Description

Technical Field

[0001] The utility model relates to the technical field of ship fittings, and more specifically, to a ship exhaust pipe device equipped with a VOCs tail gas treatment device. Background Technique

[0002] VOCs refers to volatile organic compounds with a saturated vapor pressure greater than 70 Pa at room temperature and a boiling point below 260 °C under normal pressure existing in the air, mainly including non-methane total hydrocarbons, oxygen-containing compounds, halogenated hydrocarbons, nitrogen-containing compounds, sulfur-containing compounds, etc. Under sunlight irradiation, they may combine with other pollutants to form atmospheric composite pollutants, inducing serious environmental problems such as haze and photochemical smog.

[0003] At present, the engines of ships in China mainly use diesel engines, and generally use "heavy oil" as fuel. During the loading, unloading and cruising processes of ships, the combustion and volatilization of engine fuel will emit VOCs into the atmospheric environment, mainly including alkanes (such as propane) and aromatic hydrocarbons (such as benzene, toluene, xylene). In the prior art, the exhaust pipes of ships are not equipped with VOCs tail gas purification devices, and the tail gas of ships cannot be purified during use, resulting in the discharged tail gas polluting fresh air and causing serious harm to people's physical health.

[0006] The VOCs tail gas treatment device includes a treatment pipe and a VOCs intake porous mixing guide plate, a VOCs catalyst cushion layer, and a VOCs catalyst arranged in the treatment pipe. The VOCs intake porous mixing guide plate is located before the VOCs catalyst, and the VOCs catalyst cushion layer is located between the VOCs catalyst and the inner wall of the treatment pipe.

[0007] In a preferred embodiment, the treatment pipe includes an intake straight pipe, an intake taper pipe, a main pipe body, an outlet taper pipe, and an outlet straight pipe connected in sequence.

[0008] In a preferred embodiment, the VOCs catalyst cushion layer and the VOCs catalyst are located in the main pipe body.

[0009] In a preferred embodiment, the intake straight pipe is connected to the ship VOCs tail gas inlet pipe through a flange joint.

[0010] In a preferred embodiment, the outlet straight pipe is connected to the ship VOCs tail gas outlet pipe through a flange joint.

[0011] In a preferred embodiment, a sensor interface is provided on the treatment pipe.

[0012] In a preferred embodiment, the VOCs intake porous mixing deflector is oriented towards the intake direction, and the diversion holes on the VOCs intake porous mixing deflector evenly cover the plate surface and have the same size.

[0013] In a preferred embodiment, a fixed base is provided on the treatment pipe, and the fixed base is fixedly connected to the VOCs tail gas treatment device.

[0014] The beneficial effects of the technical solution of the present utility model are:

[0015] In this solution, a VOCs tail gas purification device is provided on the ship exhaust pipe, so that the VOCs tail gas emitted by the ship engine can be removed, avoiding the harm to people's physical health caused by the emission of VOCs tail gas.

[0016] A VOCs intake porous mixing deflector is provided in the treatment pipe, making the mixing of VOCs gas more uniform, so that the treatment effect of the VOCs by the ship tail gas treatment device is better. The VOCs catalyst cushion layer provided on the outer periphery of the VOCs catalyst can ensure the sealed connection between the VOCs catalyst and the inner wall of the treatment pipe, preventing the gas from flowing out of the treatment pipe without being treated.

[0020] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the convenience of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

The VOCs intake porous mixing deflector 35 faces the intake direction, and the diversion holes on the VOCs intake porous mixing deflector 35 are evenly distributed on the plate surface and have the same size. The gas passes through the diversion holes, which can make the gas disperse evenly. The evenly dispersed gas then enters the VOCs catalyst 37 for treatment and purification. The VOCs catalyst cushion 36 provided on the outer periphery of the VOCs catalyst 37 is made of a deformable material, which can ensure the sealed connection between the VOCs catalyst 37 and the inner wall of the treatment pipe, and prevent the gas from flowing out of the treatment pipe without being treated.
