Abstract

PURPOSE:To separate splash liquid droplets in good efficiency in a state hardly receiving the influence of the inflow speed of a gas and a particle size, by a method wherein a gas containing splash like liquid droplets is sent into a vortex shaped flowline and liquid droplets are separated by centrifugal separating action and a liquid droplet impinging and receiving plate. CONSTITUTION:A gas is sent into a vortex shaped flowline 22 from each gas inflow pipe 7 through the inlet part 20 of a vortex forming body 6 to be fallen in a revolved state. At this time, splash like liquid droplets are gathered and adhered to the curved inside wall surface of a vortex shaped surface by the action of centrifugal force and directed to a lower bottom plate 23 by gravity. The radius of curvature and the cross sectional area of the vortex shaped wall are gradually reduced and converged and liquid droplets are made susceptible to separation due to strong centrifugal force. The flowed-down separated liquid is collected by a separated liquid collecting member 27 and impinged to a liquid droplet impinging and receiving plate 8. The gas stream is impinged to the inside surface of the vortex shaped wall 21 to separate residual liquid droplets and further injected toward a hollow barrel part 14 from a gas emitting gap part 26.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method and method for separating and removing droplets from an airflow in a tube Il [6] containing droplets by using centrifugation, aggregation, and collision. Concerning vessels.

This divine gas-liquid separation method and separator are used in many industrial fields including the chemical industry.

When gas containing microscopic droplets (hereinafter referred to as droplets) of mist (hereinafter referred to as droplets) and drain flows through a pipe, the droplets aggregate with each other and become drain, which can cause the flow of water in the pipe. They gather in low areas and flow down with the airflow.At this time, if the gas flow velocity is high (approximately l, m/Se C
The above-mentioned drain, which collects at the lower part of the flow path and flows down, is again turned into droplets due to the flow rate of the gas in the pipe, and flows down with the airflow. Some droplets are difficult to undergo sedimentation due to gravity in a gas, making it difficult to perform gas-liquid separation, making it difficult to effectively remove and discharge the droplets. There are various means for separating particles in an air stream, and their gas-liquid separation effects are based on the following basic principles, which are applied either singly or in combination. many. Namely, (1) gas-liquid separation by gravity sedimentation.

(2) Collision into droplets and gas-liquid separation.

(3) Air separation by centrifugal force separation and droplet formation accompanied by agglomeration.

(4) Gas-liquid separation due to sudden 4C direction change of airflow using type J louvers.

etc.

Some conventional gas-liquid separators based on the principle of operation described above have features such as a simple structure and low pressure loss within the device. There is a tendency for separation equipment to become larger, separation capacity is lower due to droplet droplets (i & k for small droplets), and avoidance of larger separation equipment as described above. However, when miniaturization is achieved, some problems remain, such as the separation ability not deteriorating when the gas flow rate increases.

Therefore, when selecting an existing gas-liquid separator, for the reasons mentioned above, certain function-1 problems cannot be ignored.

In addition, the discussion is different based on specific examples. There is a Nanto type F→]f device that removes droplets, which is shown in Figure 7.
As shown in Figure 2, an inflow pipe a1 and an outflow port C are provided at 1:6 symmetrical positions in a part of I part of the Kasuri-shaped separation tank b, and between this inflow pipe f1 and outflow pipe C, A baffle plate d that connects the side 0 to the lower MRa so as to block the
is suspended from 14 parts of the separation tank 1), and a partition plate f with a notch communicating with the drain pipe g is attached between it and the side part 0 at a distance of about 1 hour. , inflow origin・8
The gas and liquid are separated by the collision force when the gas containing droplets sent from λ is forced into the panful plate d and the inertial force when the direction is changed by the partition plate f', and the gas is transferred to the gas outflow pipe C. How many droplets are sent out from the separation tank b and land on the inner wall of the separation tank b or the panful plate d? Although it has the advantage of having a simple structure and low pressure loss, it requires a relatively large space for the outside of the gas and liquid compared to other methods, and the installation H1 volume hf
At the actual inflow velocity near the L limit side that appears to be, the minute A1 [
Some of the droplets in the tank l) are turned into droplets again by the airflow, and together with the airflow, gas θ;
Further, in this method, droplets such as mist in the gas flow together with the gas without being sufficiently aggregated into droplets, which poses problems in terms of gas-liquid separation and removal.

In addition, various shapes of cyclone separation 'tK using centrifugal separation have been put into practical use.For example, in the shapes shown in Figs. 3 and 7, the body part 1) has a circular shape. An uneven hollow circular phloem 0 is integrally formed on the lower side of the body, and a separated liquid extraction port ■Yo is provided at the lower end of the body. A bottom plate is formed on /:ja, and one exhaust pipe is located in the center of the bottom plate, and the lower side is connected to the body part I (
A gas inflow pipe A is arranged so as to surround the body part 13 along the outer peripheral wall on the upper side of the body part 13, and this gas inflow pipe A is It is connected to the body part 13 so as to circulate the airflow in the body part B (1'4 configuration), and when a few drops of gas are blown into the body part F3 from the gas tube A, this The airflow inside the body part B turns into a downward swirling flow shown by Ek'+, and descends without turning, reaches near the lower end of the hollow circular shell 8 part C, and reverses. It becomes an ascending swirling flow, swirls upward, and is exhausted through one exhaust pipe.On the other hand, the droplets separated due to the swirling, reversal, etc. of the airflow are discharged from the separated liquid discharge 01° at the bottom of the hollow conical part C. In order to evaluate the separation ability of this cyclone separator, there is a concept of 1=o% captured average particle size. In this case, droplets that are so small that they cannot be sufficiently centrifuged in the body of the cyclone separator are left unremoved by the minute mfff along with the gas. It is discharged after passing through the cyclone km/kw.

However, the amount of droplets flowing out without being separated in the cyclone separator also depends on the inflow rate of the gas containing the droplets flowing into the cyclone separator, and the rate of gas inflow or the set speed is If it exceeds , the proportion of droplets flowing out of the cyclone separator through the exhaust gas @D will increase.
As shown in Fig. 7, this means that the upward swirling flow F toward the entrance of the exhaust pipe near the entrance of the exhaust pipe becomes larger.
At this time, droplets of minute size that have not been sufficiently subjected to centrifugal separation within the body part B or short-circuit flow 5'' are generated as described above.
This is to ride the ascending flow.

Also, even if the inflow velocity of gas into the cyclone separator becomes lower than the designed velocity, the amount flowing out into the droplet liquid layer or the exhaust stack will increase, or will this be due to the separation effect mainly due to Xr centrifugal force? From these facts, it can be seen that the application of the cyclone type gas-liquid separator to cases where the air flow velocity within the pipe is subject to large changes is inconsistent.

A wide variety of investigations and research have been conducted on the operating theory that affects the function of cyclone separators, and as a result, the theory and its application methods have been clarified. The opinions regarding this are also based on the research results of these theories of operation. In short, the speed of gas inflow to the cyclone separator
If the J value is too low or too high, the capture rate will deteriorate, and in general, the capture rate will deteriorate if the J value is too low or too high.

Therefore, it is necessary to change the size of the body diameter in accordance with the size of the average particle size to be captured.

To explain these functional characteristics from the perspective of structure H, the gas inflow pipe A is connected to the body part 13 that generates centrifugal separation and is inserted into the body part B concentrically. Although the structure of a typical cyclone separator is extremely simple, in which an exhaust pipe is provided and a hollow conical part C is connected to the lower part of the body part B, on the other hand, the body part B
The inlet of the gas inlet pipe A and the inlet of the exhaust pipe are directly adjacent to each other, and the downward swirling flow IE in the body part B and the hollow conical part C is located closer to the outside. There is no structure intervening between the center and the ascending swirling flow F, and the structure is also directly adjacent to the center, and these are the factors that cause the deterioration of the gas-liquid separation function as described above. It is also accompanied by

As mentioned in Section 2, although conventional impingement separators and cyclone separators have structures that are relatively easy to install in pipelines, they also have disadvantages in terms of droplet separation and removal based on their respective structures. It has functional weaknesses.

This invention was made in view of the above-mentioned drawbacks in the conventional embodiments, and the purpose of the invention is to:
Compared to the cyclone method or collision method, this method is less susceptible to the effects of gas inflow velocity and particle size, resulting in better separation efficiency, and allows the separator to be smaller for the same processing capacity. An object of the present invention is to provide a method and a separator for separating and removing droplets.

The gist of the method of the present invention is to send gas containing droplets into the spiral flow path from the inlet of the spiral flow path formed at the upper part of the spiral shaped body installed in the separation tank main body. When the gas moves through this spiral flow path, droplets are collected on the curved inner surface of the wall of the spiral shape by centrifugal separation, causing gas and liquid separation, and the spiral flow is The cross-sectional area of the road gradually decreases as the airflow advances, promoting the aggregation of droplets in the airflow, and by reducing the radius of curvature, they are less susceptible to the separation action of centrifugal force, resulting in centrifugal separation from the airflow. The separated liquid flows down along the inner surface of the outer wall of the spiral flow path, is collected, and collides with the droplet collision receiving plate, while the air flow flows against the spiral wall near the end of the spiral flow path. This separates the droplets remaining in the airflow and causes them to collide with the droplet collision receiving plate through the spiral wall, and these separated liquids enter the notch in the partition plate of the lower blade of the separation tank main body. The airflow is discharged from the bottom of the separation tank main body by changing its direction and flowing out into the bottom of a wide cavity inside the separation tank main body.
The method of this invention separates gas and liquid by evacuation from the upper part of the separation tank main body. The gist is that two spiral bodies, which are formed by moving a spiral curve on a plane in a direction perpendicular to this plane, are placed side by side in the separation tank body, and the spiral directions of these spiral bodies are mutually aligned. At the same time, the wall surfaces of the respective inlet portions are arranged back-to-back with each other so that the spiral portions face each other on both sides, and the artificial portions are made to face above the peripheral wall of the separation tank main body. A droplet collision receiving plate that guides the separated liquid is installed at the bottom of the spiral shaped body in the separation tank body, and a partition plate that separates the separated liquid and the gas is separated. A notch is provided below the tank body and the partition plate is provided with a notch through which the entire separated liquid flows down;
A discharge sparrow 1 for discharging this separated liquid is connected to the lower end of the separation tank main body, and a gas outflow pipe is attached to the opposite side of the gas inflow pipe of the separation tank main body, and this gas outflow pipe and the spiral shape A plurality of baffle boards are provided in the cavity inside the separation tank body between the main body and the main body of the separation tank.

It flows down into the separated liquid chamber // from a and the vent hole /2, and is stored and discharged in the same way as the combined separated liquid.

Since the structure and operation of the present invention are as described in 1-6 below, the following effects are exhibited.

(1) Since droplets are centrifugally separated using a spiral body, it has a centrifugal acceleration effect similar to that of the hollow conical part of the cyclone Alff1 rl. The separation liquid progresses sequentially as it flows downward, and during this period, the separated liquid does not diffuse into the airflow and flow out into the gas outflow pipe.

(2) Since the structure has two spiral shaped bodies built into the separation tank body for the purpose of dividing the incoming airflow into two and centrifuging them, the outer dimensions of the separator are smaller than other cyclone separation methods. Despite its small size, its centrifugal separation effect is large.

(3) Since the incoming gas is divided into two parts for processing, the spiral shape body can be made smaller, and therefore the volume occupied within the separation tank body is reduced, and the volume of the cavity inside the separation tank body can be reduced. can be taken significantly. This prevents droplets that have been separated into gas and liquid at the droplet collision receiving plate from being remixed by the air current. (4) The liquid layer centrifuged inside the spiral body is collected in the separating liquid collection member. After that, the droplet is guided into the separated liquid conduit and reaches the droplet collision receiving plate, and the separated liquid does not collide with the spiral wall in the narrow part of the spiral flow path near the center of the vortex, so the separated liquid is re-spattered. Therefore, a high gas-liquid separation effect can be ensured.

(5) The spiral flow path in the spiral shaped body is interrupted by the force at the inlet and the product decreases as it moves toward the center of the vortex. In addition to increasing the diameter and forming liquid droplets that are susceptible to centrifugal separation, the airflow velocity is accelerated and centrifugal force is also increased, which improves the separation of droplets.

(6) Spiral channel and gas lA for centrifugal separation
The part of the discharge tube is divided by a spiral wall that forms a spiral shape, and does not cause short-circuit flow between them.
Since it is a single structure, there is no phenomenon in which fine droplets in the inner region of the swirling airflow transfer to the short-circuit flow and flow out into the gas outflow pipe, which occurs in the cyclone separation method. Therefore, the gas-liquid separation efficiency is high (7) The part where the gas-liquid is separated and the separated liquid is finally discharged is located near the bottom of the separation tank body.
6, diagonal 1. Since it is separated by a full height from the gas outlet pipe in the opposite direction, droplets will not be mixed into the outflow airflow again.

(8) The airflow after the separated liquid is removed is first introduced into the wide cavity inside the separation tank body, so the airflow velocity in this area is not high, so the droplets are carried back into the airflow. Never.

(9) The droplets separated from the airflow are immediately separated into separated liquid in the separated liquid chamber below the partition plate.
There is no possibility of re-mixing into the airflow that rises obliquely and flows out.

(10) The separated liquid collected in the separated liquid conduit collides with the inclined droplet collision receiving plate and then flows down into the separated liquid chamber. is captured by the edges and prevented from becoming droplets and being reintroduced into the airstream.

(TI),! Since the droplet collision receiving plates are symmetrically arranged to have inclined surfaces in opposite directions, when the separated liquid flows into the separated liquid chamber, it rotates around 11qll·t of the separated liquid chamber. No movement. For this reason, there is no risk of creating a cavity due to vortex flow in the upper part of the discharge in the center.

This invention is not limited only to the description and illustrations of the embodiments described above, and can be implemented with various changes and modifications without departing from the technical idea of the invention.

[Claims] (1) The airflow containing droplets is sent into the tapered spiral flow path formed in the separation tank body and has a downward slope, and is swirled downward while reciprocally agglomerating the droplets and centrifuged. The separated liquid is separated from the air stream by force, and the separated liquid is caused to flow down along the spiral flow path, and then collected and collided with the droplet collision receiving plate. The droplets that remain in the airflow are separated by colliding with the spiral wall near the end 'fW part 4J of the path, and the separated liquid is allowed to flow down along the spiral wall. By colliding with the plate, the liquid is merged with the separated liquid, and the combined liquid is allowed to flow down to the bottom of the separation tank body through the droplet collision receiving plate and discharged to the outside. A method of separating and removing a few droplets in the airflow by letting it flow into a wide cavity inside the separation tank body and then exhausting it from above.
