Abstract
The utility model discloses an energy-saving type aromatization reaction heating system, wherein an input pipeline is connected with the left end of a raw material reaction product heat exchanger via a raw material mixing valve group; the right end of the raw material reaction product heat exchanger is connected with the input end of a dediazoniation tower-bottom reboiler via a heating furnace and a reactor; the output end of the dediazoniation tower-bottom reboiler is connected with the input end of a stabilization tower-bottom reboiler; the output end of the stabilization tower-bottom reboiler is connected with the upper end of the raw material reaction product heat exchanger; and the lower end of the raw material reaction product heat exchanger is connected with an absorption-desorption tower after passing through an air cooler, a water cooler and a conveying valve group. The energy-saving type aromatization reaction heating system disclosed by the utility model is simple to operate; and a compressor is used during a work starting period, so that relative stability can be kept during an oil inlet process, the stable change of the pressure of the system can be kept, and then the furnace outlet temperature of the reaction heating furnace can be stably controlled, thus creating conditions for the stable operation of the system, realizing stable production, reducing lots of electric quantity, and creating more economic benefits.
Description
Technical field
The utility model relates to the aromatization technical field, is specifically related to a kind of energy-saving aromatization heating system.
Background technology
The aromizing production technique is used resurgent gases compressor band oil between under-stream period, cause the fluctuation of system pressure in the process of band oil, the fluctuation of pressure can cause the fluctuation of furnace temp, cause vicious cycle, make troubles to operation, and compressor rated output is very large, has consumed a large amount of electric weight in start-up process, has caused the waste of the energy.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of energy-saving aromatization heating system is provided.
Its technical scheme is: comprise reboiler at the bottom of raw material mixing valve group, raw material reaction product interchanger, process furnace, reactor, weight-removing column, stablize tower bottom reboiler, absorb Analytic Tower, air cooler, water cooler and transfer valve group.Input channel is connected by the left end of raw material mixing valve group with raw material reaction product interchanger, the right-hand member of raw material reaction product interchanger is connected with the input terminus of reboiler at the bottom of weight-removing column by process furnace and reactor, at the bottom of weight-removing column, the output terminal of reboiler is connected with the input terminus of stable tower bottom reboiler, the output terminal of stablizing tower bottom reboiler is connected with the upper end of raw material reaction product interchanger, the lower end of raw material reaction product interchanger by air cooler, water cooler and transfer valve group after with absorb Analytic Tower and be connected.
The utility model is simple to operate, get rid of between under-stream period and use compressor, can keep in the process of oil-feed relative steadily, can change stably by keeping system pressure, and then can control stably the reaction heating furnace heater outlet temperature, and having created condition for the quiet run of system, can produce stably, reduce a large amount of electric weight, created more economic benefit.
