Abstract
The utility model relates to a radial catalyst bed with a built-in central heat exchanger. The utility model mainly solves the technical problem that the gas resistance of the prior radial catalyst bet is high, which is not good for the indirect transfer of the heat of the outlet of the bed and the enlargement of a reactor. The radial catalyst bed is characterized in that the radial catalyst bed also comprises a cold/hot-gas central heat exchanger which is arranged in a radial catalyst bed basket. The utility model has the advantages that: since the cold/hot-gas central heat exchanger is arranged in the radial catalyst bed, the reacted gas can indirectly exchange heat with the cold gas in the tube, so that the gas temperature of the catalyst bed can be further reduced, and consequently, not only the heat of the outlet of the bed can be indirectly transferred, but also the gas resistance in the radial catalyst bed can be reduced.
Description
Technical field
The utility model relates to a kind of beds, relates to establish in a kind of the radially beds of center heat exchanger in particular, is mainly used in coal chemical technology.
Background technology
Radially beds is as the nucleus equipment of the reactor of synthetic ammonia, synthesizing methanol, synthesizing methane, but because existing radially beds is subject to the restriction of system pressure, can not adapt under low-pressure state and work, and, be unfavorable for the maximization that bed outlet heat moves heat and reactor indirectly because the air resistance of existing radially beds is higher.
Summary of the invention
Higher for the air resistance that solves existing radially beds, be unfavorable for the technical problems such as maximization that bed outlet heat moves heat and reactor indirectly; The utility model provides the radially beds of establishing the center heat exchanger in a kind of, and it not only can reduce the air resistance of beds, the maximization that also can make things convenient for the outlet heat of beds to move heat and reactor indirectly simultaneously.
For solving above technical problem, the technical scheme that the utility model is taked is to establish the radially beds of center heat exchanger in a kind of, it includes radially beds basket and cold air collecting chamber, it is characterized in that also including a hot and cold gas center heat exchanger, described hot and cold gas center heat exchanger is arranged on radially in the beds basket.
Further, described hot and cold gas center heat exchanger is by the dual-purpose pipe in center, upper support tube sheet, heat exchanger tube (bellows tube or pipe), floating tube sheet, the movable end socket in bottom, cone seal cylindrical shell, refrigerator pipe, reaction gas outlet, cold air distributing chamber form down.
Further, described radially beds basket is collected urceolus, gas collection inner core, hot gas collection chamber and carrying end socket by catalyst pressing plate, air admission hole, distribution of gas hole, distribution of gas tube, air chamber volume surrounding cylinder, distribution of gas cavity, the double-deck distribution grid that flows, gas collection hole, gas and is formed described air admission hole, the lower end of distribution of gas pore size distribution on the distribution of gas tube; Described distribution of gas cavity is arranged between distribution of gas tube and the air chamber volume surrounding cylinder.
Further, described cold air collecting chamber is made up of top pressure closure, sealing flange, airtight and watertight padding sub-assembly I, airtight and watertight padding sub-assembly II, end socket outer tube and airtight and watertight padding sub-assembly III.
The beneficial effects of the utility model are radially in the beds a hot and cold gas center heat exchanger to be set, adopt this structure, reacted gas and the interior cold air indirect heat exchange of pipe, guarantee further to reduce the gas temperature of beds, so not only can be beneficial to bed outlet heat and move heat indirectly and also can reduce the radially interior air resistance of beds.
