Abstract
The present invention relates to a cyclone, mainly for separating liquid from gas/vapor which is formed on pressure reduction of spent cooling liquor in connection with pulp production. The cyclone includes a casing, an inlet arrangement, a lower outlet line for liquid and an upper outlet line for vapor and gas. The inlet arrangement is connected to a supply line with a valve and the inlet arrangement consists of an exchangeable insertion pipe, the length of which exceeds one meter, preferably two meters and is most preferably between 2.5 and 3.5 meters long.
Claims20
In a first cyclone for separating a gas from a liquid stream, said cyclone including an upper portion, said upper portion having an inlet opening for said liquid stream, the improvement comprising:
- at least one interchangeable insertion pipe, said at least one interchangeable insertion pipe having a preselected and constant cross-sectional area, having a diameter which is less than the diameter of said inlet opening, and having a length of greater than about 1 meter, said at least one interchangeable insertion pipe being adapted for insertion into said inlet opening and adapted for connection to a supply line for said liquid, said supply line including pressure drop creating means therein, wherein said at least one interchangeable insertion pipe can be interchangeably inserted into said inlet opening.
