Description

Technical Field

[0001] The utility model relates to a waste heat utilization technology, in particular to a technology for recycling condensed water in an interlayer of a reaction tank. Background Art

[0002] Chemical condensate waste heat recovery refers to the process of recovering the waste heat contained in the waste gas condensate through appropriate technical means during the chemical production process. In chemical production, waste gas condensate contains not only water but also a large amount of heat energy. If this heat energy can be effectively recycled, it will help improve energy efficiency, reduce energy consumption and reduce production costs.

[0003] In many chemical plants, chemical reactors are widely used chemical equipment. Chemical reactors usually have a heating layer, which is usually heated by electric heating oil. Although this heating method is convenient, it consumes a lot of energy. Especially in cold areas, the heating of numerous chemical reactors consumes a lot of electricity. If the waste heat of the recovered condensed water can be recycled, energy saving can be achieved. Utility Model Content

[0004] The main purpose of the utility model is to provide a technology for realizing the utilization of waste heat of condensed water in the heating layer of a reaction tank.

[0008] The beneficial effect of the above scheme is: the condensed water of the chemical reaction is collected uniformly and then transferred to the outer interlayer in the reaction tank, and circulated continuously so that the reaction tank forms preliminary waste heat or insulation effect. In this way, when the inner interlayer is heated electrically, the energy required will be significantly reduced.

[0009] Preferably, there are delivery pipes on the upstream and downstream sides of the delivery pump, respectively. The delivery pipe on the upstream side is connected to the lower end of the condensate recovery tank, and the delivery pipe on the downstream side is connected to the inlet of the waste heat utilization circulation pipe in the outer interlayer.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] Embodiment 1:

[0020] like Figures 1 to 3 As shown, the utility model provides a device for recovering waste heat of steam condensate from chemical equipment, which includes a condensate recovery tank 10, a waste heat transmission component 20 and a waste heat utilization unit 30;

[0021] The waste heat transfer assembly 20 has a delivery pipe 21 and a delivery pump 22;

[0022] The waste heat utilization unit 30 has a chemical reaction tank 31, the tank wall of the chemical reaction tank 30 has an outer interlayer 33 and an inner interlayer 32, the outer interlayer 33 has a waste heat utilization circulation pipe 35, and the inner interlayer 32 has an electric heating oil pipe 36; the waste hot water in the condensate recovery pool 10 is transferred to the waste heat utilization circulation pipe 35 of the outer interlayer 33 through the waste heat transfer component 20 for utilization, so as to realize preheating or heat preservation of the chemical reaction tank 31. The water in the circulation pipe 35 can be circulated back to the condensate recovery pool 10 or flow into other recovery containers.

[0023] The condensed water from the chemical reaction is collected uniformly and then transferred to the outer interlayer 33 in the reaction tank. This continuous circulation allows the reaction tank 31 to form a preliminary waste heat or insulation effect. In this way, when the inner interlayer 32 is electrically heated, the energy required to be consumed will be significantly reduced.

[0024] Embodiment 2:

[0025] Preferably, the delivery pump 22 in this embodiment has a delivery pipe 21 on the upstream and downstream sides respectively, the delivery pipe on the upstream side is connected to the lower end of the condensate recovery tank 10, and the delivery pipe on the downstream side is connected to the inlet of the waste heat utilization circulation pipe 35 in the outer interlayer 33.

[0026] Preferably, the condensate recovery tank 10 has a main body heat-insulating container.

[0027] Combination Figure 4 As shown, preferably, the middle part of the main heat-insulating container has an adaptive inlet assembly 40, and the adaptive inlet assembly 40 includes an inlet pipe 41, a left movable block 42 and a right movable block 43. The inlet pipe 41 is connected to the interior of the main heat-insulating container, and the left movable block 42 and the right movable block 43 are movably arranged on the left and right sides above the inlet pipe 41, respectively. The left movable block 42 is connected to the left fixed plate 45 through the left return spring 44, and the right movable block 43 is connected to the right fixed plate 47 through the right return spring 46.

[0028] When it is necessary to recycle the condensed water formed by the chemical reaction, it is usually sufficient to connect the recovery pipe 50 to the position of the inlet pipe 41. However, it is found in practice that the connection method is relatively cumbersome, especially when it is necessary to frequently change the recovery pipe 50 at different positions to connect with the inlet pipe 41. If the recovery pipe 50 is simply inserted into the position of the inlet pipe 41, the connection position is also unstable. In this regard, by setting the clamping structure on the left and right sides, that is, the left moving block 42 and the right moving block 43, the automatic clamping and fixing effect of the middle recovery pipe 50 is realized, and it is also convenient to adjust the insertion depth of the recovery pipe 50 in the inlet pipe 41, which is very convenient to use.

[0029] A guide track 48 is provided on the top wall of the main heat-insulating container, and the bottoms of the left moving block 41 and the right moving block 42 cooperate with the guide track 48 via a guide slider 49 .

[0030] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
