Abstract
The invention discloses a gas clashing type heating device and a heating method. The heating device comprises two opposite inlet gas passages and two back-to-back outlet gas passages, wherein the inlet gas passages and the outlet gas passages are made of heat insulation pipelines; the outlet gas passages are perpendicular to the inlet gas passages; the cross section areas of the outlet gas passages are larger than those of the inlet gas passages; the joints of the inlet gas passages and the outlet gas passages are gas clashing areas; heat transferring components, which are high in heat transferring performance, are arranged in the gas clashing areas. Compressed air is led into the heating device from the two opposite inlet gas passages, and clashes in the gas clashing areas, so that the temperature of the gas rises fast, and then the gas flows out from the two back-to-back outlet gas passages; the heat transferring components in the gas clashing areas transfer heat into a peripheral device connected with the heat transferring components, so as to heat media to-be-heated in the peripheral device. The gas clashing type heating device and the heating method have the advantages that the structure is simple; the manufacture cost is low; the heating speed is high; energy is saved; the efficiency is high; the use is clean and sanitary.
Description
Technical field
The present invention relates to a kind of gas collision type heater and heating means.
Background technology
High-temperature gas is widely used in the industry spot such as metallurgical steel-making industry.Conventional gas heating (as burning, electric heating etc.) is all the gas utilizing heat transfer, convection current, heat radiation first heat to be passed to heater near surface, more progressively makes gas temperature raise by heat convection.Make gas entirety reach required temperature, need certain heat transfer time.When heating with temperature difference mode of heating, for improving firing rate, just needing elevated external temperatures, strengthening thermograde, thus also increasing heat loss.
And the heating means of the opposed shock of internal channel high-speed gas are that a part of kinetic energy of high-speed compressed air and pressure energy are converted into energy (heat energy) in it, therefore can heat at short notice.And Compressed Gas is described as " the second largest energy of the mankind ", these heating means have the basis extensively utilized as seen.But there is not the relevant report of this respect at present.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, low cost of manufacture, thermal-stable and heat up gas collision type heater rapidly and the method that utilizes this device to heat.
For reaching above object, the present invention takes following technical scheme to be achieved:
A kind of gas collision type heater, it is characterized in that, comprise the two sections of subtend inlet airflow passages be made up of heat-insulating pipeline, two sections that are made up of heat-insulating pipeline outlet flow path dorsad, described outlet flow path is perpendicular to inlet airflow passages, and the sectional area of outlet flow path is greater than the sectional area of inlet airflow passages; Inlet airflow passages and outlet flow path junction are gas head-on collision district, and gas head-on collision district center is provided with the heat transfer component of good heat conductivity.
In such scheme, the cross section of described outlet flow path and inlet airflow passages is rectangle, and the sectional area of described outlet flow path is 4 ~ 8 times of the sectional area of inlet airflow passages.
A kind of heating means utilizing gas collision type heater, it is characterized in that, described heat transfer component is connected with a peripheral unit, by compressed air from two sections in opposite directions inlet airflow passages send into, air-flow collides in gas head-on collision district, by outlet flow path outflow dorsad after making gas temperature raise rapidly, now, heat transfer component in head-on collision district by gas-heated, and transmits heat in connected peripheral unit and heats required heat medium.
The present invention has the following advantages: firing rate is fast, thermal-stable, efficient energy-saving, sanitation and hygiene.In addition, heater structure is simple, durable, not fragile, can be used widely needing the industry spot of high-temperature gas.

Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of collision type gas-heating apparatus, comprise the inlet airflow passages 1 that two sections of subtends are arranged, 8 and two sections perpendicular to inlet airflow passages direction arrange outlet flow path 5, 6, gas channel 1, 8, 5, 6 are made up of pipeline 2, the cross section of outlet flow path and inlet airflow passages is rectangle, the sectional area of outlet flow path is 6 times of the sectional area of inlet airflow passages, all seals for pipe joints are good and inwall is provided with thermal insulation layer 7, inlet airflow passages and outlet flow path junction are head-on collision district 3, head-on collision district center has the good heat transfer component 4 of heat conductivility.Heat transfer component by flange 9 and bolt 10 be fixed on run through head-on collision district center before and after pipeline outer wall on.
Compressed air (300m/s) is sent in opposite directions from gas channel 1 and 8, in head-on collision, place of district 3 clashes into, because between two strands of air-flows, relative velocity is very large, after colliding, air velocity sharply declines, part kinetic energy is converted into rapidly interior energy (heat energy), gas temperature is raised rapidly, now, heat transfer component 4 in head-on collision district 3 by gas-heated, and transmits heat in connected peripheral unit.
As shown in Figure 3, heat transfer component 4 transmits heat in medium channel or container 11, heats the medium of required heating.Wherein heated medium can be gas or liquid, as air, combustion gas, water, steam water interface etc.
Numerical experiments is carried out to the device of the present embodiment, when inlet air flow is the air of 1atm, 600K, 300m/s, head-on collision district in inlet air flow direction center line on variations in temperature as shown in Figure 4, as seen from the figure, gas temperature can raise more than 45 degrees Celsius.
