Problems solved by technology

Due to the different stacking methods, the flow resistance of the material in each tube is different, so each tube of the tube bundle reactor will have a different reaction time due to the difference in pressure loss, resulting in a reaction The quality of the product is significantly reduced
[0012] In order to avoid the above disadvantages, after the feeding action is completed in the automatic feeding mode, manual adjustment is usually required. This method takes a lot of time like manual feeding, or it is not adjusted manually, but must accept the disadvantage of poor quality reaction products

Embodiment Construction

[0035] The feeding device 10 shown in FIG. 1 has a frame 12 , and the function of this frame 12 is to carry a batching box unit 18 composed of a plurality of batching boxes 14 . The discharge end of the batching box 14 is provided with downcomers 24, and these downcomers 24 stop above the tubes of the tube bundle reactor as shown in FIG. 5 . The diameter of the downcomer 24 is slightly smaller than the diameter of the tubes of the tube bundle reactor.

[0036] The width of the distribution box 14 approximately corresponds to the width of the downcomer. For example, 20 batching boxes 14 are arranged side by side. Of course, the number of batching boxes can be changed in a large range according to the needs of the feed. The discharge end of each batching box has a discharge lip 64 extending into the discharge channel 20 of the batching box like an apron. Via the support plate 22 , each discharge lip 64 is adjustably supported within the discharge channel 20 .

[0037] The two...

Abstract

The invention relates to a feeding device for bundled tube reactors comprising a plurality of dosing chambers which are fillable with a filling material such as, for example, a catalytically coated carrier material. Each dosing chamber is extended by a down pipe or by another feeding device which make it possible to fill the tube of the bundled tube reactor. Said invention is characterised in that said dosing chambers are fillable by means of pre-chambers which are combined in an exchangeable pre-chamber unit.

Description

technical field [0001] The invention relates to a feeding device for a tube bundle reactor according to the preamble of claim 1 . Background technique [0002] Feeding to a tube bundle reactor usually requires the dumping of granular solids into the tubes of the tube bundle reactor. It has long been known that, for feeding purposes, tube-bundle reactors preferably have a number of tubes parallel to each other from the point of view of mechanical construction. The tube-bundle reactor proposed in US Patent No. USP2070868 is an example of such a tube-bundle reactor. In this US patent it is indicated that as far as possible the material to be poured into the tubes has the same flow rate in these tubes which are parallel to each other. In order to obtain acceptable reaction results. The feed should be as uniform as possible. In order to achieve the purpose of uniform feeding, automatic feeding (for example, patent USP3913806) must be adjusted manually afterwards. If possible...
