Technical Field

[0001] The utility model relates to the field of waste liquid recovery devices, in particular to an environmentally friendly chemical waste liquid recovery device. Background Art

[0002] If chemical waste liquid is discharged without treatment, it will cause pollution of different properties and degrees in water bodies, thereby endangering human health and affecting industrial and agricultural production. Chemical waste liquid must be centrally recovered before being treated to prevent waste liquid leakage from causing harm to the environment and human life.

[0003] Traditional environmentally friendly chemical waste liquid recovery devices usually require a large amount of energy to carry out the waste liquid heating and separation process, which results in serious energy waste and may not be able to efficiently separate and recover useful components in the waste liquid, resulting in waste of resources. Therefore, those skilled in the art provide an environmentally friendly chemical waste liquid recovery device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an environmentally friendly chemical waste liquid recovery device. During the waste liquid treatment process, the heat generated by the heater is transferred to the heating chamber in the water tank through the heat transfer pipe. After the air in the heating chamber is heated and heated, the heat is transferred back to the waste liquid treatment tank through the heat transfer pipe to form a heat circulation loop. This design not only improves the heat utilization efficiency and reduces energy waste, but also can heat the water in the water tank. The hot water can be used for other purposes, further improving the energy utilization rate. The peristaltic pump draws waste liquid from the waste liquid treatment tank through the suction pipe and transports it to the sampling bottle in the waste liquid recovery tank. The flow meter can monitor the flow of waste liquid in the suction tube in real time, thereby accurately controlling and adjusting the recovery process. It not only improves the efficiency and accuracy of waste liquid recovery, but also optimizes the recovery process based on real-time data to ensure that the recovered waste liquid meets specific standards or requirements. By flexibly replacing or adjusting the specifications and performance of the filter, activated carbon and adsorption cotton according to different waste liquid components and treatment requirements, the device's ability to treat various chemical waste liquids is improved. This modular design is not only convenient for maintenance and replacement, but also can optimize the filtration effect according to actual needs and extend the service life of the device.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an environmentally friendly chemical waste liquid recovery device, comprising a waste liquid treatment box, a control panel provided at the lower center of the front end surface of the waste liquid treatment box, a liquid inlet provided at the center of the upper end surface of the waste liquid treatment box, a filtering and purification structure provided at the upper center of the interior of the waste liquid treatment box, a drainage flow structure provided at the lower center of the interior of the waste liquid treatment box, a heat recovery structure provided on one side of the waste liquid treatment box, and a waste liquid recovery structure provided on the other side of the waste liquid treatment box;

[0006] Through the above technical solution, during the waste liquid treatment process, the heat generated by the heater is transferred to the heating chamber in the water tank through the heat transfer pipe. After the air in the heating chamber is heated and heated, the heat is transferred back to the waste liquid treatment tank through the heat transfer pipe, forming a heat circulation loop. This design not only improves the efficiency of heat utilization and reduces energy waste, but also heats the water in the water tank, and the hot water can be used for other purposes, further improving energy utilization. The peristaltic pump draws waste liquid from the waste liquid treatment tank through the suction pipe and transfers it to the sampling bottle in the waste liquid recovery tank. The flow meter can monitor the flow rate of the waste liquid in the suction pipe in real time, thereby accurately controlling and adjusting the recovery process.

[0008] Through the above technical solution, when the chemical waste liquid enters the waste liquid treatment box from the liquid inlet, it first flows through the filtration and purification structure, and the waste liquid passes through three sliding boxes in turn. In this process, first, the waste liquid passes through the sliding box equipped with a filter screen, and the filter screen intercepts larger granular impurities in the waste liquid, such as solid particles, suspended matter, etc. Then, the waste liquid enters the sliding box equipped with activated carbon, and the activated carbon removes organic matter and some harmful substances in the waste liquid through adsorption, such as some organic dyes, heavy metal ions, etc. Finally, the waste liquid passes through the sliding box equipped with adsorption cotton, and the adsorption cotton further adsorbs tiny particles and residual impurities, so that the waste liquid is more thoroughly purified.

When the treated waste liquid needs to be discharged, the discharge solenoid valve is opened to allow the waste liquid to flow smoothly into the inclined flow trough. When it is not necessary to discharge, the discharge solenoid valve is closed to allow the waste liquid to continue to be processed in the treatment box or wait for further operation. Eight heaters heat the waste liquid on the liquid guide plate to accelerate the evaporation of water in the waste liquid or the progress of specific chemical reactions. According to different waste liquid treatment requirements, the heating temperature and time of the heater can be adjusted to achieve the best treatment effect.
