[0001] This utility model relates to the field of coal chemical industry, and in particular to a waste steam water recovery device. Background Technology

[0002] In chemical production processes, some low-energy, small-volume waste steam and hot water are vented or discharged due to their low recovery value, including venting from demineralized water deaerators and boiler feedwater. Since this waste steam and water are dispersed across various workstations and have potential for recovery, directly venting or discharging these resources would result in waste. Therefore, this solution proposes a waste steam and water recovery device to address the aforementioned problem. Utility Model Content

[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] Example 1: This utility model provides the following... Figure 1 The waste steam water recovery device shown includes:

[0025] Waste steam recovery unit 1, with a soft water inlet 101 at the top of one side and a waste steam inlet 102 at the bottom of one side.

[0026] The recovery water tank 2 is connected to the discharge end of the waste steam recovery unit 1. The recovery water tank 2 is used to collect the hot soft water discharged from the waste steam recovery unit 1. A first connecting pipe 5 is provided between the discharge end of the waste steam recovery unit 1 and the inlet end of the recovery water tank 2.

[0027] It should be noted that the waste steam recovery unit 1 is a device for recovering and reusing waste steam (low temperature and low pressure steam) generated in industrial production processes. The waste steam is generated when steam-driven equipment, boilers or other thermal energy equipment are working. Due to its low temperature and pressure, direct discharge would result in energy waste.

[0028] In this design, the waste steam recovery unit 1 collects waste steam from the equipment or process through the waste steam inlet 102. The waste steam is condensed or compressed in the waste steam recovery unit 1 to convert it into water or high-pressure steam. At the same time, soft water is introduced into the waste steam recovery unit 1 through the soft water inlet 101. After exchanging heat with the waste steam, the waste steam cools down and condenses into water, which is then mixed with the soft water. Meanwhile, the heat energy of the waste steam raises the temperature of the soft water, forming hot soft water. The hot soft water is then transported to the recovery water tank 2 through the first connecting pipe 5.

[0029] Specifically, a level gauge 201 is installed in the recycling tank 2, which is used to measure the liquid level in the recycling tank 2.

[0030] It should be noted that the liquid level in the recovery tank 2 is monitored in real time by the liquid level gauge 201 to facilitate the discharge control of the hot soft water collected in the recovery tank 2.

[0031] The external discharge mechanism is located at the drain end of the recycling tank 2 and is used to transport the hot soft water in the recycling tank 2 to the user's work station.

[0032] Specifically, the external discharge agencies include:

[0033] The recovery water pump 3 has a second connecting pipe 6 at its inlet end, and the end of the second connecting pipe 6 away from the recovery water pump 3 is connected to the outlet end of the recovery water tank 2.

[0034] A flow control valve 4 is provided, and a third connecting pipe 7 is provided between one end of the flow control valve 4 and the discharge end of the recovery water pump 3.

[0035] It should be noted that the opening and closing control of the flow control valve 4 is related to the detection data of the level gauge 201. The cooperation between the two can control the changes in the liquid level in the recovery tank 2 to ensure the controlled supply of hot soft water.

[0036] Example 2: This utility model provides the following... Figure 2 and Figure 3 The insulation mechanism shown is applied to a waste steam water recovery device in Embodiment 1. The insulation mechanism is set at the external discharge mechanism and is used for insulation during hot soft water transportation. The insulation mechanism is set on the outer wall of the third connecting pipe 7.

[0037] Specifically, the insulation mechanism includes insulation cotton 8, which is wrapped around the outer wall of the third connecting pipe 7. The two ends of the insulation cotton 8 are respectively provided with a magic male face 801 and a magic female face 802, and the magic male face 801 and the magic female face 802 are bonded together.

[0038] It should be noted that, during the hot soft water transportation process, in order to prevent the temperature inside the hot soft water from exchanging with the outside air during transportation, in this solution, insulation cotton 8 is wrapped around the outer wall of the third connecting pipe 7 to provide insulation and protection for the hot soft water transportation. At the same time, for the connection between Fang Baini insulation cotton 8 and the third connecting pipe 7, both ends of insulation cotton 8 are respectively set with magic male face 801 and magic female face 802. After the insulation cotton 8 is wrapped around the outer wall of the third connecting pipe 7, the insulation cotton 8 is connected by the adhesion between the magic male face 801 and the magic female face 802.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
