How equipment of off-gas treatment of organic and organic industry is anticorrosive reach design principle

Corrode to dust catcher of equipment of organic industry off-gas treatment it is one of common problems, its reason is, in organic industry off-gas treatment the attaint of the facility of organic industry off-gas treatment that a few belts create when mordant flue gas, the main reason that generation of equipment of organic industry off-gas treatment 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.

　　One, how equipment of organic industry off-gas treatment is anticorrosive:

1, design of equipment of organic industry off-gas treatment, 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 organic industry 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, those who have the equipment in itself of equipment of machine industry off-gas treatment and its system and conduit is sealed. Because have density of itself of equipment of machine industry off-gas treatment,depended on housing hardness, because this wants,let housing maintain good sealing to must assure the quality that make and installs. And have the link that the housing of equipment of machine industry off-gas treatment designs should have 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 body 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 device of furnace of a few kiln organic industry off-gas treatment 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 facility of organic industry off-gas treatment easily because this must the improvement of the sealed structure with good team. Such fan tatty ability won’t be so apparent.

　　2, the design principle of equipment of organic industry off-gas treatment:

1, safe principle:

A lot of moment use equipment of organic industry off-gas treatment to handle organic waste gas, and organic waste gas is combustible normally explode easily, poisonous and harmful gas, what in the design so time of equipment of organic industry off-gas treatment wants to consider above all is safe principle. Be in especially chemical industry, this problem is attached most importance to especially should, for instance the chroma safety index of volatile organic matter must is worth in 1/4 of lower explosion limit move below.

2, environmental protection principle:

Main purpose uses equipment of organic industry off-gas treatment to handle waste gas to absorb namely, the component of organic waste gas that normally the enterprise discharges is various, so equipment of organic industry off-gas treatment must achieve environmental protection to purify a requirement.

3, reliable principle:

Electronic-controlled reach the information system that accusing oneself is equipment of organic industry off-gas treatment to handle core, so electronic-controlled principle design wants concise and reliable, electric component also wants on the safe side. Electronic-controlled the part should want to have favorable working environment, deploy explosion proof to control ark normally. The dependability that controls a system also is one of safety.
