Integrated measuring device for flow density distribution of large-size spraying field

Abstract

The invention discloses an integrated measuring device for flow density distribution of a large-size spraying field. The integrated measuring device is composed of a water collector, an L-shaped fixing rib, an integrated cover plate and a rack, wherein the water collector is formed by digging measuring holes in the same size and regular arrangement on rectangular plate made of a transparent material; the long arm of the L-shaped fixing rib is adhered and connected with the water collector; the L-shaped fixing rib is fixed on the rack through a positioning screw hole on a short arm; the measuring holes on the water collector are vertically upward formed at measuring positions in the spraying field; the cover plate is connected with the top of the fixing rib through a rotating shaft; at the beginning or ending of measurement, the cover plate is opened or closed around the rotating shaft; a transparent scale bar is attached to the side wall of the water collector, wherein the starting scale is aligned with the bottom of the measuring holes; plate parts outside the orifices of the measuring holes are cut according to a certain radian, in order to avoid measurement error caused by the liquid drop outside the orifices which splashes into the measuring holes after colliding with the measuring device; and the height of the rack is adjustable, so that the flow density distribution condition on different spraying cross sections is measured.

Description

technical field [0001] The invention relates to the fields of spray head design and atomization performance evaluation, and relates to the measurement of the flow density distribution of a large spray field, especially an integrated measuring device for the flow density distribution of a large spray field. Background technique [0002] There are a large number of atomizing spray and cooling systems in nuclear reactor operation and safety emergency systems. Among them, the voltage stabilizer, which plays an important role in the operation of the system, uses a low-pressure drop and large-flow spray head, which will produce a large spray field when the pressure is reduced and sprayed. During the design stage of the spray head and the screening process of the spray head according to the requirements of use, the flow density distribution in the atomized flow field must be understood in detail through experiments. On the basis of measuring the flow characteristics and the atomiz...
