Abstract
Flying dust sampler automatic purge device. Fly ash sampler function singleness, after live time has been of a specified duration because the ash sample adsorbs gradually on the pipe wall and leads to the jam of sampling tube, can not get the ash sample after blockking up, need pull down equipment and ash removal, waste time and energy. The utility model discloses the constitution includes: sampling tube (2) and fixing three sample nozzle (1) of sampling tube lower part, sampling tube right-hand member and cyclone dust collector (9) intercommunication, cyclone dust collector lower part install and receive grey bottle (10), cyclone dust collector upper portion install injection pipe (5), sampling tube upper portion and blowback sweep pipe (3) and communicate through a set of connecting pipe (4), the blowback sweep the pipe right-hand member and fix on mounting panel (6) and communicate with trachea (7). The utility model is used for flying dust sampler sweeps automatically.
Description
The technical field is as follows:
the utility model relates to a flying dust sampler sweeps device automatically.
Background art:
the carbon content of the fly ash of the boiler is an important index for reflecting the combustion efficiency of a coal-fired boiler of a thermal power plant, and the detection of the carbon content of the fly ash is beneficial to guiding the operation to correctly adjust the air-coal ratio and improving the combustion control level of the boiler; reasonably controlling the carbon content index of the fly ash, being beneficial to reducing the power generation cost and improving the economical efficiency of the unit operation. With the continuous development of electric generating sets with large capacity and high parameters in China, the online detection of the carbon content in the boiler fly ash is realized to control and optimize the boiler combustion, reduce the power generation coal consumption, improve the price competition on-line capability and the comprehensive utilization capability of the fly ash;
fly ash sampler function singleness, after live time has been of a specified duration because the ash sample adsorbs gradually on the pipe wall and leads to the jam of sampling tube, can not get the ash sample after blockking up, need pull down equipment and ash removal, waste time and energy.
The utility model has the following contents:
the utility model aims at solving the problem that present flying dust sampler ash sample adsorbs gradually on the pipe wall and leads to the jam of sampling tube, can not get the ash sample after blockking up, provides one kind and can carry out the blowback, prevents the flying dust sampler automatic purging device that blocks up.
The above purpose is realized by the following technical scheme:
an automatic purging device for a fly ash sampler comprises: the sampling tube with fix the three sample nozzle of sampling tube lower part, the sampling tube right-hand member communicate with cyclone collector, cyclone collector lower part install and receive the ash bottle, cyclone collector upper portion install the injection pipe, sampling tube upper portion and blowback sweep the pipe and communicate through a set of connecting pipe, the blowback sweep the pipe right-hand member fix on the mounting panel and communicate with the trachea.
The flying dust sampler automatic purging device is characterized in that a valve is arranged on the air pipe.
Has the advantages that:
1. the utility model discloses set up anti-purging pipe and be linked together with the sampling tube, draw the air supply of the same kind by the outside and sweep the pipe through trachea to blowback, equipment begins the sample when the valve is closed, opens the valve after the sample and carries out the blowback to whole return circuit promptly to reach and prevent stifled function.
The utility model discloses the installation is dismantled conveniently, and a large amount of manpowers and time can be practiced thrift in the easy access.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1. a sampling nozzle; 2. a sampling tube; 3. a back purge tube; 4. a connecting pipe; 5. an injection pipe; 6. mounting a plate; 7. an air tube; 8. a valve; 9. a cyclone dust collector; 10. an ash collecting bottle.
The specific implementation mode is as follows:
example 1:
an automatic purging device for a fly ash sampler comprises: sampling tube 2 with fix three sample nozzle 1 of sampling tube lower part, sampling tube right-hand member and cyclone collector 9 intercommunication, cyclone collector lower part install and receive ash bottle 10, the cyclone collector lower part has a dirt hole, dust bottle threaded connection is in dirt hole department, cyclone collector upper portion install injection pipe 5, sampling tube upper portion and anti-purging pipe 3 through 4 intercommunications of a set of connecting pipes, the pipe welding is swept with the blowback to the one end of connecting pipe, the other end and sampling tube welding, the blowback sweep the pipe right-hand member fix on mounting panel 6 and communicate with trachea 7, the blowback sweep the pipe right-hand member and trachea and pass through clamp connection.
Example 2:
according to the automatic blowing device of the fly ash sampler in the embodiment 1, the air pipe is provided with a valve 8.
The working principle of the fly ash sampler is as follows: the fly ash sampler is an unpowered self-drawing structure, can automatically track the change of the flow velocity of a boiler flue and keep a constant-speed sampling state, the arrow direction in the figure is the flow direction of flue gas, the flue gas enters a sampling pipe and a cyclone dust collector through a sampling nozzle, dust in the flue gas enters an ash collecting bottle through the cyclone of the cyclone dust collector, and the flue gas passing through the cyclone enters an injection pipe and returns to the flue.
The automatic purging principle of the device is as follows: the valve is closed when sampling, and the valve is opened after sampling, and during external air source entered into the blowback pipe through the trachea, the gas in the blowback pipe entered into the sampling tube through the connecting pipe, then discharged from the sampling nozzle, realizes the blowback.
Claims (2)
1. An automatic purging device for a fly ash sampler comprises: the sampling tube with fix the three sample mouth of sampling tube lower part, characterized by: the sampling tube right-hand member communicate with cyclone collector, cyclone collector lower part install and receive the ash bottle, cyclone collector upper portion install the injection pipe, sampling tube upper portion and blowback sweep the pipe and communicate through a set of connecting pipe, the blowback sweep the pipe right-hand member fix on the mounting panel and communicate with the trachea.
2. An automatic purging device for a fly ash sampler according to claim 1, wherein: the air pipe is provided with a valve.
