Technical Field

The invention relates to the technical field of gas-liquid separation devices, in particular to a vertical cyclone separator.

Background

The cyclone separator is suitable for cleaning non-sticky, non-fibrous dry dust larger than 1-3 microns. The cyclone dust collector is a purification device with simple structure, convenient operation, high temperature resistance and higher equipment cost and resistance, and the cyclone dust collector is most widely applied to the purification device.

The vertical cyclone separator adopts a vertical cylinder structure, and the interior of the vertical cyclone separator is axially divided into a liquid collecting area, a cyclone separation area, a purification chamber area and the like. The smoke inlet channel introduces smoke into the cyclone separation area, and the smoke is centrifugally separated in the rotating process. The existing vertical cyclone separator mainly depends on a spiral smoke inlet channel to rotate and centrifuge smoke, centrifugal force promotes liquid and solid in the smoke to be separated, and the cyclone separation effect of the smoke is to be improved. The smoke exhaust channel extending into the separation cavity is generally short, and if the smoke exhaust channel is long, smoke upwards moves in the separation cavity, so that the exhaust resistance is large, and the exhaust effect is poor.

Disclosure of Invention

The invention aims to solve the problems and provide a vertical cyclone separator.

In order to solve the problems, the technical scheme adopted by the invention is as follows:

vertical cyclone, including separation cavity, ash bucket, income cigarette passageway, exhaust passage, the separation cavity outside is equipped with spiral helicine income cigarette passageway, and exhaust passage sets up inside the separation cavity, and the exhaust port of exhaust passage top sets up in the separation cavity outside, and the separation cavity bottom is equipped with the ash bucket, its characterized in that is equipped with the heliciform blade on the inside exhaust passage of separation cavity, and the interior pipe hole in the exhaust passage bottom is venturi.

Preferably, a vortex cover is arranged at the connecting port of the ash bucket and the separation cavity.

Preferably, the smoke outlet is helical.

Compared with the prior art, the invention has the advantages that:

the smoke enters the separation cavity from the smoke inlet channel, and continues to move downwards in a spiral shape under the guidance of the spiral blades, the spiral blades lengthen the rotation path of the smoke, and the smoke is separated into liquid or solid particles by centrifugation, so that the separation effect is improved; in the rotating operation process, the smoke collides with the spiral blades, and liquid and solid particles in the smoke are further separated.

The inner pipe hole at the bottom of the smoke exhaust channel is a Venturi tube, when smoke is guided to the bottom of the smoke exhaust channel by the spiral blades, the smoke is sucked and introduced into the smoke exhaust channel by the Venturi tube under the siphon negative pressure generated by the Venturi tube, and in the rising process of the smoke exhaust channel, the smoke is further promoted to separate liquid due to the pressure reduction in the negative pressure area of the Venturi tube.
