Abstract
The utility model relates to a separate heat pipe type dimethyl ether reactor which comprises a reactor housing, a heat conduction pipe, catalyzer and a packed ball. The heat conduction pipe is fixed in the reactor housing, in which the catalyzer is filled. The air inlet on the top of the reactor and the air outlet at the bottom of the reactor are filled in the packed balls. The heat conduction pipe of the reactor of the the utility model adopts that the heat conduction fluid is vapoured and boiled in the pipe to heat transmission or guide the reaction heat out quickly, ensuring the temperature stability of the reaction bed, and truly realizing the minimum temperature difference between the radial direction and surface of the reaction bed and the axis direction to make the carbinol gas phase dehydration conversion rate always staying above eighty per cent.
Description
Technical field
The utility model relates to a kind of separating heat tube type dimethyl ether reactor.
Background technology
Because methanol vapor phase method dewatering preparing dimethy ether, its catalyst activity temperature height, catalyzer use initial stage and latter temperature difference are big, and traditional cold shock formula, cooling pipe type reactor all cannot say for sure to demonstrate,prove the timely derivation of bed reaction heat, so just make that reactivity is low, system's steam consumption is big.And traditional cold shock formula, cooling pipe type reactor also are subjected to the restriction of the distance of the height of equipment and position.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned shortcoming that existing installation exists, a kind of separating heat tube type dimethyl ether reactor is provided, the heat pipe of this reactor is to adopt conductive fluid vaporization boiling and condensation heat transfer in pipe, can in time reaction heat be derived fast, the temperature that has guaranteed reaction bed is steady, real realization response bed is isoplanar and axial temperature difference minimum radially, and the methanol gas phase dehydration transformation efficiency is remained on more than 80% for a long time.
The technical solution of the utility model is as follows:
The separating heat tube type dimethyl ether reactor, form by reactor shell, heat pipe, catalyzer and filling ball, at the reactor shell internal fixing heat pipe is arranged, catalyst filling around the heat pipe, fill with filling ball at the inlet mouth place, upper end and the lower end liquid outlet place of reactor.
The utility model can conveniently be used for a plurality of heat-exchange equipments that system needs heating to the reaction heat of deriving: as vaporizer, boiling etc. again, and be not subjected to the position distance, the height restriction, thereby it is minimum that steam consumption is reduced to, and produces one ton of dme system consumption steam and reduce to below 1.5 tons from 3.2 tons.The utility model is also applicable to other gas-solid phase reaction.
Description of drawings
Fig. 1 is 1 structural representation of the present utility model.
Fig. 2 is the vaporizer synoptic diagram of methanol gas phase dewatering preparing dimethy ether system.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings.
The utility model separating heat tube type dimethyl ether reactor, as shown in Figure 1, form by reactor shell 1, heat pipe 2, catalyzer 3 and filling ball 4, at reactor shell 1 internal fixing heat pipe 2 is arranged, catalyst filling 3 around the heat pipe 2, fill with filling ball 4 at the inlet mouth place, upper end and the lower end liquid outlet place of reactor.
The utility model is derived the reaction heat of reactor from heat pipe, for the methanol gas phase dewatering preparing dimethy ether system evaporator, many interchanger such as boiling use again, as shown in Figure 2.
What the upper end inlet mouth of reactor entered is gas-phase methanol, and what came out in the air outlet, lower end of reactor is dme, carbinol mixture.The liquid phase methyl alcohol that vaporizer enters, what come out is gas-phase methanol.
Be used for methanol vapor phase method dewatering preparing dimethy ether, reactor shell pressure is that normal pressure is to 1.6MPa; Heat pipe adopts metric system or the made in Great Britain pipe of diameter in φ 19 ∽ φ 60mm scopes; The ratio of catalyzer and heat pipe heat-transfer surface is used for methanol vapor phase method dewatering preparing dimethy ether time≤24m
