Oil-water separating device and device thereof for separating oil from kitchen sewage

Abstract

The invention discloses an oil-water separating device, which has a barrel structure with a closed top and an open bottom. The barrel structure comprises at least four adjacent material layers (26, 27, 28 and 29) which are adjacently joined from the inside to the outside in turn: a frame layer (26), an emulsion breaking mesh (27), a lipophilic fiber (28) and a wire mesh (29), wherein the frame layer, the emulsion breaking mesh and the wire mesh all are made of stainless steel materials; the mesh of the emulsion breaking mesh is 40-100; and the mesh of the wire mesh is 60-120. The invention has simple structure and good oil-water separating effect; the physical method used for processing the kitchen sewage containing animal and vegetable fats not only can recover the animal and vegetable fats, but also can avoid the environment pollution caused by the kitchen sewage containing the animal and vegetable fats being drained to the civil pipeline network and avoid the problem of secondary pollution caused by the chemical processing method; the invention also prevents impurities contained in the kitchen sewage precipitating on the inner wall of a filter element so as to avoid the blockage of the filter element, reduce the maintenance of the device and improve the working efficiency.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a device for separating oil from sewage discharged from kitchens, city hotels and restaurants on passenger ships and oil separation equipment with the device. Background technique [0002] With the continuous improvement of people's material life, the number of large restaurants and hotels in cities and towns continues to increase; after my country's accession to the WTO, exchanges with other countries in the world have increased, and the rate of passenger ships and ocean liners going to sea has also continued to increase, so restaurant discharge water has a negative impact on the urban environment. The pollution problem of passenger ships and the pollution of the ocean by food waste from passenger ships have become a serious problem in today's society and have affected international relations with exchange countries. [0003] On the other hand, it is also an important issue to save wa...

Problems solved by technology

The common problem of the grease trap is that the oil-water separation effect is poor, and the odor and pollution impurities cannot be removed, resulting in environmental stench. Therefore, it is not convenient to install a grease trap in places with high environmental sanitation requirements.

[0007] Since there are various impurities in the kitchen sewage, such as large solid dirt and fibrous dirt, which flow directly into the oil separator, it is very easy to entangle the submersible sewage pump of the oil separator and cause blockage of the inlet pipe. Frequent dredging and maintenance Submersible sewage pumps and water inlet pipes waste manpower and financial resources, and bring stability to the use of oil separation equipment, reducing equipment work efficiency

[0008] In addition, after the oil-water separation device has been used for a period of time, the impurities contained in the kitchen sewage will accumulate on the inner wall of the filter element in the oil-water separation device, thereby blocking the filter element, which will also affect the working efficiency of the equipment, and even cause the filter element to fail. Work

[0009] In particular, the above-mentioned oil separator cannot discharge the separated oil and water at the same time, thus reducing the work of treating kitchen waste water
