Embodiment Construction

[0008] The differential air bubble separation device for kitchen waste grease involved in the present invention is realized through the following steps:

[0009] The oil-water mixture in the food waste treatment process enters the storage tank (1) through the inlet, and stops the water when it enters about 10mm below the defoamer (7), and it is connected to the difference on the other side of the storage tank (1) The bubble generator (5) starts to work, and the differential bubble generator (5) can generate bubbles of 4 different particle sizes within the particle size of 10~100μm through the control of the frequency conversion motor (2), which are placed in the storage tank (1) Bubble release (6) at the bottom to release. And the air bubble releaser (6) also controls the temperature of the storage tank (1) through the connected hot air stove (3) and temperature controller (4), so as to prevent the grease from solidifying and improve the efficiency of grease collection.

Abstract

The invention discloses a device and a method, relating to the separation and recycling of greases in waste liquid in the field of environmental protection. According to the distribution characteristics of greases in liquid-state objects such as water, slurry and the like, especially the existing form characteristics of greases in kitchen waste, greases are separated by using discrepant bubbles with different frequencies, sizes and temperatures, so that the efficiency of grease separation can be improved, the energy consumption can be reduced, and the device can run automatically without being limited by seasons and temperatures.

Description

Technical field [0001] The patent of the present invention involves a device and method of oil -water separation and oil recycling, which specifically involves the device and methods of oil and water separation and oil recovery in the treatment process of kitchen waste. technical background [0002] At present, a large number of kitchen waste has seriously threatened people's health and hinders the development of the city.With the increasingly prominent and control of ecological safety, food safety, personal health, etc., finding kitchen waste, reasonable disposal of kitchen waste, and protecting the ecological environment are not only the focus of the general public in recent years.It is also a hot problem under the theme of the people's livelihood during the "Two Sessions" period every year.The "Eleventh Five -Year Plan" of the National Urban Environmental Sanitation "clearly states that cities with conditions must be built with resource -based treatment facilities for food and...
