The spiral-flow filter connector comprises a spiral-flow separation part and a confluence separation part, wherein the spiral-flow separation part is used for rotating a fluid mainly by virtue of a main body with a spiral spiral-flow groove, so that foreign matter in different masses can be separated, then the fluid is secondarily separated and filtered by a separation assembly with a diverging opening in the confluence separation part, twice separation of the fluid can be realized through a simple structure, and the spiral-flow filter connector is convenient to install and low in manufacturing cost.

The invention provides a high-grease-separation-degree extractor hood and a built-in spiral separation device thereof. The built-in spiral separation device comprises an inner shell, a cylinder and spiral plates; the inner shell is connected with the interior of an outer shell of an overall machine of the extractor hood; the outer edge of the upper end of the inner shell and the interior of the outer shell of the overall machine are in sealed connection, a ventilating duct for smoke discharging is formed in the middle portion of the inner shell, and a flue is formed by the outer side of the inner shell and the outer shell of the overall machine; the top of the cylinder is connected with the inner shell, at least one ventilating opening is formed in the periphery of the top of the cylinder, and the bottom of the cylinder is closed and is provided with an oil collecting pipe; the cylinder is vertically fixed into the flue and divides the flue into an outer side flue close to the outer shell of the overall machine and an inner side flue close to the inner shell; the outer side flue is communicated with a smoke inlet of the extractor hood, and the inner side flue is communicated with the ventilating duct; and the spiral plates are fixedly installed on the inner side and the outer side of the cylinder correspondingly. The smoke inlet of the extractor hood is communicated with a smoke outlet of the extractor hood through the outer side flue, the ventilating openings, the inner side flue and the ventilating duct in sequence.

A related secondary reverse-flow type filtering joint comprises a swirling separation part, a conflux separation part and a reverse flow part; the swirling separation part rotates a fluid mainly through a main body provided with a spiral swirling tank, so that impurities with different mass are separated; the fluid is subjected to secondary separation filtration in a separation assembly with a gradually divergent opening in the conflux separation part; and then the reverse flow part enables impurities deposited in the separation assembly to flow back to the swirling separation part through a liquid flow. Therefore, secondary separation and secondary reverse flow of the fluid are realized through the simple structure, obstruction of the conflux separation part caused by excessive impurities is effectively prevented, and the secondary reverse-flow type filtering joint is convenient to mount and low in cost.

The invention discloses a secondary chlorine gas injection device for a fine-particle titanium raw material boiling chlorination furnace. The secondary chlorine gas injection device comprises a boiling chlorination reactor main section, a secondary chlorine gas injection section, a furnace top, a secondary chlorine gas introducing hole, an inverted U-shaped tube shell and a cyclone separator. The cyclone separator is used for separating solid powder and gaseous TiCl4; an ascending tube is arranged in the middle of the cyclone separator, and the lower part of the cyclone separator is communicated with a circulating return leg. The secondary chlorine gas injection section, an outlet of the furnace top, the cyclone separator and the circulating return leg are communicated in sequence, and an inverted U-shaped pipeline is formed at the furnace top. The inverted U-shaped tube shell is arranged outside the inverted U-shaped pipeline and forms a sealed secondary chlorine gas injection channel together with the inverted U-shaped pipeline. The mutual effect of rotational shear of gas and solids at the upper part of the boiling chlorination furnace and the centrifugal separation effect are enhanced, so that the escaped fine particles which not completely react are reduced; and meanwhile, the chlorination reaction efficiency and the yield of TiCl4 are increased, and the temperature of the TiCl4 gas at the top of the boiling chlorination furnace is balanced.

The invention discloses an inwardly double inlet-type multistage separation type dust collector. The dust collector comprises a housing, a dust cup and a dust collection motor. The dust cup comprisesa cup body, a cup cover and a bottom cover. A first air inlet and a first air outlet are arranged in the dust cup. The inside of the cup body is equipped with a filter cylinder and a second-stage separator. The second-stage separator separates the cup cover from the cup body. The second-stage separator comprises multiple cyclone separation cones. Lower end openings of the cyclone separation conesare less than the opening diameter of the upper end. The side wall of each cyclone separation cone is equipped with two tangential air supply pipes located in the interior of the cup cover. The lowerend of each cyclone separation cone communicates with the interior of the filter cylinder. The upper end of each cyclone separation cone communicates with the interior of the cup cover. The housing isequipped with a primary suction opening and a main discharge opening. The inwardly double inlet-type multistage separation type dust collector has the following beneficial effects: air flows can be dispersed in order to increase relative flow speed of each dispersion air flow; additionally, by increasing relative air inlet amount, centrifugal separation effect is enhanced; the final separation effect of dust is improved; and the dust collection capability is strong.
