Description

Decanter Centrifuge for Sludge Dewatering

The invention relates to a decanter centrifuge for carrying out an extraction method. Particularly ,This invention relates to the mechanic engineering field. This utility model relates to the technical field of solid waste treatment method, in particular to a device for advanced treatment of industrial wastewater ; in particular ,it relates to a deep water treatment process and a device for recycling sewage as water resources for reproduction or life in order to achieve a certain reuse water standard after the industrial wastewater is subjected to primary and secondary treatment.

Solid waste refers to a solid or semi-solid waste that is produced by human beings during production and construction, daily life and other activities and cannot be used at certain times and places and is discarded, which pollutes the environment. Oily sludge is a common solid waste in the petrochemical industry, and has characteristics of high oil content, large viscosity, etc., which is difficult to process. The oily sludge contains many petroleum substances, and directly discharging the oily sludge may cause resource waste, and if the treatment is improper, soil and groundwater sources may be polluted, which causes salinization and poisoning, damages and destroys the soil, and toxic materials of the oily sludge may enter food chain system through crops, particularly underground water, and finally directly harms human beings.

According to the CN patent numbered 111609405,     ​The organic solid waste refers to solid organic objects and substances which lose the original utilization value or are discarded or abandoned in production, life and other activities, and mainly comprise domestic garbage, industrial solid waste, agriculture and forestry solid waste and the like. With the development of social economy, a large amount of organic solid waste increases, so that the treatment is more and more difficult, and the problems such as environmental pollution and the like gradually cause wide attention of various boundaries of the society. At present, organic solid waste is generally treated by a composting fermentation treatment mode, and the main defects of the composting disposal mode are that the resource utilization degree is low, the occupied area is large, the climate influence is large, secondary pollution is not easy to control, the automation degree is low, the construction cost and the operation cost are high, and the like, and the problems influence the reasonable disposal of organic solid waste resources.. The gasification technology is a reduction, harmless and resource treatment technology for realizing organic solid waste, and the gasification technology can be combined with combustion and fusion to treat organic solid waste with different characteristics and outstanding social benefits. In recent years, the production amount of industrial wastewater in China is increased year by year, the environment-friendly situation is increasingly severe, and the national improvement of the index requirement of external drainage is met.

According to the CN patent numbered 208717071 Due to the diversity of industrial production, the waste water components generated by the method tend to be relatively complex, the organic matters and the salt content in most industrial wastewater are high, and the standard for recycling and utilizing is difficult to achieve by adopting a conventional method.. Currently, a common wastewater advanced treatment method comprises a biodegradation method, a deep oxidation method, an electrolytic treatment method, activated carbon adsorption, membrane separation, an evaporation concentration method and some combination of a plurality of treatment technologies. In view of the aspects of the occupied area of the equipment, the simple degree of operation, the treatment effect and the like, the evaporation and concentration method is favored by the vast chemical industry and environment-friendly enterprises. The evaporation concentration treatment method tends to be the last process of wastewater advanced treatment, realizes the separation of salt in the wastewater, and realizes the standard discharge of the distilled water.. However, for some difficult-to-treat and evaporation and concentration of wastewater containing special harmful substances, a large amount of foam tends to cause evaporation and concentration to be smoothly carried out. The utility model discloses an evaporation concentration technique is mainly, and a plurality of other technologies provide a device for industrial wastewater advanced treatment, can effectively solve this problem, and realize the zero emission of waste water.

This invention relates to a utility model which separates solid harmful particles from water surfaces to treat factories wastes .In this device a filter is applied to separate solid particles from waste water before entering to the sea ,beside that, a chemical filter is devised to suction all the unwanted particles in the output of waste passages ,this apparatus can be applied both portable or installable.

Water leakage is not the only common water purifier problem that is faced by people. There are various other issues that can arise after a few years of water purifier usage, including unusual taste, unusual smell, noisy faucet, and slow water output. the most common problem encountered by residential water filtration systems is a dirty filter. This lets chemicals and heavy metals to find the way into drinking water. There are different types of water filtering systems, each of which has its own requirements for maintaining the filter.

In the prior arts, most oily sludge is treated in an open-air stacking or landfill manner, if the sludge directly contacts the natural environment, large pollution to the soil, water, and vegetation is caused and waste of petroleum resources is also caused. Therefore, there is an urgent need to provide an effective, non-polluting solid waste treatment method for oily sludge in the petrochemical industry .To solve the mentioned problems ,this utility model is invented which aims to overcome the defects in the prior art, and provides a device for deep treatment of industrial wastewater. The device is high in wastewater advanced treatment efficiency, easy to operate, low in investment cost, small in occupied area and suitable for large-batch continuous treatment .The purpose of this utility model is to provide a kind of centrifuge suction system which can effectively suck away the harmful materials. In the current invention ,a decanter centrifuge is presented to isolate solid particles from surface of water.

In this invention, centrifugal force has applied to separate suspended solid particles in the waste water .This force is about 30000 times more than the gravity force , which results in perfect purification of waste water.

The present invention is best understood by the description set forth herein .To achieve the foregoing and in accordance with the purpose of the invention , and to overcome the problems and shortcomings associated with the prior art ,the most preferred embodiments are described here.

A Decanter centrifuge comprises a complex mechanism ,but its structure is based on some principal basics to transfer materials with screws. Its configuration consists an internal cylindrical space(bowl)which rotates in up direction at different rates. This decanter centrifuge mostly moves in the horizontal direction to filter the unwanted materials perfectly.

Two dynamos (fig.1) are devised in this system to produce power and generate the main screw and other embodiments connected to the body of the centrifuge (fig.2).The body is installed on the main chassis.
