Abstract

The utility model discloses a jet type deep oxygenation device, belongs to the technical field of water body oxygenation and aims to overcome the defects of low oxygenation efficiency, high primary investment, high energy consumption, high noise and the like of current common oxygenation ways. The jet type deep oxygenation device comprises a pontoon, a centrifugal pump is mounted on the pontoon, a water inlet pipe, a water outlet valve and a water outlet pipe are mounted on the centrifugal pump, an inlet of the water inlet pipe extends into water, and an outlet of the water outlet pipe extends to the deep of a water body. At least one air inlet pipe is arranged on the pipe section, above the water surface, of the water outlet pipe. An air inlet valve is mounted on each air inlet pipe, and a power supply terminal of the centrifugal pump is connected with a power source through a power wire. The jet type deep oxygenation device is applicable to water body oxygenation for projects of sewage treatment, aquaculture, water conservation and the like.

Description

Jet deep layer oxygen-increasing device
Technical field
The utility model relates to a kind of water body bleeding technique, particularly involves in a kind of jet deep layer oxygen-increasing device.
Background technology
In order to increase the dissolved oxygen in the water body and to improve the convection current degree of each layer current in the water body, simultaneously, evenly water quality and the activity that improves water body are in sewage treatment project, in the culture fishery, all will carry out the oxygenation operation to some water body in the hydro project.At present, the oxygenation way that adopts at most is water jet, surface aeration formula and blowing-type.Water jet and surface aeration formula, though it is equipment is simple, easy to use; Initial cost is economized, but the efficient of oxygenation is lower, and the oxygen dissolving all concentrates on the surface and the upper strata of water body and carries out; The solubleness of oxygen is very inhomogeneous on the vertical direction of water body, and in dark slightly aspect, the solubleness of oxygen is almost nil.Though the blowing-type gas distribution pipe is located at the bottom of water body, can solve the water body solubleness problem pockety of oxygen in vertical direction, to the darker engineering of water body, must adopt the higher blower fan of working head, like roots blower.Exist initial cost big, energy consumption is high, also need establish special machine room, the big deficiency that waits of noise during work.In addition, when the oxygenation method of blowing-type, air flow to water body from the cloth gas port; Do not disturbed, be mode with bubble float and the exposure level of water body very insufficient; There is air-flow greatly not dissolve in the water but emerges, cause very big waste with the mode of bubble.
Summary of the invention
The purpose of the utility model provides a kind of jet deep layer oxygen-increasing device, overcomes deficiencies such as at present general oxygenation way exists, and oxygenation efficient is low, initial cost is big, energy consumption is high, noise is big.
The utility model is achieved through following technical proposals.
The utility model comprises pontoon; On said pontoon, impeller pump is housed, water inlet pipe, outlet valve and rising pipe are housed on the said impeller pump, the import of said water inlet pipe is stretched in the water; The water body depths is stretched in the outlet of said rising pipe; Pipeline section more than the said rising pipe water surface is provided with at least one inlet pipe, on the said inlet pipe intake valve is housed, and the power supply terminal of said impeller pump is by supply lead and power connection.In the utility model; The said water inlet pipe water inlet water surface is shorter to the distance at the center of said impeller pump, and pump consumes at the energy of negative pressure suction end very little when work; Its main energy is all brought into play in water outlet malleation end; And, need catabiotic on-way resistance very little because said rising pipe neither be very long, want catabiotic parts also few in the pipeline.Therefore, under the situation of said outlet valve standard-sized sheet, when said impeller pump was worked, the energy of pump was mainly reflected on the kinetic energy of water outlet.That is to say that the current that in said rising pipe, flow through have sufficiently high flow velocity.The dynamic pressure that current produced of this enough high flow rate is then greater than total head, and therefore, the static pressure that on said rising pipe pipeline section, is showed is a negative value, and this just causes said inlet pipe can suck swiftly flowing current mixing in a large amount of air and the pipe.Because the flow rate of water flow in the said rising pipe is very high, is serious turbulent state, the gas that sucks from said inlet pipe can fully contact with current, and oxygen can more fully dissolve in the current; At last, the current that are dissolved with more oxygen are thrown into the depths of water body from the outlet of said rising pipe.
To export effusive current from said rising pipe and can intersperse among better more equably the water body in order to make, in the outlet of said rising pipe sparger is housed, said sparger is a flaring rectangle diffluence pass, and perhaps, said sparger is the circular diffluence pass of flaring.For when starting said impeller pump, the convenience of perfusion diversion is equipped with bottom valve in the import of said water inlet pipe.
Against existing technologies, the beneficial effect of the utility model is:
Under the prerequisite of saving initial cost, low power consuming, reach purpose to the efficient even oxygen aeration of water body deep layer.
Description of drawings
Fig. 1 is the structural representation (said sparger is a flaring rectangle splitter) of the utility model, and Fig. 2 is that the A of Fig. 1 is to view.Among the figure: 1, pontoon, 2, impeller pump, 3, water inlet pipe, 4, outlet valve, 5, rising pipe, 6, inlet pipe, 7, intake valve, 8, supply lead, 9, sparger, 10, bottom valve.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The utility model is when implementing, and need guarantee has sufficiently high flow velocity through the current of rising pipe 5, and the dynamic pressure that makes it is greater than total head, thereby on inlet pipe 6, produces negative pressure.This can calculate through simple, sets about from the aspects such as length of impeller pump 2, turnover Guan Guanjing, pipeline component, pipeline, rationally matches to meet the demands.In the present embodiment, the caliber of water inlet pipe and water outlet pipe selects greatly, select for use 45 ° channel bend etc. all to help producing on the inlet pipe 6 bigger negative pressure; Thereby the air voids in the raising current.Because effusive current are different because of how many density of air content with the water in the water body from sparger 9, so current can further spring up in water body, make more uniformity of the oxygen level of water body on level, vertical two directions.The effect of pontoon 1 can make present embodiment move at the surperficial different positions of water body.
