Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] like figure 1 and figure 2 As shown, the servo motor 1 in the present invention is fixed on the upper end steel plate of the base 32 through the speed reducer 2 through the fixed sleeve 3, and the speed reducer 2 is connected with one end of the ball screw 33 through a shaft coupling. The end of the screw rod 33 is supported by a bearing, and the bearing is fixed on the upper steel plate of the base 32; the other end of the ball screw 33 is connected to the inside of the piston rod 5 through a ferrule, and the ball nut matched with the ball screw 33 Fixed with the piston rod 5 on the flange. The flange of the piston rod 5 is fixed to the moving block 29 by screws, and the moving block 29 is fixed to the linear guide rail 31 installed on the base 32 . The scale grating of the grating ruler 4 is fixed on the base 32 side, and the reading head of the grating ruler 4...

Abstract

The invention discloses a tail gas automatic collection method and device for self-adjusting the motor speed according to the flow value. The invention comprises a tail gas collection unit, a tail gas generation unit, a tail gas analysis unit, and a tail gas metering unit. The tail gas generation unit enters the tail gas collection unit after passing through the tail gas metering unit. The flow meter in the unit controls the exhaust gas collection unit, so that the air pressure value of the gas storage tank in the exhaust gas collection unit always tends to the set intermediate value. The device of the present invention adopts an automatic control collection method, and controls the rotation amount of the motor through the value displayed by the gas flow meter, so as to achieve the effect of not affecting the combustion of the combustion pool while collecting the tail gas.

Description

technical field [0001] The invention relates to an exhaust gas collection device, in particular to an automatic exhaust gas collection method and device for self-adjusting the motor speed according to the flow value. Background technique [0002] In recent years, the research work on natural gas calorific value measurement has been carried out in many scientific research institutes. Energy measurement reflects the thermal energy of natural gas. As a reasonable and scientific measurement method that can best reflect the characteristics of its fuel, it is used in natural gas trade used widely. [0003] However, volume measurement is still widely used as the basis for natural gas trade settlement in China. my country is still relatively backward in terms of gas calorific value measurement base standards including natural gas, and the existing gas calorific value measurement system cannot meet the rapid development of gas energy. In view of the above status quo, the research a...
