In industrial production and community heating systems, heat exchange equipment is often used. There are various types of heat exchange equipment, and one of the most common types is the volumetric heat exchanger. It has advantages such as a high heat transfer coefficient and small floor space, as well as characteristics including high volume utilization rate and quick startup. This article will briefly introduce the advantages and characteristics of volumetric heat exchangers.
I. Advantages of Volumetric Heat Exchangers
High heat transfer coefficient: For water-water heat exchange, the heat transfer coefficient (K value) is increased by 80%, and the temperature drop value of the heat medium is increased by 35%. For steam-water heat exchange, the K value is increased by 35%, and the temperature drop value of the heat medium is increased by 25%.
More sufficient heat exchange: Due to the adoption of a special flow guiding device, the stagnant water area and cold water area in the tank are small, and the volume utilization rate reaches 95%.
Negligible shell-side head loss: This maintains the advantages of stable water supply, comfortable water use, energy conservation, and water conservation.
Small floor space requirement: The space required for extracting the tube bundle is small, and the tubes only need to be extracted in a single direction. This saves floor space and facilitates design, use, and maintenance.
Complete specifications, flexible and economical selection: It provides a greater range of options, especially for places where equipment height is restricted.
No trap required on the condensate pipe for steam-water heat exchange: When steam-water heat exchange is performed, the temperature of the condensate is low, so no trap is needed on the condensate pipe.
II. Characteristics of Volumetric Heat Exchangers
Large temperature drop of the heat medium: For steam-water heat exchange, the outlet temperature of the condensate is approximately 50°C, and traps need to be installed above and below the return pipe, which facilitates use and maintenance. For water-water heat exchange, the heat temperature drop is 2-2.5 times that of the same type of heat exchanger; high-temperature hot water at 120-150°C can be cooled to 70-75°C after heat exchange.
Good heat exchange and heat dissipation effects: It has good heat exchange effect, good heat dissipation effect, small heat dissipation loss, and realizes energy conservation. At the same time, when steam is used as the heat medium, it can recover approximately 15% of the condensate heat, which accounts for the total heat exchange capacity.
Small cold water area and high volume utilization rate: The cold water area in the exchanger is small, ensuring a high volume utilization rate.
Retains advantages of traditional volumetric heat exchangers: It maintains the advantages of large water storage capacity, low head loss, stable water supply, and easy scale removal.
Quick startup: Due to the special structure of this product, the generated hot water quickly reaches the hot water outlet at the top of the tank, and hot water can be supplied externally without heating most of the cold water.
High heat transfer coefficient: The elastic tube bundle uses heat transfer elements with high thermal conductivity. Combined with the reasonable internal structure of the heat exchanger, the performance of the heat exchanger is greatly improved.
Low scaling tendency: The heat exchange tubes are corrugated tubes, and the fluid that easily forms turbulence has a strong scouring effect on the wall of the heat exchange tubes. In addition, the elastic tube bundle itself has thermal compensation capacity and achieves a self-cleaning effect through thermal expansion and contraction, so scaling is less likely to occur.
Energy conservation: When steam is used as the heat medium, the temperature of the condensate of this product is lower than 30°C.
