Most of the existing steam heaters are pipeline heaters, which heat the regulating tank, especially a large-capacity regulating tank, too slowly, with too low efficiency and excessive energy waste, thus causing too high costs for enterprises, raising the enterprise costs and reducing the profit margin.

[0003] The utility model patent with the application number: CN202322749753.X and the publication number: CN221444890U (hereinafter referred to as "Prior Art 1") discloses a steam heating high-temperature hot water circulation system, the structure of which includes a water inlet assembly, a heating chamber, a heating element, and a water circulation assembly; the water inlet assembly is connected to the heating chamber for water replenishment; the heating element is connected to an air inlet pipe communicating with steam; the water in the heating chamber exchanges heat with the heating element to increase the temperature.

[0004] The specification of Prior Art 1 discloses a steam heating high-temperature hot water circulation system. When in use, the water is heated by steam heating, and the steam can be introduced from a boiler. In this way, the heating cost is lower than that of electric heating, and the heat conversion rate is greater than that of direct combustion heating, reducing heat loss; however, in actual applications, in a large regulating tank, the heating speed is slow, the heating efficiency is low, and a lot of heat energy will be wasted. Summary of the Invention

[0005] The utility model provides a steam heating rotary diffuser device for a regulating tank, aiming to solve the problems of slow heating speed, low efficiency and heat energy waste in the use of the existing steam heating device.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A steam heating rotary diffuser device for a regulating tank includes a housing for installation inside a sewage tank: a rotary cylinder is rotatably installed inside the housing, and a jacket is formed between the housing and the rotary cylinder;

[0008] The jacket is provided with a steam inlet and a steam outlet. The steam inlet is used for introducing high-pressure steam to drive the rotary cylinder to rotate, and the steam outlet is used for discharging the high-pressure steam;

[0009] Among them, a nozzle is provided at the bottom of the rotating cylinder, and the nozzle is used to inject steam into the rotating cylinder.

[0010] Furthermore, the jacket is a spiral structure.

[0011] Furthermore, steps are provided on both the inner wall of the housing and the outer wall of the rotating cylinder, and the steps on the housing match and rotate with the steps on the rotating cylinder.

[0012] Furthermore, a sealing ring is provided on the step, and the housing and the rotating cylinder are rotationally and sealingly connected.

A rotating cylinder is rotatably installed inside the housing, and a jacket is formed between the housing and the rotating cylinder. During actual use, the nozzle is located at the inlet of the rotating cylinder, and steam or compressed air is ejected at high speed through the nozzle. According to Bernoulli's equation, the principle that where the flow velocity is large, the pressure is small, a negative pressure is formed at the inlet of the rotating cylinder, which generates a strong suction force on the sewage in the entire sewage tank, driving the sewage in the sewage tank to circulate rapidly. In this process, after the sewage is ejected from the outlet of the rotating cylinder, the sewage at the bottom of the sewage tank is attracted by the inlet of the rotating cylinder under the action of the negative pressure, realizing the rapid circulation of the sewage. Since the inner wall of the rotating cylinder has an inner cone angle, steam enters the jacket through the steam inlet of the jacket, and the steam is ejected at high speed from the steam outlet, driving the rotating cylinder with rotating fins to rotate through the action and reaction forces, increasing the heat exchange efficiency of the sewage in the sewage tank per unit time, and significantly improving the heat exchange speed and efficiency, thereby realizing the rapid heating of the sewage in the sewage tank and ensuring the normal operation of the subsequent biochemical system.
