Description
Technical field
The utility model relates to thermocirculator, particularly relates to waste heat conduction oil EGR, belongs to electrolytic aluminium anode production system calcining petroleum coke rotary kiln UTILIZATION OF VESIDUAL HEAT IN technical field.
Background technology
At present, in the aluminium anode production system, there is increasing factory to adopt the method that is arranged in parallel waste heat boiler and waste heat heat transfer oil heater at the afterbody of calcining petroleum coke rotary kiln, when obtaining steam, also obtain the required conduction oil heat supply of anode production system, save fuel cost, reduced cost.Paste producing high building portion and asphalt melting workshop need the conduction oil heat supply of two kinds of temperature grades, therefore waste heat heat-conducting oil heating station domestic demand is provided with the two cover circulatory systems, corresponding conduction oil circulating pump also will be provided with two covers, but the spacing of rotary kiln is certain, after having disposed waste heat boiler, there are not enough spaces that a complete waste heat heat-conducting oil heating station is set.
The utility model content
The purpose of this utility model is: a kind of waste heat conduction oil EGR is provided, and it is separated from waste heat heat-conducting oil heating station and carries out independent setting, has saved pipeline and has arranged, and it is little to take up room, to overcome the deficiency of present technology.
The utility model is achieved in that waste heat conduction oil EGR comprises high temperature oil return pipe (6), low temperature oil return pipe (8), high temperature oil return pipe (6) is connected with heating station oil return house steward (10) respectively with low temperature oil return pipe (8), heating station fuel feed pump (3) connects high-temperature pump inlet tube (4) and cryogenic pump inlet tube (5) respectively, high temperature oil return pipe (6) is provided with high temperature oil returning branch pipe (7) and is connected with high-temperature pump inlet tube (4), high-temperature pump inlet tube (4) connects the inlet of high temperature heat conductive oil circulating pump (1), the outlet of high temperature heat conductive oil circulating pump (1) is connected with high temperature circulation pipe (11), low temperature oil return pipe (8) is provided with low temperature oil returning branch pipe (9) and is connected with cryogenic pump inlet tube (5), cryogenic pump inlet tube (5) connects the inlet of low temperature conduction oil circulating pump (2), and the outlet of low temperature conduction oil circulating pump (2) is connected with low temperature circulation pipe (12).
Described pipeline and equipment are arranged in the independent station.
Owing to adopted technique scheme, compared with prior art, the utility model carries out independent setting in that the conduction oil circulatory system is separated from waste heat heat-conducting oil heating station, equipment in the waste heat heat-conducting oil heating station and pipeline have all reduced much like this, substantially can between two waste heat boilers, dispose, so both utilized the rotary kiln waste heat to heat conduction oil, can guarantee that again the anode production system confesses the conduction oil of two kinds of required temperature grades, and pipeline is arranged simply, has saved big quantity space.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: waste heat conduction oil EGR as shown in Figure 1, high temperature oil return pipe 6 is connected with heating station oil return house steward 10 respectively with low temperature oil return pipe 8, heating station fuel feed pump 3 connects high-temperature pump inlet tube 4 and cryogenic pump inlet tube 5 respectively, high temperature oil return pipe 6 is provided with high temperature oil returning branch pipe 7 and is connected with high-temperature pump inlet tube 4, high-temperature pump inlet tube 4 connects the inlet of high temperature heat conductive oil circulating pump 1, the outlet of high temperature heat conductive oil circulating pump 1 is connected with high temperature circulation pipe 11, low temperature oil return pipe 8 is provided with low temperature oil returning branch pipe 9 and is connected with cryogenic pump inlet tube 5, cryogenic pump inlet tube 5 connects the inlet of low temperature conduction oil circulating pump 2, and the outlet of low temperature conduction oil circulating pump 2 is connected with low temperature circulation pipe 12.
In use, waste heat heat-conducting oil heating station is sent into oil respectively in high-temperature pump inlet tube 4 and the cryogenic pump inlet tube 5 by heating station fuel feed pump 3, the oil that the high temperature oil returning branch pipe 7 that high temperature oil return pipe 6 connects imports enters in the high-temperature pump inlet tube 4, oil return in conduction oil fuel feeding in the high-temperature pump inlet tube 4 and the high temperature oil returning branch pipe 7 is mixed into temperature required conduction oil, and is sent in the asphalt melting groove in paste producing high building portion preheating spiral and asphalt melting workshop by high temperature circulation pipe 11 by high temperature heat conductive oil circulating pump 1; Oil return in conduction oil fuel feeding in the cryogenic pump inlet tube 5 and the low temperature oil returning branch pipe 9 is mixed into temperature required conduction oil, delivers to the low temperature user in paste producing high building portion and asphalt melting workshop through low temperature conduction oil circulating pump 2.The low temperature oil return pipe 8 in the high temperature oil return pipe 6 of paste producing high building portion preheating spiral and asphalt melting workshop asphalt melting groove and paste producing high building portion and asphalt melting workshop is merged into a heating station oil return house steward 10 after pipe network is sent waste heat heat-conducting oil heating station back in waste heat conduction oil circulatory system station.Both utilized the rotary kiln waste heat to heat conduction oil, and can guarantee that again the anode production system confessed the conduction oil of two kinds of required temperature grades.
Above-mentioned pipeline and equipment are arranged in the independent station, the conduction oil circulatory system separated from waste heat heat-conducting oil heating station carry out independent setting, equipment and pipeline in the heating station have been reduced, and conduction oil circulatory system station can be provided with near paste producing high building portion and asphalt melting workshop, shortened circulation line greatly, both can guarantee the stable operation of the high and low temperature circulatory system, save steel again.
