Internal component gas distributor of converter

Abstract

The invention relates to a gas distributor of synthesis tower internals, which comprises a plurality of gas introducing tubes and gas guide tubes which are vertically arranged and a plurality of layers of coil tubes arranged radially. The gas distributor is characterized in that a perforated plate is horizontally arranged above gas inlets of all gas introducing tubes respectively, and a gas outlet of each gas introducing tube is communicated with one straight tube arranged radially. Compared with the prior art, the invention ensures that gas in a gas collecting chamber realizes primary uniform stream distribution through the perforated plate and realizes secondary uniform stream distribution under the action of the perforated plate in the straight tube, thereby laying a foundation for ensuring the uniformity of reaction gas and the uniform distribution in a basket. In addition, as the straight tube is arranged radially, the coil tubes arranged radially can be connected with the gas introducing tubes through the gas guide tubes in an approaching mode, and the difficult connection between ring tubes and the plurality of the coil tubes of the prior large-diameter tower internals is solved.

Description

【Technical field】 [0001] The invention relates to a chemical synthesis reaction device, in particular to a gas distributor for synthesis tower internals. 【Background technique】 [0002] The gas distributor is an important part of the synthesis tower internals. Its function is to improve the uniformity of the reaction gas from the gas collection chamber to the coil, to make the reaction gas evenly distributed in the catalyst basket, and to make the temperature difference of the same bed less than ± 3°C, to achieve the purpose of improving operating conditions, increasing catalyst utilization, increasing product output and improving economic benefits. The Chinese Patent No. 032293291 is "A Gas Distributor for Synthetic Tower Internals". On the basis of the previous distributor structure, it adds a ring pipe connected to the air induction pipe, and the two ends are respectively connected to the ring pipe and the upper outer coil. , The gas guide pipe connected to the upper inn...

Problems solved by technology

[0003] However, with the continuous enlargement of chemical synthesis equipment, it is difficult for existing gas distributors to adapt to this. For large synthesis tower internals with a diameter greater than 1200mm, there are the following deficiencies: 1. After the inner diameter of the tower increases , the gas flowing downward from the gas collection chamber will have a bias flow phenomenon, which will affect the uniformity of the gas reaction, and the temperature difference is difficult to meet the requirements

2. Since the large-diameter tower needs to install radially arranged multi-layer coils in the inner cavity of the tower, the coils are stacked on top of each other. For example, the current bleed pipe is connected to the ring pipe, and the ring pipe passes through a layer. The structure in which one layer of air ducts is connected with layers of coiled pipes not only makes it very difficult to connect the coiled pipes with the ring pipes in a crowded space, but also is not conducive to the uniform flow of gas.
