Embodiment

[0053] The manufacturing process of the present embodiment heater is as follows:

[0054] Sectional diagram of the heater figure 1 Shown, this heater 1 is made of mica 13 and heating wire 12 and stainless steel sheet 11.

[0055] A stainless steel shell with a flatness of 0.5 mm is processed and manufactured as the stainless steel outer cladding of the heater 1 .

[0056] Wrap the heating wire 12 covered with a glass fiber insulating tube evenly on the mica sheet, and after the mica sheet is covered with the heating wire 12, fix the two free ends of the heating wire 12.

[0057] Put the mica sheet 13 wrapped with the heating wire 12 into the stainless steel shell 11, lead out the power supply cable, bend, close and rivet the connecting edge of the stainless steel shell.

[0058] Mounting holes are opened on the heater 1 packaged with stainless steel.

Abstract

The invention relates to a Fourier infrared spectrometer, a sample pool, a heater and a making method thereof. The heater comprises a metal shell, an electric heating wire and an insulator inner core. The metal shell is made from corrosion-resistant metal. The insulator inner core is made from an insulator having thermo-chemical stability of more than 500 degrees Celsius. The insulator inner core is wound with the electric heating wire, and wire bodies of the wound electric heating wire are kept insulated from the insulator inner core. The metal shell is encapsulated outside the insulator and the electric heating wire, and wiring cables connected with two ends of the electric heating wire are led out of the metal shell. The Fourier infrared spectrometer, the sample pool, the heater and the making method thereof overcome the defects of thermo-chemical stability of the heater and volatile matter possibly producing interference to measured gas in the prior art and the defect of unstable connection between the heater and the sample pool.

Description

technical field [0001] The present invention generally relates to a Fourier transform infrared spectrometer, in particular to a Fourier transform infrared spectrometer, a sample pool, a heater and a manufacturing method thereof. Background technique [0002] With the rapid development of the economy, the types of pollution sources are increasing, especially in chemical industry areas, industrial concentration areas and surrounding environments. The pollution methods and ecological damage types are becoming more and more complex, the environmental pollution load is gradually increasing, and environmental pollution accidents occur from time to time. At the same time, as the public's environmental awareness gradually increases, various types of environmental pollution complaints and disputes are becoming more and more frequent, so the types and requirements for environmental monitoring are getting higher and higher. [0003] According to the national environmental protection pl...
