Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses biological purification device's gas distribution device. Referring to fig. 1 and 2, the air distribution device of the biological purification device comprises an air distribution disc 1, the air inlet pipe 2 is communicated with the center of the air distribution disc 1, a plurality of air distribution holes 11 are uniformly formed in the air distribution disc 1, an extension pipe 12 is fixed at the edge of each air distribution hole 11, the extension pipe 12 protrudes out of the surface of the air distribution disc 1, and the diameter of each air distribution hole 11 is gradually increased from the center of the air distribution disc 1 to the edge of the air distribution disc 1.

Because the adoption sprays the moisture in the circulating water in order to increase the waste gas in the top of gas distribution device among the preliminary treatment process, be suitable for the gas distribution dish 1 at tower equipment, install in the bottom of tower, gas distribution hole 11 sets up upwards, extension pipe 12 can reduce the circulating water that falls on gas distribution dish 1 surface and flow into the probability in gas distribution dish 1, because the diameter of gas distribution hole 11 increases in proper order towards the outer edge from the center of gas distribution dish 1, the diameter of gas distribution hole 11 near the center is little, the gas output is also relatively less, more gas can be followed the border escape of gas distribution dish 1, thereby the gas distribution is even.

The bottom of gas distribution dish 1 is provided with discharge port 16, discharge port 16 slides and is connected with end plug 15, end plug 15 is last to be provided with elastic stand, end plug 15 and gas distribution dish 1 are connected to the stand, and great liquid can be stayed in gas distribution dish 1 from gas distribution hole 11, and when the accumulation volume is more, probably influence the gas distribution effect, when the circulating water volume of discharge port 16 accumulation increases, the stand shrink, end plug 15 receives under the comprehensive force effect of gas and circulating water, gets rid of unnecessary circulating water.

The bottom wall of the air distribution disc 1 is conical, the discharge port 16 is positioned in the center of the bottom wall of the air distribution disc 1, and the bottom wall of the conical air distribution disc 1 can quickly collect liquid and discharge the liquid more quickly.

In order to reduce the circulating water flowing into the air distribution disc 1 from the air distribution holes 11, a conical baffle top 13 is arranged on the extension pipe 12, a return spring 14 is arranged between the baffle top 13 and the extension pipe 12, the return spring 14 extends and retracts along the axial direction of the extension pipe 12, and the baffle top 13 is mainly used for blocking the circulating water from entering the air distribution holes 11.

Keep off top 13 and be provided with dredging rod 17 towards one side of extension pipe 12, dredging rod 17 is concentric in extension pipe 12, under the effect of reset spring 14, circulating water, keeps off top 13 and rocks from top to bottom to drive dredging rod 17 and move from top to bottom, can reduce the probability that the impurity in the circulating water blockked up gas distribution hole 11.

Referring to fig. 3, the cross section of the bottom plug 15 is T-shaped, a plurality of elastic sealing rings 18 are arranged on the side of the large end of the bottom plug 15 facing the discharge port 16, the sealing rings 18 protrude out of the surface of the bottom plug 15, and when the sealing rings 18 are subjected to pressure generated when the stand column contracts, the sealing rings 18 seal the bottom plug 15 and the discharge port 16, so that the escape of gas is reduced, and meanwhile, the plurality of sealing rings 18 can prolong the path of the escape of gas, so that the sealing effect is enhanced.

The implementation principle of the gas distribution device of the biological purification device in the embodiment of the application is as follows: waste gas gets into gas distribution dish 1 from the inlet tank, and waste gas outwards discharges from gas distribution hole 11, keeps off top 13, extension pipe 12 blocks the circulating water and gets into the gas distribution pipe, and when the circulating water volume of spraying was too big, keep off top 13 and reciprocate, and the circulating water probably gets into gas distribution dish 1 from extension pipe 12, accumulates the gravity of too much circulating water, the pressure of waste gas will drive bottom plug 15 and move down, and the circulating water flows from discharge port 16, and the back of flowing out, bottom plug 15 blocks up discharge port 16 in the effect of stand.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
