Description
Technical field
The utility model belongs to the combustion experiment furnace apparatus, particularly a kind of controllable adjustable drop tube furnace device.
Background technology
Drop tube furnace is the usual means that fuel such as a kind of coal dust, living beings carry out mechanism experiment, and fuel carries out the One-dimensional combustion reaction in stove.This device is simple relatively, and temperature is easy to control, has higher heating rate, and can realize continuous feed, can conveniently understand the burning and the emission performance of fuel.Conventional drop tube furnace mainly contains fuel inlet, air intlet and cigarette, ash outlet, and adjustable parameter is less.And the combustion apparatus such as boiler of reality have a plurality of fuel or air duct basically, and these passage different spatial change has significant effects to aflame aerodynamic field, concentration field etc., thereby burning and pollutant control are had very big influence.Therefore simple one dimension reaction is reacted true actual conditions than difficulty in the drop tube furnace.
In addition, combustion reaction all needs the regular hour, and fuel gets into burner hearth and generally passes through the stages such as preheating, diffusion, reaction, and drop tube furnace is less owing to size, and the fuel time of staying therein is generally shorter.Can be faster mix and reaction if fuel gets into burner hearth, help burning and after-flame in the burner hearth with combustion adjuvant etc.
Summary of the invention
The purpose of the utility model provides the drop tube furnace device of a kind of controllable adjustable fuel and combustion adjuvant variable quantity.
The technical scheme that the utility model adopts is:
The drop tube furnace body of heater is a cylindrical shell, and its end face is provided with the drop tube furnace import, and the bottom surface is provided with the drop tube furnace outlet; Two or more feeding-passages that can move up and down pass the end face of drop tube furnace body of heater, stretch in the drop tube furnace burner hearth, and act as a fuel respectively feeding-passage and combustion adjuvant feeding-passage use;
Feeding-passage is three layers of pipeline configuration, and innermost layer is a feeding-passage, links to each other with the external world through the feeding-passage inlet; Two outside layers is cooling-water duct, and the cooling-water duct in intermediate layer links to each other with the external world through the cooling water inlet, and outermost cooling-water duct links to each other with the external world through coolant outlet; It is fan-shaped feeding-passage shower nozzle that the bottom of feeding-passage is provided with the longitudinal section, and its surface is provided with a plurality of spray-holes.
The internal diameter of said spray-hole is 0.5～3 millimeter, and the injection direction of spray-hole and the angle between vertical direction are 0～85 °.
Be threaded engagement between said feeding-passage and the drop tube furnace body of heater.
The beneficial effect of the utility model is:
The described drop tube furnace of the utility model is compared with conventional drop tube furnace; Stove fuel amount and combustion-supporting dosage controllable adjustable have been realized; The sprinkler design of fuel channel and combustion adjuvant passage has been strengthened material and the interior main rapid mixing of firing fuel and air of drop tube furnace in the passage simultaneously, and this drop tube furnace can reflect the Actual combustion process more accurately.

The specific embodiment
The utility model provides a kind of controllable adjustable drop tube furnace device, below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
The structure of this drop tube furnace is as shown in Figure 1, and drop tube furnace body of heater 2 is a cylindrical shell, and its end face is provided with drop tube furnace import 3, and the bottom surface is provided with drop tube furnace outlet 4; Two or more feeding-passages that can move up and down pass the end face of drop tube furnace body of heater 2, stretch in the drop tube furnace burner hearth 1, and the feeding-passage 5 that acts as a fuel respectively uses with combustion adjuvant feeding-passage 6.Be threaded engagement between feeding-passage and the drop tube furnace body of heater 2.
The structure of feeding-passage is as shown in Figure 2, and feeding-passage is three layers of pipeline configuration, and innermost layer is a feeding-passage, links to each other with the external world through feeding-passage inlet 71; Two outside layers is cooling-water duct, and the cooling-water duct in intermediate layer is through cooling water inlet 73 as extraneous linking to each other, and outermost cooling-water duct links to each other with the external world through coolant outlet 72.The structure of feeding-passage shower nozzle is as shown in Figure 3, and it is fan-shaped feeding-passage shower nozzle 74 that the bottom of feeding-passage is provided with the longitudinal section, and its surface is provided with a plurality of spray-holes 75.The internal diameter of said spray-hole 75 is 0.5～3 millimeter, and the injection direction of spray-hole 75 and the angle between vertical direction are 0～85 °, changes because of the position is different.
Drop tube furnace body of heater 2 provides heat to keep the burning of fuel in burner hearth through auxiliary modes such as electrical heating.During work, solid fuel such as coal dust and combustion air etc. get into drop tube furnace burner hearths 1 through drop tube furnace import 3, and after the burning fully, the ash of generation and flue gas are through drop tube furnace outlet 4 discharges.Through fuel feed channel 5 and combustion adjuvant feeding-passage 6 move up and down and passage in the change of mass flow-rate, realized that position, the concentration of burning and product in the drop tube furnace is adjustable, made things convenient for understanding to combustion characteristics.
