[technical field]
The utility model is about a kind of gas-solid two-phase sampling device, refers to a kind of fly ash sampler of boiler flue especially.
[background technology]
, also can be the economical operation analysis simultaneously science data are provided for the boiler combustion adjustment provides feasible foundation for timely and accurately, need carry out sample analysis the boiler flue flying dust.
Yet for a long time, in the sampling process of flying dust, sampler usually can be because of flying dust stops up or flying dust obstructions of lump because of moisture is too high, and making can't operate as normal, makes sampling be difficult to guarantee stable reaching reliably.For this reason, industry proposes with extrinsic motive system to be carried out ash disposal and handles, and normally purge with pressure gas, yet this mode is strong excessively to external power dependence, when external power failure, promptly can't normally purge; And too complexity and cost are higher to rely on extrinsic motive also to make equipment.
[utility model content]
For solving the problem of above-mentioned existence of the prior art, the utility model provides a kind of fly ash sampler, and it is the interior residual dust of scavenge system effectively, and can prevent the flying dust caking, guarantees the sampler stable and reliable operation.
For achieving the above object, the utility model provides a kind of fly ash sampler that is used for boiler flue, comprise sampling gun, separation vessel, collecting the gray bottle, jetting pump and solenoid valve, one end of this sampling gun extend in the flue, the other end links to each other with separation vessel, this separator lower end connects a collection powder bottle, this separation vessel also connects an air intake duct, this air intake duct stage casing is connected with a three-way pipe, an interface of this three-way pipe connects the nozzle of this air intake duct that is positioned at jetting pump, another interface of this three-way pipe connects this solenoid valve, and solenoid valve and outside atmosphere connect.
Also further be provided with in this sampling gun one by a Single-chip Controlling to prevent to fly the well heater of powder caking.
Because adopt technique scheme, the utility model fly ash sampler has following beneficial effect: the utility model fly ash sampler, utilize the extraneous air and the pressure differential of flue gas, total system is purged automatically, remove residual dust, and avoided stifled powder; And well heater can remain on predetermined temperature with temperature in the fly ash sampler, guarantees the flying dust obstruction of not luming, and guaranteed the reliable and stable of fly ash sampler operation.
[description of drawings]
Fig. 1 is the synoptic diagram of the utility model fly ash sampler.
[embodiment]
As shown in Figure 1, the utility model fly ash sampler is used in and carries out Fly ash sampling in the boiler flue, comprises sampling gun 1, separation vessel 2, collecting the gray bottle 3, jetting pump 4 and a solenoid valve 5.
One end of this sampling gun 1 extend in the flue, also is provided with a well heater 11 in this sampling gun 1.Sampling gun 1 in the utility model adopts the abrasion-proof stainless steel manufacturing, and the anticorrosion antiwear performance is good, and is durable in use.
This separation vessel 2 is connected in the end of this sampling gun 1, in addition, this separation vessel 2 also connects an air intake duct 21, these air intake duct 21 ends are connected with a three-way pipe 22, one of them interface of this three-way pipe 22 is connected with a regulator 23, and being connected with a nozzle 24 at the end of regulator 23, these nozzle 24 jet velocities can be regulated by regulator 23.
This collection powder bottle 3 is connected in the lower end of this separation vessel 2 by a rapid-acting coupling 31.
One end of this jetting pump 4 extend in the flue with flue and connects, and its other end can stretch into for the nozzle 24 of air intake duct 21 ends.
This solenoid valve 5 is connected on another interface of three-way pipe 22, and this solenoid valve 5 connects with outside atmosphere.
This fly ash sampler also can further comprise a switch board (scheming not shown), is provided with a single-chip microcomputer in this switch board.This single-chip microcomputer includes the temperature control modules of control heater 11 keyings and the time control module that control electromagnetic valve 5 opens and closes.This switch board further comprises a display screen and some control buttons.In the utility model fly ash sampler course of work, under Single-chip Controlling and have program control purging function and automatically heating prevent nozzle caking function, can avoid system in the flying dust obstruction of luming like this.
In addition, also can in flue, establish the temperature that a thermal detector 6 is monitored the flue gas in the flue, and the data that record are offered switch board, so that the keying of Single-chip Controlling well heater 11.
When the work initialization, solenoid valve 5 is in closed condition, and sampler is in running order; Afterwards, solenoid valve 5 is opened, owing to have draught head in atmosphere and the flue, atmospheric pressure makes outside a large amount of air enter in the system by solenoid valve 5 and purges greater than the air pressure in the flue, purges intrasystem residual dust clean; Then, close solenoid valve 5 and the rapid-acting coupling 31 of opening between collection powder bottle 3 and the separation vessel 2 is normally taken a sample; After the sampling, open solenoid valve 5 once more and system is purged once more, the residual dust in the scavenge system pipeline by the air in the external world.In whole sampling process, the pattern of purging → sampling → purging circulates all the time and carries out, and its time interval is controlled by time control module by single-chip microcomputer, thereby has effectively avoided stifled powder problem.
Simultaneously, the flying dust agglomeration problems of bringing when preventing that exhaust gas temperature is lower than dew point or moisture is too high in flying dust, under the control of the temperature control modules of single-chip microcomputer, the well heater 11 of sampling gun 1 heats automatically, the flying dust temperature that obtains in the sampling gun 1 is remained on predefined temperature, guaranteed that the flying dust drying do not lump.Thereby the flying dust caking that can effectively prevent positions such as sampling gun 1, separation vessel 2 and jetting pump 4 stops up.
Like this, the utility model fly ash sampler utilizes extraneous air that total system is purged automatically, removes residual dust, and has avoided stifled powder; And well heater 11 can remain on predetermined temperature with temperature in the fly ash sampler, guarantees the flying dust obstruction of not luming, and guaranteed the reliable and stable of fly ash sampler operation.
