The spiral plate heat exchanger is a gas pressurizing component of the oxidizer tank in the whole engine system, which is used to provide the propellant supply pressure required for the normal operation of the engine. In the development process, the design requires that the inner and outer brazed and non brazed surfaces of the spiral plate heat exchanger be electroplated with Ni10~15 μ M, in which the coating on the brazing surface is required for subsequent welding with other components, and the coating on the non brazing surface is used as the high-temperature oxidation resistance protective coating during operation.

Small cylinders or rectangles can be welded to the spiral plate heat exchanger. Its function is to maintain the distance between spiral plates and keep the distance between them consistent. It can greatly improve the rigidity, stability and strength of the spiral plate, and can also promote the flow of fluid and enhance its heat transfer effect. When most manufacturers use a fixed distance, it is caused by the concentricity of automobile manufacturing. Its center part will leave a residual bulge. In the volume of the spiral plate, the damage of the plate surface to the plate is very large, and the bearing capacity can be reduced. Semicircular simplified body. The blanking and shaping industry can effectively solve this problem.

Why to Use Plate Heat Exchanger in Soft Water Cooling of Blast Furnace Body

Why to Use Plate Heat Exchanger in Soft Water Cooling of Blast Furnace Body

2018-10-22

Air cooler is mostly used for soft water cooling of blast furnace body. As the air cooler takes air as the medium and is greatly affected by seasons, the temperature of soft water entering the blast furnace will also change with seasons. The air cooler tube bundle is prone to corrosion and water leakage. When the heat exchange area of the air cooler is reduced, it is easy to increase the temperature of soft water in the blast furnace. With the improvement of ironmaking process and the increase of blast furnace utilization factor, the safe production and service life of blast furnace have been seriously affected.

The mechanical expansion of spiral plate heat exchanger is to use the pressure of the ball of the tube expander to make the metal wall at the end of the tube subject to internal extrusion and expansion. When the metal of the outer wall of the tube and the hole wall of the tube plate deforms, the deformation of the tube is far greater than the deformation of the hole wall, so that the tube will have flow plastic deformation. When the tube expander is removed, the hole wall shrinks elastically. Hold the expanded part of the tube tightly, so that the tube is closely connected with the tubesheet. In order to make the pipe resistant to certain pulling stress, the extended part of the pipe can also be turned out of the bell mouth shape with the help of the flanging expander to prevent the pipe from being pulled out of the pipe hole during operation.
