Abstract
In order to solve the problems of high power, high energy consumption and the like of an air compressor of the conventional deep well aeration device, the invention develops a novel negative pressure aeration device which comprises an outer shaft, an inner shaft and an aeration pipe, wherein the inner shaft is arranged in the outer shaft, the bottom end of the inner shaft is open, the bottom end of the outer shaft is closed, the novel negative pressure aeration device also comprises a negative pressure aeration pipe and an air flow lifting pipe, the air outlet of the negative pressure aeration pipe and the air outlet of the aeration pipe are both arranged in the inner shaft or both arranged in the outer shaft, correspondingly, the air outlet of the air flow lifting pipe is arranged in the outer shaft or the inner shaft, and the air. The invention adds the negative pressure aeration pipe and the airflow lifting pipe on the basis of the existing deep well aeration device, and utilizes the negative pressure generated after the water flow in the aeration well reaches a certain flow velocity to perform self-aeration operation, thereby reducing a large amount of energy consumption generated by the operation of the air compressor, reducing the operation cost of equipment while saving energy, and improving the market competitiveness.
Description
Technical field
The invention belongs to sewage deep well treatment facility technical field, be specifically related to the negative pressure by utilizing deep-well inner high voltage aeration to produce and carry out automatic aeration, thus save a kind of novel negative pressure aerating apparatus of high pressure aeration energy consumption.
Background technology
Sewage deep well treatment technology is introduced China and is studied from the eighties, through the development of nearly decades, applies at municipal effluent and trade effluent field as the industries such as food, chemical industry, printing and dyeing, pharmacy obtain and obtains unusual effect.Deep well aeration is the gordian technique of sewage deep well process, it is by under the well-digging in depth of aeration tank, by high pressure aeration pipe pressurized air inputted in aeration well and carry out aeration, deep well aeration is effective, coefficient of oxygen utilization is high, but because of well depth hundred meters, air pressure required for deep well aeration is far longer than common aeration pressure used, so, prior art middle-deep well aeration requires strict to air compressor machine, need high-power air compressor machine to run continuously for 24 hours, cause very large energy consumption, be unfavorable for saving and the utilization of the energy, and add the cost of sewage disposal of enterprise.
Summary of the invention
For solving the problems such as existing deep well aeration device air compressor machine power is large, energy consumption is high, the present invention have developed a kind of novel negative pressure aerating apparatus, the negative pressure that this device produces after utilizing current in aeration well to reach certain flow rate and voluntarily aeration run, thus decrease air compressor machine and operate a large amount of energy consumptions produced.
For achieving the above object, the technical solution used in the present invention is:
A kind of novel negative pressure aerating apparatus, comprise outer shaft wall, interior pit shaft, aeration tube, interior pit shaft is arranged in outer shaft wall, interior pit shaft bottom end opening, outer shaft wall bottom end closure, it is characterized in that: also comprise negative pressure aeration pipe, described negative pressure aeration pipe air outlet and aeration tube air outlet are arranged in interior pit shaft all simultaneously or are arranged in outer shaft wall all simultaneously.
Also comprise gas lift pipe, described gas lift pipe air outlet upward; Correspondingly, described gas lift pipe air outlet is arranged in outer shaft wall or in interior pit shaft.
Described negative pressure aeration pipe, aeration tube and air-flow riser tube are arranged in outer shaft wall or in interior pit shaft simultaneously.
Described negative pressure aeration pipe top arranges a negative pressure gauge.
Described aeration tube is 1 to 4.
Described negative pressure aeration pipe is 1 to 4.
Compared with prior art, the invention has the beneficial effects as follows: the present invention increases and arranges negative pressure aeration pipe and air-flow riser tube on the basis of existing deep well aeration device, the negative pressure produced after utilizing current in aeration well to reach certain flow rate and voluntarily aeration run, thus decrease air compressor machine and operate a large amount of energy consumptions produced, while save energy, reduce the running cost of equipment, improve the market competitiveness.
