Operation control system for combustion gas pulse soot blower

Abstract

The invention discloses an operation control system for combustion gas pulse soot blowers, which is used for controlling multiple groups of combustion gas pulse soot blowers. The system comprises a touch screen, a programmable controller, an input unit, a communication unit, a temperature sensor, a pressure transducer, an ash production amount weighing device and a corresponding connecting circuit, wherein the touch screen is connected with the programmable controller, the touch screen displays running states of the multiple groups of combustion gas pulse soot blowers; and the temperature sensor is arranged in the multiple groups of combustion gas pulse soot blowers, and is connected with the programmable controller. The operation control system further comprises an instruction input unitconnected with the programmable controller, and an operator can input a control instruction to the programmable controller according to a time curve of temperature to pressure. In the operation control system for combustion gas pulse soot blowers provided by the invention, the touch screen and the programmable controller are adopted to conduct direct, convenient and precise control on the multiple groups of combustion gas pulse soot blowers, and to arrange reasonable control conditions.

Description

technical field [0001] The invention relates to a control system, in particular to an operation control system of a gas pulse soot blower. Background technique [0002] Gas pulse soot blower, as a new type of high-efficiency and energy-saving soot blower, has been widely used in soot blowing on the heating surface of various boiler heat exchangers. Its working principle is mainly to mix air and gas (mainly acetylene) in a deflagration tank, and then ignite it. The high temperature and high pressure airflow generated by the explosion is directed to the heating surface of the boiler for soot blowing. [0003] Due to the danger of the working principle of the pulse sootblower, it is determined that its control system must not only reliably control the operation of the sootblower, but also fully consider the safety of the system - mainly adding gas leakage and ignition tank tempering temperature detection. At the same time, the system safety detection must have a certain anti-...

AI Technical Summary

Problems solved by technology

At the same time, the system safety detection must have a certain anti-interference ability to prevent the interference of the industrial environment from interrupting or terminating the operation of the soot blowing equipment due to false alarms and affecting the soot blowing effect.

[0004] The control system of the gas pulse soot blower in the prior art is mostly composed of components such as relays and electrical switches. Each ignition cabinet corresponds to a set of control circuits, resulting in a large control system; moreover, so many electrical Combining components together also increases the possibility of failure
