Abstract
The utility model relates to a liquid lifting device, concretely relates to air lift. Its structure includes the vertical liquid lifting pipe of arranging in the liquid storage pot the bottom of liquid lifting pipe is equipped with the gas holder, the top and the compressed air ascending pipe of gas holder are connected, the bottom of gas holder and the liquid of liquid storage pot intercommunication, liquid lifting pipe is located the branch pipe that is equipped with on the inside body of gas holder with gas holder upper portion gas space intercommunication. The utility model discloses a what the air was rolled into a ball in the gas holder gathers and releases the efficiency that improves air lift, and reduces the energy consumption.
Description
Technical field
The utility model relates to lifting device for liquid, is specifically related to a kind of air lift with special construction.
Background technique
Air pump is gas pump again, usually for cesspool to extract mud or sand setting, also can be applied in fishery and agricultural, and be widely used in toxic fluid process, biochemical reactor design and nuclear industry fluid treatment in.
Typical extract air pump is exactly an extract pipeline vertically inserting in liquid, and its unique power is exactly the pressurized air provided by compressor.Pressurized air injects from the bottom inlet of extract pipe under liquid, produces a large amount of bubble in the liquid in pipe.Because the averag density of the liquid of pipe contain air bubble is more much lower than the density of the bubble free liquids outside pipe, therefore, on the one hand, in pipe, the rising of floating rapidly of bubble can promote liquid in pipe and also do ascending motion, on the other hand, on bottom inlet cross section, in pipe, the pressure of fluid column to this cross section of band bubble is significantly less than the outer bubble free liquids of pipe to the pressure in this cross section, can cause managing outer liquid to be inhaled in pipe by this entrance section, and upwards flow.As long as the air mass flow injected continuously is enough large, the outer liquid of this pipe to enter in pipe and just can recur along riser moving upwards, the pump action of maintenance continus convergence liquid.
The maximum advantage of air pump is that its structure is simple, does not have moving parts.But it also has following obvious shortcoming: the low lift that causes of suction is low; Flow rate of liquid is unstable and restive; Riser requires diving rate greatly and easily blocks, and diving rate is the ratio of the height of water in the water-immersed height of riser and riser; The utilization ratio of compressed air energy is low, causes energy consumption large.
Model utility content
The purpose of this utility model is the defect for prior art, provides a kind of air lift of special construction, to improve the efficiency of air lift, and reduces energy consumption.
The technical solution of the utility model is as follows: a kind of air lift, comprise the vertical liquid carrying riser be placed in liquid container, be provided with gas holder in the bottom of described liquid carrying riser, the top of described gas holder is connected with pressurized air ascending pipe, the bottom of gas holder and the fluid connection of liquid container; The body being positioned at gas holder inside at described liquid carrying riser is provided with the arm be communicated with gas holder upper gas space.
Further, air lift as above, wherein, described arm comprises the horizontal pipe and a vertical tube that are interconnected, and described horizontal pipe is connected with described liquid carrying riser, and described vertical tube is positioned at immediately below described pressurized air ascending pipe.
The beneficial effects of the utility model are as follows: the air lift of special construction provided by the utility model, by in gas holder inner accumulated air bolus, then abrupt release forms taylor bubbles, solve dissolver and put forward in slag process the problems such as the easy obstruction, the pulling force that run into be low, both improve the efficiency of slag, in turn save energy consumption.
Accompanying drawing explanation
Fig. 1 is the air lift structural representation of the utility model specific embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Figure 1 shows that the air lift of the special construction be arranged in a liquid container 2.This air lift is made up of a gas holder and some pipelines.Wherein, what liquid carrying riser 1 was vertical is installed in liquid container 2, is provided with gas holder 4 in the bottom of described liquid carrying riser 1, and the top of described gas holder 4 is connected with pressurized air ascending pipe 3, the bottom of gas holder 4 and the fluid connection of liquid container 2.Gas holder 4 inside has an arm 5 be connected with liquid carrying riser 1, and arm 5 is communicated with gas holder upper gas space.In the present embodiment, arm 5 comprises the horizontal pipe and a vertical tube that are interconnected, and described horizontal pipe is connected with described liquid carrying riser 1, and described vertical tube is positioned at immediately below described pressurized air ascending pipe 3.
Pressurized air injects in gas holder shell by the pressurized air ascending pipe of the air lift of this special construction, the pressurized air entered in gas holder shell can not be released to vertical liquid carrying riser at once, but accumulate in shell, at this moment there is an air bolus in shell and inner pipe fitting.When the air in shell runs up to a certain degree, the air bolus of a large volume is discharged in vertical liquid carrying riser at once, forms a diameter and equals bore and very long columned Taylor (Taylor) bubble of axial length.Because Taylor (Taylor) bubble is that interval is formed, therefore the operation of this air lift is also step.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if belong within the scope of the utility model claim and equivalent technology thereof to these amendments of the present utility model and modification, then the utility model is also intended to comprise these change and modification.
Claims (2)
