The invention relates to a method for waste-gas purification in degasification plants using a device (16) for generating a negative pressure, in particular by means of steam jet ejector pumps or mechanical vacuum pumps. It is provided according to the invention that the waste gas passing from a vacuum chamber (15) is conducted into a cyclone separator (12), and in that the method steps of coarse separation of particles from the waste gas and fine-dust separation of particles from the waste gas and gas cooling in the cyclone separator (12) are carried out in succession in such a way that the waste gas, after coarse purification has taken place, is conducted directly via a fine dust filter (13) installed in the cyclone separator (12) and subsequently through a gas cooler (14), which follows the fine dust filter (13), into a suction line (2) which is connected to the device (16) for generating a negative pressure, and to the device (16).

Disclosed in a filter for filtering a working fluid comprising a canister having an inlet and an outlet; a first partially perforated generally conical member positioned in said canister; a second generally conical member positioned inside said first partially perforated generally conical member, whereby the working fluid upon entering the inlet is caused to spin inside the canister, to pass through the perforated portion of the first generally conical member, to enter an inlet to the second generally conical member, to spin within the second conical member and to pass through the outlet.

The invention relates to a preseparator means for a dust collector. The preseparator means comprises: at least two dust separation units (2A, 2B), each adapted to receive a gas flow carrying dust particles at an inlet (3A, 3B), separating and collecting at least a part of the dust particles from the gas, and emitting the gas thus treated at an outlet (4A, 4B); switching means (8) adapted to switch the operation between said separation units (2A, 2B), so that each separation unit is shut off from the gas flow intermittently, in order to allow removal of collected dust particles from the shut off separation unit, while the other separation unit is in operation. The invention enables continuous operation of the preseparator means.

Trickle valve (9) positioned at the lower end of a vertical dipleg (8) of a gas-solids separator (5) comprising a pair of co-operable clamshell doors arranged in such a manner that mutual opposite swinging movement between a closed position wherein the doors adjoin along a midline, and an open position wherein the doors swing outwardly around a horizontal axis of rotation, is possible, and wherein either clamshell door is provided with means to press the doors together towards a closed position and at least one clamshell door is provided with an opening.
