Abstract
The utility model discloses an air lift type underwater aeration device based on a high pressure air pump system, which solves the technical problems that the sewage aeration device in the prior art is complex in structure, difficult to maintain and easy to damage. The technical scheme is as follows: the aeration device comprises an open-type aeration barrel vertically located on the bottom of the sewage pool through a support, wherein an air inflation pipeline communicated with a high pressure air pump system is arranged on the bottom of the aeration barrel, and a cyclone cutting type sewage cavitation mechanism is additionally arranged above a gas outlet of the air inflation pipeline and located on the inner wall of the aeration barrel. The air lift type underwater aeration device based on the high pressure air pump system has the beneficial effects that sewage ascends with high pressure gas by using an air-in-water principle, is subjected to cyclone guide segmentation to generate multiple layers of cyclone flows and impact an atomizing segmentation column, so that air and liquid are subjected to cavitation to form a fine tornado, air is forcedly dissolved in water, a water body in a pool forms an up-down circulating state, thus generation and accumulation of sludge on the bottom of the pool are greatly reduced; and the air lift type underwater aeration device is a creative innovation of the traditional aerobic aeration device.
Description
Technical field
The utility model relates to a kind of underwater aeration device, belongs to sewage treatment area, particularly a kind of gas stripping type underwater aeration device based on the high-pressure pump system.
Background technology
At present, the Environmental Protection in China industry development makes rapid progress, and particularly the environmental protection equipment development of manufacturing is rapid.Some occur and had world-class novel process and new installation.For the development of the environmental protection industry (epi) of China provides power.But China's starting is late, and scientific research drops into low, and a lot of basic equipment levels far can not adapt to the requirement of environmental protection situation.Especially the aerobic molten gas aerator of sewage treatment industry, efficient is low, energy consumption is high, fragile, the repair and maintenance expense is big.In the prior art, the aeration of sewage lagoon is handled the general mode that stirs that adopts, and discloses a kind of Aeration stirrer like CN1257849C; Though its agitating vane can arrive at the bottom of the sewage lagoon, and the sewage at the bottom of the sewage lagoon is drawn onto near water surface place, the method that its solution avoids sewage to produce anaerobe remains stirring sewage; Only be to avoid producing " stagnant water " at the bottom of the sewage lagoon; Sewage is contacted with air fully, still can't avoid to produce mud at the bottom of the pond, thereby produce anaerobe; And its device structure is complicated, and safeguards relatively difficulty.Therefore, develop a kind of efficient, low consumption, aerating apparatus easy to maintenance again is very necessary.
Summary of the invention
The utility model is for solving sewage aeration apparatus complex structure in the prior art, being difficult to safeguard and flimsy technical problem; Designed a kind of gas stripping type underwater aeration device based on the high-pressure pump system; Adopt gas stripping type eddy flow cutting aerating apparatus; Reduce design and production cost, be convenient to the maintenance and the maintenance of equipment.
The utility model for realizing the technical scheme that the foregoing invention purpose adopts is; A kind of gas stripping type underwater aeration device based on the high-pressure pump system; Comprise in the structure of above-mentioned aerating apparatus by support and vertically be positioned at the opened type aeration cylinder at the bottom of the sewage lagoon; The aeration cylinder bottom is provided with the gas ducting with the high-pressure pump system connectivity, and is setting up eddy flow cutting type sewage cavitation mechanism above the air outlet of gas ducting and be positioned on the aeration cylinder inwall.
The beneficial effect of the utility model is: the utility model is based on and utilizes band of gas water principle, when sewage is together risen along with high pressure gas, cuts apart through the eddy flow guiding; Produce the multilayer cycle and flow, also clash into atomizing cutting post; Making the gas-liquid cavitation is thin type wind spout shape, air is dissolved in the water by force, and makes the pool inner water body form recurrent state up and down; A large amount of generation and accumulations that reduce pool bottom sludge are the creativeness innovations to traditional aerobic aeration device; Simultaneously, its equipment making is with low cost, safeguards simple.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1 represents aeration cylinder, and 2 represent the water conservancy diversion blade, and 3 represent catch, 3-1 representative atomizing cutting post, and 4 represent gas ducting, and 5 represent support.
Embodiment
A kind of gas stripping type underwater aeration device based on the high-pressure pump system; Comprise in the structure of above-mentioned aerating apparatus by support 5 and vertically be positioned at the opened type aeration cylinder 1 at the bottom of the sewage lagoon; Aeration cylinder 1 bottom is provided with the gas ducting 4 with the high-pressure pump system connectivity, and is setting up eddy flow cutting type sewage cavitation mechanism above the air outlet of gas ducting 4 and be positioned on aeration cylinder 1 inwall.
Comprise in the above-mentioned eddy flow cutting type sewage cavitation mechanism that horizontal symmetrical is arranged on water conservancy diversion blade 2 and the washer 3 that the bottom surface that is arranged on water conservancy diversion blade 2 tops is distributed with convex type atomizing cutting post 3-1 of the air outlet top of gas ducting 4, above water conservancy diversion blade 2 and washer 3 all are positioned on aeration cylinder 1 inwall.
Water conservancy diversion blade 2 in the above-mentioned eddy flow cutting type sewage cavitation mechanism and washer 3 are respectively provided to few four groups and along the cross layered setting of aeration cylinder 1 inwall.
Above-mentioned water conservancy diversion blade 2 adopts screw-blade.
The shape of the atomizing cutting post 3-1 that distributes on the above-mentioned washer 3 is a kind of in hemispherical, cylindric, the taper.
The principle of design of the utility model is: this device is to utilize gas to put forward principle: in aeration cylinder 1, high-pressure air upwards sprays through gas ducting 4, forms siphon power, and water at the bottom of the pond and mud are picked up, and makes its rapid rising.Aeration cylinder 1 top is equipped with water conservancy diversion blade 2 and is had the catch 3 of atomizing cutting post 3-1; Water conservancy diversion blade 2 is used for gas, water water conservancy diversion are formed the wind spout shape; The eddy flow of the band of gas water of wind spout shape hits catch 3 at a high speed; Atomizing cutting post 3-1 on the catch 3 cuts eddy flow, and bubble is disperseed and step-down fast, produces cavitation phenomenon thus.So repeatedly, repeatedly water conservancy diversion, cutting bump repeatedly are dissolved in the water airborne oxygen is enforceable.Owing to suck up the water at the bottom of the pond, mud; Make in the pond to produce cycling stream and secondary dissolved oxygen, prevented the generation and the accumulation of anaerobic sludge at the bottom of the pond, preferably resolve the low deposition with pool bottom sludge of dissolved oxygen efficiency; Dissolved oxygen reaches more than 19%, is more than a times of present aerated product.This apparatus structure is simple, and is sturdy and durable, not fragile, maintenance free, and the life-span can be improved 5～10 times.
The utility model, the constructional feature of its firm and durable is that other products is incomparable.Entire structure is not fragile, need not maintenance basically, and material can be fabricated to products such as stainless steel, general steel, ABS, PVC according to sewage character and customer need.The innovative point of the utility model be overcome other aerated product dissolved oxygen efficiency low, hold to damage, the difficult maintenance, greatly reduce cost of sewage disposal, be novelty innovation to traditional dissolved oxygen aerated product.
