Abstract
The invention discloses a reverse-rotation heat exchanger. The reverse-rotation heat exchanger is characterized in that: a high-temperature reaction medium and a low-temperature reaction medium in a chemical reaction move forwards in respective concentric pipelines in opposite rotation directions, at the same time, the temperature of the low-temperature medium which requires temperature raising is raised and the temperature of the high-temperature medium which requires temperature reducing is reduced, and the media play a role in stirring so as to improve the collision probability of the reaction and improve reaction efficiency. The heat exchanging efficiency is 2.5 times that of a straight-pipe heat exchanger with the same pipe diameter, and 1.6 times that of a half-pipe heat exchanger with the same pipe diameter. Aiming to meet the requirements of various processes and heat exchanging areas, a special unit of the combined reverse-rotation heat exchanger can be combined randomly. The combined reverse-rotation heat exchanger has the advantages of saving energy, cooling water, operating cost and equipment investment greatly, improving the yield of chemical products, along with simple and convenient operation, simple and flexible combined arrangement and good utilization prospect.
Description
Technical field
The present invention relates to the chemical industry heat transmission equipment, belong to chemical technology field.
Background technology
In the prior art, heat transmission equipment divides heater, condenser two big classes.As heat certain medium, and must or burn the High Temperature Gas of burning and generating and heat this medium with the high temperature and high pressure steam that is higher than this medium, this will consume a large amount of energy and operating cost; As certain medium of condensation, palpus cool off this kind medium with the evaporation of refrigerant liquid (as water), and the refrigerating fluid of use reclaims (as making steam form water) as palpus, the corresponding reclaiming clean of palpus manufacturing system, and the increase investment if do not reclaim, will cause waste.
In chemical-process, the ubiquity pyroreaction, low temperature is collected the phenomenon of product, in order to improve product yield, what have uses second order reaction, and what have uses third-order reaction, and each order reaction all is once to heat up and the process (as Claus method Recovered sulphur technology) of lowering the temperature, its energy consumption, operating cost is bigger with investment.
As with the high-temperature medium of the first order, the high temperature section of second, third order reaction that goes to heat, that third-order reaction, just as the first order reaction of dilatation, this will reduce the efficient of chemical reaction in theory.
Summary of the invention
For the customer service the deficiencies in the prior art, the invention provides a kind of combined reverse-rotation heat exchanger, with the high-temperature medium of lowering the temperature in the chemical reaction and the cryogenic media that needs to heat up in the pipeline separately of concentric, advance to opposite direction of rotation operation, significantly improve heat transfer rate, make high-temperature medium reach the purpose of cooling simultaneously, cryogenic media reaches the purpose of intensification, with heater and condenser, it is one that agitator closes three, greatly reduced energy resource consumption, water power consumes, operating cost, equipment investment, combined reverse-rotation heat exchanger can be combined into all size requirement easily, the heat transmission equipment of various various heat exchange areas is to be used in various technological requirements.
The present invention is achieved through the following technical solutions: a kind of combined reverse-rotation heat exchanger is characterized in that high-temperature medium enters interior pipe, and the water conservancy diversion blade of certain angle and certain altitude is arranged in the interior pipe.High-temperature medium advances in interior pipe rotation; Simultaneously cryogenic media enters from outer tube, certain angle is arranged in the water conservancy diversion blade of certain altitude and opposite in the water conservancy diversion direction of interior pipe in the outer tube, and cryogenic media advances in the outer tube rotation, and is opposite in the direction of interior pipe high-temperature medium rotation.Increased substantially heat exchange efficiency, increased the collision probability (stirring action) between compound molecule, increased the synthetic ratio of compound, and will heat, condensation, stirring three process finish in an equipment.
Aforementioned a kind of combined reverse-rotation heat exchanger is characterized in that described equipment is to combine with discrete cell, can be combined into needed heat exchange area equipment easily according to various requirement.
The invention has the beneficial effects as follows:
1. heater, condenser, agitator being closed three is one, can save a large amount of energy, water source, operating cost and equipment investment, can improve product yield.
2. heat exchange efficiency height is 2.5 times with the caliber straight pipe heat exchanger, is 1.6 times with caliber semicanal heat exchanger.
3. combination is flexible, wide adaptability.

The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of combined reverse-rotation heat exchanger, and Fig. 2 is the cutaway view of Fig. 1 along the A-A line, and Fig. 3 is the enlarged drawing at Fig. 1,2,18 places.
With reference to Fig. 1, Fig. 2, Fig. 3, the interior pipe 4 of combined reverse-rotation heat exchanger is the high-temperature medium passage, and high-temperature medium can be a gas phase, also can be liquid phase; Interior blade 7 rotates high-temperature medium in a certain direction and advances.Outer tube 3 is passages of cryogenic media, and cryogenic media can be a gas phase, also can be liquid phase; Outer blade 8 rotates cryogenic media in a certain direction and advances, and its direction of rotation is opposite with the high-temperature medium direction of rotation.Flange 1 be used between the unit or with miscellaneous equipment between be connected, take over 5 with flange 6 are imports of cryogenic media, take over 15 with flange 16 are cryogenic media outlets after heating.Expansion joint 12 is adjusting devices that the inner and outer pipes temperature differs, expands and differ.Supporting 17 is positioners of inner and outer pipes, and the parts of filler were loaded in the inner and outer pipes sealing when seal groove 18 was unit combination.Low temperature road cover plate 2 can prevent that cryogenic media from leaking when being connected with miscellaneous equipment or using separately, must not install when unit combination.
The present embodiment difference from Example 1 is that according to the requirement of different process, high-temperature medium moves at outer tube, and cryogenic media moves at interior pipe, can reach identical purpose.
The present embodiment difference from Example 1 is that high-temperature medium can enter from opposite direction with cryogenic media.
Below preferred embodiment discloses the present invention, and so it is not in order to restriction the present invention, and the technical scheme that equal replacement of all employings or equivalent transformation mode are obtained all drops in protection scope of the present invention.
