Embodiment Construction

[0024] Some specific embodiments of the present invention will be described in detail below, by way of example and not limitation, with reference to the accompanying drawings. The same reference numbers in the figures designate the same or similar parts or parts. It should be understood by those skilled in the art that the drawings are not necessarily drawn to true scale.

[0025] Please refer to Figure 1 to Figure 6 , the present invention provides a high-temperature reflection sample pool air inlet device, which is installed at the front end of the sample pool of the high-temperature Fourier detection system and is used to transport the gas to be measured into the sample pool. It has constant current, constant pressure and high temperature resistance at the same time. , Corrosion resistance, filter function.

[0026] The high-temperature reflection sample cell air inlet device provided by the present invention is provided with an air inlet pipe 1, a filter cavity 2, a sam...

Abstract

The invention provides a high-temperature multi-reflection sample cell gas inlet device comprising an air inlet pipe, a filter cavity, a sample cell inlet, a sample cell outlet and a vacuum generator.The air inlet pipe is communicated with the filter cavity; the filter cavity is communicated with the sample cell inlet, the detected gas can enter the filter cavity through the gas inlet pipe, the filtered gas enters the sample cell through the sample cell inlet, the sample cell outlet is communicated with the vacuum generator; and the vacuum generator can generate a negative pressure to suck out the gas in the sample cell through the sample cell outlet. The high-temperature multi-reflection sample cell gas inlet device has the characteristics of blockage prevention, easiness in replacementand stable flow; meanwhile, the stability and reliability of the device are guaranteed, the sample cell is protected from being polluted and damaged, and the operation stability of the high-temperature multi-reflection sample cell gas inlet device is improved.

Description

technical field [0001] The invention relates to a high-temperature multi-reflection sample cell air inlet device. Background technique [0002] With the application of high temperature Fourier detection system in waste incineration and hazardous waste treatment, more and more instruments with direct measurement method appear in the market, and the Fourier system put into production by our company is also improving year by year. However, the direct measurement method requires a set of high-temperature air inlet device, which not only needs to stably transport the measured gas into the sample cell, but also has the functions of constant current, constant pressure, corrosion resistance and filtration. Since there is no such device on the market, we decided to develop a device that can be used for high temperature sample cells with gas inlet and outlet on the same side. SUMMARY OF THE INVENTION [0003] The present invention provides an air inlet device for a high temperature...
