Abstract
The utility model discloses a special shaped filter pipe for waste gas and water treatment, which belongs to the technical field of filter pipes. The special shaped filter pipe is adopted, and the cross section of the special shaped filter pipe is polygonal, and preferentially, the number of corners is greater than 5. Compared with the filter area of a common filter pipe, the filter area of the special shaped filter pipe disclosed by the utility model can be increased by at least 1.5 times to achieve the effects of reducing the flow resistance and prolonging the service life, and thereby, the special shaped filter pipe has the characteristics of high flow, long service life, small occupied area and simple structure. A lost mold core method is adopted to shape the special shaped filter pipe, so that the special shaped filter pipe has the characteristics of high finished product ratio, low production cost and short cycle.

Technical field
The utility model relates to screen pipe, waste gas and water-treatment technology field; Be particularly related to Separation of Solid and Liquid and gas solid separation technical field; Relate in particular to HTHP gas solid separation field; Be specifically related to a kind of special filter pipe that is used for waste gas and water treatment.
Background technology
For waste gas and water technology, its crucial core technology is the filter area of filter element, filtration yield and resistance to elevated temperatures, in order to improve filtration yield, various filters have constantly appearred, adopt multilayer, multitube increases filter area and filtering traffic, adopt the method for multilayer as patent CN91203176.X multiaperture-type filter, adopt the method for multitube as CN90207685.X novel meticulous water filter, these measures have all increased the complexity of device, be unfavorable for installing/dismounting and maintenance, single unit system exists volume to weigh greatly simultaneously, floor space is big, the cost of manufacture height, weak points such as comprehensive benefit difference are safeguarded inconvenience in commercial Application; To filter its operating temperature in order improving, to adopt ceramic material to do the screen pipe material, but pottery can not be in the big occasion use of temperature fluctuation, ceramic filter tube is frangible simultaneously, is not easy to install, and these have all limited the scope of application of ceramic filter tube.In order to overcome these deficiencies, adopt the special filter cross section to replace circular cross-section, this has increased filter area, has greatly improved filtering traffic, simplifies filter, save floor occupying area, reduce preparation cost, be fit to industry and use, maintenance cost is lower, use refractory metal and alloy thereof to improve serviceability temperature as the screen pipe material simultaneously, the characteristics that have recoil regeneration simultaneously increase the service life.
Summary of the invention
Increased the complexity of device at prior art, be unfavorable for installing/dismounting and maintenance, simultaneously single unit system exist volume big and weigh, floor space is big, cost of manufacture is high, comprehensive benefit difference and pottery can not be in the big occasion uses of temperature fluctuation, ceramic filter tube is frangible simultaneously, be not easy to deficiencies such as installation, the utility model provides a kind of special filter pipe that is used for waste gas and water treatment.
The cross sectional shape of described special filter pipe is a polygonal, and the number of preferred angle is greater than 5, and the number that optimum is selected the role is greater than 7, and more preferably the number at angle is greater than being 8～14.
The material of described special filter pipe can be stainless steel, titanium and titanium alloy, Monel series alloy or Inconel series alloy.
Preparation special filter pipe mould therefor inside configuration is the disappearance core rod, and the outside is a former, filling powder between former and the disappearance core rod.
Described core material can be bismuth tin antimony lead cadmium alloy, and wherein bi content is 40%-60%, and tin content is 40%-60%, and lead content 0-35%, antimony content are 0-35%, and cadmium content is 0-30%; Also can be cu-zn-al alloy, wherein zinc content is 86%-95%; Aluminium content is 1-8%; Copper content is 0%-6%.Former adopts polyurethane or polyvinyl chloride to form.
Described drawing method adopts the isostatic cool pressing compacting.
Described disappearance moulding/demoulding temperature is 70 ℃-400 ℃.
The beneficial effects of the utility model are:
(1) flow is big: because the more common screen pipe of unit volume filter area improves at least 1.5 times, therefore have bigger filtering traffic;
(2) renewable: owing to adopt the special filter pipe to constitute by metal material, the intensity height, just recoiling can, can remove the dirt that is deposited on the filter course surface by the method for recoil, can reuse;
(3) high temperature resistant: because special filter pipe material therefor all is a materials with high melting point, intensity height under the hot conditions, stable performance can reliably be used under hot conditions.
(4) life-span is long: owing to have reproducible characteristics, and intensity is higher, so the special filter pipe has long service life.
(5) moulding is simple: adopt the disappearance core rod, to being higher than disappearance mold materials temperature, the disappearance mould can melt outflow to blank heating in the compacting back, and operation is with short production cycle easily, the yield rate height, and the disappearance mold materials can be reused, and cost is low.
(6) applied range: can be used for fields such as pharmacy, environmental protection, food, metallurgy, chemical industry, be used for occasions such as gas purification, fluid purification, Separation of Solid and Liquid.
