Softened water pre-heating control system for softened water tank

Abstract

The invention discloses a softened water pre-heating control system for a softened water tank. The softened water pre-heating control system comprises a water heater, a water temperature detection unit, a controller, a parameter setting unit, a display, a position detection unit, a water level detection unit, a working parameter detection unit, an interval computation module, a temperature conversion module, a time calculation module and a delay control module, wherein the controller is used for correspondingly controlling the water heater; the position detection unit is used for detecting the position of an area which is detected by the water temperature detection unit; the interval computation module is used for computing a difference value of the detection information of the position detection unit and the water level detection unit; the delay control module is connected with the controller; and the controller is used for automatically setting the delay time of the delay control module according to time parameters which are calculated by the time calculation module. The softened water pre-heating control system for the softened water tank is reasonable in design, and easy and convenient to operate, has a good using effect and high degree of intelligence, and effectively overcomes the defects of inconvenience for operation, arrangement of a plurality of temperature detection devices for detection, large data processing amount, low temperature detection accuracy, and the like of the conventional softened water pre-heating control system.

Description

technical field [0001] The invention relates to an automatic control system, in particular to a softened water preheating control system for a softened water tank. Background technique [0002] Demineralized water is water after softening treatment, that is, water from which some or all calcium and magnesium ions have been removed. During the actual use of the heating boiler, the softened water in the softened water tank is preheated first, and the softened water is preheated to a certain temperature (specifically, about 40°C). Nowadays, when preheating the softened water in the softened water tank, a set of water heaters arranged in the softened water tank is used for softening and preheating, and the working parameters of the water heater are controlled and adjusted by the controller to achieve control The purpose of softening the temperature of hot water in the water tank. At the same time, in the actual temperature adjustment control process, it is also necessary to in...
