[0025] Reference Figure 1-3 The utility model provides a vortex falling film heat exchanger, which mainly includes:

[0026] Falling film heat exchanger body 100;

[0027] A pair of support structures 200, such as Figure 1, a pair of support structures 200 are both connected to the falling film heat exchanger body 100;

[0028] like Figure 2 The support structure 200 includes a lower clamping plate 201 clamped on the bottom of the falling film heat exchanger body 100, an upper clamping plate 202 clamped on the top of the falling film heat exchanger body 100, and a support seat 203 fixedly connected to the bottom of the lower clamping plate 201, wherein the lower clamping plate 201 and the support seat 203 are integrally connected, which is convenient for production and manufacturing, and the strength between the structures is good, the tops of both sides of the lower clamping plate 201 are fixedly connected with lower ear plates 204, the lower clamping plate 201 and the lower ear plates 204 are integrally connected, which is convenient for production and manufacturing, and the strength between the structures is good, the bottoms of both sides of the upper clamping plate 202 are fixedly connected with upper ear plates 205, the upper clamping plate 202 and the upper The ear plates 205 are connected in an integrated manner, which is convenient for production and manufacturing, and the strength of the structures is good. The lower ear plate 204 and the upper ear plate 205 are movably fitted and fixedly connected by fastening bolts. When the upper ear plate 205 and the lower ear plate 204 are fixedly connected together by fastening bolts, the falling film heat exchanger body 100 can be clamped and fixed between the upper clamping plate 202 and the lower clamping plate 201 at the same time, so that the falling film heat exchanger body 100 can be fixedly connected with the supporting structure 200, and fixed by fastening bolts, and can be disassembled, so that it is convenient to replace the supporting structure 200 separately when it is deformed or damaged, and it is easy to use;

[0029] Two pairs of mobile structures 300, such as Figure 1 , two pairs of mobile structures 300 are symmetrically arranged on the front and rear sides of a pair of supporting structures 200, and are fixedly connected to the supporting structures 200;

[0030] like Figure 3 The mobile structure 300 includes a fixed plate 301 connected to the support seat 203, a hydraulic cylinder 302 fixedly connected to the top of the fixed plate 301 by bolts, a mounting plate 303 located below the fixed plate 301, and a universal wheel 304 fixedly installed at the bottom of the mounting plate 303 by bolts. The piston end of the hydraulic cylinder 302 moves through the fixed plate 301 and is fixedly connected to the top of the mounting plate 303 by bolts. The structures are connected in a detachable manner to facilitate the later repair and maintenance of the hydraulic cylinder 302.

[0031] Specifically, Figure 3The fixing plate 301 has a slot 305 on one side, and the slot 305 is adapted to engage with the side of the support seat 203. When engaged, the inner bottom wall of the slot 305 abuts against the side of the support seat 203. The fixing plate 301 and the support seat 203 are fixedly connected by fastening bolts, that is, the fixing plate 301 and the support seat 203 are both provided with through holes adapted to the fastening bolts. The fixing plate 301 is fixed by the fastening bolts and can be disassembled. Therefore, when the damaged support structure 200 is replaced, the mobile structure 300 can be disassembled and reused, which can reduce the replacement cost. The left and right sides of the support seat 203 are fixedly connected to the bottom of the fixing plate 301 with positioning plates 206. The upper surface of the positioning plate 206 is movably fitted with the lower surface of the fixing plate 301. By setting the positioning plate 206 (such as Figure 2 ), the engagement height of the fixing plate 301 can be quickly positioned so that the fixing holes on the fixing plate 301 can quickly correspond to the fixing holes on the support seat 203, thereby improving the installation efficiency.

[0032] In summary, when it is necessary to replace the damaged support structure 200, first support the falling film heat exchanger body 100 through the temporary support device, then remove the fastening bolts on the upper ear plate 205 and the lower ear plate 204, and then drive the lower clamping plate 201 downward through the support seat 203 to separate the lower clamping plate 201 from the falling film heat exchanger body 100. After separation, remove the upper clamping plate 202 from the falling film heat exchanger body 100, and then install the new support structure 200 to the bottom of the falling film heat exchanger body 100 through the fastening bolts. The overall operation is simple, and the damaged support structure 200 can be replaced alone. After replacing the support structure 200, the movable structure 201 can be moved to the bottom of the falling film heat exchanger body 100. The structure 300 is disassembled and fixedly installed together with the new supporting structure 200, which can reduce the replacement cost; when the falling film heat exchanger body 100 needs to be moved, the hydraulic cylinder 302 is started, and the piston end of the hydraulic cylinder 302 drives the mounting plate 303 to move downward, and the mounting plate 303 drives the universal wheel 304 to move downward, and the universal wheel 304 contacts the ground, and the bottom of the support seat 203 is separated from the ground, so that the falling film heat exchanger body 100 can be moved conveniently through the universal wheel 304, and the movement is more convenient. After the movement is completed, the universal wheel 304 is driven by the hydraulic cylinder 302 to move upward and separate from the ground, which can improve the stability of the equipment.

[0033] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
