Flow channel selection of spiral plate heat exchanger
Spiral plate heat exchanger channel selection: for the cold and hot fluids for heat exchange, first of all, it is necessary to pay attention to the unclean and easy to scale fluid suitable to go through the tube, because the tube cleaning is more convenient; In this case, the corrosive fluid is suitable for pipe passage, after which the tube bundle and shell can be avoided from being corroded at the same time; The fluid with high pressure should go through the pipe to avoid the shell to bear the pressure.
For the selection of the channel of spiral plate heat exchanger, the saturated steam should go through the shell path, because the heat transfer coefficient of steam condensation has nothing to do with the flow rate, and the condensate is easy to discharge. If the temperature difference between the two fluids is large, it is necessary to pay attention to the use of fixed tube spiral plate heat exchanger equipment, it is appropriate to make the heat transfer coefficient of the fluid through the shell, in order to reduce the thermal stress.
What are the functions of spiral plate heat exchanger equipment:
Spiral plate heat exchanger equipment although the form is not the same, but in general the role of the heat exchanger is no more than the following three, or a combination of the three. First of all, it is necessary to pay attention to the case of definite heat exchange, that is, to exchange a certain amount of heat in a certain amount of time between certain fluids.
The second step is to recover heat for the purpose of the situation, at this time the main need to consider its economy, that is, the benefits of recovery and the relationship between investment expenditure, so as to select the economic equipment; The third is for safety, that is, to prevent the temperature rise caused by pressure rise caused by some equipment damage, some coolers fall into this category. Spiral plate heat exchanger caused by different functions, their design, selection and operation are also different.
Murphy spiral plate heat exchanger is a common heat exchanger in the heating system. Its operation directly affects the external heating quality. Murphy experts analyzed the causes of the problems in the operation of the spiral plate heat exchanger, which is of great significance to the safe operation of the heat exchanger station and the work of energy saving and consumption reduction.
