Today, Jiangsu Kunzheng Environmental Technology Co., Ltd. will introduce packing sheet to you. Packing sheet, also known as packing cluster sheet or packing sheet, refers to a relatively stable structure of the use of packing materials made of fragmented granulation. The main function of the filler sheet is to increase the surface area, increase the effect of material transfer, and then improve the reaction conversion rate. Packing sheet is mainly used in various chemical equipment, such as adsorption tower, desulfurization tower, condensing tower and so on.

When choosing a suitable packing sheet, the following aspects need to be considered:

1. Physical characteristics: including the shape, size, specific surface area and packing density of the packing sheet. The shape can be divided into round, square, toothed, etc., and the size and specific surface area directly affect the internal and external mass transfer rate of the packing sheet. Packing density refers to the ratio of the weight of the packing sheet to the volume, usually choosing a lower packing density can increase the convenience and flexibility of the packing.

2. Chemical properties: mainly including the corrosion resistance and temperature resistance of the packing sheet. Under different chemical process conditions, it is necessary to choose the packing sheet that ADAPTS to the corresponding environment. For example, in equipment that works in an acidic environment, it is necessary to choose a packing material with good corrosion resistance.

3. Economy: Economy is an important consideration in the selection of packing sheet. Including packing price, service life, cleanliness and so on. In general, the lower the price, the longer the service life, the higher the economy.

Of course, in the specific selection of packing plates, it is also necessary to consider the specific process parameters and equipment requirements. The following is a detailed description of several commonly used packing sheets:

1.Glass fiber packing sheet: glass fiber packing sheet is a commonly used packing sheet, with good corrosion resistance and high mass transfer effect. Suitable for some demanding chemical equipment, such as acid gas absorption, drying and condensation.

2. Plastic packing sheet: There are many kinds of plastic packing sheet, common polypropylene, PVC and so on. Plastic filler sheet has low cost and good corrosion resistance, and is suitable for some general chemical equipment.

3. Ceramic packing sheet: Ceramic packing sheet is mainly used in high temperature and corrosive conditions. Common ceramic filler materials are alumina, silicon oxide and so on. Ceramic packing sheet has excellent wear and corrosion resistance and is suitable for chemical equipment under high temperature conditions.

4. Metal packing sheet: Metal packing sheet is generally made of steel structure mesh or aluminum fence sheet. It has good strength and pressure resistance and is suitable for various chemical equipment.

When selecting the filler sheet, it is also necessary to select the appropriate filler form and structure according to the specific reaction or separation process requirements. For example, for the adsorption process, a circular ring filler with a larger specific surface area can be selected to increase the contact area of the adsorbent; For the separation process, cluster sheet fillers with high volume voidage can be selected to increase fluid access.

In addition, it is also necessary to consider the factors such as the filling method, density and stacking method of the packing sheet. There are two kinds of loading methods: laminar flow loading and random loading, and the appropriate way is selected according to the specific requirements of the equipment. The density and packing method of packing sheet will also affect the effect of material transfer, so it is necessary to choose the appropriate packing sheet density and packing method.

In summary, the selection of the suitable packing sheet requires comprehensive consideration of physical characteristics, chemical characteristics and economy, and selection according to the specific process parameters and equipment requirements.
