Heat conduction oil system special-purpose cleansing agent the heat conduction painter's shop is a heat-carrying agent, started widely to apply in the production heating system. In heating system's heat conduction oil, after long time use, will have a series of physical chemistry change, like rises and so on viscosity, carbon residue, acid value, the system interior will present massive dirt and so on coking, carbonization, to a certain extent will affect system's normal use, will cause the current capacity to reduce, the heating temperature will be insufficient, has had certain influence to enterprise's planned production. heat conduction oil three broad headings: Paraffinss saturated, the aromatic hydrocarbon class and the napthenes. as a result of the present use's heat conduction oil, mainly by saturated paraffinss, the aromatic hydrocarbon class material composition primarily, aromatic hydrocarbon class heat conduction oil, because the coal content's proportion is big, and includes many not saturated duplet bonds, therefore in operating temperature time, easy to have the duplet bond break to have the addition reaction, causes the heat conduction oil member the volume to increase gradually, forms coking; When this coking saves in the system heating pipe wall, also has hindered the heat conduction oil transmission efficiency seriously, causes the pipe wall temperature to be high, causes on pipe wall's coking dark combustion, forms the carbonization; Simultaneously the aromatic hydrocarbon class heat conduction oil easy to oxidize, easy to cause the acid value fast rise; Moreover, in the heat conduction oil system opens the type to store the oil inflation pot easily the air in each impurity pollution, also forms one of dirt reasons. Therefore, paraffinss saturated the heat conduction oil, because its chemical stability is strong, starts to be valued people's. the heat conduction oil system cleaning media uses in various factories production the different trademark heat conduction oil is a heat-carrying agent specially, after using period of time, in the system appears the oil cokes filthy and carbonizes the filthy effective elimination the specialty necessary medicament. It through the force seepage, the peeling and the dissolution, is loose the oily dirt and other mineral substance's deposit peeling and the dissolution, causes it aerosol to discharge in the solution. And may mix in the oily dirt the carbides, the coking pellet cleans together. Guaranteed that removing dirty stuff rate above 98.7%, the equipment does not have any corrosion and the adverse effect in the clean process, by human body security. Has certain rust prevention ability after the special-purpose cleansing agent clean's equipment. [principal constituent] surface active agent, oily dirt stripper, degreaser, passivator, penetrant, conditioner and so on [product characteristic] pH value ≥8, white solid powder, proportion 2.47±0.02, but dissolves rapidly in the peroxide solution. Does not burn, does not explode; Non-toxic, non-corrosion hazardous nature; [use scope] each kind of trademark heat conduction oil, because uses the strict heavy oil class dirt which appears, to carbonize filthily, cokes filthily.after [operating procedure] the entire operation's scavenging period probably is 3~5 days (including dehydration). Invites when the system attendants clean requests to complete the clean process project the historic record.
[after operating procedure] the entire operation's scavenging period probably is 3~5 days (including dehydration). Invites when the system attendants clean requests to complete the clean process project the historic record. clean technical process: Discharges the old oil -> prewashing -> clean -> to add the mesh -> laundering①-> laundering②-> laundering③-> adds fresh oil -> dehydration -> normal operation
(1) discharges the old oil: Using the heating system, the heat conduction oil heating to 70-80℃, before it's too late in the draindown system all heat conduction oil, after the emissions completes, may act according to the condition, blows with the compressed air sweeps the surviving heat conduction oil which in the system has not drained away. (2) prewashing: Will clean the special-purpose medicament after the circulating water total quantity 0.5% measurement dissolution, invests the system in heating system any spot, overbrims the clear water to the system, opens the circulating pump to carry on the circulation, climbs to using the heating furnace the water temperature 60℃±5℃, cuts in system's related valve, enables in system's all spots to obtain the circulation separately. Three hours later, turns on system's all low position wash water valve, in draindown system's water. (3) clean: Will clean the special-purpose medicament after the circulating water total quantity 4.5~5.5% measurement dissolution, invests the system in heating system any spot, and overbrims the clear water after the system, opens the circulating pump to carry on the circulation, uses the heating furnace heating clean medicament to 60℃±5℃. The cut system valve, causes in the system all spots to be possible to obtain the clean, the valve cut carry on one time suitably according to each hour. Entire scavenging period many in 24 hours. (4) adds the mesh: After the clean completes, use system's all low position wash water valve emissions clean solution. And in system's filter, installs 20 goal strainers.
(5) laundering①: Tops up the clear water to the system, opens the circulating pump to carry on the circulation, climbs to using the heating furnace the water temperature 90℃±5℃, cuts in system's related valve, enables in system's all spots to obtain the circulation separately. Carries on the rinse to this system, three hours later, turns on system's all low position wash water valve, in draindown system's water. The demolition system filter, take out the mesh, replaces 40 goal strainers. (6) laundering②: Tops up the clear water again to the system, and opens the circulating pump to carry on the circulation, climbs to using the heating furnace the water temperature 90℃±5℃, cuts in system's related valve, enables in system's all spots to obtain the circulation separately. Carries on the rinse to this system, three hours later, turns on system's all low position wash water valve, in draindown system's water. The demolition system filter, take out the mesh, replaces 60 goal strainers. (7) laundering③: Tops up the clear water to the system, opens the circulating pump to carry on the circulation, climbs to using the heating furnace the water temperature 90℃±5℃, carries on the rinse to this system, three hours later, turns on system's all low position wash water valve, in draindown system's water. After the emissions completes, may act according to the condition, blows with the compressed air sweeps in the system the remnant water in storage to draining away up. After filter's in strainer cleaning up clean, the heavy new clothing returns to the filter. (8) adds the fresh oil: Pours into the new heat conduction oil to the system. (9) dehydration: Before its dehydrated method and the new system use's dehydrated standard equates. (10) normal operation: System normal operation one month later, then takes out in system's strainer.
Some units while replace the old heat conduction oil, does not carry on the clean to the original heating system, after the replacement uses the new heat conduction oil, the effect is unable to achieve the heating system's technological requirement, investigates its reason, in the system the original coking oily dirt, the carbonization oily dirt still exists, still the serious influence was heating system's heat transfer effect. We hoped that through this work's necessary, the effective solution each Production enterprise, before using in exchange the new heat conduction oil, the thorough effective scavenging system original oil class deposition dirt, to raise system's working efficiency to complete the foundation work.
