Wet purification of air from dust in innovative irrigated nozzle of regular structure for ventilation of cabins of wheeled and tracked vehicles

Abstract

It was studied the mechanism of wet purification of air from dust in innovative irrigated nozzle of regular structure made from porous plastic plates and equipped with triangular protrusions in airducts that are located across the stream for artificial turbulence. Functional link between the effi- ciency of air purification from dust and reduction of temperature in adiabatic humidification was drawn out.

Energy savings through rationalization of exhaust ventilation emission treatment technology

“…Since water is supplied to the Venturi scrubber for irrigation under high pressure, which is about 0.25 MPa [8], the electric pump must consume at least 0.4 kW. Consequently, the power costs of the Venturi scrubber in total will be Nv = 3.7 kW.…”

“…To evaluate the parameters of the packing, we will take the following initial data: The calculation of the corresponding parameters of the packing is carried out using the expressions [8]:…”

“…In formulas ( 5) and ( 6), it is necessary to know the value of Еa, which can be determined by converting the expression obtained in [8] and reflecting the functional relationship between the efficiency Еa of reducing the air temperature in the nozzle and the efficiency 𝜼 𝒏 of air purification from dust:…”

Ensuring the environmental friendliness of internal combustion engines of agricultural machines in conditions of limited air exchange

“…The most attractive due to a certain simplicity is the supply of water to the internal combustion engine cylinders, as a result of which the air-fuel mixture is moistened. At the same time, water affects the chemical reaction of fuel combustion with the dissociation of water vapor into hydrogen and oxygen, as well as hydrogen and hydroxyl radical due to the high temperature during the combustion of hydrocarbon fuels [4]:…”
