Vortex concave air flotation machine product introduction
Series Vortex concave air flotation machine The machine has a removal rate of D and BD of more than % and a removal rate of more than %. It has the advantages of low energy consumption, high efficiency, economical operation, convenient operation, low investment cost, small floor space, etc. It is widely used in papermaking, chemical industry, printing and dyeing Treatment of industrial sewage and urban sewage in , oil refining, starch, food and other industries.
The structure of vortex concave air flotation equipment
The vortex concave air flotation equipment mainly includes air flotation box, vortex concave aerator, chain scraper system, scum collection and discharge system, and overflow drainage system. , electronic control system, dispensing tank, storage tank, glass rotor flowmeter, return pipe, annular operating table, and dosing pump.
The equipment box can be an integral steel plate structure. It is recommended that when the water treatment capacity of a single machine exceeds m/h, the box body should adopt a reinforced concrete structure.
Working principle of vortex concave air flotation equipment
Pollutants in sewage are divided into dissolved organic matter and insoluble matter (i.e.). Dissolved organic matter can be converted into insoluble organic matter under certain conditions. Substances, one of the methods of sewage treatment is to add coagulants and flocculants to convert most of the dissolved organic matter into insoluble substances, and then remove all or most of the insoluble organic matter (i.e.) to achieve the purpose of purifying sewage purpose, and the main method of removal is to use air flotation.
It is the process of generating flotation from air. The vortex aerator injects microbubbles directly into the sewage without dissolving the air in advance, and then evenly distributes the microbubbles in the sewage through the precision-cast stainless steel diffuser impeller, so no clogging will occur. This equipment does not require pressure. Auxiliary equipment such as containers, air compressors and circulation pumps.
The untreated sewage first enters the aeration section and is fully mixed with micro-bubbles. During the rising process, the micro-bubbles bring suspended solids to the water surface. The sludge scraper moves along the liquid surface, scrapes the suspended solids onto the inclined metal plate, and then pushes it into the sludge discharge pipe. There is a horizontal screw propeller in the sludge discharge pipe, which sends the collected sludge to the sludge collector. The propeller and the scraper are driven by the same motor. The purified sewage will pass through the overflow tank under the inclined plate before being discharged. The overflow tank is used to control the water level of the air flotation tank to ensure that the liquid in the tank does not flow into the sludge discharge pipe.
The open return pipe extends from the aeration section along the bottom of the flotation tank. While generating microbubbles, the vortex aerator will form a negative pressure area at the bottom of the pool with a return pipe. This negative pressure will cause the water to flow back from the bottom of the pool to the aeration area, and then return to the air flotation section. The return pipe is equipped with a one-way valve to prevent the sewage entering the aeration tank from directly entering the flotation tank from the return pipe without treatment. The entire process ensures that air flotation continues even when there is no inflow.
Advantages of vortex concave air flotation equipment
Saving investment
It does not require pressure dissolved air tanks, air compressors, circulation pumps and other ancillary equipment to treat urban sewage and industrial sewage. This equipment can remove grease, colloids, suspended solids, D and BD in sewage. Using it to treat chemical pulping mid-stage wastewater can greatly reduce biochemical secondary treatment (if waste paper is used as raw material, deinking, bleaching, etc. The wastewater generated during the process can reach the standard for discharge or reuse without secondary biochemical treatment.) The scale of the equipment can even save the biochemical treatment process and directly reach the standard for discharge, thus greatly reducing the overall investment cost.
, low operating cost
The equipment uses a multi-element aeration head, and the number of aerators is determined according to the different water volumes. Each aerator has only one power. The scraper and sludge screw propeller are driven by the same Driven by a motor, the power is... The entire set of vortex air flotation equipment consumes very little power, which is only equivalent to that of the traditional dissolved air flotation method. Moreover, maintenance and manual operations are minimal, and no workers are required to monitor it during normal operation.
, high efficiency
Contrary to traditional grease collectors (gravity settling tanks and separation tanks), solid sludge is automatically and continuously removed from wastewater. The removal and storage of sludge is carried out in a concentrated manner. The highest concentration of floating sludge collected by this equipment can reach about %, thus reducing the operating costs of sludge treatment.
, superior performance
The processing capacity of the vortex concave air flotation equipment is cubic meters/hour. Equipment with different flow rates should be designed according to customer requirements. The amount of water entering the air flotation machine does not need to be balanced. Even if the flow rate changes, the equipment can work normally. Under normal circumstances, the removal rate of grease and solid floating matter exceeds 50%. Obviously, while grease and suspended solids are being removed, the load on BD is also greatly reduced, and usually the removal rate of D can reach more than %.
, simple operation
The vortex concave air flotation equipment has a simple structure, a high degree of automation, and easy operation and maintenance.
, odor reduction
The treatment of wastewater by the vortex air flotation equipment is an aerobic process, and the sludge is removed in a fresh state, so it is collected by the grease collector (gravity settling tank and separation tank ) has been well solved. On the other hand, it increases the possibility of solid reuse and reduces disposal hassles.
, easy to install
There are very few civil engineering projects to support the vortex air flotation equipment. It can be installed on the ground, underground or at high places, and it takes very little time.
, small footprint
The installation area of the vortex concave air flotation equipment with a processing capacity of cubic meters per hour is only .~ square meters.
