Pulse reverse-blowing ash-removing device with rotary blowing pipes

Abstract

The invention discloses a pulse reverse-blowing ash-removing device with rotary blowing pipes. The pulse reverse-blowing ash-removing device comprises a plurality of blowing pipelines; the bottom side of each blowing pipeline is provided with a plurality of nozzles; each blowing nozzle is arranged above a gas ejector of a corresponding filtering unit; each blowing pipeline is communicated with a reverse-blowing gas storage tank through a pulse reverse-blowing valve; each blowing pipeline is composed of an inner pipe and an outer pipe which are arranged in a sealing and sleeved mode; the nozzles are arranged on the outer pipes; each inner pipe is provided with blowing holes equal to the nozzles; the intervals of the plurality of blowing holes are correspondingly equal to the intervals of the nozzles on the outer pipes; the plurality of blowing holes are sequentially distributed at equal angles along the circumference direction of each inner pipe; and one end of each inner pipe is connected with the pulse reverse-blowing valve through an air supply pipe, and the other end of each inner pipe is connected with a stepping motor. When the device disclosed by the invention is used for removing ash in a pulse reverse-blowing manner, only one blowing hole and one nozzle blow high-pressure gases to the corresponding gas injector at the same time, so that the ash removing efficiency and the reverse blowing intensity can be improved; and air flow in blowing can be corrected automatically, and thus the phenomenon of deviation of blown air flow can be avoided.

Description

technical field [0001] The invention relates to a gas-solid separation device, in particular to a pulse back-blowing dust-cleaning device with a rotary blowing pipe suitable for a rigid filter element. Background technique [0002] In chemical industry, petroleum, metallurgy, electric power and other industries, high-temperature dust-containing gases are often produced; because different processes need to recover energy and meet environmental protection emission standards, these high-temperature dust-containing gases need to be dedusted. High-temperature gas dedusting is a technology that directly separates gas from solid under high-temperature conditions to realize gas purification. It can maximize the use of physical sensible heat, chemical latent heat and kinetic energy of gas, improve energy utilization, and simplify the process at the same time. Save equipment investment.
