Technical field
The utility model relates to a kind of steam raising plant, particularly a kind of small-sized gas steam generator that is applicable to catering industry.
Background technology
Catering industry belongs to the high energy consumption industry, and need consume the operating process such as boiling that a large amount of heat energy are used for food and dish every day.And in general restaurant, street restaurant, boiling all is to be undertaken by the water generates steam in the direct heating kettle of stove.Because the moisture storage capacity of pot is big, heat exchange area is little, and the material thermal conductivity of pot is low, causes temperature rise slow, and the thermal efficiency is low, and energy waste is serious.When intermittently using, be to accelerate yield rate particularly, must do not stop working and keep pot interior water and open, during this period of time, waste fuel in vain especially.
The waste of fuel has not only increased the producer's cost, and has caused the waste and the problem of environmental pollution of non-renewable energy resources.The content of utility model
Along with energy problem and problem of environmental pollution become the focus that the whole world is paid close attention to, people press for a kind of digesting apparatus of low energy consumption high-efficiency rate.
At the problems referred to above of present catering industry existence and people's needs, the purpose of this utility model is to provide a kind of small-sized combustion and steam generating means, this steam raising plant heat exchange area is big, the heat transfer coefficient height, it is fast to steam, it is stable to go out vapour, and safe and reliable, is particularly suitable for the catering industry boiling and uses.
In order to achieve the above object, the utility model provides a kind of small gas steam generator, and it comprises steam raising plant, outlet port, water inlet pipe and the running water valve on shell, gas inlet pipe, igniter, burner, burner top.Its steam raising plant is a copper pipe formula heat exchanger, is connected with water separator at heat exchanger outlet, and decompression pressure-stabilizing constant flow device is installed on water inlet pipe; At steam (vapor) outlet a carriage is arranged.
At the also middle wastewater discharge pipe in addition of above-mentioned water separator, pipe one end inserts the bottom of water separator.
Have fin on the copper pipe of above-mentioned copper pipe formula heat exchanger, to increase its heat exchange area.
Above-mentioned igniter is installed on the gas inlet pipe road, by an electromagnetism gas control valve that connects with starting switch, and piezoelectric ceramics high voltage arc switch, kindling material pipe constitute.The starting switch push rod contacts with the spool of electromagnetism gas control valve, a temperature difference heat galvanic couple that is positioned at burner is connected on the solenoid of electromagnetism gas control valve, be connected with a slow fire kind pipe in the exit of magnetic valve, the outlet side of kindling material pipe is stretched in the burner, also be connected to an ignitor switch on starting switch, the igniting needle of ignitor switch stretches in the burner and forms electricity sparking point with the kindling material pipe port of export.
A water control through transport gas valve also is housed between the fuel gas inlet pipe of magnetic valve igniter gas outlet pipe and burner, reaching the spool that is connected with spring by a spring in the valve body forms, the opposite side of spool is connected with a push rod, and the elastic diaphragm of the decompression pressure-stabilizing constant flow device on the other end of push rod has a push pedal and is installed in water inlet pipe contacts.
Its operation principle is: depress starting switch, then the electromagnetism gas control valve is backed down, and combustion gas enters the kindling material pipe through the electromagnetism gas control valve, simultaneously rotating switch, connect ignitor switch, the electrode of piezoelectric ceramics produces high-voltage spark and lights the combustion gas that exports out from the kindling material pipe.Kindling material heating temperature difference heat galvanic couple makes it produce electric current, and the electromagnet of electromagnetism gas control valve makes the electromagnetism gas control valve keep opening the valve state just with the spool adhesive self-locking of electromagnetism gas control valve.Open inlet valve, hydraulic pressure is opened decompression pressure-stabilizing constant flow device and is kept water pressure invariableness in the gas steam generator, its spool is subjected to displacement simultaneously, driving the valve inner septum moves, make the spool that backs down the water controlled linkage gas valve with the valve rod of the contacted water controlled linkage gas valve of barrier film simultaneously, the water controlled linkage gas valve is opened, and combustion gas enters burner, by the kindling material ignition combustion.Heating copper tube with fins formula heat exchanger makes water boiling in the pipe, and hot water undergoes phase transition after entering steam-water separator, carries out carbonated drink separation.The article of water vapour on steam outlet pipe output heating carriage, the static pressure of the water in the steam-water separator is relevant with decompression pressure-stabilizing constant flow device.
As mentioned above, as can be seen, the small gas steam generator that the utility model provides has following advantage:
(1), save the energy and produce steam fast because heat exchanger is the copper pipe heat exchanger that has fin, so heat exchange area is big and heat transfer coefficient is high, the thermal efficiency of steam generator is higher.
(2), make that flow of inlet water is constant, the pipe internal pressure is stable, so produce steam stable because decompression pressure-stabilizing constant flow device is arranged on the water inlet pipe.
(3) the water controlled linkage gas valve is opened and has been guaranteed to cut off combustion gas when hydraulic pressure is little or anhydrous, prevents dry combustion method.
(4) use of temperature difference heat galvanic couple makes that when burner is flame-out the interior electric current of galvanic couple reduces or disappears, and the magnetic valve of electromagnetism gas control valve can cut out automatically, has guaranteed air tight.
Description of drawings
Below in conjunction with accompanying drawing small gas steam generator of the present utility model is described further:
Fig. 1 is a small gas steam generator orthogonal view;
