Problems solved by technology

The generation rate of the oxidation rate largely depends on the uniformity of the gas passing through the catalyst bed. Most of the existing spargers have simple structures, so that a large amount of unoxidized ammonia cannot be effectively catalyzed in places with high concentrations, which affects the nitrogen oxides. production rate, so it is necessary to provide an ammonia oxidation furnace distributor that can effectively increase the production rate of nitrogen oxides

Abstract

The invention discloses an ammonia oxidation furnace distributor with a double-circulation air entraining device. A feed port upper base is mounted at the lower end of a feed port; a feed port lower base is mounted at the lower end of the feed port upper base; a main material channel is mounted at the lower end of the feed port lower base; the main material channel is mounted in a main material pipe sleeve and extends into an outer hearth wall and is divided into an outer channel and an inner channel at the tail end away from the feed port lower base; the inner channel extends to the center of the outer hearth wall; an inner hearth is formed in an annular structure formed by the inner channel; the outer channel is distributed along the outer hearth wall; multiple outer spray heads are mounted on the side of the outer channel, close to the inner hearth; multiple inner spray heads are mounted on the side of the inner channel, close to the outer channel; and an outer hearth is formed between the outer channel and the inner channel. The ammonia oxidation furnace distributor disclosed by the invention has the advantages of high yield of nitrogen oxide and low energy consumption and effectively increases the yield of nitric acid.

Description

technical field [0001] The invention relates to the field, in particular to an ammonia oxidation furnace distributor with a double circulation gas filling device. Background technique [0002] The ammonia oxidation furnace is the key equipment for the production of nitric acid. The ammonia-oxygen mixed gas produces nitrogen oxide gas under the action of the catalyst, and then reacts with water to form nitric acid. The generation rate of the oxidation rate largely depends on the uniformity of the gas passing through the catalyst bed. Most of the existing spargers have simple structures, so that a large amount of unoxidized ammonia cannot be effectively catalyzed in places with high concentrations, which affects the nitrogen oxides. Therefore, it is necessary to provide an ammonia oxidation furnace distributor that can effectively improve the yield of nitrogen oxides. Contents of the invention [0003] In view of the above problems, the present invention provides an ammonia...
