Abstract

The invention discloses a linear low-pressure water mist contraction-expansion nozzle with a gas-liquid mixing chamber. The problems that a traditional atomizing nozzle is short in spraying distance, the cost of a water storage container is high, and water is not prone to being supplemented are solved. The linear low-pressure water mist contraction-expansion nozzle totally comprises a laval spraying pipe section, the mixing chamber, a water delivery pipe connector and a nozzle outlet end; the speed of atomizing gas is increased to the supersonic speed by the laval spraying pipe section through a contraction-expansion superspeed spraying pipe; the mixing chamber is a cylindrical blind hole and connected with a water delivery pipe; one side of the water delivery pipe connector is connected with the mixing chamber through a thread, and the other side of the water delivery pipe connector is connected with the water delivery pipe; and a nozzle outlet is round, and thus water mist can be sprayed out easily. The linear low-pressure water mist contraction-expansion nozzle has the advantages that water is stored under normal pressure, safety and convenience are achieved, cost is low, the atomizing effect is good, the spraying distance is long, and the linear low-pressure water mist contraction-expansion nozzle has high promotional value.

Description

Self-priming two-phase flow atomizer
Technical field
The present invention relates to a kind of straight line low pressure water mists reducing and expansion type nozzle with gas-liquid mixed chamber, makes to be atomized and make the more remote self-priming two-phase flow atomizer of droplet injection at ambient pressure with current especially with low-pressure air current.
Background technology
Two-phase flow atomizer, is that fluid column or liquid film are dispelled the nozzle that is broken into drop by means of the kinetic energy of flowing gas, and the distance and current of drop jet length directly determine the quality of nozzle to the height that storage facilities is required.The air velocity of two-phase flow atomizer in the market is provided mainly by the simple conversion of air pressure, and this mode causes the finite rate of air-flow, while also limit the jet length of drop;In addition, the current of common two-phase flow atomizer mainly provide pressure by air pressure to water storage apparatus, this puts forward higher requirement to water storage apparatus voltage endurance capability and sealing property, and the utilization rate that improve equipment cost and water is relatively low.
The content of the invention
The invention provides a kind of utilization low-pressure gas provides the new two-phase flow atomizer of power injection water mists, solving the technical scheme that its technical problem adopted is:High-speed jet is formed using low-pressure gas Jing reducing and expansion types jet pipe, jet forms negative pressure in hybrid chamber, water at atmospheric pressure is sucked into hybrid chamber, air-flow and current form emulsion after hybrid chamber mixing, and emulsion sprays again from jet expansion, forms water mists.
Description of the drawings
With reference to the accompanying drawings and examples the present invention is further described.
Fig. 1 is the structural representation of nozzle.
Fig. 2 is converting interface structural representation
The implication of reference is in figure:Nozzle exit end 1;Hybrid chamber 2;Laval nozzle supersonic speed expansion segment 3;Laval nozzle subsonic speed contraction section 4;Entrance stable section 5;Water-supply-pipe converting interface 6.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
Refer to Fig. 1, Fig. 2, a kind of straight line low pressure water mists reducing and expansion type nozzle with gas-liquid mixed chamber of the present invention, wherein, entrance stable section has internal thread for appendix connection;Hybrid chamber 2 is blind cylindrical hole, and there is internal thread bottom for being connected with water-supply-pipe converting interface 6;Nozzle exit end 1 is cylindrical hole;The water-supply-pipe converting interface 6 is connected by screw thread with hybrid chamber 2.
Refer to Fig. 1, Fig. 2, the operation principle of the present invention:Low-pressure air current enters nozzle by entrance stable section 5, after Laval nozzle subsonic speed contraction section 4 and Laval nozzle supersonic speed expansion segment 3, air velocity reaches supersonic speed, ultrasonic air-flow produces negative pressure by hybrid chamber 2, current self-priming is set to enter hybrid chamber 2, the strong impact in hybrid chamber 2 of current and air-flow, collision carries out air water emulsification, its viscosity of emulsion after emulsification and surface tension are all significantly less than the viscosity and surface tension of water, emulsion itself has very strong unstability, slightly disturbance will UNSTABLE FAILURE, certain pressure is assembled and kept to emulsion in hybrid chamber 2, then spray from the port of export 1 of nozzle head, secondary impact is carried out with air form water mists.
It is characteristic of the invention that atomized water spray distance is remote, atomizing effect is good, and the utilization rate of water is high and gas pressure belongs to low pressure range, and water is in atmospheric pressure state, gas storage water storage apparatus is required relatively low.

Claims (2)

1. a kind of straight line low pressure water mists reducing and expansion type nozzle with gas-liquid mixed chamber, is characterized in that:Using Laval nozzle technology, the gas flow rates of atomizer and the range of water droplet are improved.
2. reducing and expansion type nozzle according to claim 1, it is characterised in that:With Bernoulli effect, high velocity air forms negative pressure and normal pressure current self-priming is entered into hybrid chamber in gas-liquid mixed chamber, reduces the requirement to water storage apparatus, reduces cost.
