Description
Technical field
The present invention relates to the heat conduction stove, particularly under a kind of dead electricity situation, prevent the heat conduction stove using method of conduction oil coking in the heat-conducting oil furnace boiler tube.
Background technology
At present, heat-conducting oil furnace is as a kind of heating furnace that higher temperature can be provided under low operating pressure condition, and its scope of application constantly enlarges.Utilize heat-conducting oil furnace that heat is delivered to the equipment that needs with heat by organic carrier, organic carrier commonly used is conduction oil.The tradition heat-conducting oil furnace basic structure as shown in Figure 2: comprise body of heater 8, expansion slot 6, oil storage tank 7, conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11, realize closed cycle at the said equipment and between with hot equipment.Its basic principle is: heat-conducting oil furnace heating conduction oil, and conduction oil flows into the hot equipment of use through pipeline, and oil return is returned heat-conducting oil furnace through expansion slot, conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 and is heated then, circulates and so forth.But conduction oil is organic media, and is inflammable and strict serviceability temperature restriction arranged.After conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 dead electricity, intrasystem conduction oil stops to flow, and furnace temperature can't reduce at short notice.Directly cause conduction oil decomposition coking in the boiler tube, influence the efficient of heat-conducting oil furnace even cause danger.Existing heat-conducting oil furnace is normally kept conduction oil and is continued circulation by starting standby diesel pump 9 under the dead electricity situation, and investment is big, needs personnel to arrive the execute-in-place valve during startup, and time-consuming length increases the risk of conduction oil coking greatly.
Summary of the invention
Invest the deficiency of big complicated operation in order to overcome existing protected mode; the invention provides heat-conducting oil furnace and the using method of conduction oil coking in a kind of anti-boiler tube; can be by switch valve 17 quick conducting protection flow processs after conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 dead electricity; conduction oil continues to flow in the assurance system, and the conduction oil that prevents from resting in the high temperature furnace pipe decomposes coking.
The technical solution adopted for the present invention to solve the technical problems is:
The heat-conducting oil furnace of conduction oil coking in a kind of anti-boiler tube is to connect dead electricity oil exit pipe 15 between heat-conducting oil furnace fuel feed pump 2 and oil storage tank 7, on the pipe 15 hand valve 16 and electromagnetic switch valve 17 is set, and electromagnetic switch valve 17 is made as dead electricity and opens; Electromagnetic switch valve and conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 interlockings.
The using method of conduction oil coking in the anti-boiler tube of heat-conducting oil furnace of the present invention, when conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 dead electricity, conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 quit work; Magnetic valve 17 dead electricity are left, and intrasystem conduction oil flows to oil storage tank 7 under pressure; Opened magnetic valve 17 in the dead electricity oil exit pipe 15 by interlocking signal during dead electricity; Utilize sealing nitrogen tube 3, in high-order expansion slot 6, replenish nitrogen, conduction oil oil return pipe 1 after conduction oil under pressure and the potential difference effect flows directly into supercharging by expansion slot subordinate line 12 ", enter heat-conducting oil furnace 8; Conduction oil in the conduction oil boiler tube enters low level oil storage tank 7 by dead electricity oil exit pipe 15.
Principle is described as follows:
Utilize sealing nitrogen tube 3 and pressure regulator valve wherein 4 on the expansion slot 6, press to guarantee the expansion drum band.Connect dead electricity oil exit pipe 15 between heat-conducting oil furnace fuel feed pump 2 and oil storage tank 7, hand valve 16 and electromagnetic switch valve 17 are set on the dead electricity oil exit pipe, wherein hand valve 16 is normally opened, and electromagnetic switch valve 17 is made as dead electricity and opens.The purpose that hand valve 16 is set is when magnetic valve 17 maintenance, cuts off dead electricity oil exit pipe 15.
Start the protection flow process fast by switch valve after conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 dead electricity, conduction oil flows in the realization system.Under the nominal situation, conduction oil oil return pipe 1 after expansion slot 6 and supercharging " between be connected expansion slot subordinate line 12, check-valves 13 and ball valve 14 are set on the expansion slot subordinate line, wherein ball valve 14 is normally opened.The effect of check-valves 13 is to prevent that conduction oil enters expansion slot 8 through the expansion slot subordinate line under the nominal situation.Conduction oil enters expansion slot 8 through conduction oil oil return pipe 1 during normal operation, and conduction oil oil return pipe 1 ' enters conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 before supercharging then, by conduction oil oil return pipe 1 after the supercharging " enter heat-conducting oil furnace 8.After heating, enter the hot equipment of using by conduction oil fuel feed pump 2.When conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 dead electricity, conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 quit work.Magnetic valve 17 dead electricity are left, and intrasystem conduction oil flows to oil storage tank under pressure.Opened magnetic valve 17 in the dead electricity oil exit pipe 15 by interlocking signal during dead electricity.Utilize sealing nitrogen tube 3, in high-order expansion slot, replenish nitrogen, conduction oil oil return pipe 1 after conduction oil under pressure and the potential difference effect flows directly into supercharging by expansion slot subordinate line 12 ", enter heat-conducting oil furnace.Conduction oil in the conduction oil boiler tube enters the low level oil storage tank by dead electricity oil exit pipe 15.Because conduction oil fuel feed pump 2 and rear end equipment pressure height thereof be not so conduction oil flows to conduction oil fuel feed pump 2 in this protection flow process.Can after conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 dead electricity, rapid conducting protect flow process like this, guarantee flowing of the interior conduction oil of boiler tube, need not increase equipment and controlled investment.If can restore electricity in the short time, conduction oil circulating pump 10 and conduction oil circulation stand-by pump 11 are opened, and close magnetic valve in the dead electricity oil exit pipe 15 by interlocking signal, and system can recover rapidly.If can't restore electricity in the short time, utilize the malleation of expansion slot will protect the conduction oil in the flow process all to enter in the oil storage tank.
The invention has the beneficial effects as follows, with the present invention's contrast, enclose original flow process at this, see Fig. 2.After the dead electricity, conduction oil circulating pump 10 and conduction oil circulating pump stand-by pump 11 stop, and personnel hurry to the scene and start standby diesel pump 9 and make conduction oil continue circulation to be unlikely to coking in boiler tube.
