Abstract
The utility model relates to a high efficient blocking-proof aerosol releasing device for purifying industrial waste water in a flotation way. The high efficient blocking-proof aerosol releasing device is composed of an upper cover (1), a gap fixing ring (2), a spring (6), a screw nut (8) for pressure regulation, a socket (9), etc. Aerosol water flows into a gap and a space (11) through a small hole (10), the gap and the space (11) are formed by an umbrella-shaped conical surface of a lower cover (4), and the heights of the gap and the space (11) can be changed along the small peripheral radial direction. The aerosol water is uniformly diffused all around through water distribution holes (13), (14) of a casing (5). The utility model has the characteristics of short release path, high speed, small air bubble diameter, long stay time, uniform water distribution, high flotation efficiency, convenient operation, etc. In addition, the blocking can be automatically eliminated under the normal working pressure when impurities are clamped in the gaps. A dynamic check can be implemented under the condition of water discharge when the machine is not stopped.
Description
The utility model is in the pressure air-dissolving air-float method water-purifying process, particularly the dissolved air releasing device in the purified industrial waster water process.
As everyone knows, the pressure air-dissolving air-float method be purified industrial waste water important technical it can become the gas release in the pressure air-dissolving water fine intensive bubble population, and introduce in the processed trade effluent, float the upward water surface rapidly after making uniform contact such as bubble and oil, heavy metal flco, fiber, algae suspended substance, thereby reach the purpose of purification of water quality.In this process for purifying water, the key equipment that uses in the time length that microbubble stops in water and this technology--the relevant method that solves blockage problem in the dissolved air release, being the subject matter that people research and solve, also is the important symbol of decision air flotation effect.Chinese patent 87212732 has been introduced a kind of reliever, and it has solved some problems.But in use also exist not enough.The first, path length, the speed of dissolved air release are slow, and bubble diameter increases when mixing with waste water, the residence time is short, daf efficiency is relative not high; The second, the dissolved air water from ozzle ejection be the direct projection of single bundle, mix with waste water inhomogeneous; Three, because the slit is parallel, tamper can not be got rid of under service pressure automatically.
The purpose of this utility model is; design a kind of dissolved air, release way is short, speed is fast, bubble diameter is little, the residence time is long, water distribution is even, daf efficiency is high dissolved air release of making; main is can remove obstruction automatically when accompanying foreign material in the slit under service pressure; and can carry out dynamic check under the situation about discharging water not shutting down, easy to operate.
Now reach example in conjunction with the accompanying drawings structure of the present utility model and principle are described.
Fig. 1 is efficient anti-clogging plug dissolved air release structural representation.
Fig. 2 is the synoptic diagram of efficient anti-clogging plug dissolved air release on project installation.
In Fig. 1, umbrella lower cover (4) is installed in shell (5) the centre pilot hole, can do upper and lower moving axially along pilot hole.For limiting its mobile upper limit, in shell (5), be provided with ring groove than the middle part, its the mobile lower limit of snap ring (3) that is inlaid with opening in the groove is realized control by spring (6), taper pin (15), nut (8), after pressure and slit mix up, lock by setscrew nut (7), the lower end of nut (8) also is connected to inserted link (16), and effect is to insert to have in the socket (9) of bellmouth orifice.
Loam cake (1) is combined on the shell (5) by external thread rotary, and topmost car has screw thread or sawtooth button.Can distinguish socket hard tube or flexible pipe as required.The center is the limbers.Be aperture (10) bottom.Loam cake (1) makes it to have formed one with umbrella lower cover (4) and snap ring (3) with screwing of shell (5) and crosses hydrospace (11).It and slit height have directly gets in touch.That is to say the relation that a best slit is arranged between the umbrella vertex of a cone end of umbrella lower cover (4) and the aperture (10).The umbrella cone angle generally is controlled between 120 °～170 °.So the slit is that a height is to the slit that radially increases all around.Through design calculation, test, the top height in slit is controlled in 1～3 millimeter to well.For the ease of artificial this best slit of realizing, be provided with one especially and decide crack ring (2), it has close getting in touch with other parts on parameter designing.
Accompanying drawing 2 is the utility model scheme of installations on engineering.Socket (9) is fixed on the bottom of air flotation pool (20).Dissolved air release is installed on the socket (9) by inserted link (16).And by valve (19) UNICOM of flexible pipe (17) with the control dissolved air water.If will check the working order of reliever, as long as the operator stands in and mentions flexible pipe (17) on the workplatform (18) and just can propose reliever from water.Dynamically down checking, need not shut down or the emptying air flotation pool in water.
Gas releasing process is described below: pressure air-dissolving water flows into the slit height by valve (19), flexible pipe (17) through aperture (10) and radially becomes big space (11) gradually, because section became big suddenly when dissolved air water entered space (11), its flow velocity and energy were subdued significantly in moment.The gas that is dissolved in the water is separated out from water with molecularity rapidly, changes into the minimum microbubble of diameter.Transparent dissolved air water becomes milky outgas water.Since work medi-spring (6) vibration make separating out of gas molecule faster, more become thorough.Outgas water flows into lower cavity by the limbers (12) on umbrella lower cover (4) and the garden conical surface, behind the outgas that further reduces pressure, by the water distributing pore (13) on the shell (5), (14) uniformly to around spread in the processed water.
By above analysis, this novel dissolved air release has the following advantages:
1, the space (11) of the best chinky altitude of composition is subjected to the impact of umbrella lower cover (4) resemblance and becomes gradually big. When dissolved air water flowed out from aperture (10), the instantaneous change of its section was big, and flow velocity and pressure energy are subdued significantly. Being dissolved in gas in the water is transformed into the minimum microbubble of diameter with molecular state rapidly and separates out from water. This time course is extremely short. The bubble that produces has little time and greatly, and is very fine. After measured, d/d bubble can stop more than 5.5 minutes in 1000 milliliters of graduated cylinders. And the bubble that common release discharges stops about 3.5 minutes only. So greatly improved daf efficiency.
2, be subjected to dissolved air water from the effusive impulse force of aperture (10), spring (6) is in the low amplitude high frequency vibration all the time, impel gas release more abundant, speed is faster.
3, it is short that shell (5) is gone up the flow path that set circumferential water distributing pore (13) and lower curtate water distributing pore (14) make bubble, and the water distribution diffusion is even, and area is big, mixes with waste water.Can save the input amount of cohesion medicament.
Even 4 have dirt to stop up, because slit of the present utility model is not parallel.So it just has the function of the little tamper of automatic eliminating under service pressure.If there is bigger dirt to stop up the slit,, can produces hydraulic pressure and rise because dissolved air water is not smooth.This pressure is enough to make spring (6) compression, and the slit height is strengthened rapidly, and tamper just can be discharged.Latch up phenomenon is got rid of automatically with self structure and is restored to the original state.
5, the utility model is provided with socket (9).Make location, operation, inspection get up very convenient.And main is to have ensured the working order that is able to the dynamic check reliever under the situation of discharging water not shutting down.
