The invention provides a dust explosion suppression controller, which is connected with a suppressor and comprises an intelligent detection unit and a control unit, wherein the intelligent detection unit comprises an integrated control panel used for collecting static explosion pressure in protected equipment and the explosion pressure rising rate and a connecting wire used for transmitting collected alarm feedback signals to the control unit; the control unit is used for recording the static explosion pressure in the protected equipment, the explosion pressure rising rate, the alarm frequencyand the alarm time in real time, and comprises a single-area control unit and a multi-area control unit; the single-area control unit is used for controlling the suppressor in one area; and the multi-area control unit is used for controlling the suppressors of the four, eight, sixteen or thirty-two areas. The controller provided by the invention can continuously monitor the dangerous situation which may cause explosion, and can immediately process the detected alarm feedback signal, drive the system to inhibit action and isolate initial explosion at the same time.
Description
technical field [0001] The invention relates to the technical field of dust explosion suppression, in particular to a dust explosion suppression controller. Background technique [0002] A large amount of powder and dust will be produced in industrial production. These powders and dust are mixed with oxygen in the air. When reaching a certain concentration, if there is an ignition source, an explosion accident will occur. In industry, when processing, transporting or storing certain raw materials, light-weight equipment is used, but these equipment are not designed to resist the high pressure generated by dust explosion in a very short time, so safety protection measures must be taken To protect these equipment to deal with these flammable solid particles. As the internationally recognized most advanced dust explosion-proof system solution, the explosion suppression system should be widely used, and the controller is used to control the action of the explosion suppression s...
