Abstract

The utility model provides a shell and tube heat exchange reactor belongs to the chemical industry and equips the field, is particularly useful for needing fixed catalyst and the big reaction process of calorific capacity, and its main implementation is as follows: firstly, two tube plates are arranged, a metal tube is arranged between the two tube plates to serve as a heat exchange tube array, meanwhile, metal tank bodies are arranged outside the tube plates and the tube array, three cavities are formed in the tank bodies, namely two cooling medium storage cavities at two ends and a reaction cavity in the middle, catalytic fins are arranged on the heat exchange tube array and consist of catalyst metal elements: fe. Cu, Pb, Mu and Mn; finally, the three cavities are respectively provided with a cooling medium inlet, a cooling medium outlet, a reaction material inlet and a reaction material outlet; therefore, when the device works, the reaction materials are in contact with the catalytic fins on the heat exchange tubes for reaction, and the catalytic fins can timely remove the reaction heat while catalyzing the reaction.

Description

A kind of shell and tube heat transfer reactor

Technical field:

A kind of shell and tube heat transfer reactor belongs to the chemical equipment field, needing to be particularly useful for fixed catalyst and the big course of reaction of caloric value.

Background technology:

Some need fixed catalyst and the big chemical process of reaction caloric value, and like Fischer-Tropsch legal system liquefaction coal, its reaction equation is CO+H₂→-CH₂-CH₂-+H₂O, catalyst are compound such as FeS, the Fe that contains Fe₂O₃Deng, because a large amount of heat releases of course of reaction like untimely discharge heat, can influence reaction process.

Summary of the invention:

Can in time get rid of heat of reaction for providing a kind of, and the firm reactor of structure, propose a kind of based on the heat transfer reactor on the tubular heat exchanger basis at present; Its main implementation is following: at first, establish two tube sheets, intensive perforate on two tube sheets; And between two tube sheets, establish metal tube, as heat exchanging pipe, the heat exchanging pipe port is connected with the tube sheet perforate; Simultaneously, form three cavitys in tube sheet and the tubulation peripheral hardware metal can, said tank body; Be two the cooling medium storage chambers in two ends, middle reaction chamber just has a large amount of heat exchanging pipes in the said reaction chamber; On said heat exchanging pipe, establish the catalysis fin, said catalysis fin by the catalyst metals element as: Fe, Cu, Pb, Mu, Mn are main the manufacturing; At last, be that three cavitys are established cooling medium inlet, outlet respectively, reacting material inlet, outlet; Like this, when the work of this device, reaction mass contacts with catalysis fin on the heat exchanging pipe and reacts; The catalysis fin is in catalytic reaction; Heat of reaction is in time removed, and heat exchanging pipe is given in conduction, and cooling medium is from being provided with two ends cooling medium storage chamber turnover; The heat exchanging pipe of flowing through will react unnecessary heat and take away.

The present invention can be very effective, and controllably some high exothermic reactions of catalysis of steady.

Description of drawings:

Fig. 1 is heat exchanging pipe according to the invention and catalysis fin structure sketch map;

Fig. 2 is a shell and tube heat transfer reactor cross-sectional view according to the invention;

Wherein: (1) tank body, (2) tube sheet, (3) heat exchanging pipe, (4) catalysis fin, (5) cooling medium storage chamber, (6) reaction chamber, (7) cooling medium is imported and exported, and (8) reaction mass is imported and exported, (9) tank body support.

The specific embodiment:

Like Fig. 1., shown in 2, at first, establish two tube sheets (2), intensive perforate on two tube sheets (2), and between two tube sheets (2), establish metal tube, as heat exchanging pipe (3), heat exchanging pipe (3) port is connected with tube sheet (2) perforate; Simultaneously, tube sheet (2) and tubulation (3) peripheral hardware metal can (1) like this, form three cavitys said tank body (1) in, i.e. two cooling medium storage chambers in two ends (5), and a centre reaction chamber (6) just has a large amount of heat exchanging pipes (3) in the said reaction chamber (6); On said heat exchanging pipe (3), establish catalysis fin (4), said catalysis fin (4) by the catalyst metals element as: Fe, Cu, Pb, Mu, Mn are main the manufacturing; At last, be three cavitys promptly: two cooling medium storage chambers (5), a reaction chamber (6) are established cooling medium respectively and are imported and exported (7), and reaction mass is imported and exported (8).
