Abstract

The dust-absorber effective work is characterized by the relation between an exit and entrance dust concentrations and its dynamics. Dust concentration level changes are direct indicator of its technical status. The IVA-L type dust concentration measurement laser instrument allows to provide automatic continuous diagnosting of a technical status of a dust-absorber. Integrated laser radiation Mie scattering on particles moving in an air flow method lies in a basic of this instrument work. It is created as uniform optical-electronics module which is usually established directly on a wall entrance an exit of gas pipes of a dust-absorber. IVA-L instrument output signal is equal to the dust mass concentration level. The IVA-L testing and certificate verification were made on the special laboratory apparatus carried out as dust air flow closed ellipsoid form pipe of 4 X 6 m. The IVA-L instrument application as dust concentration level recorder provides the whole operative information about a technical status of the dust-absorber and therefore can prevent additional of dust pollution to atmosphere at this industrial region.
