Description
Technical Field
The application belongs to the technical field of auxiliary facilities for after-finishing of textile and clothing, and particularly relates to a steam generating device with steam recovery and steam-liquid separation functions.
Background
The steam generating device with the functions of steam recovery and steam-liquid separation is arranged along with a steam boiler (also called a main boiler and the following is the same) in a use state, is connected and communicated with a steam output pipeline of the steam boiler, and is used as an additional steam supply device or an auxiliary steam supply device of the steam boiler to provide technical support for energy conservation of the steam boiler; typical examples of the above mentioned finishing of textile garments are ironing of the garment or similar needle textile products with a steam iron.
As is known in the art, since a large amount of redundant steam is generated during the operation of the steam iron (i.e. during ironing), if the redundant steam is not recovered, it is undoubtedly wasteful of energy and goes against the current economical and energy-saving spirit advocated by the whole society.
The above-mentioned steam generating devices are not known in the published chinese patent documents, such as CN205388303U (fully automatic electric heating steam generator), CN201093470Y (a kind of air pressure type electric heating steam generator), and CN203771369U (improved electric heating steam generator), and so on. These patents are not limited to the exemplified ones and do not have the function of recovering the surplus steam to embody energy saving.
CN102200273B recommends a "waste heat recovery system for a hybrid energy environmental protection steam generator", which can honor the technical effects described in paragraphs 0013 to 0020 of the specification, but has no implication for recovering redundant steam as a steam generator for finishing textile clothing.
CN106835660a is provided with a "steam heating cycle, steam generating means, and ironing machine", the construction of which is: solves the technical problem that the prior art can not recycle the steam in the muffler. The specific scheme is as follows: the recycling water storage barrel is arranged in the cooling water barrel with an opening at the upper part (the cooling water inlet is called as patent), an air return pipe is connected with an air return pipe inlet arranged at the upper part of the recycling water storage barrel, a water return water outlet at the lower part (bottom) of the recycling water storage barrel is connected with a water return pump through a pipeline, and a cooling water outlet at the bottom of the cooling water barrel is connected with the cooling water pump through a corresponding pipeline. Specific working principles can be seen in paragraphs 0060 to 0061 of this patent specification.
The CN106835660a has the technical effects summarized in paragraph 0014 of the specification, but has the following disadvantages: firstly, the water in the cooling water bucket is heated in a heat transfer mode through the recovery steam introduced into the recovery water storage bucket through the air return pipe, and in the process that the water in the cooling water bucket is heated in a heat transfer mode, namely in a spacer sleeve heating mode, the steam introduced into the recovery water storage bucket from the air return pipe condenses into water, so that links are increased, and larger energy consumption exists; secondly, because the cooling water barrel is in an exposed state, the situation of unavoidable heat diffusion to the outside exists, and thus heat energy loss is also caused; thirdly, because the backwater water pump and the cooling water pump are required to be equipped, the structure is complex, the cost of the whole device is increased, the electric energy consumption is not favorably saved, and the daily maintenance difficulty and the workload are increased.
Needless to say, the zero loss energy of the recovered steam can be said to actually represent an extremely energy saving effect, and it is seen in the published chinese patent literature such as CN206361672U that a "steam generating device" is introduced, which is suitable for a steam iron, that is, excess steam generated by a steam recovery pipe is introduced into a water container, so that the water temperature in the water container is increased, and the electric energy consumption of an electric heating pipe provided at the bottom of the water container to heat and vaporize water is saved, and particularly, see paragraphs 0030 to 0031 of the specification of the patent. This patent faithfully embodies the technical effects described in paragraphs 0021 to 0024 of the specification, but suffers from the following inevitable drawbacks: because the redundant steam is directly returned into the water container (the water container is essentially a steam generating tank) through the steam recovery pipe, and because the water container also generates steam under the operation of the electric heating pipe at the bottom of the water container, when the recovered steam is completely introduced into the water container at one time by the steam recovery pipe, the pressure of the steam in the water container is larger than that of the steam return pipe, so that the steam in the steam recovery pipe cannot enter the water container, and in this case, the effect of the steam recovery pipe is better than that of the steam without even dummy.
The above-mentioned prior art needs to be improved, and the inventor has made beneficial researches and designs for this purpose, and finally, the technical solutions to be described below are formed, and simulation tests are performed in the product test center of the inventor under the condition of taking security measures, so that the results prove to be feasible.

In the present embodiment, the steam device 5 is a steam iron, but not limited to a steam iron, and other similar steam tools suitable for finishing fabrics should be regarded as the category of the steam device 5. Taking the steam using device 5 as an example, the steam using device is provided in this embodiment, the steam using device inlet pipe 51 connects the steam using device inlet pipe connector 2111 with the steam inlet of the steam using device 5, and the steam using device 5, i.e. the redundant steam outlet of the steam iron, is connected by the branch pipe 41.
The steam device 5, namely the steam iron, introduces the redundant steam generated in the process of ironing the clothes into the steam-liquid separation tank cavity 613 through the redundant steam outlet, the branch pipe 41 and the return pipe 4 in sequence, at the moment, the return pipe opening and closing valve 42 (manual operation) arranged on the pipeline of the return pipe 4 is in an open state, and the overflow electromagnetic valve 6121 and the steam-liquid separation tank blow-down valve 6122 are in a closed state. At the same time, the steam in the steam boiler 2 enters the steam device 5, i.e. the steam iron, through the steam output pipeline 21 (the valve 212 arranged on the steam output pipeline 21 is in an open state), the steam shunt pipe 211, the steam device inlet pipe connector 2111 and the steam device inlet pipe 51 in sequence.
Droplets of the recovered steam introduced into the vapor-liquid separation tank chamber 613 through the air return pipe 4 are trapped in the vapor-liquid separation tank chamber 613, and the recovered steam in the vapor-liquid separation tank chamber 613, i.e., the recovered steam from which the droplets are separated, enters the tank chamber 11 through the recovered steam outlet 611, and then forms high-temperature steam under the operation of the electric heating device 3 and is introduced into the aforementioned steam output pipe 21 through the regenerated steam outlet pipe 12 (in the state where the raw steam outlet pipe solenoid valve 121 is opened). In the above process, since one end of the air return pipe 4 is folded down in the vapor-liquid separation tank cavity 613 and the other end of the air return pipe 4 is shielded by the vapor-liquid separation tank 61 and is not directly exposed to the tank cavity 11, the smooth air return of the air return pipe 4 is not affected by the pressure difference that the vapor pressure in the tank cavity 11 is greater than the pressure of the air return pipe 4.
In summary, the technical scheme provided by the application overcomes the defects in the prior art, successfully completes the task of the application, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
