Detailed Description
Example 1
The fully automatic gas-fired hot water steam generating system described in this embodiment 1, as shown in fig. 1, includes a gas burner 9, a heating device above the burner, and an exhaust fan 12 for exhausting tail gas of gas combustion, and is characterized in that: the heating device comprises: a steam box 1 above the burner and heated; a hollow fire tube 10 with one end opening facing the flame of the burner and penetrating through the steam box 1 is arranged in the steam box; a water inlet 6 and a steam outlet 5 are arranged on one side of the steam box, and a hot water outlet 14 and a water supplementing sensor 2 are arranged on the other side of the steam box; a wave board 4 is erected in the steam box, the wave board and the upper top and the lower bottom of the inner cavity of the steam box are spaced, the inner cavity of the steam box is divided into a steam generating cavity containing a hollow fire tube, a water inlet 6 and a steam outlet 5, and a water level control cavity containing a water supplementing sensor 2 and a hot water outlet 14, and a steam box shell above the steam generating cavity is provided with a safety exhaust valve 15 and a high-temperature automatic shutdown controller 16;
the water supplementing sensor 2 is arranged in the water level control cavity and is used for timely transmitting signals to the control console 20 to control water supplementing when the water level is too low; an anti-overflow sensor 19 is arranged for controlling the water level in the steam box and preventing the overflow of hot water from the steam outlet due to the overhigh water level;
further, a waste heat recovery water tank 13 is arranged below the steam box, the waste heat recovery water tank is connected with a water inlet 6 of the steam box through a pipeline, a tap water inlet 7 is arranged at the lower part of the waste heat recovery water tank, and an anti-overflow electronic valve 21, a water supplementing electronic valve 3 and a tap water filter 8 are sequentially arranged between the tap water inlet and a tap water pipe; the waste heat recovery pipes 11 which correspond to the number of the hollow fire pipes and are communicated with one-to-one corresponding pipelines are arranged through the waste heat recovery water tank, and an exhaust fan 12 is arranged at the outlet of each waste heat recovery pipe.
Further, the fully automatic gas-fired hot water steam generating system is also provided with a control board 30, and the control board is connected with a power supply and a control system of the water-overflowing preventing sensor 19, the water-overflowing preventing sensor 2, the water-overflowing preventing electronic valve 21, the water-overflowing preventing electronic valve 3 and the burner.
In addition, the tap water inlet 7 is arranged at the bottom of one end of the waste heat recovery water tank, and the position of the water inlet 6 connected with the steam box is arranged at the top of the other end of the waste heat recovery water tank.
In addition, the steam outlet 5 is respectively connected with a warmer 21, a meal steaming and dish sterilizing device 22, a steam shower room 23 and the like.
Therefore, after the full-automatic gas hot water steam generation system is started, the water supplementing sensor transmits the water level condition to the control board, if water is lack, the control board outputs and controls the water supplementing electronic valve to be started until the minimum required water level, and then the control board is connected with the protection switch of the corresponding burner, so that the burner can be started to burn so as to heat water in the steam box and generate steam; when the water level rises to trigger the anti-overflow sensor, the induction signal control board outputs a signal to control the water supplementing electronic valve to be closed; the generated steam is discharged out of the steam box through the steam outlet pipe, and the generated hot water can be discharged from the hot water outlet. When the burner is turned on, the exhaust fan is simultaneously started. The waste gas and the waste heat generated by the combustion of the burner enter the inlet of the hollow fire tube and enter the waste heat recovery tube through the pipeline and are discharged from the exhaust fan under the driving of the exhaust fan, so that the waste gas and the waste heat are transferred to cold water in the waste heat recovery water tank to heat the waste gas and the waste heat when passing through the waste heat recovery tube. Through such heat transfer, the temperature at the outlet of the waste heat recovery pipe can be reduced to be slightly higher than the atmospheric temperature (namely tap water temperature), so that the waste heat recovery pipe can be safely discharged outside the exhaust fan, and the discharged gas is low in temperature, so that no heat is influenced and destroyed to the outside, and fire hazards are avoided.
The safety exhaust valve has the function of automatically opening the steam box shell to rapidly exhaust high-pressure steam when the internal pressure of the steam box shell is too high in case of blockage of a steam outlet pipeline and the like, so that the safety of the steam box shell is prevented from being influenced by explosion caused by high pressure. The wave board of preventing standing inside the steam chest, its effect is with the steam chest inner chamber partition out independent space give the water level response original paper, so can prevent when burning that high temperature from producing steam bubble and unrestrained the stream of water and scurrying the space that strikes water level sensor place, guaranteed moisturizing inductor and anti-overflow water sensor normal operating condition, avoided producing the error signal and lead to the control panel maloperation.
The above description is only of the preferred embodiment of the present invention, and is not intended to limit the structure of the present invention in any way. Any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
