Example Embodiment

[0078] 3 discloses an embodiment of a high-purity ammonia waste incineration system embodiment, which is mainly different from Embodiment 2, except 22, according to the conditions demand, finned tube heat exchanger 21 the flue gas and the exhaust fan 10 incinerators The outlet 8 is directly connected to the chimney through a flue. Compared with the high-purity waste ammonia incineration system described in Example 2, the corresponding incineration process reduces heat exchange and heat energy recovery, reduces input costs, and the other is basically the same, so it will not be repeated here.

[0079] A set of specific application test cases based on the high-purity waste ammonia incineration system described in Example 2 are given below:

[0080] Related parameters: waste ammonia concentration: 99.9%; waste ammonia maximum processing capacity: 70kg / h; auxiliary fuel: hydrogen; circulating liquid: ethylene glycol aqueous solution; maximum circulating fluid volume: 30 tons / h; ethylen...

Abstract

The invention discloses a high-purity waste ammonia gas incinerating system. A high-purity waste ammonia gas incinerating furnace, a combustion device, an ammonia gas pipeline, a combustion supportingair pipeline, a fuel pipeline, a heat exchange device, a smoke discharging draught fan and a control device are included. The high-purity waste ammonia gas incinerating furnace comprises a furnace body, a first gas inlet distribution device, a second gas inlet distribution device and a fire barrier. The first gas inlet distribution device is connected with the ammonia gas pipeline through an ammonia gas pipeline connector, and the second gas inlet distribution device is connected with the combustion supporting air pipeline through an air supplementing port. When fuel generates flames in a hearth through a flame nozzle of the combustion device, the first gas inlet distribution device is used for distributing guided-in ammonia gas on the flame peripheries for sufficient combustion, and thesecond gas inlet distribution device is used for axially spraying guided-in combustion supporting air so that an air wall can be formed on the flame peripheries. Furthermore, a corresponding high-purity waste ammonia gas incinerating furnace and a corresponding incinerating technology are disclosed. Through the high-purity waste ammonia gas incinerating system, furnace and technology, in the heating power incineration process, generation of nitric oxide can be controlled while high-purity waste ammonia gas is completely combusted.

Description

technical field [0001] The invention belongs to the field of incineration equipment, and in particular relates to an incinerator, system and process which can be used for waste ammonia treatment in the production process of high-purity ammonia. Background technique [0002] High-purity ammonia is an important chemical basic material, which is widely used in the research and production of electronics, chemical industry, metallurgy, energy and other industries. The purity requirement of electronic grade high-purity ammonia reaches 99.9999% (volume fraction). [0003] In the production process of high-purity ammonia, waste ammonia with a higher purity of 99.9% (volume fraction) is produced due to incomplete separation of impurities. Since ammonia gas is a harmful gas, it cannot be discharged directly, and it needs to be treated before being discharged. At present, the usual processing methods mainly include: 1) discharge the gas to the absorption tower to be absorbed by water...
