Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical production, and specifically relates to a purification device for industrial sewage treatment. Background Art
[0002] Chemical production includes liquid, solid or gas reactions, especially the production of liquid chemical materials. The components are often added in excess and mixed together. In this way, in addition to the products required by the process, there will be residual raw liquid mixed with the products. In order to purify industrial wastewater, the mixed liquid in the mixing tank is generally heated and fractionated and purified by using the different boiling points of each component.
[0003] In the prior art, when purifying liquid chemical materials, the liquid is heated by an electric heating wire while being stirred by a mixing shaft. However, the electric heating wire is wrapped around the outside of the mixing tank, and the heating surface is annular, which makes it inconvenient to heat the middle part of the liquid. Stirring by the mixing shaft is required, which leads to increased power consumption of the purification device. For this reason, we propose a purification device for industrial wastewater treatment.

Since the mixing tank is flat and has a wave shape, the liquid heating area is larger than that of traditional purification devices, and there is no need to stir the liquid, which is beneficial to reducing the power consumption of the purification device. Then, the components with low boiling points in the liquid are evaporated and detached along the outlet pipe, and the excess steam is discharged along the steam output pipe, which is convenient for recovering the waste heat of the steam for preheating the liquid.

When liquid is loaded, it is drained along the hard tube and transported to each atomizing nozzle respectively, and is evenly sprayed into the mixing tank through the atomizing nozzle, which facilitates uniform distribution of liquid, reduces aggregation, and is beneficial to increasing the heated area.
[0009] An electric regulating valve is installed on the outer side of the steam input pipe, and the opening and closing degree of the electric regulating valve can be controlled to change the flow rate of steam in the steam input pipe.
[0010] The outside of the steam box is wrapped with an insulation layer, and one end of the liquid inlet pipe, one end of the air outlet pipe and one end of the steam input pipe all extend out of the insulation layer, so that the outside of the steam box is insulated to reduce the heat lost from the steam box to the air, which is conducive to concentrating the heat of the steam box on the mixing tank.
[0011] A drain pipe is installed through the lower end of the mixing tank, one end of the drain pipe extends out of the insulation layer and is equipped with a sampling valve. During the purification process, one end of the drain pipe is closed, and the sampling valve can be used to take samples to detect the purity of the liquid. After the purity is qualified, one end of the drain pipe is opened to discharge the material.
[0012] Support legs are fixedly installed on both sides of the lower end of the steam box, and the lower ends of the two legs extend out of the insulation layer to provide support, so as to facilitate the suspension of the purification device and prevent the lower surface of the insulation layer from being squeezed.
