Abstract

The utility model belongs to a boiler dust remover, which is on the basis of the present centrifugal separation dust remover, makes use of the principle of rotational flow and atomisation for absorbing deposition, and forms a dust closed-circuit circulation system by adding a dust remover. The device is composed of rotary stream pipes, fume pipes, an atomizer, settling sloping plates, a dust removing bucket, etc. The dust is moistened and increased with weight for many times. The dust removing purpose can be finally realized by the deposit absorption and the inertness collision separation.

Description

Enclosed dual-cyclone high-efficiency dust-collector

The utility model relates to the dust arrester of coal-burning boiler or industrial furnace ash-laden gas, belongs to atmospheric environment protection equipment.

Existing smoke dust-removing equipment generally can be divided into dry dust removal and wet dust removal two big classes.In the dry-type dedusting equipment, gravity or inertia force efficiency of dust collection are low, do not reach the dedusting requirement, and electrostatic dust removing method, because of the equipment manufacturing cost height, floor space is big, so fail to be applied.Type dedusters such as wet-scrubbing equipment such as spray, moisture film, washing, general water consumption and floor space are all bigger, need to build settling tank, and the periodic cleaning bed mud also has secondary pollution and water at low temperature shortcoming such as to freeze during discharging, be subjected to more restriction in use.

The purpose of this utility model is to provide a kind of floor space little, and dust removal performance is reliable, and the dust arrester of non-secondary pollution is integrated centrifugation, wet dust removal, rotational flow dust-removing, to reach the high purpose of compact conformation efficiency of dust collection.

Fig. 1 is the utility model structure chart.

Fig. 2 is the structure chart of the utility model deduster A.

The utility model is finished like this, on the basis of existing centrifugation deduster B, increase by a deduster A, it is by swirl vane (1), smoke exhaust pipe (2), atomizer (3), sedimentation swash plate (4), dust removing funnel (5), dedusting mouth (6), two groups of little swash plates (7), (8) and exhanst gas outlet compositions such as (12), the discharge-channel (10) of centrifugation deduster B is connected to the fume inlet passage (11) of deduster A, and the smoke exhaust pipe exterior of its fume inlet passage (9) and deduster A constitutes flue dust closed cycle loop.Corresponding smoke exhaust pipe below each swirl vane, atomizer is located at respectively between sedimentation swash plate top and the two groups of little swash plates, when flue dust enters deduster A from fume inlet passage (11), when swirl vane, flue dust is centrifugated into two parts, wherein the grit that quality is bigger is separated to the smoke exhaust pipe outside, deliver among the centrifugation deduster B by the effect of air-introduced machine, bigger particle falls into the bottom of deduster, discharge by the dedusting mouth, finish first order dedusting, and the flue dust of sedimentation does not enter once more in the deduster A fume inlet passage through the discharge-channel (10) of centrifugation deduster B, repeats above dust removal process and finishes a flue dust cyclic process.The less grit of its quality passes through smoke exhaust pipe, atomizer, sedimentation swash plate, at this moment most of grit sedimentation absorption.Inertia collision and fall into dust removing funnel and finish second level dedusting.Then the fraction grit rises under the air-introduced machine effect by in two groups of little swash plates and the middle atomizer process, and because of the change of flue gas flow direction, flue dust lands because of collision atomizing and inertia force effect own, finishes third level dedusting.Drop in the dust removing funnel, discharge by dedusting mouth (6), through 3-stage dust-removal, flue gas after being purified is discharged from exhanst gas outlet (12), finishes the circulation dust removal process.

The utility model adopts the two-stage dedusting because centrifugation, wet dust removal, rotational flow dust-removing are integrated, so the concrete structure compactness, floor space is little, and the characteristics that dust removal efficiency is high are compared with the water dust scrubber of equivalence, and efficiency of dust collection can reach 97.8%.

This case is in implementation process, and swirl vane adopts screw type, has 16, and smoke exhaust pipe is to there being 16, and sedimentation swash plate angle of inclination is 60 degree, and dust removing funnel is tapered, and the bottom has the dedusting mouth, can connect dust-removal cloth-bag.
