Abstract
The utility model relates to a rectangular pipe box with a new structure for an air cooling device. A box body which is in a rectangular shape comprises a pipe plate, a wire wall plate, a top plate, a bottom plate and cover plates, wherein both ends of the box body are connected with rectangular flanges; the rectangular flanges and the cover plates of both ends are firmly connected by screw bolts, screw nuts and shims; screw holes on the wire block plate are blocked by screw blocks and shims. The utility model integrates the advantages of a wire block type pipe box and a detachable cover plate type pipe box into a whole. The utility model has the characteristics of strong pressure-bearing ability, convenient overhauling, material saving, etc. The rectangular pipe box with new structure for an air cooling device can operate safely under the condition of high pressure, and can easily discharge the scale deposit of a pipe bundle.
Description
The utility model relates to a kind of square type bobbin carriage that is used on the Air-cooled Heat Exchanger, is applicable to industry Air-cooled Heat Exchanger such as oil refining, chemical industry, electric power, metallurgy.
At present, the bobbin carriage of using on China's Air-cooled Heat Exchanger has three kinds of the board-like and detachable cap types of removable cover, threaded plug type, set tubular type, and the pressure limit of its adaptation is as follows:
| The bobbin carriage pattern | Permissible working pressure (MPa) |
| Board-like and the detachable cap type threaded plug type set of removable cover tubular type | ≤6.4 ≤20 ≤35 |
The scope of application of various bobbin carriages and characteristics:
1, the board-like and detachable cap type bobbin carriage of removable cover:
Be applicable to that pressure is lower, and the occasion of the easy fouling of medium.Have tube-to-tube sheet connection and be connected to welding, the characteristics of bobbin carriage and pipe content easy cleaning; Shortcoming is that the potted line of bobbin carriage is oversize, and the bobbin carriage sealing is easily leaked, and high slightly tube sheet, the cover plate of can causing of pressure is too thick, and metal consumption is too many, and manufacturing cost is excessive.
2, threaded plug type bobbin carriage:
Be applicable to that pressure medium is higher, and the occasion of slight fouling is arranged.Tube-to-tube sheet connection is connected to expanded joint, also can adopt seal weld sometimes, equipment is required high.Advantage is that the maintenance maintenance is convenient, and handling ease is simple in structure; Shortcoming is that labor content is big, and leakage point is many, and the cleaning in the bobbin carriage is difficulty relatively.
3, set tubular type bobbin carriage;
Be applicable to that pressure is higher, the clean less scaling occasion of medium in the pipe.Tube-to-tube sheet connection is connected to welding, but welding condition is poor, sealing property is better, and metal consumption is minimum; Shortcoming is the maintenance difficulty, and is not capable of washing in the bobbin carriage, is not suitable for the many situations of the row's of pipe number.
The air cooler standard A PI661 of external air cooler standard such as American Petroleum Institute (API), JPI JPI7R-51 also has only the bobbin carriage of the board-like and detachable cap type of removable cover, threaded plug type, three kinds of patterns of set tubular type on the iso standard of the U.S..
The purpose of this utility model is to overcome that the board-like bobbin carriage of removable cover cover plate when pressure is higher is too thick, potted line is oversize, easy leakage, the weak point that the fouling of threaded plug type bobbin carriage is difficult to discharge, provide a kind of both can safe operation under the higher situation of pressure, easily discharge the bobbin carriage fouling again, save the rectangular pipe box of steel again.
The purpose of this utility model is achieved in that
A kind of new construction air cooler rectangular pipe box.Its casing comprises tube sheet, plug plate, top, base plate and cover plate, and is rectangular, it is characterized in that: described tank ends is connected with rectangular flange, and this rectangular flange becomes to be fastenedly connected with nut, nut, pad with two end cover plate; Each blocks screw on the described plug plate with plug and pad.
Described casing is made with carbon steel, steel alloy.
The utility model has following actively useful effect:
During the tube leak of tube bank, take off plug on the square type bobbin carriage and the pipe that leaks is blocked to continue to produce.When pipe or bobbin carriage obstruction, the cover plate of end face can be unloaded, from pipe plug opening cleaning pipe, clear up bobbin carriage, fix a breakdown rapidly maintenance, easy to maintenance from cover plate.
The utility model integrates the advantage of threaded plug type bobbin carriage and the board-like bobbin carriage of removable cover, and it is strong to have a bearing capacity, and maintenance is convenient, saves characteristics such as material.
It is higher that the utility model is suitable for pressure, and medium easily stops up in the pipe, needs the Air-cooled Heat Exchanger of thoroughly cleaning during maintenance.
Now in conjunction with the accompanying drawings with preferred embodiment:
