Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of continuous row heat mass recovery, in particular to a steam injection and reuse device. BACKGROUND

[0002] Boiler blowdown is one of the losses in the operation of the boiler, in order to control the quality of the boiler water and steam, the boiler must be continuously blowdown, also known as surface blowdown, which requires continuously discharging part of the boiler water from the part with the highest salt and alkali concentration to reduce the salt, alkali and silica content in the boiler water and the content of slag in the suspended state. The waste heat recovery device is widely used. The adsorption filter element made of high-tech purification technology and composite nanomaterials can filter the steam and the adsorption rate of phosphates and silicon dioxide can reach more than 97%, and clean high-grade steam is introduced back to the steam supply pipeline to supply the downstream. However, the steam injection device will generate noise during use, which will cause the nozzle to vibrate, and long-term use will easily cause the nozzle to deform and be damaged, so the nozzle needs to be additionally reinforced to improve its stability.
