Description
Technical field
The present invention relates to a kind of control device, especially a kind of high system automatic control device of heat.
Background technique
The high system of heat is used to heat production auxiliary water, and the high heat source of heat is steam, by manually to the adjusting of steam valve
The high soaking condition of heat is controlled, to control the temperature of water.But the control manually changed entirely in this way, not only makes hot water temperature
When it is high when it is low, influence the supply quality of hot water in use process, and open steam valve for a long time, cause the wave of the energy
Take.
Since actual use provides, only partial period just uses the system to carry out water temperature control daily, and opens simultaneously
Condensed water elimination valve discharges condensed water.By the temperature sensor in water tank, when water tank temperature reaches 60 degrees Celsius,
Staff will turn down or directly steam off valve, stopping are heated.And the staff when temperature is lower than 50 degrees Celsius
Steam valve opening heats it.In the whole process, the control whole process of temperature depends on manual control, not only increases
Cost of human resources influences heat since the situation that hot water is not supplied occurs in the variation of water consumption often also in control process
The supply quality of water.And during entire manual control, steam does not supply precisely, so that the energy consumption in workshop greatly increases.
Summary of the invention
To solve the technical problem in above-mentioned background technique, the present invention provides a kind of high system automatic control device of heat,
Solving the high use process of heat must cause water temperature unstable, energy by opening hand-operated valve supply steam manually to control water temperature
The problem of consumption increases.After being mounted with automatic control device, hot water supply quality can be improved, reduce labor cost and energy consumption, together
The intelligentized control method of Shi Shixian runing time.
Specifically, the high system automatic control device of heat of the present invention comprising have PID controller, air bladder
Regulating valve and temperature sensor；The PID controller is connect with pneumatic diaphragm control valve, and the pneumatic diaphragm control valve is set
It is placed in the high system pipeline of heat, for controlling opening or closing for pneumatic diaphragm control valve by PID controller, thus realization pair
The adjusting of the high system pipeline water temperature of heat；It is additionally provided with temperature sensor in the high system pipeline of heat, the temperature sensor and PID
Controller connection, for the high system pipeline water temperature of heat to be sent in PID controller by temperature sensor.
It in the present embodiment, further include having control touch screen, which connect with PID controller, is used to PID
Controller carries out instruction input.
In the present embodiment, the start-up temperature of the PID controller is 50 DEG C, and stopping temperature is 65 DEG C.
In the present embodiment, the control touch screen uses Siemens's industrial control software STEP7 PLC program, and uses
Wincc flexible makes touch screen control picture.
Detailed description of the invention
Fig. 1 is the invention high system automatic control device closed-loop control schematic diagram of heat.
Specific embodiment
With reference to embodiments and technical solution of the present invention is described in detail in respective drawings, so that art technology
The solution of the present invention can be more clearly understood in personnel, but the protection scope being not intended to limit the present invention.
The present invention provides a kind of high system automatic control devices of heat, and solving the high use process of heat must be by manually opening
The problem of hand-operated valve supply steam causes water temperature unstable to control water temperature, and energy consumption increases.It is mounted with automatic control device
Afterwards, hot water supply quality can be improved, reduce labor cost and energy consumption, while realizing the intelligentized control method of runing time.
Specifically, the high system automatic control device of heat of the present invention comprising have PID controller, air bladder
Regulating valve and temperature sensor；The PID controller is connect with pneumatic diaphragm control valve, and the pneumatic diaphragm control valve is set
It is placed in the high system pipeline of heat, for controlling opening or closing for pneumatic diaphragm control valve by PID controller, thus realization pair
The adjusting of the high system pipeline water temperature of heat；It is additionally provided with temperature sensor in the high system pipeline of heat, the temperature sensor and PID
Controller connection, for the high system pipeline water temperature of heat to be sent in PID controller by temperature sensor.
It in the present embodiment, further include having control touch screen, which connect with PID controller, is used to PID
Controller carries out instruction input.
In the present embodiment, the start-up temperature of the PID controller is 50 DEG C, and stopping temperature is 65 DEG C.
In the present embodiment, the control touch screen uses Siemens's industrial control software STEP7 PLC program, and uses
Wincc flexible makes touch screen control picture.
According to optimization design, group is by steam control valve from common valve replacement at may participate in the pneumatic thin of PID control
Film valve.
And control touch screen is increased outside cylinder, and program, wincc flexible production touch are write by Step7
Screen control picture, the control system high to entire heat are improved.By control cabinet by being placed on outside cylinder, convenience is real-time for group
Monitoring and its operation.
The high system of heat after the installation improvement of this self-control device, work can be completed by not needing artificial intervention, all
Temperature adjust and the working time all be automatically control.According to the time of programming high system of heat automatically into operating mode and
Shutdown mode.The regulation of temperature is determined according to programmed values.The upper limit value of hot high water temperature is defaulted as 65 DEG C under normal circumstances,
Lower limit value is set as 50 DEG C, and program can judge automatically whether current temperature is lower than lower limit value, if lower than steam valve meeting if lower limit value
It automatically opens, hot high flush tank is heated.After actual temperature is equal to upper limit value, steam valve is automatically closed.And works as and use water
When amount increases very fast, the upper limit value of system meeting automatic water temperature regulation makes hot water deposit value get a promotion, to solve hot water confession
Answer insufficient problem.
It is as follows by averagely energy saving can monthly be calculated before improving and after improving:
Quantity of steam is monthly used in 2015 annuals are as follows: 418.54t/10=42t
Quantity of steam is monthly used in 2016 annuals are as follows: 87.78t/10=9t
The signature coefficient of steam is 0.095
It can be saved with steam every year after improvement: 0.095*12=37.62 tons of mark coals of (42-9) *.
The above is only the preferred embodiment of the present invention is described, technical solution of the present invention is not limited to
This, those skilled in the art's made any known deformation on the basis of major technique design of the invention belongs to the present invention
Claimed technology scope, the specific protection scope of the present invention are subject to the record of claims.
