Description
Technical field
The utility model is related to boiler technology field, and in particular to a kind of novel horizontal Pulverized Fuel Boiler Furnace soot blower.
Background technology
The body construction of existing pulverized coal fired boiler, the position according to burner is generally divided into following several structures：
First, at the top of boiler, flame vertical is downward, vertical, to be applicable the flame characteristics of burner, boiler design for burner arrangement
Height is very high, and operation, maintenance difficulty are very big, the capital expenditure added cost of boiler room.
2nd, in boiler bottom, upwards, vertical, lime-ash easily causes combustion to flame vertical to burner arrangement into burner
Burner failure or coking phenomenon, cause shutdown maintenance, and maintenance is difficult.
3rd, burner arrangement is horizontally disposed in front wall or side wall, horizontal arrangement, due to its simple structure, operation of combustors
Maintenance is convenient, with very big development space.But burner hearth is due to horizontally disposed, ash content free settling after coal dust firing is simultaneously gathered
In burner hearth, cause the pollution of heating surface or even produce coking phenomenon.
Because horizontal arrangement is for vertical, its boiler room construction investment is few, and boiler design is highly relatively low, day
Often operate, safeguard more convenient, therefore the structure type application of horizontal arrangement is wider.It is conventional for the burner hearth dust stratification of horizontal arrangement
Processing method be to set ash dropping hopper in the bottom of burner hearth, ash dropping hopper bottom connects the ash discharge system such as slag remover or storehouse pump, by machinery
Or the mode ash discharge of Geldart-D particle, complex structure, fault rate is high, and operational effect is poor, it is impossible to meet actually used needs.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of novel horizontal Pulverized Fuel Boiler Furnace
Soot blower.The utility model arranges compressed air ash discharging gear on burner hearth inner bottom surface, by compressed air regular purge, will
The ash for being deposited in burner hearth bottom is blown afloat, and the cleaner of afterbody, the interior not dust stratification of burner hearth are entered with flue gas.The utility model design is closed
Reason, simple structure is cheap for manufacturing cost, and fault rate is low, fixed by DCS control system logic controls using mode is automatically adjusted
Phase soot blowing, high degree of automation is simple to operate, reduces labor strength.
To achieve the above object, the utility model uses following technical proposals：A kind of novel horizontal Pulverized Fuel Boiler Furnace soot blowing
Device, it includes the burner hearth being made up of furnace wall cooling, and arrangement is provided with burner, the bottom of burner hearth on the front end face of the burner hearth
Distribution is provided with multiple first blowing pipes along the length direction of burner hearth on face, is distributed on each described first blowing pipe and is connected with
Multiple air cap devices, are provided with the second blowing pipe and the second blowing pipe along the width of burner hearth on the bottom surface of burner hearth front end and open up
Have multiple soot blowing stomatas, the inlet end of the first blowing pipe is connected with compressed air system, the inlet end of the second blowing pipe pass through into
Tracheae is connected with compressed air system, and the junction of the first blowing pipe and compressed air system, the second blowing pipe are empty with compression
The junction of gas system is each equipped with magnetic valve, and the control end of magnetic valve is connected by circuit with DCS control systems.
Preferably, the number of first blowing pipe is four, the number of second blowing pipe two.
The beneficial effects of the utility model are：
The utility model arranges compressed air ash discharging gear on burner hearth inner bottom surface, by compressed air regular purge, will
The ash for being deposited in burner hearth bottom is blown afloat, and the cleaner of afterbody, the interior not dust stratification of burner hearth are entered with flue gas.The utility model design is closed
Reason, simple structure is cheap for manufacturing cost, and fault rate is low, fixed by DCS control system logic controls using mode is automatically adjusted
Phase soot blowing, high degree of automation is simple to operate, reduces labor strength.
