[0032] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model and are not limited to the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0033] like Figures 1 to 3 , which is a schematic diagram of the structure of an embodiment of the utility model, provides a steam absorber for a steam explosion material receiving bin, including an absorber bin body 1 and a plurality of buffer baffles 2 arranged in the absorber bin body 1.

[0034] The storage tank body 1 is a hollow columnar structure, and the first end of the storage tank body 1 in the length direction is open and connected to the exhaust port 5-1 of the material receiving tank 5 (such as Figure 5 As shown), a plurality of air outlet holes 1-1 are provided at the second end of the absorber bin body 1.

[0035] In this example, the absorber bin body 1 adopts a cylindrical structure, a sealing plate 4 is provided at the second end of the absorber bin body 1, and a plurality of air outlets 1-1 are provided on the side wall of the absorber bin body 1 near the sealing plate 4. The sealing plate 4 is a curved plate member protruding to the outside of the absorber bin body 1, so that the inside of the absorber bin body 1 is a smooth structure without dead angles, which is convenient for cleaning.

[0036] The plurality of air outlet holes 1 - 1 are arranged in a rectangular array and along the circumference of the absorber chamber body 1 . In this example, the plurality of air outlet holes 1 - 1 partially cover the side wall of the absorber chamber body 1 in the circumference of the absorber chamber body 1 .

[0037] A plurality of buffer baffles 2 are fixed on the inner wall of the absorber bin body 1 and are arranged in an interlaced manner along the length direction of the absorber bin body 1. A plurality of air holes 2-1 are provided on the buffer baffles 2, so that a curved airflow channel is formed between the plurality of buffer baffles 2, which can perform secondary buffering on the high-speed shock wave generated by the steam explosion. At the same time, the buffer baffles 2 can intercept and recover particles or droplets in the airflow, reduce dust discharge, and meet environmental protection requirements.

[0038] In this example, the buffer baffle 2 is semicircular (eg Figure 4 As shown in the structure, the radius of the buffer baffle 2 is the same as that of the absorber bin body 1, that is, a plurality of buffer baffles 2 are circularly arranged on the axis of the absorber bin body 1. In other embodiments, the buffer baffle 2 can also be a fan-shaped structure.

[0039] In order to facilitate the installation of the absorber bin body 1 on the material receiving bin 5, a connecting flange 3 is provided at the first end of the absorber bin body 1 in the length direction, and the connecting flange 3 extends radially outward from the outer wall of the absorber bin body 1. A plurality of positioning holes 3-1 are provided on the connecting flange 3. Preferably, the plurality of positioning holes 3-1 are evenly spaced along the circumference of the connecting flange 3, and the connecting flange 3 is connected to the material receiving bin 5 by bolts, so that the absorber is fixed to the exhaust port 5-1 of the material receiving bin 5.

[0040] The working principle of the utility model is:

[0041] After the high-speed airflow from the steam explosion carries the material into the material receiving bin 5, it undergoes primary deceleration and reflection from the bin wall, and the remaining impact airflow and tiny material particles enter the absorber bin body 1 through the exhaust port 5-1. The material particles are intercepted in batches when passing through each buffer baffle 2, and the airflow is decelerated after bypassing the buffer baffle 2. At the same time, the water vapor droplets in the airflow are blocked and condensed. Finally, after multiple turns and interceptions, the high-speed airflow is buffered and decelerated and then discharged from the absorber bin body 1 through the multiple air outlets 1-1 at the second end of the absorber bin body 1. The steam droplets in the airflow and the particles carried by them are intercepted on the buffer baffle 2 and finally fall back into the material receiving bin 5.

[0042] In summary, the steam absorber can provide secondary buffering for the high shock wave generated by steam explosion, while intercepting particles or droplets in the airflow to achieve gas-solid separation and steam absorption.

[0043] The above examples are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
