The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Specific example I:
The present embodiment provides an embodiment:
Referring to fig. 1, a solid amine desorption apparatus includes: a first housing 1, a second housing 2, a heating assembly 3, a steam generating unit 4, and a vacuum pump 9; wherein the second housing 2 is coaxially and rotatably arranged inside the first housing 1 for receiving solid amine particles to be desorbed; a heating assembly 3 is arranged in communication with the heating spaces of the first housing 1 and the second housing 2 for heating the solid amine particles to be desorbed so as to cause desorption; the length of the second shell 2 is 3.5-5.5m, and the inner diameter is 1.5-2.5m; what needs to be clarified is: a material buffer bin is shown at B in FIG. 1;
The traditional desorption device is usually fixedly arranged, and solid amine particles are blown up and heated by means of air flow and the like, so that the desorption efficiency is improved; however, when encountering defects such as breaking, caking, etc. of the solid amine, the air flow cannot be precisely controlled, and excessive consumption of energy or poor desorption effect is easily caused, and based on this, in this embodiment, the second housing 2 includes: a second housing body 201 and at least 2 flow directors 203; the flow guiding members 203 are uniformly distributed on the outer side of the second housing body 201 along the axial direction of the second housing body 201, and are configured to match the heating assembly 3, so as to adjust the airflow speed of the heating space; when in use, the second shell body 201 drives the flow guide piece 203 to rotate to form rotary air flow, so that the flow speed of the air flow is improved, and the heating efficiency is increased; meanwhile, since the solid amine particles are located inside the second housing body 201, if the agglomeration or the like occurs, the second housing body 201 is broken by the rotation, and the desorption effect is not affected.
In this example, different implementations are provided for the baffle:
Alternatively, as shown in fig. 2-3, the flow guide 203 is in a flat plate shape; the height of the end, away from the heating component 3, of the flow guiding piece 203 is smaller than that of the end, close to the heating component 3, of the flow guiding piece 203; through the guide members 203 in the present embodiment, the height of the guide members 203 near one end of the heating assembly 3 is higher, at this time, the air flow forms a rotating air flow between the two guide members 203, the flow speed is faster, and the air flow rapidly enters the distal end of the heating assembly 3, at this time, the space between the guide members 203 and the first housing 1 is enlarged due to the smaller height of the guide members 203 near one end of the heating assembly 3, so as to form a larger space; when the flow guide member 203 rotates, vortex is formed between the flow guide member 203 and the first shell 1 at the far end of the heating assembly 3, so that heat is accumulated at the far end of the heating assembly 3, heating balance between the heated near end and the far end can be ensured under the condition that transmission loss exists in the heating assembly 3, and heating effect is improved;
Optionally, the guide 203 is curved, as shown in fig. 4-5, preferably S-shaped, and the rotation direction of the guide 203 is consistent with the rotation direction of the second housing 2; in a specific use, the air flow in the heating space is formed into a rotating air flow by rotating the S-shaped curved guide piece 203, so that the flow speed is increased, the temperature difference between the heating near end and the heating far end of the heating component 3 is reduced, and the heating effect is improved;
Since the second housing 2 is rotatable, the heating assembly 3, for cooperation therewith, comprises: a heat source 301 and an air intake mechanism 302; one end of an air inlet mechanism 302 is connected with the heat source 301, and the other end is connected with the heating space, and is used for adjusting the air inlet amount of the air inlet mechanism 302 according to the temperature in the second shell 2 and adjusting the air flow in the heating space under the combined action of the air inlet mechanism and the flow guide 203;
