Description
Technical Field
The invention relates to a shell pass division partition plate of a photo-thermal heat exchanger for enhancing heat insulation, and belongs to the technical field of heat exchangers.
Background
The photothermal heat exchanger is mainly applied to the field of tower type or groove type photothermal steam generation system heat exchangers, heat transfer of the upper side and the lower side of the split-ranging partition plate is reduced by arranging the reinforced heat insulation layer, and then the heat exchange efficiency of the heat exchanger is improved.
A pass partition plate is arranged in the shell side double-pass heat exchanger to divide the shell side into an upper space and a lower space, and after the operating medium enters the shell from the upper space to exchange heat with the medium in the heat exchange tube, the operating medium enters the lower space to continuously exchange heat to form a double-pass. However, the double-flow-path heat exchanger has a defect that: because the temperature of the fluid on the upper side and the lower side of the pass partition plate is different, energy can be directly transmitted to the low-temperature side through the pass partition plate, and the heat exchange efficiency of the heat exchanger can be reduced, and the operation efficiency of the whole heat exchange system can be further influenced.
Currently, the shell-side pass divider is typically a single layer of steel plate, as shown in fig. 1, through which energy is transferred directly. For a photothermal steam generation system heat exchanger, the shell side operating medium is molten salt (60 wt% NaNO)3+40wt％KNO3) The temperature difference between the inlet and the outlet of the fused salt is large, so that the temperature difference between the upper side and the lower side of the split-range partition plate can reach dozens of degrees centigrade, and a large amount of energy waste is brought by the high temperature difference.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the fluid temperature at the two sides of the pass partition board is different, and the energy is directly transmitted to the low-temperature side through the pass partition board, so that the heat exchange efficiency of the heat exchanger is reduced.
In order to solve the technical problems, the invention adopts the following technical scheme:
the utility model provides an adiabatic light and heat exchanger shell side journey baffle of reinforcing which characterized in that, is equipped with a cushion respectively between the both ends of going up baffle, lower baffle including parallel arrangement's last baffle and lower baffle, goes up and forms middle air bed between baffle, lower baffle and the both sides cushion. The energy is natural convection heat transfer when passing through the air layer, the heat transfer resistance is far greater than that of the partition plate, and the effect of reducing the heat transfer can be effectively realized.
The pass partition plate is suitable for a heat exchanger with a shell side heat exchange medium of molten salt.
The pass partition plate can effectively increase the heat transfer resistance of the pass partition plate, reduce the heat exchange of the upper side and the lower side of the pass partition plate and improve the heat exchange efficiency of the heat exchanger.
Compared with the prior art, the invention has the beneficial effects that:
1. the two pass partition plates and the air heat insulation layer formed between the two pass partition plates form a heat insulation structure so as to reduce heat transfer of the upper side and the lower side of each pass partition plate.
2. Under the condition of the same medium inlet and outlet parameters, the heat exchanger with the novel enhanced heat insulation type pass partition plate can effectively improve the heat exchange efficiency and reduce the heat exchange area by about 5 percent.
