Abstract
An arrangement structure of a gas turbine power plant circulating water pump station comprises a mechanical draft cooling tower and a circulating water pump. The mechanical draft cooling tower and a cooling tower water tank are elevated to the ground. The circulating water pump is arranged nearby in the open air on the ground near the cooling tower water tank, is directly connected with the cooling tower water tank and sucks water from the cooling tower water tank. A suction well is disposed at a suction hole of the circulating water pump and disposed in the cooling tower water tank. The circulating water pump is a horizontal single-stage double-suction centrifugal pump in a horizontal split structure. A flat-plate filter screen used for filtering impurity is disposed in front of the suction wheel of the circulating water pump. An electric hoist meeting the needs of the flat-plate filter screen for washing and maintenance during operating is disposed on the upper portion of the flat-plate filter screen. The arrangement structure has the advantages that a system is greatly simplified; investment and floor area are saved; compared to vertical diagonal flow pumps, the circulating water pump which is the horizontal split centrifugal pump is higher in reliability, more convenient to maintain, and low in manufacture cost.

Technical field
What the present invention relates to is to adopt mechanical-draft cooling tower to carry out the arrangement of the dynamo-electric factory of the cooling combustion of secondary cycle circulating pump room.
Background technology
Deposits in Eastern Coastal China economic development is at present rapid, and power demand is large, the requirement improving in order to meet this area economic development and people's living standard, and country often needs every year to drop into huge fund and is used for building power plant.The abbreviation that fires dynamo-electric Chang Wei gas-turbine electric power plant is a kind of clean power technology.The fuel that fires dynamo-electric factory is natural gas, fuel oil or industrial associated gas etc., and because burning is complete, emission that its burning generates is few to ambient influnence, and noise pollution is little; And fire that dynamo-electric factory has that installation piece, volume are little, reduced investment, the advantage such as efficiency is high, running cost is low and life cycle is long, the dynamo-electric factory of state's internal combustion project development is built more at present.
For adopting mechanical-draft cooling tower to carry out the dynamo-electric factory of the cooling combustion of secondary cycle, generally need near cooling tower, build a semi-underground type circulating pump room, in following pump house, arrange the equipment such as circulating water pump, filter screen, gate, driving, circulating water pump pattern can adopt centrifugal pump of horizontal axis or vertical diagonal flow pump.The general dark 2 meters of left and right of pond of cooling tower, be arranged in below ground, recirculated cooling water is undertaken falling within pond under caloic exchange afterwards by regions such as packings, then by dark culvert or open channel, from flowing to, follow pump house, after the impurity in filter screen equipment filtering recirculated water, by circulating water pump, boost to condenser and re-start circulation.
For fear of circulating pump room, the air intake of mechanical-draft cooling tower is had a negative impact, total plain cloth is set up General Requirements mechanical-draft cooling tower and leaves other building more than 15 meters, and this has increased floor space and investment to a certain extent.Fire dynamo-electric factory due to the reasons such as needs heat supply (electricity) be generally positioned at industrial park or near urban district to approach load center as far as possible, along with expanding economy, the land used index in these regions is also more and more nervous.Therefore, optimize and improve the arrangement form of traditional recirculating cooling water system, have great importance.
Summary of the invention
The object of the invention is to overcome the deficiency of the dynamo-electric factory of existing combustion circulating pump room arrangement, a kind of employing pond of cooling tower ground type layout, the outdoor layout in circulating water pump ground are provided, when reducing initial investment and project occupation of land, can guarantee the arrangement of the dynamo-electric factory of the combustion circulating pump room of system reliability.
The object of the invention is to complete by following technical solution, it comprises mechanical-draft cooling tower and circulating water pump, and described mechanical-draft cooling tower and pond of cooling tower integral raising are to ground configuration; Described circulating water pump is nearby near the outdoor ground being arranged in pond of cooling tower, is directly connected with pond of cooling tower and from wherein absorbing water; Water sucking mouth at circulating water pump is provided with absorbing well, absorption well, and this absorbing well, absorption well is placed in described pond of cooling tower.
The horizontal single-stage double suction centrifugal pump of opening structure pattern in described circulating water pump employing level, arranges one for the plate filter screen of impurity screening before the absorbing well, absorption well of circulating water pump; On the top of described plate filter screen, be provided with and meet the electric block that needs were rinsed, overhauled in plate filter screen lifting in service.
The preferred technical scheme of the present invention is: described mechanical-draft cooling tower disposes 6 altogether, and the amount of cooling water of every mechanical-draft cooling tower is 3200m
3/ h; Dispose 4 outdoor horizontal circulating water pump; 6 described mechanical-draft cooling towers are arranged on same straight line, and every 3 mechanical-draft cooling towers are one group, and 4-6 meters of the spacing between two groups of mechanical-draft cooling towers are preferably 5 meters.
Compared with prior art, advantage of the present invention is: more than the pond of cooling tower that is generally arranged in below ground is raised to ground, and cancelled traditional dark culvert of recirculated water artesian diversion or open channel, cancelled the underground and superstructure of traditional circulating pump room, circulating water pump is outdoor being arranged near the ground of pond of cooling tower nearby, directly from pond of cooling tower water suction, thereby greatly simplified system, saved investment and taken up an area.In addition, open, centrifugal pump of horizontal axis in circulating water pump pattern employing level, compare with adopting vertical diagonal flow pump, reliability is higher, repair and maintenance is more convenient, and cost is also lower.
Accompanying drawing explanation
Fig. 1 is structural configuration schematic diagram of the present invention.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further introduced: shown in Fig. 1,2, the arrangement of the dynamo-electric factory of combustion of the present invention circulating pump room, it comprises mechanical-draft cooling tower 1 and circulating water pump 2, and described mechanical-draft cooling tower 1 and pond of cooling tower 3 integral raisings of configuration are to ground configuration; Described circulating water pump 2 is nearby near the outdoor ground being arranged in pond of cooling tower 3, is directly connected with pond of cooling tower 3 and from wherein absorbing water; In the water sucking mouth of circulating water pump 2, be provided with absorbing well, absorption well 4, and this absorbing well, absorption well 4 is placed in described pond of cooling tower 3.
The horizontal single-stage double suction centrifugal pump of opening structure pattern in described circulating water pump 2 employing levels, one plate filter screen for impurity screening of the front setting of absorbing well, absorption well 4 of circulating water pump 2; On the top of described plate filter screen, be provided with and meet the electric block that needs were rinsed, overhauled in plate filter screen lifting in service.
