Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a tubular heat exchanger used for SCR treatment of stainless steel pickling waste gas. Background Art

[0002] A tubular heat exchanger is a device that uses the heat pipe principle for heat exchange. It is mainly composed of a group of packaged heat pipes. The tubular heat exchanger can recover heat from the stainless steel pickling waste gas and use it to heat water to generate more electricity. The tubular heat exchanger can be widely used in engine-driven generator sets to improve the efficiency of exhaust gas.

[0003] The existing tubular heat exchangers are large and heavy, making them inconvenient to transfer quickly and stably.

[0004] The reason for this problem is that, due to the wide flow cross-section of the tubular heat exchanger, it carries a large amount of water inside, and the overall volume is large and heavy. In addition, the current tubular heat exchanger is mainly fixed to the ground by a support frame. When transferring the tubular heat exchanger, it is necessary to dismantle the support frame and then use equipment or manpower to move it. During the transfer, the water inside it will shake, resulting in poor stability during transfer and an inconvenient transfer process. In view of the shortcomings of the existing technology, we propose a tubular heat exchanger for SCR treatment of stainless steel pickling waste gas to solve the above problems. Utility Model Content

[0026] The embodiment of the present application provides a tubular heat exchanger for SCR treatment of stainless steel pickling waste gas, thereby solving the problem that the current tubular heat exchanger is large and heavy and not convenient for rapid and stable transfer.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a tubular heat exchanger for SCR treatment of stainless steel pickling waste gas.

[0029] According to the attached Figure 1-5 As shown, a tubular heat exchanger for SCR treatment of stainless steel pickling waste gas comprises:

[0030] The heat exchanger unit includes a heat exchanger body 1 and a medium inlet 101 and a medium outlet 102 arranged on the upper and lower sides of the heat exchanger body 1. The heat exchanger unit can be referenced by the model of kx-130-1.2;

[0033] The moving unit includes a pulley 6 arranged at the bottom of the supporting plate 2 for transferring the supporting plate 2 and a slider 5 for fixing the trapezoidal plate 3 .

[0034] The side wall of the trapezoidal plate 3 is provided with a side opening 201 , and a screw rod 4 is threaded through the top of the side opening 201 . The bottom of the screw rod 4 is rotatably connected to the top of the trapezoidal plate 3 , and the trapezoidal plate 3 can be driven to move up and down by rotating the screw rod 4 .

[0035] A trapezoidal groove 202 is formed at the bottom of the support plate 2 , and the trapezoidal plate 3 is installed inside the trapezoidal groove 202 .

[0036] Multiple groups of slide grooves 301 are provided on both sides of the trapezoidal plate 3. A clamping block 203 is fixedly connected inside the trapezoidal groove 202. The clamping block 203 is slidably connected inside the slide groove 301.

[0039] A spring 501 is fixedly connected between the slider 5 and the concave opening 204 , and the spring 501 is used to reset the slider 5 .

[0040] When the utility model is in use, the heat exchanger body 1 is first moved to a desired location by the pulley 6, and then the screw 4 on the trapezoidal plate 3 is rotated, the screw 4 will push the trapezoidal plate 3 to move downward until the square opening 302 on the trapezoidal plate 3 corresponds to the slider 5, at which time the slider 5 will be plugged into the inside of the square opening 302 by the elastic force of the spring 501, and the trapezoidal plate 3 is fixed. The heat exchanger body 1 can be stably placed by the trapezoidal plate 3, and the medium inlet 101 on the top of the heat exchanger body 1 will recover heat from the stainless steel pickling waste gas, and use it to heat water, and then cool it through the cold water system, which can generate more electrical energy and improve the utilization rate of the waste gas.

[0041] In summary, compared with the prior art, the present invention has the following beneficial effects: by arranging a pulley 6 on the support plate 2 at the bottom of the heat exchanger main body 1, the heat exchanger main body 1 can be quickly transferred, avoiding the current situation where the heat exchanger main body 1 is large and heavy and cannot be conveniently transferred; by arranging a slider 5 and a trapezoidal plate 3 at the bottom of the support plate 2, the trapezoidal plate 3 can be moved by rotating the screw 4 at the top of the trapezoidal plate 3.
