Background technology
Conduction oil smoke discharge amount is few, no blowdown pollution, belongs to environmental protection organic heat carrier.Due to, the advantages of its thermal efficiency is high, homogeneous heating is stable, safety is good, comprehensive benefit is high, in the industrial production using more, belonging to safety heat-preserving material.
The semi-finished product alkyd resin of lead red alcohol acid antirust paint peculiar to vessel needs the characteristic processing such as safe and stable using conduction oil, ensures, with this, the quality painted.There is more requirement to the control of temperature during processing alkyd resin, temperature need to reach 160 DEG C and keep 15min to add material to carry out polyreaction, after continue to be heated to 180 DEG C and add new material to keep 30min to carry out alcoholization reaction, finally need for temperature control at 210 DEG C and to keep about 5h it is allowed to temperature error within 5 DEG C.During use, conduction oil first heats in stove, delivers to the reactor in distant place paint process workshop under the power that hot oil pump provides by conduit, to material of paint (alkyd resin) heating in reactor.
Main by the investigation of factory with check pertinent literature, showing that conduction oil temperature control mainly has following two forms:A kind of is scene formula on duty more typically, provides heat to conduction oil by the way of burning coal, right
The control of temperature is mainly directly observed thermometric instrument by live operator on duty and is controlled the size of the amount of delivering coal and the unlatching of induced-draught fan, thus controlling heat conduction oil temperature；Which automaticity is low, and temperature adjustment error is big, and dynamic response is slower, and labor intensity is big, and industrial accident easily in work under bad environment (during summer, operating ambient temperature is up to 50 DEG C).Second is the PLC control method based on bus, in electrically heated mode to heat-conducting oil heating, the data that temperature sensor detects is sent to control room using fieldbus by this mode, scene is automatically controlled according to the data that transmission comes by control room main frame (PLC), thus controlling the temperature of conduction oil in stove.This kind of control mode has the advantages that high degree of automation, dynamic response are good, and scene does not need operator on duty, greatly reduces labor intensity and the industrial accident incidence rate of operator, but equipment totle drilling cost is higher, needs laying-out more.
