Specific embodiment
Referring to figs. 1 to 4, the gas-burning type steam generator using closing cartridge heater 1 of the present invention includes the present invention The closing cartridge heater 1 is arranged on the gas burner 2 of 1 lower section of closing cartridge heater, is connected to the closing cartridge heater The exhaust fan 3 of 1 upper end, the automatic water inflow device 4 being connected on closing 1 lateral wall of cartridge heater;The closing cartridge heater 1 Inner upper is provided with partition plate 11, and the inside of the closing cartridge heater 1 is separated to form heating chamber 12 and gas collection by the partition plate 11 Chamber 13, the air collecting chamber 13 are located at the top of the heating chamber 12, exhaust outlet are offered in the upper end cavity wall of the air collecting chamber 13 19, the air inlet of the exhaust fan 3 connects the exhaust outlet 19;The upper end of the closing cartridge heater 1 is provided with steam output pipe 14, the steam output pipe 14 connects the heating chamber 12 through the air collecting chamber 13 and lower end;Under the closing cartridge heater 1 End is provided with upward concave combustion chamber 15, and the lower end of the heating chamber 12 is formed with the annular-heating around the combustion chamber 15 Water channel 16, the gas burner 2 are set at the lower port of the combustion chamber 15;The heating chamber 12 is internally provided with more Tortuous heating tube 17, the both ends of the heating tube 17 are respectively communicated with the combustion chamber 15 and air collecting chamber 13;The automatic feeding water Device 4 includes water tank 41, the ball-cock assembly 42 being arranged on inside the water tank 41, the sidewall upper of the water tank 41 be provided with into The mouth of a river 411, the ball-cock assembly 42 control the opening and closing of the water inlet 411, inlet opening are offered in the cavity wall of the heating chamber 12 110 and gas port 111, the gas port 111 top of the heating chamber 12 is set, the inlet opening 110 is located at the air guide The lower section in hole 111, the lower end of water tank 41 are connected by water inlet pipe 43 in the inlet opening 110, and the upper end of water tank 41 passes through air guide Pipe 44 connects gas port 111.Operation principle using the steam generator of closing cartridge heater 1 of the present invention is as follows:First The water inlet 411 of water tank 41 is connected into outer water tube, the clear water in outer water tube is entered through water inlet 411 in water tank 41, and It is flowed into through water inlet pipe 43 and inlet opening 110 inside heating chamber 12, since 41 upper end of water tank passes through gas-guide tube 44 and gas port 111 It is connected with heating chamber 12, will form linker between heating chamber 12 and water tank 41, the water surface inside the two will remain in same height On degree, persistently add water until when the water surface in water tank 41 reaches setting height, ball-cock assembly 42 controls water inlet 411 to close;Then, Gas burner 2 is lighted a fire, exhaust fan 3 starts, and combustion gas carries out the closing cartridge heater 1 of top in 15 internal-combustion of combustion chamber Heating, the heat that when burning radiates around are absorbed by the annular-heating water channel 16 around combustion chamber 15;Simultaneously because it takes out The effect of wind turbine 3 to generate negative pressure in air collecting chamber 13, and under suction function, the fresh air of 15 lower section of combustion chamber is fired from trend It burns in room 15 and moves so that the burning of the combustion gas in combustion chamber 15 is more abundant;Also, the high-temp waste gas generated after burning also will It is drawn under suction function in heating tube 17, the bending of heating tube 17 sets the contact surface that can be improved with clear water in heating chamber 12 Product heats clear water so as to which the heat of extreme portions is discharged into clear water, realizes the utilization to heat in high-temp waste gas;So Afterwards, the exhaust gas after burning is entered from heating tube 17 in air collecting chamber 13 and exhaust fan 3, is finally discharged to steam hair by exhaust fan 3 Outside raw device;Clear water in heating chamber 12 becomes steam after being heated, and the steam output pipe 14 from 1 upper end of closing cartridge heater is defeated Go out to being utilized outside steam generator;During clear water in heating chamber 12 is constantly converted into steam output, heating The water surface in chamber 12 and water tank 41 slowly declines, and ball-cock assembly 42 controls water inlet 411 to open at this time, the automatic past water of outer water tube Add water in case 41 and heating chamber 12, so as to fulfill the function that steam generator realizes automatic water supplement is made.
In the present embodiment, enter resistance in heating tube 17 to reduce high-temp waste gas, increase by 17 lower end of heating tube and inhale The area of gas port, specifically, the lower end of the heating tube 17 are arranged to inclined inclined-plane and extend into the combustion chamber 15.And And specifically, part of the heating tube 17 in the heating chamber 12 is moved towards in continuous S-shaped, to further improve with adding The contact area of clear water in hot chamber 12.Meanwhile in order to be evenly heated to the clear water in each area in heating chamber 12, Specifically, all heating tubes 17 are equidistantly in line in the horizontal direction in the heating chamber 12.In the present embodiment In, it is preferable that the heating tube 17 shares 8.
After steam generator operation completion, the clear water inside the heating chamber 12 is discharged for convenience, in this implementation In example, specifically, the drainpipe 18 that upper end connects the heating chamber 12 is provided in the combustion chamber 15, on the drainpipe 18 It is connected with switch valve;So clear water in heating chamber 12 can be discharged by opening the switch valve.
The above is the better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as its with Any same or similar means reach the technique effect of the present invention, should all fall under the scope of the present invention.
