Description
Technical field
The invention belongs to heat supply, refrigeration, water supply, purification techniques fields, and in particular to one kind is suitable for exhaust liquid and decontaminates
The DNA double spiral micron order filter core of excellent.
Background technology
It, can be to pipe-line system top since gas density is low when entrained gas in liquid conducting pipes system
Aggregation, and increasing with gas, pipe-line system top air pressure can increase, under the liquid level so as to cause liquid in pipe-line system
Drop.In order to which liquid level is prevented to decline, it will usually automatic exhaust steam valve is installed at the top of pipe-line system, gas is discharged by automatic exhaust steam valve
Body, to reduce the air pressure at the top of pipe-line system.Stereo metal silk filter core is the core component for being vented decontamination apparatus, is directly related to
Exhaust scavenging effect, the resistance to water-flow of decontamination apparatus are vented, is directly related to the performance of product.Stereo metal silk filter core
Internal structure is designed exclusively for exhaust decontamination apparatus, should ensure have enough density to be used for dividing the stream that flow changes water
Dynamic state, reduces pressure drop, while have good self-cleaning ability again as far as possible again, is rapidly separated the bubble that captures and miscellaneous
Matter.
At present, the exhaust decontamination apparatus of domestic and international producer's production mainly has stainless steel filtering net, irregular metal strainer, copper mesh
Filter core etc. serves as filter core.Stainless steel filtering net is that planar structure is not for exhaust decontamination apparatus design, and performance has
Limit；Irregular metal strainer considers net rate density, but resistance to water-flow is larger, increases the energy consumption of degassing system.Also portion
The copper mesh filter core that man of subsidiary factory makes, only simple welding, not from the surface area of the resistance of fluid, surface tension and strainer
The problems such as consider, cause copper mesh filter cartridge construction is single, frame loosely, poor processing effect, it is impossible to meet various fluids within pipes
Exhaust decontamination.
The present invention has considered the influences such as the mechanical property of fluid, the space structure of resistance and strainer, surface area row
The element factor of gas is surface modified using copper alloy silk material matter as strainer, and to it, uses for reference DNA double helical structure, right
Filter screen and central shaft tube carry out double-screw type welding.Filter core is streamlined, reduces the resistance of fluid；Filter cartridge construction stabilization,
Surface area is big, enhances exhaust dirty removal capacities, and can realize the large-scale production of DNA double spiral shell micron order rotation filter core.

It is 70 ~ 80, preferably 73 ~ 78.
The present invention dominant mechanism be：The process being vented in a liquid is according to Henry's law principle：Gas is in liquid
Solubility is inversely proportional with temperature, is directly proportional to the pressure.The DNA double spiral micron order filter core of the present invention is by copper alloy silk and copper alloy
Hollow tube forms, and makes double-spiral structure, into streamlined, hardly generates pressure drop；Double-spiral structure copper alloy filter simultaneously
Net passes through surface modification, and to increase its surface area, fluid generates opposing stationary region internal, stops fluid stream as rapids
Stream, fluid encounters double helix filter screen, liquid levels made to become curved surface, and surface tension is caused to become larger, in liquid microbubble due to
Molecular action is largely gathered on the oblique cubic structure strainer of the larger double helix of surface treated surface area, and minute impurities are due to it
Difference in specific gravity is deposited in bottom from fluid, so as to play the effect of exhaust decontamination.
The DNA double spiral micron order filter core of the present invention has the advantage that：
（1）DNA double helical structure is relatively more firm；
（2）The surface of DNA double spiral has larger surface area into after surface modification；
（3）Hardly pressure drop is generated to system；
（4）Microbubble is easily assembled in liquid, and exhaust efficiency is high；
（5）Small magazine particle volume is collected in liquid, and filth-discharging effect is good.
