Description

Gasoline fractionator with particle separation function {GASOLINE FRACTIONATOR WITH PARTICLE SEPARATION FUNCTION}

The present invention relates to a gasoline fractionator, and more specifically, to a gasoline fractionator with a particle separation function that can smoothly separate and discharge coke particles contained in the gas to be treated.

In general, a gasoline fractionator recovers the heat of the gas released after decomposing naphtha in a decomposition furnace and recovers heavy fuel oil and gas oil. For reference, the naphtha refers to the oil distilled out of the distillation tower during the distillation of crude oil in a temperature range of 30 to 200°C.

In the process of decomposing naphtha in the decomposition furnace to produce ethylene, coke particles are generated as a by-product. Previously, the coke particles were collected and separated using a gasoline fractionator and a hydro cyclone.

However, as a separate wet cyclone device must be provided to separate the coke particles contained in the gas as described above, the structure of the device may become complicated, construction may be expensive, and maintenance may be cumbersome.

Accordingly, recently, additional structures such as baffles were added to separate coke particles contained in the gas supplied to the gasoline fractionator.

However, the baffle installed in the conventional gasoline fractionator can guide the gaseous fluid (hereinafter referred to as the gas to be treated) supplied inside through inlets provided opposite to each other on both sides of the interior along the inner walls on both sides of the baffle. However, this conventional baffle structure has the problem that the performance of separating coke particles in the fluid is inevitably reduced.

That is, the gas to be treated supplied into the main body through the two inlets is divided in both directions along the inner wall by the baffle, forming an upward and downward flow within the main body. The flows divided into two directions meet each other at the midpoint as they move along the inner wall of the body due to its structure.

At this time, the moment the two rising flows containing coke particles meet each other at the midpoint of the inner wall, the two rising flows quickly move upward, and the coke particles contained in the gas to be treated are not separated and escape upward along with the rising flow. Cases may arise. Accordingly, there is a problem that the performance of separating coke particles contained in the gas to be treated is reduced.

Figure 1 is a perspective view of a gasoline fractionator according to the present invention, Figure 2 is a plan view of a gasoline fractionator according to the present invention, and Figure 3 is a cross-sectional view taken along line II' of Figure 2 and the flow of the gas to be treated. This is a side view showing.

Referring to FIG. 1, a gasoline fractionator 1 according to a preferred embodiment of the present invention may include a main housing 110 and a baffle member 120.

A detailed description of the configuration of the present invention is as follows. For reference, in the present invention, for convenience of explanation, only the lower part of the gasoline fractionator 1 will be shown and described in the drawings.

First, the main housing 110 constitutes the main body of the gasoline fractionator 1, and may be formed in a hollow shape with a receiving space S provided therein. Additionally, an inlet 111 may be provided on the upper outer circumference of the main body housing 110, and an outlet 113 may be provided at the lower part of the main body housing 110.

Specifically, the main housing 110 may have a horizontal cross-section that is either circular or polygonal, such as a square, pentagon, or hexagon. Preferably, the main housing 110 has a circular cross-section so that a rotating flow can occur around the outer circumference of the receiving space (S) based on the vertical central axis of the receiving space (S) through the baffle member 120, which will be described later. can be formed.

Hereinafter, in the present invention, an example will be shown and described where the horizontal cross-section of the main housing 110 is formed in a circular shape. Of course, it is not limited to this.

Referring to FIG. 2, the lower portion 110a of the main body 110 where the outlet 113 is provided may be formed in a semi-elliptical shape with an inner diameter that gradually decreases.

Additionally, a plurality of the inlets 111 may be provided on the upper outer circumference of the main body housing 110 to be spaced apart from each other with respect to the central axis.

Preferably, the inlet 111 may be composed of at least one pair of which two are opposed to each other and arranged symmetrically around the central axis of the receiving space (S). In the present invention, an example will be shown and described where the inlets 111 are arranged to face each other as a pair. Of course, it is not limited to this.

The baffle member 120 is installed to correspond to the position of the inlet 111 on the inner peripheral surface of the main body housing 110. This baffle member 120 is supplied into the receiving space (S) through the inlet 111. It serves to generate a swirling flow by guiding the gas to be treated (A) in one direction based on the central axis.

Referring to FIG. 3, the gas to be treated, which is guided in one direction through the baffle member 120, swirls and flows along the inner peripheral surface of the main housing 110. At this time, the solid particles (P) contained in the gas to be treated rotate along the inner peripheral surface of the receiving space (S) by centrifugal force, and gradually move downward due to the density difference with the gas to be treated, and then exit the outlet ( 113) and can be separated and discharged to the outside (Cyclone particle separation principle).

That is, in the swirling flow of the gas to be treated, both the solid particles (P) and the gas are subjected to centrifugal force. At this time, the solid particles (P) are more affected by the centrifugal force than the gas. Accordingly, the solid particles (P) come into close contact with the inner peripheral surface of the receiving space (S), and while in such close contact, they can be smoothly moved and discharged toward the outlet 113 while rotating downward within the receiving space (S). .

In this case, the baffle member 120 may have a shape in which at least one side 121 is open so that the gas to be treated supplied through the inlet 111 can rotate and flow in one direction about the central axis.

In addition, the baffle member 120 may have guide wings 123 extending at one end of one side 121 along the direction of movement of the gas A to be treated so as to supply the gas A to be treated at a downward angle. .

Referring to FIG. 4, the guide vane 123 has a vertical partition wall (123a) spaced apart from the inner peripheral surface of the accommodation space (S) with a curvature corresponding to the accommodation space (S) at the top of the vertical partition wall (123a). It may include a horizontal partition 123b extending toward the inner peripheral surface.

In this case, the horizontal partition wall 123b may be formed to be inclined downward along the moving direction of the gas A to be treated. Therefore, the solid particles (P) contained in the gas to be treated (A) can be smoothly guided to the outlet 113.

That is, the guide wing 123 has a structure in which the upper side is blocked by the horizontal partition 123b and the lower side is open, and the guide wing 123 is supplied through the inlet 111 using the baffle member 120 provided. The gas to be treated (A) can be smoothly guided in one direction of the receiving space (S) to form a swirling flow.
In addition, the vertical partition 123a and the horizontal partition 123b may be formed to gradually narrow in width along the moving direction of the gas A to be treated.

In this case, in the present invention, an example of the case in which the gas to be treated (A) is rotated and flowed clockwise through the guide blades 123 is shown and explained, but the present invention is not limited to this and the guide blades 123 are rotated counterclockwise. Of course, it can be installed so that it extends in the direction and changed so that the gas to be treated (A) rotates and flows counterclockwise.

Referring to FIG. 5, in another embodiment, the inlet 111 rotates in one direction by the baffle member 120, that is, passes through the central axis in a plane perpendicular to the central axis of the receiving space (S). It can be installed to form a straight line and a predetermined angle (θ) to supply the gas to be treated. Therefore, when supplying the gas to be treated through the inlet 111, a swirling flow can be efficiently generated within the receiving space (S) together with the baffle member 120.

Referring to FIG. 6, inside the receiving space (S), a mesh is installed in the space between the inlet 111 and the outlet 113 to filter out particles of a predetermined size or larger contained in the gas to be treated. A grating member 130 may be provided.

That is, the grating member 130 allows only particles (P1) of a predetermined size or smaller to pass through and discharges them to the outside through the outlet 113, and filters out particles (P2) of a predetermined size or larger.

In this way, the discharge port 113 can be prevented from being clogged by filtering particles of a predetermined size or larger through the grating member 130. In addition, the filtered particles (P2) can be collected during periodic maintenance, and the collected particles (P2) can be used for a certain purpose.

In this case, the lower space S1 of the grating member 130 may be filled with liquid L, for example, quench oil, to a predetermined level.

That is, the solid particles (P1) gradually moving downward by the swirling flow through the baffle member 120 are mixed with the liquid (L) and then discharged together with the liquid (L) through the outlet 113, and the solid particles Some of the gas to be treated (A), which moves downward along with (P), can be fundamentally prevented from being discharged through the outlet 113 by the liquid (L) filled in the lower space (S1). .

In other words, only the separated solid particles (P1) can be discharged through the outlet 113, and the gas to be treated (A) from which the solid particles (P) are separated moves to the upper side of the main housing 110. do.

Then, the operating principle of the gasoline fractionator 1 with a particle separation function according to the present invention configured as described above will be explained again with reference to FIGS. 3 and 6.

First, the gas to be treated supplied to the receiving space (S) in the main housing 110 through the inlet 111 is a pair of baffle members 120 and guide wings ( 123), and thus generates a swirling flow within the receiving space (S) (see Figure 3).

The gases to be treated, each guided in one direction by the pair of baffle members 120, generate a swirling flow along the inner wall of the receiving space (S) without colliding with each other.

In this case, the gas to be treated in the swirling flow does not rise but tends to rotate along the wall. Accordingly, the solid particles (P) contained in the gas to be treated are rotated along the inner peripheral surface of the receiving space (S) by centrifugal force, and eventually move gradually downward due to the density difference with the gas to be treated (A) and then to the outlet. It can be separated and discharged through (113) (see Figure 6).

Meanwhile, the gas to be treated (A) from which the solid particles (P) have been separated through the above process can be manufactured into a desired product by moving upward and then undergoing a certain processing process.

Figure 7 is a comparison table comparing the performance of the gasoline fractionator of the present invention and the conventional gasoline fractionator.

Referring to Figure 7, the process was performed under the same conditions using a conventional gasoline fractionator and the gasoline fractionator 1 of the present invention.

As a result, when the solid particles (P) contained in the gas (A) to be treated were separated using the gasoline fractionator (1) according to the present invention, the separation efficiency was improved compared to when the conventional gasoline fractionator was used. You can see that

In the above, the present invention has been shown and described with reference to specific specific embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the technical spirit of the present invention.
