With the improvement of living standards, people have higher and higher requirements for the environment. With people's understanding and attention to healthy life
As a kind of plate heat exchanger, plate condenser is specially designed for condensing condition. When the condensing capacity is small and the temperature is high,
working principle:
In industrial production, it is often necessary to evaporate a large amount of water, consume a large amount of energy, heat the water to produce steam, and then condense the steam to achieve the purpose of evaporating water. These vapors contain a lot of latent heat, so they should be recycled.
Maximum temperature:
NBR: 130 degrees
EPDM: 160 degrees
Service life:
About 1 year, in the absence of chemical corrosion.
General reference temperature:
10 degrees below maximum, about 2 years.
10 degrees above the maximum. B: About six months.
The advantages of plate heat exchanger are as follows:
1, safe and reliable use
Two sealing devices are designed between the plates,
2, the cooling water is small
Plate heat exchanger due to its geometric shape of the flow channel, and the two liquids are very high thermal efficiency, so the cooling water consumption can be greatly reduced. It also reduces installation costs of pipes, valves and pumps.
Analysis of common problems in the process of maintenance of plate heat exchanger, compared with ordinary plate heat exchanger, for the maintenance of brand plate heat exchanger or to pay attention to some problems, so as to avoid the failure of maintenance, affecting the normal use of heat exchanger. Maintenance personnel in the plate heat exchanger maintenance, do not ignore the following points of special attention.
1、 It is not suitable to use plate heat exchanger in the temperature range of 250 ℃. The design temperature of heat exchanger mainly depends on the temperature that its sealing gasket can bear. When using rubber elastic gasket, the maximum temperature is less than 180 ℃; If the gasket is made of compact asbestos, the maximum temperature can reach 250 ~ 260 ℃.
Plate heat exchanger is a kind of integrated heat transfer equipment, which is controlled by plate heat exchanger, circulating pump, make-up water pump, thermometer, pressure gauge, all kinds of sensing equipment, pipeline and valve, heat exchanger and central control, district heating (cooling) adjustment machine, and can also modularize and add make-up water system, constant pressure system, water treatment system, variable frequency medium control system Only auxiliary subsystems such as calorimeter and network communication control system can form a complete plate heat exchange unit.
