Tanker loading system
SUBSTANCE: invention relates to ship building, particularly to loading systems of whatever tankers. Proposed system comprises cargo tanks, cargo pump, pressure pipeline, suction pipeline communicated with bottom part of cargo tanks via separation tank built therein and fitted with fluid level regulator and lock valve, and air ejector communicated with cargo tank top part. Pressure pipeline comprises additional pipeline communicated via ejector with cargo tank bottom part, while separation tank lock device top part communicated with atmosphere above the ship main deck.
EFFECT: higher efficiency and reliability of proposed system.
The invention relates to shipbuilding, in particular to the cargo systems of tankers, including oil tankers, chemical carriers, vinovat, Aquarius and others.
Known cargo and Stripping system oil tankers engaged in the receipt and delivery of cargo, as well as transfer between tanks or groups of tanks (see Reported I.L., Sazonov GN. "Special systems of oil tankers" Leningrad Shipbuilding, 1966. p.26.).
The main disadvantage of the cargo systems of tankers is the impossibility of complete evacuation of cargo as cargo pumps, large capacity, large diameter pipelines during the lowering of the liquid level in the tanks begin to capture the air, which leads to rupture of the thread and stop of cargo pumps. Pumping of cargo residues from a tank, not taken up by the cargo system is manufactured with the help of a wiper system, which device is essentially the same truck, but has less power and smaller diameter pipelines. This leads to significant downtime of the vessel by pumping out of the cargo, which reduces the efficiency of loading of the vessel.
Closest to the claimed is the cargo system of the tanker (see A.S. USSR, No. 1463624, 1989)that contains cargo tanks, cargo pump, discharge pipe, suction pipe, in communication with the bottom of the cargo tanks through in the held him in a separator tank unit, air ejector, communicated with the upper part of the cargo tank.
The disadvantage of this invention is the necessity of using compressed air systems, which complicates the design, as it requires the inclusion in the cargo system of additional mechanisms and pipelines.
The technical task of creating a simple, reliable and efficient freight system loading of the vessel.
The technical result is increased reliability, reduced cost and time in the operation.
It is achieved by the fact that the discharge pipe is provided with an additional pipe connected by means of ejector lower part of the cargo tank and the upper part of the locking device separation tank vyvedeniya in the atmosphere above the level of the main deck.
1 schematically depicts a cargo system loading of the vessel, General view.
Figure 2 - node I in figure 1.
Cargo system is loading the vessel has cargo tanks 1, cargo pump 2, the pressure line 3, additional pipeline 4, the suction pipe 5 is installed on the separation tank 6. Additional pipe 4 is connected through the separation tank 6 with the ejector 7 and the lower part of the cargo tank 1. The separation tank has a shut-off device 8 containing the elements of the spool 9 and 10, mounted on the rod 11 connected to the float 12. The top of the Yaya part of the locking device 8 is connected by an air pipe 13 with the atmosphere above the level of the main deck, and the lower part are connected by a pipe 14 with the ejector 7. On the upper part of the float 12 has a cone 15, corresponding to the hole 16.
Cargo system is loading the vessel operates as follows.
In the initial period of cargo tanks 1 and the separation tank 6 is filled with cargo (liquid). Float in the separation tank 12 is in its upper part, the cone 15 closes the opening 16, and the valve 10 closes the opening for flow of liquid from the cargo pump 2 to the ejector 7. During the lowering of the liquid level in the cargo tanks to above the critical receptions of the cargo pump formed vortex funnel and prohvatit air cargo system. Getting into the separation tank 6, privatively air rushes in its upper part. When the liquid level in the tank falls, after the liquid level drops, the float 12, the opening hole 16, simultaneously with the float moves the rod 11 and move the elements of the spool 9 and 10, opening access of fluid from the discharge pipe 3 cargo pump 2 additional pipeline 4. The ejector 7 sucks the air from the separation tank 6 through the pipe 14 in the cargo tank 1.
Thus, there is a rapid and reliable removal of air, a vacuum and filling the separation tank liquid. The process of removing air from the cargo system through the separation tank 6 is going on is it in the automatic mode, cargo pump 2 works steadily until the release of cargo tanks 1 from the liquid.
After the evacuation of cargo from tanks 1 is emptied separation tank 6, the float 12 is lowered down, the elements of the spool 9 and 10 move down, when this element of the valve 9 closes off the fluid supply to the ejector 7.
The positive effect is that to use the declared cargo system loading of the vessel does not require additional mechanisms, and it provides complete pumping liquid from the cargo tanks without additional time and costs.
Cargo system loading of the ship that contains cargo tanks, cargo pump, discharge pipe, suction pipe, in communication with the bottom of the cargo tanks via built into the separation tank with a mechanism for regulating therein the liquid level and shut-off device, an air ejector connected with the upper part of the cargo tank, characterized in that the discharge pipe is provided with an additional pipe connected by means of ejector lower part of the cargo tank and the upper part of the locking device separation tank bred in the atmosphere above the level of the main deck.
