Description

A kind of intelligent heat-exchange unit
Technical field:
The utility model belongs to the heat exchange unit, particularly a kind of intelligent heat-exchange unit that can move automatically.
Background technology:
The load equipment of needed heat (cold) of the heat (cold) such as heat supply, ventilation, air-conditioning, production and life that the heat exchange unit provides each building.The heat exchange unit mainly is made up of heat exchanger, water circulating pump, small pump etc.These heat exchange units often just couple together heat exchanger, water circulating pump, small pump etc. with pipeline, do not have electric-control system, need professional operations staff to monitor constantly during the equipment operation, and floor space is big, control is complicated.In recent years, many heat exchange units have adopted automatic control technology, tentatively solved manually-operated problem, but the electric-control system unreasonable allocation can not reach the optimum control of heat exchange unit.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of intelligent heat-exchange unit is provided, and this unit can realize no worker monitor, automatic warning and floor space is little, operating cost is low.
The technical solution of the utility model is: a kind of intelligent heat-exchange unit, comprise steam inlet, heat exchanger, water circulating pump, small pump, water supply tank, water return outlet, feed water inlet and condensation-water drain, it is characterized in that: steam inlet is connected with heat exchanger by electric control valve, and blast pipe and drain valve are installed on the heat exchanger; One end of circulating pump is connected with heat exchanger, and the other end is connected on the return pipe, and the two ends of return pipe are connected with water return outlet with small pump respectively; The input of electric control valve is connected with the output of control circuit board with the input of small pump.
Above-mentioned heat exchanger adopts shell-and-tube heat exchanger.
Above-mentioned control circuit board adopts the SDC digital servo circuit.
The utility model has the advantages that: 1, can carry out the automatic operation of unmanned guard, automatic water supplement and warning automatically by the control technology of control circuit board.2, simple in structure, security performance good.3, little, the low cost of manufacture of volume.4, can realize the constant temperature heat supply.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is an electrical schematic diagram of the present utility model.
Fig. 4 is a theory diagram of the present utility model.
The specific embodiment:
A kind of intelligent heat-exchange unit comprises steam inlet 17, shell-and-tube heat exchanger 13, water circulating pump 12, small pump 3, water supply tank 1, water return outlet 10, feed water inlet 18 and condensation-water drain 19.Steam inlet is connected with heat exchanger by electric control valve 14, and blast pipe 15 and drain valve 16 are installed on the heat exchanger.One end of circulating pump is connected with heat exchanger, the other end is connected on the return pipe 7 by ball-and-seat 8, one end of return pipe 7 is connected with small pump with dish valve 4 by elbow 6, and small pump adpting flange 2 backs are connected with water supply tank, and the other end is connected with water return outlet 10 by dish valve 9.The input of electric control valve is connected with the output of control circuit board with the input of small pump.Above-mentioned control circuit board adopts the SDC digital servo circuit.
The course of work of the present utility model is: utilize 0.1-0.8MPa steam as thermal source, carry out the carbonated drink exchange with shell-and-tube heat exchanger, adopt advanced control simultaneously, steam is carried out opened and close, reach the purpose that realizes constant temperature water supply.Steam is to enter shell-and-tube heat exchanger by the pipeline that has electric control valve, when water temperature (feedback signal) reaches the temperature (input signal) of setting, being contained in thermal resistance on the unit can input to faint 4-20 milliampere electric current in the signal processing circuit analog signal conversion is become data signal, then data signal being sent into digital processing system handles, the data signal of handling well is outputed to the logical signal discriminator circuit again identify out valve or close valve circuits needed signal, this signal removes to shake to drive by drive circuit after handling through the antivibration circuit more again and closes electric control valve prevention steam and enter in the heat exchanger.When water temperature (feedback signal) is lower than design temperature (input signal), repeat said process, open electric control valve, steam is entered once more carry out work in the heat exchanger, realize constant temperature water supply.
This unit can also be accomplished automatic water supplement or frequency conversion moisturizing, guarantees the normal operation of system.Can also realize simultaneously reporting to the police with out of service automatically automatically.
