Embodiment Construction
[0025] The present invention will be described below in conjunction with the accompanying drawings.
[0026] Such as figure 1 , figure 2 As shown, the thermal insulation device for the heat exchanger head of the present invention includes a profiled heat preservation cover arranged on the heat exchanger head. It is set according to the shape of the heat exchanger, so that the shape characteristics of the heat exchanger can be easily judged from the outside to facilitate maintenance. It can also make the profiling thermal insulation cover close to the heat exchanger, reduce the internal gap of the profiling thermal insulation cover, and improve the thermal insulation effect. The head 1 is installed on the head of the heat exchanger, and the flange 2 is installed on the flange of the heat exchanger. The shape of the head 1 is similar to a bowl, and the shape of the flange 2 is similar to a cylinder. The middle part of the flange part 2 protrudes outwards, and the protruding p...

The invention relates to a reusable attemperator for a heat exchanger shell cover. The attemperator comprises a profiling insulating sleeve arranged at the heat exchanger shell cover and is characterized in that the profiling insulating sleeve is of a layered structure which comprises an outer protective layer and an inner lining thermal-protective coating from outside to inside; and hung nails are distributed inside the outer protective layer, and the tail ends of the hung nails penetrate through the inner lining thermal-protective coating and are provided with locking plates. As the profiling insulating sleeve is of a layered structure and is fixed into a whole through the hung nails and the locking plates, not only can a good heat insulation effect be achieved, but also disassembly and overhaul is convenient, and the profiling insulating sleeve can be used repeatedly, i.e., the inner lining thermal-protective coating inside the outer protective layer can be replaced directly when the attemperator for the heat exchanger shell cover is disassembled. Compared with the bonding mode of fixing an insulating layer in the prior art, according to the invention, the inner lining thermal-protective coating can be stripped easily from the outer protective layer when the inner lining thermal-protective coating is replaced, and further a new inner lining thermal-protective coating can be installed so as to achieve a reusable goal.
Description
technical field [0001] The invention belongs to a heat preservation device for a heat exchanger, in particular to a reusable head heat preservation device for a heat exchanger. Background technique [0002] Heat exchangers are general-purpose equipment in chemical, petroleum and many other industrial sectors. They play an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers. very extensive. Due to the different production scales, properties of materials, and heat transfer requirements, there are various types of heat exchangers. According to the principle and method of heat exchange between cold and hot fluids, heat exchangers can basically be divided into three categories. : Mixed type, heat storage type, partition type. [0003] The head of the heat exchanger is connected to the heat exchanger body through the flange, and the heat exchanger body is kept insulated by wrapping the insul...
