Abstract
A kind of cyclone dust extractor with pre-dedusting, having pre-dedusting and cyclone dust removal two parts, in pre-dust removal part, air inlet pipe (1) connects reducing pipe (2), reducing pipe (2) connects trunnion (3), and trunnion (3) connects pre-dirt pocket (5), arranges spray nozzle (4) at trunnion (3) periphery；In cyclone dust removal part, cylinder (8) connects with pre-dirt pocket (5), and cone (7) is connected with cylinder (8), and cylinder (8) top arranges exhaustor (9).
Description
Technical field
The present invention relates to technical field of environment protection equipment, particularly for the cleaner unit processing dusty gas.
Background technology
Existing cyclone dust extractor is Application comparison one of cleaner widely in industry, and its dust removal mechanism is to make dust-laden
Air-flow rotates, and is separated by grit by means of centrifugal force and is trapped in wall, relend and help action of gravity to make dirt from air-flow
Grain falls into ash bucket.But this kind of cleaner unit is only suitable for processing the dust that particle diameter is bigger, for particle diameter less than the powder dust particle of 5 μm, goes
Except efficiency is the lowest.And for the gas containing fine dust, emission request to be reached, then need to increase two-stage dust removal and process technique,
Thus increase investment and floor space, also make operation, safeguard more complicated.
Summary of the invention
It is an object of the invention to provide a kind of cyclone dust extractor with pre-dedusting.
The present invention is a kind of cyclone dust extractor with pre-dedusting, has pre-dedusting and cyclone dust removal two parts, in pre-dedusting
Part, air inlet pipe 1 connects reducing pipe 2, and reducing pipe 2 connects trunnion 3, and trunnion 3 connects pre-dirt pocket 5, arranges spray at trunnion 3 periphery
Mist mouth 4；In cyclone dust removal part, cylinder 8 connects with pre-dirt pocket 5, and cone 7 is connected with cylinder 8, cylinder 8 top
Exhaustor 9 is set.
The present invention compared with prior art has the advantage that 1. existing dust removal efficiency in cyclone cleaners are low, especially
Particle diameter being less than to the powder dust particle of 5 μm, removal efficiency is the lowest.The cyclone dust extractor of the pre-dedusting of this band that the present invention relates to,
Water is from the spray nozzle ejection being arranged at trunnion, and the drop that the dust granules in air-flow sprays with spray nozzle at trunnion is tied mutually
Close, be mutually bonded after entering pre-dirt pocket, condense, increase, improve efficiency of dust collection by increasing dust size, particularly grain
Footpath is less than the removal efficiency of the powder dust particle of 5 μm.The most simple and compact for structure, easy to maintenance, floor space is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention, and Fig. 2 is the deflector sectional view of the present invention, reference and corresponding title
For: air inlet pipe 1, reducing pipe 2, trunnion 3, spray nozzle 4, pre-dirt pocket 5, disposal box 6, cone 7, cylinder 8, exhaustor 9, lead
Stream plate 10.
Detailed description of the invention
As it is shown in figure 1, the present invention is a kind of cyclone dust extractor with pre-dedusting, there is pre-dedusting and cyclone dust removal two
Point, in pre-dust removal part, air inlet pipe 1 connects reducing pipe 2, and reducing pipe 2 connects trunnion 3, and trunnion 3 connects pre-dirt pocket 5, at trunnion
3 peripheries arrange spray nozzle 4；In cyclone dust removal part, cylinder 8 connects with pre-dirt pocket 5, and cone 7 is connected with cylinder 8,
Cylinder 8 top arranges exhaustor 9.
As it is shown in figure 1, the described cyclone dust extractor with pre-dedusting, the top of pre-dirt pocket 5 is cylinder, and bottom is circle
Cone structure.
As shown in Figure 1 and Figure 2, the described cyclone dust extractor with pre-dedusting, pre-dirt pocket 5 is connected with cylinder 8, even
Logical place is provided with deflector 10.
As it is shown in figure 1, the described cyclone dust extractor with pre-dedusting, spray nozzle 4 at least includes 4, and symmetrical connection is in larynx
Pipe 3, the quantity of spray nozzle 4 determines according to handled dusty gas flow and dust content.
As it is shown in figure 1, the described cyclone dust extractor with pre-dedusting, disposal box 6 is connected to pre-dirt pocket 5 and cone 7
Bottom.
The work process of the present invention is: first dusty gas is entered reducing pipe 2 by air inlet pipe 1, and flow velocity is gradually increased, air-flow
Pressure can gradate as kinetic energy, in trunnion 3 porch, gas speed reaches maximum, water by symmetrical connection in the spraying of trunnion 3
Mouth 4 sprays into, and water droplet is by high-speed gas atomization and acceleration, in water droplet accelerator, due to inertial collision between water droplet and particle,
Realize the trapping of subparticle.After air-flow is entered pre-dirt pocket 5 by trunnion 3, speed reduces, and makes the cohesion with granule as the nuclei of condensation
Speed is accelerated, and forms the dust granules being relatively large in diameter, and part dust granules is deposited at the bottom of the cone of dirt pocket 5 under gravity
Portion, and enter disposal box 6.Dusty gas continues to be entered cylinder 8 by pre-dirt pocket 5, by deflector 10, along cylinder 8
Wall rotates from top to bottom, after the major part of swirling eddy arrives bottom cone 7, then upwards by exhaustor 9 row
Go out.When air-flow rotates, grit the most progressively shifts to barrel, arrives the grit of barrel at air-flow and weight
Power jointly acts on down and falling in disposal box 6 along wall.
