Abstract
An axial rotational flow of a cyclone dust collector of the utility model adopts the methods of casting or injection molding by metal or plastics to process an integral rotational flow unit which is combined by a plurality of rotational flows. An external cylindrical unit positioning structure is adopted between the tailstock and the cylindrical body of the rotational flow unit, and the tailstock of the unit is equipped with a positioning table. The rotational flow can be made with minor diameters or supermini diameters, and thus, the rotational flow is not easy to be blocked by the concentrated dusty gas to assure the stable work. The utility model has the advantages of convenient processing, sealing, installation, maintenance, and can save a great number of steel plates, and thus, the utility model can be used for the purification devices of the large-sized stove blowers in iron and steel enterprises, electricity power industry, etc.
Description
The utility model relates to eddy flow stream of a kind of dust arrester, particularly axial-flow type cyclone dust collectors.
At present domestic each big steel mill all adopts the inventor to be assembled by some single axial-flow type eddy flow in pure " axial-flow type cyclone dust collectors " this deduster that the people such as allows to succeed in developing in 1979.Each axial-flow type eddy flow is to be made of: cylindrical shell, baffle, tailstock three parts.US Patent No 3915679 open " whirlwind air cleaning unit " structures are basic with last identical, and their existing weak points are:
1. eddy flow is single making, and assembly unit then, the especially barrel diameter when eddy flow dwindle the back, when not changing axial wind speed, and single eddy flow processing air quantity will reduce.To handle big air quantity in order reaching, must to adopt the sub-assembly unit of eddy flow of big quantity, give produce, assembling, maintenance bring very big difficulty, make it to be difficult for making eddy flow (as the D=20 millimeter) of minor diameter or extra small diameter thus limited the raising of efficiency of dust collection.
2 for the cylindrical shell and the even slit between the tailstock that guarantee eddy flow, on tailstock, be provided with 3 to 4 positioning tables, these positioning tables and be and cylinder inboard wall realizes that thereby the location gas-flow resistance increases, influence tailstock eddy flow on every side, when the dusty gas that concentrates passes through the slit, easily blocked, when dwindling barrel diameter and improve efficiency of dust collection, this problem performance is more outstanding.
The purpose of this utility model: provide a kind of employing tube outer cell location for solving above-mentioned two problems, and by a plurality of eddy flow sub-portfolios eddy flow subelement in aggregates.
Main points of the present utility model: be method with metal or plastics, employing casting or injection mo(u)lding, be processed into by a plurality of eddy flow sub-portfolios eddy flow subelement in aggregates, the outer cell location structure of tube has been adopted in the tailstock of eddy flow subelement and the location between the cylindrical shell, on the unit tailstock, be provided with positioning table, be provided with the ladder limiting stand that has microsize to change with cylinder internal diameter in addition in the cylindrical shell, limit the tram of baffle.
Advantage of the present utility model:
1. owing to be combined into an integral cyclone subelement, can make each eddy flow in the unit make axial-flow type eddy flow of minor diameter or extra small diameter (and even diameter is less than 10 millimeters).When being assembled into the axial-flow type deduster, can under the condition that does not increase resistance, realize that the processing air quantity reaches tens myriametres
3/ time is 18～20 milligrams/meter at dust content
3The time.Its efficiency of dust collection can reach more than 90%.
2. because of the interior location structure with each cylindrical shell and tailstock changes integral cyclone subelement outside fix structure into, so after barrel diameter dwindled, the dusty gas that is difficult for being concentrated blocked.Thereby working stability.
3. be convenient to processing, can once can make some, a certain size one group of eddy flow subelement arbitrarily according to actual needs, improved working (machining) efficiency, guarantee the dimensional accuracy between the cylindrical shell.
4. be convenient to install, when being assembled into large-scale deduster, saved a large amount of steel plates, and processing capacity.Improve tens times of installation effectiveness, be convenient to very much sealing, be easy to management, maintenance.
5. can be widely used on the cleaning equipment of iron and steel enterprise, electric power industry, large centrifugal or axial-flow type blast furnace blower.
Further specify below in conjunction with accompanying drawing.
Fig. 1, the 2nd, the structure chart of this built-up shaft streaming eddy flow subelement.With reference to Fig. 1,2:
It is made of baffle (2), cylindrical shell (3), tailstock (4), cylinder internal diameter can be 10～100 millimeters, be provided with at the inwall of cylindrical shell (3) and adopt tight fit to pack between a small ladder platform (1), baffle (2) and the cylindrical shell (3), by small ladder platform (1) location.On tailstock (4), be provided with four positioning tables (5), cylindrical shell (3) outer wall and four positioning tables (5) and interfix, guaranteed tubular axis and the coaxial and cylindrical shell of tailstock axis and the distance between the tailstock.Thereby cylindrical shell (3), tailstock (4), baffle (2) three parts have constituted a built-up shaft streaming eddy flow subelement.
With several eddy flow subelement assembly units, the axial-flow type cyclone dust collectors have been constituted again.A processing air quantity of preparing at present in the Anshan iron and steel plant power plant is 360000 meters
3The axial blower in/time is implemented on probation.It selects cylinder internal diameter D=50 millimeter, 18 unit that the eddy flow sub-portfolio becomes, the large-scale deduster that adopts 840 unit splicings to become for use.If single processing and assembling: then need the processing and the assembly working amount of 18 * 840=15220 eddy flow, foregoing 2 foot phenomenons not just can occur.
Claims (2)
