Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater discharge technology, specifically a modular evaporation device for industrial wastewater discharge. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus fully utilizing water resources. Wastewater is mainly divided into industrial wastewater and domestic wastewater. Currently, industrial production processes generate a large amount of saline industrial wastewater, and the treatment of this saline industrial wastewater is a necessary step under the current environmental protection situation.

[0003] For example, the authorization announcement number "CN211419641U" is for an evaporation device for industrial wastewater. The temperature sensor monitors the temperature inside the evaporation tank, and the microcontroller reduces the heating power and automatically controls the power output, thus saving energy. In existing evaporation devices for industrial wastewater, the evaporation equipment is a whole unit, and its evaporation components, exhaust components, and heating components are directly fixed in the wastewater treatment evaporation equipment and cannot be quickly separated from the evaporation tank storing industrial wastewater. Therefore, in actual use, the industrial wastewater tank can only be used for evaporation treatment, and its applicability is relatively small.

[0004] Existing evaporation equipment for industrial wastewater uses large ceramic heating tubes that are directly buried at the bottom of the evaporator. Because industrial wastewater contains many impurities and corrosive substances and has extremely complex chemical properties, the ceramic heating tubes are exposed to the highly corrosive and chemically reactive environment of industrial wastewater for extended periods, causing them to age and rust faster. As a result, the heating tubes require frequent repair and maintenance, which is detrimental to reducing the operating costs of evaporation equipment for industrial wastewater. Utility Model Content

[0005] The purpose of this invention is to address the problems in existing industrial wastewater evaporation equipment where the evaporation components, exhaust components, and heating components are directly fixed within the wastewater treatment evaporation equipment and cannot be quickly separated from the evaporation tank storing industrial wastewater. In practical use, the industrial wastewater tank can only be used for evaporation treatment, resulting in a limited applicability. Furthermore, the heating equipment is exposed to the highly corrosive and chemically reactive environment of industrial wastewater for extended periods, leading to faster aging and corrosion. Consequently, the heating tubes require frequent repair and maintenance, which is detrimental to reducing the operating costs of industrial wastewater evaporation equipment. Therefore, this invention proposes a modular evaporation device for industrial wastewater discharge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a modular evaporation device for industrial wastewater discharge, including an evaporation tank and a support base.

The heated and evaporated industrial wastewater will generate water vapor, which rises and enters the inside of the exhaust pipes. The exhaust pipes are connected to the top connecting pipe via a mounting flange. The other side of the connecting pipe is used to connect to the filtration and purification equipment for the polluted water vapor. Therefore, the connecting pipe can be removed from the top of the transparent cover.

The anti-corrosion layer can reduce the corrosion of the concrete evaporation tank by chemicals. The upper crossbeam and the lower support frame are both made of corrosion-resistant aluminum alloy. Multiple ceramic tubes with internal heating wires are vertically installed between the upper crossbeam and the support frame. When the multiple heating tubes are powered on, they can generate heat to heat the industrial wastewater inside the evaporation tank.

[0026] Working principle: Modular evaporation equipment for industrial wastewater discharge can heat and evaporate polluted wastewater generated from industrial processing and production, such as wastewater containing chemical salts. After evaporation, the salts can be extracted, making it easier to purify the wastewater. The support base 2 is made of precast concrete, and together with the concrete evaporation tank 1, it can have a large volume to store industrial wastewater. The top cover 31 has a larger area than the top of the evaporation tank 1, so the top cover 31 can be snapped onto the top of the evaporation tank 1 to complete the assembly. The sealing strip 33 is a rubber material filled between the bonding block 32 and the outer wall of the evaporation tank 1. The bonding block 32 and the evaporation tank 1 are installed by tightening with bolts.

The entire top cover is set separately from the evaporation tank and can be separated into two separate modular bodies from the evaporation tank 1. The top cover 31, together with the internal structure above it, can be directly installed on the top of other evaporation tanks 1, making it more applicable. The transparent cover 41 is fixedly connected to the top of the outer cavity 34. The transparent cover 41 is made of aluminum alloy material with internally embedded transparent glass. The transparent cover 41 has downward sloping sides, so it can drain rainwater and does not block sunlight. The transparent cover 41 is fixedly connected to two exhaust pipes 42. The industrial wastewater that has been heated and evaporated will generate water vapor. The water vapor can rise and enter the inside of the exhaust pipe 42. The exhaust pipe 42 is connected to the top connecting pipe 43 by the mounting flange 44. The other side of the connecting pipe 43 is used to connect the filter and purification equipment for polluted water vapor. Therefore, the connecting pipe 43 can be removed from the top of the transparent cover 41. The anti-corrosion layer 55 is a ceramic layer bonded to the bottom of the evaporation tank 1. The anti-corrosion layer 55 can reduce the corrosion of the concrete evaporation tank 1 by chemical substances. The upper crossbeam 51 and the lower bottom bracket 54 are both made of corrosion-resistant aluminum alloy welded together. Multiple ceramic tubes with internal heating wires are vertically installed between the upper crossbeam 51 and the bottom bracket 54. When the multiple heating tubes 53 are powered on, they can generate heat to heat the industrial wastewater inside the evaporation tank 1. The increase in temperature will cause the industrial wastewater to boil and evaporate. After the modular top cover 31 is removed, the heating assembly composed of the upper crossbeam 51 can be lifted upward by the lifting equipment tied to the suspension block 52, which is convenient for maintenance and replacement and reduces the cost.
