The original water spraying device and the original spray head are modified, so that the bubble reducing water can be uniformly sprayed on the foam, the spraying area is large, the water consumption is low, the cost is low, the bubble reducing effect is good, and no pollution accident occurs.
Description
Technical Field
The utility model relates to the field of phenol-cyanogen wastewater treatment of coking biochemical stations, in particular to an improved phenol-cyanogen wastewater aeration tank foam reducing device.
Background
The coking biochemical station is used for treating phenolic cyanide wastewater generated in the coking process, wherein the key device is provided with an anaerobic tank and an aeration tank, the anaerobic tank is used for treating ammonia nitrogen in the wastewater, and the aeration tank is used for treating COD in the wastewater. A large amount of bubbles can be generated in the reaction process of biochemical bacteria and COD, and particularly, when the COD content is high, the reaction is more intense and the bubble amount is larger. Some black impurities and greasy dirt are mixed in the bubbles, and if the bubbles are not watered to reduce bubbles, the bubbles overflow the aeration tank, so that the environment is polluted.
In the existing method, water pipes for pumping water and reducing foam are additionally arranged around an aeration tank, and a direct-current spray head is arranged above the water pipes. But the outstanding problem is that the water quantity is too concentrated, no atomization exists, only at the side of the tank, the water quantity consumption is large, the cost is high, the effect is poor, the foam in the tank and the center of the tank is still much, and the foam can overflow the tank to pollute the environment, and the additional problem is that the water treatment capacity of the biochemical station is increased, and the load is increased.
Disclosure of Invention
The utility model aims to provide an improved foam reducing device for a phenol-cyanogen wastewater aeration tank, which is used for improving an original water stirring device and a spray head, so that foam reducing water can be uniformly sprayed on foam, and the foam reducing device has the advantages of large spraying area, low water consumption, low cost, good foam reducing effect and no pollution accident.
The purpose of the utility model is realized in the following way: the utility model provides an improved phenol cyanogen waste water aeration tank bubble reducing device, includes the aeration tank, and a plurality of spraying bridge frames are transversely arranged at the top of aeration tank, and three shower nozzles are installed respectively under every spraying bridge frame bottom surface, and the shower nozzle is 3.5mm apart from liquid level height, and the bridge frame interval is 6cm, and every shower nozzle bottom all is provided with the circular cone diffusion section of thick bamboo, and the even interval is provided with a plurality of atomizing orifices on the bottom surface of circular cone diffusion section of thick bamboo.
The water spraying mode is changed from a side-inclined water spraying and bubble reducing water pipe into a top spraying type spraying and bubble reducing mode, and the spray head is changed from direct-current single-hole water outlet to a jet atomization spray head, so that the spray area can be maximized, the bubble reducing effect is optimal, and the water consumption is low. The spraying amount is regulated by the main valve and the sub-valve according to the foam amount. The device is used on site, the water consumption is obviously reduced, the consumption of defoaming new water is reduced from 45 cubic meters per day to 20 cubic meters per day, the biochemical water treatment cost is reduced, the foam quantity is obviously reduced, no environmental accident occurs, the water flow is uniformly sprayed, the water flow spraying disorder phenomenon is avoided, and the channel guard rail is free from icing in winter.

fig. 2 is a schematic structural view of the spray head of the present utility model.
Description of the embodiments
The utility model provides an improved phenol cyanogen waste water aeration tank bubble reducing device, as shown in fig. 1, 2, including the aeration tank 2 that is provided with inlet tube 3, the top of aeration tank 2 transversely is provided with a plurality of spraying crane span structure 1 at the interval, installs three shower nozzle 3 respectively under every spraying crane span structure 1 bottom surface, and shower nozzle 3 is 3.5mm apart from liquid level height, and crane span structure 1 interval is 6cm, and every shower nozzle 3 bottom all is provided with conical diffusion section of thick bamboo 5, and the even interval is provided with a plurality of atomizing orifices on the bottom surface of conical diffusion section of thick bamboo 5.
Examples
The side inclined water-beating and bubble-reducing water pipe is modified into a top-spraying spray nozzle. The original water-taking pipeline is removed and transformed, the peripheral type bubble-lowering pipe is cut off, and the bridge type top spraying device is modified. Through calculation, the distance between the bridge frames is set to be 6m, two sides of the bridge frames are welded on the guardrail escalator, three spray heads are arranged on each bridge frame, and the distance between the spray heads and the liquid level is 3.5m;
the direct-current spray nozzle is modified into a jet atomization spray nozzle. The original direct-current spray heads are transformed into jet atomizing spray heads with nozzles, and 20 spray heads originally arranged on two sides of an aeration tank are transformed into 12 jet atomizing spray heads sprayed on the top of a bridge frame.
