Energy-saving freezing pipe for freezing underwater

Abstract

The invention discloses an energy-saving freezing pipe for freezing underwater, and belongs to the technical field of underwater vertical freezing equipment. The energy-saving freezing pipe for freezing underwater comprises a freezing pipe, a liquid feed pipe and a liquid return pipe, wherein the top of the freezing pipe is fixed with a sealed cover plate, the local freezing level part of the freezing pipe is provided with a partition plate, thermal insulation material is filled between the sealed cover plate and partition plate, the liquid feed pipe stretches to the bottom of the freezing pipe after passing though the sealed cover plate and partition plate, the liquid return pipe passes through the sealed cover plate and partition plate to form a pipe loop with the liquid feed pipe, an outer sleeve is arranged outside the freezing pipe, the upper end of the outer sleeve is high than the water level and the lower end is pressed into soil at the river bottom, and a heat preserving plate is arranged between the outer sleeve and freezing pipe. When the energy-saving freezing pipe for freezing underwater is in construction, the outer sleeve is firstly arranged in the river bottom about 1 meter, drilling construction is performed under the guiding of the outer sleeve, after the hole is drilled, the energy-saving freezing pipe which has been processed is put into the drill hole and then can be connected with a freezing system to start to freeze. The energy-saving freezing pipe for freezing underwater has the advantages of simplicity and convenience to process and manufacture, low cost, convenience to use, capability of preventing the cold loss of non-frozen areas.

Description

technical field [0001] The invention relates to an underwater vertical freezing device, in particular to an energy-saving freezing pipe for underwater freezing. Background technique [0002] During underwater freezing construction, since the unfrozen area is in the water, the turbulent flow of water caused by the cooling capacity and the flow of river and river water will take away a large amount of cooling capacity during freezing, resulting in a large loss of cooling capacity required for freezing, and the waste is obvious. At the same time, it interferes with the calculation of the cooling capacity required for freezing, causing a large deviation between the calculation and the actual situation. In severe cases, the uncertainty of the freezing design may cause the failure of the freezing reinforcement construction. Contents of the invention [0003] In order to solve the above problems, the present invention provides an energy-saving freezing tube for underwater freezin...
