Description

technical field [0001] The invention relates to a purification device, in particular to a dioctyl ester recovery device. [0002] Background technique [0003] Dioctyl Phthalate (Dioctyl Phthalate), referred to as Dioctyl Phthalate (DOP), is an ester organic compound and a commonly used plasticizer. In the catering industry and manufacturing industry, a large amount of oil, smoke, mist, dust, etc. will be produced. The ingredients are edible oil, DOP, resin, flame retardant, xylene, etc., and have a strong pungent smell. These gases volatilize into the air, causing great pollution to the environment. The current treatment method is to discharge the exhaust gas through the chimney after water condensation and physical filtration. However, the efficiency of this waste gas removal is relatively low and does not meet the environmental protection requirements. DOP has a relatively large molecular weight of 390, and the average molecular weight of air is 29, so it is not easy ...

AI Technical Summary

Problems solved by technology

[0006] First, the gas entering the high-voltage electrostatic generator in the electrostatic recovery device is not uniform, and an air equalization system needs to be added. The oil fume can be uniformly ionized and decomposed in the electric field, and the insulation effect of the insulator in the high-voltage electrostatic generator is not good. , prone to positive and negative short circuit phenomenon, poor recovery effect;

[0007] Second, the recovery equipment runs for too long, and there are too many oil stains attached to the high-voltage electrostatic generator, which affects the recovery efficiency. The high-voltage electrostatic generator in the existing dioctyl ester recovery equipment is fixed in the electrostatic recovery device, which is not easy to clean ;

[0008] Third, the existing high-voltage electrostatic generators are connected by cables. Since there are oil, water and other corrosive substances inside the dioctyl ester recovery equipment, if they are connected by cables, the corrosion resistance of copper is relatively poor.

The internal corrosive substances will corrode the copper wire of the cable, so that the overall connection effect will not be achieved, and it will cause the danger of internal electric field ignition

[0009] Fourth, there are two elements of the three elements of explosion in the recovery equipment of dioctyl ester, namely oil and electric spark, so it is more likely to produce an explosion during operation than other purification equipment, while the existing explosion-proof not effectively;

[0010] Fifth, when an open flame appears in the electrostatic recovery device, under most working conditions, the controller controls the equipment to stop, and the operator then extinguishes the fire. The fire is likely to grow rapidly, which is unsafe
