Abstract
The utility model discloses a circulating water replenishing mode modification device, which relates to the field of circulating water cooling equipment. The circulating water replenishing mode modification device comprises a circulating water forebay and a circulating pump, wherein the circulating water forebay is communicated with the circulating pump through a pipeline; and a water inlet of the circulating water forebay is communicated with a water replenishing pipe. By implementing the technical scheme provided by the utility model, circulating water with lower temperature is directly replenished into the circulating water forebay and led into the circulating pump; under a condition of certain environmental temperature, the inlet temperature of the circulating water can be obviously reduced particularly when the temperature is high, so that the heat exchange performance of a cooling tower is improved, the vacuum degree of a steam turbine generator condenser is obviously improved under a full load operation condition, and the device has obvious coal saving and water saving benefits.
Description
Technical field
The utility model belongs to the circulating water apparatus field, is a kind of circulating cooling make-up water mode device for modifying specifically.
Background technology
The energy and water resource are the essential condition that the mankind depend on for existence and development, and energy savings is a fundamental state policy of China.Thermal power plant is an industry that constantly primary energy is converted into secondary energy sources, is the rich and influential family who consumes primary energy, is therefore improving awareness of saving energy, strengthens the energy conservation aspect, and tool is of great significance.In the thermodynamic cycle of modern large-scale power station condensing steam turbine generator group, condenser is the core heat transmission equipment of s cold end system, its main task is turbine discharge is condensed into water and set up and keep certain vacuum at the turbine discharge mouth, and vacuum is the leading indicator that characterizes condenser work, is one of principal element that affects the steam turbine economical operation.The vacuum reduction can make the steam consumption of steam turbine and coal consumption increase, and affect the security with unit equipment of exerting oneself of steam turbine.One of principal element that affects Steam Turbine Condenser Vacuum is the cooling-tower circulating water inlet temperature to reduce the tightness that Inlet Temperature of Circulating Water can improve the unit vacuum system greatly.Under the certain condition of environment temperature, especially higher time of temperature, the circulating cooling make-up water water temperature is often lower than cooling water backwater water temperature, and present water supplementing method is that circulating cooling make-up water is mended the recirculated water after-bay, then flow in circulating pump through circulating water front pond, summer, vacuum was low because the temperature height can cause circulating water temperature high, and the unit specific steam consumption is high.Therefore how to reduce Inlet Temperature of Circulating Water, improving condenser vacuum is a problem demanding prompt solution.
The utility model content
The technical problems to be solved in the utility model is: a kind of circulating cooling make-up water mode device for modifying is provided, can overcomes the high shortcoming of Inlet Temperature of Circulating Water in existing water supplementing method.
To achieve these goals, the technical solution adopted in the utility model is: a kind of circulating cooling make-up water mode device for modifying, comprise circulating water front pond and circulating pump, circulating water front pond and circulating pump be by pipeline communication, is communicated with filling pipe at the water inlet of circulating water front pond.
On described filling pipe, hand-operated valve is installed.
The beneficial effect that the utility model brings is: by the enforcement of technical solutions of the utility model, the circulating cooling make-up water that temperature is lower is directly mended circulating water front pond, introduce circulating pump, under the certain condition of environment temperature, when especially temperature is higher, can obviously reduce Inlet Temperature of Circulating Water, improve the heat exchange property of cooling tower, oepration at full load situation tubine condenser vacuum is significantly improved, and has and economizes on coal significantly and water-saving benefit.
Description of drawings
Fig. 1 is the structural representation that the circulating cooling make-up water mode is transformed front device;
Fig. 2 is the structural representation of circulating cooling make-up water mode device for modifying.
Mark in figure: 1, recirculated water after-bay, 2, circulating water front pond, 3, circulating pump, 4, filling pipe, 5, hand-operated valve.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 2, a kind of circulating cooling make-up water mode device for modifying comprises circulating water front pond 2 and circulating pump 3, and circulating water front pond 2 by pipeline communication, is communicated with filling pipe 4 at the water inlet of circulating water front pond 2 with circulating pump 3; On described filling pipe 4, hand-operated valve 5 is installed.
The utility model is when carrying out moisturizing, the circulating cooling make-up water that temperature is lower flows directly into the filling pipe 4 of new clothes from water supplement port, rather than recirculated water after-bay 1 as shown in Figure 1, filled into respectively the circulating water front pond 2 of two Steam Turbine by filling pipe 4, and enter in circulating pump 3.Hand-operated valve 5 is installed on filling pipe 4 can be controlled rate of water make-up.
Claims (2)
1. a circulating cooling make-up water mode device for modifying, comprise circulating water front pond (2) and circulating pump (3), and by pipeline communication, it is characterized in that: the water inlet at circulating water front pond (2) is communicated with filling pipe (4) to circulating water front pond (2) with circulating pump (3).
2. a kind of circulating cooling make-up water mode device for modifying according to claim 1, is characterized in that: hand-operated valve (5) is installed on described filling pipe (4).
