COLLECTOR FOR INJECTION OR DRAINAGE OF GAS FROM APPARATUS FOR AIR- BASED COOLING OF GAS Russian patent published in 2005 - IPC

FIELD: power engineering, in particular, heat exchange devices, primarily, air-based gas cooling apparatuses.

SUBSTANCE: device is made in form of reservoir working under pressure, including cylindrical body with end portions of two-side curvature, central branch pipe for connection to gas main and branch pipes for connecting to chambers for inlet or outlet of gas of heat-exchange sections of air gas cooling apparatus, while cylindrical body is made of technological sections, central one of which is made primarily in form of unified technological element with central branch pipe, and branch pipes for connection to chambers for inlet and outlet of gas of heat exchange sections of air gas cooling apparatus are mainly symmetrically positioned on both sides from central technological section and number of these branch pipes on each side ranges from 2 to 8, while the area of cross-section in light of central branch pipe is 0,7-1,0 of area of cross-section in light of cylindrical portion of body of collector fro injection or drainage of gas, and total area of cross section in light of branch pipes for connection to chamber for inlet or outlet of gas of each heat-exchange section of air-based gas cooling apparatus is 0,37-0,62 of area of cross-section in light of cylindrical portion of body of collector for injection or drainage of gas.

EFFECT: decreased metal cost of gas injection or drainage collector and higher manufacturability of its construction, and also decreased hydraulic losses in collector for injection or drainage of gas.
