Abstract
The utility model provides an auxiliary heater of a pre-reactor in a low-temperature hydrogenation and benzene-production process, comprising an auxiliary heater body, wherein the auxiliary heater body is arranged on an inlet pipeline of the pre-reactor and comprises a heat-conducting oil heater provided with an adjusting valve. The auxiliary heater provided in the utility model has the advantages of a simple structure, convenience and reliability in adjustment and capability of meeting heat requirements of the pre-reactor in each time period; and meanwhile, the load of an electric heater is reduced, the service life of the electric heater is prolonged and electricity consumption amounts are reduced, so that the processing cost of products is reduced.
Description
Technical field
The utility model relates to a kind of heater, is specifically related to the auxiliary heater of pre-reactor in a kind of low temperature hydrogenation system benzene process.
Background technology
In the present low temperature hydrogenation system benzene technology; The thermal source of pre-reactor mainly comes from electric heater and evaporimeter reboiler; But often satisfied not the heating requirements of pre-reactor; Especially when main device is driven parking and catalyst regeneration heating, depend merely on the thermal source of electric heater and evaporimeter, satisfied not the well-defined reaction temp requirement of pre-reactor far away; And when normal operation, the load of electric heater is very big, and the running of high load capacity can be shortened the service life of electric heater, increases power consumption, improves the product processing charges.
The utility model content
The utility model technical problem to be solved provides the auxiliary heater of pre-reactor in a kind of low temperature hydrogenation system benzene process; It is simple in structure; Can satisfy the heat demand in each stage of pre-reactor, reduce the load of electric heater, thereby eliminate defective in the above-mentioned background technology.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The auxiliary heater of pre-reactor comprises the auxiliary heater body in a kind of low temperature hydrogenation system benzene process, it is characterized in that, said auxiliary heater body is arranged on the inlet pipeline of said pre-reactor.
As a kind of improvement, said auxiliary heater body comprises hotline heater.
As a kind of further improvement, said hotline heater is provided with the adjusting device that is used to regulate the conduction oil flow.
As a kind of further improvement, said adjusting device comprises control valve.
Owing to adopted above structure, the utlity model has following beneficial effect:
Install the auxiliary heater body additional on the pre-reactor inlet pipeline of the utility model after the outlet of unstripped gas superheater; Extraly heat is provided for pre-reactor; Can satisfy the heat demand of each time period of pre-reactor; Heat demand when for example main device is driven parking and catalyst regeneration heating, and reduced dependence to electric heater and evaporimeter thermal source, reduced the load of electric heater simultaneously.
The auxiliary heater body of the utility model comprises that install adjustment valve can be controlled the material temperature that gets into pre-reactor through the flow of regulating conduction oil as the hotline heater of adjusting device on it, and is safe and reliable.
Can know that to sum up the utility model is simple in structure, easy to adjust reliable; Can satisfy the heat demand of each time period of pre-reactor, reduce the load of electric heater simultaneously, increase the service life of electric heater; Reduce power consumption, thereby reduced the processing charges of product.
