Description
Technical field
The present invention relates to a kind of coal furnace, particularly about a kind of gas-fired direct burning furnace that in washing powder is produced, uses.
Background technology
The heating boiler that uses in the granulating working procedure of general production washing powder is fuel oil or gas fired-boiler, and its equipment price is higher, and running cost is also high, but also has hidden danger.And general coal firing boiler since the gaseous combustion chamber the position is set and structure unreasonable, on the one hand secondary combustion is abundant inadequately, the dust content in the flue gas is higher on the other hand, and temperature is wayward constant, therefore seldom is used to this type of operation.Yet along with the scarcity and the price of natural energy source constantly raises, how reducing the production cost of washing powder, environment is not polluted again, is the problem that the applicant studies.
Summary of the invention
The purpose of this invention is to provide a kind of gas-fired direct burning furnace that is used for washing powder production with the existing fuel-firing gas-firing stove of coal furnace replacement.
For achieving the above object, the present invention takes following technical scheme: a kind of gas-fired direct burning furnace that is used for washing powder production, it comprises: one builds the stove that forms by laying bricks or stones by shaped steel and brick mix structure, and described stove is divided into combustion chamber, ash discharge chamber, gaseous combustion chamber and hot gas path; The front portion of described combustion chamber has been arranged side by side two stoking fire doors, and described combustion chamber inner outlet is taper and shrinks; The bottom of described combustion chamber is separated by fire grate and described ash discharge chamber, and described ash discharge chamber is provided with two ash discharge air doors; After the taper outlet of described gaseous combustion chamber and described combustion chamber is connected, is the flaring shape of recessed bucket shape, and shrinks the venting port in the top, the foot of described gaseous combustion chamber is provided with ash output hole; The import of described hot gas path is connected with the venting port of described gaseous combustion chamber, and is the crooked upwards setting of serpentine, is provided with temperature sensor in the described combustion chamber, and described combustion chamber is outside equipped with temperature indicator.
The ash discharge air door of described ash discharge chamber is two symmetric vertical hinged doors.
Described hot gas path has the bending of two tangent lines and 45 ° of angles of level at least.
The present invention is owing to take above technical scheme, and it has the following advantages: 1, to adopt hard coal be that the coal-fired furnace kiln of fuel is the heat supply of washing powder granulating working procedure owing to be provided with one in the present invention, so equipment and running cost all descend significantly.2, the present invention is owing to be arranged to the taper collapsed shape with combustion chamber inner outlet place, and the gaseous combustion chamber is arranged to the diverging shape of recessed bucket shape, therefore when fire coal after combustion chambers burn, flue gas can be under the process of supercharging or decompression, in the gaseous combustion chamber, the coal dust in the flue gas is carried out secondary combustion more fully, and make dust sedimentation in the gaseous combustion chamber of after-flame.3, the present invention is owing to be arranged to serpentine with heat donor passage, therefore can make enter heat donor passage hot flue gas further with the collision of channel wall in, make the further sedimentation of dust particle in the flue gas, thereby make the hot gas dustiness that enters the washing powder granulating working procedure extremely low, can not pollute ambient air.4, therefore the present invention can be the combustion chamber stoking owing to be provided with two stoking fire doors in turn, and reduction is to the interference of whole temperature of combustion, can also prevent that the inadequate flue gas of burning that stoking moment causes from entering the gaseous combustion chamber by two half burned flames.5, the present invention is owing to be provided with two ash discharge air doors in ash discharge chamber, therefore when being used for ash discharge, can be used to the combustion chamber air feed, be arranged to symmetric vertical hinged door especially, not only ash discharge is easy, and can be by number of opening the door and the size of opening the door, the direction and the size that realize regulating the air feed that opens the door.The present invention is rational in infrastructure, the thermo-efficiency height, and coal burning is abundant, and the hot gas of generation is pure, has good environment protecting, can match in excellence or beauty with fuel oil, gas fired-boiler, is widely used in the various heat supply device of air, particularly produces in the prilling granulator of washing powder.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes: one builds the stove that forms by laying bricks or stones by shaped steel and brick mix structure, and stove is divided into combustion chamber 1, ash discharge chamber 2, gaseous combustion chamber 3 and hot gas path 4.1 front portion has been arranged side by side two stoking fire doors 11 in the combustion chamber, and combustion chamber 1 inner outlet is taper and shrinks; 1 bottom is provided with a fire grate 12 in the combustion chamber, and the bottom of fire grate 12 is ash discharge chamber 2.Being provided with two ash discharge air doors, 21, two ash discharge air doors 21 in ash discharge chamber 2 front portions can be a symmetrically arranged vertical hinged door.Gaseous combustion chamber 3 is arranged on the rear portion of combustion chamber 1, and is connected with the taper outlet of combustion chamber 1, and gaseous combustion chamber 3 is the flaring shape of recessed bucket shape, and shrinks the venting port 31 in the top, and the foot in gaseous combustion chamber 3 is provided with an ash output hole 32, is used for ash discharge.Import at hot gas path 4 is connected with the venting port 31 of gaseous combustion chamber 3, and be the crooked upwards setting of serpentine, be provided with temperature sensor in combustion chamber 1,1 is outside equipped with temperature indicator in the combustion chamber, and temperature sensor and indicating meter can be selected the off-the-shelf in the prior art for use.
In the foregoing description, hot gas path 4 is arranged to should have the bending of two tangent lines and 45 ° of angles of level at least in the structure that the serpentine bending makes progress, and the angle of tangent line and level can change to some extent.
When the present invention operates, two stoking fire doors of combustion chamber 1 can be the combustion chamber stoking in turn, can avoid influencing significantly whole fire box temperature like this, two ash discharge air doors 21 that are arranged on ash discharge chamber 2 can be regulated the size of opening the door according to the furnace temperature of indicating meter demonstration.After fire coal enters combustion chamber 1 burning, flue dust is after being shunk supercharging by taper, with higher velocity flow to gaseous combustion chamber 3, and the air-flow that enters gaseous combustion chamber 3 reduces pressure in the space that is the bucket shape flaring and reduce velocity of flow, thereby unburnt burning is fully burnt in gaseous combustion chamber 3, the hot gas dustiness that enters hot gas path 4 is greatly reduced.The hot gas that 3 venting ports 31 enter hot gas path 4 from the gaseous combustion chamber through repeatedly collision, can further improve dust-laying effect on the channel wall of serpentine.Be arranged on two ash discharge air doors of ash discharge chamber's 2 forward 21 and can be respectively applied for ash discharge with the ash output hole 32 that is arranged on gaseous combustion chamber sidepiece.
