Abstract
Fixed multiinjector soot blower of balanced draft boiler, it includes gooseneck valve (1), hollow shaft (2), bow -shaped splint (3), blowing pipe (4), gland packing (5), shower nozzle (6) and air valve (7), ring array opens and to have a set of square hole on the circumference of shower nozzle (6), and the square hole forms contained angle alpha with water flat line, and contained angle alpha be 15, and the end of giving vent to anger of shower nozzle (6) comprises a set of round hole, and just a set of round hole is to disperse with the axle center respectively and describes direction ring array, the utility model has the advantages that: compact structure, the on -the -spot installation of being convenient for, the shower nozzle adopts the multiinjector structure, and the nozzle direction all is the slope, and it is too big to avoid directly blowing local air current in the work, damages and is blown grey part, and the nozzle on the shower nozzle circumference can form rotatory air current when blowing, increase to blow grey effect.
Description
Technical field
The utility model product relates to balanced draft boiler soot blower field used, is specifically related to a kind of balanced draft boiler fixed multi-nozzle soot blower.
Background technology
At present, the large installation inconvenience of soot blower volume that existing balanced draft boiler is used, the nozzle structure of soot blower is single, blow grey effect undesirable, shower nozzle is directly easily caused over-blowing facing to blowing grey parts, damages and is blown parts, in blowing pipe backhaul, flue gas can be immersed in soot blower inside along with nozzle, corroded components.
Utility model content
The purpose of this utility model is exactly at present, the large installation inconvenience of soot blower volume that existing balanced draft boiler is used, the nozzle structure of soot blower is single, blow grey effect undesirable, shower nozzle is directly easily caused over-blowing facing to blowing grey parts, damages and is blown parts, in blowing pipe backhaul, flue gas can be immersed in soot blower inside along with nozzle, the deficiency of corroded components, and provides a kind of balanced draft boiler fixed multi-nozzle soot blower.
The utility model comprises gooseneck valve, hollow shaft, cambered plate, blowing pipe, stuffing box, shower nozzle and air valve, the side of gooseneck valve has valve mounting apertures, air valve is arranged in hole, cambered plate by support installing on gooseneck valve, hollow shaft communicates with the gas outlet of gooseneck valve through cambered plate, blowing pipe is communicated with the gas outlet of hollow shaft by stuffing box, shower nozzle is arranged on the outlet side of blowing pipe, the circumferentially annular array of described shower nozzle has a prescription hole, and square hole and horizontal line form angle α, angle α is 15 °, the outlet side of shower nozzle is made up of one group of circular hole, and one group of circular hole is divergent shape direction annular array with axle center respectively.
The utility model has the advantages that: compact conformation, be convenient to in-site installation, shower nozzle adopts multiinjector structure, and nozzle direction is all tilt, and avoids directly blowing local air flow in work excessive, damages and blown grey parts, shower nozzle nozzle circumferentially can form swirling eddy when blowing, and increases and blows grey effect.
accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A-A sectional view.
Detailed description of the invention
As Fig. 1, shown in 2, the utility model comprises gooseneck valve 1, hollow shaft 2, cambered plate 3, blowing pipe 4, stuffing box 5, shower nozzle 6 and air valve 7, the side of gooseneck valve 1 has valve mounting apertures, air valve 7 is arranged in hole, cambered plate 3 by support installing on gooseneck valve 1, hollow shaft 2 communicates with the gas outlet of gooseneck valve 1 through cambered plate 3, blowing pipe 4 is communicated by the gas outlet of stuffing box 5 with hollow shaft 2, shower nozzle 6 is arranged on the outlet side of blowing pipe 4, the circumferentially annular array of described shower nozzle 6 has a prescription hole, and square hole and horizontal line form angle α, angle α is 15 °, the outlet side of shower nozzle 6 is made up of one group of circular hole, and one group of circular hole is divergent shape direction annular array with axle center respectively.
Working method: during work, gases at high pressure spray from shower nozzle 6, when air-flow is by shower nozzle 6 one group of inclination square nozzle circumferentially, swirling eddy can be formed in boiler, make to blow grey better effects if, one group of divergent shape circular hole of shower nozzle 6 outlet side, the direction of each nozzle is different, that can strengthen shower nozzle blows grey area, and air-flow can not be focused on a place and cause over-blowing, damage boiler inner wall, at the end of blowing ash, air valve 7 be convenient to air enter in gooseneck valve and interior pipe resist flue gas immerse corrosion these parts, cambered plate 3 exists as bracing frame, the weight of blowing pipe 4 is avoided to cause distortion to gooseneck valve 1.
