Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steam recovery, in particular to a steam recovery and reuse device. Background Art
[0002] In food and industrial sandwich pots and other equipment, using steam for heating is a common and efficient method. The heating effect of steam is closely related to its temperature and pressure. When there is too much steam in the sandwich pot, it may cause the temperature or pressure in the pot to be too high, thus affecting the cooking quality of food or the processing effect of industrial products. Therefore, discharging excess steam is an important means to control the temperature and pressure in the pot.
[0003] Steam discharge actually releases energy into the environment, which will lead to reduced energy efficiency. If the steam discharge is not effectively utilized or recycled, energy will be wasted. Although steam itself is harmless, if it is discharged into indoor or outdoor environments in large quantities, it may cause increased air humidity and have adverse effects on equipment and the environment. Therefore, the discharged steam needs to be recycled.
[0004] In the prior art, a condenser is usually used to condense steam into water, which is then reused. As steam is continuously introduced, the temperature of the condensing medium in the condenser will continue to rise. When it reaches the critical point, it will affect the subsequent condensation effect of the steam, resulting in the inability to fully condense the steam, thereby causing energy waste. If the condensing medium is to always maintain a low condensation temperature, it needs to be refrigerated. However, refrigeration consumes electrical energy, thereby affecting the overall energy recovery rate. Utility Model Content
[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a steam recovery and reuse device, which solves the problem that when the condenser recovers the exhaust steam, the steam cannot be fully condensed due to the increase in the temperature of the condensing medium, thereby affecting the energy recovery rate.
[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a steam recovery and reuse device is proposed, including an insulated box, a first cylinder and a plurality of evenly distributed second cylinders are installed on the top of the insulated box, heat exchange tubes are installed in the first cylinder and the second cylinder respectively, and a steam recovery tube connected with the internal heat exchange tube is installed at the side wall of the top end of the first cylinder, a steam conduit connected with the internal heat exchange tube is installed at the side wall near the top end of the second cylinder, the end of the steam conduit away from the second cylinder passes through the top of the insulated box, the bottom end of the heat exchange tube is connected with a downpipe connected with the insulated box, water supply and drainage mechanisms are installed on the first cylinder and the second cylinder, and a drain pipe with a valve is installed on the side wall near the bottom end of the insulated box.
[0007] As a further technical solution of the utility model, the water supply and drainage mechanism includes a water supply pipe located above the first cylinder and the second cylinder, a first branch pipe with a valve is installed between the water supply pipe and the first cylinder and the second cylinder, a horizontal pipe arranged along the length direction of the insulation box is installed on the top, and a second branch pipe with a valve is connected to the side walls of the first cylinder and the second cylinder near the bottom end, and the second branch pipe is connected to the horizontal pipe.
[0008] As a further technical solution of the utility model, the valve on the first branch pipe includes a first solenoid valve, the valve on the second branch pipe includes a second solenoid valve, and the first solenoid valve and the second solenoid valve are both electrically connected to a controller, and the controller is installed on the outer wall of the insulation box.
[0009] As a further technical solution of the utility model, the bottoms of the first cylinder and the second cylinder are respectively inlaid with shells that penetrate the top of the insulation box, and the downpipe is installed with a one-way valve located in the shell.
[0010] As a further technical solution of the present utility model, the controller is electrically connected to multiple temperature sensors and multiple liquid level sensors, and the multiple temperature sensors are respectively embedded and installed on the outer cylinder walls of the first cylinder and the second cylinder, and the multiple liquid level sensors are respectively installed on the upper surfaces of the inside of the first cylinder and the second cylinder.
[0011] As a further technical solution of the utility model, a horizontal plate is installed between the inner walls of the insulation box near the top, and the horizontal plate divides the interior of the insulation box into an upper cavity and a lower cavity from top to bottom, and a plurality of strip plates are installed in the upper cavity, and the plurality of strip plates divide the upper cavity into a first cavity and a plurality of second cavities from right to left, and the first cavity and the plurality of second cavities are connected to the lower cavity by an overflow pipe with a U-shaped structure, and an exhaust valve is installed on the top of the first cavity.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. In the utility model, the exhaust steam is conveniently introduced into the heat exchange tube in the first cylinder through the steam recovery pipe, so as to facilitate the heat exchange between the steam and the water in the first cylinder. During the heat exchange process, the steam condenses to form condensed water which enters the heat preservation box through the downpipe. The steam that has not condensed in the first cylinder is conveniently introduced into the heat exchange tube in the second cylinder by using a plurality of steam guide tubes, so as to realize multi-stage condensation of steam, so that the steam can be fully condensed, which is beneficial to improve the recovery rate of the steam heat. The condensed water recovered into the heat preservation box still has a relatively high temperature. The recovered condensed water can be used for steam production, which can effectively reduce the energy consumption.
[0014] 2. In the utility model, the water supply and drainage mechanism not only facilitates the discharge of the heated water in the first cylinder or the second cylinder after the water in the first cylinder or the second cylinder is heated to the set temperature, but also facilitates the timely replenishment of cold water at room temperature into the first cylinder or the second cylinder, which is beneficial to improving the condensation recovery effect of steam. After the first cylinder or the second cylinder discharges the heated water, the heated water can be used to produce steam. Since the heated water has a certain temperature, lower energy will be consumed when producing steam, which is beneficial to further improve the energy utilization rate.

DETAILED DESCRIPTION
[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.
[0020] like Figure 1-3 As shown, a steam recovery and reuse device comprises an insulated box 1, a first cylinder 2 and a plurality of evenly distributed second cylinders 3 are installed on the top of the insulated box 1, heat exchange tubes 4 are installed in the first cylinder 2 and the second cylinder 3 respectively, in order to extend the flow path of the steam in the heat exchange tube 4, in this embodiment, the heat exchange tube 4 is a spiral structure, a steam recovery tube 5 connected to the internal heat exchange tube 4 is installed at the side wall of the top end of the first cylinder 2, a steam conduit 6 connected to the internal heat exchange tube 4 is installed at the side wall of the second cylinder 3 near the top end, and the end of the steam conduit 6 away from the second cylinder 3 passes through the top of the insulated box 1;
[0021] The bottom end of the heat exchange tube 4 is connected to a downpipe 7 connected to the insulation box 1. The bottoms of the first cylinder 2 and the second cylinder 3 are respectively inlaid with a shell 14 that passes through the top of the insulation box 1. The downpipe 7 is installed with a one-way valve 15 located in the shell 14.
[0022] A horizontal plate 18 is installed between the inner walls of the insulation box 1 near the top, and the horizontal plate 18 divides the interior of the insulation box 1 into an upper cavity and a lower cavity from top to bottom, and a plurality of strip plates 19 are installed in the upper cavity, and the plurality of strip plates 19 divide the upper cavity into a first cavity and a plurality of second cavities from right to left, and the first cavity and the plurality of second cavities are connected to the lower cavity by an overflow pipe 20 of a U-shaped structure, so that condensed water can flow into the lower cavity through the overflow pipe 20, and an exhaust valve 21 is installed on the top of the first cavity. In this embodiment, the bottom end of the steam conduit 6 is connected to the second cavity, and the second cavity has a smaller spatial area. After the condensed water falls into it, its spatial area will be smaller, so that the steam entering the second cavity can flow out through the steam conduit 6.
[0023] A water supply and drainage mechanism is installed on the first cylinder 2 and the second cylinder 3, and the water supply and drainage mechanism includes a water supply pipe 9 located above the first cylinder 2 and the second cylinder 3, and a first branch pipe 10 with a valve is installed between the water supply pipe 9 and the first cylinder 2 and the second cylinder 3, so as to facilitate the replenishment of normal temperature cold water into the first cylinder 2 and the second cylinder 3, and a transverse pipe 11 arranged along the length direction is installed on the top of the thermal insulation box 1, and a second branch pipe 12 with a valve is connected to the side wall of the first cylinder 2 and the second cylinder 3 near the bottom end, and the second branch pipe 12 is connected to the transverse pipe 11, so as to facilitate the discharge of the water heated by heat exchange in the first cylinder 2 and the second cylinder 3, and a drain pipe 8 with a valve is installed on the side wall of the thermal insulation box 1 near the bottom end.
[0024] The valve on the first branch pipe 10 includes a first solenoid valve, and the valve on the second branch pipe 12 includes a second solenoid valve, and the first solenoid valve and the second solenoid valve are both electrically connected to a controller 13, and the controller 13 is installed on the outer wall of the thermal insulation box 1, and the controller 13 is electrically connected to multiple temperature sensors 16 and multiple liquid level sensors 17, respectively, and the multiple temperature sensors 16 are respectively embedded and installed on the outer walls of the first cylinder 2 and the second cylinder 3, and the multiple liquid level sensors 17 are respectively installed on the upper surfaces inside the first cylinder 2 and the second cylinder 3.
[0025] The working principle of the utility model is as follows: the steam discharged from the sandwich pot is introduced into the heat exchange tube 4 in the first cylinder 2 by using the steam recovery pipe, so that the steam exchanges heat with the cold water in the first cylinder 2 and condenses, and the condensed water enters the upper cavity through the downpipe 7. As the condensed water level rises, the condensed water finally flows into the lower cavity through the overflow pipe 20. The steam that has not condensed in the first cylinder 2 will enter the heat exchange tube 4 in the second cylinder 3 along the steam conduit 6. The steam can be fully condensed and recovered by using multiple second cylinders 3, and the temperature sensor 16 can be used to monitor the temperature of the first cylinder 2 or the second cylinder 3. When the water temperature rises to the threshold value, the controller 13 controls the second solenoid valve on the corresponding second branch pipe 12 to open, and discharges the heated water for subsequent steam production. The liquid level sensor 17 monitors the liquid level in the first cylinder 2 or the second cylinder 3. When the liquid level drops to the minimum value, the controller 13 controls the first solenoid valve on the corresponding first branch pipe 10 to open, and cooperates with the water supply pipe 9 to add normal temperature cold water to the first cylinder 2 or the second cylinder 3, so that there is always cold water at a lower temperature in the first cylinder 2 or the second cylinder 3, which is convenient for fully condensing the steam.
[0026] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
