Description
?
Technical field
The present invention relates to the water treatment facilities technical field, be specifically related to a kind of recirculating cooling water system temperature control power-saving technique.
Background technology
Recirculating cooling water system is one of common public work of factory.The power consumption of recirculating cooling water system accounts for more than 30% of factory's public work power consumption usually.The administration of energy conservation of recirculating cooling water system directly influences the power cost of product.Yet, in a considerable amount of recirculating cooling water systems, lack the electricity consumption administration of energy conservation.Traditional recirculating cooling water system mainly is made up of circulating water pool, pump, the equipment that is cooled, cooling tower and pipeline etc.Its workflow is as follows: the cooling water that cooling tower gets off pressurizes through pump, delivers to the equipment of being cooled.Recirculated water is taken away the heat of equipment, gets back to cooling tower.Cooling tower is got back to circulating water pool after heated recirculated water is cooled off again.So circular flow, the continuous cooling requirement of the equipment of finishing.
At present, configuration pressure frequency-converting control device in recirculating cooling water system is also arranged.Its flow process is as follows: when the flow system flow demand changes, will cause the fluctuation of pressure.Pressure sensor passes to the pump variable frequency device with pressure change signal.Control the rotating speed of water pump, reach the purpose of economize on electricity.
There is following drawback in said system, in the conventional arrangement system, though pressure VFC loop is arranged, play the effect of control flow, certain energy-saving effect is arranged, but to system temperature, not control, when the equipment that is cooled produced heat decline or environment temperature reduction, recirculating cooling water system was taken away the ability of heat energy far above the demand of the equipment of being cooled, and causes the waste of electric power.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of recirculating cooling water system temperature control power-saving technique, the present invention efficiently solves traditional recirculating cooling water system and not only wastes electric power resource, the problem that causes enterprise's production cost to improve, and existing recirculating cooling water system poor work stability, the problem that fault rate is high have been solved.
The present invention is achieved through the following technical solutions:
A kind of recirculating cooling water system temperature control power-saving technique, system comprises cooling tower (1), circulating water pool (2), water pump (3), equipment (4) is cooled, and for cooling tower (1), circulating water pool (2), water pump (3), the pipeline (5) that the equipment (4) that is cooled is communicated with, pipeline (5) is provided with pressure sensor (6), pressure sensor (6) realizes that by data wire feedback is connected with water pump (3), it is characterized in that: the pipeline (5) between described cooling tower (1) and the equipment that is cooled (4) is provided with control valve (7), in the circulating water pool (2), or for the pipeline (5) before water pump (3) water inlet is provided with temperature sensor (8), temperature sensor (8) realizes that by data wire and control valve (7) feedback is connected.
The technical scheme that the present invention further solves is:
Described control valve (7) place pipeline (5) is provided with backwater bypass (9), backwater bypass (9) one ends are positioned on the pipeline (5) of control valve (7) water inlet, the other end is positioned on the pipeline (5) at control valve (7) delivery port place, and backwater bypass (9) is provided with bypass valve (10).
The present invention compared with prior art, has obvious advantage, the present invention sets up control valve, temperature sensor at traditional recirculating cooling water system, can regulate rotating speed of motor according to the cooling water water temperature in real time, thereby play energy-conservation effect, increase the backwater bypass simultaneously, thereby strengthen the stability of system works.
