Description

Movable's VOC administers device

Technical Field

The utility model relates to a waste gas treatment technical field refers in particular to a movable VOC administers device.

Background

Enterprises in petrifaction, pharmacy, chemical industry, coating, printing and the like are important source enterprises generating VOC, and because the enterprises need to use a large amount of organic solvents in the production process, the treatment of the VOC is an urgent problem to be solved for the enterprises.

For organized emission, generally, the VOC gas collected from the waste gas generating source is uniformly transported to a waste gas treatment device through a pipeline for uniform treatment, but in the coating and pharmaceutical industry, the VOC concentration of some factories is very high, the air volume is very small, or the air volume of the whole factory production workshop is very large, but the concentration is very low, and at the moment, the calculation of the filling amount of the adsorbent according to the traditional method is obviously not economical. Especially for dead corner positions of some workshop parts, the VOC concentration is difficult to be reduced by increasing the cycle times, and at the moment, the movable VOC treatment device with small air volume and similar to the action of an air purifier

The method for treating organic waste gas which is already mature and commercialized at present mainly comprises the following steps: adsorption, low-temperature plasma, UV photolysis, catalytic combustion, and the like. Among them, the adsorption method has been used for centuries as a typical method for removing adsorbable VOC from exhaust gas or recovering solvent.

The principle of adsorption is: the gas components (adsorbates) to be separated in the gas phase can be selectively bound to the solid surface (adsorbent) and then returned to the gas phase by desorption (desorption). In general, adsorption is classified into physical adsorption, which is a reversible adsorption by only weak interaction, whose energy is generally less than 63-84kJ/mol, and chemical adsorption, in which liquid or gas molecules are bound on the surface of a solid material by van der waals force, dipole-dipole interaction, hydrogen bond, or the like. For a given solid adsorbent, the higher the degree of dispersion (specific surface area), the greater the surface energy, and the less stable the system. In order to make the system tend to be in a relatively stable state, the surface tends to lower the surface energy by adsorbing gas molecules. The method for purifying VOC waste gas mainly adopts a physical adsorption method. Compared with other methods, the adsorption method can absorb components with very low concentration (even trace amount), and can greatly increase the concentration after desorption, so that the solution steam can be removed from the waste gas and finally the solvent can be recovered through separation.

The amount of adsorbate adsorbed by a quantity of adsorbent at a certain temperature and pressure (or concentration) is referred to as the adsorption quantity. In the case of gas-solid adsorption, the adsorption amount is closely related to the temperature, pressure, etc., in addition to the adsorbent and the adsorbate itself. In the range of smaller pressure, the adsorption quantity is sharply increased along with the increase of the gas pressure, and the increasing speed of the adsorption quantity is gradually slowed down along with the increase of the pressure until the adsorption surface is saturated; the temperature also has a great influence on the adsorption capacity, the low temperature is favorable for adsorption, and the adsorption capacity is gradually reduced along with the temperature rise.

The adsorption material with reasonable selection and design is an important branch in the research of adsorption science, the main basis for selecting and designing the adsorbent aiming at the molecules of a specific target adsorbent is an adsorption isotherm, but for the VOC gas mixed with a plurality of adsorbents, whether the pore size of the adsorbent is matched with the molecular size of the adsorbent or not is an important design parameter. The adsorption separation materials are divided into two categories of inorganic materials and organic polymer materials. From the viewpoint of the chemical structure of the material, the adsorption separation material can be classified into three types, i.e., inorganic adsorbent, polymeric adsorbent and carbonaceous adsorbent. The inorganic adsorbent is an inorganic compound with a certain crystal structure, most of which are natural inorganic substances, such as zeolite, montmorillonite and the like, wherein the most widely used inorganic adsorbent is synthetic silica gel and a molecular sieve. The organic polymer adsorbent is polymerized from monomers, and can be used for preparing adsorbing materials with different structures by changing the composition of the monomers and the polymerization method, and in addition, the materials can be further modified by a chemical method to prepare adsorbing materials with various functional groups, such as organic molecular sieves and the like. The carbon adsorbent is a material between an inorganic adsorbent and an organic adsorbent, and comprises activated carbon, activated carbon fiber and the like, the material has wide sources and low cost, and is sought after in recent years, but the problems of chemical adsorption and safety exist. The zeolite molecular sieve has the characteristics of easily available materials, large adsorption capacity, high mechanical strength and the like, but because the zeolite molecular sieve is not acid-base resistant and has overlarge wind resistance in the adsorption process, the adsorption efficiency is greatly reduced, and the zeolite molecular sieve is not suitable for a movable VOC treatment device.

Therefore, in recent years, organic molecular sieves have begun to receive attention from material chemists and the industry as a safe and efficient physical adsorbent, and have begun to be applied in the treatment of VOCs in engineering.

It is thus clear that the device is administered to VOC among the prior art exists not enoughly, and current VOC administers the device and generally including desorption device, leads to VOC to administer the volume of device great, inconvenient removal or transportation.
