The specific embodiment
Referring to Fig. 1 ~ 2, Fig. 1 is the boiler dedicated outside drawing of the utility model combustion carbon black tail gas.Fig. 2 is the boiler dedicated structural representation of the utility model combustion carbon black tail gas.By Fig. 1 and Fig. 2 as can be seen, the utility model combustion carbon black tail gas is boiler dedicated, comprise boiler body, economizer 5 and air preheater 6 three parts, the boiler body overall structure adopts two drum longitudinal " D " type arrangements, comprise upper drum 2, lower drum 3, convection bank 4 and burner hearth 1, convection bank 4 is arranged between upper drum 2 and the lower drum 3, the burner hearth 1 that the right side of upper drum 2 and lower drum 3 is made up of full film type wall, burner 7 places burner hearth 1 the place ahead, economizer 5 and air preheater 6 are arranged in the left side of boiler body, and air preheater 6 is arranged in the rear of economizer 5.
Described burner hearth 1 comprises left membrane wall, right membrane wall, back membrane wall, upper collecting chamber and next part case, left side membrane wall directly links to each other with lower drum 3 with upper drum 2 with right membrane wall, back membrane wall is compiled by upper collecting chamber and next part case, and upper collecting chamber links to each other with upper drum 2, and the next part case links to each other with lower drum 3.
Described air preheater 6 preferably adopts tube plate structure, and the flue gas trend adopts stagger arrangement to arrange for pipe outer stroke, stroke in the air hose, smoke pipe, as Fig. 3.
Described boiler body adopts the full film type wall sealing, realizes pressurized firing.
Operation principle:
One, burning
From the composition of carbon black tail gas as can be seen, its flammable composition is less, calorific capacity is very low, its actual ignition temperature has theoretical temperature combustion lower (~ 1100 ℃) simultaneously about 700 ℃, combustion flame is short, the flame kernel temperature is low, chemical reaction velocity is slow, is difficult for tempering, but easily takes off characteristics such as fire.Catching fire with steady combustion is to solve the key link that carbon black tail gas burns, thereby, the design of burner, palpus satisfies following the requirement:
(1) can organize tail gas to mix, and keep certain concentration level with the good of air; Strengthen mixing and disturbance, make gaseous mixture can be heated to ignition temperature rapidly.
(2) improve the temperature levels of combustion zone as far as possible, guarantee the timely heating isothermal of air-flow.
(3) rationalization's tail gas and Air mixing input to eliminate the combustion flame instability, pulsation occurs and to take off fiery problem, guarantees that burning continues safety and carries out.
(4) higher hot blast temperature helps catching fire and steady combustion of tail gas.
(5) enough combustion space and burning the time guarantees the efficiency of combustion of tail gas.
Two, air and gas system flow process
The flue gas that burner 7 burning backs produce passes through burner hearth 1, convection bank 4, economizer 5, air preheater 6 successively, drops to about 150 ℃ and enters atmosphere.
Normal temperature air enters air preheater 6 through air blast, and air preheater 6 is heated to about 100 ℃, enters burner 7, mixes combustion with fuel gas, as Fig. 4.
Three, boiler circuit flow process
Boiler circuit is a Natural Circulation, and carbonated drink utilizes density contrast to circulate in boiler.Boiler feedwater is introduced into economizer 5, absorbs the heat in the tail flue gas, obtains heating, enters upper drum 2; Water in the upper drum 2 enters lower drum 3 from the convection bank 4 of the weak part that is heated, and water absorbs the part heat in the flue gas, obtains heating; The water that enters lower drum 3 further heating in the convection bank 4 of the strong part of being heated and left membrane wall, right membrane wall, back membrane wall becomes steam water interface; Steam water interface separates in upper drum 2, and water is proceeded with cocycle, and saturated vapor feeds to the external world by venthole, as Fig. 5.
