Bag-type dust remover AC and DC matrix control circuit

Abstract

The invention discloses a bag-type dust remover AC and DC matrix control circuit which comprises at least one chamber, at least one lifting valve and pulse valve. The live line of an AC power supply is divided into two signal wires through two antiparallel diodes. The two signal wires are connected to the lifting valves or pulse valves of all chambers in a matrix circuit through the relay connectors of the lifting valves or pulse valves. Two reverse diodes are connected in series between the lifting valve or pulse valve coils and the two signal wires. The zero line of the AC power supply is connected to all lifting valves and pulse valves of a corresponding chamber in the matrix circuit through the relay connector of the chamber. According to the circuit, when a dust remover removes dust, the matrix circuit can reliably allow the corresponding lifting valve and pulse valve to act, and misoperation is prevented. Since the DC power supply can be viewed as the half cycle form of the AC power supply, the embodiment is also suitable for the matrix control of the DC power supply in the condition of no change, and the anode and cathode of the DC power supply can be exchanged.

Description

technical field [0001] The invention belongs to the field of electrical technology, and relates to a bag filter, in particular to an AC and DC matrix control circuit for the bag filter. Background technique [0002] Today, when environmental pollution is serious, the state has issued strict environmental protection policies, and many baghouses have been launched all over the country. At the same time, many original baghouses need to be remodeled. The application prospects of baghouses are very broad. [0003] The dust cleaning characteristics of the bag filter are: each dust collector is divided into multiple chambers, and each chamber has one (or two) poppet valves and several (up to dozens) pulse valves. Each chamber takes turns to clean the dust, that is, only the poppet valve and pulse valve of a certain chamber act at the same time; during the dust cleaning period of the chamber, the poppet valve always acts, and several (up to dozens) pulse valves act in turn.

Problems solved by technology

However, there are a small number of old bag filter poppet valves and pulse valves whose coil voltage is AC220V, and the traditional matrix circuit cannot be used for control during technical transformation; there are also some users who insist on newly built bag filter poppet valves And pulse valve coil voltage adopts AC220V, also cannot be controlled by traditional matrix circuit
