[0030] Working principle:

[0031] When steam enters the tank body from the steam inlet pipe, water will impact the surface of the baffle plate, and then flow downward along the baffle plate due to gravity, and fall to the bottom of the tank body, and accumulate at the bottom of the tank body. At this time, if the condensed water still has considerable heat, it will continue to evaporate and move upward in the tank body and flow out from the exhaust pipe. When the amount of water accumulated at the bottom of the tank body is too much, the electronic liquid level meter detects that the liquid level is higher than the through hole by a certain distance, about 5cm. At this time, it can be understood that the water in the drain pipe between the electronic valve is full, and the electronic liquid level meter sends a signal to the PLC control system, and the PLC control system opens the electronic valve. Due to the siphon principle caused by pressure difference, the water accumulated at the bottom of the tank body will flow out from the drain pipe at one time, and the electronic liquid level meter detects that the liquid level is lower than the through hole by a certain distance, preferably after being drained, and sends a signal to the PLC control system to close the electronic valve. Repeat the above steps to realize continuous heat energy recovery. The baffle plate arranged in a wavy and inclined manner not only helps to increase the baffle area, but also makes the airflow speed in the upper part of the outer chamber slow, preventing a small amount of steam from escaping from the drain pipe due to siphon pressure difference.

[0032] The embodiment also introduces a ring-shaped steam inlet manifold and multiple steam inlets, high-pressure steam in the steam inlet pipe enters along the ring-shaped steam inlet manifold from the multiple steam inlets, which is conducive to realizing stable operation of the steam inlet pipe, meanwhile, the pipeline filter, the temperature sensor, the first pressure sensor and the second pressure sensor are electrically connected with the PLC control system, so that the steam inlet process is comprehensively monitored and controlled, the purity and stability of the steam are ensured, and the steam can be timely responded when the pressure is abnormal, and the pressure is released through the emergency pressure relief valve, the ring-shaped steam inlet manifold has a small volume and high pressure resistance, and when the emergency pressure relief is performed, the pressure in the tank body can be quickly reduced through the steam inlets, the safety and reliability of the tank body and the steam inlet pipe are maintained, and the blockage of the pipeline filter can be quickly responded through the pressure difference between the two pressure sensors.

[0033] The above only describes preferred embodiments of the present application, and it should be noted that for ordinary skilled persons in the technical field, several improvements and refinements can be made without departing from the technical principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
