　　Deere supplies regular packing, wire mesh, corrugated orifice plate, and corrugated regular models that can be customized

　　Metal wire mesh corrugated packing: It is an important milestone in the development of structured packing. This type of packing is composed of corrugated wire mesh sheets arranged in a staggered manner, with an inclination angle of 30 ° or 45 °. Adjacent corrugated sheets have opposite directions. When filling inside the tower, the upper and lower plates of packing are stacked in a 90 ° staggered manner. It has the advantages of high efficiency, pressure reduction, and high flux. The products include BX and CY types, which are commonly used in vacuum distillation, atmospheric distillation, and absorption processes for difficult to separate and thermosensitive substances.

　　The tower diameter range for processing metal regular corrugated packing is over 150mm to 12000mm. It is a filling material arranged in a uniform geometric pattern and neatly stacked inside the tower. It specifies the gas-liquid flow path, improves the phenomena of channel flow and wall flow, reduces pressure drop, and provides more specific surface area, achieving higher mass and heat transfer effects in the same volume Due to the uniformity, regularity, and symmetry of the structure, when the specific surface area is the same as that of bulk packing, the porosity of metal orifice plate corrugated packing is larger, and it has a larger flux. Its comprehensive processing capacity is much larger than that of plate tower and bulk packing tower. Therefore, various universal structured packing represented by metal orifice plate corrugated packing are applied in industry. Due to its advantages of pressure reduction, high flux, and high separation efficiency, regular packing has been widely used in many towers in the fields of fine chemicals, spice industry, oil refining, fertilizers, petrochemicals, and more.

　　Deere Packing provides guidance and installation services for corrugated plate packing in refining and chemical companies

　　Our company (Dier Chemical Packing Co., Ltd., Pingxiang City, Jiangxi Province) provided on-site guidance to a customer of a refining company on the installation of stainless steel corrugated plate regular packing (available in two models, 2.0A and 1.5A, with a total quantity of 230 cubic meters, made of 316L material). The customer used it for the maintenance and replacement of the pressure reducing tower packing. Our company sent personnel to the site to guide and arrange the plating, lifting, and tower entry according to the on-site replacement sequence, in order to gain more maintenance time for the customer.

　　The installation method of regular packing is as follows:

　　Before installing each piece of packing, carefully disassemble it and arrange it in line according to its assembly drawing box number. Find the required number and number of blocks for each tray, and assemble the entire tray on a spacious and flat ground. When installing the packing, the installation personnel should not stand in the middle of the tower section, as this can easily form a "pot bottom" phenomenon with high, medium, and low areas around. Each packing assembly requires the use of a skateboard for installation. Due to the non roundness of the tower and other reasons, it is sometimes necessary to add or remove pieces of packing as appropriate to make the packing suitable for the tower body. Installing the packing too tightly can cause deformation of the packing sheet, increase the total height of the packing, make the upper end face uneven, and decrease the efficiency flux. Similarly, if the packing is installed too loosely, it can lead to uneven gas-liquid distribution and a decrease in separation efficiency. Usually, the installation starts from one end and ends at the other end. The direction of the corrugated sheet of the disk packing is at a 45 ℃ angle to the direction of the support plate, and the corrugated sheets of adjacent disks are at a 90 ℃ angle. The starting position for installing each tray of packing is every four trays of packing per cycle. By rotating the packing tray clockwise (or counterclockwise), the horizontal error of the upper end face of the packing can be reduced. Remove the corners of the packing after each installation is completed. Corrugated plate regular packing is an efficient regular packing that is specifically produced according to the requirements of different tower diameters, steam speeds, and spray densities of users. Different tower diameters have different block sizes allocated, and are assembled according to the assembly drawing and placed in the corresponding position until the design height is reached.

　　Dier Chemical Packing Co., Ltd. was established in 2004 in Pingxiang City, Jiangxi Province. It is engaged in the development and production of green separation technology and equipment, including complete process package technology and various tower internals equipment technology and products. It has multiple domestic and foreign invention patents, and its products include high-efficiency packing materials and high-performance tower plates and tower internals made of various materials such as metal, ceramic, plastic, etc., with a total of 18 series and more than 100 varieties.
