Abstract
The utility model relates to a gas natural circulating type domestic steam generator, which is composed of a steam generator, a water tank and a water-falling pipe and a water-steam rising pipe communicated with the steam generator and the water tank. The utility model is characterized in that the steam generator is composed of a burner, a combustion chamber, a heat exchanger, upper part and lower part water distributors and a water-steam collector; a cylindrical heat-insulation cylinder is arranged in the water tank and is communicated with the water-steam rising pipe, and thus, the water steam in the water tank is separated twice into anhydrous saturated steam for people to use. Meanwhile, the utility model has the advantages of high heat efficiency, less operation noise, little damage, safety and convenient operation.
Description
The utility model relates to a kind of steam generator, exactly is a kind of gas type natural recirculating type household steam generator.
Nearly water at atmospheric pressure steam has a wide range of applications in the family, produces health hot water for people's shower as available absorption process; Available condensation method heats up room air; Also available its steams various food etc.Steam generator is of a great variety at present, is used to steam food though can produce a large amount of steam, mostly needs to use than under the stable status at hydraulic pressure, and all can not produce anhydrous saturated vapor.
The water-vapo(u)r density that the purpose of this utility model provides before and after a kind of fin heat exchange pipe that relies in the heat exchanger is poor, promote water by the fin heat exchange pipe Natural Circulation, the gas-vapor mix in fin heat exchange pipe exit is separated in water tank, thereby export the gas type natural recirculating type household steam generator of first water saturation steam.
The purpose of this utility model is realized by following technical scheme.
The utility model is made up of the downcomer and the steam tedge of steam generator, water tank, water inlet pipe, connection steam generator and water tank, it is characterized in that:
A, steam generator comprise the combustion chamber of its outer coiling endothermic tube, place the burner under it, heat exchanger placed on it, be loaded on the heat exchanger right side and be embedded in the upper water distributor that the heat exchanger tube in the fin is communicated with, be loaded on the bottom water dispenser that the lower right side, combustion chamber is communicated with endothermic tube, upper water distributor and be loaded on steam gatherer on the left of the heat exchanger with cover;
Be provided with a cylindrical heat insulation tube in b, the water tank, the steam tedge is communicated with it, and the bottom has a filling pipe to be communicated with water tank, and water tank is provided with steam (vapor) outlet, and safety valve also is equipped with level control switch for water on it.
During use, the level control switch for water that closes, if the interior water level of water tank is lower than the lower limit of setting, then gas electromagnetic valve is closed, and the water tank water intake magnetic valve is opened, and after water tank added water to the water level lower limit of setting, gas electromagnetic valve was opened, and burner is lighted; Prescribe a time limit to the water level of setting when continuing to add water, entering water electromagnetic valve is closed, and at this moment water tank adds the water end.Endothermic tube outside the coiling combustion chamber and heat exchanger tube are by twice supplementing water of bottom water dispenser and upper water distributor, heat absorption heats up and part boiling vaporization back forms gas-vapor mix and enters in the steam gatherer and to enter through the steam tedge that heat insulation tube carries out steam separation first time in the water tank, most of high-temperature water falls in the heat insulation tube, and carry outside the steam effusion tube of a small amount of high-temperature water, enter the above space of water level limit in the water tank, after carrying out the steam separation second time, anhydrous saturated vapor is discharged for people to use from steam (vapor) outlet, the high-temperature water that falls in the heat insulation tube converges the interior water of water tank, flow into the bottom water dispenser through downcomer, the thrust that is produced by heat exchanger tube both sides density contrast again, flow into heat absorption intensification vaporization in endothermic tube and the heat exchanger tube once more, so carry out self-loopa.Not the time spent, discharging valve is opened in outage, with surplus water emptying in the system.
The utility model has the advantages that the gas-vapor mix of discharging in the reason heat exchanger tube carried out twice separation in water tank, so output is that anhydrous saturated vapor is for people to use, thermal efficiency height, the operation noise is little, not fragile, safe and reliable, easy to use.
Fig. 1 is the utility model structural representation.
Fig. 2 is the water tank cutaway view.
By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.
Embodiment:
(referring to Fig. 1,2) outside it, put burner 8 below the combustion chamber 7 of coiling endothermic tube 6, heat exchanger 9 is put in the top, being loaded on heat exchanger 9 right sides has one to be embedded in the upper water distributor 10 that the heat exchanger tube in the fin 18 is communicated with cover, is loaded on 7 lower right sides, combustion chamber and forms steam generator 1 by a bottom water dispenser 11 that is communicated with endothermic tube 6, upper water distributor 10 and the steam gatherer 12 that is loaded on heat exchanger 9 left sides.Adorn a cylindrical heat insulation tube 13 in the water tank 2, steam tedge 5 is communicated with it, and the bottom has a filling pipe 14 to be communicated with water tank 2, has steam (vapor) outlet 15 on the water tank 2, safety valve 16 is housed, level control switch for water 17.Water tank 2 is positioned at steam generator 1 top and by downcomer 4 and steam tedge 5 both is communicated with.Entering water electromagnetic valve 19 is housed on the water inlet pipe 3, discharging valve 20 is housed on the adjutage, gas electromagnetic valve 21 is housed on the air inlet pipe.
