[0002] Confined space dust removal systems are used to remove dust from gases within confined spaces such as ship cabins. Based on their dust removal principles, dust removal systems can be categorized as either electrostatic or bag-type. Electrostatic dust removal systems suffer from significant efficiency fluctuations and high equipment costs. Bag-type dust removal, on the other hand, is significantly impacted by the type of filter media and the effectiveness of dust removal. Frequent filter media replacement is often required, resulting in high operating and maintenance costs.

DETAILED DESCRIPTION

[0021] The present patent application is further described below with reference to the embodiments.

[0022] like Figure 1-3 As shown, a high-efficiency dust removal device in a confined space includes a main body shell 3 arranged on a main body base 4. The main body base 4 adopts three-point support, and the structure is more stable. The upper part of the main body shell 3 is a cylindrical structure, and the lower part is an inverted conical structure, which mainly serves to isolate the inside and the outside. A drain outlet 10 is provided at the bottom of the main body shell 3 for discharging sewage.

[0023] A hollow cylindrical support pipe rack 8 is provided inside the main housing 3, which mainly serves as a support. A spray main pipe 5 is provided inside the support pipe rack 8, on which a spray branch pipe 7 is provided, and on which atomizing nozzles 9 are distributed. The spray main pipe 5, the spray branch pipe 7, and the atomizing nozzles 9 mainly serve to introduce dust removal liquid and generate dust removal spray. Specifically, the spray main pipe 5 is introduced from the outside through the reserved holes on the main housing 3 and the support pipe rack 8, passes upward through the internal space of the support pipe rack 8, and is connected to the spray branch pipe 7 through the reserved holes on the support pipe rack 8. The spray branch pipe 7 is distributed on one side of the spray main pipe 5, and is parallel to each other and evenly distributed on the spray main pipe 5. The atomizing nozzles 9 are evenly distributed on the spray branch pipe 7, and the direction is clockwise when viewed from above.

[0024] A spiral upward-directing flow guide 6 is provided between the support pipe frame 8 and the main unit housing 3. Specifically, this flow guide 6 comprises, from bottom to top, an air induction plate 12, a dust removal plate 14, and a drying plate 16. Air induction plate 12, a double-layered spiral structure, is located in the lowest space of the cylindrical section of the main unit housing 3 and primarily serves to guide the movement of the dust-laden airflow. An air inlet duct 13 is provided in the main unit housing 3 between air induction plate 12 and dust removal plate 14. Dust-laden air enters tangentially from air inlet duct 13 and is forced upward by air induction plate 12 to flow in a spiral. Above the induced draft plate 12 is the dust removal plate 14. In the spiral direction, a discharge port 11 is provided between the induced draft plate 12 and the dust removal plate 14 to discharge the sewage flowing down from the upper layer to the bottom of the device. The dust removal plate 14 has a multi-layer spiral structure, and each layer is provided with a diversion port 15 to divert the sewage accumulated on each layer downward, forming a water curtain and enhancing the dust removal effect. A spray branch pipe 7 is provided between two adjacent layers of the spiral structure of the dust removal plate 14. The direction of the atomizing nozzle 9 on the spray branch pipe 7 is opposite to the direction of gas flow, and is used to perform dust removal operations on the dust-laden gas spiraling upward. The upper layer of the dust removal plate 14 is a drying plate 16, which is used to extend the air duct to achieve the effect of drying the air.

[0025] An induced draft duct 2 is provided on the top of the main body housing 3, and an induced draft fan 1 is provided on the top of the induced draft duct 2, which is used to draw out the gas to generate negative pressure, thereby driving the dust-laden gas to continuously flow upward in a spiral.

[0026] The present invention adopts reverse spray dust removal. The dust-laden gas enters from the lower air inlet pipe 13, flows upward in a spiral along the spiral induced draft plate 12, passes through the dust removal plate 14 and the spray system, enters the drying plate 16, and is finally discharged by the top induced draft fan 1 through the induced draft pipe 2. The water mist generated by the spray system flows downward in a spiral along the spiral multi-layer dust removal plates 14, and forms a water curtain at the diversion port 15 of each layer of dust removal plate 14, thereby enhancing the dust removal effect. The discharge port 11 between the induced draft plate 12 and the dust removal plate 14 is used to drain the upper layer of water to the bottom and discharge it from the bottom drain port 10 to avoid affecting the introduction of dust-laden gas. The discharged water can also be recycled.

[0027] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
