[0019] The present application embodiment provides a soaking device 10, see Figure 1 , Figure 1It is a structural schematic diagram of an embodiment of the soaking device of the present application. The soaking device 10 includes a first cylinder 110 and a second cylinder 120, the first cylinder 110 is accommodated inside the second cylinder 120, and a soaking space 101 is formed between the first cylinder 110 and the second cylinder 120. The soaking space 101 is arranged in an annular shape around the first cylinder 110, and a coil 130 is arranged in the soaking space 101. The coil 130 is arranged around the first cylinder 110, and steam can be passed into the coil 130 to transfer heat to the liquid in the soaking space 101. The annular soaking space 101 formed by the first cylinder 110 and the second cylinder 120 in the present application can be used for soaking and cleaning of some annular devices. For example, the screen basket used in the pulp production process, its screen holes will be gradually blocked by pulp fibers, affecting its dehydration effect. The cross section of the screen basket is usually annular. If an ordinary cylinder is used for soaking, a large amount of detergent and clean water will be consumed, and a large amount of energy will be consumed for liquid heating. The annular immersion space 101 in the present application can be used to accommodate the screen basket. The interior of the first cylinder 110 is a hollow area and does not require immersion, which greatly reduces the use of cleaning agents and water. At the same time, due to the reduction in the volume of the liquid to be heated, it is also beneficial to increase the heating rate of the liquid in the immersion space 101, improve efficiency, and save energy.

[0020] Optionally, the first barrel 110 and the second barrel 120 may be cylindrical in shape, and the cross-sectional area of ​​the first barrel 110 is smaller than the cross-sectional area of ​​the second barrel 120. In actual production, the screen basket is usually formed into a ring by splicing and fixing two semicircular rings with bolts. When cleaning is required, the screen basket can be disassembled into semicircular rings and placed in the immersion space 101 together. The annular curvature of the screen basket can correspond to the annular curvature of the immersion space 101, while the screen basket is fully immersed, the volume occupied by the immersion space 101 is reduced.

[0021] Furthermore, the coil 130 can spirally surround the first cylinder 110 multiple times at different heights to expand the contact area with the liquid in the immersion space 101. Steam can be introduced into the coil 130, and when the steam flows along the coil 130, it can exchange heat with the liquid in the immersion space 101, heat the liquid in the immersion space 101, and increase the immersion temperature.
