Description
Technical field
The utility model relates to a kind of gas pre-service, especially a kind of gas pretreatment device that is applied in the analytical instrument.
Background technology
In gas monitoring system, because the gas componant more complicated, when the specific gas composition was monitored, other impurity can exert an influence to measurement result.For clean, dry gas is provided to analyser, generally gas is carried out pre-service in use or before measuring.
General sample gas all has high dust, saturated moisture content, easily hardens and is rich in SO
2, NO
X, CO, H
2Characteristics such as burn into crystallization gas such as S, sample temperature degree, pressure surge are also bigger.Therefore, pretreatment unit is being born the effect with sample gas dust-filtering, pressure adjustment, temperature constant, and the sample gas after the processing just can offer analysis meter and use.
Existing gas pretreatment device all adopts filtering element to come sample gas is carried out dedusting, dewaters, but growth along with service time, phenomenons such as water-vapo(u)r saturation or dust obstruction can appear in pretreatment unit, cause continuing treatment samples gas, have hindered further carrying out of gas analysis.
In order to solve the problems of the technologies described above, present solution is: as shown in Figure 1, in gas pretreatment device, increase the blowback module, and be set fixing blowback interval time, and after processing unit work a period of time, valve-off 11, open valve 12, in treatment channel, feed purge gas, thereby steam on the filtering element or dust are oppositely purged away, to realize the regeneration of processing unit.
Increase blowing function and can make processing unit be back to duty again, but also have the following disadvantages:
1, gas processing is discontinuous
Only adopt a processing unit, also i.e. one tunnel treatment channel when processing unit lost efficacy, feeds the regeneration of blowback air physical efficiency realization processing unit, but the processing of sample gas will interrupt, thereby causes the interruption of follow-up gas analysis.
2, fix the time interval of blowback, can occur following two kinds of situations like this:
1) processing unit did not also lose efficacy, and in the time of still handling sample gas, just fed blowback air, and it is more frequent to cause sample gas disposal process to be interrupted like this, and then situation is more obvious off and on to make the gas analysis process, is unfavorable for gas-monitoring;
2) processing unit lost efficacy, but fed blowback air not yet, and the sample gas that causes entering gas analyzer does not meet standard, and follow-up detection is brought very big influence.
