In conventional water treatment, an inclined structure (inclined pipe or inclined plate) arranged in a water treatment tank is generally adopted to separate water from suspended matters. The traditional inclined structure sedimentation technology belongs to the arrangement of counter current, namely, water flow and sediment are co-located in the same pipeline environment, clear water flows upwards, and suspended matters sink downwards; however, because the settling path is long, suspended matter sediments sliding and settling downwards are extremely easy to disturb and take away by water flow flowing upwards, the water quality after treatment is poor, and the so-called alum leakage phenomenon occurs; and the pipeline is easy to be gradually blocked by deposition on the top of the inclined structure, and the upper flocculation process in water treatment needs to be enhanced in order to prevent the pipeline from being blocked, so that the water treatment cost is high. A sedimentation inclined tube appears in the market, a partition plate provided with a sludge discharge hole is arranged in the inclined tube, the inclined tube is divided into an upper space and a lower space, and suspended matter sediments fall into the inclined tube below the partition plate through the sludge discharge hole; although the inclined pipe can temporarily separate water from mud, part of water flows into the inclined pipe below the partition plate through the mud discharging hole to form disturbance in the process of rising along the inclined pipe above the partition plate, suspended matter sediments are stirred again, and the sedimentation effect is poor; the turbid water inlet of the sedimentation inclined tube is close to the sewage discharge outlet of the suspended matter sediment, and the turbid water can re-roll part of the suspended matter sediment into the inclined tube, so that the sedimentation efficiency is reduced; in addition, part of water flow rises along the inclined pipe below the partition plate, takes away part of suspended matter sediments, and is discharged together with clear water, so that the precipitation effect is influenced.
Meanwhile, the flocculated particles in the sludge discharge channel are easy to return and can not keep a static water state in the sludge discharge channel, so that layering accelerated precipitation can not be formed, and the water flow state in the horizontal sedimentation pipe is influenced.
The existing horizontal sedimentation tube sedimentation technology still has the following problems: 1. the horizontal pipe is a rhombic pipe, the proportion of the effective settling area to the total water passing section is small, the vertical settling distances of all points in the section of the rhombic pipe are unequal, and the settling efficiency is influenced; 2. the sludge discharge channel is an inclined pipe inclined by 60 degrees, and the sludge discharge and sludge accumulation conditions in the sludge discharge channel are the same as those of a common inclined pipe sedimentation tank.
Therefore, the invention provides a horizontal flow vertical sludge discharge accelerated settling device.

Detailed Description
The technical scheme of the invention is more fully explained in detail by combining the attached drawings.
The concrete embodiment 1, a horizontal flow vertical sludge discharging accelerated deposition device, comprising a device body, a main frame of the device body comprises a vertical support 2 and a horizontal frame beam 1 positioned at the upper end and the lower end of the vertical support 2, a horizontal settling tube 3 and a sludge discharging channel 6 are arranged in the main frame, the lower part of the horizontal settling tube 6 has an inclination angle of 60 degrees, the sludge discharging channel 6 is arranged between the vertical edge at the right side of the horizontal settling tube 3 and the vertical support 2 at the right side, a concentration baffle plate 5 with an inclination angle of 75 degrees is arranged in the sludge discharging channel 2, the concentration baffle plate 5 is connected to the bottom of the inclined edge 4 of the horizontal settling tube, the concentration baffle plate 5 is arranged between the horizontal settling tube 3 and the sludge discharging, wherein, two vertical edges of the horizontal settling tube 3, the inclined edge 4 of the horizontal settling tube and the concentration plate 5 form a folded plate, the folded angles of two side edges of the folded plate are respectively 150 degrees and 165 degrees, and the device body is formed by horizontally installing a plurality of layers of folded plates.
The working principle is as follows: according to water flow direction 7, water flow flows through the horizontal settling tube 3 along the horizontal direction, flocculated particles in the water body settle on the inclined edge 4 of the lower part of the horizontal settling tube and slide down along the inclined edge 4 to enter the concentrated partition plate 5 in the vertical sludge discharge channel 6, settled particles are separated from settled water in the horizontal settling tube 3, settled water flows out along the horizontal direction of the horizontal settling tube 3, the concentration of the flocculated particles discharged into the sludge discharge channel 6 is increased vertically downwards, the flocculated particles sliding into the concentrated partition plate 5 under the action of the concentrated partition plate 5 are further adsorbed and concentrated with the settled flocculated particles in the vertical sludge discharge channel 6, the compactness is increased gradually, the flocculated body in the vertical sludge discharge channel 6 is precipitated downwards in an accelerating manner, the vertical sludge discharge channel 6 cannot be blocked, and the purposes of separating particles from thorough water and efficiently clarifying the water body are achieved.
The invention provides a horizontal flow vertical sludge discharge accelerated precipitation device, which has the advantages that:
the horizontal settling tube 3 is not blocked. Because the hypotenuse 4 of horizontal sedimentation pipe 3 is 60 degrees angles and the distance is shorter, the flocculation particle very fast slides in arranging mud passageway 6, can not block up horizontal sedimentation pipe 3.
And (II) the particles separated from the water cannot return again, water and mud can be separated separately, and mud and water are separated thoroughly. Because there is concentrated baffle 5 that the muddy water district kept apart in mud discharging channel 6, can prevent the flocculation particle in mud discharging channel 6 to return again, keep the interior static water state of mud discharging channel 6, the sediment is accelerated to the internal formation layering of mud discharging channel 6 for local water disturbance does not influence the water flow state in the horizontal sedimentation pipe 3 when the flocculation particle deposits in mud discharging channel 6.
The (III) concentration clapboard 5 has the functions of adsorption and concentration, and generates accelerated precipitation, so that the vertical sludge discharge channel 6 cannot be blocked. Because the water flow in the vertical sludge discharge channel 6 is in a static state, the concentration of the flocculated particles discharged from the top-down horizontal settling tube 3 is larger and larger, a layered accelerated settling state is formed under the action of the concentration partition plate 5, and the blockage of sludge can not be caused in the vertical sludge discharge channel 6.
And (IV) the precipitation efficiency is high, the liquid surface treatment load is large, and the advantages of low-temperature low-turbidity water and high-algae water treatment are more obvious.
And (V) the occupied area is small, the process improvement of the old sedimentation tank is facilitated, and the improvement of the water treatment quantity and the water quality of a water plant is more advantageous.
And sixthly, the effective sedimentation area is large, the installation is flexible, the device is suitable for different sedimentation tank depths, widths and lengths, and no triangular dead zone exists.
And (seventhly), the transportation, the storage and the installation are convenient, and the labor intensity of construction is low. The horizontal flow sedimentation system consists of three parts of independent elements, and the packaging, transportation and field storage are simple and convenient; the horizontal settling tube 3 and the vertical support 2 are connected in a plug-in mode by fasteners, and the installation is simple and convenient.
