Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spherical cyclone for separating solid or liquid particles suspended in a gas into a clear gas and particles.

[0002]

2. Description of the Related Art Generally, a cyclone is known as a device for separating solid or liquid particles suspended in a gas into a clear gas and particles. Hereinafter, a conventional example of a cyclone will be described with reference to the drawings. 5 is a front sectional view showing a conventional example, and FIG. 6 is a plan view showing the conventional example.

As shown in FIGS. 5 and 6, the cyclone B includes a main body 101 for separating gas and particles, an introduction pipe 102 for introducing a gas containing particles into the main body 101, and a main body 10.
A discharge pipe 103 for discharging the gas separated from the particles in the main body 101 to the outside of the main body 101 and a discharge pipe 104 for discharging the particles separated from the gas in the main body 101 to the outside of the main body 101. The main body 101 includes a cylindrical upper portion 101a and a conical lower portion 101b.

The gas containing the particles introduced into the main body 101 from the introduction pipe 102 descends while swirling along the inner wall of the upper part 101a, and during this, centrifugal force acts on the particles so that the particles are directed toward the wall of the upper part 101a. And is separated from the air flow. The separated particles descend along the inner wall of the lower portion 101b and are discharged from the discharge pipe 104 to the outside of the main body 101. The swirling diameter of the gas separated from the particles became smaller in the lower portion 101b, and an ascending air current was generated in the center, and was led out from the outlet pipe 103 to the outside of the main body 101.

[0005]

However, the above-mentioned conventional techniques have the following problems. Since the body of the cyclone consists of a cylindrical upper part and a conical lower part, it becomes a vertically long shape and the body cannot be made compact.
In addition, a swirling flow is generated in the upper part of the cylindrical shape to centrifuge the particles, but since the upper part is in the cylindrical shape, a pressure loss is large and a blower with a large air volume is required.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a compact spherical cyclone that functions as a blower having a small pressure loss and a small air flow.

[0007]

In order to solve the above problems, the present invention provides a cyclone for separating particles suspended in a gas into the gas and the particles, wherein the cyclone main body is formed into a spherical shape. Constructed a spherical cyclone.

[0008]

[Operation] According to the present invention, the gas containing particles descends while swirling along the inner wall of the main body, during which centrifugal force acts on the particles, causing the particles to move toward the wall of the main body and move from the air flow. To be separated. Moreover, since the air flow becomes a spiral spiral flow that descends while swirling in a spiral shape, the pressurization loss becomes small.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 of the drawings is a front sectional view showing an embodiment of the present invention, FIG. 2 is a plan view showing an embodiment of the present invention, FIG. 3 is an explanatory view of a case where a spray nozzle is provided in the embodiment of the present invention, and FIG. FIG. 3 is an explanatory diagram when a cooling and heating coil is provided in the embodiment of the present invention.

As shown in FIGS. 1 and 2, the spherical cyclone A comprises a spherical main body 1 for separating gas and particles, an introduction pipe 2 for introducing a gas containing particles into the main body, and a particle in the main body 1. A lead-out pipe 3 for leading the gas separated from the main body to the outside,
A discharge pipe 4 for discharging the particles separated from the gas in the main body 1 to the outside of the main body 1.

The main body 1 has a two-divided structure which is halved from the center, and comprises a hemispherical upper portion 1a and a hemispherical lower portion 1b, and a ring-shaped collar portion projecting outward at the opening end of the upper portion 1a. 1c is formed, and a ring-shaped collar portion 1d protruding outward is formed at the opening end of the lower portion 1b. To attach the upper portion 1a and the lower portion 1b, the collar portion 1c and the lower portion 1c of the upper portion 1a are mounted.
Insert a ring-shaped packing between the flange portions 1d of b, insert both the flange portions 1c and 1d into the groove portion of the ring band 5 having a substantially U-shaped cross section, and fix both ends of the ring band 5 with fixing tools such as bolts and nuts. The upper body 1a and the lower body 1b are fixed to each other and the main body 1 is formed in a spherical shape. Further, the upper portion 1a and the lower portion 1b of the main body 1 can be formed by a spatula diaphragm or the like.

The introduction pipe 2 is provided on the outer peripheral surface of the upper portion 1a of the main body 1, and the outlet pipe 3 is provided so as to extend from the top of the upper portion 1a of the main body 1 toward the inside of the main body 1 in the center direction. ing. The discharge pipe 4 is provided at the bottom of the lower portion 1b of the main body 1, and a valve 6 is provided below the discharge pipe 4.

Next, the operation and action of the spherical cyclone A will be described. The gas containing particles introduced into the main body 1 from the introduction pipe 2 by the blower or the like becomes a spiral spiral flow that descends while swirling along the inner wall of the main body 1, and centrifugal force acts on the particles during this time. The particles move toward the wall of the main body 1 and are separated from the air flow. The separated particles are discharged from the main body 1 through the discharge pipe 4 and the valve 6.
In the spiral spiral flow, the diameter of the spiral increases and the flow velocity decreases from the upper part to the lower central part.

Further, the diameter of the spiral becomes smaller as it goes downward from the central portion, the flow velocity rises, and an ascending air current is generated in the center and is led out from the lead-out pipe 3 to the outside of the main body 1.
Since the spiral spiral flow as described above is generated due to the shape of the main body 1, the pressure loss of the main body 1 is small, and a high flow velocity can be obtained in the upper and lower portions, so that particles that could not be separated in the upper portion are separated in the lower portion. And the ability to separate twice allows separation even with a large number of particles in the gas.

Next, the case where the spray nozzle of the spherical cyclone A is provided (generally called a cyclone scrubber) will be described. As shown in FIG. 3, the lower portion 1b of the main body 1
Spray nozzle 7 for spraying water or the like toward the center of the main body 1
Is provided, a liquid level sensor is provided in the lower portion 1b of the main body 1, and an automatic valve 6a operated by the liquid level sensor is provided below the discharge pipe 4.

The liquid level sensor 8 comprises an upper float switch 8a and a lower float switch 8b,
When the liquid level rises, the upper float switch 8a operates to open the automatic valve 6a, and when the liquid level falls, the lower float switch 8b operates to close the automatic valve 6a, which is sprayed into the main body 1. It is possible to prevent accumulated water or the like from being accumulated in the main body 1. Further, the water sprayed from the spray nozzle collides with the particles in the air stream, increasing the diameter of the particles and facilitating the separation from the gas.

Further, the case where the cyclone A is provided with a cooling / heating coil will be described. As shown in FIG. 4, a pipe 9 is wound around the outer periphery of the main body 1 in a coil shape. This pipe 9 is connected to a cooler and a heater (not shown), and the main body 1
When cooling the refrigerant, a refrigerant is flown into the pipe 9. By cooling the main body 1, the temperature in the main body 1 can be lowered and the gas in the main body 1 can be dehumidified, and the gas and particles can be separated well. Further, the cooling / heating coil may be wound around the outlet pipe 3 extending into the main body.

The present invention is not limited to the above embodiment,
For example, welding may be used to fix the upper portion 1a and the lower portion 1b of the main body 1.

[0019]

Since the present invention is configured as described above, it has the following effects. The cyclone body has a spherical shape, which makes it compact. In addition, it has a small pressure loss and can be operated with a blower with a small air flow.
