Multi-functional pulse-jet ash removal control device

Abstract

A multi-functional pulse injection control device, which solves the problems existing in the prior art that require different control modes for different dust cleaning methods, increases costs, and requires a large amount of construction. It consists of a pulse valve, a cylinder valve plate, a control switch, and a button. The main technical points of the control circuit are as follows: a three-position transfer switch with three normally open contacts is used, and the cleaning mode selection switch for off-line cleaning, online cleaning, and manual cleaning is also used in the cleaning room. The button is the same as the manual cleaning button of the pulse valve in the cleaning room, and uses the one-way conductivity of the diode to form a matrix connection to control each pulse valve. The other end of the pulse valve coil with the same sequence number in each cleaning room passes through a single Connect the conduction diode to the negative pole of the DC 24V power supply. Its structural design is simple, and the same control mode can realize simultaneous selection of cleaning room, offline cleaning, online cleaning, manual cleaning, etc., which can significantly reduce costs and reduce on-site construction.

Description

technical field [0001] The invention relates to a dust removal control device for a dust collector, in particular to a multi-functional pulse pulse which uses the same control circuit to simultaneously select the selected dust removal room, offline dust removal, online dust removal, manual dust removal, etc. Injection control device. It is mainly suitable for the dust removal control device of the low-pressure pulse bag filter used in metallurgy, petroleum, chemical industry, power plant and other places, and belongs to the field of environmental protection equipment. Background technique [0002] There are two types of dust removal methods for large and medium-sized low-pressure pulse bag filters used in metallurgy, petroleum, chemical industry, power plants and other places: off-line and on-line. The so-called off-line dust cleaning means that after the cylinder valve plate is closed to block the air flow in each dust cleaning room, the compressed gas is blown back to cle...
