It high-volume need to strictly be monitored by environmental protection administration with discharge gas ingredient, the parameters such as type, concentration, total amount of discharged flue gas need to pass through
Various flue gas analysis systematic surveys obtain.But the flue gas of direct emission usually contains a large amount of dust, moisture etc., it can be to measuring instrument
Device causes the damages such as burn into blocking, therefore needs using pretreatment unit before being detected using measuring instrument to discharge cigarette
Gas is pre-processed, and pretreatment unit mainly includes air inlet pipe and condensation de-watering apparatus, is equipped with net or ceramic filtering in air inlet pipe
Core is dusted, and condensation de-watering apparatus includes condensate, electronic refrigerating sheet and radiator, by condensation de-watering apparatus vaporous water
Divide and is condensed into liquid and is discharged.
Flue Gas Pretreatment Device in the prior art has the following problems:
1, condensation water removal effect it is bad: due to condensation de-watering apparatus condensation path length it is limited, can not effective cooled flue gas,
Cause Water vapor condensation insufficient；Since gas outlet position is arranged unreasonable, flue gas is easy to carry about with one condensed water in discharge process.
2, condensed water dissolves ease of solubility sour gas: containing a large amount of acidic materials, such as SO in flue gas2、NO、NO2Deng,
De-watering apparatus removal process can there is a situation where sour gas soluble easily in water to be pulled away together with water in condensation for pollution sources flue gas,
Cause SO2、NO2Etc. gas components loss, influence the accuracy of gas concentration and total amount final detection result.As environmental protection is arranged
It is further stringent to put standard, pollution sources object concentration of emission is lower and lower, and detection difficulty increases, and the loss of component is for result precision
Influence become serious.Inhibiting soluble acidic gas by acid adding is currently used method, but its acid bottle for storing up sour device
Disassembly and formic acid are inconvenient；Acid bottle is only capable of placing vertically, and the Flue Gas Pretreatment Device for being equipped with the sour device of storage is caused to be only capable of using
In level sampling, cannot obliquely or vertically sample.
3, flue gas condensing only relies on heat exchange cooling in condensation de-watering apparatus, lacks precooling module.
Utility model content
