Abstract
The invention discloses a defoaming device, which damages foams and achieves the effect of gas-liquid separation depending on the defoaming effect of meshes. The defoaming device consists of a cylinder body, a water baffle plate, stainless steel meshes, a baffle board and a water injection pipe, wherein an upper layer of stainless steel mesh and a lower layer of stainless steel mesh are arranged on the middle part of the cylinder body; the water injection pipe is arranged above the two layers of stainless steel meshes; the water baffle plate is arranged above the water injection pipe; the baffle board is arranged above the water baffle plate; and a water discharging pipe is arranged in a water collecting tank on the lower part of the cylinder body. Separated liquid falling into the water collecting tank at the bottom of the defoaming device enters the water discharging pipe and is discharged out of the defoaming device under certain pressure at regular time. The defoaming device is widely applied to the defoaming of aeration tanks in a water treatment process.
Description
Technical field
The present invention relates to a kind of defoaming device, especially a kind of froth breaking effect that relies on mesh makes foam destroy and reach the defoaming device of gas-liquid separation effect.Be applied to water treatment field.
Background technology
Be easy to produce foam in the water treatment facilities, particularly be easy to produce foam in the aerobic biochemical aeration tank.Modern age, printing and dyeing industry was at chemical sizwe and various surfactants such as a large amount of use polyvinyl alcohol, a large amount of foams of the frequent generation in aeration tank in treatment of dyeing wastewater.Not only influence view, and influence the operation of water treatment facilities.Artificial for the expense of defoaming very, adopt defoamer froth breaking expense very high, and defoamer itself also is a kind of polluter, increase the load of water treatment facilities.When needs extract contain bubble gas enter follow-up equipment process, when handling, foam that gas is entrained and droplet can influence the work of follow-up equipment, even make follow-up equipment to move.At present, can not find suitable defoaming device complete set of equipments on the market, need development a kind of easy to use, simple in structure, the defoaming device that operating cost is low.
Summary of the invention
The present invention has the principle of froth breaking effect according to mesh, in the defoaming device cylindrical shell, lay the double-layer stainless steel net, utilize the froth breaking ability foam that gas is entrained of mesh to convert liquid to, wherein the liquid of big particle diameter will be owing to the gravity effect, and the water leg that falls into the defoaming device bottom enters outlet pipe and discharges defoaming device.There are water fender and reflecting plate in the stainless (steel) wire top, will be held back by water fender and reflecting plate in the gas-liquid separation section owing to carrying secretly of gas acts on the small particle diameter drop that continues to residue in the gas, thereby remove entrained foam of gas and droplet all sidedly.
In addition, because entrained foam of gas and droplet can contain pollutant and impurity to some extent, can stop up folding net mesh after the long-time running, and corrosion is caused in contaminated equipment inside, the sparge pipe that is provided for cleaning in froth breaking stainless (steel) wire and gas-liquid separation section utilizes clean water at the initial stage that equipment is stopped transport device interior to be cleaned up.
The parting liquid that falls into the water leg of defoaming device bottom enters outlet pipe and regularly discharge defoaming device under certain pressure.
The structure of a kind of defoaming device of the present invention is, defoaming device is made up of cylindrical shell, water fender, stainless (steel) wire, reflecting plate, sparge pipe, upper strata stainless (steel) wire and lower floor's stainless (steel) wire are laid in middle part at cylindrical shell, sparge pipe is arranged above two-layer stainless (steel) wire, there is water fender the top of sparge pipe, and reflecting plate is arranged above water fender.Air admission hole is in the lower side of cylindrical shell.Venthole has outlet pipe in the center of top of cylindrical shell in the water leg of cylindrical shell bottom.
The screen size of upper strata stainless (steel) wire is 1 millimeter～3 millimeters.
The screen size of lower floor's stainless (steel) wire is 2 millimeters～4 millimeters.
Spacing is 40～100 millimeters between upper strata stainless (steel) wire and the lower floor's stainless (steel) wire.
Water fender be shaped as inverted round platform, the last bottom perimeter of round platform and cylindrical shell welded seal, the following bottom perimeter of round platform forms a circular channel.
Reflecting plate is a conical plate, and its drift angle is the obtuse angle, and optimized angle is between 135 degree～155 degree, and reflecting plate is fixing by supporting rib and cylindrical shell welding.
Sparge pipe is a perforated pipe, and the preferred diameter of osculum is between 25 millimeters～40 millimeters.

The specific embodiment
Below in conjunction with accompanying drawing using method of the present invention is described further.
A kind of defoaming device of the present invention links to each other with water treatment facilities aeration tank 13, a large amount of foams that top, aeration tank produces enter from air inlet 5, the gas that has a large amount of foams that rises is upwards successively by lower floor's stainless (steel) wire 4 and upper strata stainless (steel) wire 3, because mesh has the froth breaking ability foam that gas is entrained and converts liquid to, wherein the liquid of big particle diameter will be owing to the gravity effect, the water leg that falls into the defoaming device bottom enters outlet pipe 9, and discharges defoaming device through trap 10.There are water fender 2 and reflecting plate 7 in the stainless (steel) wire top, is held back by water fender 2 and reflecting plate 7 in the gas-liquid separation section owing to carrying secretly of gas acts on the small particle diameter drop that continues to residue in the gas, thereby removes entrained foam of gas and droplet all sidedly.Gas after the separation is discharged from the gas outlet 6 at defoaming device top.
Because entrained foam of gas and droplet can contain pollutant and impurity to some extent, can stop up the stainless (steel) wire mesh after the long-time running, and corrosion is caused in contaminated equipment inside, the sparge pipe 8 that is provided for cleaning in froth breaking stainless (steel) wire and gas-liquid separation section utilizes clean water at the initial stage that equipment is stopped transport device interior to be cleaned up.
The parting liquid that falls into the water leg of defoaming device bottom enters outlet pipe 9, intermittently flushing process produce flushing water also enter outlet pipe 9, and under certain pressure, regularly discharge defoaming device.
Fig. 2 is a kind of defoaming device of the present invention and ozonation aerated pond coupling mode schematic diagram.Aeration tank 13 produces a large amount of foams in ozonation aerated process, the top seal of aeration tank 13, this defoaming device are installed on the top, aeration tank.Air inlet 5 is connected with the top, aeration tank by pipeline with trap 10.Gas outlet 6 connects by pipeline and other two auxiliary equipment gas treatment devices 11 air exhausters 12.The effect of gas treatment device 11 is water droplets of carrying secretly in the divided gas flow, and the effect of air exhauster 12 provides certain negative pressure, guarantees the normal operation of this defoaming device.
Defoaming device of the present invention is at water-treatment technology field, particularly adopts water-treatment technology fields such as ozonation aerated, various biofilters to be widely used.
