Mouth, the separator being arranged in drum inner cavity.Water supply mouth structure includes that one end passes through dome shell and is inserted into drum inner cavity
Tube body, tube body includes the annular that tube wall, center outwardly protrude to aquaporin, from the outside of tube wall and be connected with dome shell
Boss, the inside of tube wall offer the annular groove being arranged around center to aquaporin, one end and the drum inner cavity phase of the annular groove
Connection.
Further, the other end of annular groove extends to the top of tube wall.
Further, the middle part of tube wall is arranged in boss.
Further, through-hole is offered on dome shell, boss is located in the through-hole and is connected with the hole wall of through-hole.
Further, the outer rim of boss and the hole wall of through-hole mutually weld.
Further, the decontamination apparatus for liquid-covered dirt in drum inner cavity to be discharged is provided in drum inner cavity, it should
Decontamination apparatus includes transverse tube, the multiple dirt inlet pipes being connected on transverse tube, one end is connected with transverse tube and the other end stretches out drum
The dirt comb of shell.
Further, the lower end of dirt inlet pipe is connected with transverse tube, and upper end is located at the liquid level of liquid in drum inner cavity
Below.
Further, the outlet end of separator is connected with steam (vapor) outlet.
Due to the adoption of the above technical scheme, the utility model is made after low stress structure for the drum of high-pressure boiler
Obtaining the stress at this reduces about 60%, greatly prolongs the service life of the equipment, improves the safety of equipment.
