A gas collection device for liquid raw material feeding and mixing system

Abstract

The invention discloses a gas collection device for liquid raw material feeding and mixing system, which includes a gas collection box, a top-suction gas collection hood arranged at the top opening of the gas collection box, and an automatic control system. There are air inlets on the left and right sides, and a number of raw material pipe joints used to connect the raw material barrels and raw material delivery pipelines are fixed and sealed on the back by surfacing welding. The automatic control system includes a valve automatic control system, a temperature automatic control system, a mixing zone gas system. The present invention makes the collection of unorganized exhaust gas in the feeding and mixing links more stable, more accurate and more thorough through the electrical connection of each control system; the unorganized exhaust exhaust gas in the mixing link is collected; the size of the raw material storage room is designed as The standard size of the forklift load plate enables standardized operation of loading and unloading of raw material barrels, improves the standardization, automation and integration of the device, is suitable for feeding and mixing of various liquid raw materials, and improves the gas collection efficiency of the gas collection device of the feeding system.

Description

technical field [0001] The invention relates to the technical field of industrial ventilation equipment, in particular to an environment-friendly gas collection device for liquid raw material feeding and mixing systems. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, VOCs) refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure. VOCs emitted by industrial enterprises are carcinogenic, teratogenic, and mutagenic. They not only seriously endanger human health, but are also fine particulate matter (PM 2.5 ) and photochemical smog and other important precursors of secondary pollutants have played an important role in my country's recent atmospheric compound pollution. In recent years, the governance of VOCs has received great attention. [0003] VOCs emitted in industrial production include process exhaust gas and workshop exhaust gas. Process wa...

AI Technical Summary

Problems solved by technology

First of all, the vapor pressure of some raw materials is greatly affected by temperature. Controlling the temperature of the raw material chamber can effectively reduce solvent volatilization and fundamentally reduce the fugitive emission of waste gas. However, the above two improvements have not considered this; secondly, standardization, overall The standardized feeder has a wider range of applications, can be adapted to different industrial processes, and is also conducive to the efficient operation of the factory. However, the above two improvements have not considered the problem of standardized design
