Brief and applications:
In the water supply and drainage treatment process procedures, the solid and liquid separation technology and equipment is one of the key projects. For the removal of water close to the proportion of small suspended particles, air is one of the most effective methods. The device is widely used for wastewater treatment works.
First, water is applied to the lake water for the water treatment plants, algae Jiangzhuo.
The second, used in industrial sewage treatment works, such as petrochemical, textile, printing and dyeing, electroplating, food industry and other fields.
Third, used in sewage recycling useful materials. Such as: paper, pulp fiber in water recycling and other fields.
Industry principle:
Flotation separation technology is the air and water at a certain pressure, the gas dissolved in water greatly limit, and strive to be saturated, and the pressure of dissolved gas and water formed by the release of pressure, a large amount of fine bubbles full contact with the suspended floc in the water, so that the water suspended floc adhesion of the micro-bubbles, together with bubble float to the surface, forming scum and scrape off the scum, so quality water purification.
QF type High efficient shallow pool flotation device developed by us, it is an advanced rapid flotation system, based on the traditional flotation theory, and the successful use of the "shallow pool theory" and "zero speed" principle, by designed collection cohesion, flotation, skimming, precipitation, scraping mud as a whole, is a water purification process of the High efficient equipment.
QF-type flotation device compared with conventional flotation device, the main differences are as follows: conventional flotation device, water, water are fixed, the separation process is dynamic. Its biggest drawback is that separating the reaction is carried out in an unstable state under water, and the mutual interference, separate the dross rises caused an extremely negative impact. In order to achieve a good separation, must give rise scum of sufficient time, HRT is usually 20-50MIN, some even up to as much as one hour, resulting in the pond volume increases.
I plant on its own design and development of QF type High efficient shallow pool flotation device inadequacies of traditional flotation devices, the raw water inlet, water purification outlet designed to mobile, static separation process to shorten the source edema bubbles float time , pond water flow pattern basically relatively stationary. Raw water suspended solids float to the surface from the bottom of the speed (up to 40-100MM / MIN), depth of just 400-500MM on it, that the residence time of 3-5 minutes, to purify the raw water requirements. In order to import and export energy synchronous rotation, the machine is designed to circle.
Main technical characteristics:
1. Effective water depth 400-500MM
2. pool short hydraulic retention time (3-5MIN)
3. purification capacity, namely high surface load.
4. small footprint, the unit load is light, all prefabricated assembly, no operating room, equipment can be installed overhead, can also be a multi-layer combinations.
5. Install low maintenance costs, easy to clean.
6. High degree of purification, suspended solids in addition to more than 90%.
7. The device structure ingenious, dissolved air efficiency up to 90%, only one-fifth the volume of dissolved air systems in general.
The main structure:
1.QF Type High efficient shallow layer gas floating device set agglomeration, flotation, skimming, precipitation, scraping mud as a whole, overall cylindrical, compact, shallow pond. Apparatus body consists of five major components: the cell body, rotating water bodies, dissolved air release mechanism, institutional framework, catchment agencies. Inlet, outlet and exhaust port scum all concentrated in the central region of the cell body, water distribution agencies, watershed organizations, dissolved air release mechanism are closely connected with the production together, rotating around the center of the cell body.
2. This device provides equipment assembly and control system, through centralized control and decentralized control combined to make equipment for optimum operation. |
