Abstract
The utility model discloses a water-coal-slurry burner nozzle, which comprises a shell body, a plurality of turbulent pipes arranged in an inner cavity of the shell body and a water-coal-slurry conveying pipe; one end of the shell body is connected with the water-coal-slurry conveying pipe, the turbulent pipes are communicated with the furnace cavity of a conducting oil furnace through the other end of the shell body. The shell body is provided with an air inlet, the inner cavity of the shell body is communicated with the outside air through the air inlet. The shell body comprises a separatedfirst shell body and a separated second shell body; the air inlet is arranged at the second shell body; both ends of the second shell body are respectively connected with the first shell body and screw threads of the water-coal-slurry conveying pipe. The turbulent pipes are fixedly connected with the inner cavity of the shell body through a supporting plate. The water-coal-slurry burner nozzle isnot easy to damage during the burning and atomization of the water-coal-slurry; the service life is long; the nozzle can be widely applied to the water-coal-slurry conducting oil furnace.
Description
Technical field
The utility model relates to a kind of parts of water-coal-slurry heat-conducting oil furnace, is meant that specifically the water-coal-slurry with flow-like is entering the water-coal-slurry torch firing nozzle that atomizes before the heat-conducting oil furnace burner hearth burns.
Background technology
As everyone knows, heat-conducting oil furnace is in fields such as food, chemical industry, in process such as heating, dry to material or be softening, be used widely, it is a fuel with the coal generally, and coal combustion not to the utmost, and efficiency of combustion is low, and in burning, produce a large amount of flue gas and dust, and carry a large amount of coal ash particles, sulfur dioxide (SO2) emissions in atmosphere, and pollute to environment, that gives people healthyly brings harm; For solving the big problem of the coal-fired produced pollution and energy consumption, people adopt combusting coal water slurry to replace fire coal, water-coal-slurry is a kind of with in coal, water, the portions additive adding grinding machine, after grinding, become the same coal based fluid fuel that can flow of a kind of similar oil, water-coal-slurry is burnt more abundant in stove, and efficiency of combustion is higher, and the flue gas and the dust that are produced are less, environmental protection and energy-saving benefit are remarkable, therefore more and more obtain being extensive use of of people; But because the water-coal-slurry torch firing nozzle of existing water-coal-slurry heat-conducting oil furnace is made of a little jet orifice plate, because the spray orifice aperture is little, thereby water-coal-slurry flow velocity when this hole is very fast, make the spray orifice serious wear, the jet orifice plate life-span is shorter, and all must change every month, made by carbide alloy owing to jet orifice plate again, its price is higher, has therefore increased maintenance and production cost.
The utility model content
The water-coal-slurry torch firing nozzle not fragile when the technical problems to be solved in the utility model provides the atomizing of a kind of water-coal-slurry torch firing, that service life is long.
For solving the problems of the technologies described above, the utility model adopts so a kind of water-coal-slurry torch firing nozzle, this nozzle comprises housing, place the some turbulated tubes and the water-coal-slurry carrier pipe of described housing inner chamber, one end of described housing links to each other with the water-coal-slurry carrier pipe, and described turbulated tube is connected with described heat-conducting oil furnace burner hearth by the other end of described housing.
Also can offer the air inlet port on described housing, the inner chamber of this housing is connected with outside air by this air inlet port.
Described housing can be made of first housing and second housing that separate; Described air inlet port is opened on described second housing, and the two ends of described second housing are threaded with described first housing, water-coal-slurry carrier pipe respectively.
After adopting such structure, water-coal-slurry is conveyed in the housing by carrier pipe, enters at last in the heat-conducting oil furnace burner hearth after the some turbulated tube turbulent flows atomizing in the housing inner chamber; Flow velocity was less when water-coal-slurry was passed through this nozzle, nozzle abrasion is reduced greatly, thereby make that nozzle is not fragile, service life is longer; When on housing, offering the air inlet port, also can in housing, introduce combustion air and enter in the heat-conducting oil furnace burner hearth with the atomized water coal slurry, helping burning, and after entering turbulated tube from the air that the external world introduces, can prevent that also water-coal-slurry from condensing in pipe.When described housing is made of first housing that separates and second housing, can be convenient to the installation and the maintenance of nozzle and internal part thereof.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model water-coal-slurry torch firing nozzle.
The specific embodiment
Referring to a kind of water-coal-slurry torch firing nozzle shown in Figure 1, this nozzle is used to atomize and enters the flow-like water-coal-slurry of heat-conducting oil furnace burner hearth burning, it comprises housing 1, places the some turbulated tubes 2 and the water-coal-slurry carrier pipe 3 of described housing 1 inner chamber, one end of described housing 1 links to each other with water-coal-slurry carrier pipe 3, and described turbulated tube 2 is connected with described heat-conducting oil furnace burner hearth by the other end of described housing 1.Described turbulated tube 2 is arranged in parallel.
As shown in Figure 1, also offer air inlet port 4 on described housing 1, the inner chamber of this housing 1 is connected with outside air by this air inlet port 4.When water-coal-slurry atomized, outside air was owing to the suction function of housing 1 inner chamber enters in turbulated tube 2 and the housing 1 like this.
For ease of installation, cleaning and the maintenance of turbulated tube 2, described housing 1 can be made of the first housing 1-1 and the second housing 1-2 that separate; Described air inlet port 4 is opened on the described second housing 1-2, and the two ends of the described second housing 1-2 are threaded with the described first housing 1-1, water-coal-slurry carrier pipe 3 respectively.
Torch firing nozzle of the present utility model can be installed on the heat-conducting oil furnace by the ring flange 1-1-1 that is provided with on the first housing 1-1.The described ring flange 1-1-1 and the first housing 1-1 are made into integration.
Outer end at the described second housing 1-2 also is provided with thread segment 1-2-1, is convenient to like this and being connected of other pipeline.
Described turbulated tube 2 can be fixedly connected in the inner chamber of described housing 1 by being arranged on the gripper shoe 5 in the housing 1.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement, these also should be considered as belonging to protection domain of the present utility model.
