Вихревой пылеуловитель

Номер: RU0000167446U1
Автор: Денис Николаевич Ватузов, Денис Николаевич Тюрин, Николай Павлович Тюрин, Светлана Михайловна Пуринг
Принадлежит: федеральное государственное бюджетное образовательное учреждение высшего образования "Самарский государственный технический университет"

Полезная модель предназначена для мокрой инерционной очистки спутных закрученных газовых потоков и может применяться в горной, химической, текстильной промышленности.Техническим результатом полезной модели является повышение эффективности работы пылеулавливающего устройства, повышение качества очищаемого воздуха и снижение энергозатрат при очистке запыленного воздуха.Технический результат достигается тем, что в предложенном вихревом пылеуловителе обеспечивается повышение эффективности процесса пылеулавливания путем снижения уноса пыли за счет предварительного орошение потоков запыленного воздуха, поступающего в пылеуловитель, что приводит к укрупнению пылевых частиц, сепарация которых значительно увеличивается. Кроме этого орошающая жидкость, оседая на внутренней поверхности сепарационной камеры, препятствует отскоку пылевых частиц от сепарационной камеры и способствует их улавливанию и смыванию в сборный бункер.Использование приспособления в виде низкоскоростной трубы Вентури в вихревом пылеуловителе позволяет снизить энергозатраты при очистке запыленного воздуха. 4 з.п. ф-лы, 2 илл.

This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas.

A system and method for particle enlargement with continuously wetted wicks includes a container into which a flow of particle-laden air is introduced in a laminar manner through an inlet and to an outlet. The container has a first section, a second section and a third section though which the particle-laden air flows between the inlet and the outlet. The temperature of the second section is warmer than that of the first section at the inlet and the third section at the outlet. In one embodiment, a continuous wick spanning an interior wall of the first second, second section and third section, said wick being capable of internally transporting liquid water along its length is provided. Alternatively, a wick characterized by a bubble point pressure has one side in contact with air and an opposing side mounted adjacent to the interior wall of a housing with a gap formed between the wick and the housing, wherein the wick is used with a water reservoir such that the pressure difference between the air flow and the water filled gap is less than the bubble point pressure of the wick material.

Process for making solid particles

Принадлежит: Procter and Gamble Co

The invention relates to a process of creating particles of controlled size by creating them in the interstitial regions in a continuous liquid phase that contains a second, inert gas phase at high volume fraction; namely a foam. The second phase creates a physical barrier that limits the aggregation of formed particles beyond the size of the narrow interstitial regions occupied by the continuous phase. This technique is useful when the particles normally create large aggregates due to the fast nature of the reaction and the strong attractions between the formed particles, and for enhancing the deposition of high-value materials by connecting them to coacervates of controlled size.

This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas. 1) A method for removing a solid contaminant from ambient air within an enclosed building , said method comprising: i) at least one compound, wherein at least one of said at least one said compound is a semi-volatile organic compound; and', 'ii) water;, 'a) obtaining a liquid mixture, said liquid mixture comprisingb) optimize the temperature of the room;c) spraying in an atomized form said liquid mixture into said ambient air of and within said enclosed building to remove said solid contaminant;d) allowing for said atomized form of said liquid mixture to intermingle with said solid contaminant in the ambient air;e) spraying a second spray in an atomized form into said ambient air of and within said enclosed building to assist in the settling of said liquid mixture now containing said solid contaminants, said second spray being comprised of water;f) allowing for said second spray and said liquid mixture containing said solid contaminants to be pulled down by gravity until said liquid mixture and second spray now containing said solid contaminant falls from the ambient air to land on a surface; andg) removing said liquid mixture and said second spray containing said solid contaminant from said surface upon which said liquid mixture containing said ...
