Problems solved by technology

[0002] At present, in environmental protection equipment, cyclone dust collectors are widely used. The working principle of this dust collector is to make the dust-laden air flow rotate at high speed in the cylinder, and the dust particles are attached to the wall by centrifugal force to capture the dust. Its advantages are: it has a simple structure, It has the characteristics of convenient maintenance and low price, but its disadvantage is that the dust removal efficiency is not only affected by the inlet wind speed, but also by the dust particle size and density. The larger the particle size and the higher the density of the dust, the higher the efficiency at the same inlet wind speed.
However, its dust removal efficiency is not high, generally only 80-90%, especially for fine particles, the dust removal efficiency is even lower, which cannot meet the current environmental protection requirements for smoke and dust emission indicators

Embodiment Construction

[0016] The structure and working principle of the present invention are described in detail in conjunction with accompanying drawings.

[0017] From figure 1 It is known that the side of the cyclone dust collector 1 is the air inlet, and the air inlet needs to be purified. On the one hand, the dry ash is discharged from the ash hopper 16 and the rotary ash discharge valve 17 under the cyclone dust collector, and the cyclone dust collector is connected in series as an elbow 2. Connect the wet fiber grid dust collector 4 through the variable diameter pipe 3, and connect the vertical sedimentation tank 8 with the drain pipe 6 and exhaust pipe 7 below. The ash discharge valve 11 below the box is discharged. The upper part of the cyclone dust collector 1 is an exhaust pipe 13, the lower part is a cylinder 14, the lower part of the cylinder 14 is a cone 15, and the bottom is an ash hopper 16 and a rotary ash discharge valve 17; the other part connected in series with the cyclone du...

Abstract

A combined cyclone-wet fibre grate cleaner with a reverse U-shaped structure is composed of a cyclone cleaner and a wet fibre grate cleaner, which are serially connected via an elbow pipe and diameter varied pipe. A water cleaner is installed to the side surface of said wet fibre grate cleaner. Its advantages are high dust removing efficiency and simple structure.
