Automatic oil-water separating device and method

Abstract

The invention discloses an automatic oil-water separating device and an automatic oil-water separating method. The device mainly comprises an oil suction rope, an oil suction rope transmitting channel, an oil guide groove, an oil storage tank and remote control guide rails, wherein the oil suction rope consists of a natural fiber inner core, an ultrafine polypropylene fiber felt and an open zipper; the oil suction rope transmitting channel, the oil guide groove and the oil storage tank are of an integrated structure; the oil suction rope transmitting channel consists of rollers, an oil guide opening and a channel wall; one part of the oil suction rope is arranged in the oil suction rope transmitting channel and moves in a reciprocating mode via driving of the rollers; the remote control guide rails consist of guide rail bearings, floating blocks and remote control propellers; a plurality of remote control guide rails are installed on the oil suction rope at an equal interval. According to the invention, integrated circulation operation of oil enclosing, oil suction and oil recycling is realized efficiently, simply and conveniently; oil suction raw materials are plant-type fiber materials and cannot cause secondary pollution to the environment; the hot-pressing nano polypropylene fiber felt is excellent in mechanical performance and can be used repeatedly. The device can be suitable for multiple fields of oil overflow at water areas of rivers, lakes, seas and the like as well as waste oil recycling in factories and the like.

Description

technical field [0001] The invention relates to an automatic oil-water separation device and method, which are mainly used for oil-water separation of factory wastewater and emergency treatment of oil spill accidents in waters such as rivers, lakes and seas, and belong to the technical field of oil-water separation. Background technique [0002] In recent years, marine oil spill accidents have occurred frequently. Every oil spill accident has caused huge damage and loss to human safety, ecological environment, oil resources and economic development. In 2010, more than 27 million gallons of oil were spilled in the Gulf of Mexico. In 2013, the Qingdao oil pipeline explosion caused a direct economic loss of 750 million yuan. The current methods to deal with oil spills in waters mainly include physical, chemical and biological methods. The chemical method based on in-situ combustion will cause secondary pollution to the environment and is not conducive to the recycling of oil;...

Problems solved by technology

The chemical method based on in-situ combustion will cause secondary pollution to the environment and is not conducive to the recycling of oil; the biological method based on throwing oil-degrading bacteria is high in cost and low in efficiency; the physical method is the most widely used, and generally First use the oil boom to surround the spilled oil to prevent the continued spread of the spilled oil in the water area, then throw oil-absorbing felt to the sea surface to absorb the floating oil on the sea surface and then transport it away, and finally recover the spilled oil by extrusion or vacuum separation

The physical method is timely, fast, environmentally friendly and efficient to deal with marine oil spill accidents, but its operation procedures are complicated, and the commonly used polypropylene oil-absorbing felt cannot be biodegraded, and the residue after repeated use will cause environmental damage after being landfilled or incinerated. Secondary pollution
