The application discloses a defoaming device of falling film evaporator, which comprises a shell, the shell is provided with a steam inlet at the bottom and a steam outlet at the top, at least one vertical defoaming channel and a steam guiding mechanism are arranged in the shell, the defoaming channel is provided with an input port connected with the steam inlet and an output port connected with the steam outlet, the steam guiding mechanism is used for guiding steam to flow into the input port of the defoaming channel, and the width of the defoaming channel gradually decreases along the guiding direction of the steam guiding mechanism. The application has the beneficial effects of improving the defoaming effect and efficiency.

The invention discloses a preparation method of lead-free metallic luster glaze, which is characterized in that a formula system is constructed by introducing lead-free raw materials such as calcium borate frits and recycling steel slag, and coloring ions (Co < 2 + >, Fe < 3 + >, Mn < 2 + > and the like) are promoted to be uniformly distributed in a network structure, so that a glaze layer is endowed with the characteristics of environmental protection, high glossiness and stable color. The production cost is effectively reduced, the remarkable problems of the traditional lead-containing glaze in the aspects of environmental protection and safety are effectively solved, and the lead-containing glaze can be widely applied to the fields of art, daily use and architectural ceramics.
