Water, so, it is possible to ensure sampling gun outer surface.
Sampling gun also includes being set in the heater block 6 of the outer surface of probe tube 14, and heater block 6 is arranged on the He of probe tube 14
Between cooling tube 1, for heating the flue gas in probe tube 14, it is ensured that temperature stabilization when flue gas flows through sampling gun, prevent because of temperature
Mutation causes the formation of flue gas physicochemical change and condensate, will not change the flue gas physical property of sampling gun acquisition, can
Combustion process in real reflection drop tube furnace.
As shown in figure 3, heater block 6 is the heater block sections for docking successively（6A, 6B, 6C and 6D in diagram is
Heater block sections）, to carry out being provided with four sections of heater block sections outside zone heating, probe tube 14 to probe tube 14, often
One heater block sections is the zone of heating for being set in the outer surface of probe tube 14, and will pass through heating probe tube 14 sampling is kept
Temperature constant inside pipe 14, sampling gun also includes being set in the heat preservation component 7 of the outer surface of heater block 6, as shown in figure 3, protecting
Warm part 7 is a heat-insulation layer being set in outside zone of heating, to reduce the heat that cooling tube 1 absorbs zone of heating as far as possible, makes heating
The heat that layer is produced more is transmitted to probe tube 14, and energy saving is cost-effective, and particularly, heat-insulation layer includes heat-preservation cotton,
Manufacturing cost is reduced while being incubated.
Sampling gun also include for monitor in probe tube 14 in the pipe of flue-gas temperature temperature monitoring component 9 and for control plus
The temperature-control units of thermal part sections heating-up temperature, each heater block sections is provided with temperature monitoring component 9 in a pipe, such as
Shown in Fig. 3, interior temperature monitoring component 9 is managed for totally four, to make flue-gas temperature of the probe tube 14 per intrasegmental part keep and drop tube furnace
Interior temperature is identical, and particularly, as depicted in figs. 1 and 2, sampling gun also includes that the in-furnace temperature for monitoring dropper in-furnace temperature is supervised
Part 15 is surveyed, by the temperature data of temperature monitoring component 9 and in-furnace temperature monitoring component 15 in contrast pipe, heater block is controlled
The heating-up temperature of sections, makes the temperature in probe tube 14 identical with the temperature in drop tube furnace, so, it is possible to be better protected from Yin Wen
Degree mutation causes the formation of flue gas physicochemical change and condensate, will not change the flue gas physical property of sampling gun acquisition, energy
Enough combustion processes for more really reflecting in drop tube furnace.Temperature monitoring component 9 and in-furnace temperature monitoring component 15 in pipe
Using temperature sensor, or other means for monitoring the temperature.
Preferably, cooling tube 1 includes interior cooling tube 5 and outer cooling tube 4, and external enwergy cooling tube 1 is set in the appearance of interior cooling tube 5
Face, also, interior cooling tube 5 is connected with outer cooling tube 4 in the end that probe tube 14 stretches into drop tube furnace, makes inside and outside cooling tube 4

Sampling gun arranges inside and outside two-layer cooling tube 1 away from the end of drop tube furnace, can increase film-cooled heat, improves heat exchanger effectiveness, energy
The temperature of enough preferably control sampling gun outer surfaces, preferably protects sampling gun to protect it from high temperature failure.
The port of water inlet or the water outlet of interior cooling tube 5 is the entrance of the recirculated cooling water of cooling tube 1, as shown in Fig. 2 now,
Recirculated cooling water is introduced into interior cooling tube 5, and the end for stretching into drop tube furnace in probe tube 14 flows into outer cooling tube 4, from outer cold
But the port of pipe 4 is flowed out.
Or, it is different from the entrance of the port as the recirculated cooling water of cooling tube 1 of above-mentioned interior cooling tube 5, it is also possible to will be outer
Used as the entrance of the recirculated cooling water of cooling tube 1, as shown in figure 1, now, recirculated cooling water is introduced into outer cold for the port of cooling tube 4
But pipe 4, and the end for stretching into drop tube furnace in probe tube 14 flow in cooling tube 5, flow out from the port of interior cooling tube 5, compare
In such scheme, recirculated cooling water flows to interior cooling tube 5 by outer cooling tube 4, and recirculated cooling water absorbs a part in outer cooling tube 4
From drop tube furnace heat and temperature is slightly raised, when the recirculated cooling water after temperature is somewhat raised flow to interior cooling tube 5, inhale
Receiving the heat of heater block 6 will be reduced, and the heat that zone of heating is produced can be made more to transmit to probe tube 14, save energy
Source, it is cost-effective.
All any modification, equivalent and improvement made within spirit of the present utility model and principle etc., all should wrap
It is contained within protection domain of the present utility model.
