Description
Technical field
The utility model belongs to system's heating equipment, particularly adopts the heat exchange unit of microprocessor.
Background technology
In present heating system, it is a development trend that the secondary heating plant adopts the heat exchange of water water, advantage and the characteristics that oneself is arranged are compared in the heat exchange of water water with steam-water heat exchanging, at first pipeline is realized the buried interference that can not be subjected to extraneous factors such as street completely, has not only solved the problem of setting up of jet chimney but also beautified environment.Next is a safety, and jet chimney mostly is the high temperature that sets up in the open and the pipeline of elevated pressures is arranged, in case reveal the crowd that hurts easily.There is buried water waterpipe to reduce jet chimney again and carries scattering and disappearing of heat that high-temperature steam causes, realized energy savings because of open-air.In present heat exchange station, the heat exchange unit does not have fixing pattern, and the user needs the heat exchanging station to carry out independent design and buying, installation.Often also only be simple equipment and being connected of pipeline, the equipment operation needs operations staff's real-time monitoring of specialty.Can not realize effectively energy-conservation operation of equipment.
The utility model content
Need personnel's real-time monitoring and the few deficiency of control parameter in order to overcome existing heat supply network heat exchange unit, the purpose of this utility model provides the whole heat exchange unit of a kind of intelligence, the whole heat exchange unit of this intelligence not only can be realized unmanned operation automatically by setup parameter, and can be able to determine heating load because of climate change and reach energy-efficient effect.
The technical scheme that its technical problem that solves the utility model adopts is: the whole heat exchange unit of a kind of intelligence comprises with heat exchanger and once holds the once net feed pipe that joins, net return pipe once; The secondary pipe network feed pipe is connected the heat exchanger secondary terminals, the secondary pipe network return pipe joins through circulating pump and heat exchanger secondary terminals; Filling pipe joins through small pump and circulating pump, it is characterized in that: be connected on once calorimeter on the net feed pipe and be installed in that each supplies water, pressure, temperature sensor on the return pipe link to each other with the controller data collection terminal respectively, controller output is joined through frequency-variable controller and circulating pump, small pump, and is connected with electric control valve on the net return pipe once.
Connecting touch-screen on the described controller, the controller data collection terminal is also connecting outdoor temperature sensor.
On the described secondary pipe network return pipe safety valve that delivery pipe is housed is installed.
Native system is based on the SCADA system of PLC, field controller is at first gathered the various signals at scene, (this temperature is different with the area with the building normal temperature of gathering, heating duration is different and set), environment temperature, after heat medium temperature carries out integrated treatment, send instruction control corresponding apparatus.When reducing as environment temperature, building requires heating load big, and controller output order control heat-exchange system strengthens the heat exchange amount, and supply water temperature is with regard to corresponding raising; Reduce heating load otherwise then regulate heat-exchange system, reduce supply water temperature.Whole heating season of this process is all carrying out, and the energy that accumulation gets up to save is surprising.This heating load when having guaranteed indoor optimum temperature, has been saved the energy with the method for operation that the variation of environment temperature changes to greatest extent.Native system is also determined the control curve of various places according to local circumstance, comprise the heat supply characteristic of different regions; Nighttime sleep status adjustment mode, office building regulative mode festivals or holidays etc. can adapt to the requirement of different regions different cities.This system organically merges advanced person's computer technology, the network communications technology, automated control technology and superb heat transfer technology, realizes the full automation operation, need not special messenger's post.
The performance characteristics of control system:
(1) reserves communication, for Centralized Monitoring is laid a solid foundation.Characteristics at each heat exchange station distributes and relatively disperses in order to save manpower, reduce heat waste, and system can reserve communication interface, for networking monitoring is from now on laid a solid foundation according to customer requirements.
(2) miniaturization, integrated.This control system volume ratio is less, and is powerful, and system cost is cheaper than like product, and it is many to be fit to measuring point, and control requires than higher heat-exchange system.
(3) adaptability, reliability, security.This control system antijamming capability is very strong, under rugged environment, still can carry out work, the incidence of minimizing accident. each heat exchange station safety, stable operation are directly connected to huge numbers of families, so to each links such as control program establishments, native system all has reliability and security preferably from the structural design of control system, software and hardware product quality.
(4) retainability.System has powerful warning and fault self-diagnosis function at systems soft ware, application software and hardware aspect, makes things convenient for the engineer that the system failure is analyzed and safeguards.
(5) extensibility.System has certain standard and widely used software and hardware product, leaves certain surplus in actual production, for future heat exchange station enlarging and the change of system lay the first stone.
(6) opening.Opening is the common requirements of user to control system.Along with the development of computer and network technologies and popularizing of application, people more and more need Process Control System and management information system interactive information, thereby realize that management is integrated with control.
