According to the steam generation system provided by the application, continuous output of steam can be realized through alternate steam exhaust and steam storage of the plurality of steam generation units; the steam generation unit is in a relatively closed environment, so that the formed steam can be accumulated to form a larger pressure, and the output steam has a higher pressure; in addition, the heating power of the steam generating unit does not need to be increased when the continuous high-pressure steam is formed, so that the increase of energy consumption and adverse effects on manufacturing cost, service life and the like of each part of a product caused by high-power heating are avoided.
Referring to fig. 1 and 2, the present embodiment is described by taking an example that the steam generator includes two steam generating units. In the present embodiment, the steam generating system includes a first steam generating unit 1 and a second steam generating unit 2, the first steam generating unit 1 and the second steam generating unit 2 being identical. That is, the first steam generation unit 1 and the second steam generation unit 2 have the same structure and operation performance.
Referring to fig. 3 to 5, in one embodiment, the first steam generating unit 1 includes a base, and a first fluid channel 11 and a first heating body 12 cast in the base. The first fluid channel 11 may be wound in a flat spiral shape, and the first heating body 12 is a plurality of U-shaped heating pipes, which are sleeved in a flat spiral-shaped inner space formed by the first fluid channel 11. The heating pipe and the fluid channel are arranged in this way, so that the heating pipe and the fluid channel have the effects of high heat efficiency and high steam generation speed. The liquid may be heated to steam during the flow in said first fluid channel 11. The first fluid channel 11 has a first liquid inlet 111 and a first vapor outlet 112, the first liquid inlet 111 being connected to the liquid inlet main channel 61 by an on-off controllable valve, and the first vapor outlet 112 being connected to the vapor outlet main channel 5 by an on-off controllable valve.
With continued reference to fig. 3 to 5, the second steam generating unit 2 has the same structure as the first steam generating unit 1. That is, in an embodiment, the second steam generating unit 2 includes a base body and a second fluid passage 21 and a second heating body 22 cast in the base body. The second fluid channel 21 may be wound in a flat spiral shape, and the second heating body 22 is a plurality of U-shaped heating pipes, which are sleeved in the flat spiral inner space formed by the second fluid channel 21. The heating pipe and the fluid channel are arranged in this way, so that the heating pipe and the fluid channel have the effects of high heat efficiency and high steam generation speed. The liquid may be heated to steam during the flow in said second fluid channel 21. The second fluid channel 21 has a second liquid inlet 211 and a second vapor outlet 212, the second liquid inlet 211 being connected to the liquid inlet main channel 61 by an on-off controllable valve, and the second vapor outlet 212 being connected to the vapor outlet main channel 5 by an on-off controllable valve.
The liquid input main channel is connected with the liquid channel of the steam generation unit through a one-way valve so as to prevent high-pressure steam from reversely flowing to the liquid input main channel. The fluid channel comprises a liquid channel and a gas channel which are communicated with each other, the liquid channel and the gas channel are spiral pipelines, the liquid channel and the gas channel are the front part and the rear part of the same physical channel, and the inner diameter of the gas channel is larger than that of the liquid channel. The gas channel is a spiral pipeline capable of bearing pressure and containing steam, and the generated steam is accumulated in the gas channel of the steam generating unit in the steam accumulating state
Referring to fig. 1 and 2 with an emphasis, any one of the first steam generating unit 1 and the second steam generating unit 2 stops generating steam in its steam discharging state. I.e. the steam generating unit in the exhaust state does not generate steam. Thus, the problem that the quality of steam is difficult to control when the steam is generated and discharged can be avoided. The steam generation is stopped specifically that the steam generation unit does not input liquid and the heating body does not work. The steam generating unit in a state of storing steam generates steam, specifically, the steam generating unit inputs liquid and the heating body works, and the steam outlet of the steam generating unit is closed. The steam outlet of the steam generating unit in the state of storing steam is closed, so that the fluid channel of the steam generating unit forms a closed space, and the generated steam can be stored to reach a certain pressure, thereby having a higher pressure when the steam is discharged.
The steam discharging state of the first steam generating unit 1 and the steam discharging state of the second steam generating unit 2 of the steam generating system are alternately performed, and the steam storing state of the first steam generating unit 1 and the steam storing state of the second steam generating unit 2 are alternately performed. That is, for each steam generating unit, the water inlet, the heating and the steam generation and the steam discharge are performed intermittently, and the combination of the two steam generating units enables the water inlet, the heating and the steam generation and the steam discharge of the whole steam generator to be performed continuously. In order to ensure the continuity of the steam output, in the present embodiment, the duration of the steam storage state of one of the first steam generation unit 1 and the second steam generation unit 2 is equal to the duration of the steam discharge state of the other. By reasonably matching the heating power and the steam generation amount of the heating body, the duration of each steam storage state is equal to the duration of each steam discharge state.
Further, in the present embodiment, the first steam outlet 112 and the second steam outlet 212 are switchably connected to the main steam discharging passage 5 through a two-position three-way valve 3 for discharging steam. As shown in fig. 1, the valve element 31 of the steam discharging two-position three-way valve 3 is located at the first steam outlet 112 of the first steam generating unit 1 at this time, that is, the first steam outlet 112 is closed and not communicated with the steam discharging main passage 5, and the second steam outlet 212 of the second steam generating unit 2 is communicated with the steam discharging main passage 5; at this time, the steam storage state of the first steam generation unit 1 is the steam discharge state of the second steam generation unit 2. As shown in fig. 2, the valve element 31 of the steam discharging two-position three-way valve 3 is located at the second steam outlet 212 of the second steam generating unit 2 at this time, that is, the second steam outlet 212 is closed so as not to communicate with the steam discharging main passage 5, and the first steam outlet 112 of the first steam generating unit 1 communicates with the steam discharging main passage 5; in this case, the steam storage state of the second steam generation unit 2 is the steam discharge state of the first steam generation unit 1. The state shown in fig. 1 and the state shown in fig. 2 are realized by controlling the switching of the position of the spool 31 of the steam discharge two-position three-way valve 3.
Similarly, the first steam generating unit 1 has a first liquid inlet 111 for inputting liquid, the second steam generating unit 2 has a second liquid inlet 211 for inputting liquid, and the first liquid inlet 111 and the second liquid inlet 211 are switchably communicated with the liquid input main channel 61. Specifically, the first liquid inlet 111 and the second liquid inlet 211 are switched by the liquid-feeding two-position three-way valve 4, so that the first liquid inlet 111 and the second liquid inlet 211 alternately feed liquid through the liquid-feeding main channel 61. The liquid-intake two-position three-way valve 4 has a valve spool 41, similarly to the vapor-discharge two-position three-way valve 3, which is switched between the first liquid inlet 111 and the second liquid inlet 211 by controlling the valve spool 41 to effect switching of the water intake processes of the first vapor generation unit 1 and the second vapor generation unit 2.
And in the water inlet process, heating bodies are started to heat, namely the first steam generation unit 1 and the second steam generation unit 2 respectively comprise a fluid channel and a heating body, wherein the heating body is configured to heat and evaporate liquid entering the fluid channel of the steam generation unit into steam when the steam generation unit is in a steam storage state, and the generated steam is stored in the fluid channel of the steam generation unit when the steam generation unit is in the steam storage state. The heating bodies of the first steam generation unit 1 and the second steam generation unit 2 alternately perform heating operation corresponding to the water inlet process. The first heating body 12 and the second heating body 22 are alternately operated so that the total heating power of the heating bodies is not increased at any one time, and the generated steam has a high pressure due to the pressurized process in the steam storage state.
It should be noted that the on-off switching between the first steam outlet 112 and the second steam outlet 212 and the steam discharging main passage 5, and the on-off switching between the first liquid inlet 111 and the second liquid inlet 211 and the liquid inputting main passage 61 are realized by two-position three-way valves. In other embodiments, the inlets and outlets may be respectively provided with an electric control valve, and the on-off state of the electric control valve is controlled by the control signal of the controller to meet the requirements of steam exhaust and steam storage, for example, when the first steam outlet 112 and the second steam outlet 211 are controlled to be opened, the first steam inlet 111 and the second steam outlet 212 are controlled to be disconnected; when the first vapor outlet 112 and the second liquid inlet 211 are controlled to be disconnected, the first liquid inlet 111 and the second vapor outlet 212 are opened.
The above description has been made taking two steam generating units as an example. In other embodiments, the steam generating system may also include 3 or more steam generating units. The control mode can be that a plurality of steam generating units sequentially exhaust steam, or a plurality of steam generating units simultaneously exhaust steam and simultaneously store a plurality of steam.
When the steam generator is in operation, one of the steam generating units is controlled to be in a steam discharging state communicated with the main steam discharging channel to discharge steam, and the other steam generating unit is controlled to be in a steam storing state disconnected with the main steam discharging channel and storing steam;
When the steam is exhausted, the fluid channel of the steam generating unit is disconnected with the liquid input main channel, and the heating body of the steam generating unit stops heating;
and in the steam storage state, the fluid channel of the steam generation unit is communicated with the liquid input main channel, and the heating body of the steam generation unit starts heating work.
The application also provides a steam cleaning device comprising a steam generating system as described in any of the above. Further, the steam generating unit is flat, and has a thickness dimension smaller than a width and length dimension thereof, and the steam cleaning apparatus includes a housing in which the plurality of steam generating units are disposed in a stacked manner in a thickness direction thereof. The arrangement of the steam generating unit is convenient, and the space in the shell can be fully utilized.
As is apparent from the above description of the specific embodiments, the present application provides a steam generation system having a plurality of steam generation units, one of which is in a steam discharge state in which it communicates with a steam discharge main passage to discharge steam, and the other of which is in a steam storage state in which it is disconnected from the steam discharge main passage and stores steam; the steam is continuously output through the alternate exhaust and storage of the steam generating units, and the steam generated by the steam storage state steam generating units is in a relatively closed environment so as to increase the pressure, so that the output steam has higher pressure and the heating power of the steam generating units is not required to be increased.
