Embodiment Construction

[0025] Specific embodiments are provided below and the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0026] Such as figure 1 As shown, the zirconia powder production waste liquid recovery device of the present invention includes a solar evaporation pool 1, and the solar evaporation pool includes side walls and bottoms, and the side walls and the bottom surround a container for treating waste liquids. setting space.

[0027] A layer of solar heat absorbing bottom plate 2 is laid on the bottom in the solar evaporation pool 1 . The solar heat-absorbing bottom plate is composed of a substrate 21 and a heat-absorbing coating 22 , and the heat-absorbing coating 22 is laid on at least one side of the substrate 21 . Substrate 21 is flat plate shape usually, also can be the shape of other existing solar heat absorbing panels such as corrugated shape, fin shape etc.; The ma...

Abstract

The invention discloses a recovery device for zirconium oxide powder production waste liquid. The recovery device comprises a solar evaporation tank, a solar heat absorption bottom plate laid at the bottom in the solar evaporation tank, a liquid inlet, a liquid outlet, an air inlet, an air outlet, a transparent cover plate and the like. According to the recovery device, waste liquid flows throughthe solar evaporation tank with the solar heat absorption bottom plate, the waste liquid is heated, evaporated and concentrated by solar energy, low-cost waste liquid recovery is realized, the requirement of cost control of a production enterprise is met, the concentrated waste liquid can be used as a fertilizer or a fertilizer raw material, and waste is turned into wealth. The recovery device isreasonable in design, simple, practical, low in recovery cost, high in recovery efficiency, energy-saving, environment-friendly and particularly suitable for large-scale treatment of zirconium oxide powder production waste liquid.

Description

technical field [0001] The invention relates to a recovery device for waste liquid produced by zirconia powder, and belongs to the technical field of environmental protection equipment. Background technique [0002] The current common co-precipitation process for producing zirconia powder will produce waste liquid containing chloride ions and ammonium ions or sodium ions. These waste liquids are produced by repeated washing, so the concentration of harmful ions is low, only 3- 5%, cannot be directly recycled, but the direct discharge does not meet the environmental protection requirements, so it cannot be directly discharged. Therefore, it is necessary to concentrate the waste liquid and recover the chloride ions, ammonium ions or sodium ions therein, so that the waste liquid can be turned into treasure. [0003] The current method is to treat the waste liquid by heating, evaporating and concentrating with a heat source such as a boiler, but it needs to consume a lot of ext...
