Description
Technical field
The utility model belongs to heating field, is specifically related to a kind of unmanned heat exchange station control device.
Background technology
In city heating system now, the thermal source of heat exchange station generally has two kinds of forms, and the first is that oneself boiler supplying hot water is to heat exchanger; The second is that heat exchange station is supplied to heat exchanger from steam power plant's purchase hot water.
The hot water of thermal source supply is called once and supplies water, and the water that enters after heat exchanger with secondary network that once supplies water carries out heat exchange, descends through the coolant-temperature gage of a secondary net of heat exchange, is primary water, flows back to the thermal source place; The coolant-temperature gage of the secondary network of process heat exchange rises, and is secondary water-supply, flows to hot user and carries out heat exchange again, locates to descend through the coolant-temperature gage of heat exchange the user, is called the secondary backwater, flows back to heat exchanger.Operation principle as shown in Figure 1.Metering and control method that the heat exchanging station is traditional be, mounting temperature sensor, pressure sensor and by-pass valve control respectively on supply channel, primary water pipeline, secondary water-supply pipeline, secondary returning water lines.The heat exchange station staff according to the rules each hour the reading of once checking meter, and record is according to the aperture of real-time pressure, temperature, outdoor temperature and the hot user's of pipe network feedback manual adjustment valve and the frequency of frequency converter.The problem that this way exists is: take time and effort; Regulating effect varies with each individual; Receive that to judge the time after user feedback oversize etc. again.
Summary of the invention
The purpose of this utility model is to provide a kind of unattended heat exchange station control device, is used for the automatic control of heat exchange station, overcomes the labor intensive that existing control method exists; Regulating effect varies with each individual; The deficiencies such as the conciliation cycle is long.
The utility model is comprised of central control module, temperature collect module (temperature sensor), pressure acquisition module (pressure sensor), control valve opening Executive Module, circulation frequency conversion Executive Module, moisturizing frequency conversion Executive Module, display module; Central control module wherein comprises control valve control submodule, circulation VFC submodule, moisturizing VFC submodule, display sub-module and warning submodule; Temperature collect module is connected with the display sub-module of central control module, and temperature collect module gathers once supply water temperature acquisition module, primary water temperature collect module, secondary water-supply temperature collect module, secondary returning coolant-temperature gage acquisition module, outdoor temperature acquisition module; The pressure acquisition module is connected with the display sub-module of central control module, and the pressure acquisition module is pressure of supply water acquisition module, primary water pressure acquisition module, secondary water-supply pressure acquisition module, secondary returning water pressure acquisition module once; The control valve Executive Module is controlled submodule with the control valve of central control module and is connected; Circulation frequency conversion Executive Module is connected with the loop control submodule of central control module; Moisturizing frequency conversion Executive Module is connected with the moisturizing VFC submodule of central control module; Display module is connected with the warning submodule with the display sub-module of central control module.
Good effect of the present utility model is:, realized that the Automatic Control of heat exchange station is regulated, need not employment on duty, save manpower.The working condition adjustment at heat exchanging station in time, is steadily fully ensureing hot user indoor temperature requirement.

The specific embodiment
Consult Fig. 2, formed by central control module, temperature collect module, pressure acquisition module, control valve opening Executive Module, circulation frequency conversion Executive Module, moisturizing frequency conversion Executive Module, display module; Central control module wherein comprises control valve control submodule, circulation VFC submodule, moisturizing VFC submodule, display sub-module and warning submodule; Temperature collect module is connected with the display sub-module of central control module, and temperature collect module gathers once supply water temperature acquisition module, primary water temperature collect module, secondary water-supply temperature collect module, secondary returning coolant-temperature gage acquisition module, outdoor temperature acquisition module; The pressure acquisition module is connected with the display sub-module of central control module, and the pressure acquisition module is pressure of supply water acquisition module, primary water pressure acquisition module, secondary water-supply pressure acquisition module, secondary returning water pressure acquisition module once; The control valve Executive Module is controlled submodule with the control valve of central control module and is connected; Circulation frequency conversion Executive Module is connected with the loop control submodule of central control module; Moisturizing frequency conversion Executive Module is connected with the moisturizing VFC submodule of central control module; Display module is connected with the warning submodule with the display sub-module of central control module.
Control device of the present utility model is controlled the setting of submodule by the control valve in central control module, can realize three kinds of control models of control valve opening.Secondary water-supply temperature and design temperature that the first temperature collect module collects are done the PID computing, and operation result controls to adjust the aperture of valve; The second carries out the PID computing according to outdoor temperature and secondary water-supply temperature that temperature collect module collects, and operation result controls to adjust the aperture of valve; Provided at times design temperature in the third one day 24 hours, the design temperature of each period and secondary water-supply temperature are carried out the PID computing, and operation result controls to adjust valve opening.By the setting of circulation VFC submodule, three kinds of control models of the frequency conversion that can realize circulating.The first hand switch is controlled; The second carries out the PID computing according to secondary water-supply pressure and setting pressure that the pressure acquisition module collects, the frequency of operation result controlled circulation pump frequency conversion device; The third is according to secondary water-supply and the secondary returning water pressure is poor and setting pressure is carried out the PID computing, the frequency of operation result controlled circulation pump frequency conversion device.By the setting to moisturizing VFC submodule, can realize that the moisturizing VFC has three kinds of control models, the first hand switch is controlled; The second carries out the PID computing according to secondary returning water pressure and setting pressure that the pressure acquisition module collects, and operation result is controlled the frequency of small pump frequency converter; The third logical consequence according to the secondary returning water pressure of pressure acquisition module collection and deviate comparison is controlled the frequency of small pump frequency converter.
