Background technology
At present, in HVDC transmission system, outer cooling water system is as the important composition of converter valve cooling system, and its ruuning situation directly influences whole straight-flow system ability to transmit electricity. It is particularly important thus it is guaranteed that outer cooling water system stably, functions reliably and efficiently runs. And in today of scarcity of fresh water resources, sea water replaces fresh water as industrial cooling water, it it is one of important channel of freshwater resources crises problem solving China coast city and area. Additionally, most DC converter station often islet operations, freshwater resources are more deficient, limit the popularization construction of DC converter station.
Existing outer cooling water system there is problems in that the outer cold scheme routine of (1) valve adopts cooling system of fresh water, and it is relatively big that it has the supply water yield, and compares, compared with salt water cooling system, the shortcoming that cooling effectiveness is relatively low; (2) its outer cooling system of cooling system of fresh water comprises a large amount of structures and equipment, such as closed cooling tower, spray pond, feeding spraying pump etc., if water source of fresh water is it cannot be guaranteed that two-way supplies water, the bulky industrial makeup Water System being available for three days supply water yields of converter valve supporting must also be set, namely industrial pond is set, the attached constructions of structures such as industry pump house, take up an area big and operation maintenance are more complicated. (3) for the current conversion station of islet operation, periphery water supply network is unsound even to be lacked, and water source of fresh water is extremely valuable, adopts the mode of conventional municipal pipe network diversion, must increase water supply network construction and put into, the cost of current conversion station cooling system will be greatly improved.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of valve external condensation system adopting cooled with seawater, its effectively save freshwater resources of energy, and cooling effect is better.
For achieving the above object, the present invention takes techniques below scheme: a kind of valve external condensation system adopting cooled with seawater, it is characterised in that: it includes former water water intake system, heat-exchange system, circulation and converter valve;Sea water is caused in described converter valve and stores as heat exchange medium by described former water water intake system; Heat exchange medium in described converter valve and sea water are carried out heat exchange by described heat-exchange system; Described circulation is by seawater circulation transmission to described converter valve and heat-exchange system; Described former water water intake system includes raw water pump, sea water transfer pipeline, filter tank and pond; Described sea water transfer pipeline one end is arranged on sea, and the other end is connected with described filter tank entrance point through described raw water pump, and the described filter tank port of export is connected with the import of described pond through described sea water transfer pipeline, and the sea water after filtration is stored in described pond.
Described circulation includes outer cold main circulation pump and full-automatic filter; Described basin outlet connects described full-automatic filter through sea water transfer pipeline, and is provided with described outer cold main circulation pump on the described sea water transfer pipeline between described pond and described full-automatic filter.

Due to the fact that and take above technical scheme, it has the advantage that 1, the present invention can reach the purpose of effectively save freshwater resources, and there is deep-sea water intaking temperature be low, good cooling results and the simple advantage of system operational management, the area lacked for coastal cities and water resource is particularly important. 2, the heat exchanger of the present invention adopts plate type heat exchanger, and outer cold main circulation pump, pond, filter tank etc. all can indoor be arranged, floor space is little, and relative to the closed cooling tower that freshwater system adopts, the basic noiselessness of plate type heat exchanger, more environmental protection. 3, owing to the water withdrawal of sea water service system is only the 5% of water consumption, and the freshwater system minimizing more than 95% that its displacement is more traditional, Seawater Cooling Treatment Technology is in various fields extensive uses such as China's industry each petrochemical industry, iron and steel, thermal power plants, big for solving the water for industrial use water yield, and the problem such as shortage of fresh water is significant.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As it is shown in figure 1, the present invention provides a kind of valve external condensation system adopting cooled with seawater, it includes former water water intake system, heat-exchange system, circulation and converter valve 1. Sea water is caused and stores as heat exchange medium in converter valve 1 by former water water intake system; Heat exchange medium in converter valve 1 and sea water are carried out heat exchange by heat-exchange system, to reach to cool down heat exchange medium, and then lower the temperature heat exchange for converter valve 1; Circulation is by seawater circulation transmission to converter valve 1 and heat-exchange system.
Wherein, former water water intake system includes raw water pump 2, sea water transfer pipeline, filter tank 3 and pond 4. Sea water transfer pipeline one end is arranged on sea, and the other end is connected with filter tank 3 entrance point through raw water pump 2. Filter tank 3 port of export is connected with pond 4 import through sea water transfer pipeline, and the sea water after filtration is stored in pond 4.
In above-described embodiment, circulation includes outer cold main circulation pump 6 and full-automatic filter 5.Pond 4 exports and connects full-automatic filter 5 through sea water transfer pipeline, and is provided with outer cold main circulation pump 6 on the sea water transfer pipeline between pond 4 and full-automatic filter 5.
