Ship main engine light/heavy diesel conversion device and system

Abstract

The invention discloses a ship main engine light / heavy diesel conversion device. The ship main engine light / heavy diesel conversion device comprises a water tank body and an oil filter device arranged in the water tank body; a water inlet and a water outlet are formed in the water tank body; the oil filter device comprises an oil cavity barrel body, a filter net framework and a clean oil chamber barrel body; an oil connection opening is formed in the oil cavity barrel body; the opening at the upper end of the oil cavity barrel body is fixedly provided with a sealing plate; the filter net framework which is wrapped with a filter cloth is arranged and inserted in the oil cavity barrel body from the middle part of the sealing plate; a compressing plate is arranged on the upper part of the filter net framework; a sealing component is arranged between the compressing plate and the sealing plate; the upper part of the clean oil chamber barrel body is connected with an upper cover plate, and the lower part of the clean oil chamber barrel body is connected with the compressing plate, so that a clean oil chamber is formed; a clean oil outlet is formed in the clean oil chamber; and an oil outlet in the clean oil chamber is connected with the filter net framework. The ship main engine light / heavy diesel conversion device has the characteristics that fuel oil heating, filtering and supplying are integrated in the integrated working mode; waste heat generated during work of the main engine is fully utilized to heat fuel oil continuously and circularly; the qualified fuel oil supplying standard of a diesel engine is reached, and the requirement on the oil amount needed by the diesel engine is met.

Description

technical field [0001] The invention relates to the field of ships, in particular to a light / heavy diesel conversion device and system for a ship main engine. Background technique [0002] The so-called heavy oil used in existing ships is not second oil, but a kind of miscellaneous oil. This oil has a certain viscosity when the temperature is low, and its fluidity is also very poor, and its penetration is also very low. But when the temperature reaches above 40°C, it will change its unique state. [0003] At present, there are basically three types of fuel conversion products installed on board: 1. The heating rod directly heats the fuel and then filters it in the filter. This is a serious violation of the relevant regulations of the "Code for the Use of Marine Fuel Oil", and the safety factor is zero; 2. Use the heating belt to heat outside the oil cylinder cavity. Although it is not in direct contact with the oil, there is a huge hidden danger. It is very likely that the ...

Problems solved by technology

[0004] In summary, the existing three fuel conversion forms have the following defects in addition to the loss of equipment and the inability to guarantee safe operation: first, the heating temperature cannot meet the actual use requirements, and the oil temperature drops too fast; second, due to The temperature is not up to the standard, resulting in poor filtering effect and insufficient fuel supply. Therefore, the diesel engine will appear idle and surge phenomenon from time to time, which will cause certain damage to the machinery. The filter is installed far away from the machine, the pipeline is too long, and the heat loss of heavy oil is extremely large in actual operation, which affects the filtration accuracy and oil production, and increases the difficulty of maintenance, repair and operation for the operator. , it is very inconvenient to manage
