Description

The invention relates to vessels intended for cleaning water bodies from oil products spilled on their surface.

A vessel for collecting oil products from the surface of the water is known, containing a receiving tank communicated through cutouts made in the side of the vessel at the 9th waterline, in the outside water, outlet channel, jDacnonojkeHHbiu. in the stern of the vessel and communicating the receiving tanks with seawater below the vessel's current line, the tank for collected oil products, the device for feeding the pure sorbent into the tank, and the device for removing saturated sorbent from it, as well as the oil separation unit from the sorbent tl3

The disadvantage of this vessel is the low productivity of refining from petroleum products.

The purpose of the invention is to improve the performance of the vessel.

X cauldron goal is achieved by the fact that in the vessel containing the receiving tank, communicated through the notches, Hbie was made onboard the vessel at the level of its wind line with seawater, an outlet channel located in the stern of the vessel and co-operation with seawater below the Acts of the ship’s waterline, a tank for softened oil products, a device for feeding the receiving sorbent into the receiving tank and a device for removing saturated sorbent from it, as well as a block for separating oil products from the sorbent, a device for removing sorb The nta from the receiving tank contains an expansion chamber with an exhaust fan installed in it, communicated via an air duct to the aft part of the receiving tank, and an oil separation unit from the sorbent is located in the expansion chamber and is connected to a device for supplying a clean sorbent to the receiving tank, which is filled with a channel located in the bow of the vessel.

The drawing schematically depicts the ship, the & tions view. .

The vessel contains a steel hull 1 capable of withstanding swimming in ice. , At the waterline, the vessel is equipped with double borg. Inside the ship's hull 1, there is located & a receptacle 2., in order to give strength in which the necessary stiffening elements are installed. The ship's borg has helix-shaped notches 3 wide, 2–3 cm wide: at intervals along the side, which are located above the waterline and the bottom of the notch is HniJife waterline. Receiving container 2 is connected to seawater with outlet 4 below the waterline. The inlet and outlet openings of the exhaust channel 4 are closed by slats. A water jet 5 is installed in the exhaust channel 4. The receiving container 2 is connected by a duct 6 to a expansion chamber 7, which is connected to a powerful exhaust fan 8. In the expansion chamber 7, a unit for separating oil products from a sorbent is mounted, including a net conveyor 9 and a squeezing mechanism 10. Receiving container 2 by channel 11 is connected to a squeezing mechanism 10. A sorbent is placed on the surface of the liquid in the receiving container 2 in the form of pieces, for example) elastic polystyrene {Le anew foam polyclass. The vessel is equipped with a propeller 12. Air duct 6 is made with a cut-out 13 covered by a crate 14 located on the flat part of the duct 6 slightly higher than the waterline and equipped with an adjustable damper 15. Receiving tank 2 co-operates through the cut-out 13 with modular containers 16 located on both sides of the ship below the waterline. In the receiving tank 2 ustashvpeny partitions 17.

The collection of petroleum products from the water quality is as follows.

Since the cutouts 3 in the outer side of the ship are located on both sides of the waterlines, outboard water with oil products floating on its surface, the MI enters the receiving tank 2 through the cutouts. When turned on (in the forward direction, the water from the bottom receiving tank 2, is pumped overboard through channel 4. Due to this, a constant decrease / water level in the receiving tank 2 is created, which causes a constant influx of surface water with floating oil and receiving tank 5 The screw 8 in the expansion chamber 7 creates a vacuum in the duct 6 and the receiving tank 2. BO3ffyx is sucked through a portion of the cutouts 3 located above the water surface, which contributes to pulling petroleum products into the receiving tank 2, where a high air flow is created above the water surface. Feed channel 11 into a clean sorbent, for example, pieces of elastic polyurethane foam that is thrown out.

on the goodness of the fluid in the intake & m, bone 2 and moves along the angle of the fluid to the entrance to the duct b. Joining the co-tact with petroleum products, the sorbent absorbs absorbing gas. For example, a 5 mm thick layer of diesel fuel is absorbed in 2-3 seconds when the temperature of the water is used up. The sorbent absorbs water in small quantities: only when it is kept for a long time on the brightness of the water, and since the sorbent is in. The receiving tank 2 is only a few, it does not absorb water. In order to create a greater visibility and honor of the middle part of the sorbent 1v shn lenn with extraordinary pores, Absorb oil product sorbent flow Boc "ysa flow into the duct 6, where due to the constriction the air flow rate increases, and the sorbent: through the duct 6 moves to the expander :) chamber 7, in which the flow rate decreases, and the sorrant falls onto the mesh conveyor 9 of the pressing mechanism 1O. Exhaust air passing through the fan 8 goes into the atmosphere. Sorbent yrotsodit through shafts of squeezing medanism Y. Compressed petroleum products go to

, bottom of the expansion chamber. 7. An annealing mechanism is mounted in compliance with

airtightness of the expansion chamber 7. Sorbent after pressing oil products

again returns through channel 11 to the receiving tank 2. The entire cycle is continuously repeated.

The collection of low-viscosity diesel oils from the surface of the water in the receiving tank is ensured only by countering the oil products with a sorbent. Collecting viscous oil products, or collecting them among the ices, where the cold increases the ecosystem of various petroleum products, is ensured by a constant push: neither floating oil products by the air flow and air flow to the entrance to the duct 6. In the latter, a cutout 13 is made, the grating is 14 Thus, between the receiving tank 2 and the collecting tanks, the tanks 16 have a low gentle threshold through which the viscous floating oil products are blown off and scooped in the tank 16. The cut-out 13 is inverted by a flap 15, the position of which is adjusted. Thus, the threshold height is made variable. Under heavy rolling, the notch 13 can be closed to prevent water from entering the collection containers 16.

Installed in the receiving tank 2 partitions 17 dispel the excitement of the liquid in the tank.

Such an execution of the vessel allows to increase its productivity, especially if it is in conditions of agitation and the presence of ice floes.
