mud slide ways, so that the water flow disturbance to sliding mud is reduced, water and sedimentary particle suspension can flow separately, and the sedimentation effect is improved; the cleaning pipes are arranged on the tops of the mud slide tubes, so that all suspended sediment can be enabled to flow downwards along the mud slide tubes and is discharged through the mud discharge pipes; the suspended sediment is cleaned by water supplied by a high-pressure water pipe, thus being conveniently and thoroughly cleaned; the mud discharge pipes are arranged at the bottoms of the mud slide tubes, so that a non-setting suspended matter is prevented from being mixed into sediment tubes again by muddy water, and the sedimentation efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of water treatment, in particular, an inclined tube sedimentation and separation device is designed. 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 blo...

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
