Abstract
Provided is a feeding heat exchanger for an ester product tower. The feeding heat exchanger for the ester product tower is used for solving the technical problems that when production of an existing ester product tower is carried out, energy waste is caused, and the production cost is increased. According to the technical scheme, the feeding heat exchanger comprises a body, a tube pass and a shell pass, wherein the tube pass and the shell pass are arranged on the body, an inlet of the tube pass or an inlet of the shell pass is communicated with a discharging outlet of a coarse ester deacidification reactor through a second feeding pipeline, and an outlet of the tube pass or an outlet of the shell pass is communicated with a feeding inlet of the ester product tower through a second discharging pipeline. The feeding heat exchanger is characterized in that the inlet of the shell pass or the inlet of the tube pass is communicated with a discharging outlet of the ester product tower through a first feeding pipeline, and the outlet of the shell pass or the outlet of the tube pass is communicated with an ester product collection device through a first discharging pipeline. The feeding heat exchanger has the advantages that only one heat exchanger is needed, the number of mechanical devices is reduced, energy resources are made full use of, and the production cost is reduced.
Description
Technical field
The utility model belongs to technical field of chemical, relates to a kind of heat exchanger, the feed exchanger that particularly ester product tower is used.
Background technology
In the production process of chemical products, the application of heat exchanger is quite general.In the production process of ester product, the temperature of charge being produced by thick ester depickling reactor only has 40 ℃, these materials need to be heated to 112 ℃ just can enter ester product tower, so need to utilize heat exchanger to heat these materials, generally with steam the tube side by heat exchanger or shell side to the shell side of heat exchanger or the heating material in tube side.The ester product temperature being produced by ester product tower is 135 ℃, need to cool to 120 ℃, just can enter next process, generally with recirculated water (28～32 ℃), as cooling agent, by the corresponding tube side of heat exchanger or shell side, reach the object of cooling, the heat that recirculated water is taken away is got back to circulating water pool and is then dispersed in atmosphere.So just need to utilize two heat exchangers can meet the needs of actual production, cause the waste of the energy, improve production cost.
Summary of the invention
The purpose of this utility model is the technical problem that to have caused the waste of the energy in order solving when existing ester product tower is produced, to have improved production cost, in order to address this problem, we have designed the feed exchanger that ester product tower is used, only need a heat exchanger, saved plant equipment, the energy is fully used, has saved production cost.
The concrete technical scheme that the utility model adopts is: the feed exchanger that ester product tower is used, comprise body, be arranged on tube side and shell side on body, the import of tube side or shell side is communicated with the discharging opening of thick ester depickling reactor by the second feed pipe, the outlet of tube side or shell side is communicated with the charging aperture of ester product tower by the second discharge pipe, key is: described shell side or the import of tube side are communicated with the discharging opening of ester product tower by the first feed pipe, and the outlet of shell side or tube side is communicated with ester product collecting device by the first discharge pipe.
The beneficial effects of the utility model are: utilize the heat of ester product to heat the material of thick ester depickling reactor generation, reduce the temperature of self simultaneously, saved plant equipment, the energy is fully used, saved production cost.The first temperature sensor and the second temperature sensor can Real-time Collection tube side and shell side in temperature, and temperature information is exported to control device, utilize control device to control the on off state of the first inlet valve, the first outlet valve, the second inlet valve and the second outlet valve, automation mechanized operation, has improved operating efficiency.
