Abstract
The utility model discloses an electrical heating cast aluminum vaporization heat exchanger. The electrical heating cast aluminum vaporization heat exchanger comprises a shell (1). A pipe coil (2) and a plurality of heating rods (3) are arranged in the shell (1), and all the heating rods (3) are controlled through a control circuit in an electric control cabinet (4) located above the shell (1). The electrical heating cast aluminum vaporization heat exchanger is characterized in that cast aluminum or cast aluminum alloy is filled into the space, except space occupied by the pipe coil (2) and the heating rods (3), of a cavity in the shell (1). The electrical heating cast aluminum vaporization heat exchanger is simple in structure, ingenious in design, reasonable in layout, high in heat exchange efficiency and capable of achieving high-temperature heating.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of electrical heating cast aluminium vaporization heat exchanger.
Background technology
Cryogen (liquid oxygen, liquid nitrogen, liquid hydrogen, liquid argon, LNG, LPG, ethene etc.) and corrosive fluid (HCL, H2SO4, SiH4 etc.) are inflammable, explosive, even there is contaminative, in chemical reaction or production process, need specific temperature conditions, use vaporization heat exchanger to vaporize by it.Traditional vaporization heat exchanger is water-bath type vaporization heat exchanger, utilizes water or ethylene glycol as heat transfer medium, the fluid in indirect heat exchanger tube, and the mode of the non-direct contact of this employing can guarantee constant temperature, can avoid overheated simultaneously.But the defect of this heat exchanger is: before carrying out the vaporization of cryogen, first heat needs the temperature increase of water (or diethanol), therefore can affect vaporization rate, and because the boiling point of heat transfer medium itself is lower, has also limited the temperature of vaporization.In sum, need now a kind of novel vaporization heat exchanger that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, and heat exchange efficiency is high, and can realize the electrical heating cast aluminium vaporization heat exchanger of high-temperature heating.
Technical solution of the present utility model is: a kind of electrical heating cast aluminium vaporization heat exchanger, comprise housing 1, in housing 1, be provided with coil pipe 2 and a plurality of heating rod 3, all heating rods 3 are all controlled by being positioned at the control circuit of the electrical control cubicles 4 on housing 1 top, it is characterized in that: in the cavity in described housing 1 except coil pipe 2 and heating rod 3, be all filled with cast aluminium or cast aluminium alloy.
Compared with the existing technology, tool has the following advantages the utility model:
The electrical heating cast aluminium vaporization heat exchanger of this kind of version, it is simple in structure, designs ingenious, rationally distributed.It is slow for the existing firing rate of traditional water-bath type vaporization heat exchanger, heat conversion is low, cannot realize the defect of high-temperature heating, design a kind of special construction, in this kind of structure, utilize cast aluminium or cast aluminium alloy to substitute traditional liquid heat transferring medium, because cast aluminium (or cast aluminium alloy) is than water, its thermal conductivity factor increases (be water more than 300 times) greatly, therefore can significantly improve heat exchange efficiency; The fusing point of cast aluminium, also far above the boiling point of water, therefore can be realized high-temperature heating (reaching as high as 300 ℃) simultaneously.This equipment, except having possessed the advantage of traditional water-bath type vaporization heat exchanger, also has the advantages such as volume is little, lightweight, the life-span is long, with low cost, and toggle speed is fast, and operation maintenance is convenient.Therefore market prospects widely that this vaporization heat transfer equipment is standby, are extremely conducive to apply in the art.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.As shown in Figure 1: a kind of electrical heating cast aluminium vaporization heat exchanger, comprise housing 1, in housing 1, be provided with coil pipe 2 and a plurality of heating rod 3, and all heating rods 3 are all connected with control circuit and unify control, control circuit is positioned at electrical control cubicles 4 inside that are arranged on housing 1 top, in housing 1 inside, the cavity part except coil pipe 2 and heating rod 3 is all filled with cast aluminium or cast aluminium alloy.
The course of work of the electrical heating cast aluminium gasification heat exchanger of the utility model embodiment is as follows: first by the fluid liquid that needs vaporization process, the entrance by coil pipe 2 delivers into coil pipe 2, then by control circuit, control heating rod 3 work, the cast aluminium contacting with heating rod 3 or cast aluminium alloy can conduct heat to coil pipe 2 rapidly, coil pipe 2 reaches after uniform temperature, by fluid liquid vaporization mobile in it, the gaseous fluid after vaporization is discharged by the outlet of coil pipe 2.
