[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0030] like Figure 1-Figure 4 As shown, the synthetic leather water-based treatment agent production waste recycling device provided by the utility model includes a heating kettle 1 for heating the synthetic leather water-based treatment agent for reaction, a reaction tank 2 for storing waste water generated in the production process of the synthetic leather water-based treatment agent, an energy storage tank 3 and a heating and pressurizing device 4; a spiral heating coil 21 is wound around the outer wall of the reaction tank 2; the side wall of the reaction tank 2 is made of metal material, stainless steel is used in this embodiment, of course, other metal materials can also be used, preferably stainless steel.

[0031] The heating coil 21 is arranged in close contact with the outer surface of the side wall of the reaction tank 2, which can achieve a better heat transfer effect. In order to further improve the heat transfer effect, the heating coil is partially embedded in the side wall of the reaction tank to increase the heat transfer area.

[0032] In this embodiment, the energy storage tank 3 is a horizontal energy storage tank, and the heating kettle 1 is a vertical heating kettle.

[0033] The top of the heating kettle 1 is provided with an exhaust port 11, which is connected to one end of the energy storage tank 3 through a first pipe 5, and the other end of the energy storage tank 3 is connected to the air inlet end of the heating and pressurizing device 4 through a second pipe 6. The air outlet end of the heating and pressurizing device 4 is connected to one end of the heating coil 21 through a third pipe 7, and the other end of the heating coil 21 is connected to one end of the energy storage tank 3 through a fourth pipe 8. Among them, the horizontal height of one end of the heating coil is lower than the horizontal height of the other end of the heating coil. The heating and pressurizing device can use an existing product.

[0034] In order to improve the quality of the exhaust gas returning to one end of the energy storage tank 3, a filtering device, such as a filter net, can be set in the fourth pipe. When the mesh is small enough, some particles can be filtered out. Of course, regular cleaning is required to avoid blockage and affect the reflux efficiency.

[0035] The energy storage tank 3 is provided with a discharge port, and a filter 31 is arranged at the discharge port. When the waste gas storage volume in the energy storage tank reaches a critical value, it can be discharged to the outside through the discharge port. However, when discharging, it needs to be processed by the filter and discharged to the outside under the condition that the discharge requirements are met. Among them, the filter can be an existing product. A control valve can be arranged at the discharge port to control the discharge, which is not shown in the attached drawings of this scheme.

[0036] The first pipeline 5 is provided with a first throttle valve 51, the second pipeline 6 is provided with a second throttle valve 61, the third pipeline 7 is provided with a third throttle valve 71, the fourth pipeline 8 is provided with a fourth throttle valve 81, the first throttle valve 51, the second throttle valve 61, the third throttle valve 71 and the fourth throttle valve 81 are electrically connected to the controller respectively. The first pipeline 5 is provided with a first temperature sensor 52, the second pipeline 6 is provided with a second temperature sensor 62, the third pipeline 7 is provided with a third temperature sensor 72, the first temperature sensor 52, the second temperature sensor 62 and the third temperature sensor 72 are electrically connected to the controller respectively.

[0037] The temperature data of the exhaust gas on each pipeline is collected through the above-mentioned temperature sensor and fed back to the controller, which controls the corresponding throttle valve working state, such as opening and closing, after analysis. The temperature sensor and throttle valve can both be existing products. The throttle valve can use a device with adjustable opening and closing degree, which is conducive to more accurate control of the exhaust gas flow. The controller can also be an existing product, which is not shown in the attached figure of this scheme.

[0038] The working principle of the synthetic leather water-based treatment agent production waste recycling device provided by the utility model is: the waste gas with a certain amount of heat volatilized during the heating reaction of the heating kettle is sent to the energy storage tank, and then passes through the heating and pressurizing device to further increase the heat of the waste gas, and then passes through the reaction pool, providing a certain amount of heat to the reaction pool to promote the reaction efficiency during wastewater treatment, and then the waste gas flows back to the energy storage tank for recycling. Since the waste gas itself has a certain amount of heat, when it is necessary to further increase the heat of the waste gas, the energy consumption of the heating and pressurizing device can be effectively reduced, thereby achieving the purpose of energy saving.

[0039] The present invention has been described by the above-mentioned relevant embodiments and drawings, but the above-mentioned embodiments are only examples for implementing the present invention.
