[0002] Diesel generator power stations are important equipment and facilities for power supply guarantee for defense, civil air defense and other protective projects. When the diesel generator power station unit is running under certain working conditions, it will produce a large amount of black smoke, blue smoke, white smoke, etc., which will cause obvious visible light exposure symptoms. At the same time, the high-temperature flue gas discharge will cause obvious thermal infrared exposure symptoms. In order to strengthen the protection and camouflage of the power station and prevent the power supply from being interrupted due to attack and damage, it is necessary to take effective camouflage and protection measures for the power station.

[0003] At present, the main smoke elimination and cooling thermal infrared camouflage treatments include spraying smoke elimination and cooling, electrostatic smoke elimination and dust removal, and black smoke capture. However, due to the fact that a single measure may require a large amount of water and easily produce a large amount of white mist, or the electrostatic smoke elimination and dust removal equipment is too large, the technology is too complicated, resulting in poor adaptability, or DPF black smoke capture can only eliminate smoke and purify but not cool and camouflage, none of them can comprehensively and effectively solve the diesel generator camouflage protection problem. At the same time, the waste heat of the power station cannot be effectively utilized, resulting in energy waste. Utility Model Content

[0046] When this embodiment is implemented, the exhaust gas discharged by the diesel generator set 20 is purified by the filter bed 2 in the smoke elimination and cooling camouflage device for black smoke particles, and the exhaust gas temperature is reduced by heat exchange of the finned tubes 3 in the filter bed 2, so that the black smoke particles are easier to capture, and the black smoke particles generated by the diesel generator set are further eliminated to avoid visible light exposure caused by the discharge of a large amount of black smoke. The high-temperature exhaust gas exchanges heat with the finned tubes, firstly to reduce the exhaust temperature and reduce the signs of thermal infrared camouflage exposure of the exhaust, secondly to reduce the intensity of thermal infrared radiation of the flue gas, and thirdly to recycle the exhaust waste heat to achieve energy saving and high efficiency. Waste heat utilization equipment includes terminal radiators, water heaters, hot water taps and fan coils, etc., which are installed at water and heating locations in the project. The waste heat recovered by the smoke elimination and cooling components is transported to waste heat utilization equipment such as water heaters, hot water taps, and hot water tanks in the form of water.

[0049] In this embodiment, a first support plate 4 and a second support plate 5 are also included; the first support plate 4 is connected to the inner wall of the housing 1 and is arranged near the smoke inlet 101; the second support plate 5 is connected to the inner wall of the housing 1 and is arranged near the smoke outlet 102, a purification chamber is formed between the first support plate 4 and the second support plate 5, and a plurality of filter beds 2 are arranged between the first support plate 4 and the second support plate 5, the first support plate 4 is provided with a smoke inlet 401, and the second support plate 5 is provided with a smoke outlet 501, so that high-temperature smoke enters through the smoke inlet and passes through at least one filter bed for adsorption and heat exchange before being discharged from the smoke outlet. By providing the first support plate 4 and the second support plate 5, the filter bed can be installed more stably to ensure the black smoke purification effect.

Figure 1-Figure 4As shown, in this embodiment, the filter bed 2 is arranged in a bow shape, and the two ends of each filter bed 2 are respectively connected to the first support plate 4 and the second support plate 5, and the other two ends of each filter bed 2 are respectively in close contact with the side wall of the shell 1 distributed along the second direction, and the central axis of the shell 1 along the first direction and the central axis of the shell 1 along the second direction are located in the same horizontal plane, and the smoke inlet 401 and the smoke outlet 501 are alternately arranged along the spacing between two adjacent filter beds 2. The first support plate 4 and the second support plate 5 are arranged to facilitate the installation of the filter bed, and the surrounding walls of the filter bed are respectively sealed and connected with the first support plate 4, the second support plate 5 and the side wall of the shell to avoid air leakage. By alternately arranging the smoke inlet 401 and the smoke outlet 501 along the gap between two adjacent filter beds, it is ensured that the high-temperature flue gas entering the purification chamber can be discharged after being filtered by at least one filter bed, thereby ensuring the purification effect of black smoke particles.

[0051] like Figure 5 As shown, the filter bed 2 includes a support 201 and a fiber filter felt 202. The fiber filter felt 202 is folded in an M shape in the support 201. This arrangement can increase the contact area between the black smoke and the fiber filter felt and improve the purification effect. The finned tube 3 is embedded in the folded gap of the fiber filter felt 202.
