Abstract
The invention relates to a spray head and a spray head manufacturing method, in particular to a high-temperature resistant soot blowing spray head for gasifying pulverized coal and a manufacturing method thereof. The spray head comprises a cylindrical spray head body. A central through hole is formed in the axial center of the spray head body. Circumferential holes communicated with the central hole are formed in the spray head body in the radial direction. Inclined holes communicated with the central hole are further formed in the spray head body. One to four circumferential holes with the central lines in the same circumference are used as one set. N sets of circumferential holes are formed in the spray head body. The value range of N is 1-30. The number of the inclined holes is M, and the value range of M is 1-10. The included angles alpha between the central lines of the inclined holes and the central axis of the spray head body are 35-60 degrees. The circumferential distance beta between every two adjacent circumferential holes in the same set of the circumferential holes is 40-60 degrees. The high-temperature resistant soot blowing spray head is made of solid round steel and is manufactured by forming the holes in the corresponding positions. The high-temperature resistant soot blowing spray head is capable of resisting high temperature, does not need to be cooled through water in the using process, and meanwhile solves the problem that a back blowing device fails to blow back due to the fact that back blowing air holes are prone to being blocked.
