Problems solved by technology
Although the sampling probe can continuously sample online, but because it is cooled by water, it needs to configure the water source on site, and it also needs to purify the cooling water, so the operating cost is very high

Embodiment Construction
[0031] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific drawings.
[0032] See figure 1 The sampling probe of the present invention includes a sample gas cleaning chamber 100, a sampling tube 200, and a recoil tube 300. The sample gas cleaning chamber 100 is composed of a connecting plate 110, a buffer tube 120, an outer flange 130 and a filter element support plate 140. The connecting plate 110 and the outer flange 130 are welded to both ends of the buffer tube 120, and the filter element support plate 140 is provided with fasteners. Installed on the outer flange 130, the connecting plate 110 and the filter element support plate 140 seal both ends of the buffer tube 120, so that the internal space of the buffer tube 120 forms a sample gas cleaning chamber 100. See Image 6 with Figure 7 In order to improve the sealing eff...

Abstract
The invention discloses a sampling probe which comprises a sample gas cleaning chamber, a filter and a sampling pipe, wherein the sample gas cleaning chamber is provided with a sampling pipe access mouth and a sample gas outlet; the filter is installed at the inlet end of the sample gas outlet and is located in the sample gas cleaning chamber; the sampling pipe is installed on the sampling pipe access mouth in the sample gas cleaning chamber and inserted in a rotary kiln tail smoke chamber, an air cooling jacket is installed on the sampling pipe, and the outer jacket face of one section of the air cooling jacket inserted into the rotary kiln tail smoke chamber is coated with a heat insulating layer capable of resisting high temperature more than 1100 DEG C. The invention solves the cooling problem of the sampling pipe by coating the sampling pipe with the heat insulating layer and combining air cooling, and cost is reduced without investing in building a water supply device. The invention can effectively clean particles in the sample gas cleaning chamber and the sampling pipe and blow the particles back to the kiln by arranging two modes of internal back blowing and external back blowing, and no new waste water and waste gas treatment equipment is used without pollute environment.
Description
Technical field [0001] The invention relates to a sampling probe used in a high-temperature flue gas analysis system. Background technique [0002] The production enterprises in the cement industry have always had the characteristics of high energy consumption and high pollution due to the particularity of their production. As the country pays more and more attention to environmental protection and energy saving, they are now paying attention to the energy consumption and pollutant emissions of each newly built or expanded cement plant. All have put forward strict requirements. Enterprises with high energy consumption and substandard emissions must be resolutely shut down for rectification, which presents new opportunities for the development of my country's high-temperature flue gas analysis system. The high-temperature flue gas analysis system analyzes the high-temperature gas composition in the tail gas chamber of the cement rotary kiln, and guides cement manufacturers to chang...
