Problems solved by technology

There are two kinds of existing granular layer dust collectors, one is the granular layer dust collector of the fluidized bed back blowing dust removal, the particle layer gap works, the back blowing air volume is large, and the operation is inconvenient; the other is the mobile particle layer filter The dust collector removes dust during the movement of the granular layer, and then sieves the granular layer to clean the dust. Due to the movement of the granular layer, the gap between the particles increases, and the dust removal efficiency decreases. In addition, after screening, the requirements for the particles to return to the granular layer are high, which affects the Promotion of the technology

Embodiment Construction

[0026] Examples of the present invention figure 1 As shown, it includes a dust-containing gas inlet hood 1 located at the upper part of the dust collector, a cylindrical particle layer dust collector 2, a packing layer unit cell 3 and a packing 4 of the dust collector, a purified gas outlet hood 5, and The rotary fluidized bed blowback mechanism composed of the exhaust suction hood 8 and the rotating exhaust pipe 9 rotates around the center of the cylindrical granular layer dust collector 2, and the exhaust suction hood 8 is set on the granular layer dust collector. In the air intake cover 1 on the top of the device.

[0027] Such as figure 2 As shown, the cross-section of the cylindrical granular layer dust collector is divided into three parts: the dust-laden airflow dedusting area 10 , the fluidized bed back-blowing ash cleaning area 12 and the sealed isolation area 11 , and each area is composed of several packing grids 13 .

[0028] The present invention is used for bo...

Abstract

A cleaner based on particle-layer dusting technique, fluidized-bed back-blowing cleaning technique and rotary mechanism features that its rotary fluidized bed back-blowing mechanism is composed of exhausting air-sucking hood, and rotary exhausting exhaust tube, it is rotating around the circular center of cylindrical particle-layer duster, and back-blowing airflow flows through said back-blowing mechanism from bottom to top to fluidize the particles in cleaning region for carrying dust outward. Its advantages are continuous and reliable dusting and cleaning, and low cost.

Description

Technical field [0001] The patent of the present invention relates to the technology of industrial gas dedusting, in particular to a rotary fluidized bed blowback granular layer deduster. Background technique [0002] There are many methods of industrial gas dust removal, including single-tube cyclone dust collector, multi-tube cyclone dust collector, cyclone water film dust collector, bag filter dust collector, electrostatic precipitator and granular layer dust collector, etc., which can also be divided into low-temperature dust removal and high-temperature dust removal. . Due to the simple structure of the cyclone type dust collector, the dust content of the gas after dust removal cannot meet the requirements in some occasions; in the case of high temperature dust removal, an electrostatic precipitator or a bag filter is used, and the gas must be cooled to ~150°C, and a blending method can be used. Cold air or cooling with a cooler will increase power consumption. In addi...
