Problems solved by technology
This kind of dew point meter series products are used for dew point detection of air, SF6, CO2, N2, H2 and other gases, the detection range is generally only about -40°C to 60°C, and the extension type of the tester based on the chilled mirror principle is the lowest. There are those up to -80°C, but none of them are suitable for the determination of the higher dew point temperature of the flue gas in the solid waste incinerator system

The invention discloses a dew-point temperature measuring instrument for a smoke acid medium of a solid waste incinerator, which comprises a measurement sensing mechanism and a control unit, a device main body, an intake valve and an air input port. The measurement sensing mechanism comprises a thermal-sensitive and humidity-sensitive integrated sensing mechanism, wherein the thermal-sensitive and humidity-sensitive integrated sensing mechanism comprises a main body, a thermal-sensitive and humidity-sensitive integrated sensing sheet, a thermal conductive silicon grease and an end nut; a front surface of the thermal-sensitive and humidity-sensitive integrated sensing sheet located at the top of the thermal-sensitive and humidity-sensitive integrated sensing mechanism is provided with two groups of never intersected gilded lines so as to be used as a humidity-sensitive sensor, and a thermoelectric couple is embedded in the main body so as to be used as a thermal-sensitive sensor; and the air input port orderly passes through the intake valve, an air input channel and an air output channel to be matched and connected with an air output port so as to form a ventilation channel; and the air flowing in the ventilation channel flows through heat exchange fins.
Description
Technical field [0001] The invention relates to a temperature measuring instrument, in particular to a solid waste incinerator flue gas acid medium dew point temperature measuring instrument. Background technique [0002] The flue gas produced by the incineration of solid waste is a mixed flue gas. In addition to containing a large amount of SO2, SO3, HF, HCL, NOx and other acid gases, it also contains a small amount of mercury (Hg), cadmium (Cd), lead (Pd) and its Compounds, and other heavy metals and their compounds. The strong acid condensate produced by this mixed flue gas is more corrosive than the sulfuric acid (H2SO4) condensate produced by general industrial furnace flue gas. Therefore, the dew point temperature of the main parts of the solid waste incinerator flue gas treatment system can be accurately measured, so that the accurate data measured can be used to study and take appropriate countermeasures and measures to minimize and delay the strong corrosive acid dew C...
