The pulse air lifting device applies theory of pressure difference between air pressure and pressure of lifted materials, adopts method of lifting some materials different from conventional air lifting theory, increases lifting power of solid-liquid mixture and meets requirement of lifting relatively large solid particles. The pulse air lifting device has the advantages of simple operation, stable running and wide applicability in lifting various liquids or solid small particles at bottom portion of the liquids.

Description

The pulse air-lift device

Affiliated technical field

The utility model relates to a kind of gas lift device, particularly a kind of solid granule that is used for interior liquid of hoisting container or liquid in container bottom.

Background technology

Present widely used air-lift device is conventional air-lift device, and conventional air-lift device principle is as follows:

After gas is passed into the riser bottom, bubble is because buoyancy meeting rising, rising along with bubble, bubble can be full of whole riser, it in the pipe mixed solution of gas and liquid, pipe is outer to be liquid, the density of gas-liquid mixed solution is less than density of liquid (the general relative minimum density of gas-liquid solution is about 0.25-0.35), just there has been pressure differential the pipe bottom, the gas-liquid solution interface that density is little can raise, and in the time of making gas-liquid solution rise to certain height, air-lift device must have certain depth of immersion, and need a certain amount of compressed air of supply, so that the density of gas-liquid solution reaches smaller value.The required lifting height of gas-liquid solution is big more, and the density of gas-liquid solution just should be more little, and the tolerance that needs is also just big more, and depth of immersion is also just big more.Therefore, conventional air-lift device roughly has following shortcoming owing to its principle, structural reason:

1. lifting force is less than normal, is generally 60% of riser bottom pressure that liquid medium produces;

2. don't fail to reach certain rate of flooding (60%) could work effectively;

3. when tolerance reached a certain amount of, fluid flow can descend.

These shortcomings have had a strong impact on the result of use and the scope of application of air-lift device, have brought a lot of inconvenience in daily use.

Summary of the invention

At above-mentioned the deficiencies in the prior art, it is big that the purpose of this utility model provides a kind of lifting force, and the rate of flooding is low, the gas lift device that fluid flow is big.

A kind of gas lift device, comprise riser 1, atmosphere chamber 2, stingy chamber 3 and air inlet pipe 4 composition gas lift devices, it is characterized in that: atmosphere chamber 2 and the 3 reverse placements of stingy chamber and stingy chamber 3 are positioned at atmosphere chamber 2, form air chamber, air chamber and the riser that axially passes therethrough are formed whole gas lift device.Wherein open an aperture on the tube wall of riser 1, this aperture is positioned at the bottom of stingy chamber 3 and close little air cavity; Atmosphere chamber 2 is made up of chamber tube and base plate, and a hole is arranged on the base plate; Stingy chamber 3 is made up of chamber tube and base plate, and a hole is arranged on the base plate; Air inlet pipe 4 adopts the pipe fitting that has external pipe thread or flange, and the connection of each part all will seal air tight.

The utility model has the outstanding advantage of following several respects owing to adopted above technical scheme:

(1) can under stingy flow, work;

(2) lifting force greater than in the conventional air-lift device since pressure that density contrast produced be twice approximately;

(3) the pulse air-lift device is easily adjusted flow rate of liquid by control tolerance, and conventional air-lift device then is difficult to adjust flow rate of liquid by control tolerance;

(4) the pulse air-lift device goes for very little flow, and conventional air-lift device then can not;

(5) under perfect condition (the riser inwall is definitely smooth, air tight etc.), the pulse air-lift device can be carried liquid to infinite height, and just this moment, fluid flow was too little;

(6) in conventional air-lift device, riser diameter is big more, and the ratio of throughput and fluid flow is more little, i.e. energy waste many more, and the pulse air-lift device does not then have this shortcoming;

(7) rate of flooding of conventional air-lift device must reach at 60% o'clock could operate as normal, this has seriously limited its scope of application, has especially limited hoisting depth, and the pulse air-lift device hardly the rate of being flooded limit;

(8) conventional air-lift device is prone to clogging, and the pulse air-lift device can not cause the liquid volume expansion because bubble and liquid do not mix, and the lifting force of pulse air-lift device is much larger than the lifting force of conventional airlift pump, thereby clogging can not occur;

(9) except promoting various mixed liquors, the pulse air-lift device can replace axial-flow pump and mixed-flow pump in some aspects, can be used for deep-well water intaking in addition, oil well is got wet goods.

The specific embodiment

Below in conjunction with embodiment and relevant accompanying drawing design feature of the present utility model and operation principle thereof are described in detail as follows:

As shown in the figure, gas charges into the atmosphere chamber 2 that sealing lower end, a upper end is opened wide, riser passes from its center, in atmosphere chamber, there is the upper end to open wide the stingy chamber 3 of lower end sealing, same riser passes from its center, after gas is charged into atmosphere chamber 2 and stingy chamber 3, liquid can be arranged in the air cavity, pressure in the air cavity can increase, during fluid column produced in greater than riser 1 pressure, bubble can be released in the riser 1 via the aperture on the riser 1 in atmosphere chamber 2 and stingy chamber 3 in the extremely short time, bubble is released fluid column outside the pipe then, controls the speed that bubble enters riser by the speed that the control bubble produces, and then can control the flow of liquid.

The utility model course of work is: before the art inflation, all be liquid in riser 1, atmosphere chamber 2 and the stingy chamber 3, along with charging into of gas, liquid in the atmosphere chamber 2 is discharged from from lower ending opening, liquid in the stingy chamber 3 is discharged from from the aperture on the riser 1 that is positioned at its next door, bottom, when liquid level dropped to the position of this aperture in the stingy chamber 3, the pressure in the air cavity equaled the pressure that aperture place liquid gravity is produced; Continue inflation, pressure can increase in atmosphere chamber 2 and the stingy chamber 3, greater than the liquid pressure at aperture place, gas will enter riser 1 from aperture like this, cuts off the fluid column in the riser 1, form bubble, the pressure of this bubble is greater than the gravity of bubble top fluid column, so along with continuing inflation, bubble enlarges, just pushing away fluid column and rising, outside discharge pipe.Fluid column be discharged from the pipe outside at that moment, the above that part of pressure in riser 1 inherent aperture place is atmospheric pressure, this moment, the pressure differential at aperture place just was the pressure that liquid depth produced, this pressure will push away riser 1 outer liquid and solid granule and enter riser 1 from 1 end of riser mouth, released outside the pipe by next bubble, so just finish promote liquid with and the process of bottom solid granule.
