Abstract
The invention relates to a fluid mixing device with low pressure loss. The fluid mixing device comprises a spiral flow disturbing body (1) and an outer pipe (2),wherein the spiral flow disturbing body(1) is fixed inside the outer pipe (2); the spiral flow disturbing body is characterized in that the spiral flow disturbing body (1) and the inner wall of the outer pipe (2) form a flow passage (3) from which the fluid rotationally passes through; the spiral flow disturbing body(1) is provided with penetrating flow disturbing holes (4); when the fluid enters the outer pipe, the fluid is mixed in the process of moving forward in the flow passage under the action of the spiral flow disturbing body (1). According to the invention, the fluid mixing device not only can be applied to uniform mixing of two different types of fluids, but also the fluid mixing device can provide fluid fields conducive to chemical reactions, such as the SCR system before the chemical reactions start; sufficient and quick generation of the reactions are ensured and the working efficiency of the overall system is improved. The fluid mixing device has relatively small flow resistance and can lower the pressure resistance during the mixing process of the fluid.
Description
Technical field
The present invention relates to a kind of test pipe device, be specifically related to a kind of for burning, the fluid mixer of the chemical reaction such as hydrolysis.
Background technology
Special disposal is not done in flow field before general industry chemical reaction, for example the incoming flow gas of Diesel engine selective catalysis reaction SCR system is directly to be provided by the exhaust pipe of engine, so just caused at urea during to exhaust blast, mixing uniformity and reaction rate are affected.One is evenly reasonably reacted initial flow-field for chemical reaction, is necessary very much.
Application number a kind of efficient gas-liquid mixer device that has been 201120187482.8 disclosure of the invention, it comprises that a lower house, a upper shell, two sealing rings, mix hydroecium, two nuts, two sealing gaskets.This upper-lower casing and seal form a gas-liquid mixed chamber, and at side opening one water inlet of mixing chamber, outside connects a little water pump; Open an air inlet in hybrid-type bottom, open gas liquid mixture outlet at mixing chamber top; The inside of lower house is cone-type spiral step surface, the salient point of regular distribution on step surface.The external little water pump of this blender water inlet, solution is by the supply of water pump, enter by water inlet, the gas entering with bottom air inlet, jointly reach in mixing chamber, the type conical bench face that relies on again lower house inside, spiral rotating voluntarily mixes in mixing chamber, and then enters and mix hydroecium and reach the object that improves the gas amount of carrying in the solubility of gas in solution and unit volume solution.
Application number a kind of mixer aluminium oxide ceramics composite screw liner plate that has been 201220194301.9 disclosure of the invention, comprise that trommel mixer obtains inner barrel aluminium oxide ceramic composite lining board is set, the surface of this aluminium oxide ceramic composite lining board is with protruding conveyor screw, wherein being arranged on the aluminium oxide ceramics mixing liner plate of trommel mixer feeding end is to have forward projection conveyor screw, with its link on discharge end aluminium oxide ceramic composite lining board with the retrograde protruding conveyor screw contrary with material running orbit.Therefore, can improve pelletizing rate and realize stock grading by protruding conveyor screw, having extended effective mixed pelletizing time, increasing the material distance of effectively rolling, thoroughly having solved mixer root buildup, be stained with material problem, greatly having improved pelletizing effect and service life.
The fluid mixer of prior art has all adopted leptospira structure, but there is no taking into account system resistance, has the excessive technical problem of the pressure loss.
Summary of the invention
The present invention is directed to the excessive technical problem of the fluid mixer pressure loss of the prior art, technical problem to be solved, a kind of fluid mixer of low pressure loss is provided, and this device can provide one evenly reasonably to react initial flow-field for chemical reactions such as burning, hydrolysis.
Technical scheme of the present invention: a kind of fluid mixer of low pressure loss, comprise spiral turbulent 1 and outer tube 2, described spiral turbulent 1 is fixed on outer tube 2 inside, it is characterized in that: described spiral turbulent 1 forms with outer tube 2 inwalls the runner 3 that fluid rotaries pass through; On described spiral turbulent 1 with the flow-disturbing hole 4 of running through.
This device of the present invention can be applied to two kinds of different fluid well-distributings to be mixed, can also be for providing the flow field that is beneficial to reaction before the chemical reactions such as SCR system, ensure that reaction can occur fully fast, improve the operating efficiency of whole system, adopt the design in flow-disturbing hole can further improve the uniformity of mixing, and further reduce the flow resistance of mixing arrangement, reduce the pressure loss of fluid.
Brief description of the drawings
Fig. 1 is vertical profile structural representation of the present invention;
Fig. 2 is top view of the present invention.
Detailed description of the invention
The first embodiment: a kind of fluid mixer of low pressure loss, comprise spiral turbulent 1 and outer tube 2, described spiral turbulent 1 is fixed on outer tube 2 inside, it is characterized in that: described spiral turbulent 1 forms with outer tube 2 inwalls the runner 3 that fluid rotaries pass through; On described spiral turbulent 1 with the flow-disturbing hole 4 of running through.After fluid enters outer tube, under the effect of spiral turbulent, along advancing process with the runner of outer tube 2 inwall compositions in, evenly mixes spiral turbulent, a part of fluid enters runner through spiral turbulent from vertical direction by flow-disturbing hole 4 simultaneously, disturb the motion of original fluid in runner, and in this process, make two kinds of fluids further evenly mix, and can play and further reduce circulating resistance, the effect of the pressure loss of the fluid passing through reduced.
Preferably spiral turbulent and outer tube adopt cast iron, stainless steel or ceramic material.
Preferably outer tube 2 two ends connected modes are flange, clip or cannula structures.
Flow-disturbing hole 4 symmetric arrays that preferably run through on spiral turbulent 1, fluid can be cancelled each other to the reaction force of spiral turbulent 1 during by flow-disturbing hole 4, is conducive to further reduce circulating resistance, reduces the pressure loss of fluid.
The second embodiment: a kind of fluid mixer of low pressure loss, comprise spiral turbulent 1 and outer tube 2 and motor, described spiral turbulent 1 is movably arranged on outer tube 2 inside, it is characterized in that: described spiral turbulent 1 forms with outer tube 2 inwalls the runner 3 that fluid rotaries pass through; Described spiral turbulent 1 is connected with motor, under the drive of motor, rotates.
In the present embodiment, fluid enters after mixing arrangement, and spiral turbulent rotates under the drive of motor, force fluid in motion process, to complete mixing, the rotation of spiral turbulent, can also convection cell acting except can lifting fluid mixing uniformity, further reduces the pressure loss of fluid.
Preferably on spiral turbulent 1 with the flow-disturbing hole 4 of running through.After fluid enters outer tube, under the effect of spiral turbulent, along advancing process with the runner of outer tube 2 inwall compositions in, evenly mixes spiral turbulent, a part of fluid enters runner through spiral turbulent from vertical direction by flow-disturbing hole 4 simultaneously, disturb the motion of original fluid in runner, and in this process, make two kinds of fluids further evenly mix, and can play and further reduce circulating resistance, the effect of the pressure loss of the fluid passing through reduced.
