How does equipment of organic off-gas treatment have anticorrosive job

Corrode to dust catcher of off-gas treatment equipment it is one of common problems, its reason is, in off-gas treatment the attaint of the off-gas treatment facility that a few belts create when mordant flue gas, the main reason that generation of off-gas treatment equipment corrodes has hydrolysis, oxidation, acerbity, alkaline corrode. So should how has been ability done remove dust does the anticorrosion of equipment work? Environmental protection manufacturer introduces in detail for you.

　 Off-gas treatment equipmentHow anticorrosive:

1, design of off-gas treatment equipment, anticorrosive step takes when making:

In processing a few gas that contain flue gas character are mixed e.g. SO2 when H2O, should take corresponding antirust step, eliminate rubiginous level accordingly e.g. what when besmear is installed, should achieve, and the choice of lacquer of priming paint, face should accomplish standard line above, air temperature spends the tall smoke that the likelihood when cutting the quality that should ensure construction process is medium to because the heat-resisting grade of lacquer wants to be more than off-gas treatment,assure; appears, the coating invalidation that because temperature is exorbitant,accordingly need avoids and brings about.

2, those who enhance a system is sealed:

The main principle of this method is to depend on, what itself of off-gas treatment equipment reachs the equipment in its system and conduit is sealed. Depended on as a result of density of itself of off-gas treatment equipment housing hardness, because this wants,let housing maintain good sealing to must assure the quality that make and installs. The join that and the housing of off-gas treatment equipment is designed arrives should have been done solder of door periphery sealed also should adopt heat-resisting silicon balata.

3, reduce aeriform amount of water contained:

(The dew point temperature that 1) drops aeriform amount of water contained to be able to lower gas and the temperature that raises gas as far as possible even, the difference in temperature that lets aeriform temperature and dew point temperature increases. Practice proved this experience value slants small, because condition of a lot of operating mode is,predict hard.

(2) e.g. the furnace of a few kiln off-gas treatment device that wears a system to use with coal, must have done comprehensive outside heat preservation, do not leave snake in the grass for knot dew, manufacturing operation should ensure exercise temperature compares above of ℃ of dew point tall 20~30 to prevent burnt bag already, prevent a knot again dew is rustily.

4, lower rate of dust catcher air leak:

Air leak also is the main reason that dust catcher corrodes, closely related the negative pressure because of air leak and dust catcher interior, when bigger air leak will jump over negative pressure to add serious; and controlling operation, won’t bring adverse effect to dust catcher function, but the interior that because dust is compared,enters off-gas treatment facility easily because this must the improvement of the sealed structure with good team. Such fan tatty ability won’t be so apparent.
