Embodiment 1

[0041] combine Figure 6 As shown, the multi-component VOCs waste gas 7 enters the honeycomb activated carbon adsorption area, and most of the organic waste gas such as dust, moisture and odor is absorbed, and then passes through the molecular sieve runner, the waste gas is further purified, and the purified gas 10 is emptied Or for other purposes. During this process, the thickness ratio and total thickness of the honeycomb activated carbon runner and the molecular sieve runner are designed and adjusted according to the exhaust gas components and on-site working conditions, and various parameters are adjusted in due course according to the operating conditions. When the adsorption is saturated, it enters the desorption area, and the air 4 and the outlet gas 8 of the cooling area are heated by the electric heating device 9 to become high-temperature air with a temperature of 100-300°C, which is preferentially desorbed from the molecular sieve runner, and the high-temperature a...

Abstract

The invention discloses a compound VOCs absorbing concentration turning wheel and a use method thereof and belongs to the technical field of absorption of organic gas. The compound VOCs absorbing concentration turning wheel is formed by coaxially equal-diameter butt-jointing a molecular sieve turning wheel and a honeycomb activated carbon turning wheel, wherein the honeycomb activated carbon turning wheel is located on a VOCs inlet side; an absorbing area, a desorption area and a cooling area are arranged on each turning wheel; an isolating ring is arranged at the butt-joint of the two turning wheels; the isolating ring is used for isolating the absorbing areas, the desorption areas and the cooling areas of the two running wheels, redistributing wind and reducing wind resistance; the molecular sieve turning wheel is acquired by attaching the VOCs adsorbent to the honeycomb turning wheel in the manner of spraying, leaching or impregnating. According to the invention, the molecular sieve turning wheel and the honeycomb activated carbon turning wheel are combined with each other, so that the absorbing scope is widened, the purifying efficiency is increased, the quality of purified gas is further ensured and the occupied space of equipment is saved.

Description

technical field [0001] The invention relates to the technical field of adsorption of organic gases, in particular to a composite VOCs adsorption and concentration runner and a method for using the same. Background technique [0002] In the printing, coating, and optoelectronic industries, the exhaust gas usually has the characteristics of low concentration, large air volume, variable and complex composition. Conventional treatment methods such as direct combustion, catalytic combustion, etc. are used to deal with this low-concentration, high-air volume VOCs Not only can it not be completely combusted, but also increases energy consumption. Therefore, concentrated adsorption runners are increasingly widely used, such as honeycomb activated carbon adsorption runners, molecular sieve adsorption runners, etc. [0003] However, no matter whether honeycomb activated carbon or molecular sieve runner is used alone, the components in VOCs cannot be completely adsorbed. The structure...
