Description

Oil mist collector {Oil mist collector}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oil mist dust collector, and more particularly, to an oil mist dust collector having a multi-stage separation process that is performed in a different manner so as to more efficiently separate and discharge oil and air contained in oil mist generated in various industrial sites And the discharge of clean air can be induced.

Generally, an oil mist dust collector is a device configured to separate air and air separately by sucking air, that is, oil mist, containing a large amount of oil particles generated in various industrial sites or restaurants. At this time, the discharged oil can be collected and recovered separately and can be recycled. Since the cleaned air can keep the working environment fresh, the utilization of the oil mist is very high, so that the oil mist dust collector is used in various industrial fields.

Conventional oil mist dust collectors can be roughly divided into filter filtering method, centrifugal separator and electrostatic separator type dust collector. The dust collector of the filter filtration type is the most general type of dust collector, and a blowing fan and a filter filter are installed in the body to suck the oil mist, filter the impermeable oil particles by the filter, and discharge only the purified air. However, in order to exhibit a high filtration efficiency, the filter has to be frequently replaced, which is uneconomical in terms of maintenance cost.

The centrifugal dust collector is configured to separate the oil and the air by centrifugal force by forming a rotating air flow using a centrifugal separator. Since the shape and configuration of the centrifugal separator can be differentiated according to the nature of the separation object, it is necessary to develop a most suitable and efficient configuration. On the other hand, the centrifugal separation method can lower the maintenance cost as compared with the above-mentioned filter filtration method, but the filtration efficiency is also lowered, so that the fine particles can not be separated.

In addition, the dust collector of the electrostatic force separation type is configured to charge the oil mist to agglomerate and separate the oil particles. In general, the dust collector may be used together with the filter filtration method or the centrifugal separation method.

Meanwhile, in recognition of such a problem as described above, the present invention has been well known in the art, which is a dust collector having the centrifugal separation method and the filter filtration method together.

In this regard, in brief, when constructing the interior of the main body, a blowing fan is installed at the upper part and the lower part, respectively, and the oil mist is centrifuged at the lower part, and the filtered air is filtered after being filtered by the upper part.

However, due to the structural limitations of the internal components, there is a problem in that a smooth flow of airflow is not formed between the lower part and the upper part, resulting in the installation of more than one blowing fan.

In addition, since the motor for driving the blowing fan is directly exposed to the flow path of the air flow, there is a problem that the service life of the device can be shortened due to the oil being adsorbed, etc., Development is urgent.

To this end, the oil mist dust collector 100 includes a inlet cover 10 having a hollow protruding from the outer surface thereof to provide an entry path to the oil mist in the atmosphere, and having a hollow inside thereof; The position of the foam filter 20 and the alignment of the impeller 40 can be induced by being coupled with the inlet cover 10 so that the collision separation and the centrifugal separation can be sequentially performed in parallel so that the oil mist in the vaporized state can be liquefied A separation induction housing (30) for inducing the conversion of the air into the air; A body 60 disposed closely to the rear end of the separation induction housing 30 and providing a hollow inner space shielded from the outside so that the spiral rotation of the oil mist can proceed; A driving motor (not shown) for filtering the oil mist introduced from the inlet cover 10 by acting as a power source which can be fixedly coupled to the impeller 40 in the inner space of the body 60 to induce unidirectional rotation of the impeller 40 70); A filter member 81 which is accommodated in a space inside the rear end of the body 60 to filter the oil mist again and a rear end of the body 60 is sealed from the outside, A collecting part 80 divided into a cover body 82 including a cover 83; And a water collecting tank 90 located at the bottom of the body 60 and collecting the oil sludge generated from the separation induction housing 30 and the oil sludge generated from the body 60 through the induction pipe 91.

The inlet cover 10 is a constituent element in which the oil mist is initially introduced, and is not given an identification number, but a hollow protruding forward as shown in the drawing is formed to enable a more intensive suction efficiency to be realized.

The inlet cover 10 covers the front surface of the separation inducing housing 30 via the foam filter 20. The mutual coupling of the inlet cover 10 and the separation inducing housing 30 can be made by various known fastening means including a toggle clamp It is self-evident.

Preferably, the foam filter 20 is a component that is provided for resistive force against the oil mist introduced through the inlet cover 10 to be collided and separated, and is fixedly mounted on the rod end of the separation induction housing 30.

Here, the foam filter 20 is a kind of diesel particulate filter, which is formed by molding ceramics into a foam and used as a filter, which is also advantageous for prevention of infiltration of fine sludge.

The impeller 40 is an element for guiding the centrifugal force to be executed as the centrifugal force is transmitted to the oil mist while being rotated due to the rotational force of the driving motor 70.

The impeller 40 of the present invention is inserted into the space of the annular protrusion 32 of the separation induction housing 30 while being fixed on the center axis of the driving motor 70, The induced centrifugal force can be concentrated on the inner wall of the annular protrusion 32 located at a close distance therebetween, thereby inducing the oil mist in the vaporized state to be converted into the liquefied state.

The impeller 40 is well known in the art, however, in the present invention, the fixing position of the impeller 40 is specified, thereby maximizing the dust collecting efficiency. Hereinafter, detailed description will be given with reference to the drawings.

The collecting portion 80 may be divided into a filter member 81, a cover member 82 and a discharge port 83. The rear end of the body 60 is covered with a sealing member .

At this time, the filter member 81 can be employed as a Saran filter including a HEPA filter, a sludge filter, and the like.

For example, the High Efficiency Particulate Air Filter may be subjected to the filtering operation by the foam filter 20 and the centrifugal separation by the impeller 40 and the coil induction unit 50, , It is possible to collect particles having a size of 0.3 mu m up to 99.997%, so that a highly efficient filtration function can be exhibited.

3, the separation induction housing 30 shown in FIG. 3 includes a rod 31 extended to the tip for interposition of the foam filter 20, And an annular protruding portion 32 for covering the outer circumferential portion of the impeller 40 while maintaining the same clearance therebetween.

This configuration is advantageous in that the oil mist sucked through the inlet cover 10 is separated from the oil sludge to the annular protrusion 32 due to the impact separation by the foam filter 20 and the centrifugal force acting on the oil mist during rotation of the impeller 40 Concentrating centrifugal separation process.

That is, as shown in FIG. 4, the oil mist passing through the foam filter 20 contacts the inner wall of the annular protrusion 32 due to centrifugal force generated from the rotational force as it comes into contact with the impeller 40, which continues to rotate in one direction. And the annular protrusions 32 are collected and flowed into the water collecting tank 90.

The annular protrusion 32 may be provided in various shapes depending on the amount of oil to be collected or the installation place, as illustrated in FIG.

5 is a cross-sectional view showing that the configuration of the annular protrusion 32, which is a substantial part of the present invention, can be variously applied. As shown in Fig. 5, the annular protrusion 32 in the present invention has a circular cross section , Or a polygonal cross-section, thereby achieving the intended purpose. At this time, the polygonal section includes triangular, square, and the like.

The water collection tank (90) is disposed at the bottom of the separation induction housing (30) and the body (60) and includes a foam filter (20); Impeller 40; A coil swirl induction unit 50 to be described later; And the oil particles derived from the filter member 81 are recovered.

For example, the oil particles collected by the separation inducing housing 30 and the impeller 40 are concentrated toward the perforated area of the bottom of the annular protrusion 32 and fall toward the water collecting tank 90, The oil particles collected while passing through the coil swirling unit 50 and the filter member 81 are caused to communicate with the water collecting tank 90 by using a predetermined induction pipe 91 to recover the oil. For this, a through hole should be formed in the bottom of the body 60 so that the induction tube 91 can be drawn in, and a proper space for accommodating the induction tube 91 is drilled on one side of the water collection vessel 90 do.

Reference numeral 84 denotes an exhaust duct. The exhaust duct 84 has an upwardly bent shape so as to induce smooth discharge of purified air while being coupled with an exhaust port 83 of the collecting unit 80, It is self-evident.

According to the present invention, the coil swirling induction unit 50 is further interposed between the impeller 40 and the drive motor 70.

This configuration induces the same rotation of the impeller 40 and the coil swirl induction unit 50 through the driving power source of the driving motor 70 so that the oil mist which has not been liquefied by the centrifugal separation performed from the impeller 40 is re- (60).

The coil swirling induction unit 50 includes a number of penetration portions 51 through which the flow of the oil mist is centrifuged by the impeller 40, (52) for inducing a concentrated path of the oil mist to the penetration portion (51) along with the occurrence of a swirling phenomenon due to the reduction of the traveling speed of the oil mist, And a plurality of guide vanes protruding in the direction of the drive motor 70 on the boundary line between the penetration portion 51 and the extension portion 52 so as to induce spiral rotation of the oil mist introduced from the penetration portion 51 53).

As shown in the drawing, the penetration part 51 is divided into three parts, and the means for moving the penetration part 51 to the space of the body 60 by providing the movement path for the oil mist sucked through the impeller 40 do.

The extending portion 52 has a function of cutting off the traveling path of the oil mist and concentrating the traveling path of the oil mist to the region of the penetrating portion 51 by correspondingly segmenting the penetrating portion 51 do. At this time, the flow of the oil mist is suppressed by the extension portion 52, and naturally the vortex is generated in the corresponding region. As a result, the oil mist stays instantaneously in the space between the impeller 40 and the coil induction unit 50 It is possible to further increase the filtration efficiency. In particular, by giving an artificial rotational force to the oil mist moving into the body 60 depending on the penetration portion 51 The spiral centrifugation on the desired body 60 can be induced.

That is, the adoption of the penetration portion 51 and the extension portion 52 is a means for adjusting the oil mist through the impeller 40 to be indiscernible and excessively prevented from going straight into the body 60, ) Is used as a means for actively inducing the spiral turning with respect to the oil mist which is focused on the oil mist. To this end, in the present invention, a predetermined guide vane 53 is further provided on the boundary line between the penetrating portion 51 and the extending portion 52.

It is preferable that each of the guide vanes 53 has a rounded shape in the center direction of the body 60 and the protruding range in the direction of the drive motor 70 is the same as the width of the penetrating portion 51 .

That is, in order to induce stronger helical rotation with respect to the oil mist moving through the penetration portion 51 due to the characteristics of the coil swiveling induction unit 50 that rotates in conjunction with the rotational force of the drive motor 70, And the protruding length of the guiding vanes 53 should not be excessively excessive or too small as necessary.

For example, a single disk is provided to form the coil swirl induction unit 50, and the edges are evenly cut with a certain gap to induce generation of the penetrating portion 51 and the extending portion 52, It is also possible to induce generation of the lead vanes 53 proposed by the present invention.

According to the present invention having the above-described configuration, it is possible to more efficiently induce the discharge of clean air due to the multi-step separation process executed in a different manner, The centrifugal separation method is carried out in parallel and the filtration efficiency and oil recovery rate from the oil mist are further maximized.
