Description

Dissolved gas floatator
Technical field
Suspended material present in liquid (being usually water) is entered by using air-dissolving air-float technology the present invention relates to one kind The device of row separation, and operation of the device in terms of fluid power is based on speed offset principle, and the principle is public in the art Know.In everyday practice, such device is referred to as " dissolved gas floatator ".The device can be used for purifying waste water.
Background technology
Air-dissolving air-float purification techniques uses air (or other gases) microbubble, and these microbubbles are attached to be present in and wait to locate The solid particle (suspended material) in water is managed to cause solid particle to rise to surface.Thus, pollution solid material is separated from water, So as to which water is cleaned, the solid matter is collected on surface.Each dissolved gas floatator includes two main elements.
First element is microbubble generation system, and the system constitutes the core of each air-dissolving air-float cleaning equipment.It is more general Everywhere, microbubble is obtained by making a part of purified water cycle through booster pump and forced air dissolver.Should be rich in molten The pressure (hydraulic) water of gas, which returns to atmospheric pressure, causes molten gas to be separated out in the form of microbubble.
Second element is groove, carries out the separation of polluter and water for physically in the cell.In the presence of comprising different Many structures of fluid power concept.The most common center that is used in has accessing pending water input port and is recycled to purified water outer The circular trough enclosed;Or use has accessing pending water input port in side and has the square of purification water output in opposite side Shape groove.In the case where not discussing the details of existing each fluid power concept, it is believed that the purpose of research is identical all the time, Ensuring the flowing of the water between input port and delivery outlet has turbulent flow as few as possible, to cause the separation of polluter and water Process can carry out closest in the state of laminar flow, and this is most fragile and fine purification process is opened for being proved to be Exhibition is clearly best.
Operation of the apparatus according to the invention in terms of fluid power is based on speed offset principle, by the structure for ensuring these functions Part offsets the boot speed of accessing pending water and the gathering speed of purified water respectively.The principle is applied to the equipment with circular trough. Accessing pending water is allocated by the radial device of the central rotation activity relative to groove, the water of its rotary speed and distributor Output speed it is identical, and the direction of rotation of radial device and the outbound course of water are opposite.In this way, two speed are mutual Offset (name for thus obtaining the principle), and each accessing pending water volume importeding into air flotation slot is remained stationary as and waited The recovery system of purified water is collected to it.Meanwhile, purified water passes through similar to accessing pending water gatherer and link Collected to the radial device of accessing pending water gatherer, the radial device is located at downstream relative to the outbound course of water.Change speech It, is not water is moved between input unit and output device (the two is fixed), but make the input unit and Output device depending on the speed of water-carrying capacity to move, make it that water is not moved but is rested on water and is imported into by input unit Groove in and wait output device to be collected it.The technology is known and for example in document US 4 022 It is described in 696.The technology has different known embodiments, wherein version the most advanced is with KWI International companies sell trade name Supercell and be known.Even if the known device is commercially achieved Huge success, but it result in the concept of fluid power and mechanical aspects and realizes that some relevant are asked with speed offset principle Topic.
In fact, same in view of its concept, distribution of the accessing pending water in the air flotation slot of these equipment passes through in groove Rotary engaging member at the heart is completed, and is connected to from air supporting bubble and is collected above central channel by and from activity after the fastener The pipe-line system passed through below buoyancy tank, the pipe-line system separates in air supporting region with purification water collecting groove, purifies water collecting groove Itself is located between the gentle floating bubble collecting tank in air supporting region.Above two grooves by certainty from the horizontal plane in the groove with And pass through above air supporting region.Square this rising needs extra supply pressure, the extra supply to water in the horizontal plane Pressure can only be relative to the potential energy of the horizontal plane in air supporting region.Compensation of the dispatching device to the potential energy causes very strong disorderly Stream.
Therefore, for small-size equipment, the potential energy is expressed as 20 to 30cm water column, and this shows as water in dispatching device Equipped at outlet port is with 1.4 to 1.6m Speed allotments per second.
For large scale equipment, the potential energy can reach 60cm water column, and this shows as the equipped at outlet port in dispatching device 2.4 to 2.6m speed per second.
It is apparent that being difficult compatible with desired effect with this speed injection accessing pending water, that is, set up and most connect with laminar flow Near flox condition.
Supporting and centring means that rotary components are arranged in the rotary engaging member requirement at equipment center are additionally, there are, this It result in substantial amounts of mechanical problem.
A kind of difference and advantageous approach for implementing speed offset principle is proposed according to the equipment of the present invention, set with known Standby to compare, this method makes it possible to solve the problems, such as most machinery and fluid power.
The content of the invention
According to the equipment of the present invention by the collection central channel of the air supporting bubble with air supporting bubble discharge line with being somebody's turn to do The accessing pending water rotation supply fastener of equipment is combined, and is enable to the water included in the major trough for constituting air supporting chamber Accessing pending water is imported below the surface of volume and around the air supporting bubble discharge line, accessing pending water is generally in the groove institute It is directed in the overall depth or height of the liquid of receiving in groove.
The concept is so that can:
- accessing pending water is supplied to groove with minimum pressure, to cause supply hydraulic measurement pipe to be no more than all the time in air supporting chamber Water upper plane.Therefore, the potential energy that supply belt is come significantly reduces, and this is equally reduced in distribution by the potential energy to kinetic energy It is inevitably turbulent caused by conversion (water in flotation cell declines again);
- simple fixed center is used to input unit and the swivel mount of the collection device of purified water including accessing pending water Bearing.
