Description

Novel metal film filter

Technical field

This utility model is related to water treatment facilities, specifically a kind of novel metal film filter.

Background technology

Traditional wastewater, drinking water three-stage filtration technology are with the powder sintered ceramic membrane of the netted fine ceramic of multilamellar Or with the higher titanium of purity as the three-stage filtration equipment of sewage or drinking water filtrate, it is important that removing sewage or drink With small float and nominal particle size material in water, while the Organic substance, oils and fatss to macromole carries out isolation removal, can make Sewage quality reaches stratum re-injection or is discharged to outward the standard in inland, makes drinking water reach the standard directly drunk.But both materials The filter of material all has that cost is higher, technology is unstable, the risk that life cycle is short.

Ceramic powders filtering material filter air permeability is low, and the powder channel space of sintering is uneven, and filter pressure is big, backwash Pressure is big, and the power of corresponding device, discharge capacity are larger, and backwash effect is also thorough, therefore the water process of unit volume filter Ability is less, and the expense of investment and day-to-day operation is of a relatively high；Meanwhile, the bubble point pressure that ceramic powders filtering material filter bears Relatively low, fragility is larger, broken, fracture, so as to affect the water quality index of whole system.

The higher titanium metal film filter of purity, its space uniformity, filter pressure, backwashing pressure are relatively Low, the pressure in bubbles that metal film can bear is higher, and toughness, stretch capability are stronger, not cracky, fracture, water stabilization；Uniquely Have the disadvantage that cost is high, the more stable metal film of domestic market sewage, drinking water Fine Filtration Technology is almost state The shaping membrane of outer import, purchase cost are very high, and procurement cycle is long, and after-sale service cannot ensure.

Utility model content

The purpose of this utility model is exactly to overcome the deficiencies in the prior art, there is provided a kind of novel metal membrane filtration Device.Solve the frangible easy fracture of conventional filter, conventional filler and unstable membrane filtration space, filtration and backwash power easily occur The high titanium metal film filter purchase cost of equipment highly energy-consuming, purity is high, procurement cycle is long, and what after-sale service cannot ensure asks Topic.

In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals：

Filtered water inlet pipeline, backwash are provided with from top to bottom in a kind of novel metal film filter, including tank body, the tank body Water outlet pipeline, water pipeline, backwash back with water inlet line are filtered out, the filtered water inlet pipeline passes through Pneumatic butterfly valve with backwash water outlet pipeline Connection；The water pipeline that filters out is connected by Pneumatic butterfly valve with backwash back with water inlet line；Connect blowdown pipeline below skirt；Tank body Inner top is provided with water knockout drum；The filtered water inlet mouth being connected with water knockout drum is provided with outside tank body；Filter out The mouth of a river is leached, water pipeline is filtered out and is provided with remittance liquid pipe and collector tube；Blow-off pipe is placed in below skirt, is connected with blowdown pipeline； Metal film is hung with radial parallel, vertical demixing and is installed in tank body with filter center line as axle center.

Using above-mentioned technical proposal this utility model compared with prior art, its advantage is as follows：

（1）Low cost of manufacture, is only the 60% or so of traditional three-level water filter manufacturing cost；Procurement cycle is short, is only to pass The 50% of system three-level water filter procurement cycle.

（2）Long service life, one times of at least traditional three-level water filter service life.

（3）Operating cost is low, filters power-equipment, the power consumption of backwash power-equipment and filters than traditional three-level water filter Power-equipment, the power consumption of backwash power-equipment are low by more than 30%.

（4）Regular maintenance cost is low, compared with traditional three-level water filter is filtered, the maintenance of novel metal film filter into This is the 20% or so of traditional tertiary filter maintenance cost；Separator interior can realize that 5-10 is non-maintaining.

Preferred version of the present utility model is as follows：

Sled block is set below blowdown pipeline.

Filtered water inlet pipeline is connected by 2 Pneumatic butterfly valves with backwash water outlet pipeline；Filter out water pipeline to intake with backwash Pipeline is by 2 Pneumatic butterfly valve connections.

Tank body top left side arranges a relief valve port.

Tank body top right side arranges a upper manhole.

Below tank body, left side is provided with observation panel and sled block 8 between.

Filtered water inlet pipeline and filter out between water pipeline left side and be provided with lower manhole.
