In the implementation of the byproduct steam device provided by the invention, when no water is in the water supply cavity 602 at first, under the action of the self gravity of the first floating ball 6021, the gear ring 801 rotates, so that the turntable 802 rotates, and thus the sliding block 702 is pressed down on the valve seat 700 under the linkage action of the push-pull rod 701 so as to block the circulating pipe 502; then, the soft water inlet 501 is connected to a soft water supply system, so that soft water in the soft water tank 500 is continuously added into the steam drum 400 through the soft water inlet, and the pump body 404 which operates synchronously is utilized, so that the soft water in the soft water tank 500 is continuously added into the steam drum 400, the first conduit 402 in the invention is a down pipe, and the soft water in the steam drum 400 is circularly added into the soft water supply tank 600 through the first conduit 402, the soft water in the steam drum 400 is firstly supplemented into the water supply cavity 602 through the water distribution assembly, at this time, due to the arranged on-off valve, the soft water also exists in the flow cavity 601, after the water in the water supply cavity 602 overflows the second floating ball 608, the on-off valve is closed, then the water distribution assembly is continuously adjusted, so that the soft water introduced through the first conduit 402 is added into the flow cavity 601, and as the water in the flow cavity 601 is full, the soft water in the flow cavity 601 continuously overflows to enter the water supply cavity 602 through the top cavity, and as the water level in the water supply cavity 602 is increased, the flow rate control valve is gradually opened; so that a part of the water in the flow chamber 601 continuously overflows into the water supply chamber 602, and a part of the water enters the soft water tank 500 through the circulation pipe 502 and is circulated into the steam drum 400.
The synthesis furnace main body 100, which is operated synchronously at this time, continuously evaporates water in the jacket 200 to form steam, and the steam enters the steam drum 400 through the steam communicating tube 201 to be separated.
Further, when the water level in the jacket 200 drops to the early warning water level, the first floating ball 6021 moving downward reduces the flow rate of the flow rate control valve, so that more water in the flow chamber 601 enters the water supply chamber 602, and when the water in the water supply chamber 602 continuously drops to a level lower than the second floating ball 608, at this time, the on-off valve is turned on, a communicating device is formed between the flow chamber 601 and the water supply chamber 602, so that the water in the flow chamber 601 quickly enters the water supply chamber 602 to distribute water to the water supply chamber 602 in time and quickly, thereby avoiding the influence on the continuous operation of the byproduct steam device when the soft water supply system temporarily stops supplying water, providing sufficient time for a worker to find out the problem of water shortage, and avoiding the burnout of the synthesis furnace main body 100 caused by water shortage.
It can be understood that, in the invention, water is added into the flow cavity 601, and part of the water in the flow cavity 601 overflows into the water supply cavity 602, so as to realize the effect of supplementing water into the water supply cavity 602, and avoid the problem of rapid water shortage in the jacket 200 caused by the problem of the soft water supply system, at this time, the water in the flow cavity 601 can be temporarily supplemented into the water supply cavity 602, so as to maintain the by-product steam device to be used for a longer time; in addition, the invention can automatically adjust the flow rate of the flow rate control valve according to the water level height in the water supply cavity 602 in real time, and automatically adjust the overflow water supply rate of the flow cavity 601 to the water supply cavity 602.
Further, as shown in fig. 1 to fig. 3, in the embodiment of the present invention, the water distribution assembly includes a gas distribution plate 900 rotatably disposed in the top cavity, a water distribution port 901 is disposed at one side of the gas distribution plate 900, an inner cavity of the soft water supply tank 600 above the gas distribution plate 900 is a water distribution cavity 603, and the first conduit 402 extends into the water distribution cavity 603.
Further, in the embodiment of the present invention, the water distribution assembly further includes a servo motor 902 for driving the air distribution disc 900 to rotate, a driving gear 905 is installed on an output shaft of the servo motor 902, a rotating sleeve 903 is coaxially and fixedly installed on the air distribution disc 900, a driven gear 904 engaged with the driving gear 905 is installed on the rotating sleeve 903, and when the servo motor 902 is started, the rotating sleeve 903 can be driven to rotate.
Further, as shown in fig. 7, in the preferred embodiment of the present invention, the rack 803 is coaxially inserted into the rotating sleeve 903.
Further, in the preferred embodiment of the present invention, the soft water supply tank 600 further has an air pressure balancing hole 607 communicating with the top chamber at the top thereof.
