Abstract
The utility model relates to a chemical industry equipment technical field provides a methyl tert butyl ether extrinsic cycle production line very much, including raw materials inlet wire and extrinsic cycle reactant inlet wire, the raw materials inlet wire is including the blender and the pre-heater of connecting in order, extrinsic cycle reactant inlet wire is including the reactor of connecting in order, extrinsic cycle pump and cooler, and pipeline that comes out from the cooler is one through the preceding pipe connection of first valve with the blender, and another pipeline that comes out from the pre-heater through the second valve is connected to the reactor upper end again after merging with the pipeline at second valve place on the pre-heater. This is novel can enough make raw materials and extrinsic cycle reactant get into the preheater together and preheat, also can only directly preheat for the raw materials heats, gets into the reactor together with extrinsic cycle reactant again, can satisfy required preheating temperature, improves the availability factor and the life-span of catalyst.
Description
Technical Field
The utility model relates to a chemical industry equipment technical field provides a methyl tert butyl ether extrinsic cycle production line very much.
Background
In the production process of the methyl tert-butyl ether, because the heat exchange area of the preheater is small, when the external circulation amount is increased, if the external circulation amount is mixed with the raw materials, the mixture enters the preheater and then returns to the reactor, the temperature required by the reaction in the reactor cannot be reached, so that the conversion rate ensured by the preheating temperature of the catalyst in the middle and later stages cannot be reached, and the service efficiency and the service life of the catalyst are reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a methyl tert butyl ether extrinsic cycle production line.
The utility model discloses a realize like this, a methyl tert butyl ether extrinsic cycle production line, including raw materials inlet wire and extrinsic cycle reactant inlet wire, the raw materials inlet wire is including the blender and the pre-heater of connecting in order, and extrinsic cycle reactant inlet wire is including the reactor of connecting in order, extrinsic cycle pump and cooler, and pipeline that comes out from the cooler is one through the preceding line connection of first valve with the blender, and another pipeline that comes out from the pre-heater through the second valve is connected to the reactor upper end again after merging with the pipeline at second valve place on the pre-heater.
Furthermore, a third valve is arranged between the reactor and the external circulating pump, a final product outlet pipeline is also arranged below the reactor, and a fourth valve is arranged on the final product outlet pipeline.
Compared with the prior art, the utility model has the advantages of: the raw materials and the external circulation reactants can enter the preheater for preheating, or the raw materials can be directly heated and preheated, and then the raw materials and the external circulation reactants enter the reactor together, so that the required preheating temperature can be met, the service efficiency of the catalyst is improved, and the service life of the catalyst is prolonged.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the utility model provides a methyl tert butyl ether extrinsic cycle production line, including raw materials inlet wire and extrinsic cycle reactant inlet wire, the raw materials inlet wire is including blender 1 and the pre-heater 2 that connects in order, extrinsic cycle reactant inlet wire is including the reactor 3 that connects in order, extrinsic cycle pump 4 and cooler 5, pipeline one that comes out from cooler 5 is through the preceding line connection of first valve 6 with blender 1, another pipeline connection that comes out from pre-heater 2 through second valve 7, be connected to reactor 3 upper end again after the pipeline that comes out on the pre-heater 2 merges with the pipeline at second valve 7 place.
A third valve 8 is arranged between the reactor 3 and the external circulating pump 4, a final product outlet pipeline is also arranged below the reactor 3, and a fourth valve 9 is arranged on the final product outlet pipeline.
When the production line is utilized to produce methyl tert-butyl ether, when the reactor does not need higher reaction temperature or the volume of the preheater 2 is large enough, the external circulation reactant comes out of the reactor 3, is cooled through the external circulation pump 4 and the cooler 5, passes through the first valve 6, enters the mixer 1 together with the raw material to be mixed, then enters the preheater 2 to be preheated, and then returns to the reactor 3 together to be reacted, when the reactor contains catalyst which needs higher reaction temperature or the volume of the preheater 2 is small, the external circulation reactant comes out of the reactor 3, is cooled through the external circulation pump 4 and the cooler 5, passes through the second valve 7, the raw material passes through the mixer 1 and the preheater 2 to be mixed with the external circulation reactant, and directly enters the reactor 3 to be reacted, at this time, the raw material and the external circulation reactant are heated together, the preheater 2 heats the raw material to a relatively high temperature, and then mixes the raw material with the externally circulated reactant whose temperature is not low, so that the reaction temperature in the reactor 3 can be increased, and the reaction efficiency of the catalyst can be improved.
