Embodiment
Below in conjunction with the accompanying drawings and embodiment further illustrates the present invention.
As shown in figure 1, a kind of fire-suppressant gas Quick uniform heating device of the invention, including stainless steel tube 1 and it is located at two
The entrance 2 at end and outlet 3, gas enters stainless steel tube 1 by entrance 2, with the internal thread 9 of stainless steel tube 1 with the side of threaded connection
First regulation pipe 4 of formula connection, the second regulation pipe 5, to the position of fixed fast gas heating module 7, the outer wall of stainless steel tube 1
METAL HEATING PROCESS silk 6 is wound, stainless steel tube 1 is heated up by way of heat conduction, and the fast gas heating in the pipe of stainless steel tube 1
Module 7, to increase heat exchange surface area, strengthens heat transfer effect, and the sensor detection mouth 8 that stainless steel tube 1 exports the welding of 3 ends can be with
It is connected with a thermocouple, the screw thread 9 at outlet 3, for fixing the second regulation pipe 5, the insertion groove 10 of arrival end, perpendicular to insertion
The self-locking grooves 11 of groove, the first regulation pipe 4 for locking different length.
First regulation pipe 4 has three types, is divided into I, II, III type.The length L of regulation pipe is L=45+ (model) X20 (examples
If such as II type is 45+20X2=85), unit is millimeter.The right-hand member of every kind of regulation pipe all welds long 1 millimeter, wide 2 millimeters, high 2 milli
The metallic bond of rice, is entered during installation by the insertion groove 10 at the entrance 2 of stainless steel tube 1, by the first regulation pipe 4 after fully entering
Turn clockwise 60 ° and enter self-locking grooves, so that the position of the first regulation pipe 4 is locked, while also having determined that fast gas adds
The position of thermal modules 7.Because the length of the unit of fast gas heating module 7 is all 20 millimeters, installs different types of first and adjust
Section pipe 4 can just control the quantity of the unit of fast gas heating module 7 inside stainless steel tube 1 to adjust exerting for heat convection
Sai Er numbers, control Outlet Gas Temperature.Simulate and calculate by software, gas temperature to be heated is at 30 DEG C -70 DEG C, the heat time
50 milliseconds -100 milliseconds are needed, the heating of fast gas heating module 7 distance is greater than 80 millimeters and preferably uses III type regulation pipe, 70
At DEG C -120 DEG C, the heat time needs 100 milliseconds -120 milliseconds, and the heating of fast gas heating module 7 distance is greater than 100 millis
Rice, preferably using II type regulation pipe, at 120 DEG C -200 DEG C, the heat time needs 120 milliseconds -140 milliseconds, fast gas heated mould
The heating of block 7 distance is greater than 130 millimeters and preferably uses I type regulation pipe.
METAL HEATING PROCESS silk 6 is wound around on the wall of stainless steel tube 1, and two circle METAL HEATING PROCESS silks the distance between 6 are 5 millimeters,
Because the heat transfer type of METAL HEATING PROCESS 6 pairs of stainless steel tubes 1 of silk is heat conduction, so being close to the spot temperature of tube wall most in heater strip
Height, and the portion temperature in the middle of two METAL HEATING PROCESS silks is minimum.Calculated by simulating, when setting heating-up temperature is below 200 DEG C
When, the temperature difference maximum on metal tube is i.e. 1% no more than 1.2 DEG C.METAL HEATING PROCESS silk 6 transfers heat to pipe by way of heat conduction
Wall and fast gas heating module, then transfer heat to gas in the form of convection current, heat conduction.METAL HEATING PROCESS silk 6 is by temperature
Spend the size of current that controller control passes through heater strip：Thermocouple detects gas temperature less than setting at sensor detection mouth 8
When constant temperature is spent, temperature controller can increase heater strip internal current, increase heater strip caloric value, otherwise will reduce electric current, drop
Lower calorific value.
The effect of fast gas heating module 7 is enhancing heat transfer effect, increases the nusselt number of heat exchange, within a short period of time
Obtain the gas of uniform temperature.Each unit of fast gas heating module is made up of copper-silver mixing material.Preparation method is
On the surface of foam copper by electroplating the silver of attached last layer micron level thickness.The technical requirements of foam copper are PPI 130 ±
10, surface density is 2000g/m3, through-hole rate more than 98%, 0.1 millimeter -0.3 millimeter of aperture.It is fabricated to 8 millimeters of diameter, length 20
The unit of a fast gas heating module is used as after the cylinder of millimeter, electroplate.The beneficial effect bag of electroplating surface silver
Include：Prevent that copper from aoxidizing in atmosphere, cause influence heat-transfer effect and porosity；Strengthen heat convection effect.Foam metal
The characteristics of be that specific surface area is very big.So when gas is by fast gas heating module, can be in fast gas heating module
Sufficiently heated and mixed in space, to reach uniform and stable temperature.The effect of fast gas heating module is substantially
The surface area of heat convection is increased, that is, increases nusselt number.
After opening temperature controller and METAL HEATING PROCESS silk 6, equipment is heated to after design temperature, hot gas to be added is from entering
Mouthfuls 2 enter device, and fast gas heating module 7 is reached by the first regulation pipe 4, and in fast gas heating module 7 sections obtain
Fully heating and mixing, then reaches at sensor detection mouth 8 by regulation pipe 5, mouth 8 is detected to temperature controller from sensor
Feedback temperature data, if gas temperature is higher or lower than the temperature of setting, temperature controller will be reduced or improved accordingly
The power of METAL HEATING PROCESS silk so that gas temperature is maintained on design temperature.
The measure that imperial 1301 gas is breathed out in three groups of experiments has been carried out in experiment, 10m/s situation has been reached in outlet gas velocity
Under, 30 DEG C, 50 DEG C and 70 DEG C of gas temperature is set respectively, and Outlet Gas Temperature is respectively with design temperature maximum disparity
0.7 DEG C, 0.8 DEG C and 0.7 DEG C, and the gas temperature maximum difference of exit diverse location is less than 0.01 DEG C.
The gas Quick uniform heating device is easy to use, simple in construction, and cleanliness without any pollution, can be in the very short time
Inside obtain the uniform hot gas of temperature.Small volume, can be widely used in and obtain needing the occasion of uniform temperature gas.Together
When, the present apparatus is using fast gas heating module to solve existing heat transfer problem, reduces heat-exchange time, makes gas temperature
Degree is more uniform, greatly improves heat exchange efficiency.
