Abstract
The utility model discloses an air cleaning system of a boiler, which comprises a boiler, wherein the boiler is communicated with a preheater through a flue gas pipeline; the preheater is provided with a preheater water inlet pipe and a preheater water outlet pipe; the flue gas pipeline is communicated with a cavity of the preheater; the water inlet pipe and the water outlet pipe are communicated with a preheating pipe in the preheater; and the preheater water inlet pipe is communicated with a boiler water inlet pipe. By utilizing the technical scheme, the air cleaning system of a boiler has the advantages that an original vertical preheater is replaced with a transverse preheater, accordingly flue gas produced by the boiler is exhausted through the cavity of the preheater, the flue gas flows outside the preheating pipe, so that the problems of clogging and difficult cleaning of the pipe are resolved, corrosion to equipment is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to boiler air cleaning unit in a kind of power plant.
Background technology
The original boiler cleaning system of power plant is that the cigarette vapour that boiler is discharged enters air preheater by cigarette steam pipe road, and air preheater all is vertical.Flue gas is discharged by preheating pipe, the vertical air preheater in use, because flue gas is walked in the pipe, and chemical substances such as the sulphur that contains in the coke-stove gas, naphthalene, after the boiler internal combustion, along with flue gas arrives preheater, and be cooled to solid matter, and stop up air preheater, be difficult to cleaning, preheater there is very big corrosiveness, shortens service life of equipment.
The utility model content
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of boiler air cleaning system is provided.
The technical solution of the utility model is:
A kind of boiler air cleaning system, comprise boiler, boiler is by flue and preheater UNICOM, and preheater is provided with preheater water inlet pipe and preheater outlet pipe, the cavity UNICOM of described flue and preheater, the economizer bank UNICOM in the water inlet pipe of preheater and outlet pipe and the preheater.
Above-mentioned boiler air cleaning system, described preheater outlet pipe and boiler water inlet pipe UNICOM.
Adopt technique scheme, the utility model has following advantage: change original vertical preheater into the horizontal type preheater, the flue gas that comes out from boiler is discharged by the cavity of preheater like this, flue gas is walked outside the economizer bank, a difficult problem that solved the pipe obstruction, is difficult to clear up, reduced corrosion, prolonged service life equipment.
Description of drawings
Fig. 1 is a conventional utility boiler cleaning system structural representation;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
A kind of boiler air cleaning system as shown in Figure 2, comprise boiler 1, boiler is provided with steam pipe 5, boiler 1 is by flue 4 and preheater 7 UNICOMs, preheater is provided with preheater water inlet pipe 6 and preheater outlet pipe 3, the cavity UNICOM of described flue 4 and preheater 7, and flue gas is discharged from discharge pipe 9 by preheater, economizer bank 8 UNICOMs in the water inlet pipe of preheater and outlet pipe and the preheater, preheater outlet pipe and boiler water inlet pipe 2 UNICOMs.
Claims (2)
1. boiler air cleaning system, comprise boiler, boiler is by flue (4) and preheater (7) UNICOM, preheater is provided with preheater water inlet pipe (6) and preheater outlet pipe (3), it is characterized in that: the cavity UNICOM of described flue (4) and preheater (7), economizer bank (8) UNICOM in the water inlet pipe of preheater and outlet pipe and the preheater.
