Continue to consult Fig. 1, Fig. 4 and Fig. 5, this first heat exchanger 6 is located at the central part under the designated water level that steam produces container 2, by heat-exchange tube, formed, high-temperature flue gas enters through the import of the first heat exchanger, enters the second heat exchanger 7 successively after each heat-exchange tube being arranged in parallel by the outlet of the first heat exchanger.According to circumstances can also adopt multilayer circulation design, on heat-exchange tube, design the technological means such as radiating fin and improve its heat energy efficiency.High-temperature flue gas is in the flow process of the first heat exchanger 6, and the water producing in container with steam carries out heat exchange fully, makes thermal energy transfer in high-temperature flue gas to water, makes water fast boiling and produces steam, improves widely energy efficiency.This second heat exchanger 7 is for being located at fume pipe on extra feed tank inwall, and this fume pipe is located under the designated water level of extra feed tank 4.The flue gas being flowed out by the first heat exchanger outlet enters the second heat exchanger; In the second heat exchanger, flue gas flows around extra feed tank inwall, in its flow process with extra feed tank in water carry out heat exchange, waste heat in flue gas is fully passed in the water in extra feed tank, the water temperature of extra feed tank is raise, be convenient to the boiling that heats up.
Continuation is referring to Fig. 1, this extra feed tank produces container with steam and is communicated with by water pipe, on this water pipe, be provided with check valve 10, with guarantee for the water one direction of feed-tank flow to steam and produce container, when extra feed tank lack of water (as extra feed tank leaks), prevent aqueous reflux and affect the normal work that steam produce to hold.
Embodiment bis-
The structure division not being illustrated in the present embodiment is with embodiment mono-.
For the ease of operation, use, the utility model also includes controller, and this controller is assemblied in control cabinet 9, and this control cabinet can be arranged on directly or indirectly in supporting construction and (shown in Fig. 1～5, be directly installed on the outer wall of extra feed tank).Referring to Fig. 6, this controller is connected with master switch, magnetic valve, ignition electrode, feedback pin, water inlet switch, water level sensor, combustion gas inductor, blast inductor, fan switch and alarm by circuit respectively.This controller adopts existing control module.This magnetic valve is located on the pipeline of fuel gas supply system so that main valve in fuel gas supply system open after also by the supply of solenoid control combustion gas, with anti-gas-leak, cause disaster.This ignition electrode and feedback pin form the igniter of burner, to carry out automatic ignition operation; They are located on burner.This water inlet switch is the water inlet switch on extra feed tank, and it adopts solenoid electric valve, by opening with the water supply to extra feed tank; This water level sensor is located at extra feed tank inwall, for detection of the height of water level of extra feed tank.Combustion gas inductor is a kind of gas sensor, for detection of gas concentration, generally can be located near burner or around, to detect the gas concentration at burner place.This blast inductor is located at blower fan import department, in order to detect the blast size of blower fan import.Fan switch is for controlling the unlatching of blower fan or closing.This master switch and alarm (can adopt general audible-visual annunciator) are located at the convenient operation place in supporting construction, are respectively used to connect external power source and carry out alarm.Automatic Control Theory of the present utility model is as follows: after power-on master switch, (being generally 220V alternating current) switches on power, after the bypass supply circuit of via controller, generate various operating voltages (as the direct current of+10V) and normally work for controller and blower fan.Controller receives after starting-up signal by master switch, by controller, is controlled the unlatching of magnetic valve or is closed and the work of igniter; By water level sensor, detect the water level signal in extra feed tank simultaneously and pass to controller to control the opening and closing of water inlet switch; By blast inductor, detect the flue gas power of blower fan import department and pass to controller, by controller, control the unlatching of blower fan or close; By combustion gas inductor, detect near gas concentration burner and pass to controller with control work; Meanwhile, once there is in the course of the work abnormal conditions, by alarm, send warning again, cut off magnetic valve simultaneously.
This controller is also connected with air pressure inductor, and this air pressure inductor is located at steam and produces in container to detect steam pressure.Air pressure inductor detects steam and produces the vapour pressure in container and pass to controller, controlled the unlatching size of magnetic valve, thereby the combustion flame of control combustion device is strong and weak by controller.Too high when the pressure that air pressure inductor detects, as be greater than 1.5 atmospheric pressure, by controller, control magnetic valve, thus electromagnetic valve for adjusting flow, to reach safe and reliable object.During actual use, magnetic valve can be opened to size and be controlled at third gear, i.e. " little fire ", " moderate heat " and " big fire ", by air pressure inductor, detecting vapour pressure size respectively controls, during as 1 atmospheric pressure, control magnetic valve for " big fire " opening, during 1 to 1.5 atmospheric pressure, control magnetic valve for " moderate heat " opening, while being greater than 1.5 atmospheric pressure, control magnetic valve for " little fire " opening.
Specific works process of the present utility model is as follows: open master switch, switch on power, controller receives starting-up signal.By controller opens magnetic valve, to burner, carry out automatic feeding, with the ignition electrode in Time Controller control point fire device, carry out automatic ignition, by feedback pin by fired state signal feedback to controller.When the signal of feedback pin detection is " state catches fire ", the ignition electrode that controller is controlled stops igniting, again lights a fire, until light a fire successfully otherwise control ignition electrode by controller.If after loss of ignition repeatedly (being generally set as five times), by controller, control alarm and send alarm sound, remind user, also close solenoid valve shuts combustion source simultaneously.When controller receives off signal, control electronic valve simultaneously and close the combustion source that cuts off.In work simultaneously, by water level sensor, detect the water level situation of extra feed tank and pass to controller, when the low water level of water level in designated water level being detected, by controller, open water inlet switch extra feed tank is carried out to moisturizing, when being replenished to the high water level place of designated water level, stop moisturizing, with anti-overflow, cause disaster.In work simultaneously, by near gas concentration gas sensor detection burner, once the gas concentration detecting is too high, as in gas leakage or when burning, flame-outly can cause while waiting fortuitous event generation near gas concentration burner too high, controller will send warning by alarm (as audible-visual annunciator), control closed electromagnetic valve simultaneously, cut off combustion source.In work, also by blast inductor, detected the flue gas flow of blower fan import department, when flue gas flow is too small, as little fire burning, by controller by controlling fan switch and closing blower fan, to reach the object of economize on electricity.
