Description

Prevent marine organism and strike and adnexed grid system

Technical Field

The invention relates to the field of water taking grids, in particular to a grid system for preventing marine organism impact and attachment.

Background

The seawater comprehensive utilization technology is widely used in China and all over the world, mainly comprises multiple aspects of seawater desalination, seawater cooling, seawater desulfurization, seawater recycling and the like, particularly in recent years, the construction projects of island engineering in petrochemical industry, electric power industry, nuclear power industry and the like are increased, and the importance of seawater as an island water source is increasingly remarkable. The comprehensive utilization of seawater has far-reaching significance for solving the problems of fresh water crisis, energy shortage and the like in social development.

The seawater intake is an important component of a seawater comprehensive utilization project, the marine environment is complex, the capital construction cost of the project such as required civil engineering installation is high, the risk is high, and the project is difficult to repair after failure, so the design technology of seawater intake needs to comprehensively consider the premise that the intake structure can normally operate for a long time, the construction cost is reasonable, the management and the maintenance are simple, and the marine environment is protected.

The water intake head is blocked and the water intake amount is reduced aiming at the corrosion problems caused by multi-directional water flow impact, biological attachment and blockage, biological impact and entrainment and biological attachment in the design of the seawater intake head, and the potential production hazard is formed by the reduction of the liquid levels of the diversion canal and the forebay due to the breeding of a large number of shellfish organisms such as barnacles, red seas and the like. For large-scale seawater taking facilities, such as chemical industry, electric power industry and nuclear power industry, the water consumption is small, namely tens of thousands of tons/hour, and more than tens of thousands of tons/hour, the design of the water taking head is more important, and once the water taking is abnormal, the water taking safety is seriously influenced. The water intake of so biggest can only arrange dive inspection, clearance operation when stopping, and the cost is huge to the enterprise, is unable to stop the fortune at all under most production conditions moreover, and manual work also has very high potential safety hazard under water. The on-line remote inspection is not stopped, and the flow rate is high due to huge water amount, so that the automatic equipment is difficult to approach and observe, and the cleaning operation is difficult to realize.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The invention is implemented in detail, the grid system for preventing marine organism impact and attachment comprises a grid system, wherein the grid system comprises a dosing line camera sleeve 1, air-water disturbance sleeves 2 are mounted at two ends of the dosing line camera sleeve 1, an air-water medium pipeline 3 is mounted at the bottom of the air-water disturbance sleeve 2, a dosing medium pipeline 4 and a camera data power line 5 are connected to the middle of the dosing line camera sleeve 1 at the bottom, a medicament injection port 6 and a camera opening 7 are arranged on the dosing line camera sleeve 1 in an array mode, and air-water orbiting injection ports 8 are distributed on the air-water disturbance sleeve 2 at equal intervals.

As an improvement, pipelines of the medicament adding module, the camera monitoring module, the water pump and the air compressor are fixed in a water taking pipe duct 10, a water taking head 9 is installed at the tail end of the water taking pipe duct 10, and a grating is installed on the water taking head 9.

The working principle of the invention is as follows: in order to solve the existing problems, the invention discloses a novel water taking head grille which utilizes the integral form of the original grille to increase steam-water mixing turbulence, dosing scattering nozzles and remote monitoring camera shooting. A matched medicine adding facility, an air compressor, a pressurized water pump and a matched conveying pipeline.

At present, two types of common grid forms are designed in combination with a water intake, one type is a cylindrical grid matched with a mushroom head type, and the other type is a common rectangular section grid, wherein the rectangular section grid is more widely applied and is also more suitable for large water taking facilities.

For the cylindrical grating, the original grating laths with edges perpendicular to the water flow direction and right and left directions are reformed, and the grating lath type structure is changed into a tubular structure. The forward pipe in the direction perpendicular to the water flow is used as a dosing sleeve and a pinhole camera sleeve, and a hole is formed in the position of the axis opposite to the water flow to be used as a dosing nozzle and a camera mounting hole, so that the all-dimensional dosing of the water taking head can be realized; the two lateral grating laths are also transformed into a tubular structure, are used as a gas-water mixed disturbance tube or a sleeve, and are provided with holes on the side of opposite axial lines so as to realize the effect of gas-water disturbance and prevent the impact and the attachment of marine organisms, and meanwhile, the holes are not intercepted.

For the rectangular grating, the original peripheral frame is improved. The frame right above and below can be tubular or columnar hollow structure. A frame below the frame is used as a dosing sleeve, and a hole is formed in the axis of the upper surface of the frame to be used as a dosing nozzle mounting hole; the position of the frame right above is used as a camera sleeve, and a hole is formed in the axis of the lower surface of the frame. The vertical frames on the two sides are also transformed into a tubular or columnar hollow structure, are used as a gas-liquid mixing turbulence sleeve, and are provided with holes on the opposite axial sides to realize the action of gas-water disturbance and splashing and block marine organisms from attaching to the grating. When the area of the grating plate is large, the grating plate can be assembled in a manner that all medium pipelines are arranged in a crossed manner on the premise of meeting the structural design requirement.

Each sleeve design extends to the interface of the water intake header and the water intake conduit to facilitate connection of the various media conduits and communication lines. Considering the requirement of seawater operation environment, the material of the pipeline is consistent with that of the grating, and the welding seams are required to adopt a heat treatment process to eliminate the influence of galvanic corrosion. The distance between the grids is within the allowable range of the design requirement, and the grids are designed according to the upper limit on the condition that the flow rate of the inlet water is not influenced. The vertical surfaces of the grids are designed by arcs, so that the possibility of marine organism attachment is further reduced.
