Problems solved by technology

[0003] The existing oil mist purification treatment methods are usually adsorption through filter screens or separation by electrostatic treatment devices. However, for fastener manufacturers, oil mist is relatively dense and there are many equipments. Traditional oil mist treatment It is difficult for the device to collect and purify the oil mist in the workshop, resulting in a poor workshop environment

Embodiment 1

[0047] Such as figure 1 As shown, the ventilation duct includes a plurality of branch pipes 2 and a single main pipe 3. One end of the branch pipe 2 is connected to the drainage mechanism, and the other end leads to the main pipe 3. At this time, the filter device 20 is arranged between the main pipe 3 and the electrostatic precipitator 30 During the period, the oil mist caused by the corresponding processing equipment 100 such as the tooth rolling machine is absorbed into the main pipe through the branch pipe through the suction mechanism, and then enters the filter device and the electrostatic precipitator through the main pipe for separation and purification. Only one filter device is used, and the The filter device and electrostatic precipitator can be installed outside the workshop, reducing the floor space in the workshop and making use of the layout of the workshop in a small space.

Embodiment 2

[0049] Such as figure 2 As shown, the ventilation duct includes a plurality of branch pipes 2 and a single main pipe 3, one end of the branch pipe 2 is connected to the drainage mechanism, and the other end leads to the main pipe 3, the filter device 20 is arranged between the branch pipe 2 and the main pipe 3, and A pipeline axial flow fan is added in the branch pipe 2. At this time, a single processing equipment 100 corresponds to a single filter device. The added axial flow fan is used to improve the suction effect and avoid the problem of insufficient suction force caused by the addition of multiple filter devices. Through a single The processing equipment corresponds to the setting of a single filter device, which can effectively improve the purification effect of oil mist, and can greatly reduce the deposition of grease in the main pipe and reduce the cleaning work of the main pipe. It is suitable for workshops with large space and many production equipment.

Abstract

The invention discloses an exhaust gas treatment system, comprising an air suction device, a filter device and an electrostatic dust removal device. The air suction device includes a drainage mechanism, a ventilation duct and an induced draft fan. The drainage mechanism is connected with the ventilation duct, and the suction The fan is used to provide wind power to suck the exhaust gas from the drainage mechanism into the ventilation duct. The drainage mechanism includes a cover body. The filter device is arranged behind the drainage mechanism and communicated with the drainage mechanism. The filter device includes a housing, a primary filter screen , adsorption mechanism, lifting mechanism, the primary filter screen and adsorption mechanism are arranged inside the casing, the lifting mechanism is arranged on the upper part of the casing and can drive the adsorption mechanism to move vertically up and down, the head and tail sides of the casing have The opening is communicated with the ventilation duct, and the electrostatic precipitator is arranged behind the filter device and communicated with the filter device. The invention is suitable for the purification treatment of oil mist waste gas generated by metal processing, and effectively protects the ecological environment.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a treatment system suitable for oil mist waste gas produced in metal processing. Background technique [0002] During metal processing such as turning, milling, drilling, grinding, etc., due to the use of metal cutting fluid, a large number of oil mist particles will be formed in the air. Metal processing lubricants are a very complex mixture. In addition to containing hydrocarbons In addition, it may usually contain various chemical substances such as sulfonates, fatty amines, nitrates, dyes, and fungicides. If it is a lubricant that has been put into use, due to the oxidation of hydrocarbons, the reproduction of microorganisms or the pollution of external impurities, the metal processing lubricant may contain more chemical substances that are harmful to the human body and the ecological environment. Therefore, controlling the concentration of oil mist in metal processing wor...
