Abstract
The utility model discloses a shell pipe heat exchanger with turbulent spirals, comprising a tank-shaped shell body, a head, a heat exchange coil pipe, and a pipe plate, and is characterized in that supporting steel wires and turbulent spiral steel wires which are arranged around the supporting steel wires are arranged in the heat exchange coil pipe; the supporting steel wires and the turbulent spiral steel wires are connected for fixing by a steel wire fixing column. Meanwhile, 2 or 3 channels of deflecting plates are arranged in the shell pipe. Heat transfer coefficient can be increased by 20-200%. Total heat exchange quantity can be increased. The utility model is used for a hot water supply system. The volume of the heat exchanger can be reduced. The space occupation can be saved.
Description
The utility model belongs to the heat-exchange apparatus that general heat-exchange apparatus, particularly heat exchange medium directly do not contact.
At present, in the hot water supply system of industry and civil buildings, shell and tube exchanger has general application.Shell and tube exchanger is that heat exchange coil is set in tank-like shell, is thermal medium with steam or high-temperature water, flows through in heat exchange coil, and heat is transferred to medium in the housing from the tube wall of heat exchange coil, as heating cold water, realizes heat exchange.In order to improve heat exchange efficiency, often adopt the quantity of increase heat exchange coil or the measure of length, to increase heat exchange area.Because the loop length of heat exchange coil is subjected to the restriction of vome of shell size, so the growth of heat exchange efficiency is limited.
The purpose of this utility model is that the turbulent flow helical is set in heat exchange coil, can improve velocity of medium in the pipe, and can cause flowing of thermal medium to be turbulent flow, to quicken the heat transfer process of thermal medium, further improves heat exchange efficiency.
The shell and tube exchanger that has the turbulent flow helical of the present utility model, form by tank-like shell, end socket, heat exchange coil, tube sheet, it is characterized in that, in heat exchange coil, be provided with supporting steel wire and turbulent flow helical steel wire, turbulent flow helical steel wire is fixed-type around supporting steel wire, connect with the fixation with steel wire post, be the helical type around supporting steel wire to keep turbulent flow helical steel wire.
In housing, be vertically arranged with 2～3 road deflection plates.
Turbulent flow helical steel wire also can be wrapped on the heat exchange coil outer wall.
The shell and tube exchanger that has the turbulent flow helical of the present utility model, have the following advantages: when thermal medium flows in heat exchange coil, no longer include laminar boundary layer stably, but rapid turbulent flow, strengthened the heat transfer of thermal medium and coil pipe tube wall, make heat transfer coefficient increase 20～200%, under the condition that does not increase heat exchange coil length, can increase total heat exchange amount; The setting of deflection plate can make medium moving at housing invagination linear flow, increases medium heat transfer flow process, increases the stirring of washing away to the pipe outer wall.The saving steel are played in these measures, do not increase vome of shell, do not enlarge economic benefits such as taking up an area of the space.
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the front view that has the shell and tube exchanger of turbulent flow helical.
Fig. 2 is the heat exchange coil structural map that has the shell and tube exchanger of turbulent flow helical.
Fig. 3 is the A-A profile of Fig. 2.
Fig. 4 is that turbulent flow helical steel wire is wrapped in the structure chart on the heat exchange coil outer wall.
As seen from the figure, the shell and tube exchanger that has the turbulent flow helical, by housing 1, end socket 2, heat exchange coil 3, tube sheet 4 is formed, heat exchange coil is the many rows copper pipe that be arranged in parallel, caliber Φ 25mm, two ends are fixed on the tube sheet, it is characterized in that, be provided with the supporting steel wire 5 of Φ 5mm and the turbulent flow helical steel wire 6 of Φ 1～2mm in heat exchange coil, helical steel wire external diameter is a coil pipe caliber 3/5, Φ 15mm, the two ends of supporting steel wire 5 are fixed on the cross fixation with steel wire post 7, between turbulent flow helical steel wire and the supporting steel wire, 3～5 pitch in every interval are established a short fixation with steel wire post 8 and are connected and fixed.2 road deflection plates 9 longitudinally vertically are set in housing, reserve the space between one of them deflection plate upper end and housing, reserve the space between another deflection plate lower end and housing, impel medium to change flow direction, further improve heat exchange efficiency.When turbulent flow helical steel wire 6 is wrapped in the outer wall of heat exchange coil, has the performance that causes turbulent flow equally.
