Description
Technical field:
The utility model relates to a kind of boiler, especially relates to the wet backwater pipe three backhaul coke boilers of a kind of vertical internal combustion.Belong to the heat transmission equipment technical field.
Background technology:
Make following, conventional coke boiler at the utility model the wet back of the body of vertical internal combustion fire tube three return-stroke types are arranged.Mainly there is following deficiency in it:
1, flue gas is walked tube side, and fire tube and flue gas contact area are little, and heat transfer coefficient is low.
2, the easy dust stratification obstruction of mouth is advanced in the fire tube end, and dust stratification is removed difficulty, and boiler operatiopn is safe and reliable poor.
3, fire tube is assemblied in the water spacer, can't keep in repair.
4, flue gas flow rate is fast in the fire tube, and is easy to wear to the brute force of washing away of fire tube, and service life is short.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of heat transfer efficiency height, deashing are convenient, the maintenance transposing is convenient, the wet backwater pipe three-pass boiler of vertical internal combustion long service life
The purpose of this utility model is achieved in that a kind of vertical internal combustion backwater pipe three backhaul coke boilers that wet, it comprises shell, flue, U type pin circle, base, fire grate, furnace grate tube, interior waterwall tube, outer waterwall tube, water inlet pipe, steam outlet pipe, following smoke-box and fume collecting chamber, described flue places in the shell, U type pin circle is connected in flue and shell lower end, shell, flue and U type pin circle constitute the water spacer, the water spacer places on the base, fire grate is horizontally placed on the base, furnace grate tube places the fire grate top, be distributed on the inboard wall of furnace face on the interior waterwall tubular axis, outer waterwall tube axially is distributed on the shell outside wall surface, water inlet pipe is arranged at shell shell wall bottom, be connected with the water spacer, the water spacer is connected with interior waterwall tube and outer waterwall tube respectively, and steam outlet pipe is connected in shell top, be connected with the water spacer, passage between water spacer and the base constitutes smoke-box down, and fume collecting chamber is positioned at outer waterwall tube top, and the inner chamber of interior waterwall tube constitutes first backhaul of flue gas; Constitute second backhaul of flue gas between interior waterwall tube and the inboard wall of furnace; Constitute the 3rd backhaul of flue gas between shell outer wall and the outer waterwall tube, first backhaul is connected with the top of second backhaul by interior waterwall tube, and second backhaul is connected with the 3rd backhaul by following smoke-box, and the 3rd backhaul is connected with fume collecting chamber.
Flue gas by first backhaul through interior waterwall tube overhead stream through second backhaul, flow to the 3rd backhaul through following smoke-box again, after fume collecting chamber and after dust removal process, discharging by chimney.
Waterwall tube and outer waterwall tube in water is entered by water spacer bottom by water inlet pipe, the water vapour that the heating back produces is discharged by the steam outlet pipe at water spacer top.
Compare with the traditional wet back of the body of vertical internal combustion fire tube three-pass boiler coke, the utlity model has following advantage:
1, water is walked tube side, and water pipe has adopted extended surface tube, and water pipe and flue gas contact area improve greatly, have strengthened heat transfer, realizes efficient burning.
2, adopt water pipe to solve fire tube end dust stratification, and deashing is convenient, can guarantees the long-term efficient operation of boiler, safe and reliable.
3, water pipe is installed in outside the water spacer, and the maintenance transposing is convenient.
4, avoided flue gas that the high speed of tube bank is washed away long service life.
