Description

A leak-proof wastewater evaporator Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment, specifically a wastewater evaporator that is not prone to leakage. Background Technology

[0002] Industrial wastewater evaporators are core equipment for treating high-concentration organic wastewater and saline wastewater. They concentrate pollutants by heating and evaporating the water in the wastewater. However, traditional evaporators have the following potential leakage risks:

[0003] Existing industrial wastewater evaporators have a simple tank structure, which is a single-layer structure. The wastewater has a complex composition (such as strong acids, strong alkalis, and chloride ions), and long-term operation can easily lead to perforation and leakage of the equipment body. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a wastewater evaporator that is not prone to leakage.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wastewater evaporator that is not prone to leakage, comprising an evaporator base, an outer tank at the upper end of the evaporator base, an inner tank inside the outer tank, and a sandwich layer between the inner tank and the outer tank;

[0008] The outer tank is provided with a top cover at the top end, and an exhaust pipe is provided in the middle part of the top cover. The top of the outer tank is provided with a feed pipe that penetrates the inner tank, and the bottom of the outer tank is provided with a discharge pipe that is inserted into the interlayer. The discharge pipe is provided with a valve.

[0009] The outer tank is provided with a ring frame around its perimeter, and a control line is provided inside the ring frame. A control device is provided on one side of the ring frame, and a warning light is provided on the control device. Multiple air pressure sensors located inside the interlayer are provided on the inner side of the ring frame, and the multiple air pressure sensors are connected to the control device by electrical signals.

[0010] To facilitate the installation of the inner can inside the outer can, the present invention includes an improvement in which the inner can is provided with a plurality of positioning blocks that connect the outer wall of the inner can and the inner wall of the outer can, and the positioning blocks are provided with cavities.

[0011] To facilitate assembly of the top cover on the top of the outer can, the present invention is improved by fixing the top cover to the upper end of the outer can with bolts.

[0012] Further improvements to this invention include: the inner tank is made of corrosion-resistant stainless steel; the cross-sectional width of the interlayer is 50-100mm; and the interlayer is filled with low-pressure inert gas.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a wastewater evaporator that is not prone to leakage, and has the following beneficial effects:

[0015] Enhanced leak prevention: Compared with traditional single-layer evaporators, this evaporator adopts a design in which the inner tank and the outer tank form a sandwich structure. The sandwich structure is filled with low-pressure inert gas. Even if the inner tank is perforated due to long-term contact with complex wastewater components, the wastewater will first enter the sandwich structure. The buffer layer formed by the inert gas can delay leakage, and the pressure sensor can detect abnormalities in time, which greatly reduces the risk of direct leakage of wastewater.

[0016] Improved monitoring and early warning timeliness: Multiple pressure sensors are distributed within the interlayer, enabling comprehensive and real-time monitoring of the interlayer pressure. Once an abnormal pressure occurs, the control equipment can quickly trigger an alarm light, allowing operators to promptly detect potential leaks and prevent environmental pollution and production accidents caused by leaks, thereby improving the safety and reliability of equipment operation.

[0021] 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.

[0022] Please refer to Figures 1-3. The present invention provides a leak-proof wastewater evaporator, which includes an evaporator base 1, an outer tank 2 at the upper end of the evaporator base 1, an inner tank 13 inside the outer tank 2, and a sandwich layer between the inner tank 13 and the outer tank 2.

[0023] The outer tank 2 is provided with a top cover 3 at the upper end, and an exhaust pipe 4 is provided in the middle part of the top cover 3. The top of the outer tank 2 is provided with a feed pipe 5 that penetrates the inner tank 13. The bottom of the outer tank 2 is provided with a discharge pipe 6 that is inserted into the interlayer, and a valve 7 is provided on the discharge pipe 6.

[0024] The outer tank 2 is provided with a ring frame 8 around its periphery. The ring frame 8 is provided with a control line. A control device 9 is provided on one side of the ring frame 8. The control device 9 is provided with a warning light 10. Multiple air pressure sensors 11 located inside the interlayer are provided on the inner side of the ring frame 8. The multiple air pressure sensors 11 are connected to the control device 9 by electrical signals.

[0025] The top cover 3 is fixed to the upper end of the outer tank 2 by bolts.

[0026] During the operation of this leak-proof wastewater evaporator, wastewater enters the inner tank 13 through the feed pipe 5 at the top of the outer tank 2.

[0027] The inner tank 13 is made of corrosion-resistant stainless steel.

[0028] The inner tank 13 is made of corrosion-resistant stainless steel, which can effectively resist the erosion of complex components in wastewater (such as strong acids, strong alkalis, and chloride ions), providing a stable space for wastewater evaporation. When the evaporator is working, the wastewater in the inner tank 13 is evaporated by heating, and the steam is discharged through the exhaust pipe 4 in the middle of the top cover 3, thus achieving wastewater concentration treatment.

[0029] The cross-sectional width of the interlayer is 50-100mm, and the interlayer is filled with low-pressure inert gas.

[0030] The interlayer between the inner tank 13 and the outer tank 2 is filled with low-pressure inert gas to form a buffer isolation layer.

[0031] The inner tank 13 is provided with a plurality of positioning blocks 12 that connect the outer wall of the inner tank 13 and the inner wall of the outer tank 2, and the positioning blocks 12 are provided with cavities.

[0032] The multiple positioning blocks 12 connecting the outer wall of the inner tank 13 and the inner wall of the outer tank 2 not only facilitate the installation and fixation of the inner tank 13 in the outer tank 2, but also enhance the structural stability to a certain extent through their internal cavities, while also playing a certain role in guiding and distributing the inert gas in the interlayer.

[0033] Multiple pressure sensors 11 located inside the interlayer of the ring frame 8 monitor the air pressure within the interlayer in real time. When the inner tank 13 experiences a perforation and leak, wastewater enters the interlayer, causing a change in air pressure. The pressure sensors 11 promptly detect this change and transmit the signal to the control device 9 via the control line. Upon receiving the abnormal signal, the control device 9 triggers the warning light 10 to illuminate, alerting the operator to a potential leak in the inner tank 13, allowing for timely intervention.

[0034] The inner tank 13 is made of corrosion-resistant stainless steel, which effectively resists the erosion of corrosive substances in wastewater, reduces the possibility of equipment perforation and leakage due to corrosion, extends the overall service life of the evaporator, and reduces equipment maintenance and replacement costs.
