Novel high-concentration emulsified wastewater deemulsification device

Abstract

The invention discloses a novel high-concentration emulsified wastewater deemulsification device, which comprises a deemulsification groove (1) and a microwave generator (2) and is characterized in that the microwave generator (2) is arranged at the bottom of the deemulsification groove (1), the deemulsification groove (1) is provided with a charging pump (3) and is internally provided with a stirring mechanism (4), and the upper part of the deemulsification groove (1) is provided with an oil collecting cavity (5) which is internally provided with a rotary oil suction scraper (6). The novel high-concentration emulsified wastewater deemulsification device provided by the invention integrates the effects of chemical deemulsification and microwave deemulsification, is compact and occupies less flow area; and by means of the synergistic effect of the chemical deemulsification and the microwave deemulsification, the use level of a deemulsifier is decreased and the sludge quantity of oil and water is effectively reduced. The processing technology not only has the advantages of thoroughness in oil-water separation, good treatment effect and stability in long-term operation, but also has high deemulsification efficiency reaching above 90%.

Description

technical field [0001] The invention relates to the field of wastewater treatment facilities and devices, in particular to a novel high-concentration emulsified wastewater treatment device for high-concentration emulsified wastewater treatment in industries such as automobiles and machinery. Background technique [0002] Emulsion is diluted with emulsified oil and water. It is widely used in automobiles, machinery and other industries, and has the functions of cooling, lubricating and cleaning. The emulsion contains a large amount of lubricating oil, surfactants and fatty acid sodium salts. Due to the influence of heat friction, metal dust and surrounding environmental media during recycling, it will gradually deteriorate and lose its effect, and form emulsified wastewater. The concentration of these emulsified wastewater is generally relatively high. If it is directly discharged, it will cause great pollution to the surrounding environment. Therefore, it is necessary to ado...

AI Technical Summary

Problems solved by technology

The chemical method has mature technology, a wide range of applicable scales, and thorough demulsification, but the consumption of chemicals for demulsification is large and the operating cost is high

Although the high-voltage electrostatic demulsification process has certain effects, the treatment efficiency is relatively low, and there are also certain limitations on the scale of use

[0004] Patent application number 200610046997.X discloses a "high-efficiency crude oil dehydration treatment system and dehydration treatment method". This method uses two devices to complete demulsification, but there are still long process routes, large floor space, and long cycle times. Disadvantages such as poor running stability

[0005] Patent No. 200720036202.7 discloses a demulsification device for high-concentration emulsified wastewater. It is equipped with an ultrasonic generator and a dosing pump on both sides of the top of the demulsification tank, and an oil collection tank is installed on the top of the demulsification tank. Through this structure, the It achieves compact equipment, small footprint, and reduces the use of demulsifiers through the synergistic effect of ultrasonic demulsification and chemical demulsification. However, the demulsification effect of this process and structure is not ideal during normal operation, and there are still some problems. Disadvantages such as large consumption of chemicals and high operating costs
