Problems solved by technology

[0002] At present, when welding or cutting workpieces with oil on the surface, a large amount of smoke and dust containing oil mist will be generated. If the smoke and dust containing oil mist are treated with ordinary dust collectors, the oil mist will adhere to the filter cartridge or cloth bag. Hardening is formed on the surface, which will quickly block the filter cartridge or bag, causing the pressure of the dust collector to increase, making the dust removal system unable to operate normally
[0003] At present, the main way to purify the smoke and dust containing oil mist is to add another powder supply device to the ordinary dust collector. Although this treatment method is simple to operate, it has the following disadvantages: First, the equipment occupies too much Second, powder spraying is unreliable, often causing blockage of filter cartridges or cloth bags, resulting in greater economic losses; third, when there is a lot of oil mist in the smoke, powder spraying alone cannot completely absorb oil mist and block oil. The mist is adsorbed on the surface of the filter cartridge or bag

Embodiment 1

[0026] see figure 1 and figure 2 , the pretreatment device for oily mist and dust in the illustration is a preferred embodiment of the present invention, specifically including a pretreatment box 3, an air inlet 301 is provided on the top of the pretreatment box 3, and an air inlet 301 is provided on the side wall of the box. A plurality of air holes 302, the oil mist smoke enters from the air inlet, and is discharged from the air holes 302. The bottom of the pretreatment box is conical, which is filled with a certain amount of dry talc powder 6, and a powder spraying assembly 5 is arranged above the dry talc powder 6 pile, which is used to spray the dry talc powder to form The dust is mixed with the oily mist entering the tank.

[0027] The interior of the pretreatment box 3 of the present embodiment is provided with a partition 303, and the partition 303 divides the inner chamber of the pretreatment box into an air inlet passage 304 and an air outlet passage 305 which com...

Embodiment 2

[0033] On the basis of embodiment 1, refer to image 3 and Figure 4 , a kind of oil mist fume purifier in the illustration is another preferred embodiment of the present invention, which includes two groups of dust removal devices 1 and the pretreatment device 2 in Example 1, wherein the pretreatment device 2 is arranged in the middle, The boxes of the two groups of dust removal devices 1 are fixed and connected side by side with the boxes of the pretreatment device, and the air holes on both sides of the pretreatment box are connected with the air inlet chamber of the dust removal device. Cartridge 102, the dust and oil mist coming from the air hole of the pretreatment box are filtered on the surface of the filter cartridge, and the filtered air is discharged through the air outlet connected inside the filter cartridge. The air inlet 301 of the pretreatment device 2 is The air inlet of the whole purifier, the air outlet 102 of the dust removal device 1 is the air outlet of ...

Abstract

The invention discloses a pretreatment device for oil mist and dust and a purifier for its application. The pretreatment device includes a pretreatment box, the bottom of the pretreatment box is filled with dry talc powder, and a spray nozzle is installed above the dry talc powder. Powder assembly; the cavity of the pretreatment box is divided into an air inlet channel and an air outlet channel through a partition, wherein, the top of the air inlet channel is connected with the air inlet on the box body, and the bottom end extends to the top of the dry talc powder, and the inside of the air inlet channel Several layers of oil mist filter plates are arranged; one end of the air outlet channel communicates with the bottom of the air inlet channel, and the other end communicates with the air hole provided on the outer wall of the pretreatment box. The oil mist fume purifier combines the pretreatment device with the dust removal device, and has a compact structure. The pretreatment device can filter out most of the oil mist in the smoke, and the remaining oil mist is absorbed by the talc powder pre-coated on the surface of the filter cartridge to prevent the oil mist from sticking. Attached to the surface of the filter cartridge of the dust removal device, it can ensure the normal operation of the dust removal system and prolong the service life of the filter cartridge.
