Problems solved by technology

[0003] Some of the lasers of the existing laser gas analyzers are packaged by the laser itself, and some are also sealed and filled with nitrogen, but because there is no special equipment, nitrogen filling is not necessary completely
At the same time, the cost of special equipment is relatively high

Embodiment Construction

[0010] Such as figure 1 As shown, a nitrogen charging device for a laser gas analyzer includes a closed cavity composed of a launch seat 10, a collimator cylinder 9, a laser collimator 8 and a collimator lens 7. The launch seat 10, the laser The collimator 8 and the collimating lens 7 are fixed inside the collimating cylinder 9, and the collimating lens 7 is placed in front of the laser collimator 8; a laser 4 is fixed on the launching seat 10, The light emitted by the laser 4 is transmitted to the laser collimator 8 through the collimating lens 7; there is a through hole in the center of the launch seat 10, and there is a silicon rubber pad 3 in front of the through hole, which is a transition nut 11 fixedly connected to the launch seat. Pressed in the launch seat 10, there is a screw 2 12 connected to the launch seat 10 through the transition nut 11, a sealing ring 2 2 is placed between the screw 2 12 and the transition nut 11, and the collimation cylinder One side of 9 has...

Abstract

The invention discloses a nitrogen charging device for a laser gas analyzer, which comprises a transmitting seat, an alignment cylinder, a laser aligner and an alignment lens, wherein the transmitting seat and the laser aligner are fixed in the alignment cylinder, and the alignment lens is arranged in the laser aligner and connected with the alignment cylinder to form a closed cavity; a laser device is fixed on the transmitting seat, and light transmitted by the laser device is transmitted onto the laser aligner through the alignment lens; a silicon rubber pad is pressed in the transmitting seat through a transition nut; a screw 2 is connected to the transmitting seat through the transition nut; one side of the alignment cylinder is provided with a threaded hole; and a screw 1 matched with the threaded hole is connected to the alignment cylinder through the threaded hole. A needle tube is penetrated into the silicon rubber pad to charge nitrogen, and the nitrogen substitutes air in the closed cavity. The nitrogen charging device is simple, can charge nitrogen into the closed cavity conveniently and quickly, and has strong operability.

Description

Technical field [0001] The present invention involves a nitrogen -filled device, which is specifically for the nitrogen -filled device for laser gas analyzers. Background technique [0002] The exhaust emissions such as flue gas emissions, chemical industry and other enterprises in power plants cause pollution to the environment, and the emission gas is required and controlled.At present, the principle of the laser gas analyzer is almost the same, that is, after the laser beam enters the sample pool, it is received by the receiver after decaying.Analysis of gas to understand the ingredients and concentrations of the measured gas.Because the air contains a large amount of water and CO 2 The laser is fragile, and water and gas have a great corrosion effect on laser.For measuring H 2 O and CO 2 In the case, the effect of air on the measurement results is also greater. [0003] Some laser analyzers of the existing laser gas analyzer are encapsulated by the laser itself, and some are ...
