Description

Mesopore aerator

Technical field

The utility model belongs to water-treatment technology field, and in particular to a kind of mesopore aerator.

Background technology

Aerating system is one of key link in sewage disposal process, and exposure is delivered compressed air to by blower system In gas pond, oxygen is set to be sufficiently mixed with sewage by various types of aerators, microorganism is decomposed after absorbing oxygen in aeration tank Dirty Organic substance in water, reach the effect of purification of water quality.Bubble caused by the tolerance diffusion of unit volume is more, gas and liquid Contact area is bigger, and the efficiency of oxygen transmission is also higher.Therefore the quality of aerator and the quality of running situation, direct shadow Ring to the efficiency of sewage disposal, running expense, safeguard complexity.Current existing disc type or circular pipe type aerator use one section After time, venthole is easily blocked by sludge or debris, and being at this moment aerated efficiency reduces, it is necessary to which aerator is changed in cleaning.

Utility model content

The utility model is directed to weak point of the prior art, there is provided a kind of mesopore aerator.

The purpose of this utility model is realized in the following manner：

Mesopore aerator, including aeration tube, one end of aeration tube are provided with air inlet, and the other end is closed, and the two of aeration tube The top of side offers some first solarization air caps, and the bottom of the two sides of aeration tube offers some second solarization air caps, aeration Aeration elongated hole is offered on the bottom surface of pipe.

The diameter of second solarization air cap is more than the diameter of the first solarization air cap.

The cross section of the aeration tube positioned at the rectangle of centre and symmetrical two circular arcs at rectangle both ends by forming.

First solarization air cap and the second solarization air cap are arranged at intervals.

The quantity of first solarization air cap is 7, and the quantity of the second solarization air cap is 6.

The length of the aeration tube is 600mm, a diameter of 6mm of the second solarization air cap, a diameter of 4mm of the first solarization air cap.

The utility model is with the obvious advantage compared with the aerators such as disc type, circular pipe type：

1st, whipping performance is good；Whole mesopore aerator, is 360 degree and punches, in the absence of aeration dead band.

2nd, the expense of section of tubing is saved；Mesopore aerator construction costs will be significantly lower than the aeration such as disc type, circular pipe type Device.

3rd, when aeration, mud can be only deposited in the range of bottom of the tube very little, because the elongated hole of exhaust is arranged at bottom, only There is heavy mud on a small quantity the part of non-perforate.When being again started up, vibration caused by air blower air inlet can just shake mud and rapidly Stirring.So in the various sewage treatment process such as MBBR, MBR, SBR, CASS, it is very aobvious using the advantage of mesopore aerator Write.

4th, require very big in aeration quantity, in the case that pond face area is relatively small, could only be expired using mesopore aerator Sufficient technological requirement.

Brief description of the drawings

Fig. 1 is profile of the present utility model.

Fig. 2 is front view of the present utility model.

Fig. 3 is upward view of the present utility model.

Wherein, 1 is air inlet；2 be aeration tube；3 be the first solarization air cap；4 be the second solarization air cap；5 be aeration elongated hole.

Embodiment

As illustrated in the accompanying drawings from 1 to 3, mesopore aerator, including aeration tube 2, one end of aeration tube 2 is provided with air inlet 1, another Hold closed, the top of the two sides of aeration tube 2 offers some first solarization air caps 3, and the bottom of the two sides of aeration tube 2 offers Some second solarization air caps 4, aeration elongated hole 5 is offered on the bottom surface of aeration tube 2.

The diameter of second solarization air cap 4 is more than the diameter of the first solarization air cap 3.

The cross section of aeration tube 2 positioned at the rectangle of centre and symmetrical two circular arcs at rectangle both ends by forming.

First solarization air cap 3 is arranged at intervals with the second solarization air cap 4, as shown in Figure 2.

The quantity of first solarization air cap 3 is 7, and the quantity of the second solarization air cap 4 is 6.

The length of aeration tube 2 is 600mm, a diameter of 6mm of the second solarization air cap 4, a diameter of 4mm of the first solarization air cap 3.

The utility model is a kind of more novel aerator in sewage disposal, and the device aeration bubbles diameter is small, gas Liquid level product is big, and bubble diffusion is uniform, will not typically produce eyelet clogging, and corrosion resistance is strong, is applicable to municipal sewage, In the Air Exposures such as large and small type factory is newly-built, enlarging and old aeration tank are transformed, and aeration tank can intermittent duty.

The course of work of the present utility model is as follows：When air blower starts, gas is assigned to each aerator by supervisor Interior, aerator first passes through the first solarization air cap 3 and carries out uniform aeration, because the reason for pressure, when the first solarization air cap 3 can be aerated When, gas preferentially can emerge from the first solarization air cap 3, and only when the first solarization air cap 3 blocks, gas just can be from the second solarization air cap 4 emerge；

Using, when the first solarization air cap 3 has Partial Blocking, gas pressure is just downward liquid in aeration tube 2 after a period of time Pressure, until the second solarization air cap 4 is aerated, it ensure again that the stability and uniformity of aeration；After using the several years, having can Also there is stopping state in the second solarization air cap 4 of energy, then air pressure continues to press to bottom aeration elongated hole 5, and bottom exposes Gas elongated hole 5 never blocks, therefore can guarantee that this aeration tube never with replacing.

Mesopore aerator is applied in sewage disposal process in the sewage disposal device of increase sewage oxygen content.It is simple next Say, be exactly the pipeline of a connecting fan, have solarization air cap on pipeline, as the product of modernization science and technology, mesopore aerator has Oxygen supply uniformly, the characteristics of energy consumption is low, oxygen utilization rate is high, the high-performance of mesopore aerator with the addition of very important for waste water control Power-assisted.Mesopore aerator is diffused using bubble floating power makes bubble breaking attenuate, and can both reach higher oxygen profit With rate, it can meet that technology reasonably requires again, technical performance is very reliable.

Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as The scope of protection of the utility model.
