High temperature resistant feed nozzle

Abstract

The invention relates to a high temperature-resistant feeding nozzle. Present nozzles generally use external cooling type structures, it means that the nozzle is cooled through an outer jacket or cooling pipe coil mode, and the mode would generate a high temperature in the nozzle. The high temperature-resistant feeding nozzle comprises a nozzle (1), the nozzle is connected with a connecting flange (2), the connecting flange is respectively connected with an outer jacket cooling water inlet pipeline (3), an outer oxygen inlet pipeline (4), a nozzle head cooling water inlet pipeline (5), a nozzle head cooling water outlet pipeline (19) and an outer jacket cooling water outlet pipeline (10), the outer jacket cooling water outlet pipeline is connected with a material inlet pipeline (9) through the connecting flange, the material inlet pipeline is respectively connected with an inner cooling water inlet pipeline (8) and an inner cooling water outlet pipeline (6) through the connecting flange, and the inner cooling water outlet pipeline is connected with a central oxygen inlet pipeline (7). The high temperature-resistant feeding nozzle is good in cooling and heat dissipating performance.

Description

[0001] Technical field: [0002] The invention relates to a high-temperature-resistant feeding nozzle, which is suitable for the field of chemical energy where various types of oxygen and materials are simultaneously supplied through the nozzle. [0003] Background technique: [0004] Nozzles are very commonly used components in the chemical and energy fields. They are used to inject materials and combustion oxidizers into gasifiers or furnaces for combustion. Although the nozzle is a relatively small part in a chemical or energy system, it plays a key role in the stability, long-term and full-load operation of the system. [0005] The current nozzle generally adopts an external cooling structure, that is, the nozzle is cooled by means of an outer jacket or a cooling coil, and there is no cooling water channel inside the nozzle. Such a structure is relatively simple, but since there is only cooling water on the outside of the nozzle to dissipate heat, the temperature inside th...

Problems solved by technology

However, due to the damage of the nozzle, it needs to be stopped frequently for replacement. Therefore, in order to maintain normal production, the current common solution in all factories is to use spare equipment, which leads to a huge increase in equipment investment.
