Background
The foaming agent is a substance for forming pores in a target substance and can be classified into a chemical foaming agent, a physical foaming agent and a surfactant. Chemical blowing agents are those compounds which decompose upon heating to release gases such as carbon dioxide and nitrogen and form pores in the polymer composition; physical blowing agents are those in which the foam cells are formed by a change in the physical form of a substance, i.e., by expansion of a compressed gas, volatilization of a liquid, or dissolution of a solid; the foaming agents have higher surface activity, can effectively reduce the surface tension of liquid, are arranged on the surface of a liquid film in an electric double-layer mode to surround air to form bubbles, and then form foam by single bubbles. The pentane foaming agent at the present stage utilizes a float valve tower to carry out rectification separation work so as to achieve the purpose of improving the purity of the pentane foaming agent, and the float valve tower is a novel tower type developed and is characterized in that a valve plate capable of moving up and down is installed at each sieve pore. When the air speed of the sieve holes is high, the valve plate is jacked up and rises, and when the air speed is low, the valve plate falls due to the self weight. The lifting position of the valve plate is automatically adjusted along with the air flow, so that the air speed entering the liquid layer is basically stable. And because the gas enters the liquid layer in the horizontal direction under the valve plate, the liquid foam entrainment amount is reduced, and the gas-liquid contact time is prolonged. The float valve tower has good gas-liquid contact state, small entrainment (due to horizontal gas blowing), high tower plate efficiency and high production capacity.
The floating valve mainly has two types of V type and T type, because the connecting rod external diameter of the valve gap of T type is less than the valve frame internal diameter, the whereabouts orbit of messenger's valve gap skew can not the complete closure valve gap, consequently, prior art exists not enoughly, needs to improve this.
