Abstract
The utility model discloses a novel fixed tube-sheet heat exchanger of a tube-street structure. The novel fixed tube-sheet heat exchanger is characterized in comprising a tube box, a shell and a tube sheet; wherein a tube is welded on the tube sheet. The tube sheet and a tube are welded and fixed in the shell; and a lining flange is welded on the tube box. According to the novel fixed tube-sheet heat exchanger of the tube-sheet structure, the flange is welded outside the shell, so that no influence is exerted on a seal surface when the tube is welded with the tube sheet, in the way, the leakage problem is solved; and at the same time, the thickness of the tube sheet is decreased, and the cost is saved.
Description
Technical field
The utility model relates to a kind of technical field of heat exchangers, the fixed tube-sheet exchanger of a kind of novel tube plate structure of saying so more specifically.
Background technology
At present, fixed tube-sheet exchanger is simple in structure, low cost of manufacture, tube side convenience for washing; Tube side can be divided into multipass, and shell side also can be divided into round trip, and specification limit is wide; So extensive use on engineering, but in use find, when adopting Stainless Steel Tubular Plates; The stainless steel tube period of the day from 11 p.m. to 1 a.m, two ends adopt welding method that pipe is fixed on the heat exchanger on the tube sheet, and the junction of bobbin carriage and housing is prone to leak; The problem that time one length can cause the thermal efficiency to descend for the thickness of anti-heads to pipe and tube sheet increases, just can produce the problem that material cost rises simultaneously.
Summary of the invention
The technical problem that the utility model will solve: for shortcoming and the deficiency that overcomes prior art, the utility model is a kind of fixed tube-sheet exchanger that solves leakage, saving cost, improves the novel tube plate structure of the thermal efficiency.
The technical scheme of the utility model is: a kind of fixed tube-sheet exchanger of novel tube plate structure, it is characterized in that it comprises bobbin carriage, housing and tube sheet, and be welded with pipe on the said tube sheet.
Described tube sheet and pipe are weldingly fixed on the inside of housing, are welded with the lining flange on the said bobbin carriage.
Adopted the fixed tube-sheet exchanger of the novel tube plate structure of the utility model, owing to the outside that is welded on flange housing, when pipe and tube sheet welding; Can not influence sealing surface; Solve leakage problem, reduced the thickness of tube sheet simultaneously, played the effect that provides cost savings.
Description of drawings
The utility model is described further with implementing below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of the utility model.
Among the figure: the 1-bobbin carriage, the 2-housing, the 3-tube sheet, the 4-pipe, 5-serves as a contrast flange.
The specific embodiment
The fixed tube-sheet exchanger of a kind of novel tube plate structure as depicted in figs. 1 and 2 is characterized in that, it comprises bobbin carriage 1, housing 2 and tube sheet 3; Be welded with pipe 4 on the said tube sheet 3, described tube sheet 3 and pipe 4 are weldingly fixed on the inside of housing 2, are welded with lining flange 5 on the said bobbin carriage 1; Be welded on the inside of housing 2 to the part of pipe 4 welding, be connected with lining flange 5 with bobbin carriage 1, the outer set that this flange is welded on housing 2 is integral; When pipe 4 welds with tube sheet 3, can not influence sealing surface, thereby solve leakage problem, simultaneously; Reduce the thickness of tube sheet 3, provided cost savings spending.
