In the present invention, as further scheme, the cold water pipes are connected with reflux line, and the reflux line passes through intelligence Energy three-way valve is connect with cold water pipes, in the circuit that reflux line is formed with cooling water pipe, is equipped with heat exchanger;The intelligence Three-way valve go out be connected with measure cold water pipes temperature temperature measuring equipment, the temperature-detecting device by PLC system with Intelligent three-way valve connects.The effect of reflux line is, when water flow temperature is too low, in order to avoid the heat in heat exchanger Amount reduction is too fast, by the way of cold-water reflux so that and the temperature of flow recycles in the exchanger of single area, so that The initial temperature of cold water can improve, convenient for being brought rapidly up.
In the present invention, as further scheme, the sewage pipe goes out equipped with slag-discharging device, and the slag-discharging device includes shell, institute It states and is equipped with liquid outlet at shell, be equipped with deslagging rotating knife in the shell, the shell tail portion is slag-drip opening, at the slag-drip opening Equipped with slag charge collection port, meausring apparatus is equipped at the deslagging collection port.By measuring bed drain purge, it will be appreciated that local sewage Dregginess, to cope with different degrees of sewage scheme.
In the present invention, as further scheme, hot water moisturizing pipeline, the hot water water supply pipe are equipped in the reflux line Airflow calculator is equipped in road.Moisturizing pipeline is hot water pipeline, when heat exchanger can not be in a short time to the water in cold water pipe When being heated up, by filling into hot water, so as to improve the initial temperature of cooling pipe.By by airflow calculator, Rate of water make-up can be calculated, to understand local moisturizing demand, to calculate the energy value of heat exchange amount.
In the present invention, as further scheme, the moisturizing pipeline is connect with electric heating system, the electric heating system and moisturizing Pipeline valve is controlled by PLC system, and the PLC system is connect with temperature measuring equipment.The unlatching of moisturizing pipeline, and intelligence The unlatching of three-way valve feeds back to PLC system by temperature measuring equipment, by it into trip temperature management and control, to realize temperature Intelligence.
The beneficial effects of the invention are as follows:
1. the present invention carries out operation and control using full automatic PLC control system, have a reliability, safety, automatically Equal technical characteristics have the preferable market competitiveness, can be according to preventing using water when carrying out heat exchange, due to water temperature It is too low, and temperature is caused to heat up slow defect.
2. the present invention can count the waste residue of sewage and rate of water make-up, statistical data is formed, in order to be directed to sewage Environment and rate of water make-up carry out pipe design.
3. the configuration of the present invention is simple carries out Electronic Design by existing equipment, and according to the present invention, then can be achieved, It is promoted the use convenient for the industry.
