Abstract
The utility model discloses an energy-saving cold and hot water circulating system and solves the problem of high idle work consumption of an existing cold and hot water circulating system. The energy-saving cold and hot water circulating system comprises a hot water pond and a cold water tower, wherein a water inlet pipe is connected to a water inlet of the hot water pond; a water outlet of the hot water pond is connected with a water inlet of the cold water tower through a circulating water pipe; a hot water pump is arranged on the circulating water pipe; a plurality of rotary spray nozzles which are communicated with the circulating water pipe are uniformly arranged in the inner middle of the cold water tower; a water outlet pipe is connected to a water outlet of the cold water tower; a centrifugal pump is arranged on the water outlet pipe and is positioned below the cold water tower; the effective vertical distance between the centrifugal pump and the cold water tower is 6m; the diameter of an impeller of the centrifugal pump is 260mm. The energy-saving cold and hot water circulating system is simple in structure and reasonable in design, minimizes the idle work consumption in an operation process, has a quite remarkable power-saving effect and meets national energy-saving requirements; the fall of single-pump operation current reaches 10A, and the aims of saving the cost and improving the benefits are achieved.
Description
Technical field
The utility model relates to chemical production technical field, specifically a kind of energy-saving cold hot water cyclesystem.
Background technology
In chemical process, the general cooling problem of hot water needs producing of producing that all can relate to, the hot water-cooled system of existing processing all has some problems, as: chemical pump type selection and the process conditions situation problem such as do not want to match in the defect of the structural design of system own, system, make system in the situation that meeting production load, also produce a large amount of useless power consumption, occur the situation of low load with strong power, thereby cause energy waste more serious.
Summary of the invention
The purpose of this utility model is to exist useless power consumption to waste serious problem in order to solve the hot water-cooled system of existing processing, and a kind of energy-saving cold hot water cyclesystem is provided.
The utility model is achieved through the following technical solutions:
An energy-saving cold hot water cyclesystem, comprises hot-tub and cooling tower, on the water inlet of hot-tub, is connected to water inlet pipe, and the delivery port of hot-tub is connected by circulating water pipe with the water inlet of cooling tower, and heat-exchanger pump is installed on circulating water pipe; The centre position of cooling tower inside is uniform is provided with some rotary nozzles that communicate with circulating water pipe, the delivery port of cooling tower is connected to outlet pipe, centrifugal pump is installed on outlet pipe, centrifugal pump is positioned at cooling tower below, centrifugal pump is 6m to effective vertical range of cooling tower, and the diameter of the impeller of centrifugal pump is 260mm.
In chemical process, the hot water producing when certain production workshop section produces can be drained into by the water inlet pipe on hot-tub in hot-tub, circulating water pipe is evacuated to the hot water in hot-tub in cooling tower by heat-exchanger pump, hot water sprays by the rotary nozzle in cooling tower the processing of lowering the temperature, water after cooling is centrifuged pump by the outlet pipe on cooling tower and returns in production workshop section again, with this, repeatedly carry out, reach the object of circulation temperature lowering.
Centrifugal pump in the utility model forms through test transformation repeatedly, general centrifugal pump be configured to 200m
3/ h, lift 32m, power 30kW, impeller diameter is 330mm, normal electric current 40A in service.The vavuum pump that effective object of the present utility model adopts needs internal circulating load approximately 150 m
3/ h, add cooling tower potential difference, need lift 15m enough, through test several times, transform: 1) transform for the first time and transform the impeller original diameter 330mm of centrifugal pump as 310mm, install rear unlatching normal operation, electric current is 37A, and outlet of centrifugal pump valve opening degree is constant on former basis, moves class's current stabilization; 2) transform for the second time the impeller diameter 310mm of centrifugal pump is continued to transform as 280mm, install rear unlatching normal operation, electric current is 34A, pump discharge valve opening degree than originally many two circles, move one day electric current, discharge is all stable; 3) transform for the third time the impeller diameter 280mm of centrifugal pump is continued to transform as 260mm, install rear unlatching normal operation, electric current drops to 30A, and outlet of centrifugal pump valve open degree on transformation operation basis is for the second time constant, pressure, flow foot can guarantee the normal production and application of effective object of the present utility model (production workshop section) vavuum pump.Finally, the impeller diameter of centrifugal pump is controlled and is decreased to 260mm, thereby make the useless power consumption of the utility model system be down to minimum.
The utility model is simple in structure, reasonable in design, and this system is down to the useless power consumption in running minimum, power savings highly significant, and single pump operation electric current declines and reaches 10A, has reached object cost-saving, that increase the benefit, meets national energy-saving requirement.
