Abstract
The utility model discloses a staggered arrangement system for cooling sectors of an indirect air cooling system. The staggered arrangement system comprises the indirect air cooling tower, a unit condenser I, a unit condenser II, a unit circulating water pump I and a unit circulating water pump II, wherein the indirect air cooling tower comprises a plurality of unit cooling sectors I and a plurality of unit cooling sectors II which are arranged along the circumference of the indirect air cooling tower at intervals in a staggered manner. The staggered arrangement system has the advantages that the influences of environmental wind on two units are basically identical; when loads of the units are identical, outlet water temperatures of cooling towers of the two units are identical, and operation backpressure of the cooling towers of the two units are identical; and simultaneously, the operation parameters of the units are stable.
Description
Technical field
The utility model relates to a kind of indirect dry cooling tower cooling sector arrangement system, particularly relates to a kind of indirect dry cooling tower and cools off sector interlaced arrangement system.
Background technology
The quality of indirect air cooling unit design is directly connected to the safe operation and the economic benefit of the back power plant of going into operation.There is certain influence in ambient wind to a cooling system, because the influence of strong wind, different wind direction and landform, make that to be looped around at the bottom of the air cooling tower air cooling tubes condenser radiating fin surrounding air changes in flow rate of circumference bigger, influence the heat transfer efficiency of air cooling tubes condenser, and then influence unit steam discharge back pressure, heat exchanging device performance and unit economy exert an influence, and special under the very big situation of ambient wind velocity, this influence is bigger.
At present, the indirect air cooling unit adopts two public air cooling towers of unit, recirculated water adopts the water system of unit system, and radiator is arranged outside tower, if the scheme that adopts every unit cooling sector half tower to arrange, when the public air cooling tower of two units, in unit running process, be subjected to the influence of ambient wind, windward side is different with the leaving water temperature of leeward side unit recirculated water, and then influencing the operation back pressure of two units, the corresponding unit of windward side radiator is good than leeward side unit operation situation.
The utility model content
The purpose of this utility model is to provide a kind of indirect dry cooling tower to cool off sector interlaced arrangement system.
The purpose of this utility model is implemented by following technical scheme, a kind of indirect dry cooling tower cools off sector interlaced arrangement system, it comprises indirect dry cooling tower, No. 1 unit condenser, No. 2 unit condensers, No. 1 unit water circulating pump and No. 2 unit water circulating pumps, described indirect dry cooling tower comprises several No. 1 unit cooling sector and several No. 2 unit cooling sectors, described No. 1 unit cooling sector and described No. 2 units cooling sector are arranged at interval along described indirect dry cooling tower circumference is staggered, the delivery port of No. 1 unit condenser is connected with the water inlet of described No. 1 unit cooling sector respectively by No. 1 unit water inlet pipe, and the water inlet of No. 1 unit water circulating pump is connected with the water return outlet of described No. 1 unit cooling sector respectively by No. 1 unit return pipe; The delivery port of No. 2 unit condensers is connected with the water inlet of described No. 2 units cooling sector respectively by No. 2 unit water inlet pipes, and the water inlet of No. 2 unit water circulating pumps is connected with the water return outlet of described No. 2 units cooling sector respectively by No. 2 unit return pipes.
Advantage of the present utility model is that ambient wind is basic identical to the influence of two units, two unit cooling tower leaving water temperatures and operation back pressure unanimity, unit operation parameter stability simultaneously.
