Abstract
The utility model discloses a multi-way jet flow aerator which comprises an ejector and a plurality of jet flow aeration nozzles, wherein the jet flow aeration nozzles are symmetrically arranged in the perimeter direction of the ejector; a flange at one end of the ejector is connected with a water inlet, and a flange at the other end of the ejector is connected with an air inlet. The multi-way jet flow aerator is convenient to assemble and disassemble without production stopping and machine halt; the service area of one jet flow aerator is about 15-20 m<2>, and the service area of a single aerator is large, so that a small number of aerators are needed in an aeration tank, the investment is small, and the operation cost is saved; a high oxygen transfer efficiency is achieved, that is, the oxygen transfer efficiency can be greater than 40% when water is 8 meters deep, so that the multi-way jet flow aerator is applicable to a membrane bioreactor (MBR) system with high concentration of mixed liquor suspended solids (MLSS).
Description
Technical field
The utility model belongs to waste disposal plant technical field, more particularly, is a kind of multichannel jet aerator.
Background technology
Multichannel jet Aeration Technology and Its has been widely used in all kinds of sewage treatment facilities and technique.But the subject matter existing is at present that the quantity of required installation is many because traditional aerator service area is little, and oxygen transfer efficiency is low, and complex structure easily stops up, cause manufacture, installation, maintenance difficulty.For user, the aerator that energy consumption is high, by increasing the expense of its operation and maintenance, increases economical load, affects the normal operation of sewage works.
Utility model content
Due to the problems referred to above that prior art exists, the purpose of this utility model is to propose a kind of multichannel jet device that exposes to the sun, and it is difficult for stopping up, applicable to containing compared with the waste water of the easy fouling of high calcium, magnesium ion; Easy for installation, by the flange of jet aerator upper and lower, connect with compressed-air line and motive fluid pipeline; Easy removal.
For achieving the above object, the utility model can be achieved by the following technical programs:
A kind of multichannel jet of the present utility model device that exposes to the sun, comprises ejector, several jet-flow aeration shower nozzles, and jet-flow aeration shower nozzle is symmetrical arranged in the circumferential direction of ejector, and the flange of ejector one end connects water-in, and the flange of the ejector the other end connects inlet mouth.
Wherein, the power jet of described jet-flow aeration shower nozzle is furnished with anti-clogging plug spiral.
Wherein, the passage of described jet-flow aeration pipe is not less than 1cm.
Owing to adopting above technical scheme, a kind of multichannel jet of the present utility model device that exposes to the sun is self-priming, when work without any mechanical moving element, from bottom, connect motive fluid, from top, connect pressurized air, fluid jet nozzle is sideling at the bottom of pond, and its angle can regulate respectively according to mounting condition; Adopt special PP material, there is high strength, without sticky stifled feature; The passage of jet-flow aeration pipe is not less than 1cm, is difficult for stopping up, applicable to containing compared with the waste water of the easy fouling of high calcium, magnesium ion; Easy for installation, by the flange of jet aerator upper and lower, connect with compressed-air line and motive fluid pipeline; Easy removal, shuts down without stopping production, and the service area of a jet aerator is about 15～20m
2, the service area of single aerator is large, and the required aerator quantity in aeration tank is few, less investment and save operation cost; Efficient oxygen transfer efficiency, during 8 meters of the depth of waters, can reach more than 40%, is applicable to membrane bioreactor (MBR) system that sludge concentration (MLSS) is higher.
Accompanying drawing explanation
The utility model is described in further detail with specific embodiment with reference to the accompanying drawings below:
The side-view of a kind of novel multichannel jet aerator that Fig. 1 provides for the utility model;
The vertical view of a kind of novel multichannel jet aerator that Fig. 2 provides for the utility model.
Embodiment
As shown in Figures 1 and 2, a kind of multichannel jet aerator of the present utility model, comprise ejector 1, jet-flow aeration shower nozzle 2, jet-flow aeration pipe 2 is symmetrical in the circumferential direction of ejector 1, the flange 3 of water-in connection ejector one end is connected the flange 4 of the ejector the other end with inlet mouth, the passage of jet-flow aeration shower nozzle 2 is not less than 1cm, and the power jet of jet-flow aeration shower nozzle 2 is furnished with anti-clogging plug spiral.
But above-mentioned embodiment is exemplary, be to be this patent to be comprised to the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do be anyly equal to change or modify, all fall into the scope that this patent comprises.
Claims (3)
1. the multichannel jet device that exposes to the sun, is characterized in that: comprise ejector, and several jet-flow aeration shower nozzles, jet-flow aeration shower nozzle is symmetrical arranged in the circumferential direction of ejector, and the flange of ejector one end connects water-in, and the flange of the ejector the other end connects inlet mouth.
2. the multichannel jet according to claim 1 device that exposes to the sun, is characterized in that: the power jet of described jet-flow aeration shower nozzle is furnished with anti-clogging plug spiral.
