Description

A kind of box dissolved gas floatator
Technical field
This utility model is related to a kind of sewage disposal device, more particularly to a kind of box dissolved gas floatator.
Background technology
Developing rapidly with social economy, the mankind are also increasingly serious for the destruction of environment, for this reason, sewage disposal device Just arise at the historic moment, dissolved gas floatator, as one kind of sewage disposal device, also plays very important effect.In water process neck Domain, air floatation machine is widely used in following several respects: fine suspension, algae and the micro- aggressiveness separating in the surface water;Reclaim industry Paper pulp in useful material in waste water, such as paper waste and filler etc., replace secondary sedimentation tank to separate and concentrate remaining dirty Mud.It is particularly well-suited to those to be easy in the biochemical processing process produce sludge bulking, the suspended oil in separation and recovery oily waste water And oil emulsion, the material of separation and recovery or ionic condition, such as surfactant and metal ion.Dissolved gas floatator operation principle It is under certain condition, the gas-liquid mixed water using gas-liquid mixing pump is soluble in water by large quantity of air, form dissolved air water, as work Make medium, by release sudden pressure reduction, quick release, produce a large amount of microcelles stickups and invest in waste water after coagulating " alumen ustum " on, make flocs float, struck off with Slag Scraping Device simultaneously, thus promptly remove pollutant in water, reach water purification Purpose.The dissolved gas floatator gas-liquid dissolved efficiency being used now is low, and system complex is difficult realization and automatically controls.
Utility model content
Problem to be solved in the utility model is for problem above, provide that a kind of gas-liquid dissolved efficiency is high, structure is simple, It is easy to the box dissolved gas floatator automatically controlling.
For solving the above problems, this utility model be the technical scheme is that a kind of box dissolved gas floatator, including case Body, is provided with gas-floating chamber in described casing, the side of described gas-floating chamber is provided with clear water lifting room, the opposite side of described gas-floating chamber It is provided with molten gas mixing chamber and water medicine mixing chamber, described molten gas mixing interior is provided with release, described clear water lifts the outer of room Upper lateral part is provided with clean water chamber, and the inside upper part that described clear water lifts room is provided with dreg chamber, and the top of described casing is provided with Slag Scraping Device, also includes gas-liquid mixing pump and equalization chamber, and described equalization chamber is passed through pipeline and connected with release and gas-liquid mixing pump respectively Connect, described gas-liquid mixing pump is connected with clean water chamber by pipeline.
Gas-liquid mixing pump air-breathing in water suction, in pump, pressurization mixing, gas-liquid dissolved efficiency height, fine gas bubbles≤30um, molten Air water dissolved efficiency 80-100%, 3 times of traditional air-dissolving air-float efficiency high of ratio, microbubble and the efficient absorption of particle, improve Removal effect, gas-liquid mixing pump may replace circulating pump, air compressor machine, dissolving, ejector and the complicated system discharging first-class composition System, makes structure simpler, low pressure operation, and molten gas efficiency is up to 99%, and release rate is up to 99%, and pressure volume curve is flat, Easily realize automatically controlling, easy care easy to operate, noise are low.
As a kind of prioritization scheme, the bottom that described clear water lifts room is connected with gas-floating chamber.
As a kind of prioritization scheme, the top of described molten gas mixing chamber is connected with gas-floating chamber.
As a kind of prioritization scheme, described release is located at the bottom of molten gas mixing chamber.
As a kind of prioritization scheme, the top that described clear water lifts room is connected with clean water chamber.
This utility model takes above technical scheme, has the advantage that
This box dissolved gas floatator structure is simple, and gas-liquid dissolved efficiency is high, and low pressure operation operates steadily, noise low it is easy to Automatically control it is easy to safeguard.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Brief description
Accompanying drawing 1 is a kind of structural representation of box dissolved gas floatator in this utility model embodiment.
In figure
1- casing;2- clean water chamber;3- clear water lifts room;4- dreg chamber;5- Slag Scraping Device;6- molten gas mixing chamber;7- water medicine mixes Close room;8- release;9- gas-floating chamber;10- equalization chamber;11- gas-liquid mixing pump.
Specific embodiment
Embodiment: as shown in Figure 1, a kind of box dissolved gas floatator, including casing 1, in described casing 1, it is provided with air supporting Room 9, the side of described gas-floating chamber 9 is provided with clear water lifting room 3, and the opposite side of described gas-floating chamber 9 is provided with molten gas mixing chamber 6 He Water medicine mixing chamber 7, is provided with release 8 in described molten gas mixing chamber 6, the outer upper that described clear water lifts room 3 is provided with clearly Hydroecium 2, the inside upper part that described clear water lifts room 3 is provided with dreg chamber 4, and the top of described casing 1 is provided with Slag Scraping Device 5, also Including gas-liquid mixing pump 11 and equalization chamber 10, described equalization chamber 10 is passed through pipeline and is connected with release 8 and gas-liquid mixing pump 11 respectively Connect, described gas-liquid mixing pump 11 is connected with clean water chamber 2 by pipeline.
The bottom that described clear water lifts room 3 is connected with gas-floating chamber 9, and the top of described molten gas mixing chamber 6 is with gas-floating chamber 9 even Logical, the top that described clear water lifts room 3 is connected with clean water chamber 2.
