The present invention relates to methods for hindering formation of tobacco-specific nitrosamines during processing of dark fire tobacco, as well as a facility in which at least portions of these methods may be conducted. According to the present invention, dark fire tobacco that has been harvested and that is generally green and/or yellow is exposed to an uncontrolled, yet active, ambient airflow so as to provide a substantially aerobic environment about the tobacco. This exposure of the dark fire tobacco to the ambient airflow may be done until the tobacco is substantially brown and/or substantially free of enzymatic activity. Subsequently, the tobacco is exposed to gaseous emissions (e.g., smoke) from combusting sawdust/wood. This step may be conducted at least until the tobacco exhibits a moisture content of no more than about 16% and/or until the tobacco exhibits a gloss or shine on a surface of the tobacco.

The invention relates to a hybrid driving system, which comprises an internal-combustion engine, a first motor, a second motor, a power output shaft used for outputting power, a first brake, a second brake, a first transmission mechanism, and a second transmission mechanism. Two connected transmission mechanisms and brakes are arranged in the hybrid driving system. When the two brakes respectively brake, the two transmission mechanisms are in two different connection modes, namely two different transmission ratios (tap positions) are formed, therefore various working modes and corresponding tap positions can be selected according to different driving conditions of a vehicle, and driving requirements of the vehicle under different working conditions can be met further. Besides, by the adoption of the hybrid driving system provided by the invention, the low-speed torsion of the whole vehicle can be increased and the starting is quickened, moreover, the highest efficiency of the internal-combustion engine can be exerted under a high-speed condition, thereby promoting energy conversion efficiency, reducing tail gas emission and energy loss, and finally achieving the effects of low emission, low fuel consumption and high kinetic energy of the whole vehicle.

The invention relates to a method for recovering oil gas and a device. A combined technology that frozen brine is directly condensed-adsorbed/desorbed to regenerate is adopted to recover the oil gas; and in a direct condensation part, low-temperature brine and collected oil gas are adopted to be directly mixed with oil gas at the condensation part. The method and the device, provided by the invention, have the characteristics of large operating flexibility, low energy consumption, small investment, no potential safety hazard, reach ability in tail gas emission standards, and the like, and can be applicable to the loading/unloading of oil products for vehicles and ships and the oil gas recovery in circumstances, such as oil tank breathing, and the like.

The invention discloses an automobile tail gas emission pretreatment device capable of purifying flue gas. The automobile tail gas emission pretreatment device capable of purifying the flue gas comprises a device shell, a device main body, a motor, a rotating shaft and a heat pump. A support rod is fixedly mounted at the bottom of the device shell. The bottom of the support rod is fixedly installed above a base. The device main body is connected to the interior of the device shell through a damping spring. The motor is fixedly mounted at the top end of the right side of the device main body. The rotating shaft connected with the top end of the motor is arranged in the device main body. A bidirectional screw rod is arranged in the middle of the rotating shaft. A limiting plate and a porousceramic carrier are further arranged outside the rotating shaft. A moving plate is connected to the outer portion of the bidirectional screw rod in a threaded mode. A dredging rod is connected to theoutside of the moving plate. According to the automobile tail gas emission pretreatment device capable of purifying the flue gas, the shock absorbing and heat dissipation work can be conveniently completed in the use process, meanwhile, the noise generated in the working process of the whole device is very small, and the outside environment is not affected.
