Description
Technical field
The utility model relates to steam raising plant field, relates in particular to a kind of Electrothermic steam generator.
Background technology
Steam generator (being commonly called as boiler) is mainly applicable to clothing factory, drycleaner's, restaurant, steamed bun shop, dining room, dining room, factories and miness, the places such as Bean Products Factory.Steam generator refers to the plant equipment of utilizing the heat energy of fuel or other energy water to be heated as to steam.The necessary <30L of volume, volume >=30L belongs to the category of boiler in " Safety Supervision on Special Equipment regulations ", the most of volume <30L of steam generator on market, so do not return technical supervision department supervision, have saved installation, cost of use.Steam generator, mainly according to fuel grade, can be divided into electric steam generator, fuel-steam generator, gas steam generator etc.
Because fuel-steam generator, gas steam generator exist the environmental protection such as environmental pollution and security problems, gradually replaced by electric steam generator in densely populated occasions such as cities, the trend of electric steam generator development mainly: (1) improves the electric steam generator thermal efficiency; (2) equipment manufacturing cost of the unit power of reduction electric steam generator; (3) operational flexibility and the automatization level of raising electric steam generator; (4) the more electric steam generator kinds of development are to adapt to different demands; (5) operational reliability of raising electric steam generator and auxiliary equipment thereof.
At present, there is following defect in electric steam generator: (1) steam produces slow, often needs more than ten minutes could produce steam; (2) water inlet is controlled and is adopted switch, because switch is operated under hot environment, the aging malfunctioning phenomenon of controlling easily occurs; (3) the incrustation scale cleaning producing is inconvenient, affects the service life of steam generator; (4) power is fixed, unadjustable.
Summary of the invention
Have above-mentioned defect for solving existing electric steam generator, the utility model provides a kind of simple in structure, steam to produce fast, self-timing cleaning incrustation scale, steam generator that power is adjustable.
For achieving the above object, the scheme that the utility model is taked is: a kind of steam generator, comprise main water box, and in main water box, be provided with electrothermal tube and water level probe, water level probe is located at electrothermal tube top, and main water box side is provided with water inlet and more than one steam (vapor) outlet; It is characterized in that: main water box downside is provided with the guide tank of an outwardly convex, electrothermal tube puts in this guide tank from corresponding main water box one side of guide tank.
As the improvement of such scheme, the isosceles trapezoidal structure that aforementioned guide tank is outer narrow inner width.The effect of guide tank is the contact area that increases water and electrothermal tube, and the steam that guiding produces upwards flows, and improves the generation of steam, improves the thermal efficiency; The supplementary flow direction of the guiding water yield, ensures not dry combustion method of electrothermal tube.The incrustation scale forming after the heating of guiding electrothermal tube, peels off the rear water tank bottom that automatically drops to, and is convenient to discharge outside casing.
As the Continual Improvement of such scheme, aforementioned water inlet is located at electrothermal tube below.The temperature of the cold water entering due to water inlet is lower than the temperature of the hot water in main water box, and its relative density is larger, and nature can move downward, like this can be fully to the abundant preheating of the cold water newly entering, and the higher hot water floating of temperature produces convection current, the generation of quickening steam.
Aforementioned water level probe is two water level probes that one is long and the other is short, and long is low-level probe, and short is high-level probe, and low-level probe extends to the position near electrothermal tube top, and high-level probe extends to the position near steam (vapor) outlet below.The effect of two water level probes is for control device provides water level signal,, just stops into water while being raised to high-level probe when waterborne; When waterborne while being raised to low-level probe, the electrothermal tube heating of just can switching on, water level just disconnects electrothermal tube during lower than low-level probe, stops heating, the dry combustion method of protection electrothermal tube.
The pressure relief safety valve that aforementioned main water box top is provided with vapor pressure while transfiniting.In the time that steam channel stops up, can drainage pressure, the explosion of prevention casing, ensures the safety of whole casing.
Aforementioned main water box outside is provided with the secondary water tank with intake tunnel and exhalant canal, and the exhalant canal of secondary water tank is connected with the water inlet of main water box, and intake tunnel is provided with magnetic valve.The effect of secondary water tank is buffered water flowing pressure, the flow direction of guiding current, and alleviate water fluctuation.
Aforementioned main water box bottom is provided with electronic blowoff valve.Can open by automatic or manual, the water in water tank is discharged outside casing together with adding thermogenetic incrustation scale, ensure the sanitation and hygiene of water body, extend the service life of electrothermal tube.
The intake tunnel of aforementioned auxiliary water tank is provided with pressure relief safety valve.
Aforementioned electric heat pipe is multistage power adjustable electric heat pipe, and its power is 15kW ~ 100kW.In conjunction with electronic-controlled installation, the following power of actual power that just can realize easily electrothermal tube is adjustable arbitrarily, in the time starting to start, can first open powerful one-level, and control inflow maintenance low wash water, reach the object of instantaneously producing steam, and then reduce step by step; And strengthen inflow, and in the time that the steam of needs is little, also can be reduced to minimum one-level, save electric energy.
Aforementioned steam generator also comprises the electronic-controlled installation of controlling its work, and this electronic-controlled installation is provided with the relay circuit that multistage power adjustable electric heat pipe is switched on or switched off, and controls the timing control circuit of electronic blowoff valve time opening.Electronic-controlled installation can also be controlled steam channel and close.
As from the foregoing, of the present utility model have a following advantage: simple in structure, reasonable in design, easily manufacture; Steam produces fast, can automatically arrange dirt; Secondary water tank coordinates with water level probe and replaces traditional switch, and supplementary water inlet is more stable, more scientific; Power is adjustable, can prevent dry combustion method, can prevent the excessive casing explosion of air pressure, can conveniently realize slitless connection with electronic automatic control device, can freely open or close multichannel steam channel.
