To calculation of pneumoshutters

The articles describes the original constructive arrangements of pneu-moshutters - the devices preventing emission of aggressive gases from reactors in to environment. The physical and mathematical model of vortex type pneumoshutter is developed and its characteristics expressing dependence of the specific mass flow rate of air from the relative value of pressure in the reactor are calculated. The method of calculation of the vortex pneumoshutter, illustrated with a numerical example is offered. The results of calculation are compared with calculation data of a pneumoshutter of ejecting type.
