Description

The invention relates to shipbuilding, in particular to devices for heating process water on an oil tanker, and can be used in washing systems of cargo tanks, heating oil and fuel.

The purpose of the invention is fuel economy for heating process water, improving the reliability and safety of operation of the device.

The drawing shows a device for heating process water on an oil tanker.

The storage tank 1 is located in the tank sump 2. On their adjacent bulkhead, a shut-off element is installed in the form of a valve 3. In the storage tank 1, a chamber 4 is enclosed, in which a contact heat exchanger 5 with a gas pipeline 6 is installed, located in the explosion-proof zone of the vessel, which are for example, engine room or boiler room. A combustion chamber 7 with a nozzle 8 is connected to the gas pipeline 6.

A nozzle 10 is located above the nozzle 9 and is connected to the discharge pipe 11 of the circulation pump 12.

A receiving pipe 13 of the hot water pump 14 is connected to the lower part of the contact heat exchanger 5, the discharge pipe 15 of which is connected to the storage tank 1. The chamber 4 is connected by a pipe 16 to the discharge pipe of the pump 12, the receiving pipe 17 of which is connected to the tank-accumulator - 1. In the upper part the chamber with an overflow pipe 18 is connected to the tank accumulator 1, an expansion shaft 19 is installed above the overflow pipe 18, which is connected by the pipe 20 to the exhaust pipe 21 of the heat exchanger 5. The storage tank 1 is an isolator van to reduce heat loss. The pump 22 has a receiving pipe 23 in the storage tank 1 and a discharge pipe 24 for supplying hot water to consumers, for example, washing machines 25 installed in the cargo tanks 26, which also have receiving pipes 27 of the cleaning pump 28 with the discharge pipe 29 in the tank sump 2.

The device operates as follows.

Process water after treatment in the sump 2 is transferred to the storage tank 1 through the valve 3 * Nasoye 12 circulates water from the storage tank 1 to the chamber 4 through pipelines 17 and 16, the water is overfilled through pipe 18.

Camera 4 supports the full level. The accumulated gases from the expansion shaft 19 go through pipes 20, 21 to the atmosphere.

To heat the water, the exhaust gases of the power equipment are launched into the gas pipeline 6 and the water is introduced into the atomizer 10 through pipeline I.

In the nozzle 9 of the contact heat exchanger 5, heat is exchanged between the gases rising into the exhaust pipe 21 and the water flowing into the lower part of the heat exchanger, from where water is pumped to the tank 1 through the pipes 14 through pipelines 13 and 15.

To increase the temperature and burn mechanical impurities contained in the exhaust gases, fuel is supplied to the nozzle 8 and burned in the combustion chamber 7 in a gas-air mixture, thereby increasing the purity of the gases emitted into the atmosphere. Gases from the pipe 21 can be fed into cargo tanks to inertize the airspace.

Heated process water from the accumulator tank 1 is pumped through the pipelines 23 and 24 to consumers, for example, to washing machines 25 located in the cargo tanks 26. After washing, water from the cargo tanks by the cargo pump 28 is piped through pipelines 27 and 29 to the sump tank 2 for sedimentation and processing.
