Description

technical field

The publication number is CN1278312 titled method and device for separating floating pollutants, used to clean open surfaces of liquids, especially methods and devices for recovering oil spills or other floating pollutants. Its core technology is to make the surface part of the water carrying pollutants flow over a skimming weir forming the inlet of the collection container, where the pollutants are separated from the water body and collected and treated separately.

The publication number is CN2392762, and the name is an automatic collection device for floating pollutants on the water surface, which mainly consists of a floating pipe, a one-way door, a mesh pedal and a mesh baffle. It is characterized in that: the inner sides of the two floating tubes are axially connected with one-way doors, the middle is overlapped with a mesh pedal, the two ends are respectively inserted with floating tubes, and the outer sides of the two floating tubes are connected with telescopic tubes, so that The two floating tubes after plugging are in the shape of "eight", and the bottom of each floating tube is connected with a mesh baffle in parallel.

The floating matter processor with the publication number CN2861278 is composed of a floating matter collection system, a conveyor belt system, a sewage suction system, an inclined plate sedimentation and mud discharge bed system, a support workbench guardrail component, a lifting device system and a hydrodynamic wheel system. The lifting rotary rod controls the lifting of the main conveyor belt system, the floating object collection system and the inclined plate sedimentation and mud discharge bed system. The power of the equipment adopts the combination of external power supply and hydraulic power. A hydrodynamic wheel device is installed on the wheel shaft.

Collection and transportation by salvage ships, this method is mainly used for manual collection and treatment by salvage ships when large-scale floating pollutants accumulate in the reservoir area. The basic principle is to use different fishing tools to fish the pollutants floating on the water surface into the hull, and then transport them from the hull to the garbage station for centralized treatment.

The above collection devices or methods have their own characteristics and strengths, but they do not match the characteristics of the leakage of floating pollutants in the water transfer channel, and cannot be well adapted to the characteristics of the water transfer channel. First of all, the leakage of floating liquid pollutants in long-distance water transfer channels is sudden and random. The collection device must meet the requirements in this regard and can be assembled and disassembled at any time; secondly, in view of the suddenness, the collection device must be portable. The structure is simple and the assembly is convenient.

It is required to collect floating pollutants at different water levels. Furthermore, the fluid in the distance water diversion channel has a certain flow velocity, and the erection of the collection device will cause water blocking and backwater problems. It is required that the collection device can solve the water blocking and backwater problems well without affecting the fluid flow flow rate, while reducing the impact of water flow on the collection device.

The current research on collecting floating pollutants by chemical methods is not mature enough, and the cost is too high.

The two sides are arc-shaped and shrink at the tail of the water collector, showing the characteristics of large water inlet opening and small tail shrinkage. The larger water inlet is conducive to expanding the collection width of standard monomers, and the narrower tail can reduce the internal space of the water collector and speed up mixing. Fluid flows down while reducing resistance to fluid and reducing backwater. The bottom surface below the water inlet 6 is funnel-like, the bottom surface faces the direction of fluid flow to form a water-facing surface, and the water-facing surface adopts a streamlined design.

Device 3. When the collection device is assembled, a side monomer 1 is installed at both ends, and the automatic servo water pumps 12 at both ends work at the same time to increase work efficiency.

The sealing connection between the standard monomers and between the standard monomers and the side monomers is connected by tooth grooves. Rubber gaskets are provided between the tooth grooves, and the connection is reinforced with bolts. Only the manifold 5 and the side body The confluence pipes 8 are connected with the confluence pipes 5, and the water collector 3 and the vertical flow pipe 4 work independently and do not participate in the connection.

A steel track 10 is fixedly installed on the water inlet wing wall or diversion pier of the control sluice of the water diversion channel, and a slide plate 11 that can move up and down freely is arranged in the track 10 . Sliding plate 11 tops are connected as a whole with the elevating rod on the hydraulic lifter 9, reserve the screw hole that is compatible with connecting screw rod in the sliding plate 11, make connecting screw rod can stretch into and bite. After the collection device is assembled from the standard unit 2 and the side unit 1, insert the telescopic connecting screw at both ends into the threaded hole in the track, and tighten it to fix it. The collection device is closely connected with the shore control system. The hydraulic lifting rod is operated through the hydraulic lifting system fixed on the shore, and both sides are operated simultaneously, so as to control the height of the collector from the water surface and meet the collection requirements of floating pollutants at different water levels.

The main function of the auxiliary system is to extract and store the collected floating pollutants. The working principle of the automatic servo water pump 12 is that when the water pressure reaches a specified value, the water pump is automatically turned on for pumping and drainage. The automatic servo water pump 12 is placed in the side unit pump pipe 7 of the collection device, and the suction pipe 13 is connected to the automatic servo water pump 12 and the bank. side storage tank 14 , whereby the floating pollutants are pumped into the storage tank 14 . The follow-up work is to focus on the relevant physical and chemical treatment of the floating pollutants in the storage pool 14 . In order to increase the collection speed of the collector, a set of auxiliary systems is symmetrically arranged on both sides of the river bank.

The single-width collection speed of the present invention (that is, the flow of floating pollutants and part of the water) is determined by the height of the collection device and the power of the automatic servo pump. When in use, automatic servo water pumps of different powers can be replaced according to the difference of water flow speed. Due to the streamlined design of the water collector of the collection device of the present invention, the resistance of floating pollutants to flow into the collection device can be reduced, water drop can be reduced, energy loss of the fluid can be reduced, backflow can be reduced, and the mixed fluid can enter the confluence at a faster speed.

The acquisition device adopts multiple standard monomers and two side monomers to assemble. The standard unit and side unit assembly are portable and convenient for transportation, assembly and disassembly; at the same time, different numbers of standard units can be assembled to adapt to water diversion channels of different widths.

A baffle is designed between the side monomer, the water collector and the shore. There will be gaps in the connecting section between the collection device and the control system. There is no water collector system in the gaps, and floating pollutants may leak downstream through the gaps at both ends. The baffle is used to guide the mixed fluid in the gap section to flow into the water collector to solve the problem of gap leakage.

The side monomer 1 is provided with a pump pipe 7 to store an automatic servo water pump 12 . The height of the pump pipe 7 is the same as that of the standard unit 2, and the automatic servo pump 12 is placed, which solves the problem of how to pump and discharge floating pollutants to the shore storage pool; the connecting rod set on the end of the pump pipe 7 solves the problem of connecting with the shore control system question.

Water collector 3 streamlined funnel-shaped design. In order to speed up the inflow speed of the mixed fluid, reduce the energy loss of the mixed fluid, avoid the backflow phenomenon caused by the water drop, and reduce the resistance of the water collector 3 to the fluid, a streamlined design is carried out on the water facing surface, and the water facing surface is concaved into a funnel shape. The two sides are arc-shaped and contracted at the tail of the water collector, the opening is large and the end is small. This design allows the mixed fluid of floating pollutants to flow into the water collector 3 normally, and the curved surface at the rear of the water collector 3 ends to make the floating pollutants mix and separate the fluid Faster downward entry into the vertical flow tube 4, while the cambered finish reduces fluid resistance.

The vertical flow pipe 4 and the confluence pipe 5 are arranged as flat oval pipes with a short minor axis. The flat oval tube has a smooth curve, which reduces the blocking effect on the fluid. At the same time, the length of the vertical flow tube is 400-900mm, which makes the water head of the water collector and the confluence pipe higher and increases the collection speed.

  During production and transportation, the single object is used as the object. When floating pollutant pollution occurs (bridge deck falls, dumps, leaks, dust or malicious human release, etc.), it should be assembled at the nearest control gate water inlet wing wall or diversion pier downstream of it. According to the width of the control gate of the long-distance water diversion channel, select the required number of standard monomers to assemble the collection device. At the same time, the control system is fixed on the shore and the auxiliary parts are prepared. Then the collection device is fixed on the slide plate in the track through the telescopic rod, and the self-weight of the collection device is used to control the hydraulic lifting rod at the same time, so that the collection device is lowered to near the liquid surface for collection. After collecting a certain amount of floating pollutants, the automatic servo pump starts to pump and discharge the floating pollutants to the shore storage pool. After the sudden floating pollutants are collected, the device is dismantled in turn, transported and kept for the next use. The pollutants in the storage pond are further treated.
