Abstract
The invention relates to the technical field of incineration boilers for burning household garbage, in particular to a fire grate cooling system of a garbage incinerator. By means of the fire grate cooling system of the garbage incinerator, the phenomena of excessively high temperature of the furnace wall at a fire grate and coking of the furnace wall can be effectively avoided, and the service life of refractory bricks is prolonged. The fire grate cooling system of the garbage incinerator comprises a downcomer collection box, a fire grate cooling system lower collection box and a fire grate cooling system upper collection box which are arranged in sequence in the arranging direction of the incinerator fire grate. The downcomer collection box and the fire grate cooling system lower collection box are connected through first connecting pipes, the fire grate cooling system lower collection box and the fire grate cooling system upper collection box are connected through a fire grate face stepped pipe, and the fire grate face stepped pipe is arranged on the incinerator fire grate.
Description
Technical field
The present invention relates to a kind of technical field using Domestic refuse incinerator, be specially a kind of garbage incinerator grates cooling system.
Background technology
Current is in the garbage burning boiler of domestic waste at fuel, the basic technique adopting fire grate combustion refuse.Because temperature in combustion process is very high, be approximately 800 DEG C ~ 1000 DEG C, therefore combustion zone furnace wall meeting coking because localized hyperthermia burns, coking material is attached on furnace wall and also day by day increases, and this phenomenon can shorten the service life of refractory brick.
Summary of the invention
In order to solve the problem, the invention provides a kind of garbage incinerator grates cooling system, it effectively can solve the phenomenon of coking on the too high and furnace wall of fire grate place temperature of furnace wall, extends refractory brick service life.
Its technical scheme is such: a kind of garbage incinerator grates cooling system, it is characterized in that, it comprises and moves towards along incineration furnace grate down-comer header, fire grate cooling system lower header, the fire grate cooling system upper collecting chamber arranged in turn, be connected by the first tube connector between described down-comer header with described fire grate cooling system lower header, connected by grate surface ladder pipe between described fire grate cooling system lower header, fire grate cooling system upper collecting chamber, described grate surface ladder pipe is arranged at above described incineration furnace grate.
It is further characterized in that, described fire grate cooling system upper collecting chamber connects burner hearth side water wall lower header by the second tube connector;
Described first tube connector, the second tube connector comprise two respectively.
After adopting structure of the present invention, grate surface ladder pipe is arranged at above incineration furnace grate, saturation water absorbs through out-of-date the radiant heat being radiated furnace wall, thus reduce the temperature of incinerator furnace wall, thus play the effect preventing the furnace wall coking of high-temp combustion region, extend the service life of refractory brick, that saves refractory brick reprocesses expense, good economy performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic flow sheet of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of garbage incinerator grates cooling system, it comprises and moves towards along incineration furnace grate 7 down-comer header 1, fire grate cooling system lower header 2, the fire grate cooling system upper collecting chamber 3 arranged in turn, be connected by two first tube connectors 4 between down-comer header 1 with fire grate cooling system lower header 2, connected by grate surface ladder pipe 5 between fire grate cooling system lower header 2, fire grate cooling system upper collecting chamber 3, grate surface ladder pipe 5 is arranged at above incineration furnace grate 7.
Fire grate cooling system upper collecting chamber 3 connects burner hearth side water wall lower header 9 by two second tube connectors 8, can increase the heating surface area of burner hearth part like this, improves boiler output.
See described in Fig. 2, the first tube connector 4 that saturation water 6 is drawn from down-comer header 1 by two, enter fire grate cooling system lower header 2, saturated flow is through being arranged in the grate surface ladder pipe 5 above incineration furnace grate, and saturation water can sponge the heat that a part of fire grate segment gives off in the process; After completing heat absorption, saturation water imports cooling system upper collecting chamber 3, then introduces burner hearth side water wall lower header 9 by two second tube connectors 8, completes circulation.
