Description
Technical Field
The utility model relates to a liquid hoisting device for sewage treatment field, especially a high-efficient formula air lift pump and the part that looses flows.
Background
The air lift pump is a device which takes gas as a power source and utilizes the principles of aerodynamics, hydromechanics and the like to realize fluid delivery. The only power of the gas stripping pump is provided by compressed gas, and the compressed gas is injected into the lifting pipe and generates bubbles, so that on one hand, the bubbles in the pipe rise rapidly to push liquid in the pipe to move upwards; on the other hand, the density of the mixed liquid containing bubbles in the tube is much lower than that of the liquid outside the tube, and the resulting pressure difference forces the fluid outside the tube into the tube and upward. The air lift pump has simple structure, no transmission parts inside and convenient use, so the air lift pump has wide application in the fields of excavation, sewage treatment and the like.
The prior air stripping pump has the following defects: a conventional air lift pump has an air tube extending into the center of the lift tube. For example, the Chinese utility model (No. CN 205013396U) relates to an air lift pump, which can achieve the purpose of lifting liquid by accumulating air mass in an air storage tank and then releasing the air mass instantly to form an air column, and the air column ascends to push the liquid in the pipe to do ascending motion. There are problems in that: the gas flow creates a column of gas or large non-uniform bubbles within the riser. Because the buoyancy of the air column or the large bubbles is far greater than the friction force generated by the surfaces of the bubbles and the liquid, the air column or the large bubbles can easily rise automatically and quickly, so that the lifting efficiency is low and is only 25-35%. The other is a high-efficiency air lift pump (such as Chinese utility model No. CN 208073884U) using micro-nano bubbles, which uses a micro-nano air distributor to form micro-nano bubbles in a pipe to be fully mixed with liquid, for the air with the same volume, the surface area of a large number of micro bubbles is larger than that of large bubbles, so that the surface friction is larger, the bubbles lift the liquid together, and the air utilization rate is high. The disadvantages of this technique are: firstly, the resistance of the micro-nano gas dissolving plate is reduced, which is not beneficial to energy conservation; and secondly, the micro-nano air dissolving plate is easy to block, and has large workload and high cost in maintenance and replacement. In addition, according to the stokes law, the rising speed of the bubbles in water is in direct proportion to the square of the diameters of the bubbles, the rising speed of the micro-nano bubbles is very slow, the lifting force of the bubbles to liquid is basically lost, a large amount of energy is lost when the gas is converted into the micro-nano bubbles, and the lifting efficiency cannot be well improved.
