Abstract

The utility model provides a nano -fluids fuel combustion characteristic testing arrangement with adjustable top cap, including a pipe body, body fire end sets up an arc top cap along body axial displacement along an orientation cutting formation opening that parallels to the axis on this opening, this top cap and open -ended are on a parallel with the terminal surface of body laminates mutually, moves when the top cap and exposes the opening, and the fluid burns in the opening cross -section department of exposing. Nano -fluids passes through the device can form comparatively stable flame, and burns solid residual collection sample easily.

Description

A kind of adjustable nano-fluid fuel combustion characteristics test device of top cover

Technical field

The utility model is related to a kind of fluent material combustion technology, the adjustable nano-fluid fuel combustion of particularly a kind of top cover Burn characteristic test device.

Background technology

Nano-fluid refers to that certain mode and ratio add nano level metal or metal oxide particle system in a liquid Uniform, stable, high heat conduction the novel heat exchange medium of standby one-tenth, has the advantages that low ignition point, high fuel value, the discharge of low stain thing, Receive the extensive concern of domestic and international researcher.However, the combustion mechanism of nano-fluid fuel is not perfect, therefore from basic angle The process that degree probes into nano-fluid fuel combustion has important theory significance and practical value.It is generally used for nano-fluid fuel The method of combustion characteristics research is single droplet burning test, and the method cannot test nano-fluid fuel continuous burning process, and Continuous burning is should be in nano-fluid fuel actual application, rather than simple individual particle droplet burning.

Easily there is oxidation reaction in the nano-particle being suspended in nano-fluid in nano-fluid fuel combustion process, collect And analyze the chemistry change that the solid residue of burning is occurred in nano-fluid fuel combustion process for analysis nano-particle Change and there is important effect, simultaneously facilitate nano-particle and the synergistic research of substrate fuel.Nano-fluid fuel is passed through general Logical quartz glass straight tube is simultaneously lighted in exit, then burning solid residue is gathered in pipe it is more difficult to collecting and sampling.Nano-fluid Fuel is passed through electric arc and jet-burner and lights in exit, then burning solid residue is scattered in end face, is difficult to concentrate, relatively Difficult collecting and sampling.

Content of the invention

The purpose of this utility model is to provide a kind of top cover adjustable nano-fluid fuel combustion characteristics test device, receives Meter Liu Ti can form relatively stable flame by this device, and the sampling of burning solid fraction collection is easily.

A kind of adjustable nano-fluid fuel combustion characteristics test device of top cover, including body, described body fire end edge Direction cutting parallel to axis forms an opening, and on this opening, setting one is along the arc top cover of body axial movement, this top cover Fit parallel to the end face of body with opening, when opening is exposed in top cover movement, fluid fires at the opening section being exposed Burn.

Using said apparatus, top cover parallel to body end face along the axially arranged key of body, opening parallel is in the end of body Face is along the axially arranged straight-line groove mating with key of body.

The utility model compared with prior art, has advantages below：(1) movement by cell body for the utility model, its The area respective change of port, is adapted to the fluid of the different in flow rate effect to reach stable burning, by the physics of flame Measurement, the performance of estimation nano-fluid fuel；(2) after burned, burning solid residue is gathered in half opening cambered surface, to this combustion Burn solid residue and be collected sampling easily.

With reference to Figure of description, the utility model is described further.

Brief description

Fig. 1 is structural representation of the present utility model.

Fig. 2 is body combination schematic diagram at top cover of the present utility model and opening.

Fig. 3 is the utility model generalized section.

Fig. 4 is the utility model fluid combustion schematic diagram, the time interval of two often adjacent width figures wherein in (a) to (h) For 2ms.

Specific embodiment

In conjunction with Fig. 1, a kind of adjustable nano-fluid fuel combustion characteristics test device of top cover, including body 1, described body 1 fire end forms an opening along the direction cutting parallel to axis, and it is in ladder dress that this opening makes body.One is arranged on this opening Along the arc top cover 2 of body 1 axial movement, this arc top cover section center of circle is located on body 1 axis.This top cover 2 lower surface and The end face parallel to body 1 axis of opening fits, and when opening is exposed in top cover 2 movement, fluid is in the opening section being exposed Place's burning.

Because the wall at opening can be played a supporting role to fluid during burning, therefore flame can stably burn. Through experiment, described opening is formed along axis cutting by body 1 fire end and can obtain flame the most stable.

In conjunction with Fig. 2, along the axially arranged raised key of body (1), opening parallel is in the end face of body 1 for top cover (2) lower surface Along the axially arranged straight-line groove mating with key of body 1.In conjunction with Fig. 3, body (1) outer wall is provided with rectilinear orbit groove vertically, top Lid inwall is provided with the feather key mating with rail groove.Sealing ring 4 is set between top cover 2 and body 1.

In conjunction with Fig. 4, it is 1.0% 100nm aluminum particulate with ethanol for when flow is for 0.5ml/min, adding concentration For substrate nano-fluid when, in this utility model device burn, its flameholding can be observed, wherein in (a) to (f) Often the time interval of two adjacent width figures is 2ms.
