Abstract
Description
Technical Field
[0001] This utility model relates to the field of condensate recovery technology, specifically a steam condensate recovery device. Background Technology
[0002] In some industrial production processes, high-temperature steam is required to produce related products. Therefore, steam is widely used as a heat energy carrier in industries such as petroleum and chemical engineering.
[0003] In the prior art, Chinese utility model application number CN202221441608.4 discloses a steam condensate recovery and utilization device. One end of the conduit is connected to the cooking pot, and the other end is connected to the heating tank, so that the steam condensate in the cooking pot is transported to the heating tank through the conduit. By setting up auxiliary recovery components, the amount of condensate collected is increased. The combination of the above components can effectively solve the problem that the steam condensate in the cooking pot is not centrally recovered and utilized and is directly discharged, which will cause a lot of energy waste.
[0004] Although this technical solution can achieve a certain degree of condensate recovery, the efficiency of condensate generation is low due to the high temperature of steam, and the waste heat of steam is not utilized in the process of generating condensate, which reduces the utilization effect of steam. Therefore, we need to propose a steam condensate recovery device. Utility Model Content
[0005] The purpose of this utility model is to provide a steam condensate recovery device. By setting an external condensate recovery device, the waste heat of steam can be utilized while accelerating the vapor-liquid conversion efficiency of high-temperature steam, thereby improving the condensate recovery efficiency and the utilization rate of steam, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steam condensate recovery device, comprising:
[0007] A condensate recovery tank and a steam diversion assembly installed on top of the condensate recovery tank for steam to enter, thereby guiding the flow of steam;
[0008] A steam guiding component and multiple sets of condensate diversion buckets are installed inside the condensate recovery tank to guide the flow direction of steam. A cold water heat exchange component that absorbs heat from the steam is set between the steam guiding component and the multiple sets of condensate diversion buckets. A steam circulation channel for steam flow is formed between the steam guiding component and the multiple sets of condensate diversion buckets, so that the cold water absorbs the heat from the steam and then quickly condenses into condensate on the cold water heat exchange component.
[0009] Preferably, the steam guiding assembly includes a column and multiple sets of steam guiding hoods. The multiple sets of steam guiding hoods are fixed to the outside of the column from top to bottom, and the diameter of the multiple sets of steam guiding hoods decreases from top to bottom. All sets of steam guiding hoods are conical hoods. The multiple sets of condensate diversion hoppers are arranged alternately with the multiple sets of steam guiding hoods, and the multiple sets of condensate diversion hoppers are annular funnels.
[0010] Preferably, the cold water heat exchange assembly includes a first water guide, a heat exchange tube, and a second water guide. The heat exchange tube is disposed between the first and second water guides. The first water guide is disposed at the bottom of the condensate recovery tank, and the second water guide is disposed at the top of the condensate recovery tank.
[0011] Preferably, the first water guide includes a bottom ring pipe, and a cold water inlet pipe that penetrates the condensate recovery tank is connected to the bottom ring pipe;
[0012] The second water guide includes a top ring pipe, on which a hot water outlet pipe penetrating the condensate recovery tank is connected, and the diameter of the top ring pipe is larger than the diameter of the bottom ring pipe.
[0013] Preferably, the heat exchange tubes are mainly composed of multiple sets of heat absorption tubes that connect the top ring tube and the bottom ring tube. The multiple sets of heat absorption tubes are arranged in a circular array, and each set of heat absorption tubes has multiple sets of heat exchange fins on its outer side.

[0015] Preferably, the steam diversion assembly includes a connecting cover, with a steam inlet pipe at the upper end of the connecting cover and multiple sets of steam diversion pipes connected to the condensate recovery tank at the lower end of the connecting cover.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention mainly utilizes the cooperation between a cold water heat exchange component, a steam guiding component, a condensate drainage hopper, and a steam circulation channel. The cold water heat exchange component fully contacts the steam in the steam circulation channel, efficiently absorbing steam heat. The conical steam drainage hood of the steam guiding component guides the steam to meandering flow, extending the residence time of the steam in the steam circulation channel, allowing the steam to fully condense on the surface of the cold water heat exchange component. This improves the steam heat recovery efficiency, accelerates the condensate generation rate, reduces energy consumption, and enhances practicality. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a steam condensate recovery device, comprising:
[0025] The condensate recovery tank 1 and the steam diversion assembly 2 installed on the top of the condensate recovery tank 1 for steam to enter guide the flow of steam.
[0026] A steam guiding component 5 and multiple sets of condensate diverting hoppers 6 are installed inside the condensate recovery tank 1 to guide the flow direction of steam. A cold water heat exchange component 4 that absorbs heat from the steam is installed between the steam guiding component 5 and the multiple sets of condensate diverting hoppers 6. A steam circulation channel 7 for steam flow is formed between the steam guiding component 5 and the multiple sets of condensate diverting hoppers 6. After the cold water absorbs the heat from the steam, it quickly condenses into condensate on the cold water heat exchange component 4. The condensate diverting hoppers 6 can guide and collect the condensed condensate, prevent secondary evaporation of condensate, improve condensate recovery efficiency, and realize efficient recovery of steam heat and effective collection of condensate.
[0027] The steam guiding assembly 5 includes a column 51 and multiple sets of steam guiding hoods 52. The multiple sets of steam guiding hoods 52 are fixed to the outside of the column 51 from top to bottom, and the diameter of the multiple sets of steam guiding hoods 52 decreases from top to bottom. All of the multiple sets of steam guiding hoods 52 are conical hoods. Multiple sets of condensate diversion hoppers 6 are alternately arranged with the multiple sets of steam guiding hoods 52, and the multiple sets of condensate diversion hoppers 6 are annular funnels. The steam guiding assembly 5 makes the steam flow in a tortuous manner, prolonging the contact time between the steam and the cold water heat exchange assembly 4. Combined with the increased contact area of the heat exchange fins 422, it significantly improves the absorption efficiency of cold water on steam heat and accelerates the steam condensation rate.
[0028] The cold water heat exchange assembly 4 includes a first water guide 41, a heat exchange tube 42, and a second water guide 43. The heat exchange tube 42 is disposed between the first water guide 41 and the second water guide 43. The first water guide 41 is disposed at the bottom of the condensate recovery tank 1, and the second water guide 43 is disposed at the top of the condensate recovery tank 1.
[0029] The first water guide 41 includes a bottom ring pipe 411, and a cold water inlet pipe 412 that penetrates the condensate recovery tank 1 is connected to the bottom ring pipe 411, so that cold water can enter the condensate recovery tank 1 and be preheated by the condensate accumulating at the bottom of the condensate recovery tank 1.
[0030] The second water guide component 43 includes a top ring pipe 431, on which a hot water outlet pipe 432 that penetrates the condensate recovery tank 1 is connected. The diameter of the top ring pipe 431 is larger than that of the bottom ring pipe 411. After the cold water and steam exchange heat through the heat exchange pipe component 42, the water is heated and discharged through the hot water outlet pipe 432, thereby improving the energy utilization rate.
[0031] The heat exchange tube 42 is mainly composed of multiple sets of heat absorption tubes 421 that connect the top ring tube 431 and the bottom ring tube 411. The multiple sets of heat absorption tubes 421 are arranged in a circular array, and each set of heat absorption tubes 421 has multiple sets of heat exchange fins 422 on its outer side. The circular array of heat absorption tubes 421, together with the heat exchange fins 422, maximizes the contact area between cold water and steam, improves heat exchange efficiency, effectively utilizes steam heat, improves energy utilization, and simultaneously heats the cold water.
[0032] The condensate recovery tank 1 has a conical cross-section. The bottom of the condensate recovery tank 1 is equipped with a condensate drain pipe 8 for condensate discharge. The bottom of the condensate recovery tank 1 is fixedly connected to a support base 3. The conical design facilitates the rapid collection of condensate to the bottom of the tank for discharge, avoids condensate residue in the tank, and improves condensate discharge efficiency.
[0033] The steam diversion assembly 2 includes a connecting cover 22. A steam inlet pipe 21 is provided at the upper end of the connecting cover 22, and multiple sets of steam diversion pipes 23 connected to the condensate recovery tank 1 are provided at the lower end of the connecting cover 22. The steam diversion assembly 2 realizes the planning and diversion of the path of steam entering the condensate recovery tank 1, guides the steam to enter the space of the condensate recovery tank 1 evenly, and disperses the steam to avoid the steam concentrating and impacting the interior of the condensate recovery tank 1. This allows the steam to be distributed more evenly in the condensate recovery tank 1, creating good conditions for subsequent heat exchange and condensation between steam and cold water, and improving the steam utilization efficiency and the uniformity of the condensation effect.
[0034] In use, steam enters the connecting hood 22 through the steam inlet pipe 21 of the steam diversion assembly 2, and is dispersed into the condensate recovery tank 1 through multiple sets of steam diversion pipes 23. Inside the tank, multiple sets of conical steam guide hoods 52 and multiple sets of condensate guide buckets 6 of the steam guide assembly 5 guide the steam to flow in a tortuous manner along the steam circulation channel 7, extending its residence time in the tank. At the same time, cold water enters the bottom ring pipe 411 of the first water guide component 41 through the cold water inlet pipe 412, and after absorbing the heat of the steam through multiple sets of heat absorption pipes 421 with heat exchange fins 422, it becomes hot water and is discharged from the hot water outlet pipe 432 of the top ring pipe 431 of the second water guide component 43. During this process, the steam condenses into water droplets quickly on the surface of the cold water heat exchange assembly 4, and falls onto the steam guide hood 52 and condensate guide buckets 6 under the action of gravity, and is concentrated at the bottom of the condensate recovery tank 1, flowing out through the condensate discharge pipe 8, thus achieving efficient recovery of steam condensate.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
