Novel horizontal tube type sedimentation pond

Abstract

The invention relates to a novel horizontal tube type sedimentation pond. The novel horizontal tube type sedimentation pond comprises an upper precipitation separation device and a lower precipitation sludge discharging device, wherein the precipitation separation device comprises horizontal tube units and sludge chutes; each horizontal tube unit comprises an inclined plate, and a plurality of separating plates which are arranged at intervals on the lower side surface of each inclined plate; each separating plate is a V-shaped plate consisting of a surface A and a surface B, and an opening of the section of each V-shaped plate is toward the corresponding inclined plate; each surface A is arranged on the side surface of the corresponding inclined plate; all surfaces A are parallel to each other; the planes of the surfaces B are parallel to or intersected with the plane of the corresponding inclined plates; all surfaces B are parallel to each other; a sludge discharging opening is left between every two adjacent separating plates on the same inclined plate. The novel horizontal tube type sedimentation pond has the advantages that the horizontal tube units comprise the inclined plates and the separating plates, so that the convenience of processing, manufacturing and mounting is ensured; channels being narrow in upper part and wide in lower part can be formed by the sludge chutes between adjacent horizontal tube units, so that the distribution condition that more sludge is at the lower part of each sludge chute and less sludge is at the upper part of each sludge chute apply is adapted, and as a result, the high efficiency of the precipitation separation device can be ensured.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a novel horizontal tube sedimentation tank. Background technique [0002] At present, there are many types of sedimentation tanks on the market, such as advection sedimentation tanks, inclined plate sedimentation tanks, inclined tube sedimentation tanks, and labyrinth sedimentation tanks. , Horizontal sedimentation tank) have the following disadvantages: poor sedimentation effect, easy to cause reversible operation of suspended solids, low utilization rate of sedimentation tank, small water flow area, the above points restrict the sedimentation effect of the sedimentation device to a certain extent, so that Its clarification ability is greatly reduced. [0003] Patent No. 200610123752.2 mentions a horizontal tube sedimentation and separation device, which includes multiple sets of parallel sloping plates. Each set of parallel sloping plates is composed of an upper slo...

[0002] At present, there are many types of sedimentation tanks on the market, such as advection sedimentation tanks, inclined plate sedimentation tanks, inclined tube sedimentation tanks, and labyrinth sedimentation tanks. , Horizontal sedimentation tank) have the following disadvantages: poor sedimentation effect, easy to cause reversible operation of suspended solids, low utilization rate of sedimentation tank, small water flow area, the above points restrict the sedimentation effect of the sedimentation device to a certain extent, so that Its clarification ability is greatly reduced

Compared with the previous sedimentation tank, this horizontal tube sedimentation and separation device has been greatly improved, but it still has the following disadvantages: (1) The parallel inclined plates of each unit are composed of upper and lower inclined plates, and the partitions are arranged on two parallel inclined plates. Between the boards, it is extremely inconvenient to process, and the manufacturing difficulty and manufacturing cost are very high

(2) The upper and lower inclined plates are arranged in parallel, and a sludge slideway is formed between adjacent inclined plates. The sludge slideway is a slender channel with the same upper and lower width. This design is only suitable for relatively good water quality. In the occasions where the sludge concentration is high, the sedimentation effect will be very poor. This is because the upper layer of sludge slides down the sludge slide from top to bottom, and the bottom layer has the highest concentration of sludge, and the sludge accumulates At most, it has a great impact on the mud discharge effect of the bottom water flow channel

(3) The bottom of the sludge chute forms a sludge discharge window through reinforcing ribs. Since the upper layer of sludge continues to slide down from top to bottom, the bottom layer of sludge is very easy to accumulate. This situation not only affects the sewage in the bottom water flow channel The sedimentation effect of the mud has a greater impact, and to a certain extent affects the operation of the sludge slide
