Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
As shown in Figure 1-Figure 3, a kind of modified coal tar pitch outer circulation electrical heating process device of the present invention, including circulating pump
2, electric heater 3, valve (one) 4, valve (two) 5, recurrent canal 6, extraction pipe 7, thermograph regulation meter 8 and moisture recorder
Table 9, the extraction pipe 7 are arranged in the lower part of modified coal tar pitch storage tank 1, connect with 2 pipeline of circulating pump, circulating pump 2 and electric heater 3
Pipeline connection, the pipeline come out from electric heater 3 are connect with valve (two) 5 and recurrent canal 6 all the way, and the setting of recurrent canal 6 is modifying
The top of asphalt reservior 1, another way connect modified coal tar pitch liquid entrucking with valve (one) 4；The thermograph instrument 9 is arranged
On modified coal tar pitch storage tank 1, the outlet end with 3 connecting pipe of electric heater is arranged in thermograph regulation meter 8.
See that Fig. 3, the extraction pipe 7 are n, is evenly arranged in around modified coal tar pitch storage tank 1.Due to modified coal tar pitch storage tank
1 volume generally selected is all very big, so the extraction pipe 7 of modified coal tar pitch storage tank 1, which wants multiple spot to be equidistantly positioned, pumps modified coal tar pitch
Circulating pump 2 is removed, to ensure that the modified coal tar pitch of 1 bottom of modified coal tar pitch storage tank is uniformly extracted without dead angle, prevents modified coal tar pitch from heating
Unevenly.
See that Fig. 2, the recurrent canal 6 are n+1, the center at 1 top of modified coal tar pitch storage tank is arranged in one of them,
Remaining n is evenly arranged on around 1 wall of modified coal tar pitch storage tank, and is fully inserted into inside liquid modified coal tar pitch, outlet end away from
Extract distance h=100~150mm of pipe absolute altitude out.
The recurrent canal 6 is inserted into liquid modified coal tar pitch interior section and is respectively provided with several spray holes 61.
The electric heater 3 uses variable power form, in order to be heated in liquid modified coal tar pitch entrucking
To the temperature of needs, in this way, the holding temperature of modified coal tar pitch storage tank 1 can be reduced, the energy is saved.
Between the thermograph regulation meter 8 and thermograph instrument 9 and between circulating pump 2 and electric heater 3
Chain control.
A kind of modified coal tar pitch outer circulation electrical heating process, comprising the following steps:
1) to the modified coal tar pitch heating in modified coal tar pitch storage tank 1: when thermograph instrument 9 is examined and determine in modified coal tar pitch storage tank 1
Modified coal tar pitch temperature be lower than setting value when, Open valve (two) 5, close valve (one) 4, start circulating pump 2, by modified coal tar pitch from
By extraction 7 multiple spot of pipe extraction in modified coal tar pitch storage tank 1, it is sent to after electric heater 3 is heated to the temperature of setting, through valve (two)
5, it is returned in modified coal tar pitch storage tank 1 by 6 multiple spot of recurrent canal；It examines and determine in modified coal tar pitch storage tank 1 and modifies when thermograph instrument 9
When asphalt temperature >=setting value, circulating pump 2 is closed, stops heating work.
2) it send modified coal tar pitch to go liquid entrucking: closing valve (two) 5, Open valve (one) 1, start circulating pump 2, will modify
Pitch out of modified coal tar pitch storage tank 1 by extraction 7 multiple spot of pipe extraction, be sent to electric heater 3 be heated to setting temperature after, through valve
Door (one) 4 sends to modified coal tar pitch liquid entrucking.When liquid asphalt sends to liquid entrucking, thermograph tune can be adjusted as needed
The control temperature for saving instrument 8 makes modified coal tar pitch keep higher temperature, to guarantee the needs of long-distance transport.
Further, it is the safety for protecting electric heater 3, prevents 3 inside modified coal tar pitch of electric heater from the possibility of coking occur,
Electric heater 3 and circulating pump 2 need interlocked control, it is necessary to which, in the case where circulating pump 2 operates, electric heater 3 is just heated
Work, otherwise, it is necessary to shut down.
Further, it after the display of 1 temperature recording apparatus (TR02) 9 of modified coal tar pitch storage tank reaches predetermined temperature, can fit
Degree turns down the control temperature of thermograph regulation meter (TRC01) 9, in case heating temperature is too high, waste of energy.
