Abstract
Novel pipe-shell type double-shell-pass spiral baffle plate heat exchanger, comprise bobbin carriage, tube sheet, housing, heat exchanger tube, annular pass partition, branch journey inner core, anti-short circuit inside spin deflection plate, anti-short circuit external spiral deflection plate, pull bar, distance sink tube, it is characterized in that also comprising sealing drum and the interior sealing drum of housing in the adapter, sealing drum left end and tube sheet are tightly connected in the described housing, right-hand member and annular pass partition are tightly connected, open a hole on the sealing drum in the described housing below taking over, sealing drum internal diameter in size approximates and takes over, and with described adapter in sealing drum one end be tightly connected.More reasonable structure of the present invention is compacter, the branch journey hermetically-sealed construction that sealing drum, tube sheet, annular pass partition, the formation of branch journey inner core are connected as a single entity in sealing drum, the housing in taking over, solved leakage problem between the double-shell of prior art, made pipe-shell type double-shell-pass spiral baffle plate heat exchanger can reach the technological requirement of expection and can significantly improve heat exchange efficiency.
Description
(1) technical field
The present invention is applied to the pipe-shell type double-shell-pass spiral baffle plate tubular heat exchanger in the industry technological processes such as oil, chemical industry, generating, metallurgy.
(2) background technology
Bivalve journey structure such as Fig. 1 of general pipe-shell type double-shell-pass spiral baffle plate heat exchanger show: annular pass partition (8) is positioned at the shell side import and export to be taken in the middle of (5), and the branch journey structure of being made up of a minute journey inner core (10), annular pass partition (8), elastic packing steel disc (6) and bolt (3) is divided into first shell side and second shell side with housing.Annular pass partition (8) excircle cooperates with housing (7) inwall, takes to be fixed on the recline mode of housing (7) inwall of elastic packing steel disc (6) on annular pass partition (8) edge by bolt (3).The journey hermetically-sealed construction inevitably produced certain leakage rate between housing (7) inwall and annular pass partition (8) excircle in this minute, had caused the short circuit between double-shell to be leaked, thereby had weakened the heat exchange efficiency of heat exchanger.
(3) summary of the invention
In view of the problem that above-mentioned pipe-shell type double-shell-pass spiral baffle plate heat exchanger exists, the present invention is intended to disclose the more rational novel pipe-shell type double-shell-pass spiral baffle plate heat exchanger of a kind of structure, so that solve leakage problem between double-shell.
Technical solution of the present invention is achieved in that
Novel pipe-shell type double-shell-pass spiral baffle plate heat exchanger, comprise bobbin carriage, tube sheet, housing, heat exchanger tube, annular pass partition, branch journey inner core, anti-short circuit inside spin deflection plate, anti-short circuit external spiral deflection plate, pull bar, distance sink tube, it is characterized in that also comprising sealing drum and the interior sealing drum of housing in the adapter, sealing drum left end and tube sheet are tightly connected in the described housing, right-hand member and annular pass partition are tightly connected, open a hole on the sealing drum in the described housing below taking over, sealing drum internal diameter in size approximates and takes over, and with described adapter in sealing drum one end be tightly connected.
Compared with prior art, the invention has the beneficial effects as follows conspicuous:
The technical solutions according to the invention more reasonable structure is compacter, the branch journey hermetically-sealed construction that sealing drum, tube sheet, annular pass partition, the formation of branch journey inner core are connected as a single entity in sealing drum, the housing in taking over, solved leakage problem between the double-shell that prior art causes because of leakage region between inner walls and annular pass partition excircle, guarantee that whole media flow into the first journey inner core from entrance sleeve and flow into second journey again, the final discharge connection that all flows into, the technological requirement that makes pipe-shell type double-shell-pass spiral baffle plate heat exchanger can reach expection also can significantly improve heat exchange efficiency.

(5) specific embodiment
Technical scheme of the present invention is provided by following embodiment: at first with annular pass partition (8) and branch journey inner core (10) left end seal weld; Pull bar (14) that again will branch journey inner core (10) interior location, distance sink tube (4), nut (13), interior short circuit-proof spiral baffle plate (12), heat exchanger tube (9) assemble with tube sheet (2); Be inserted in above-mentioned parts with annular pass partition (8) that has been connected as a single entity and branch journey inner cylindrical (10); Pull bar (14) that again will branch journey inner core (10) external position, distance sink tube (4), nut (13), outer short circuit-proof spiral baffle plate (12), heat exchanger tube (9) assemble with tube sheet (2) and annular pass partition (8); The place's perforate of connecting pipe of shell (5) below will be positioned at again on the sealing drum in the housing (3), sealing drum (6) internal diameter in size approximates and takes over, then put above-mentioned parts, seal weld is connected with annular pass partition (8) with tube sheet (2) respectively with sealing drum in the housing (3) two ends again; Again housing (7) is put above-mentioned parts and assemble firm with two ends tube sheet (2), left pipe box (1), right pipe box (15); Again sealing drum (6) lower end in the adapter in the connecting pipe of shell (5) is connected with sealing drum (3) perforate periphery seal weld in the housing.
Claims (1)
1, novel pipe-shell type double-shell-pass spiral baffle plate heat exchanger, comprise bobbin carriage, tube sheet, housing, heat exchanger tube, the annular pass partition, divide the journey inner core, anti-short circuit inside spin deflection plate, anti-short circuit external spiral deflection plate, pull bar, distance sink tube, it is characterized in that also comprising sealing drum (6) and the interior sealing drum (3) of housing in the adapter, sealing drum (3) left end and tube sheet (2) are tightly connected in the described housing, right-hand member and annular pass partition (8) are tightly connected, in the described housing of taking over (5) below, open a hole on the sealing drum (3), sealing drum (6) internal diameter in size approximates and takes over, and with described adapter in sealing drum (6) one ends be tightly connected.
