The sources are relatively wide. Fuel gases often contain impurities such as moisture, particulate matter, and sulfides. In order to ensure that the fuel gases meet the requirements of the engine, the gas entering the internal combustion engine needs to be pretreated.

[0003] Traditional gas pretreatment devices typically consist of a series of independent equipment such as cyclone separators and desulfurization towers, with each independent equipment connected by pipelines.

[0004] Traditional gas pretreatment units occupy a relatively large area, and each independent device and connecting pipeline requires a certain amount of space. In addition, the cost of purchasing, installing and maintaining the equipment is relatively high.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Inside the cylindrical body, from bottom to top, a guide pipe, fiber felt, activated carbon filter element, and a gas collecting cylinder are installed sequentially.

The bottom of the activated carbon filter element is sealed, and an outlet is provided at the top. An annular hanging plate is fixedly installed at the outlet, and the annular hanging plate of the activated carbon filter element is attached to the bottom of the gas collecting cylinder.

[0009] Furthermore, the centerline of the guide pipe is set vertically, and an annular baffle is installed between the guide pipe and the inner wall of the cylinder, with the baffle positioned near the top of the guide pipe.

[0010] Furthermore, the gas inlet pipe is arranged along the tangential direction of the cylinder.

[0011] Furthermore, a waste discharge port is provided at the bottom of the cone shell.

[0012] Furthermore, a perforated plate is installed at the bottom of the fiber felt, which is fixedly installed on the inner wall of the cylinder and located above the guide pipe.

[0013] Furthermore, the gas collecting cylinder has an inverted conical structure, with the top of the gas collecting cylinder fastened to the top of the cylinder body.

[0014] Furthermore, a cover plate is installed above the gas collecting cylinder, and a clamping element is provided on the top of the cover plate.

[0015] Furthermore, the side of the clamping component is connected to the swing arm mechanism.

[0016] Furthermore, a sleeve is fixedly installed on one side of the top of the cylinder, and a gas outlet pipe is inserted inside the sleeve.

[0017] Furthermore, the gas outlet pipe is connected to the sleeve via a flange, and the inner end of the gas outlet pipe slides through the inner cavity of the gas collecting cylinder.

Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown in the figure, this utility model provides a gas pretreatment device for internal combustion engine power generation, including a vertical cylindrical body 1, a conical shell 2 fixedly installed at the bottom of the cylindrical body 1, and a guide pipe 3, a fiber felt 7, an activated carbon filter element 8 and a gas collecting cylinder 9 installed sequentially from bottom to top in the inner cavity of the cylindrical body 1.

[0029] The centerline of the guide pipe 3 is set vertically. A ring-shaped baffle 4 is installed between the guide pipe 3 and the inner wall of the cylinder 1. The baffle 4 is set near the top of the guide pipe 3. A cavity is formed between the outer wall of the guide pipe 3 and the inner wall of the cylinder 1. A gas inlet pipe 5 connected to the cavity is provided on the outer wall of the cylinder 1. The gas inlet pipe 5 is arranged along the tangential direction of the cylinder 1.

[0030] The bottom of the cone shell 2 is provided with a waste discharge port 16.

[0031] When the gas enters the cavity, it generates a swirling flow. Moisture and solid particulate impurities in the gas are thrown toward the wall and accumulate under the action of centrifugal force, and are discharged from the discharge port 16. The gas, after being dehydrated and initially removed from impurities, is discharged upward from the central guide pipe 3.

[0032] The fiber felt 7 is used to intercept solid particulate impurities in the gas, thereby achieving secondary removal of solid particulate impurities.

[0033] A perforated plate 6 is installed at the bottom of the fiber felt 7. The perforated plate 6 is fixedly installed on the inner wall of the cylinder 1 and located above the guide pipe 3. The perforated plate 6 can both distribute air and support the fiber felt 7.

[0034] The activated carbon filter element 8 is made from coal-based activated carbon through a high-temperature sintering process. It has both mechanical filtration and chemical adsorption functions and can effectively remove hydrogen sulfide and other sulfides from fuel gas.

[0035] The activated carbon filter element 8 has a bottom sealing device and an air outlet at the top, with a ring-shaped hanging plate 15 fixedly installed at the air outlet.

[0036] The annular hanging plate 15 of the activated carbon filter element 8 is attached to the bottom of the gas collecting cylinder 9. The gas collecting cylinder 9 has an inverted conical structure, and its top end is fastened to the top of the cylinder body 1. The gas collecting cylinder 9 is used for the collection of clean fuel gas.

[0037] A cover plate 10 is installed on top of the gas collecting cylinder 9. A clamping member 11 is provided on the top of the cover plate 10. The clamping member 11 tightly fastens the cover plate 10 and the gas collecting cylinder 9 to the top of the cylinder body 1 to prevent gas leakage. The side of the clamping member 11 is connected to the swing arm mechanism 12. The swing arm mechanism 12 facilitates the opening of the cover plate 10 to the side, making it easy to replace the activated carbon filter element 8 and fiber felt 7 inside the cylinder body 1.

[0038] A sleeve 14 is fixedly installed on one side of the top of the cylinder 1. A gas outlet pipe 13 is installed inside the sleeve 14. The gas outlet pipe 13 is connected to the sleeve 14 through a flange. The gas outlet pipe 13 is easy to install and remove. The inner end of the gas outlet pipe 13 slides through the inner cavity of the gas collecting cylinder 9.

[0039] The specific working principle of this utility model is as follows:

[0040] This utility model integrates dehydration, desulfurization and filtration functions.

[0041] The gas enters the cylinder 1 and generates a swirling flow, removing moisture and solid particulate impurities from the gas. After dehydration and preliminary impurity removal, the gas is discharged upward from the central guide pipe 3. After discharge, the gas is evenly distributed to the fiber felt 7 by the orifice plate 6. The fiber felt 7 intercepts solid particulate impurities in the gas, achieving a second removal of solid particulate impurities. Then the gas passes through the activated carbon filter element 8, which removes sulfides such as hydrogen sulfide from the gas. The clean gas is collected in the gas collecting cylinder 9 and finally output to the internal combustion engine through the gas outlet pipe 13.

[0042] The filter material in this utility model is easy to replace. When replacing, the cover plate 10 is opened to the side under the action of the swing arm mechanism 12. Then the air collecting cylinder 9 and the activated carbon filter element 8 can be removed upwards, and then the fiber felt 7 can be removed upwards. The operation process is convenient.

[0043] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
