The invention discloses an unpowered internal combustion jet ladle heating device. The unpowered internal combustion jet ladle heating device is characterized in that a heat exchange chamber is arranged on a steel ladle cover; exhaust holes are evenly distributed in the periphery of the steel ladle cover, and the exhaust holes are communicated with exhaust pipes in the heat exchange chamber; the exhaust pipes are communicated with an exhaust port; air inlet pipes are also arranged in the heat exchange chamber; the upper portion and the lower portion of each air inlet pipe are communicated with an air inlet and a combustion supporting air pipe respectively; a high-temperature-resistant gas pipe is arranged in the combustion supporting air pipe; the air inlet pipes are arranged in the exhaust pipes; an air flow measurement device and a gas flow measurement device are connected to a PLC; the PLC automatically adjusts the opening degree of an electric regulating valve according to feedback values of the air flow measurement device and the gas flow measurement device, so that the air-fuel ratio is controlled. According to the unpowered internal combustion jet ladle heating device, heat energy of waste gas is fully used for heating combustion supporting air by arranging a heat recovering system, and thus energy is saved; meanwhile, the air-fuel ratio is controlled through the PLC, and thus combustion is made more sufficient.
Description
Technical field
The present invention relates to a kind of smelting industry heater, be specifically related to a kind of unpowered I. C. jetting formula Ladle-casting apparatus.
Background technology
Ladle baking is a very important procedure in iron and steel is produced, and the technique of baking drastically influence the energy consumption of enterprise and the quality of product.Existing steel roasting process is all directly adopt combustor to toast one to one ladle, and bake process energy consumption is higher, and the coal that each ladle consumes in bake process is large-minded, and entreprise cost burden is heavier.Existing steel ladle baking device is when toasting ladle, all need reserve certain space for discharging waste gas at clad mouth, otherwise new thermal source cannot enter ladle, in the process of waste air, a large amount of heat risen is discharged with waste gas, and the heat utilization efficiency after gas-fired is lower.
Summary of the invention
For the deficiencies in the prior art, the present invention aims to provide a kind of unpowered I. C. jetting formula Ladle-casting apparatus, and it effectively can reduce the gas consumption amount of iron and steel enterprise when toasting ladle, significantly promotes the heat utilization efficiency of gas-fired simultaneously.
To achieve these goals, the present invention adopts following technical scheme:
A kind of unpowered I. C. jetting formula Ladle-casting apparatus, comprise steel ladle cover, it is characterized in that: steel ladle cover is provided with heat-exchanging chamber, the surrounding of steel ladle cover is evenly distributed with steam vent, steam vent is connected with the blast pipe in heat-exchanging chamber, blast pipe is connected with exhaust outlet, also air inlet pipe is provided with in heat-exchanging chamber, air inlet pipe is connected with combustion-aid air pipe with air inlet up and down respectively, high-temperature resistant gas pipe is provided with in combustion-supporting breather pipe, air inlet pipe is arranged in blast pipe, air inlet is also provided with air-flow measurement device, Gas Pipe is provided with electric control valve and gas flow measurement mechanism, air-flow measurement device and gas flow measurement mechanism are connected to PLC control device, PLC control device regulates the opening-closing size of electric control valve to control air-fuel ratio according to the value of feedback of air-flow measurement device and gas flow measurement mechanism automatically.
The tube wall of air inlet pipe can be preferably fold-type tube wall to increase heat exchange area.
High-temperature resistant gas pipe combustion-aid air pipe is deep in ladle, and the preferred 50-200mm of distance ladle bottom.
The summation of all steam vent cross-sectional areas is that combustion-aid air pipe enters the 6-10 of combustion air position cross-sectional area doubly.
Beneficial effect of the present invention is:
The present invention makes full use of heat energy from waste gas heat combustion air by arranging heat recovery system, improves efficiency of combustion, has saved the energy, controls air-fuel ratio by PLC control device simultaneously, and air-fuel ratio is remained unchanged when burning, and makes burning more abundant; The summation of all steam vent cross-sectional areas is that combustion-aid air pipe enters the 6-10 of combustion air position cross-sectional area doubly, ensure that the flow at high speed of the combustion air when Blower-free.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is air inlet pipe schematic cross-section of the present invention.
Detailed description of the invention
Below with reference to accompanying drawing, the invention will be further described, it should be noted that, the present embodiment, premised on the technical program, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to the present embodiment.
As Fig. 1, shown in 2, a kind of unpowered I. C. jetting formula Ladle-casting apparatus, comprise steel ladle cover 13, it is characterized in that: steel ladle cover 13 is provided with heat-exchanging chamber 4, the surrounding of steel ladle cover 13 is evenly distributed with steam vent 12, steam vent 12 is connected with the blast pipe 1 in heat-exchanging chamber 4, blast pipe 1 is connected with exhaust outlet 7, air inlet pipe 2 is also provided with in heat-exchanging chamber 4, air inlet pipe about 2 is connected with combustion-aid air pipe 11 with air inlet 3 respectively, high-temperature resistant gas pipe 15 is provided with in combustion-supporting breather pipe 11, air inlet pipe 2 is arranged in blast pipe 1, air inlet 3 is also provided with air-flow measurement device 5, Gas Pipe 8 is provided with electric control valve 9 and gas flow measurement mechanism 14, air-flow measurement device 5 and gas flow measurement mechanism 14 are connected to PLC control device, PLC control device regulates the opening-closing size of electric control valve 9 to control air-fuel ratio according to the value of feedback of air-flow measurement device 5 and gas flow measurement mechanism 14 automatically.
The tube wall of air inlet pipe 2 can be preferably fold-type tube wall to increase heat exchange area.
High-temperature resistant gas pipe 15 combustion-aid air pipe 11 is deep in ladle, and the preferred 50-200mm of distance ladle bottom.
