Abstract
The utility model discloses a vertical coal burning smokeless boiler, which comprises a boiler body composed of an inner and an outer boiler cylinders, wherein, a burning chamber is arranged under the inner boiler cylinder; a grate is arranged at the bottom of the burning chamber; longitudinal air inlet pipes are uniformly distributed on the inner boiler cylinder wall corresponding to the position of the burning chamber; air holes are uniformly distributed on the pipe wall of the air inlet pipe, which faces the interior of the burning chamber. A fire collecting arch and a smoke blocking arch which are convex towards the interior of the inner boiler cylinder are correspondingly and orderly arranged on the inner boiler cylinder wall from top to bottom above the air inlet pipe; a fire dividing arch is transversally arranged between the fire collecting arch and the smoke blocking arch; the bottom of a boiler body is provided with an air inlet chamber which is respectively communicated with the burning chamber and the air inlet pipe. Sufficient oxygen gas is blown into the burning chamber through the air inlet pipe, causing that coal can be sufficiently burned; substances of dust, etc. can be respectively blocked and the flow speed of smoke can be buffered by the smoke blocking arch and the fire dividing arch; the secondary flow reduction and dust removal of the smoke can be carried out through the fire collecting arch; thereby, the goal of smokeless discharge can be achieved. The utility model has the advantages of simple structure and low cost.
Description
Technical field
The utility model belongs to the improvement of vertical fire coal boiler structure, particularly the vertical fire coal less boiler.
Background technology
Problems such as the smoke discharge amount that the present various vertical fire coal boiler ubiquities that use cause because of structural design is unreasonable is big, coal burning is insufficient.Existing vertical fire coal boiler is directly rendered to coal in use on the fire bars of bottom, body of heater inner combustion chamber and is burnt, anoxic during coal burning, a large amount of black wood charcoal grains below 5 microns can not completing combustion, but along with flue gas is discharged, atmosphere is caused serious smoke contamination.Prior art rests on handles, replenishes combustion adjuvant or fuel is carried out deep processing in the coal burning process boiler exhaust gas, does the operating cost that has increased boiler greatly like this.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical fire coal less boiler, can make coal burning fully also can effectively reduce the discharging of flue dust.
The purpose of this utility model is achieved in that a kind of vertical fire coal less boiler, comprise the body of heater that constitutes by inside and outside stove tube, interior stove tube bottom is provided with the combustion chamber, the bottom, combustion chamber is provided with fire bars, body of heater is provided with the coal feeding hole that communicates with the combustion chamber, be provided with vertical blast pipe with uniform on the corresponding inner furnace tube wall in position, combustion chamber, the uniform eye of wind that is provided with on the tube wall of blast pipe in the combustion chamber; Be disposed with positioned opposite from top to bottom on the inner furnace tube wall of blast pipe top.And inwardly projecting inward poly-fire arch and the retaining cigarette of stove tube encircles, and is horizontally arranged with branch fire arch in the interior stove tube between poly-fire arch and retaining cigarette encircle, and bottom of furnace body is provided with the inlet air plenum that is connected with combustion chamber and blast pipe respectively.
The utility model in use, it is indoor that wind is blown into boiler combustion from blast pipe and interior stove tube bottom respectively through the inlet air plenum of bottom of furnace body, for the coal burning in the combustion chamber provides sufficient air, make coal be able to abundant burning, thereby eliminate because anoxic and the abundant black wood charcoal grain of after-flame.On the inner furnace tube wall above the blast pipe, be equipped with poly-fire arch from top to bottom successively, divide fire arch and retaining cigarette arch, make the discharge course of flue gas become tortuous, by retaining cigarette arch with divide the fire arch respectively the materials such as dust in the flue gas to be stopped and the flow velocity of flue gas is cushioned, by poly-fire arch flue gas is carried out secondary again and subtract the stream depositing dust, reach and reduce the purpose that flue dust is put.The utility model is simple in structure, low cost of manufacture, and dust removing effects is remarkable, is easy to promote.
