Description
Technical field
The present invention relates to the water-treatment technology field such as circulating water treatment, sewage disposal, be specifically related to a kind of aqueous vapor impurity and divide
From device.
Background technology
Aqueous vapor trash eliminator refers to the equipment that can be separated by the impurity in water with gas.
The Chinese patent literature of Publication No. CN203108383U discloses a kind of trash eliminator, including a three-way body
(1), it is characterised in that the Single port at three-way body (1) connects a separator body (2), arranges one point in body (2)
Off-network (3), arranges pair of magnetic assembly (4) on the body outer wall at corresponding separate mesh (3) position；Its advantage is, this impurity
Separator is applied in air-conditioning or refrigeration plant, can the minute impurities of the air entrainment from extraneous intake line system be entered
Row separates, and the impurity particle occurring chemical reaction to generate can be separated removing in the lump.Minimizing equipment is contaminated or stifled
The probability of plug, ensures the properly functioning of equipment, the service life of extension device.
The Chinese patent literature of Publication No. CN202962034U discloses a kind of pipeline trash eliminator.This pipeline impurity
Separator includes casing, and in two sidewalls that casing is relative, wherein side is provided with water inlet, and opposite side is provided with sewage draining exit and water outlet
Mouthful；Box house is by being divided into impurity range and clean area for the filter screen of impurity screening；Water inlet and sewage draining exit are in miscellaneous
In matter district, water outlet is in clean area；The sealing device for closing sewage draining exit it is provided with outside sewage draining exit；The extension of filter screen
Direction is inclined to set relative to the axis of water inlet, and by described water inlet, along its axis to the opposite side of described casing
Impurity range, filter screen and clean area is sequentially passed through during extension.After opening sealing device, utilize the thrust of current will pile up
Impurity in impurity range is released by sewage draining exit, and washes away filter screen simultaneously, just makes all quilts of the impurity on impurity range and filter screen
Remove；Reclose sealing device afterwards just can be continuing with.
Existing aqueous vapor magazins' layout has the disadvantages that
1, the impurity particle diameter that eddy flow aqueous vapor trash eliminator of the prior art filters is the most single, and a kind of model is only
The impurity particle of a kind of diameter can be filtered, if filtering the granule of minor diameter, arising that the bigger pressure loss, and having the biggest
It is likely to result in the phenomenon of blocking, and then makes device lose effect the danger causing blood circulation to stop.And aperture of filter screen list
One, get rid of the Air Bubble Size in recirculated water the most single, it is not the most thorough for causing the gas in recirculated water to get rid of.
2, importing and exporting position and be arranged on sustained height, current flow process is short, in fact it could happen that gas and Impurity removal be not thorough, and
Impacting with high pressure long to filter element, the service life of shortening device.
3, existing eddy flow aqueous vapor trash eliminator uses mechanical blowdown mode, and is manual form,
Blowdown easily occur not in time, blowdown the most thoroughly causes the possibility of circulation water pollution.After there is also blocking simultaneously
Also want the trouble of disassembly, cleaning.
4, existing eddy flow aqueous vapor trash eliminator, needs to discharge substantial amounts of water when carrying out impurity removing, causes water resource
Waste, and cause its applicable surface very to limit to (such as cannot be used in glycol system).
