Fig. 1 is a schematic structural diagram of a boiler feed water deaerating plant for a prebaked anode production plant according to an embodiment of the present application. The embodiment of the present application provides a boiler feed water deaerating apparatus for a prebaked anode production plant, as shown in fig. 1, comprising a tank 100, a heater 200, a liquid level sensor 300, a deaerating pipeline 400, a demister 500 and a controller (not shown in the figure), wherein the tank 100 is made of steel material and is used for containing feed water. The heater 200 heats the feed water in the tank 100 to evaporate the feed water at a predetermined temperature, thereby carrying out oxygen contained in the feed water. The level sensor 300 is used to measure the level of the supply water in the tank 100. The demister 500 serves to reduce the content of supply water in the steam. The controller is used for controlling the apparatus and may be installed on the outer wall of the can 100 for user's operation.

As shown in fig. 1, the liquid level sensor 300 is disposed on the inner wall of the tank 100 for detecting the level of the liquid. The deoxidizing pipe 400 is connected to the top of the tank 100, and the deoxidizing pipe 400 should be provided with an air outlet, so that the supply water enters the deoxidizing pipe 400 after being evaporated and is finally discharged from the air outlet.

The demister 500 is disposed in the oxygen removal pipe 400, and when steam enters the oxygen removal pipe 400 and passes through the demister 500, the demister 500 separates droplets of supply water entrained in the steam, thereby reducing the content of the supply water in the steam, and reducing the content of the supply water discharged from the tank body 100.

The controller is electrically connected with both the heater 200 and the liquid level sensor 300, when the liquid level detected by the liquid level sensor 300 is lower than a preset liquid level, a signal can be sent to the controller, and the controller controls the heater 200 to be closed after receiving the signal, so that the heater 200 is prevented from being burnt.

Of course, the tank 100 should also be provided with a feed water inlet conduit and a feed water outlet conduit, which will not be described in detail herein.

Compared with the prior art, the boiler feed water deoxygenation device realizes the function of deoxygenating the feed water through the heater 200 and the deoxygenation pipeline 400. Reduce the supplied water content that the steam brought out through demister 500 to reduce the content of supplied water discharge tank body 100, detect the liquid level in the tank body 100 through setting up level sensor 300, if be less than predetermined liquid level, then send the signal to the controller, the controller receives signal back control heater 200 and closes, thereby prevents that heater 200 from burning futilely, has reduced the potential safety hazard.

In some embodiments, as shown in fig. 1, the heater 200 includes a power source 210 and heating wires 220 electrically connected to the power source 210, the heating wires 220 are disposed near the bottom of the can 100, and the power source 210 may be generally disposed on the outer wall of the can 100 and electrically connected to the heating wires 220 through a power cord. The controller is electrically connected to the power supply 210, and controls whether the heating wire 220 heats or not by controlling the power supply 210 to be turned on or off.

Fig. 2 is a schematic structural diagram of an electric heating wire used in a boiler feed water deaerator for a prebaked anode production plant according to an embodiment of the present application. In order to improve the heating efficiency of the heating wire 220, in some embodiments, as shown in fig. 2, the heating wire 220 is formed by alternately connecting a plurality of straight segments 221 and semicircular segments 222 in sequence, so that the contact area between the heating wire 220 and the supplied water is increased, and when the heating wire 220 operates, the supplied water at a plurality of positions can be simultaneously heated, thereby improving the heating efficiency of the heating wire 220.

In some embodiments, as shown in fig. 1, the position of the heating wire 220 is flush with the position of the preset liquid level, and when the liquid level detected by the liquid level sensor 300 is lower than the preset liquid level, i.e., the liquid level is lower than the position of the heating wire 220, the controller turns off the heating wire 220, thereby preventing the heating wire 220 from being dried.

In order to utilize the heat in the oxygen and improve the heat utilization rate, in some embodiments, as shown in fig. 1, a heat exchanger 600 is further included, the heat exchanger 600 is communicated above the oxygen removal pipeline 400, and the heat exchanger 600 is communicated with the tank 100 through an outlet pipe 620. The heat exchanger 600 has an inlet pipe 610 and an outlet pipe 620, and the cooling water enters from the inlet pipe 610 and exchanges heat with the high-temperature oxygen, so that the temperature of the oxygen is reduced, the temperature of the cooling water is increased, the high-temperature oxygen is prevented from being directly discharged into the air, the cooling water after the temperature is increased enters the tank body 100 through the outlet pipe 620, the heat in the oxygen is utilized, and the effect of supplementing the water can be also played.

In some embodiments, as shown in fig. 1, the heat exchanger further includes an evacuation pipe 700, the evacuation pipe 700 communicates with the upper side of the heat exchanger 600, and an evacuation valve 710 is disposed on the evacuation pipe 700. The oxygen passing through the heat exchanger 600 enters the evacuation pipe 700 and is discharged to the air from the evacuation pipe 700. An evacuation valve 710 on the evacuation pipe 700 can control the on/off of the evacuation pipe 700, thereby controlling whether oxygen is discharged.

To avoid impurities from entering the evacuation tube 700, in some embodiments, as shown in fig. 1, the upper end of the evacuation tube 700 is curved, with the outlet of the evacuation tube 700 facing downward. The possibility that impurities fall into the emptying pipe 700 can be greatly reduced by arranging the outlet downwards, so that the possibility that the emptying pipe 700 is blocked is reduced, and smooth discharge of oxygen is ensured.

In some embodiments, as shown in fig. 2, a filter screen 720 is disposed at an outlet of the evacuation pipe 700, so as to further prevent impurities from entering the evacuation pipe 700, further reduce the possibility of impurities entering the evacuation pipe 700, further reduce the possibility of blockage of the evacuation pipe 700, and achieve a good practical effect.

In order to periodically discharge the contaminants in the tank 100, in some embodiments, as shown in fig. 1, a soil discharge pipe 110 is provided at the bottom of the tank 100. The user can wash and drain the tank 100 periodically through the drain pipe 110 to keep the supply water clean.
