Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
The typical embodiment according to the present invention, as shown in Figure 1, condenser comprises elementary vertical (type) condenser 410, secondary vertical condensationDevice 420 and condenser lime set tank 430, wherein, at the beginning of elementary vertical (type) condenser 410 comprises elementary vertical (type) condenser shell side and is arranged onElementary vertical (type) condenser tube side in level vertical (type) condenser shell side; Secondary vertical (type) condenser 420 comprises secondary vertical (type) condenser shell sideWith the secondary vertical (type) condenser tube side being arranged in secondary vertical (type) condenser shell side, secondary vertical (type) condenser 420 is arranged on elementary verticalThe top of formula condenser, and elementary vertical (type) condenser tube side and secondary vertical (type) condenser tube side be connected, elementary vertical (type) condenser topPortion is provided with the first distance piece for elementary vertical (type) condenser shell side and secondary vertical (type) condenser shell side are separated; Condenser is solidifyingFlow container 430 is arranged on the bottom of elementary vertical (type) condenser, communicates with elementary vertical (type) condenser tube side. Apply technical side of the present inventionCase, owing to being provided with primary and secondary condensed in two stages device, and the tube side of condensed in two stages device communicates, at the beginning of condenser condenses tank is arranged onMore thick methanol product due to through condensed in two stages, therefore can be isolated in the bottom of level condenser from reaction generation gas.And elementary vertical (type) condenser shell side and secondary vertical (type) condenser shell side are spaced apart by distance piece, can use different coldBut medium, in the area of water resources shortage, only part makes water as cooling medium, using water wisely.
Preferably, each elementary vertical (type) condenser tube side layout parallel to each other, and be vertically arranged in elementary vertical (type) condenser shell side,And elementary vertical (type) condenser tube side extends upwardly to the secondary vertical (type) condenser tube side of formation in secondary vertical (type) condenser shell side; ElementaryOn vertical (type) condenser shell side and secondary vertical (type) condenser shell side, be provided with cooling medium inlet tube and cooling medium outlet. Like thisMaterial by tube side can carry out heat exchange through the medium in two-stage shell side equably.
Preferably, cooling medium inlet tube and cooling medium outlet are respectively arranged with flow control valve, facilitate cooling medium flowControl.
The typical embodiment according to the present invention, as shown in Figure 1, is provided with and elementary vertical condensation on elementary vertical (type) condenser 410The first cooling medium inlet tube 411 that device shell side communicates and the first cooling medium outlet 412. On secondary vertical (type) condenser 420, establishBe equipped with the second cooling medium inlet tube 421, the second cooling medium outlet 422 that communicate with secondary vertical (type) condenser shell side. Wherein,The cooling medium of elementary vertical (type) condenser 410 can be cooling-air or recirculated water. The one typical embodiment according to the present invention, theTwo cooling medium inlet tubes 421 are away from one end and condensation of gas medium inlet pipe 423 and the liquid cooling of secondary vertical (type) condenser 420Solidifying medium inlet pipe 425 is connected; The second cooling medium outlet 422 is provided with away from one end of secondary vertical (type) condenser 420Condensation of gas media outlet pipe 424 and condenses media outlet pipe 426, the cooling medium of level vertical (type) condenser 420 can be selectedBe cooling-air or recirculated water, condensation of gas media outlet pipe 424 again with the first cooling medium outlet 412 after control valveBe connected; The first cooling medium inlet tube 411 and the first cooling medium outlet 412 are with elementary vertical (type) condenser 410 geometric centersPoint symmetry, the second cooling medium inlet tube 421 and the second cooling medium outlet 422 are with in secondary vertical (type) condenser 420 geometryHeart point symmetry. In the time that environment temperature is lower, adopt air cooled mode cooling, when the higher cooling-air of environment temperature cannot be expiredWhen cooling requirement of foot, can close the cooling-air admission line valve of secondary vertical (type) condenser 420, adjust recirculated water oral siphon lineValve opening adopts circulating water reaction to generate gas.
Preferably, secondary vertical (type) condenser 420 tops are provided with the circulating air communicating with secondary vertical (type) condenser tube side and enter pipe 427,On the sidewall of condenser lime set tank 430, be provided with circulating air discharge pipe 432, be convenient to medium in material and the shell side of tube side abundantHeat exchange. Preferably, thick methyl alcohol outlet 433 is arranged on the bottom of condenser lime set tank 430, facilitates drawing of thick methyl alcohol. FirstDistance piece is the parts that can play interval action, and preferably, the first distance piece is dividing plate 428, and cost is low, easy to use.
The typical embodiment according to the present invention, secondary vertical (type) condenser 420 inside can be horizontally disposed with multiple for by secondary verticalCondenser shell side is divided into the second distance piece of multiple separate space, is provided with cooling medium and enters on the shell side of multiple separate spaceMouth pipe and cooling medium outlet. Wherein, in the space of each separate space, can pass into different cooling mediums, according to realityNeed, increase the washability of degree of condensation and medium.
In system for methanol synthesis, because condenser of the present invention adopts vertical structure, the thick methyl alcohol that condensation is got off falls into condenserIn lime set tank 430, minimizing circulating air carries too much methyl alcohol and enters synthesis reactor, avoids the generation of too much wax (in reaction gasThe too high meeting of methanol content causes the growing amount of wax in building-up process to increase, and methanol output also can decline thereupon; If keepMethanol output, just need to strengthen internal circulating load and the cycle-index of unreacted synthesis gas, and this has increased again energy consumption undoubtedly), and condensationThe thick methyl alcohol getting off is admitted to thick methanol stripper fixed gas, residual solution gas and low-boiling-point substance system and removes fixed gas, residual dissolvingGas and low-boiling-point substance. In a word, condenser of the present invention is applied in methanol synthetizing technology and method, in equal air inflow, identicalUnder composition, the equal filling condition of catalyst and service time same period condition, due to by more thick methanol product in reaction gas coldIn condenser, remove, therefore, still less, still less, methanol output is larger for the methane of generation for the wax of generation.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art, the present invention can have various modifications and variations. Within the spirit and principles in the present invention all, any amendment of doing, etc.With replacement, improvement etc., within all should being included in protection scope of the present invention.
