Abstract
The utility model relates to a non-point source pollutant releasing device used for a wind tunnel experiment. The non-point source pollutant releasing device is mainly composed of a cuboid stainless steel shell, a non-point source pollutant inlet, six inlet circular holes distributed uniformly, two metal nets arranged perpendicular to the shell, and a non-point source pollutant outlet. The requirement on the uniformity of non-point source pollutants is relatively high so that the six circular holes are arranged at the non-point source pollutant inlet to realize the objective of pipeline transportation, a fully mixing section is reserved in a pipeline for the pollutants, and the pollutants are already primarily mixed when the pollutants reach the inlet. The air pollutants pass through the two vertical metal nets in the shell to be fully and uniformly mixed so that the pollutants released by the outlet have better uniformity.
Description
Technical field
This utility model relates generally to is face source dispensing apparatus in wind tunnel experiment, says more accurately the device that the non point source of pollution continuous uniform is provided in the wind tunnel experiment.
Background technology
Along with society is showing improvement or progress day by day and develops, the people's living standard and quality of life are also become better and better, and the recoverable amount of motor vehicle also increases day by day, and people are when sighing with feeling the developing rapidly of one day sample of society, and the environmental pollution that motor vehicle brings is also serious all the more.Contain solid suspended particles, carbon monoxide, oxides of nitrogen, hydrocarbon etc. in the motor-vehicle tail-gas, live in for a long time that the health for the people has very big negative effect under the serious environment of tail gas pollution of motor-driven vehicle.The research of relevant motor-vehicle tail-gas mainly contains three kinds of methods, is respectively Computer Numerical Simulation, wind tunnel experiment, field measurement.Can form stable wind environment in the wind tunnel experiment, be fit to carry out scientific research, the parent who therefore is subject to vast researcher looks at.What the face source dispensing apparatus in the wind tunnel experiment was simulated is the wind tunnel experiment that motor-vehicle tail-gas is discharged from the tunnel face in the tunnel, and the tunnel face can be regarded non point source of pollution as.
Go back nobody before the non point source of pollution dispensing apparatus in the wind tunnel experiment and relate to, wind tunnel experiment point pollution source dispensing apparatus and line source dispensing apparatus are arranged, the exhaust emissions that is respectively chimney and motor vehicle of simulation before.The dispensing apparatus in face source from continuous, even, stable the sending of rectangle exit face, provides support aspect the experiment in tunnel face discharging CFD simulation for automobile exhaust pollution thing in the simulation tunnel pollution source in the wind tunnel experiment.
The utility model content
The utility model provides the non point source of pollution dispensing apparatus for wind tunnel experiment, because the at present domestic non point source of pollution dispensing apparatus that there is no for wind tunnel experiment, so this face source dispensing apparatus has been filled up the blank that the wind tunnel experiment pollution source of simulation tunnel mouth pollutant are provided this technical field.
The utility model relates to a kind of face source dispensing apparatus for wind tunnel experiment, it is characterized in that having: the rectangular parallelepiped housing; Be arranged on the pollution source import of an end of rectangular parallelepiped housing; Pollution source inflow point is provided with 6 and is used for making pollution source enter the circular port of rectangular parallelepiped housing; 2 wire nettings that are vertically installed in the rectangular parallelepiped enclosure interior; And face source outlet.
Pollution source enter in the housing by 6 rubber catheters on 6 circular holes that are connected to pollution source inflow point, and wire netting is parallel to imports and exports setting, and grid order number is identical, and are mutually vertical between the different aspects mesh lines.
Effect of the present utility model:
The utility model utilizes the wire netting combination that flue gas is mixed in enclosure interior, guarantees the flue gas homogeneity, makes simultaneously the face source flow stable.
After the flue gas access to plant, there are enough paths to finish the homogenising of gas itself.The homogeneity of the homogeneity of this technique guarantee gas own and the outlet of face source, and economical with materials and resource, cost of manufacture is low, occupies volume little, and pipe resistance is little, and shunt paths is simple, and fluid well-distributing is better.
The planar flue gas that adopts the utility model to provide out, each exhaust gas volumn, air pressure and velocity of flue gas of providing point is all almost identical, can control the homogeneity that produces flue gas, and the homogeneity of providing, satisfied the granting requirement of simulation uniform surface pollution source in the wind tunnel experiment, so that test findings is truer, more accurate.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the utility model device.The present invention is the face source dispensing apparatus for wind tunnel experiment, main member includes: stainless steel metal rectangular parallelepiped housing, and pollution source import (1), inflow point is two-layer 6 circular ports (2) of arranging evenly, the wire netting of 2 parallel placements (3), pollution source outlets (4).Face pressure vessel body, profile is the rectangular parallelepiped of the high 22cm of being respectively of length and width, 6cm, 3cm, adopts evenly the distribute circular port of 6 diameter 1cm of stainless steel, inflow point, divide two-layer, every layer of 3 circular hole are evenly arranged, and 6 rubber wireways connect 6 circular holes of inflow point, reach the air guide purpose, in the housing, apart from import 6cm and 8cm place, 2 stainless steel wire meshes are set respectively, size is 6cm * 3cm(to be grown * wide).Two wire netting arranged parallel, the grid of two adjacent wire nettings intersects mutually, and the wire-mesh screen hole dimension is 10 orders, the outlet size length and width are 6cm * 3cm, the sizing grid of the described wire netting of every one deck is identical, and evenly distributes, and is mutually vertical between the mesh lines of different aspects.
Experiment is connected on pipe first on the flue gas generation mixing arrangement of good airproof performance, flue gas and air are mixed in this device, air is inputted mixing arrangement by pneumatic pump, air velocity can be adjusted as required, flue gas mixes the formation pollution source with air, flue gas generation mixing arrangement links to each other by 6 rubber catheters with face source dispensing apparatus, rubber catheter just is fixed on the circular hole (2) of face source dispensing apparatus, flue gas is by conduit entering surface source dispensing apparatus, enter in the housing, and be 10 stainless steel wire mesh by 2 order numbers, arrive at last outlet, the outlet of this device is fixed in the experimental wind tunnel, forms the face source of steady and continuous.
When the utility model uses, the at first selected incendiary material of making good uniformity produces flue gas, then mix with the air-flow of certain speed, can produce the face source through face source flue gas dispensing apparatus, the flue gas that burning produces, through behind the plenum chamber, become uniform and stable, then combination mixes gas in vertical plane through wire netting, guarantee gas uniform, guarantee that the inhomogeneity while of gas itself can guarantee again gas homogeneity on the whole length in housing, more economical with materials and resource, cost of manufacture is low, shared volume is little, pipe resistance is little, and shunt paths is simple, and fluid well-distributing is better.
