Description
The utility model relates to the used methanol reactor of a kind of chemical industry.
Present widely used cold shocking type methanol reactor, the shell pipe type methanol reactor, though have his own strong points, all there is the shortcoming that can't overcome separately in cold-tube type methanol reactors etc.Cold shocking type methanol reactor temperature is sensitive inadequately, temperature fluctuation will occur inevitably, and circulation power consumption is bigger.Shell pipe type methanol reactor packing factor is little, and Machine Design requires high, and manufacture difficulty is big, the equipment cost height.The beds temperature difference of cold-tube type methanol reactor is big, the bad control of temperature, and overheating problem happens occasionally, and is not easy to operate, and transformation efficiency is not high.
The purpose of this utility model is exactly in order to address the above problem, the reliable controlling reactor catalytic bed of a kind of energy temperature is provided, it is close to make catalytic bed temperature distribution and ideal power learn condition, and it is big and easy to manufacture to reach combined coefficient height and packing factor, the telescoping methanol reactor that cost is low.
Technical solution of the present utility model:
A kind of telescoping methanol reactor, it is characterized in that it has a cavity (2) that has chuck (1) at least, big portion loading catalyst constitutes catalytic bed (3) in this cavity (2), on in it, the bottom is provided with little air chamber (4), (5), and the little air chamber of cavity (2) internal upper part (4) is communicated with inlet pipe (6), the little air chamber in its underpart (5) is connected with escape pipe (7), be provided with spiral pipe (8) in the interior catalytic bed of cavity (2) (3), the lower port of this coil pipe (8) is connected with the chuck (1) of cavity (2) lower end part, its upper port is connected with the chuck (1) at position, cavity (2) upper end, chuck (1) bottom of cavity (2) is connected with water inlet pipe (9), and chuck (1) top is connected with vapour outlet (10).
The utility model compared with prior art has following advantage:
1. the reactor batch temperature distribution is close with the ideal power condition of methyl alcohol building-up reactions, makes reactor have high transformation efficiency.
2. reactor catalyst volume packing factor is big.Catalyzer easily reduces, and does not have overheated danger.
3. come conditioned reaction device service temperature by the control vapor pressure, make temperature control sensitive reliable.
4. reclaim reaction heat with higher potential energy, heat energy utilization is reasonable.
5. can realize the more catalyst changeout that do not stop.
6. apparatus processing is easy to manufacture, and cost is low, uses easy to maintenance, safe and reliable.
Fig. 1 is the utility model structural representation.
As Fig. 1, the inlet pipe (6) that the little air chamber of cavity of the present utility model (2) internal upper part (4) is communicated with is preferably introduced from cavity (2) bottom, and the catalytic bed (3) of passing in the cavity (2) enters the little air chamber in top (4).Reactor of the present utility model also can be made up of the cavity (2) of two or more strap clamp covers (1), the inlet pipe (6) of each cavity (2), escape pipe (7), water inlet pipe (9) and vapour outlet (10) are corresponding respectively to be connected, wherein each inlet pipe (6) and water inlet pipe (9) all the sparger (10) by separately be connected, each escape pipe (7) and vapour outlet (11) all collector (12) by separately are connected.How many numbers of the cavity (2) that this reactor is used can determining according to production output.
During the utility model work, earlier in the chuck (1) of cavity (2), introduce saturation water from water inlet pipe (9), synthetic raw gas enters cavity (2) through gas distributor (11) from inlet pipe (6), and pass the little air chamber (4) of catalytic bed (3) to cavity (2) internal upper part, return to catalytic bed (3) then and under catalyst action, carry out building-up reactions, the reaction liberated heat is by cavity (2) inwall, spiral pipe (8) and inlet pipe (6) are passed to the unstripped gas in interior saturation water of chuck (1) and the inlet pipe (6), make the saturation water explosive evaporatoin produce steam so on the one hand, steam is discharged from vapour outlet (10), need to be used to the place of steam heating, the unstripped gas temperature is improved.Remove reaction heat owing to adopt saturation water, water side thermal resistance is less, entire thermal resistance is mainly controlled by the gas side, adopted cooling spiral coil pipe (8) and air-flow cross-flow to make the coefficient of heat transfer bigger again in the gas side, therefore total coefficient of heat transfer of the utility model catalytic bed (3) heat exchange is bigger, it can control the catalytic bed temperature effectively, make bed temperature distribution isothermal substantially vertically, unstripped gas and reaction gas are countercurrent flows simultaneously, it can make the temperature in catalytic bed (3) exit on the low side, so more helps improving transformation efficiency.Reaction back synthetic gas is flowed in the collector (12) by escape pipe of the present utility model (7), enters down road refrigerated separation operation.The steam that saturation water explosive evaporatoin in the chuck (1) of cavity (2) produces is sent into drum through header.
