Abstract

The invention discloses a Z-shaped airflow rotary electrode plate electric dust remover with the higher dust removal efficiency. Based on an existing electric dust remover, the Z-shaped airflow rotary electrode plate electric dust remover is characterized in that a rotary positive electrode plate system capable of penetrating through dusty airflow is arranged, particularly, an inlet wind shield 14 and an outlet wind shield 13 are arranged on the front and back portions of a rotary positive electrode plate in a staggered mode, and therefore dusty airflow penetrates through the positive electrode plate at a short range in a crossed mode according to a Z-shaped path to improve dust removal efficiency.

Description

Z-type air-flow rotating polar plate electric dust collector

Technical field

The invention belongs to the electric cleaner field that environmental protection relates to.

Background technology

The positive plate of the electric cleaner of existing a large amount of use is fixing.Unload ash and adopt rapping mode, reentrainment of dust is serious, and deashing is not thorough.Create and positive plate is divided into lath 4 for overcoming this shortcoming and is contained on chain 3 and rotates, in bottom with grey brush deashing, inhibit reentrainment of dust, also can reach the object of the thorough deashing of positive plate, improve efficiency of dust collection.But generally when acceptable valency than, the discharge dust-laden of electric cleaner, at more than 50mg/m3, is the requirement being difficult to reach the New emission standard 10mg/m3 that will promulgate.

Summary of the invention

For improving efficiency of dust collection further, to be of the present inventionly contemplated that: rotate between each lath 4 on positive plate and form larger gas channel, be provided with import deep bead 14 in the inlet air side of electric field.Outlet deep bead 13 is provided with in air side.And import deep bead 14 and outlet deep bead 13 keep out the wind for rotating the gas channel dislocation layout formed along primary air direction between positive plate, this is forced to Z-type route through the passage rotated positive plate lath 4 with regard to making the overwhelming majority of dust-contained airflow, Charged closely passes crosswise apart from anode, and dust collection efficiency improves.

When rotating the lath 4 on positive plate and forwarding bottom to, adopt and be similar to cloth bag pulse system to the control of dust winding-up removing on lath 4, make positive plate deashing more thorough, do not produce inverse corona.Invention is expected to the discharge standard being issued to 10mg/m3 in the prerequisite being equivalent to old-fashioned electric cleaner cost performance.

Flow velocity when passing lath 4 to make air-flow is low, many with the low coverage chance of lath 4, the present invention designs and installs shape between lath 4 and chain 3 and have a certain degree, such as can select 30 °, 45 °, 60 °, 90 ° (i.e. vertical and chains 3), flow area is large so on the one hand, wind speed is low; The time of Charged and lath 4 closer distance is long on the one hand, chance is many, is conducive to positive plate dust suction.

Utilize air pulse nozzle 7, the control of dust removed on lath 4 is simple, reliable, but needs compressed air condition.The present invention designs and rotates positive plate lower end inside and arrange roller 5 in an ash brush identical with the gear wheel diameter that upper end drives positive plate to rotate for this reason, grey brush interior roller 5 garden side face establishes expired elastomeric finer wire and ensure after brush dust, recover former linearity.If desired a dead axle ash brush outer roller 6 is set at rotation positive plate lower end outside again, makes the more thorough of collection ash cleaning.

Detailed description of the invention

An electric field and multiple field operation can be selected according to concrete working condition.If the electric field before multiple electric field can select fixed positive plate form, last electric field selects the present invention program.Also design of the present invention can all be selected by each electric field in many electric fields.Add bracing frame with except the bearing of fixing rotation positive plate upper end runner except needing between electric field in this case, the deep bead between adjacent two electric fields can not be established, and one also can be established to share.When sharing, second, four electric fields are equivalent to import deep bead 14 and outlet deep bead 13 reversing of position to use.

Arrange in import deep bead 14, the upright electric cleaner of outlet deep bead 13, all to be connected as a single entity with shell body along the upper edge of deep bead on airflow direction and left and right side, as far as possible stuffy, lower edge will be inserted in the dust heap of ash bucket, to ensure the operating efficiency of deep bead.Certain space to be ensured between deep bead and rotation positive plate, touch less than deep bead when ensureing that lath 4 moves.In Fig. 3, A1, H1 are all greater than A, the H in Fig. 2, and A2, H2 in Fig. 4 all will be slightly less than A, H.

Rotation anode plate system and pulse dust cleaning system are mature technologies, can making and installation and maintenance routinely.

Cathode line 2 and the distance also existing fixed positive plate line space design of reference rotated between positive plate 4.Cathode line 1 can be added if desired above rotation outside, positive plate upper end, uniform to strengthen electric field.

When selecting roller 5 and grey brush outer roller 6 in the present invention's ash brush, in ash brush, roller 5 is due to without dead axle, by gravity passive rotation brush dust, may produce axial float phenomenon.Can in import deep bead 14 and ash brushs between roller 5, air outlet deep bead and grey brush to be all welded with block in addition spacing solution between interior roller 5.

The steel wire that ash is brushed on interior roller 5 and grey brush outer roller 6 must be anti-corrosion, and have good elasticity, and fine and soft with the shock adapting to lath 4.If outer roller deashing in selecting, then the length of brushing silk is the over half of lath 4 width.
