Description

Cyclone separator with gas-liquid separation device

Technical Field

The utility model relates to a cyclone especially relates to a cyclone with gas-liquid isolating device.

Background

In chemical production, separation of solvent and solute is often required, generally, a gas-liquid mixture is formed after a solution is gasified, wherein most of the solvent forms gas, the solute forms fine particles or forms micro liquid drops after being dissolved in the rest of the liquid solvent, a cyclone separator is adopted to carry out gas-liquid separation on the gas-liquid mixture, and the liquid drops which are not gasified form a liquid film in the cyclone separator and are then collected. However, the formed liquid film is easily broken by the influence of the movement of the gas in the cyclone separator, and the broken liquid is discharged from an overflow pipe of the cyclone separator along with the gas, so that a part of solute is mixed in the gas discharged by the overflow pipe, and the separation effect is deteriorated. In addition, in order to collect more solvent, a heater is arranged outside the lower cone part of the cyclone separator to evaporate the solvent, and the heated liquid film is more easily affected by gas so that the solute mixing of the overflow pipe is more serious.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cyclone with gas-liquid isolating device solves the liquid film that contains the solute and receives the gas disturbance problem, improves the separation efficiency of solution.

The technical scheme of the utility model is like this: a cyclone separator with a gas-liquid isolating device comprises a gas inlet pipe, a cyclone cavity, an overflow pipe and a truncated cone cavity with a large upper part and a small lower part, wherein a plurality of annular blades which are stacked are arranged in the cavity of the truncated cone cavity with the large upper part and the small lower part, the annular blades are truncated cone rings with the large upper part and the small lower part, and gaps are formed between the annular blades and the inner wall of the cavity of the truncated cone cavity with the large upper part and the small lower part.

Further, the annular blade is coaxially arranged with the truncated conical cavity with the large upper part and the small lower part.

Further, the clearance between the annular blade and the inner wall of the cavity of the truncated cone cavity with the large upper part and the small lower part is 10-15 mm.

Further, the width of the annular blade is 20-28 mm.

Further, the vertical height of the covering between the adjacent annular blades is 3-5 mm.

Further, the included angle between the conical generatrix of the annular blade and the horizontal direction is 50-60 degrees.

Further, the diameter of the annular blade is not smaller than the diameter of the bottom end opening of the truncated conical cavity with the large upper part and the small lower part.

Further, the outer wall of the cavity of the truncated cone cavity with the large upper part and the small lower part is provided with a heater.

The technical scheme provided by the utility model has the advantages that on one hand, the annular blade is utilized to isolate the gas in the cyclone separator in the middle from the liquid drops on the inner wall of the cavity of the truncated cone cavity, thereby reducing the disturbance of gas motion to the formation of the liquid film and preventing the liquid film from being broken and then being discharged from the overflow pipe along with the gas; on the other hand, the liquid drops brought up after heated evaporation can be enabled to reconstruct a liquid film on the annular blade, and the discharge of the solute from the overflow pipe is further reduced. The reasonable size setting can not only block the liquid film with cracked wall surface, but also prevent the resistance of the gas flowing from being too large, and reduce the pressure drop in the cyclone separator.

FIG. 2 is a partial schematic view of the annular vane and the cavity of the frusto-conical chamber.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Please refer to fig. 1 and 2, in the cyclone separator with a gas-liquid isolating device according to the present embodiment, the cyclone separator includes an air inlet pipe 1, a cyclone chamber 2, an overflow pipe 3, and a truncated cone chamber 4 with a large top and a small bottom, wherein a heater 5 is disposed on an outer wall of the truncated cone chamber 4 with the large top and the small bottom, and the structure is the same as the prior art, and the operation principle is not repeated

This cyclone during operation, gasification's material gets into cyclone, the gas portion is discharged from overflow pipe 3, the inner wall of the cavity of the truncated cone chamber 4 of liquid droplet part big-end-up forms the liquid film and heats, gas after the heating gasification and the gas by cyclone centrifugation direct separation are discharged from overflow pipe 3, the cracked liquid film of wall breaks away from the wall simultaneously and is separated by annular blade 6, annular blade 6 can block the influence of gas motion to the liquid film simultaneously, the motion time of liquid film big-end-up's truncated cone chamber 4 has been prolonged, thereby improve the rate of gasification and separate solvent and solute better. The gap d between the annular blade 6 and the inner wall of the cavity of the truncated conical cavity 4 with the large upper part and the small lower part is 10-15 mm, so that the annular blade 6 is prevented from being inserted into a liquid film due to the fact that the annular blade 6 is too close to the wall surface; at the same time, the annular blade 6 is prevented from being too far away from the wall surface, so that the pressure drop in the cyclone separator is increased. The vertical height H of the cover between the annular blades 6 is 3-5 mm, namely, a liquid film with a broken wall surface is blocked, and the resistance of gas flowing is not too large.
