Description

Plastic ring integrated block packing

Technical field:

The utility model relates to a plastic ring integrated block filler, which belongs to the field of tower filler accessories in the petrochemical industry.

Background technique:

At present, various tower packings widely used in the petrochemical industry can be divided into two categories: random packing (also known as granular packing) and structured packing; random packing and structured packing have their own advantages and disadvantages due to their different structures. Random packing is easy to fill, and can be removed, cleaned and reused after being blocked. However, due to the irregular angle between the packing plate and the cross-section of the tower in the tower, the packing resistance is large, the ventilation rate is small, and the gas flow rate is small. The mass transfer effect of the liquid is poor, and if there is sediment, it will easily cause the plugging of the packing. Structured packing is divided into two types: plate corrugated packing (made of various plates) and wire mesh packing (woven into a mesh with metal wires and processed into various shapes). The structured packing has a uniform structure and good gas-liquid mass transfer effect; especially plate The structured packing with sheets perpendicular to the cross-section of the tower has low resistance, large ventilation and is not easy to block, and is widely used in the petrochemical industry. However, since the connection points between the plates of this type of structured packing are mostly spot welded, and the packing plates are thin, the overall strength is not high. Once it is blocked and disassembled and cleaned, it will fall apart and deform, and cannot be reused.

Invention content:

The purpose of this utility model is to provide a multi-layer structure, each layer is composed of several polygonal rings, which can not only ensure the ventilation capacity of the filler and the effect of gas and liquid mass transfer, but also can be easily disassembled after blocking, and can be repeated. Used, one-time injection molded plastic ring integrated block packing.

The utility model realizes above-mentioned object through following technical scheme:

A plastic ring integrated block packing, which is composed of an upper integrated block, a middle integrated block and a lower integrated block. The hexagonal plastic rings of the block and the lower integrated block are arranged in a staggered state, and the intersections of the hexagonal plastic rings of the adjacent two-layer integrated blocks are naturally connected, and the rings of the hexagonal plastic rings of the interlayer integrated blocks The non-contact part is fixedly connected with a small cylinder.

The hexagonal plastic ring is a regular hexagon.

The utility model has the beneficial effects compared with the prior art in that:

The utility model adopts a multi-layer structure, and each layer is composed of several hexagonal plastic rings, and the hexagonal plastic rings are formed by one-time injection molding of an injection molding machine, and each layer of hexagonal rings is closely connected, and there are small The cylinder is fixedly connected, the packing has high strength, good stability, and can be reused. It not only ensures the ventilation capacity of the packing and the effect of gas and liquid mass transfer, but also solves the problem that the existing packing has low overall strength. After disassembly, it will fall apart and deform. The question of reuse.

Description of drawings:

The accompanying drawing is a structural schematic diagram of plastic ring integrated block packing.

In the figure: 1. Upper layer integrated block, 2. Middle layer integrated block, 3. Lower layer integrated block, 4. Intersection of ring pieces, 5. Small cylinder, 6. Hexagonal plastic ring.

Detailed ways:

The plastic ring integrated block packing is composed of an upper integrated block 1, a middle integrated block 2 and a lower integrated block 3. Each integrated block is composed of multiple hexagonal plastic rings 6 connected to each other. The hexagonal plastic rings 6 of the upper integrated block 1, the middle integrated block 2 and the lower integrated block 3 are arranged in a staggered state, and two adjacent layers are integrated. The intersecting parts 4 of the ring pieces of the hexagonal plastic ring 6 of the block are naturally connected, and the non-contact parts of the ring pieces of the hexagonal plastic ring 6 of the interlayer integrated block are fixedly connected by a small cylinder 5 (see the accompanying drawing), which is used to enhance the integration Overall strength of block packing. The height of the hexagonal plastic ring 6 is 2-4cm, the thickness is 0.2cm, and the height after being combined into the plastic ring integrated block filler is 6-12cm. The size of the hexagonal plastic ring 6 is determined according to the specific surface area of the packing, and the length and width of the plastic ring integrated block packing are determined according to the diameter of the packing tower and the size of the inlet hole.

When in use, put the plastic ring integrated block packing into the tower as the mass transfer and heat transfer element of the separation device in the tower. The hexagonal plastic ring 6 of the packing is perpendicular to the cross section of the tower and parallel to the direction of air flow and liquid flow. The packing resistance is small and the ventilation capacity is strong. Since the plastic ring integrated block packing adopts a multi-layer structure, and each layer is composed of several polygonal rings interlaced and connected with each other, the mass transfer effect of the packing is good. The filler is formed by injection molding at one time, has good stability, and can be disassembled and washed for repeated use after clogging. It is especially suitable for gas and liquid mass transfer in the fields of petroleum, chemical industry, pharmaceutical and environmental protection, as well as gas purification and cooling towers.
