Specific embodiment

In Fig. 1 ~ 4, a kind of workshop dust-extraction unit, the first supervisor 1 connect with dirt pocket 2, dirt pocket 2 and the second supervisor 3 Connection, the second supervisor 3 connect with blower 4, and blower 4 is connect with air-exhausting duct 5；

Multiple branch pipes 6 are equipped on the first supervisor 1, the end of branch pipe 6 is equipped with wind-collecting cover 9；

The dirt pocket 2 is the confined space of at least 1 cubic metre or more of inner space, is equipped in confined space for extending The baffle 22 in the path of wind.The workshop less for particle content in dust cooperates the structure of baffle 22 by dirt pocket 2, It has been enough that air is made to reach discharge standard, wherein air velocity slows down in the position of dirt pocket 2 because internal diameter becomes larger suddenly, Particulate matter is easy to land under the obstruction of 22 structure of baffle, to realize the effect of purification.In preferred scheme such as Fig. 3, Adsorption layer 23 is equipped on 22 surface of baffle.For example, the adsorption layer 23 in this example uses flannelette, due to the particle owner in the application It, can be because friction generates electrostatic, to be attracted on flannelette in particulate matter and flannelette collision process if organic plastics.

In further preferred scheme, electrostatic precipitator 24 is additionally provided in dirt pocket 2.Due to the particle in the application If owner's plastic grain, therefore extraordinary effect, common electrostatic precipitation dress can be obtained using electrostatic precipitator 24 It sets 24 voltages and is up to 60000V, and in this application, the voltage according to different operating conditions or particulate matter index, in the application Only need 500 V ~ 10000V.It is further preferred that being usually arranged as 3500 V ~ 5000V.Electrostatic precipitator 24 in this example For the prior art, including electrode plate with holes, electrode plate is passed into high-voltage electricity, and the inner wall of dirt pocket 2 is grounded, and constitutes electrostatic field Play dust removing effects.

In preferred scheme such as Fig. 3, the baffle 22 be it is multiple, be equipped at least two in the upstream of electrostatic precipitator 24 A baffle 22, two 22 interlaced arrangements of baffle are at labyrinth structure；Upstream and downstream in this example is to be subject to air-flow direction.Fan In palace structure such as Fig. 3, the purpose of overall plan is to extend the path of wind path, increases the number of wind path turnover.

It is equipped at least one baffle 22 in the downstream of electrostatic precipitator 24, the second supervisor is at least blocked in the projection of baffle 22 3 entrance.Thus structure further increases the effect of absorption.

Preferred scheme such as Fig. 2, in 4, cyclone dust collectors 10 are additionally provided on the first supervisor 1.Thus structure can remove Greater particle size particulate matter and the heavier particulate matter of specific gravity in dust, such as the grains of sand.
