Description
Technical field
The invention belongs to cooling circulating water transportation art, more particularly to a kind of energy-conservation cooling circulating water for automatically adjusting temperature
Device.
Background technology
At present, in the production of the industries such as oil, chemical industry, electric power, a set of cooling circulating water device is generally multiple productions
Workshop or multigroup heat-exchanger rig cooling water supply, form a plurality of cooling branch road in parallel, it is necessary to manual adjustment water circulating pump outlet valve
Door or pipe valve are to meet the temperature requirement of every cooling circuit.Due to the heat exchange power and pepeline characteristic of every cooling circuit
It is different, it is also different to the temperature requirement of cooling water or cooled raw material, therefore traffic demand is also different.If only adjusting water
Pump discharge valve or main line valve, to meet the cooling branch road requirement that operating mode is worst, necessarily cause part cooling circuit flow
It is excessive, waste electric energy；If adjusting branch line valve, multiple branch circuit is manually cumbersome, waste of manpower resource, while can not be accurate
Really control temperature, it is impossible to the purpose of maximum energy-conservation is realized using the area requirement of temperature.
The content of the invention
Technical problem：In order to solve the defect of prior art, the invention provides a kind of energy-saving cold for automatically adjusting temperature
But circulating water device, to solve the energy and human resources that Flow-rate adjustment is caused during many cooling branch circuit parallel connections in existing sorts of systems
Waste.
Technical scheme：A kind of energy-conservation cooling circulating water device for automatically adjusting temperature that the present invention is provided, including connect successively
It is connected into the cooling tower of ring, circulating water pool, one group of outlet pipeline, one group of cooling circuit for being arranged in parallel for being arranged in parallel；It is described go out
Water circulating pump, check-valves, gate valve are sequentially provided with water lines；Intelligent temperature regulating valve is sequentially provided with the cooling circuit, is changed
Thermal, heat-exchanger rig outlet gate valve, the heat-exchanger rig include circulating water line and material pipeline, the intelligent temperature regulation
Valve, the circulating water line of heat-exchanger rig, heat-exchanger rig outlet gate valve are sequentially connected, and are become at the material tube outlet provided with temperature
Send device.
As an improvement, the quantity of the cooling circuit is more than two.
Improved as another, intelligent temperature regulating valve 6 is the dynamoelectric proportion valve of PID control.
As a further improvement, the intelligent temperature regulating valve is the dynamoelectric proportion valve with PID controller, the temperature becomes
Send device output detection signal to the PID controller of intelligent temperature regulating valve, the PID controller outputs control signals to electronic ratio
Example valve.
Beneficial effect：The energy-conservation cooling circulating water device for temperature that what the present invention was provided automatically adjust effectively realizes cooling and followed
The Intelligent adjustment of ring water system, has reached energy-saving run and has saved the purpose of human resources.
Brief description of the drawings
Fig. 1 is the structural representation for the energy-conservation cooling circulating water device for automatically adjusting temperature.
Embodiment
Invention is further illustrated below in conjunction with the accompanying drawings.
The energy-conservation cooling circulating water device of temperature is automatically adjusted, Fig. 1 is seen, including be sequentially connected the cooling tower 1 of cyclization, circulation
Pond 2, one group of outlet pipeline 3, one group of cooling circuit 4 for being arranged in parallel for being arranged in parallel；Circulation is sequentially provided with outlet pipeline 3
Water pump 31, check-valves 32, gate valve 33；Cooling circuit 4 goes out provided with intelligent temperature regulating valve 41, heat-exchanger rig 42, heat-exchanger rig
Mouth gate valve 43, heat-exchanger rig 42 includes circulating water line and material pipeline, intelligent temperature regulating valve 41, the circulation of heat-exchanger rig 42
Water lines, heat-exchanger rig outlet gate valve 43 are sequentially connected, and temperature transmitter 44 is provided with material tube outlet.Cooling circuit 4
Quantity is more than two.Intelligent temperature regulating valve 6 is dynamoelectric proportion valve.
In the device, the generally multi-purpose standby configuration of water circulating pump 31, pump discharge, which installs check-valves 32, prevents water hammer
Destruction to water circulating pump 31, gate valve 33 is used as service valve, without Flow-rate adjustment, when circulation is normally run
It is fully open.The quantity of cooling circuit 4 is two more parallels, and the cooling requirement of every cooling circuit 4 is different.
The operation principle of the device is：Cooling circulating water in circulating water pool 2 is separately flowed into outlet pipeline 3, through intelligence
Temperature control valve (TCV) 41 simultaneously respectively enters cooling circuit 4 after collecting, and hot friendship is carried out with the material in the material pipeline of heat-exchanger rig 42
Change, then cooling tower 1 is returned to through gate valve 33, the wherein aperture in normal operation of gate valve 33 is 100%.
Material cooling effect is by temperature transmitter 44 and the synergic adjustment of intelligent temperature regulating valve 41：Adjusted by intelligent temperature
Valve 41 presets material chilling temperature, the temperature of charge of the material tube outlet of the monitoring heat-exchanger rig 42 of temperature transmitter 44；Intelligence
Temperature control valve (TCV) 41 is the dynamoelectric proportion valve with PID controller, and the output of temperature transmitter 44 detection signal to intelligent temperature is adjusted
The PID controller of valve 41, PID controller outputs control signals to dynamoelectric proportion valve, the cooling water flow in pipeline just may be used
To cool down material to design temperature.The temperature of every cooling circuit 4 requires different independent settings according to material cooling, each intelligence
The independent control of temperature control valve (TCV) 41, so each cooling circuit 4 can automatically be adjusted according to the change of environmental condition and produce load
The flow in pipeline is saved, and will not be influenced each other.
