Embodiment 1

[0036] The jet gravity flow sedimentation device of the present invention consists of the outer body of the sedimentation device, the flow partition, the jet impact coagulator, the flocculation zone, the sedimentation zone, the reinforcement grid, the sewage outlet, the sump, and the liquid discharge The water flow direction of the jet impact coagulator is the same as that of the water inlet. The outlet of the jet impact coagulator is located on the upper part of the sedimentation device to provide efficient mixing and coagulation effects. One end of the flow baffle is sealed to the outer body of the sedimentation device. The other end forms a water flow channel. The staggered arrangement between the two adjacent flow partitions divides the inside of the sedimentation device into an S-shaped water flow channel connected end to end. One end of the water flow channel is connected to the water inlet, and the other end is connected to the sump and the outlet. The liquid port is conn...

Embodiment 2

[0040] According to the spray type gravity flow type coagulation and sedimentation device, according to the processing volume and viscosity of the liquid to be processed, the structure of the sedimentation device is confirmed, the trough-shaped structure sedimentation device is adopted for small-scale processing volume, and the adoption of small-scale processing volume Square structure sedimentation device, round structure sedimentation device for medium and large-scale processing capacity.

[0041] The corresponding materials are selected according to the nature of the liquid to be treated. The drinking water purification treatment uses stainless steel such as 316L / 316 / 304, the sewage purification treatment uses ordinary steel plate production and anti-corrosion treatment, and the alcohol purification treatment uses 316L / 316 / 304 And other stainless steel production.

[0042] After the precipitation device structure, materials, and purification capacity are determined, parameters a...

[0046] Drinking water pretreatment

[0047] For example, in drinking water treatment, to provide source water with turbidity within 10NTU after pretreatment for ultrafiltration: first, confirm whether to use 304, or 316L or 316 metal materials, sanitary PE, PVC_U and other non-metals according to the water treatment. Material; According to the turbidity of the source water, such as 600NTU and the treatment target effluent 10NTU, the overall treatment time is determined to be 19 minutes; the third step, the combined treatment total flow is set as <1000t / d, to confirm the structure of the device, such as the use of a square three-flow structure, no spray type coagulant dosing device; Step 4, confirm the overall size of the device, separation size, external pipe size, sewage outlet structure, Quantity and external dimensions, size of jet impact coagulator; step 5, general drawing, single or part drawing, support drawing, firmware drawing, etc.; step 6, after the individual parts are ...

Abstract

A jet type gravity backflow type precipitation device is used for separation and purification of impurities in water and other low-viscosity liquids in a flowing process; with use of a shock coagulation technology, flocculation, agglutination and precipitation of suspended matters are accelerated, the water or the low-viscosity liquids are flowed back for multiple times under separation and constraint in the device under gravity, and S-shaped water flow channels connected from head to tail are formed; a plurality of precipitation zones are formed at the bottom, a plurality of flocculation zones are formed at the upper part, multi-level agglutination and precipitation is formed, and an efficient purification effect is achieved; at the same time, with use of a characteristic that the impurity density is higher than the density of the liquids, the impurities in the low-viscosity liquids are naturally submerged due to the gravity action in the multiple backflow process in a vertical direction to achieve separation and purification; the device is a key technology for production and living water, drinking water and sewage treatment, and has the special effects on purification treatment on high-impurity-content liquids, namely high-turbidity source water.

Description

Technical field [0001] The invention is used for the separation and purification of impurities in low-viscosity liquids such as water during the flow process, mainly including but not limited to water treatment such as industrial and agricultural water supply and drainage, municipal water supply and drainage, and the purification of wine, beverages, oils and other fields. , Domestic water treatment and sewage treatment. Background technique [0002] Traditional coagulation and sedimentation devices and facilities are mainly used in urban waterworks and sewage treatment plants, and separate mixing and flocculation. Each separated area has a single function and low sedimentation efficiency. Most of them are constructed with concrete and occupy a large area. The flow direction and sedimentation cycle is long (mostly 60-120 minutes in water plants), the space utilization is low, maintenance is difficult, and the cost is high. [0003] At present, some new types of equipment have appea...
