Description
Technical Field
[0001] This utility model relates to the field of high-salt wastewater evaporation technology, specifically a four-effect evaporation system for treating high-salt wastewater. Background Technology
[0002] The high-salt wastewater quadruple-effect evaporation system is a highly efficient wastewater treatment device, consisting of four evaporators connected in series. It uses the principle of heating and evaporation to evaporate and concentrate non-volatile solvents, thereby increasing the concentration of solutes.
[0003] For example, the Chinese authorized patent with announcement number CN214990381U (A Novel Triple-Effect Evaporation System for Strongly Acidic and High-Salinity Wastewater) includes a first-effect heating chamber, a first-effect evaporation chamber, a second-effect heating chamber, a third-effect heating chamber, a steam-water separator, a condenser, and a heat source unit. One side of the first-effect heating chamber is connected to and installed with a first-effect evaporation chamber via a pipe; one side of the first-effect evaporation chamber is connected to and installed with a second-effect heating chamber via a pipe; and one side of the second-effect heating chamber is connected to and installed with a second-effect evaporation chamber via a pipe. This novel triple-effect evaporation system for strongly acidic and high-saltity wastewater, by replacing the traditional steam heat source with an electromagnetic heater, achieves a rapid and uniform heating rate, effectively improving heating efficiency and heat exchange performance. Simultaneously, the heat source unit provides excellent heat dissipation and stable support, effectively improving the equipment's heat dissipation and anti-collision function, thus extending the equipment's service life.
[0004] However, most existing high-salinity wastewater quadruple-effect evaporation systems use threaded connections for pipe connections. Over time, these pipes are prone to damage and require internal cleaning. Furthermore, the sealing structure is simple, which can lead to leaks over time. Replacement is time-consuming, labor-intensive, and lacks flexibility. Therefore, these systems do not meet current needs. To address this, we propose a quadruple-effect evaporation system for treating high-salinity wastewater. Utility Model Content
[0005] The purpose of this utility model is to provide a four-effect evaporation system for treating high-salt wastewater, in order to solve the problems mentioned in the background art. Most of the existing four-effect evaporation systems for high-salt wastewater are connected by threaded connections. After long-term use, the pipes are prone to damage and require internal cleaning. In addition, the sealing structure is simple, which can easily lead to leakage over time. Replacement is time-consuming, labor-intensive, and lacks flexibility.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a four-effect evaporation system for treating high-salinity wastewater, comprising: a first-effect evaporation component, a second-effect evaporation component disposed on one side of the first-effect evaporation component, a third-effect evaporation component disposed on one side of the second-effect evaporation component, and a fourth-effect evaporation component disposed on one side of the third-effect evaporation component. Each of the first-effect, second-effect, third-effect, and fourth-effect evaporation components includes a heating tank and an evaporation tank. The heating tank and the evaporation tank are connected to each other via pipes, and each end of the pipe is provided with a connecting component.
[0007] Preferably, the connecting assembly includes a pipe seat and a mounting seat, with a sealing gasket disposed between the pipe seat and the mounting seat, and the sealing gasket is fixed by compression between the pipe seat and the mounting seat.
[0008] Preferably, one side surface of the mounting base is provided with a tank groove, and both ends of the side surface of the mounting base having the tank groove are provided with fixing plates, and both ends of the fixing plates are provided with threaded fasteners.
[0009] Preferably, a connecting groove is provided at the center of the mounting base, and the connecting groove extends through the mounting base. A stable socket is heat-fused to one side surface of the pipe base, and the stable socket is inserted into the connecting groove. A sealing ring is provided on the inner wall of the connecting groove, and the stable socket is tightly connected to the connecting groove through the sealing ring.
[0010] Preferably, the sealing gasket has a through groove at its center, and the stabilizing socket passes through the through groove, with the sealing gasket covering the outside of the stabilizing socket.
[0011] Preferably, a second limiting groove is provided on one side surface of the pipe seat, a first limiting groove is provided on the outside of the connecting groove, a second limiting plate is provided on one side surface of the sealing gasket, a first limiting plate is provided on the other side of the sealing gasket, and the first limiting plate and the second limiting plate are respectively inserted into the first limiting groove and the second limiting groove.
[0012] Preferably, each corner of the pipe seat is provided with a fixing bolt, and the pipe seat is threadedly connected to the mounting seat through the fixing bolt, and the end surface of the pipe is heat-fused to the pipe seat.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model sets connecting components on both sides of the pipe. When installing the connecting components, the stable socket passes through the through groove and is inserted into the connecting groove. It is tightly connected to the connecting groove by the sealing ring, which improves the stability of the connection between the pipe seat and the mounting seat and makes it less prone to force displacement and damage. At this time, the sealing gasket is placed on the outside of the stable socket. Then, the pipe seat and the mounting seat are squeezed to squeeze and fix the sealing gasket. The pipe seat and the mounting seat are fixed by the fixing bolt. The sealing gasket improves the sealing performance of the connection between the pipe seat and the mounting seat. When the pipe is damaged and needs to be repaired, the pipe can be replaced simply by disassembling the pipe seat, which improves the convenience and flexibility of replacement. It solves the problem that most of the pipe connections in the existing high-salt wastewater four-effect evaporation system are connected by threaded connection. After long-term use, the pipe is prone to damage and requires internal cleaning. Moreover, the sealing structure is simple and leakage is prone to occur over time. Replacement is time-consuming and laborious and lacks flexibility.
[0015] (2) By setting a first limiting plate and a second limiting plate on both sides of the sealing gasket, when the pipe seat and the mounting seat squeeze the sealing gasket, the first limiting plate and the second limiting plate are inserted into the first limiting groove and the second limiting groove respectively, which has a limiting effect on the sealing gasket, increases the contact area, improves the connection stability and sealing effect, and avoids water and air leakage.
