Embodiment Construction

[0012] The specific implementation of the present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 , figure 2 As shown, the present invention mainly includes a header compression cover 1, a compression ring 2, a header positioning seat 3, a header 4, a spiral tube 5, a casing 6, a liquid discharge valve 7, a support 8, and a steam inlet pipe seat 9. Outlet pipe seat 10.

[0014] The casing 6 is a closed hollow cylinder with spherical surfaces at both ends. A header 4 is installed at both ends of the casing 6, and the header 4 is made of a titanium alloy tube. Smooth titanium alloy tubes are rolled into spiral tubes 5 of two diameters in parallel without gaps, coaxially stacked on each other, and the radial distance is consistent. The two ends of the two spiral tubes 5 are welded into one body with the two headers 4. fixed in the housing 6. Two manifold 4 ports are welded with manifold positioning seat 3, and ma...

Abstract

The present invention relates to a sea-water and fresh-water dual-purpose spiral tube condenser equipment. It mainly comprises header clamping cap, clamping ring, header positioning seat, header, spiral tube, shell body, liquor-discharging valve, supporting seat, steam inlet pipe seat and liquor outlet pipe seat. Said invented shell body is a hollow closed cylinder body whose two ends are made into the form of sphere, and said two ends are respectively equipped with one header. The spiral tubes with two different diameters are made by gapless parallelly-coiling smooth titanium alloy tubes and mutually cover-superposed coaxially, two ends of the spiral tube are welded together with headers, and fixed in the shell body. The refrigerant is sea-water or fresh-water. Said invention is compact in its structure and is convenient in installation.

Description

technical field [0001] The invention relates to a condenser, in particular to a seawater and freshwater dual-purpose spiral tube condenser which can use highly corrosive seawater as a refrigerant, and belongs to the technical field of refrigeration equipment in refrigeration engineering. Background technique [0002] The performance characteristics of various existing condensers have their own advantages and disadvantages, but for refrigeration devices operating in the ocean, on the coast, or for sea-going ships, using seawater or seawater and freshwater alternately as refrigerants, the above-mentioned condensers all reflect existing defects. Seawater has a corrosive effect, and the condensers in the above applications can only be made of seawater corrosion-resistant materials, otherwise, the existing various condensers will corrode and rust in a short period of time. Seawater corrosion-resistant materials such as titanium alloy pipes have special welding technology requirem...
