Description
Technical Field
The utility model relates to a municipal administration sewage treatment field.
Background
The sewage is mainly in an anoxic environment in the pipeline conveying process, and researches show that the improvement of the oxygen content of the sewage is beneficial to the growth of aerobic microorganisms in the sewage, so that a better purification effect is achieved. Some sewage oxygenating devices in the prior art have certain defects, such as a pressure tube type sewage treatment reactor, negative pressure oxygenating is formed by pressurizing through a water pump, the structure is complex, the energy consumption of the water pump is large, and the sewage oxygenating device is not suitable for remote environments such as rural areas; in another negative pressure aeration device, the negative pressure aeration device comprises an outer shaft, an inner shaft, an aeration pipe and other structures, the device is complex, is limited to aeration operation in a deep well, and is applicable to a single environment.
Disclosure of Invention
The utility model aims at providing a gravity type negative pressure is from oxygenating pipe-line installation, need not too much energy, and easy operation is convenient, and application scope is extensive.
The technical solution of the utility model is that: the utility model provides a gravity type negative pressure is from oxygenating pipe device, is including inlet tube, electric butterfly valve, spherical pipe and the outlet pipe that is equipped with the vertical section, and wherein electric butterfly valve sets up on the vertical section of inlet tube, and the top intercommunication electric butterfly valve below vertical section, bottom intercommunication outlet pipe of spherical pipe. The diameter of the spherical pipe is larger than that of the vertical section, and at least two air inlet pipes are arranged on the spherical pipe.
The inlet tube is equipped with the vertical section, be equipped with electric butterfly valve on the vertical section, can control the water yield size after the valve, because the diameter of bulb is greater than the diameter of vertical section, consequently when the bulb intakes, can not fill up the space in the bulb completely, upper portion has gas in the bulb, outlet pipe when the bulb bottom is in the play water, can form the negative pressure in the bulb, thereby make external air pass through the intake pipe and get into the interior and intake natural mixing of bulb, make the water oxygen boosting, whole device only electric butterfly valve need consume the electric energy, the overall energy consumption is few, moreover, the steam generator is simple in structure, can be applicable to various environments.
Four air inlet pipes are symmetrically arranged in the middle of the spherical pipe. The uniformity of air inlet is improved, and the hollow part in the middle of the spherical pipe is large, which is more beneficial to the mixing of air and water.
The top end of the air inlet pipe is provided with a rain-proof cap. The spherical pipe is prevented from being completely filled with water due to the fact that rainwater is sucked from the air inlet pipe, and air cannot be introduced due to the fact that negative pressure is reduced.
The diameter of the spherical pipe is 2-4 times of that of the vertical section of the water inlet pipe. Negative pressure can be formed quickly, and the gas-water mixing efficiency is highest.
The utility model has the advantages that: simple structure, little energy consumption, convenient operation and simple and convenient maintenance, and is suitable for various environments.

Detailed Description
Example (b):
referring to fig. 1, a gravity type negative pressure self-oxygenating pipeline device is arranged below a ground 8 and comprises a water inlet pipe 1 provided with a vertical section 2, an electric butterfly valve 3, a spherical pipe 4 and a water outlet pipe 5, wherein the electric butterfly valve 3 is arranged on the vertical section 2 of the water inlet pipe 1, the top end of the spherical pipe 4 is communicated with the vertical section 2 below the electric butterfly valve 3, and the bottom of the spherical pipe is communicated with the water outlet pipe 5. The diameter of the bulb 4 is larger than that of the vertical section 2, and at least two air inlet pipes 6 are arranged on the bulb 4.
Four air inlet pipes 6 are symmetrically arranged in the middle of the spherical pipe 4. Four air inlet pipes 6 are symmetrically arranged on the large circumference of the spherical pipe 4, so that the air inlet uniformity can be improved, and the hollow part in the middle of the spherical pipe 4 is large, so that the air-water mixing is facilitated.
A rain hat 7 is arranged at the top end of the air inlet pipe 6. The spherical pipe is prevented from being completely filled with water due to the fact that rainwater is sucked from the air inlet pipe, and air cannot be introduced due to the fact that negative pressure is reduced.
The diameter of the bulb 4 is 2-4 times the diameter of the vertical section 2 of the inlet pipe 1. Negative pressure can be formed quickly, and the gas-water mixing efficiency is highest. The electric butterfly valve 3 can control the water inflow, and a certain water blocking height is formed in the upstream vertical section 2, so that negative pressure can be quickly formed in the spherical pipe 4.
The above detailed description is specific to one possible embodiment of the present invention, and the embodiment is not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the scope of the present invention should be included within the scope of the present invention.
