Description

A kind of sludge agitator tank

Technical field

The present invention relates to a kind of environmental protection equipment, specifically is a kind of sludge agitator tank, and it is visual plant in the dewatering technology of mud, and effect is that oil, oil-containing, sewage containing methanol mud that gas field development produced are stirred, for the operation of back creates conditions.

Background technology

At present, at oil, oil-containing that gas field development produced, contain in the pure sewage of low concentration mud, also there is not equipment from sludge water, mud to be separated.Be originally that the oil-containing that produces, sewage containing methanol mud are moved sludge sump to car in oil recovery, gas and oily(waste)water concentration technology, sewage mud in the sludge sump is by sun natural drying, water, methyl alcohol and condensate oil in the evaporation mud behind the evaporation airing, are transported mud the postpone burning or are buried ground with car again.This processing mode is contaminate environment not only, and processing efficiency is low, and methyl alcohol and condensate oil can not be recycled.

For this reason, the applicant has proposed a kind of novel method for sludge treatment, at first sewage mud is added coagulating agent and mix stirring, make medicament and sewage mud obtain the thorough mixing reaction, enter afterwards in the reactor and react with organic floculant, by forcing machine sewage mud is carried out solid-liquid separation at last, the solid outward transport is handled or is burned, and the oil of separating, water, methyl alcohol etc. enter oily water separation and extraction system is extracted.Wherein sewage mud adding coagulating agent being mixed stirring is committed step of present method, require the dosing of mixed sewage mud even, on the basis that meets the demands, must try one's best to reduce and add dose to save cost, simultaneously owing to solids in the sewage mud is more, and liquid state is constantly evaporated, must guarantee that the sewage mud after the dosing does not harden, can not meet the demands so tie enough stirrers usually.

Summary of the invention

Technical problem to be solved by this invention provides a kind of dosing and sewage mud of making and mixes, and the sewage mud after the dosing does not produce the sludge agitator tank that hardens.

A kind of sludge agitator tank of the present invention, it comprises tank body, central reactor, oil collecting ring, electric motor, stirring rake, described electric motor mounting is at the tank body top, the output shaft of electric motor extends to the tank body inner bottom part always, the coaxial central reactor that installs and fixes formula in tank body, the mouth of pipe of sludge carrier pipe is the oblique insertion central reactor of level top, the oil collecting ring of hollow be located at the central reactor top and with the central reactor internal communication, oil collecting ring is connected to oil header with the light oil output tank body of collecting; Stirring rake is installed in the motor output shaft bottom.

As improvement of the present invention, central reactor is the stepped circular cone bench-type of thin-walled hollow at last, by some vertical grids water eliminator is installed in the central reactor bottom.

As a further improvement on the present invention, stirring rake is preferably cross V-type stirring rake.

Beneficial effect of the present invention:

1, it is simple in structure, easy and simple to handle, and volume is little, automatic degree height, and maintenance workload is few, convenient management, energy consumption is low, and running cost is few.

2, the design by spout, make sewage mud horizontal plane with the off-centered oblique reaction chamber that sprays in the central reactor in, water inlet adds coagulating agent by chemicals dosing plant simultaneously, make medicament and water inlet obtain thorough mixing, sewage mud rotates into central reactor from top, in the reaction chamber of central reactor, be the eddy flow state to prolong current through line, guarantee the reaction times.

3, oil slick is drained the oil automatically by oil collecting ring in oil droplet and the water, recycles.

4, cross V-type stirring rake is set, rotating speed 3～5r/min turns on the contrary with the spirrillum water (flow) direction, and it is more even that sewage mud is stirred, and mixes more thorough.

Description of drawings

Fig. 1 is a structure iron of the present invention.

Fig. 2 is that Figure 1A-A is to sectional view.

Embodiment

As Fig. 1, sludge agitator tank mainly is made up of tank body, central reactor 1, oil collecting ring 2, electric motor 3, stirring rake 5, wherein:

Electric motor 3 is installed in the tank body top, its output shaft extends to the tank body inner bottom part, the coaxial formula central reactor 1 that installs and fixes in tank body, this central reactor 1 is the stepped circular cone bench-type of thin-walled hollow, connects water eliminator 8 in the central reactor bottom by some vertical grids 7.The mouth of pipe of sludge carrier pipe is the oblique insertion central reactor of level 1 top, and oil collecting ring 2 is located at the central reactor top and is communicated with the reaction chamber 4 of central reactor inside, and oil collecting ring 2 is connected to oil header with the light oil output sludge agitator tank of collecting; Stirring rake 5 is installed in the motor output shaft bottom, and this stirring rake 5 is a cross V-type stirring rake.Motorized valve 26 is installed on the sludge carrier pipe that is stretched out by tank base.As Fig. 2, cross V-type stirring rake is made up of the blade of, v font four band 30-degree angle degree, rotating speed of agitator is 3～5r/min, it turns to opposite with the spirrillum water (flow) direction, it is more even that sewage mud is stirred, mud is not separated with water, make not sedimentation of mud, for follow-up stable and the quantitative dosing flocculation reaction lays the foundation.

Concentration is squeezed into sludge agitator tank at the lower concentration oily(waste)water mud of 2000mg/L～60000mg/L by first sludge pump 9, design by spout, make sewage mud horizontal plane with the off-centered oblique reaction chamber 4 that sprays in the central reactor 1 in, water inlet begins to add coagulating agent by chemicals dosing plant simultaneously, make medicament and water inlet obtain filling a part hybrid reaction, sewage mud rotates into central reactor 1 from top, in the reaction chamber 4 of central reactor 1, be the eddy flow state to prolong current through line, guarantee the reaction times, the little oil droplet of dispersive passes through breakdown of emulsion in the water, contact-impact becomes big oil droplet, under buoyancy and sluicing, particle diameter become big oil droplet and water in oil slick be easy to be floated to the import top and form oil reservoir, the most oil slick that is gathered in the central reactor top is drained the oil automatically by oil collecting ring 2.The current spirrillum enters the negative area, bottom, fall and flow in the tank body again on grade water plate 8, directly do not wash away the mud of sludge agitator tank bottom by shelves water plate 8, solidliquid mixture in the equipment is laminar flow regime, be beneficial to the settlement separate of silt particle, in order not make sludge settling solid, the present invention is provided with cross V-type stirring rake, rotating speed 3～5r/min turns on the contrary with the spirrillum water (flow) direction, and it is more even that sewage mud is stirred, mix more thorough, treat to open motorized valve 6 automatically behind the even 10～15min of sludge water stirrer, open second sludge pump 10 of sludge agitator tank bottom in the time of opening of valves, the sewage mud that stirs is discharged.
