Description

[0002] Methanol fuel is a kind of clean fuel actively explored by shipping industry to cope with emission reduction pressure, which has many advantages such as clean and environmentally friendly, high combustion efficiency, economical and practical, high safety, etc. In the shipping industry, since methanol fuel belongs to low flash point fuel and has toxicity, therefore, in the methanol fuel system, the arrangement of pipes and accessories should ensure that the system can be completely vented and purged clean without residue. Before the methanol enters the fuel system, a filter is needed to filter the methanol. In the prior art, the filter adopts a conventional barrel-shaped filter. Since the traditional barrel-shaped filter has a body lower than the interface, there will be some liquid accumulated in the filter lower than the pipeline that cannot be blown out during pipeline purging. Therefore, the barrel-shaped filter needs to set a venting point at the lowest point of the filter and a purging port at the highest point, and connect a venting pipe and a purging pipe to ensure that the methanol residue is vented clean. Since a separate venting pipeline and control valve are needed, the preparation cost of the methanol fuel filter is high, and the maintenance and operation convenience and reliability are poor, so it needs to be improved.

Both ends of the filter mounting pipe are integrally formed with flanges. Several connection ports are opened through the flanges along the thickness direction to facilitate quick connection between the filter mounting pipe and the external pipeline.

[0030] Reference Figure 1 The filter mounting tube has an integrally formed vertical mounting tube on its top wall. The vertical mounting tube and the filter mounting tube have a T-shaped cross section. The filter body is installed inside the vertical mounting tube. The filter body is located inside the filter mounting tube and has a filtrate slope on the side facing the liquid inlet to allow methanol fuel to enter for filtration and to facilitate subsequent purging and venting of methanol fuel.

The locking nut is rotated to make the locking nut press against the clamping plate, thereby pressing the clamping plate against the surface of the sealing cover, thus realizing the quick fixation of the sealing cover and the vertical mounting tube.

[0033] Reference Figure 1 The sealing cap has a vent opening along its thickness direction, and a vent plug is installed inside the vent to maintain the balance of air pressure inside and outside the pipeline. A pull ring is installed at the top of the sealing cap for easy operation by staff.
