Water surface floating oil recovery ship

Abstract

The invention discloses a water surface floating oil recovery ship. The water surface floating oil recovery ship comprises a hull, a floating oil collecting device and an oil and water separating device, and is characterized in that: the stem of the hull has a catamaran structure and is in a pointed cone form; the middle part to the tail part of the hull has a single hull structure; and a flow guiding channel which is recessed inward and is through in the longitudinal direction is formed in the middle of the bottom of the part which has the single hull structure. The water surface floating oil recovery ship has the advantages that: because the stem of the hull has the catamaran structure, and the flow guiding channel which is recessed inward and is through in the longitudinal direction isformed in the middle of the bottom of the part which has the single hull structure, the oil intake resistance generated in the driving process of the ship can be greatly reduced, floating oil can smoothly enter an oil and water pool, and the oil sweeping area of the ship is increased; and due to a chain type floating oil lifting device, a floating oil heating device in an oil and water separatingcabin, and two garbage filtering grids which are additionally arranged, the overall floating oil recovery ship can be applied to the floating oil with any viscosity and any thickness and has low requirements on a water surface environment, and the applicable water area is wide.

Description

technical field [0001] The invention relates to a surface oil recovery ship. Background technique [0002] Since the last century, with the wide application of petroleum products, the problem of oil pollution in oceans and rivers has become increasingly serious. The most important problem is the discharge and leakage of petroleum and its products, which seriously damages the environment and ecology of polluted waters and their coastlines. balance. In order to recover the oil slick on the water surface, many countries have invested in the research and development of oil spill emergency recovery technology, and the oil slick recovery ship is the most important equipment in this field. [0003] The application date is November 11, 2000, and the Chinese utility model patent specification No. ZL00256382.7 discloses an oil slick recovery ship, which includes a hull and an oil skimmer, and is characterized in that: the front deck of the hull has a groove, The front end of the u...

Problems solved by technology

When recovering oil spills, turn on the diversion pump, and the water surface will generate guiding water flow to offset the influence of the bow wave, and quickly lead the spilled oil to the oil collection zone. The oil leaks out of the grid, and the oil adheres to the oil recovery belt, which greatly improves the recovery rate of the spilled oil. However, due to the use of the oil recovery belt to collect oil, there is a requirement for the viscosity of the slick oil. For those thinner oil slicks, use the oil recovery belt The effect of collecting oil is not good, and the oil sweeping surface is relatively small

[0004] In addition, a Chinese utility model patent specification with the application date of August 22, 2008 and the patent number ZL200820135352.8 discloses a water surface oil slick recovery device, which is applied to the water surface oil slick recovery operation. Plates, conical tubes, side plates and bottom plates are welded into an airtight box, and a rear baffle is welded at the rear end of the two side plates. The shape of the bottom plate is an inclined plane. The oil inlet is formed, and a conical cylinder is welded on the bottom plate to form an oil slick channel. The oil collection tower is welded on the top of the conical cylinder. There are oil delivery system and vacuum system on the top plate of the oil collection tower, and the oil slick recovery device floats. On the water surface, the oil-water separation is carried out in a closed oil collection tower, which is not affected by the ship's turbulence and waves, and can recover oil slicks with different viscosities and oil film thicknesses; however, this device has requirements for the water surface environment, and there are more garbage on the water surface In the oil slick area, the garbage and oil slick are sucked into the oil collection tower and it is easy to cause blockage
