Description
Technical field
The utility model belongs to technical field of sewage, relates to a kind of airtight employing negative pressure self-priming aeration, has the waste disposal plant of liquid automatic control simultaneously.
Background technology
In sewage treatment project application, conventional method is the method that combines of physical method, chemical process and physical chemistry mainly, and aeration is the core technology of physical method and chemical process.Such as: the method oil removing adopting physics, needs to carry out aeration stripping; Adopt oxidizing sulfur dioxide method to need to pass into air, sulfurous gas just can be made to play chemical reaction effect, so aeration is engineer applied common technology.But engineering of water treatment application is normal uses independent source of the gas air supply, as blower fan etc., it is longer to there is pipeline in independent source of the gas supply, and investment is comparatively large, runs and maintenance cost is higher and mix the problems such as uneven.In addition, in sewage treatment project application, main body reaction unit fluid often needs manual control, and level of automation is lower.A kind of negative pressure aeration automatically controls reaction unit and is exactly shortcoming for device in above-mentioned sewage treatment process and designs and develops.
Summary of the invention
The purpose of this utility model is exactly to solve the problem, and provides a kind of negative pressure aeration automatically to control reaction unit.The pipeline that the utility model effectively can to solve in sewage disposal supply source of the gas separately and exist is longer, and investment is comparatively large, runs and maintenance cost is higher and mix the problems such as uneven, and can unmanned be realized, equipment is simple, stable, level of automation is higher, practical.
The utility model is made up of be mixed device, cylindrical shell, fluid inlet, anti-fluctuation liquid level protective guard and turbulence plate of motor reducer, negative pressure inlet mouth, air outlet, transmission shaft, sleeve pipe, upper floating ball liquidometer, lower floating ball lever meter, flange, liquid outlet, maintenance evacuation port, bottom bulkhead, negative pressure relieving stagnant Qi, and motor reducer and cylindrical shell pass through Flange joint; Transmission shaft connects motor reducer, and the lower negative pressure relieving stagnant Qi of connecting is mixed device; The outside mounting sleeve of transmission shaft, cannula tip is provided with sealed negative-pressure inlet mouth; Cylinder top sets out gas port, and middle part arranges fluid inlet and upper floating ball liquidometer, lower floating ball lever meter; Cylindrical shell and bottom bulkhead pass through Flange joint; Bottom bulkhead is provided with liquid outlet and maintenance evacuation port; Inner barrel is provided with turbulence plate and anti-wave protection cover, and anti-wave protection cover mainly prevents turbulent flow from affecting liquid level result of use.
Utility model works process:
Sewage enters reaction unit by fluid inlet, and when opening motor reducer, the negative pressure relieving stagnant Qi device that is mixed can make inside pipe casing form negative pressure, and introduced by air, meanwhile, air can be broken into micro-bubble by the negative pressure relieving stagnant Qi device that is mixed, and fully mixes with sewage.When liquid level rises to upper floating ball liquidometer, liquidometer can be opened by automatic control pump, is walked by the sump pump in reaction unit, and when liquid level drops to lower floating ball lever meter, liquidometer can stop fluid by automatic control pump, realizes automatic control function.Gas is discharged through air outlet, if tail gas does not reach emission standard, can cause qualified discharge after absorbing in absorption liquid.
The beneficial effects of the utility model:
Negative pressure aeration controls that reaction unit to solve in sewage disposal supply source of the gas separately automatically and the pipeline that exists is longer, invest larger, run and maintenance cost higher and mix the problems such as uneven, and do not need to supply source of the gas separately, rely on intrinsic advantage negative pressure to introduce gas aeration stripping.This device is confined reaction device, and air outlet can be connected to other tail gas and destroys or in device for absorbing tail gas, ensure tail gas qualified discharge.This device can realize unmanned, and in addition, this device can be used for the removal that ore pulp etc. contains solid particle medium Impurity, and equipment is simple, and level of automation is higher, practical.
