Abstract
The invention discloses a zero pressure high-temperature steam generator which comprises an inner container, an outer container, a burner, exhaust passages and a water supplement tank. The inner container is arranged inside the outer container, a water containing pool higher than the inner container is placed on the lower portion of the outer container, a steam cavity is placed on the upper portion of the outer container, and a steam output pipe communicated with the steam cavity is placed on the outer container. The water supplement tank is placed outside the outer container, the lower portion of the water supplement tank is communicated with the water containing pool through a water supplement pipe, and the upper portion of the water supplement tank is communicated with the steam cavity through a steam balance pipe. The steam output pipe is placed on a first exhaust passage, and a second exhaust passage communicated with the first exhaust passage passes through the interior of the water supplement tank. The burner enters into the exhaust passage from the bottom of the outer container and is communicated with an air blower through an air pipe. Tail gas produced by the burner enters the first exhaust passage and is discharged through the second exhaust passage. According to the zero pressure high-temperature steam generator, the temperature of the steam can be raised to more than 120 DEG C under a zero pressure condition, steam quantity is large, so that thermal efficiency is improved, and at the same time fuel is saved. The zero pressure high-temperature steam generator can be installed below a steam cabinet, and other space is not occupied.
Description
(1) technical field:
The present invention relates to steam providing apparatus, be specially a kind of without the pressure high-temperature steam generator.
(2) background technology:
Traditional steam generator is by fuel combustion, with the heat heating cold water that produces, the water temperature boiling that raises produces steam, safety without the pressure condition under, the boiling point of water and vapor (steam) temperature all do not have 100 ° of C of surpassing, and steam dish for the kitchen and require cannot satisfy customer requirements on velocity efficiency.Use can obtain high-temperature steam with the steam generator of pressure, but the safety of cooking apparatus and safeguard that conditional request is higher, cost is also high.
Application number be ZL201020159507.9's " automatic water supplement energy-conserving and environment-protective steam oven " utilize using waste heat from tail gas to carry out post bake to steam, safety without the pressure condition under, can obtain output vapor (steam) temperature and the automatic water supplement function of 102 ° of C, but in use also have following point:
1, cylindrical shape steam oven floor space space is large.
2, the fierce swing in the boiling water environment of the floating ball valve of rehydration in vapor chamber, easily cause abrasion deformation, produces in addition in addition the factor such as incrustation scale impact and cause movable device to lose efficacy, normally moisturizing.
3, vapor (steam) temperature can't satisfy customer requirements.
(3) summary of the invention:
For this reason, the present invention proposes a kind ofly without the pressure high-temperature steam generator, its objective is under the condition that there is no pressurization vapor (steam) temperature is increased, guarantee that the kitchen steams dish and can meet the demands on velocity efficiency.
Can realize above-mentioned purpose without the pressure high-temperature steam generator, comprise steam raising plant, difference is that described steam raising plant comprises inner bag, outer courage, burner, exhaust duct and water supply tank.Described inner bag is supported in outer courage by side exhaust outlet and lighting-up tuyere and base burning mouth, upper and lower parts in described outer courage are respectively the appearance pond that vapor chamber and the water surface exceed inner bag, the steam output pipe that is communicated with vapor chamber is set on outer courage, and described steam output pipe is placed in the first row air flue that is communicated with exhaust outlet; Described water supply tank is located at outside outer courage, and the water supply tank bottom is communicated with by filling pipe and holds the pond, and water supply tank top is communicated with vapor chamber by the balance of steam pipe, the inner second row air flue that is communicated with the first row air flue that arranges of water supply tank; Described burner is located in inner bag and by airduct by the port of inner bag and is communicated with air blast.
Operation principle of the present invention is that at first the tail gas (waste gas) that burner combustion is produced enter the first row air flue, utilize tail gas in the first row air flue (waste gas) heat to carry out post bake its temperature (high-temperature steam after heating outputs in use equipment) that raises to the steam in steam output pipe, then after tail gas (waste gas) entered the water heating of second row air flue to water supply tank, last tail gas (waste gas) was discharged to atmosphere from exhaust outlet.
For obtaining 120 ° of high-temperature steam institute Adopts measures more than C be
1, prevent that in other setting of the inlet port of steam output pipe the water droplet mixed vapour from entering the water fender in pipe.
2, arrange in described first row air flue the deflector of tail gas guide to rising heating steam efferent duct, tail gas (waste gas) refluxes under the effect of deflector, and the time of staying lengthens in the first row air flue, is conducive to the steam output pipe heat absorption.
The control device that described appearance pond is carried out normal moisturizing is floating ball valve of rehydration, and described floating ball valve of rehydration is located in water supply tank.
For preventing that floating ball valve of rehydration lost efficacy because the factors such as incrustation scale exerts an influence cause movable device, also be provided with the electromagnetism water compensating valve on described water supply tank, when the water level in steam raising plant lowers in the Security alert position, alarm activation electromagnetism water compensating valve connection is simultaneously opened, automatically carry out moisturizing, stop when reaching desired location.
Relevant reasonable size is in described outer courage: the water surface in described appearance pond exceeds inner bag 30mm～50mm, and the spacing that forms between described inner container side surface and bottom surface and outer courage is 30mm～50mm, and the height of described vapor chamber is 150mm～200mm.
Described outer courage is provided with steam pressure release valve, vapor (steam) temperature table and water level observation tube, and whether normal and outer courage internal pressure is too high to be beneficial to the interior water level of outer courage.
The invention has the advantages that:
1, the present invention arranges water fender in the steam output pipe import, deflector is set in exhaust duct without the pressure high-temperature steam generator, take full advantage of that in exhaust duct, the waste heat of tail gas heats steam output pipe, under the condition that there is no pressurization, vapor (steam) temperature is increased to 120 ° more than C, guarantee that kitchen steaming dish can meet the demands on velocity efficiency.
2, the inner bag of steam raising plant of the present invention is heated comprehensively, guarantees that under the small size condition disengagement area is large, and quantity of steam is large; The present invention adopts square structure can be arranged on the steamer bottom, does not take other space.
3, the present invention changes the former floating ball valve of rehydration of being located in vapor chamber and is located in water supply tank, has solved maintenance issues.
4, the present invention has reduced the water yield in the water supply tank, utilizes the balance of steam pipe to advance steam and tail gas heats institute's moisturizing, has guaranteed that the output vapor (steam) temperature is stable.
5, outer courage, inner bag and the steam output pipe when steam raising plant adopts aluminum alloy materials to make, and when burner uses the liquid alcohol-group fuel to carry out work, because the heat conduction efficiency of aluminum alloy materials is higher, under the double condition of High Efficiency Thermal conduction and recycling tail gas heat quantity, exhaust temperature is down to ° C discharging of 130 ° of C～140, has improved the utilization rate of heat that fuel produces.
