Description

Heavy oil heating device for marine internal combustion engine

technical field

The utility model technology relates to a heavy oil heating device, in particular to a heavy oil heating device for a ship's internal combustion engine.

Background technique

Known internal combustion engines have air intake and exhaust systems, the air and oil that enter are at normal temperature, and the waste gas that discharges is high temperature, and high temperature waste gas contains higher thermal energy. At present, in marine internal combustion engines, high-temperature exhaust gas can be comprehensively utilized after being processed by certain technologies, such as exhaust gas boilers, superchargers, etc. In the well-known ships and ships with relatively perfect settings, light oil is used when the internal combustion engine of the ship is started, and heavy oil is used during operation. In the ships with relatively perfect settings, hundreds of thousands of yuan have been invested to install steam heating heavy oil devices to ensure the flow of heavy oil. However, in many ships with simple settings, because hundreds of thousands of yuan was not invested in steam heating heavy oil installations when the ships were originally purchased or originally built, only light oil can be used when the internal combustion engines of ships with simple settings are started and run. And because the price of light oil on the market is far higher than that of heavy oil, and at the same time, in many ships with simple settings, the heat energy of the high-temperature exhaust gas of the internal combustion engine has not been comprehensively utilized, wasting a lot of precious energy, so the setting Simple ships have high energy consumption costs and lack market competitiveness. Therefore, it is necessary to explore the device for using heavy oil and light oil in the internal combustion engine of the ship, and to explore the comprehensive utilization device of the waste gas heat energy of the internal combustion engine of the ship, so as to meet the needs of the majority of users.

Invention content:

The purpose of the utility model is to provide a heavy oil heating device for a ship's internal combustion engine for ships that can only use light oil at present.

The technical scheme of the utility model is: a heavy oil heating device for a marine internal combustion engine, which is mainly composed of an air intake cylinder, an air outlet cylinder, a heating medium inlet, a heating medium outlet, an inner pipe, and an outer pipe. The inner pipe and the outer pipe form a sandwich pipe. The ends of the inner pipe are respectively connected with the air intake cylinder and the air outlet cylinder, the outer pipe is connected with the heating medium inlet and the heating medium outlet, and the heating medium is installed in the interlayer pipe.

The heating medium contained in the interlayer tube is a liquid heating medium.

The liquid heating medium contained in the interlayer tube is water.

There are 1-10 interlayer pipes composed of the inner pipe and the outer pipe, and the interlayer pipes are connected by connecting pipes.

The interlayer pipe is arranged in the fuel container, and the fuel container is provided with a heavy oil thermometer, a heavy oil inlet, and a heavy oil outlet. The heating medium inlet, the heating medium outlet, and the connecting pipe are arranged outside the fuel container. The outer tube is provided with a heating medium temperature gauge.

An exhaust gas volume regulating valve is arranged on the air inlet of the air intake cylinder.

The optimal number of said interlayer pipes is 2.

The working principle of the utility model: the heavy oil heating device of the marine internal combustion engine of the present utility model utilizes the heat energy of the waste gas in the exhaust pipe of the marine internal combustion engine to heat the inner tube, and the inner tube heats the heating medium in the interlayer tube, The heating medium heats the outer tube, and the outer tube heats the heavy oil, and the heated heavy oil is used by the internal combustion engine of the ship. The high-temperature exhaust gas discharged from the ship's internal combustion engine flows into the intake cylinder through the pipeline, and then flows out from the outlet cylinder through the inner pipe. The temperature of the heavy oil in the fuel container can be adjusted by controlling the exhaust gas volume through the exhaust gas volume regulating valve, and adjusting the temperature of the heavy oil. It can also be adjusted by adjusting the temperature of the heating medium. heavy oil temperature.

Beneficial effects of the present utility model: the heavy oil heating device of the marine internal combustion engine of the present utility model has the following advantages, one is that the effect of heating the heavy oil is good, and a ship of thousands of tons only needs one to two heavy oil heating devices. The 2nd, this heavy oil heating device investment is few, and the heavy oil heating device of a ship of thousands of tons is just feasible as long as tens of thousands of yuan, and its price is only about 30% of the steam heating heavy oil device of the same tonnage ship; The heavy oil heating device comprehensively utilizes the heat energy of the exhaust gas of the internal combustion engine to save energy and reduce costs; fourth, the existing ships that can only use light oil can use light oil and heavy oil, greatly reducing fuel costs; fifth, the structure is simple and easy to use , safety, and maintenance costs are very low, with good social and economic benefits and promotional value.
