Grain, in permanent use process, be easy to cause the blocking of whole equipment, so needing to pre-process flue gas, removes flue gas
In the solid particle that contains.
Meanwhile under normal circumstances, gas analyzer, flue gas pretreatment unit are being analyzed in room (in monitoring room), and cigarette
The sampled point of gas should be located on chimney or flue by professional standard regulation, sampling probe with a distance from analysis room farther out, in flue gas
Steam be easy to liquefy in transmission process, the mixture of water and flue dust can block gas pipeline.In addition, some gases can be dissolved in
In water, detection data and real data is caused not to be inconsistent.Therefore flue gas sampler need itself to have heating and thermal insulation, it is dust-proof,
Anti-blocking function.
Summary of the invention
The smoke collecting device that the object of the present invention is to provide a kind of with heating and thermal insulation, dust-proof, anti-blocking.
The technical scheme adopted by the invention is that: a kind of smoke collecting device, including shell, sampling probe, air inlet pipe, mistake
Filter, the shell is interior to be equipped with shell chamber, and the shell is intracavitary to be equipped with the separation that shell chamber is separated into sampling probe room and filter chamber
Baffle, the sampling probe are located at sampling probe room, and the filter is located at the filter chamber；
One end of the air inlet pipe communicates after passing through shell with filter chamber, and the other end and sampled point connect, the sampling
The air inlet of probe is communicated with the gas outlet of filter, and the sampling probe gas outlet is used for equipped with connecting leg and detector
Connect.
It advanced optimizes, the shell is equipped with maintenance door, the tail end of the maintenance door face filter, the maintenance door
It is connect with casing bolts.
It advanced optimizes, the filter chamber is equipped with heating module, and the heating module includes several heating units, temperature
Sensor, several heating units are located at around filter.
It advanced optimizes, the filter inner wall is equipped with back blow port, and the back blow port is connected to one end of anti-blowpipe, described
The other end of anti-blowpipe is communicated with the air outlet of air-heater.
It advanced optimizes, is connected between the sampling probe and filter by communicating pipe, the communicating pipe is equipped with electricity
Magnet valve.
It advanced optimizes, is equipped with heat traced pipeline for the flue gas in connecting leg along pipeline in the pipe of the connecting leg.
It advanced optimizes, the connecting leg outer wall is coated with the first insulating layer.
It advanced optimizes, the outside of the shell is coated with the second insulating layer.
Beneficial effects of the present invention: the present invention, will be in flue gas by setting filter before flue gas enters sampling probe
Flue dust go out, avoid flue dust from entering sampling apparatus, cause the blocking of equipment, influence the normal operation of equipment, influence equipment
Sampling apparatus and filter are arranged in shell service life, it is possible to reduce the loss of heat in flue gas, therefore reducing is to add
Hot fume and increased energy loss mixs after avoiding the reduction because of flue-gas temperature that steam is caused to liquefy with flue dust, blocking gas transmission
Pipeline.
Detailed description of the invention
The present invention is further described with embodiment with reference to the accompanying drawing.
The structural schematic diagram of Fig. 1 the present embodiment.
Specific embodiment
Smoke collecting device as shown in Figure 1, including shell 1, sampling probe 2, air inlet pipe 3, filter 4, the shell
Interior to be equipped with shell chamber, the shell is intracavitary equipped with the separation baffles that shell chamber is separated into sampling probe room 11 and filter chamber 12, described
Sampling probe 2 is located at sampling probe room 11, and the filter 4 is located at the filter chamber 12；
One end of the air inlet pipe 3 is communicated with filter chamber 12 by communicating pipe after passing through shell 1, the other end and sampled point
It communicates, the air inlet of the sampling probe 2 is communicated with the gas outlet of filter 4, and 2 gas outlet of sampling probe is equipped with connecting leg 5
For connecting with detector.
Flue gas in flue enters filter room 12 by air inlet pipe 3, by filter 4 by the filtrating smoke dust in flue gas
Clean flue gas is sent into for sampling probe 2 afterwards, then flue gas is sent by detector analysis detection by connecting leg 5.
Maintenance door 6, the tail end of the 6 face filter 4 of maintenance door, the maintenance door 6 and shell 1 are equipped on shell 1
It is bolted.When needing replacing filter 4, maintenance door 6 is opened, is replaced after filter 4 is taken out, can simplify maintenance mans
Sequence.
It is equipped with heating module in filter chamber 12, the heating module includes several heating units 71, temperature sensor 72,
