Abstract
The invention relates to a water treatment core part. The core part is arranged into a porous structure, the distribution condition of the porous structure is reasonably limited, and the material texture of the core part is improved, so that the water treatment efficiency is greatly improved.
Description
Technical field
The invention belongs to water treatment field and alloy field, more particularly to a kind of water process core component, particularly locate
Reason textile enterprise waste water, the water process core component of boiler feed water.
Background technology
With industrialization great development, water body environment is greatly challenged, in order to go back the more natural water body of the mankind one
Environment, has a lot of water treatment facilities at present.The wastewater treatment relative difficult of textile enterprise and similar enterprise.Have at present
Sewage treatment equipment is used copper alloy as core component, because its alloy surface can form the countless former of different potentials in water
Battery, forms huge high electric field in microcell, causes hydrone to produce resonance, polarization, and eliminates unnecessary surface charge,
Hydrogen bond is disconnected, so that water clusters is diminished, improve reactivity and the solubility to incrustation scale of water, reduce and separate out；Seldom adsorb
On dyeing machine, on textile, reduce wash number it is easy to cleaning, save a large amount of reduction cleaning chemical agents and surface
The consumption of activating agent；Reduce the activity of many prices metallic element ion, thus avoiding its impact to dyestuff.Conventional core
Part surface texture is groove structure, but because its contact area is relatively small, treatment effect is preferable not to the utmost, and researcher also has
Want to set up as honeycomb, but because wall portion is relatively thin, be easily broken off, therefore also do not find up till now to tie using honeycomb
Structure (loose structure).
Content of the invention
An object of the present invention is to propose a kind of core component of water process.

Reason controls the distributing position of different-grain diameter easy vaporization at high temperature material that aperture at surface is set greater than aperture at core.
After the Copper alloy bar shaping of described loose structure, through following Technology for Heating Processing:
1) Copper alloy bar is inserted resistance furnace, be warming up to 550 ~ 600 DEG C, be incubated 2 ~ 3.5 hours, then naturally cool to room
Temperature；
2) Copper alloy bar that step 1) obtains is placed in deep cooling treatment tank, cools to -80 ~ -120 DEG C, keeping temperature
After 18 ~ 25min, go out deep cooling treatment tank, recover to room temperature；
3) by step 2) Copper alloy bar that obtains inserts tempering furnace, and it is warming up to 160 ~ 180 DEG C, is incubated 55 ~ 80min, stove is cold
To room temperature.
Effect of the invention is that:
1, by arranging the Copper alloy bar of loose structure as the core component of water process, significantly increased and water
Contact surface area, what the efficiency of water process obtained increases substantially；It is more than the structure of core aperture by arranging surface apertures, make
All can efficiently water be processed at surface and core in water treatment procedure, it is to avoid at surface process more and at core
The problem that cannot be carried out processing；
2, adjusted by rational constituent content and rational heat treating regime foundation so that alloy strength and hardness
Be greatly improved, even if being set to loose structure, also will not local fracture and make impurities in water increase, also improve simultaneously
