Description

TECHNICAL FIELD

[0001] The present application relates to the field of engineering camouflage protection, in particular to a vortex-eliminating tee joint and a thermal infrared camouflage smoke-eliminating device. BACKGROUND

[0002] Military underground command post diesel generator station, mobile power station and the like will generate a large amount of heat in the working process. The initial exhaust temperature of the diesel generator set is as high as 500℃ or above. Although the temperature of the exhaust gas is reduced when it passes through the exhaust pipe to the exhaust outlet, the exhaust gas temperature is still much higher than the ambient temperature. The exhaust port has obvious thermal infrared exposure signs, which is easy to be discovered by enemy infrared reconnaissance and attacked and destroyed. At the same time, the diesel generator set often emits black smoke at the initial start-up and overload operation of the power station, and blue smoke and white smoke may occur during the operation of the power station. Some power station tunnels are often accompanied by white fog due to the fact that the saturated humid air in the smoke dispersing tunnel is brought out of the tunnel by diesel exhaust. There are often problems such as surrounding people mistaking it for forest fire and reporting to the police. At the same time, it is also the main sign of target exposure.

[0003] The main technologies for dealing with the above-mentioned thermal infrared exposure signs and smoke exposure signs include: 1. Thermal infrared camouflage, which mainly uses water cooling and air layer isolation technology. Water cooling requires a large amount of water supply, which makes it difficult to popularize and apply, and the cooling effect is limited. Moreover, using water can easily produce more white fog. The air layer isolation technology represented by CN102486359A patent cannot effectively reduce the thermal infrared exposure signs of the power station. After a certain period of use, the surrounding environment still has a high possibility of infrared sign exposure. 2. Diesel black smoke treatment, which mainly uses oxidation catalytic converter (DOC), straight-through maintenance-free diesel engine exhaust particulate filter (FTF) and wall-flow diesel engine exhaust particulate filter (DPF) to remove HC, CO and particulate matter. DPF can effectively purify 70%-90% of particulate matter in exhaust gas, which is one of the most effective and direct methods for purifying diesel particulate matter. It has been commercialized internationally. Dry, wet dust collectors and spray-type smoke eliminators, dry black smoke catchers DPF are used for treatment. There is a relatively mature technical solution for black smoke treatment, which can eliminate 90-95% of black smoke and achieve certain smoke elimination effect. However, the use time of the flat station combined with engineering is short, which can easily cause the filter core to be damp or moldy, affecting the effect. Therefore, a technology that can effectively solve the problems of thermal infrared camouflage and smoke elimination to ensure the continuous operation of underground diesel generator power stations needs to be studied and solved.

The vortex elimination plate is arranged to orderly control the high temperature flue gas to be laminar flow state, avoid the direct contact between the high temperature flue gas airflow and the ventilation pipe to generate heat conduction.

[0021] 3、The smoke elimination device of the present application utilizes the ventilation fan to pressurize the gas to carry the exhaust of the diesel engine power station and the heat dissipated along the way. The high-temperature exhaust gas is pressurized by the fan to form a certain speed of gas flow beam to carry out the emission, so that the high-temperature gas does not contact the exhaust pipe, and the exhaust gas is no longer diffused and spread in an unorganized manner around the equipment camouflage house, thereby avoiding the unorganized diffusion of the exhaust gas around the equipment camouflage house, and the heat absorption of the surrounding environment, which causes the difference between the environment temperature, and becomes the sign of the enemy infrared reconnaissance.

The diesel generator set can be continuously operated for a long time without interruption, and maintenance is not required after the operation.

[0023] 5、The exhaust gas injection pipe can be discharged towards the favorable discharge direction through the elbow pipe. The device reduces the disturbance of the ventilation air flow to the dust and sundries around the equipment camouflage house by setting the anti-fouling plate, so as to avoid the dust and sundries from being sucked into the ventilation pipe. The system is isolated from the external environment by setting the first sealing assembly and the second sealing assembly, so as to avoid the humid air, animals, sundries and the like from entering the system during the shutdown of the system, reduce the daily maintenance workload of the system, and prolong the service life of the system.

[0042] As shown in Figure 3The shown thermal infrared camouflage smoke elimination device comprises a device camouflage room 13, a smoke eliminator 14, a ventilator 15, a smoke exhaust pipe 16, an exhaust injection assembly and the above-mentioned vortex elimination tee 1; the ventilator 15 is located in the device camouflage room 13, the smoke exhaust port of the power station generator set (diesel engine) is communicated with the air inlet of the smoke eliminator 14 through a pipeline, the air outlet of the smoke eliminator 14 is connected with the air inlet pipe section 4 of the vortex elimination tee 1 through the smoke exhaust pipe 16, the air inlet of the ventilator 15 is communicated with the inside of the device camouflage room 13, the air outlet of the ventilator 15 is communicated with the air inlet end of the ventilation pipe 2 of the vortex elimination tee 1, and the air outlet end of the ventilation pipe 2 is communicated with the exhaust injection assembly through a pipeline.

[0043] The thermal infrared smoke elimination device in the embodiment is mainly suitable for the thermal infrared camouflage smoke elimination treatment of the power station which is matched with a smoke exhaust tunnel. The smoke eliminator 14 is located in the inside 50 of the tunnel, the ventilator 15 and the vortex elimination tee are located outside 51 of the tunnel, and the device camouflage room 13 shields the ventilator 15 and the vortex elimination tee 1.

In the embodiment, the smoke exhaust tunnel inside connecting pipe 45 is arranged to avoid that the humid air in the tunnel is taken out by the high-temperature smoke gas when the high-temperature smoke gas is discharged in the smoke exhaust tunnel, so that the white mist is generated. The smoke exhaust connecting pipe camouflage layer 47 is arranged on the outer periphery of the smoke exhaust connecting pipe 46 from the outside of the tunnel to the outside of the device camouflage room and maintains a certain distance with the smoke exhaust connecting pipe 46. The smoke exhaust connecting pipe camouflage layer is provided with a ventilation orifice, and the smoke exhaust connecting pipe is ventilated and cooled.
