Abstract

The utility model provides a ceramic low ring packing, belonging to tower internals technology packed in the industrial tower, comprising a ring-shaped body (1) and a supporting rib (2) in the ring-shaped body. The utility model is characterized in that the supporting rib (2) is Y shaped; the ring-shaped body (1) is integrated with the supporting rib (2). Compared with other tower internals, the ceramic low ring packing has the advantages that: (1) the operation flexibility is great. Under the load of 30% to 200% of the tower design, the production need can be guaranteed. In particular condition, after the technical improvement of the outside of the tower, the normal products can be produced under the load of 10% to 300%; (2) the mass transfer efficiency is high. Testified by experiment, the mass transfer efficiency of the packing is 1.3 times of the mass transfer efficiency of the high efficient mental packing Mellapack; (3) the pressure drop is low. The pressure loss that the airflow in the tower cross the ceramic low ring packing is low;(4) compared with alloy steel high efficient packing, the cost of the ceramic low ring packing is lower, and corrosion resistance is stronger.

Description

The low ring filler of pottery

Technical field

The utility model belongs to the tower internals technology of filling in the industrial tower, mainly proposes the low ring filler of a kind of pottery, is widely used in refining oil, distillation, absorption, the separation process in petroleum chemical engineering fields such as chemical fertilizer, sulfuric acid, metallurgy.

Background technology

Packed tower is one of gas-liquid mass transfer (contact) equipment the most frequently used in the petro chemical industry, and filler is set in tower, gas, liquid two is on good terms reaches the needed contact condition of good mass-transfer.Packed tower to the basic demand of used filler in it is: 1, mass-transfer efficiency height.Advance the fully contact in tower of tower material, the heavy component in gas, the liquid two-phase is moved to lower tower section, light component moves to upper tower section, forms stable weight component concentration gradient, also forms pressure, temperature, the gradient distribution from bottom to top of full tower naturally.2, operating flexibility is big.The general operating flexibility that requires is a minimum load and the ratio of the ratio of normal duty and maximum load and normal duty is 50%-150%.3, the gas phase pressure that passes packed tower falls for a short time, can reduce the power consumption of carrying logistics.The low ring filler bed pressure drop of pottery is littler than other ceramic packing pressure drop, helps energy-conservation.Used aborning packed tower, what have is in the heavy corrosion operating mode, and the needs that have are handled foaming substance.At present, the intensity of the ceramic packing Raschig ring that industrial circle adopts, saddle ring, Pall ring, net ring etc. is lower, and specific area is little, operating flexibility is little, pressure falls greatly, mass-transfer efficiency is lower.

Summary of the invention

The purpose of this utility model is to propose the low ring filler of a kind of pottery, its intensity is enhanced and makes it have that specific area is big, operating flexibility big, characteristics less and that mass-transfer efficiency is high fall in pressure by its structural design.

Low its technical pattern of ring filler of the pottery that the utility model proposes is: be made of the brace rod in annular solid and the annular solid, brace rod is a Y shape, and annular solid and brace rod are structure as a whole.

Has hole and hole circumference uniform distribution on the wall of annular solid along annular solid.

The height of annular solid is 1: 2 with the ratio of external diameter.

The low ring filler of the pottery that the utility model proposes is compared with existing diffusing heap ceramic packing, and its characteristics are:

(1) the Y shape brace rod that is provided with in the annular solid has strengthened the intensity of filler, thereby has improved service life, increases its specific area, has improved mass-transfer efficiency.

(2) increased the flux of packing layer along the hole of annular solid circumference uniform distribution, bed pressure drop is reduced.

(3) height of annular solid is 1: 2 with the ratio of external diameter, and the filler after making it pack in tower has preferably regularity than general random packing, and promptly gas, liquid runner are stable, easily form stable gas, liquid concentration gradient, thereby improve mass-transfer efficiency, make product quality better.

The low ring filler of the pottery that the utility model proposes and other tower internals relatively have the following advantages:

(1) operating flexibility is big.When tower design load 30%-200%, can guarantee production requirement.In particular cases, transform, can under the 10%-300% load, go out normal product through the tower exterior technology.

(2) mass-transfer efficiency height.Through measuring, be 1.3 times of mass-transfer efficiency of efficient metal filler Mellapack.

(3) pressure drop is little.The pressure loss that the interior air-flow of tower passes through the low ring filler of pottery is little.

(4) compare with steel alloy material high efficiency packing, the low ring of pottery cost is low, and corrosion resistance is higher.

The low ring filler of the pottery that the utility model proposes can be installed maintenance very easily, be widely used in the rectifying, absorption, the separation process that need number of theoretical plate a lot of, also can be used for the occasion of seriously corroded and be used for foaming material, the low ring filler of pottery there is the froth breaking effect, thereby can reduce tower height, improve the product earning rate, the quality of product is improved, also can play energy-conservation effect for old tower.

The specific embodiment

The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model structure:

As shown in Figure 1 and Figure 2 and with reference to Fig. 3, low its main body of ring filler of the pottery that the utility model proposes is an annular solid 1, has Y shape brace rod 2 in the annular solid 1, brace rod and annular solid are structure as a whole, the annular solid of this filler and brace rod are to be material with silica, alundum (Al, and form through the porcelain mud of deferrization is refining.Wherein, annular solid and brace rod identical material, global formation.The ratio of the height of annular solid and external diameter is designed to 1: 2, promptly gas, liquid runner are stable can to make filler after packing in the tower have preferably regularity than general random packing, easily form stable gas, liquid concentration gradient, thereby improve mass-transfer efficiency, make product quality better.Have three holes 3 and hole circumference uniform distribution on the wall of annular solid 1, increased the flux of packing layer, bed pressure drop is reduced along annular solid 1.

Claims (3)

1, the low ring filler of a kind of pottery, it is characterized in that: be made of the brace rod (2) in annular solid (1) and the annular solid, brace rod (2) is a Y shape, annular solid (1) is structure as a whole with brace rod (2).
