Example Embodiment

[0012] An automatic descaling control system for an electric heating steam generator, including a PLC controller 1, which is connected with switching devices 2, 3 that control the start or stop of the PLC controller, and an output pole Q1 of the PLC controller and control steam The generator working power relay J1 is connected, the other output pole Q6 of the PLC controller is connected to the descaling agent control valve J6 that adds descaling agent in the control item steam generator, and the other output pole Q9 of the PLC controller is connected to the control steam The blowdown solenoid valve J9 for the blowdown work of the generator is connected.

[0013] The descaling control valve is a solenoid valve that the PLC controller performs delay control after receiving the stop signal of the switch device for controlling the PLC controller to stop.

[0014] The sewage solenoid valve is a solenoid valve that is opened and closed by PLC for delay control.

[0015] There is also a 24...

Abstract

The invention discloses an automatic descaling control system of an electric heating steam generator, which includes a PLC controller, wherein the PLC controller is connected with a switch device for controlling the starting/stopping of the PLC controller; one output stage of the PLC controller is connected with a power supply relay for controlling the steam generator to operate; another output stage of the PLC controller is connected with a detergent control valve for controlling the feeding amount of the detergent into the steam generator; and another output stage of the PLC controller is connected with a blowdown electromagnetic valve for controlling the blowdown of the steam generator. The automatic descaling control system has reasonable structure and excellent working performance, and can realize automatic descaling.

Description

technical field [0001] The invention relates to an automatic descaling control system for an electric heating steam generator. Background technique [0002] For products such as steam generators, the country has clearly stipulated that demineralized water or distilled water must be used, but the price of these two types of water is relatively high, which will increase a lot of production costs. Most garment factories use ordinary tap water, while Tap water is rich in a variety of mineral ions. During the heating process, these ionic components undergo chemical reactions and accumulate on the heating surface to form a layer of white scale with extremely poor thermal conductivity. This is scale. Heat pipes will prolong the heating time, increase energy consumption, insufficient steam and poor steam quality, and in severe cases, the heat pipes will burn out; in addition, the accumulation of scale on the pipes will cause pipe blockage, and cause failure of water pumps and water ...
