Embodiment Construction

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] This embodiment discloses a system for automatically recovering acetic acid from ceramic leaching waste liquid.

[0034] The system is divided into storage heat dissipation device, power heating device, cooling device, collection device, funnel communicator and control device, etc., and is implemented by selecting manual mode or automatic mode through the operation control panel.

[0035] For the structure of the system, see Figure 1-4 ,

[0036] See figure 1 , The storage heat dissipation device is composed of a liquid storage tank 1 and a communication valve 17. The liquid storage tank 1 is a rectangular body and is provided with two cavities a and b. The cavity b used for recovering and storing the reaction liquid flowing back and cooling down the temperature is connected to the overflow pipe 8 . A communication valve 17 is provided at the lowe...

Abstract

The invention discloses a system for automatically recycling acetic acid from ceramic leaching liquid waste, wherein a liquid level sensor and a temperature sensor are installed in the cavity body of a liquid storage pool used for storing a radiating device, and the liquid storage pool is connected with a power heating device through a pipeline; the inlet of the circulating pump of the power heating device is connected with the liquid storage pool, and the outlet of the circulating pump power is connected with a cooling device; a cooler of the cooling device is connected with a reaction mainframe; a recycling pool liquid level sensor is installed in a pure acetic acid-water recycling pool of a collecting device, one end of a pure liquid pipe is connected with the cooler, and the other end of the pure liquid pipe is inserted into the pure acetic acid-water recycling pool; a control device comprises a main control PLC (programmable logic controller), a frequency changer, sensors and a relay; the circulating pump is connected with the main control PLC through the frequency changer, the sensors are respectively connected with the main control PLC, and the system adopts PLC control to effectively separate out lead and cadmium heavy metal ions so as to obtain an acetic acid solution capable of being used for soaking ceramic again, reduce the environmental pollution and recycle resources.

Description

technical field [0001] The invention relates to a harmless treatment and recycling system mainly applied to low-concentration acetic acid waste liquid, especially for soaking ceramic products whose concentration is less than 4% and containing lead and cadmium [0002] An automatic control system for the harmless treatment and recovery of heavy metal ion acetic acid solution, specifically [0003] It is said to be a system for automatically recovering acetic acid from ceramic leaching waste liquid. Background technique [0004] For the detection of the dissolution of heavy metals such as lead and cadmium in ceramic products in contact with food, the current international and domestic method is to soak in 4% acetic acid solution for detection. In order to obtain accurate test data, the acetic acid solution needs to fully contact the surface of ceramic products. This test process produces a large amount of waste acetic acid solution with low concentration and may contain lead ...
