Description

TECHNICAL FIELD

[0001] The utility model relates to high pressure airflow preparation technical field, concretely relates to a kind of equipment for generating high-speed high-temperature airflow using laser irradiation heat conduction. BACKGROUND

[0002] High-speed high-temperature airflow is widely used in metallurgy, manufacturing, processing and other industries, effectively ensuring the normal execution of the above process. For example, in the ironmaking process, high-speed high-temperature airflow can be used for blast furnace preheating and blast; in the steelmaking process, high-speed high-temperature airflow can be used for oxygen supply for converter and electric furnace; in the material detection field, high-speed high-temperature jet can be formed to simulate some special environment for detecting sample materials.

[0003] However, the equipment for preparing high-speed high-temperature airflow in current industrial production mainly includes the following:

[0004] 1. Regenerative equipment: uses regenerative materials to heat air, but the maximum temperature is limited by the materials, the test time is limited by the volume of the regenerator, and the construction, maintenance and use cost is relatively high, which is not economical, and the test interval is relatively long due to the long preparation time of the regenerator.

[0005] 2. Combustion and electric auxiliary heating equipment: combustion usually uses hot blast furnace, burns fuel in the combustion chamber, and forms hot blast after high purification treatment to meet the needs of specific fields; electric auxiliary heating uses airflow compressor and electric heating device to compress airflow to high pressure state, and reheats the pressurized airflow through the heating device to produce high-temperature high-pressure airflow that meets the temperature and pressure conditions, and then releases the airflow in a directional manner to produce high-speed high-temperature airflow. The energy waste of these two kinds of equipment is relatively large, and due to the limitations of mechanical pressure bearing capacity, temperature bearing capacity and mechanical weight or size requirements, the airflow speed is not very high, and the utilization value is relatively low.

[0006] 3. Shock wave / piston compression equipment: uses shock wave or piston to adiabatically compress airflow, which can achieve high temperature, but the available time is relatively short, requires certain test equipment, and it is difficult to carry out propulsion test, and the charging preparation time is relatively long for large equipment.

[0010] The pressure gas tank includes a pressure gas tank body, an airflow inlet end and an airflow outlet end. The pressure gas tank body has a tapered airflow inlet end and a tapered airflow outlet end at both ends along the axial direction. A impeller is coaxially installed inside the pressure gas tank body.

[0011] At least one laser entrance window is formed on the pressure gas tank body along the circumferential direction. The laser is transmitted to the corresponding laser head through an optical fiber. One laser head is installed at each laser entrance window. The laser emitted by the laser head irradiates the impeller through the laser entrance window.

[0012] Further, the impeller includes a ring-shaped tungsten-rhenium alloy plate and a copper plate. The ring-shaped tungsten-rhenium alloy plate is coaxially installed inside the pressure gas tank body. Multiple copper plates are installed side by side inside the ring-shaped tungsten-rhenium alloy plate along the axial direction. Multiple through holes are formed on the surface of the copper plate for airflow to pass through. The laser generated by the laser passes through the laser entrance window on the pressure gas tank body and irradiates the ring-shaped tungsten-rhenium alloy plate. The ring-shaped tungsten-rhenium alloy plate generates heat, which is conducted to the inside of the pressure gas tank body through the copper plate inside the ring-shaped tungsten-rhenium alloy plate.

[0013] In order to quickly and uniformly conduct the heat energy generated by laser irradiation to the impeller to the inside or around of the pressure gas tank body to ensure the rapid and uniform heating of the incoming airflow, the structure of the impeller is optimized and designed. The ring-shaped tungsten-rhenium alloy plate and the copper plate are used in cooperation. The ring-shaped tungsten-rhenium alloy plate is a ring-shaped plate structure made of tungsten-rhenium alloy material. Tungsten-rhenium alloy has high melting point, high thermal conductivity, high strength and plasticity, fewer cracks and holes, good radiation resistance and fracture resistance. The ring-shaped tungsten-rhenium alloy plate is coaxially installed inside the pressure gas tank body.

The heat is quickly conducted and dispersed to the inside of the pressure gas tank body through the copper plate welded inside the ring-shaped tungsten-rhenium alloy plate. The airflow passing through the pressure gas tank is continuously and uniformly heated. At the same time, the pressure in the tank body also increases with the increase of the temperature in the tank body. On the other hand, the copper plate quickly conducts the heat generated instantly on the ring-shaped tungsten-rhenium alloy plate, reduces the influence of local overheating and thermal stress, and protects the ring-shaped tungsten-rhenium alloy plate.

During operation, the linear drive module drives the adapter plate and the laser head to reciprocate in the front-back direction. The linear drive module can be selected from the structural components with linear sliding drive function in the prior art, including but not limited to a screw rod motor drive assembly.

[0017] In order to make the temperature in the pressure tank body more uniform and avoid damage caused by long-time irradiation of the laser on the same position of the impeller, the following specific structure design is made: first, the rotating shaft, the copper plate and the annular tungsten-rhenium alloy plate are driven by the rotary drive assembly to rotate at a constant speed around the center axis of the pressure tank body, and at the same time, the linear drive module drives the laser head to reciprocate along the length direction of the laser incidence window, so that the laser uniformly irradiates different positions of the annular tungsten-rhenium alloy plate, and the annular tungsten-rhenium alloy plate is heated more uniformly.

[0018] Further, two airflow inlet ends are provided, one end of the pressure tank body and the airflow inlet end are cooperatively mounted, the mounting flange is provided with two symmetrically arranged openings, the two airflow inlet ends are respectively arranged in the two openings, and an installation gap is formed between the two airflow inlet ends, and the rotary drive assembly is installed in the installation gap.

[0019] By improving the structure of the airflow inlet end, two symmetrically arranged conical airflow inlet ends are formed at one end of the pressure tank body, which on the one hand ensures the uniformity of the airflow entering, and on the other hand forms an installation gap between the two airflow inlet ends for installing the rotary drive assembly.

[0020] Further, the copper plate is uniformly provided with a plurality of reinforcing plates radially and outwardly protruding, and the reinforcing plates are respectively welded to the outer side of the rotating shaft and the inner side of the annular tungsten-rhenium alloy plate at the lengthwise two ends.

[0021] By arranging the reinforcing plates, on the one hand, the structure of the copper plate can be reinforced to better cope with the fluid of the air flow, and on the other hand, the end of the reinforcing plate can be used as a welding site to increase the welding area of the copper plate with the rotating shaft and the inner side of the annular tungsten-rhenium alloy plate, and the structure of the copper plate is more stable.

[0022] Further, two laser incidence windows are oppositely arranged on the pressure gas tank body along the circumferential direction.

[0023] In specific applications, the number of lasers arranged and the number of laser incidence windows arranged on the pressure gas tank body can be selected according to actual conditions.
