Abstract

The invention provides a control method and a control system for a bag-type dust collector. The control system comprises a dust conveying control module, a dust cleaning control module and a preheating cycle control module, wherein the dust conveying control module is used for controlling the dust conveying based on the selected dust conveying mode; the dust cleaning control module is used for controlling dust cleaning sequentially in small rooms based on the selected dust cleaning mode and the selected small rooms; the preheating cycle control module is used for controlling a heater to be started and to run until the temperatures of all the small rooms reach the preset temperatures. The control method and the control system of the bag-type dust collector are stable and reliable, so that the whole production is normally carried out in sequence, and the flue gas emission status is good.

Description

Technical field [0001] The invention relates to the incineration and flue gas treatment of garbage and other wastes, and in particular to a control method and control system for a bag filter. Background technique [0002] Garbage incineration is currently the most widely used garbage treatment method at home and abroad. The biggest advantage of this method is the high degree of garbage recycling and reduction. The garbage incineration plant is built around the city, it is convenient to transport garbage, and can provide electricity or heat to the city, which produces good economic benefits. Modern garbage incinerators are equipped with good smoke purification devices to reduce air pollution. The flue gas treatment system adopts the process of selective non-catalytic reduction (SNCR) + rotary spray semi-dry method + dry method + activated carbon injection + bag dust removal. The function of the bag filter is to collect the fine dust in the flue gas while collecting lime powder a...
