Description
Technical field
The utility model relates to a kind of New-type boiler blast cap, belongs to boiler combustion device field.
Background technology
Wind cap for boiler is arranged on the aerofoil of fluidized-bed combustion boiler bottom of combustion chamber, inside communicates with bellows, purposes is transported in the siege bed of material by boiler air-supply, air required when meeting boiler, by controlling the size of air output, be that the siege bed of material remains fluid boiling state, make coal burning thorough.But the blast pipe on Wind cap for boiler is generally level, and such exhaust is easily washed into the Wind cap for boiler of periphery, cause damage.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of New-type boiler blast cap.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of New-type boiler blast cap, comprise blast pipe, blast cap outer cover and air vent, blast pipe is placed on the inside of blast cap outer cover, the upper end of blast pipe is provided with air vent, the inside of blast cap outer cover is provided with blast pipe, the air outlet internal sleeve of blast pipe has one end of snorkel, and the outside cover of the other end of snorkel has loose wind apparatus, and loose wind apparatus is provided with loose air holes.
The related content of technique scheme is explained as follows:
In such scheme, snorkel is hollow structure, and the outside of snorkel is provided with screw thread, and screw thread is engaged mutually with inside the air outlet of blast pipe, and screw thread is engaged mutually with the inner side of loose wind apparatus.
In such scheme, the shape of loose wind apparatus is six prisms, and each side of described loose wind apparatus is equipped with loose air holes, and loose wind apparatus inside is provided with loose wind passage, and loose wind passage is connected with loose air holes.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Because snorkel is connected by screw thread with loose wind apparatus respectively at blast pipe, convenient disassembly, loose wind apparatus is provided with 6 roads air holes of faling apart and is connected with loose wind passage, the boiler air-supply of level being released is dispersed into 6 different angle releasings, namely angle vertically upward, angle vertically downward, be the angle of 30 ° with horizontal direction and be the angle of-30 ° with horizontal direction, and, in use, there is the direction needing to avoid as operated, the loose air holes in this direction can be blocked.
