Abstract
The utility model relates to a water circulating system of chemical equipment, which comprises a water inlet manifold and a water outlet manifold of a vacuum cooling system, wherein a vacuum pump of the vacuum cooling system is driven by a motor, the water inlet manifold and a water return manifold are communicated with water utilization equipment respectively through an independent water inlet branch tube and an independent water return branch tube, the water inlet branch tube is respectively provided with an electromagnetic valve, the water inlet branch tube and the water return branch tube are respectively provided with a temperature sensor, the temperature sensors, and the electromagnetic valves and a motor frequency converter are respectively accessed into a distributed control system. In the water circulating system, the opening degree of the electromagnetic valve is adjusted according to the temperature difference of the various water utilization equipment, so that the flow of the water inlet branch tubes is controlled, the circulating flow of cooling water of the water utilization equipment at a near end is reduced, the circulating flow of cooling water of the water utilization equipment at a remote end is improved, and the temperature difference span of the water utilization equipment at the remote end can be shortened; and simultaneously, the distributed control system controls a motor frequency converter to change frequency according to the temperature difference of the water utilization equipment at the remote end, so that the too large temperature difference of the water utilization equipment at the near end can be prevented from influencing the production, and the energy consumption can be greatly reduced.
Description
Technical field
The utility model relates to a kind of chemical industry equipment circulation, particularly a kind of chemical industry equipment circulation of energy-conserving and environment-protective.
Background technique
Traditional chemical industry equipment circulation comprises water inlet manifold, the outfall sewer of vacuum cooling system, and the vacuum pump of vacuum cooling system is by motor driving, and water inlet manifold and return main are communicated with watering equipment by independent water inlet arm and return branch respectively.Water inlet manifold is when carrying out the supply of watering equipment, because the near-end watering equipment has a narrow range of temperature, and the watering equipment of far-end exists the temperature difference bigger, need to improve vaccum pump motor power and strengthen the global cycle flow, to realize the reduction of the far-end watering equipment temperature difference, it is higher to consume energy.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of chemical industry equipment circulation of energy-conserving and environment-protective.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of chemical industry equipment circulation, the water inlet manifold, the outfall sewer that comprise the vacuum cooling system, the vacuum pump of vacuum cooling system is by motor driving, and described water inlet manifold and return main are communicated with watering equipment by independent water inlet arm and return branch respectively; Its innovative point is: on the described water inlet arm solenoid valve is installed all; On described water inlet arm and the return branch temperature transducer is installed, this temperature transducer, solenoid valve and motor frequency conversion device all insert Distributed Control System.
Advantage of the present utility model is: the temperature difference by each watering equipment is regulated the solenoid valve aperture, control the flow of the arm of respectively intaking, reduce the circular flow of near-end watering equipment cooling water, improve far-end watering equipment cooling water circular flow, dwindle far-end watering equipment temperature difference span, simultaneously, Distributed Control System is controlled the motor frequency conversion device according to the temperature difference of far-end watering equipment and is changed frequency, avoid the influence of far-end watering equipment excessive temperature differentials to produce, greatly reduce energy consumption.
