Description
Technical field
The utility model belongs to chemical industry equipment field, is specifically related to a kind of weight-removing column heater that replaces steam heater.
Background technology
At present in gasoline hydrogenation technique, weight-removing column is heated at the bottom of adopting Steam Heating to tower, the increase that this is extra the consumption of steam; And in gasoline hydrogenation technique, require the tower top temperature of fractionating column low, to make oil gas better carry out separation, this needs extra condenser to make the gas mixture of tower top after condenser cooling, turn back to the tower top of fractionating column again.In two different workshop sections, need extra increase steam heater and condenser like this, increased use cost, cause the heat of recycle oil in fractionating column be not fully utilized and waste, and increased the cooling load of fractionator overhead condenser.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of weight-removing column heater, utilize the steam heater at the bottom of the overheated surplus of fractionator overhead recycle oil replaces weight-removing column tower, not only reduced the cooling load of fractionator overhead condenser, also the consumption of having saved heating steam, greatly reduces production cost.
Concrete technical scheme of the present utility model is:
A kind of weight-removing column heater, comprise fractionating column and weight-removing column, between fractionating column and weight-removing column, be provided with storage heater, described fractionator overhead output channel I is connected with tower top input channel III by pump, pipeline II, condenser successively, described pipeline II is connected by circulating line III with storage heater, and described storage heater is connected with pipeline II by circulating line IV; At the bottom of described weight-removing column tower, by output channel V at the bottom of tower, be connected with storage heater, described storage heater by tower at the bottom of input channel VI be connected with at the bottom of weight-removing column tower.
Adopt such syndeton, light component in fractionating column is from tower top output channel I is passed through pump, part light component enters storage heater accumulation of heat cooling from pipeline II through circulating line III, through circulating line IV, enter pipeline II again, with from tower top output channel I, another part light component by pump mixes in pipeline II, through condenser, cool, by tower top input channel III, be back to fractionator overhead, make like this temperature of fractionator overhead reduce as much as possible, to make oil gas better carry out separation; Simultaneously, heavy constituent at the bottom of weight-removing column tower by tower at the bottom of output channel V enter storage heater heat temperature raising, then by the bottom of at the bottom of tower, input channel VI is back to weight-removing column tower, utilize so the overheated surplus of fractionator overhead recycle oil, replaced the steam heater at the bottom of weight-removing column tower, not only reduce the cooling load of fractionator overhead condenser, also saved the consumption of heating steam, greatly reduced production cost.
In described pipeline II, be provided with valve I, in described circulating line III, be provided with valve II, in described circulating line IV, be provided with valve III, to make storage heater can maintain better whole technical load.
The utility model utilizes the steam heater at the bottom of the overheated surplus of fractionator overhead recycle oil replaces weight-removing column tower, has not only reduced the cooling load of fractionator overhead condenser, has also saved the consumption of heating steam, greatly reduces production cost.

In figure, 1 is fractionating column, the 2nd, and tower top output channel I, the 3rd, pump, the 4th, valve II, the 5th, circulating line III, the 6th, storage heater, the 7th, output channel V at the bottom of tower, the 8th, weight-removing column, the 9th, input channel VI at the bottom of tower, the 10th, circulating line IV, the 11st, valve III, the 12nd, valve I, the 13rd, pipeline II, the 14th, condenser, the 15th, tower top input channel III.
The specific embodiment
A kind of weight-removing column heater, comprise fractionating column 1 and weight-removing column 8, between fractionating column 1 and weight-removing column 8, be provided with storage heater 6, described fractionating column 1 tower top output channel I 2 is connected with tower top input channel III 15 by pump 3, pipeline II 13, condenser 14 successively, described pipeline II 13 is connected by circulating line III 5 with storage heater 6, and described storage heater 6 is connected with pipeline II 13 by circulating line IV 10; At the bottom of described weight-removing column 8 towers, by output channel V 7 at the bottom of tower, be connected with storage heater 6, described storage heater 6 is connected with at the bottom of weight-removing column 8 towers by input channel VI 9 at the bottom of tower.
Adopt such syndeton, light component in fractionating column 1 passes through pump 3 from tower top output channel I 2, part light component enters storage heater 6 accumulation of heat coolings from pipeline II 13 through circulating line III 5, through circulating line IV 10, enter pipeline II 13 again, with from tower top output channel I 2, another part light component by pump 3 mixes in pipeline II 13, through condenser 14, cool, by tower top input channel III 15, be back to fractionating column 1 tower top, make like this temperature of fractionating column 1 tower top reduce as much as possible, to make oil gas better carry out separation; Simultaneously, heavy constituent at the bottom of weight-removing column 8 towers by tower at the bottom of output channel V 7 enter storage heater 6 heat temperature raisings, then at the bottom of being back to weight-removing column 8 towers by input channel VI 9 at the bottom of tower, utilize so the overheated surplus of fractionating column 1 tower top recycle oil, replaced the steam heater at the bottom of weight-removing column 8 towers, not only reduce the cooling load of fractionating column 1 overhead condenser 14, also saved the consumption of heating steam, greatly reduced production cost.
In described pipeline II 13, be provided with valve I 12, in described circulating line III 5, be provided with valve II 4, in described circulating line IV 10, be provided with valve III 11, to make storage heater 6 can maintain better whole technical load.
