Problems solved by technology

However, the organic waste gas emitted by different industries generally has complex components. For example, the organic waste gas discharged under some working conditions will have a relatively large water content. It has been proved by experiments that there is a competitive adsorption between water molecules and VOCs components when adsorbed by molecular sieve adsorption wheels. phenomenon, which reduces the purification efficiency of molecular sieves for organic waste gas and shortens the length of the adsorption band
[0003] The technical development of dehumidification molecular sieve is relatively mature, but it is generally used alone. Installing an additional dehumidification wheel before the molecular sieve wheel will not only increase the cost and increase the cost, but also occupy additional space, which is not good for users and enterprises.

preparation example Construction

[0046] The method for preparing the dual-function adsorption runner with the above two runner structures specifically includes the following steps:

[0047] The first step is to use fiber material to make two porous honeycomb structure carriers, which are used as two runners for backup. The fiber material can be one or more of ceramic fiber, glass fiber, activated carbon fiber, and synthetic fiber. mixture;

[0048] Step 2. Mix 0.1-50 parts by weight of adsorbent molecular sieve, 0.1-50 parts of dehumidifier molecular sieve, respectively, with 0.1-80 parts of inorganic binder such as silica sol or aluminum sol, and 0.1-300 parts of water. , Respectively make adsorbent slurry and desiccant slurry;

[0049] Step 3: Choose dipping, spraying or rinsing to load the adsorbent slurry evenly on one of the runners, and load the dehumidifier slurry evenly on the other runner;

[0050] Step 4: Drying with hot air or microwave for 0.1-24 hours, and docking two runners to obtain a dual-function c...

Embodiment 1

[0064] Combine Figure 5 As shown, the VOCs exhaust gas 6 with a certain moisture content preferentially enters the dehumidification zone 1, the moisture in the exhaust gas is removed and then enters the molecular sieve runner adsorption zone 2, and the VOCs exhaust gas is adsorbed to obtain purified gas 9. In this process, the thickness ratio and total thickness of the dehumidification runner and the molecular sieve runner are designed and adjusted according to the moisture content of the exhaust gas and the site conditions, and various parameters are adjusted in time according to the operating conditions. When the adsorption is saturated, it enters the desorption zone. The air 3 and the outlet gas 7 of the cooling zone are heated by the electric heating device 8 to obtain high-temperature air with a temperature of 100-300℃. The molecular sieve runner is preferentially desorbed, and the high-temperature air passes After the molecular sieve runner, the temperature drops to 80-15...

Abstract

The invention discloses a bi-functional adsorption and concentration rotating wheel achieving dehumidifying and VOCs removing, and belongs to the technical field of organic gas adsorption and purification. The bi-functional adsorption and concentration rotating wheel is composed of a first rotating wheel and a second rotating wheel, the diameter of the first rotating wheel and the diameter of the second rotating wheel are the same, adsorbing agents evenly stick to the first rotating wheel, dehumidizer evenly sticks to the second rotating wheel, the first rotating wheel and the second rotating wheel are in coaxial butt joint with the second rotating wheel in a gapless mode, and the second rotating wheel is located on the VOCs inlet side; or the bi-functional adsorption and concentration rotating wheel is composed of a first rotating wheel which is provided with a dehumidifying area and an adsorption area, the dehumidizer is evenly distributed on the dehumidifying area, and the adsorbing agents are evenly distributed on the adsorption area. According to the bi-functional adsorption and concentration rotating wheel achieving dehumidifying and VOCs removing, dehumidifying and adsorption are integrated on the same rotating wheel, the proportion of the VOCs adsorption part and the dehumidifying part can be adjusted according to needs, the occupied space of equipment is saved, and meanwhile the double functions of dehumidifying and VOCs removing are achieved.

Description

Technical field [0001] The invention relates to the technical field of organic gas adsorption and purification, in particular to a dual-function adsorption and concentration runner for dehumidification and VOCs removal. Background technique [0002] Molecular sieve runners have a wide range of applications in the field of processing VOCs, especially suitable for low-concentration, high-volume organic waste gas occasions, such as photoelectric, spray printing and other industries. However, the general composition of the organic waste gas discharged by different industries is more complicated. For example, the water content of the organic waste gas discharged under some working conditions will be relatively large. Tests have proved that when the molecular sieve adsorption wheel is adsorbed, there is a competitive adsorption of water molecules and VOCs components. This reduces the purification efficiency of molecular sieve for organic waste gas and shortens the length of the adsorpt...
