Description
Technical field
The utility model belongs to oxygen enrichment hydrogen manufacturing cyanic acid technical field, relates to a kind of device that is used for oxygen enrichment hydrogen manufacturing cyanic acid.
Background technology
The main method of producing prussic acid at present in the world has iS-One method, BMA method, Sha Wenni dry method, light oil cracking method etc.
IS-One method is a raw material with methane, ammonia and air, and platinum guaze is the synthetic prussic acid of catalyzer, but exists tail gas not recycle, and emptying is the shortcoming of contaminate environment again; The characteristics of BMA method are to make raw material with methane and ammonia, and platinum catalyst is distributed on the ceramic reaction tube, and raw material is through high-temperature catalytic reaction in the pipe; Reaction heat is supplied with by the outside; Heating temperature is up to 1400-1500 ℃, and the high temperature material of reactor drum is not easy to solve, and heat energy consumption is also very high; Light oil cracking method and Sha Wenni dry method are similar, are characterized in that with low-carbon alkanes such as ammonia and C1-C6 be raw material, adopt refinery coke (conductive particle) flowing bed reactor; Electrode is inserted in the thermopnore, and externally fed produces heat, keeps 1300～1600 ℃ of temperature of reaction; Electrisity consumption is very big; And the running period of its Reaktionsofen is short, and maintenance is frequent, and by product carbon is contaminate environment also.
In sum; In order to overcome the shortcoming of prior art; Researched and developed a kind of technology of oxygen enrichment legal system prussic acid; The air that is about to generally to use is at present done raw material and is changed oxygen-rich air into and do raw material, and oxygen-rich air can be joined air by making oxygen by air separation and produced, or carries gas behind the nitrogen by transformation absorption and allocate in the air and produce.Yet the device of existing hydrogen manufacturing cyanic acid all is not suitable for this technology.
Summary of the invention
The purpose of the utility model provides a kind of device that is used for oxygen enrichment hydrogen manufacturing cyanic acid.
The utility model is realized through following technical scheme:
A kind of device that is used for oxygen enrichment hydrogen manufacturing cyanic acid; Comprise the liquid ammonia storage tank, vaporizer, well heater, surge tank, ammonia absorbent charcoal adsorption tank, ammonia deep bed filter, mixing tank, preheater, quaternary gas mixer, spark arrester, the prussic acid reactor drum that connect successively; Wherein said mixing tank also is connected with the Sweet natural gas deep bed filter; The Sweet natural gas deep bed filter is connected with the Sweet natural gas absorbent charcoal adsorption tank; Described preheater also is connected with the air deep bed filter, and the air deep bed filter is connected with the transformation adsorber, and described quaternary gas mixer also is connected with vapour generator.
The liquefied ammonia that comes from liquid ammonia storage tank gets into the ammonia surge tank after getting into heater heats behind the liquefied ammonia vaporizer; The gas that comes out from the ammonia surge tank gets into the ammonia absorbent charcoal adsorption tank respectively and the ammonia deep bed filter carries out purifying treatment, and purified gas is sent into mixing tank; Getting into mixing tank after natural gas via Sweet natural gas absorbent charcoal adsorption tank and the Sweet natural gas deep bed filter purifying treatment mixes with the ammonia of purifying treatment; The incoming stock gas mixing of the gas preheater mixing preheating that the oxygen-rich air that comes from the transformation adsorber comes with mixing tank behind air pocket type filter cleaning; Gas mixture after the preheating gets into the quaternary gas mixer to be mixed with the steam that comes from vapour generator; Mixed quaternary gas gets into the prussic acid reactor drum at last through gas mixture deep bed filter, spark arrester, and tail gas send synthesis ammonia system.
The utility model is simple in structure, and easy handling has improved throughput, has reduced labour cost and production cost.
