An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery is continuously recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and provides the electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

The invention discloses a gas chromatography detector, which comprises components such as a heating block, a gas pipe, a reference filler, a temperature measuring element, a catalyst filler, a heat insulating layer, a cavity, and a signal processing system. Using air as the carrier gas and make-up gas, the effluent of the chromatographic system is driven by the carrier gas to quickly pass through the reference packing and the catalyst packing in sequence. The catalytic combustion of the effluent releases heat to increase the temperature of the catalyst packing, and the temperature change is converted by the temperature measuring element. output as an electrical signal. The detector can be used to construct a general-purpose detector or a selective detector by changing the chemical properties of the catalyst filler. The detector has the characteristics of high sensitivity and fast response, and can be used for the detection of volatile organic compounds and combustible inorganic gases.

The invention relates to the technical field of a nanometer material and provides a self-cleaning fluidized bed reactor for carbon nanotube production. The self-cleaning fluidized bed reactor comprises a fluidized bed reactor body with a reaction chamber and a rotating device arranged in the reaction chamber, wherein the rotating device comprises a rotating shaft and a rotator; the rotating shaft is longitudinally arranged along the center of the reaction chamber; the rotator is connected with the rotating shaft and is rotated under the driving of the rotating shaft; the reaction chamber is provided with a flow inlet and a flow outlet; the gas flows in through the flow inlet and flows out through the flow outlet; the rotating shaft is communicated with the flow inlet; the rotator is communicated with the rotating shaft; a plurality of gas holes are formed on the rotator; the gas holes are opposite to the inner wall of the reaction chamber and are communicated with the rotating shaft; gas flows out through the gas holes. In the self-cleaning fluidized bed reactor for carbon nanotube production, the rotator is rotated under the driving of the back-flushing acting force of the gas flow; when the rotator is rotated, the catalyst and the carbon nanotube adhered to the inner wall of the reaction chamber are cleaned by the rotator; the inner wall of the reaction chamber is washed by the gas sprayed from the gas holes; the carbon nanotube is prevented from being locally accumulated on the inner wall of the reaction chamber and accordingly causing the reduction of effective volume in the fluidized bed.
