Integrated two-stage high-efficiency cyclone separator

Abstract

The invention discloses an integrated two-stage high-efficiency cyclone separator. The integrated two-stage high-efficiency cyclone separator comprises a casing (1), a gas inlet (11) formed in the middle of the casing, a gas outlet (12) formed in the upper portion of the casing, a sewage outlet (13) formed in the bottom of the casing, and a dust hopper (10) connected with the sewage outlet; a pre-separator (2), a first-stage cyclone separator (3), a gas rising pipe (4) and a second-stage cyclone separator (7) are arranged in the casing (1), the first-stage cyclone separator is arranged in thepre-separator, and a pre-separation cavity (21) is formed between the pre-separator and the first-stage cyclone separator; and the first-stage cyclone separator penetrates through the sewage outlet and communicates with the dust hopper, the first-stage cyclone separator communicates with the second-stage cyclone separator through the gas rising pipe, and the gas inlet runs through the casing and communicates with the pre-separator. Multi-stage separation is achieved in one separator, and the separator has high separation efficiency and low operation resistance and can operate stably for a longperiod; and impurities collected in each stage of separation are collected together and centralizedly discharged through the same sewage outlet.

Description

technical field [0001] The invention relates to a gas-solid / gas-liquid separation device, in particular to an integrated two-stage high-efficiency cyclone separator. Background technique [0002] As an important gas-solid separation or gas-liquid separation equipment, cyclone separator is widely used in chemical industry, petroleum , environmental protection, food and other industrial fields. Its working principle is that the dust-laden or liquid-laden airflow enters the cyclone separator through the air inlet, and the airflow rotating around its axis is formed in the cyclone separator. Under the action of centrifugal force, the dust or liquid droplets are thrown to the outer wall and discharged downward. The dust outlet is discharged, and the clean gas is discharged through the exhaust pipe in the center. [0003] The following working conditions are often encountered in industrial production: (1) The gas contains a relatively high concentration of impurities, and it is n...

AI Technical Summary

Problems solved by technology

But there are following deficiencies: (1) the separator divides the housing cavity into a plurality of end-to-end separation chambers with a partition, and the bottom of each stage of separation chamber is provided with a sewage outlet, that is, the separator has a plurality of sewage outlets , resulting in increased difficulty in the operation of the sewage discharge process and high labor intensity

At the same time, all sewage outlets need to install valves and instruments. The purchase and maintenance costs of valves and instruments will occupy a large proportion of equipment investment, especially in high-pressure working conditions, which will be expensive.

(2) The inlet of each stage of the separation chamber of the separator is provided with spiral blades or guide vane blades to rotate the intake air to achieve centrifugal separation, but such guide vanes are prone to clogging, especially when the gas phase contains viscous When there is a large amount of liquid (such as tar, etc.), the liquid mixed with dust can easily block the guide vane. Once the guide vane in the separator is blocked, it will be very difficult to clean, which is not good for the long-term stable operation of the equipment.
