Abstract

The invention discloses an intelligent pilot-operated automatic embolism, high-efficiency gas-saving, blockage control and anti-wear control system. Each furnace in a power plant is only provided with two main ash conveying pipes leading to the ash storage; The first ash conveying main pipeline transports ash to the ash storage; the remaining electric fields are combined into the second conveying unit, and the second ash conveying main pipeline is used to transport ash to the ash storage; along the direction of the first ash conveying main pipeline and the second ash conveying main pipeline Pilot ash conveying companion air pipes are set respectively, the first main ash conveying pipe and the second ash conveying main pipe are respectively equipped with first plug valves, the air inlet of the first stop valve is connected with the pilot ash conveying companion through the first pilot air pipe and the second ash conveying main pipe. The trachea is in fluid communication, and the air outlet of the first plug valve is in fluid communication with the first ash transport main pipeline or the second ash transport main pipeline. The invention has the advantages of simple system configuration, few fault points, long-distance transportation, long service life and high reliability.

Description

technical field [0001] The invention relates to the technical field of ash transportation. Specifically, it is an intelligent pilot-operated automatic embolism control system with high efficiency, gas saving, blockage control and anti-wear control system. Background technique [0002] The ash produced by the electric field is generally out of stock, economizer, air preheater, one electric field, two electric field, three electric field, four electric field, five electric field or bag one, two, three rows. There are various layouts of electric field ash conveying pipelines, the common one is coal economizer, out of stock merged into one electric field, one ash conveying pipeline for one electric field, one ash conveying pipeline for second electric field, one for three electric fields, four electric fields and five electric fields The other is a single ash pipeline for the economizer, one ash pipeline for the A / B side of the first electric field, one ash pipeline for the sec...
