Gas can not enter back into sampler and be sampled pipe and be sampled detection, it is therefore desirable to manually be filled after each sampling to sampling
It sets internal structure and carries out scavenging conduit processing, in case flyash is solidified in sample tap.
Utility model content
The main purpose of the utility model is to propose that furnace pressure sampler a kind of simple in structure and safe and reliable is protected
Warm mechanism, it is intended to ensure furnace pressure sampling and measuring accuracy and the working strength that reduction manually purges.
To achieve the above object, the utility model proposes a kind of furnace pressure sampler heat preservation mechanism, including with stove
The sampler main body tube led to inside thorax, the sampler main body tube other end lead to probe tube and scavenging conduit respectively;
The sampler main body tube outer surface is covered with insulating layer.
Preferably, the insulating layer is internally provided with heatable electric-heating belt and is heated to the sampler main body tube, institute
It states electric-heating belt with power supply to be connected, several temperature sensors is additionally provided with inside the insulating layer, temperature is carried out to the electric-heating belt
Degree detection, the temperature sensor are connected with master controller respectively, and the master controller is also connected with the power supply.
Preferably, the electric-heating belt is wound in the sampler main body tube peripheral surface in the shape of a spiral.
Preferably, the master controller is PLC control circuits.
Technical solutions of the utility model have the following advantages compared with the prior art:
Technical solutions of the utility model are covered with insulating layer by the peripheral surface of sampler main body tube and pass through electric tracing
With heating up so that sampler main body tube is maintained within the temperature range of vapor can not generate condensation, to avoid entrance
Vapor inside sampler main body tube occurs condensation and mixes and stirs solidification with flyash and be blocked in sample tap influence to height
The normal detection of warm flue gas, while pressure in the burner hearth can be avoided to measure risk that is inaccurate and causing unit tripping, reduction pair
Furnace pressure measures sampler and needs regular purge number to reduce working strength.

The utility model proposes a kind of furnace pressure sampler heat preservation mechanisms.
Fig. 1 is referred to, the furnace pressure sampler heat preservation mechanism of the utility model embodiment includes in one end and burner hearth
The sampler main body tube 5 that portion leads to, 5 other end of sampler main body tube then lead to probe tube 7 and scavenging conduit 1 respectively.Its
5 outer surface of sampler main body tube of middle the present embodiment is covered with insulating layer 2.
In order to further increase the guarantor of the furnace pressure sampler heat preservation mechanism in sampler main body tube 5 of the present embodiment
Temp effect, the present embodiment heat sampler main body tube 5 by being internally provided with heatable electric-heating belt 4 in insulating layer 2, electricity
