Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can practice the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
Example 1
In the embodiment, the YKC type round block graphite heat exchanger which is applied more in the industry is improved, and as frequent pressure changes need to be borne on a heat exchange interface of a vertical hole in the operation process of the invention, the corrosion-resistant wheel in the scheme of the invention is not suggested to be used on a tubular graphite heat exchanger before a graphite tube with higher pressure resistance appears.
As shown in fig. 1-2, a high-efficiency block-and-hole graphite heat exchanger comprises an upper cover body 1, a heat exchange part 2 and a lower cover body 3 which are arranged from top to bottom in sequence; the upper cover body is provided with a material inlet 4, the lower cover body is provided with a material outlet 5, the heat exchange part comprises a shell and a graphite inner container arranged in the shell, and a gap is formed between the shell and the graphite inner container to form a heat exchange flow channel 6; the graphite liner is formed by splicing a plurality of block-hole graphite heat exchange pieces 7 and a medium sheet 8 (made of polytetrafluoroethylene material) up and down; the upper part of the shell is provided with a water or gas circulating medium outlet 9, and the lower part of the shell is provided with a water or gas circulating medium inlet 10; a plurality of rows of cross holes 11 and vertical holes 12 which are arranged in a staggered mode are processed on the block-hole type graphite heat exchange piece, a straight channel formed by the vertical holes is communicated with the material inlet and the material outlet, and a bent channel formed by the cross holes of the plurality of block-hole type graphite heat exchange pieces is communicated with the circulating medium inlet and the circulating medium outlet; because the effective length of the bent channel formed by the transverse hole is far greater than the straight channel formed by the vertical hole, the heat exchange efficiency of the transverse hole is higher than that of the vertical hole, the setting density of the vertical hole has to be increased in order to improve the heat exchange efficiency of the vertical hole, the pressure-bearing strength of the block hole type graphite heat exchange piece is reduced to a certain extent, if the heat exchange efficiency of the vertical hole can be improved, the necessary setting density of the vertical hole can be reduced, meanwhile, the block hole type graphite heat exchange piece can be designed to be flatter, and the whole volume of the block hole type graphite heat exchanger is favorably reduced.
A rotatable corrosion-resistant wheel 13 is arranged in the middle of the inner side of the upper cover body or the lower cover body (at the moment, a material inlet can only be eccentrically arranged), the corrosion-resistant wheel is an impeller, the impeller at least comprises one blade 14, the blade is close to one side of the graphite liner, namely the bottom surface 15 of the blade is a plane, the bottom surface of the blade is arranged in parallel to the surface of the adjacent graphite liner, and a gap a exists between the bottom surface of the blade and the surface of the adjacent graphite liner; the material of the corrosion-resistant wheel can be selected from graphite, glass, ceramic and the like. If the material inlet is arranged at the center of the upper cover body, the material inlet can be realized by arranging the rotating shaft and the corrosion-resistant wheel in an inclined manner, wherein the rotating shaft is eccentrically arranged on the upper cover body (the connecting position of the rotating shaft and the upper cover body is not arranged at the center of the upper cover body), the surface of the adjacent graphite inner container is also a corresponding inclined surface, and the corrosion-resistant wheel rotates along with the inclined surface; thus, the direction of movement (or plane of movement) of the bottom surface of the erosion wheel or blade need not be perpendicular to the axis of the vertical bore.
The corrosion-resistant wheel can at least simultaneously cover a row of vertical holes in the radial direction of the block-hole type graphite heat exchange piece or a curved vertical hole. When the corrosion-resistant wheel rotates, the flow velocity of fluid in the vertical hole temporarily covered by the corrosion-resistant wheel is reduced or stagnated, so that the pressure in the covered vertical hole is increased, the corrosion-resistant wheel continues to rotate, the originally covered vertical hole can be restored to a passage, the fluid can be restored to normal flow, the pressure in the vertical hole is restored to normal, in the period, the pressure change in the vertical hole enables a large amount of vortex to be generated in the vertical hole, the vortex can greatly increase the scouring effect of the fluid on the inner wall of the vertical hole, and further the heat exchange efficiency in the vertical hole is improved;
the radius of the corrosion-resistant wheel is matched with that of the graphite inner container.
The corrosion-resistant wheel is rotatably connected with the upper cover body or the lower cover body through a rotating shaft 16. According to different states of materials, the corrosion-resistant wheel can be preferentially arranged at one gaseous end of the materials, and of course, the corrosion-resistant wheel can also be arranged on the upper cover body or the lower cover body; in this embodiment, the rotating shaft is disposed at the center of the upper cover body, the material inlet is eccentrically disposed, and two material inlets are disposed.
The corrosion-resistant wheel is driven by a motor, and the motor is arranged on the outer side of the block-hole type graphite heat exchanger and drives the corrosion-resistant wheel through a rotating shaft.
When the rotating speed of the corrosion-resistant wheel is constant, the size of a is positively correlated with the number b of rows which can be plugged by the corrosion-resistant wheel at the same time. The smaller a is, the better the plugging effect on the vertical hole is, the more obvious the pressure change in the vertical hole is, and the pressure change cannot be too violent in consideration of the brittleness of graphite and is controlled within a proper range; and when the rotating speed r is larger, the single plugging time of the corrosion-resistant wheel to the vertical hole is shorter; therefore, the change of the pressure in the vertical hole can be kept within the pressure variation range which can be borne by the block-hole graphite heat exchange piece by means of changing the rotating speed of the motor, adjusting the height position of the corrosion-resistant wheel, changing the size of a, increasing or decreasing the number of impellers and the like. In practical application, within the range of nominal pressure of the equipment, can be approximately equal to kb/n (p) according to a1-p2) The reference is made to adjust the size of a, wherein a is the gap between the bottom surface of each blade and the surface of the adjacent graphite liner, b is the number of rows which can be simultaneously blocked by the corrosion-resistant wheel, and k is a constant according to the actual conditionA compensation coefficient determined by using conditions, n is the rotating speed of the corrosion-resistant wheel, p1Is the maximum pressure value in a fluctuation period in the vertical hole or the maximum pressure value which can be born in the vertical hole, p2The minimum pressure value in a fluctuation period in the vertical hole is 0; in actual use, other influencing factors may exist, and the debugging still needs to be optimized. Once a is determined, in order to ensure the safety of the block-hole type graphite heat exchange piece, the adjustment is not suitable, and n and the like are adjusted when needed, so that the height of the corrosion-resistant wheel is not needed to be set to be adjustable, and if a is actually needed to be adjusted, the adjustment can be realized by adopting methods of adjusting the thickness of a medium sheet, selecting a sleeve type adjustable rotating shaft and the like.
And a lining pipe 17 which is matched with the inner diameter of the vertical hole is arranged in the vertical hole. The material in the vertical hole forms the scouring effect of vortex and the loss of the inner wall of the vertical hole is aggravated by pressure change, so that a replaceable lining pipe is necessary to be additionally arranged, the lining pipe is convenient to overhaul and replace regularly, and the service life of the block hole type graphite heat exchange piece is prolonged. The lining pipe can select a setting mode that the lining pipe penetrates through all the block hole type graphite heat exchange pieces up and down, and can also select a setting mode that the lining pipe is respectively arranged in the vertical hole of each block hole type graphite heat exchange piece, and the later mode is lower in cost when the lining pipe is overhauled and replaced.
The inner diameter of the lining pipe is unchanged.
The lining pipe is formed by splicing a plurality of arc-shaped graphite sheets 18 around the axis of the lining pipe, and the arc-shaped graphite sheets are bonded and fixed. The processing degree of difficulty of column graphite pipe is great relatively, consequently, adopts a plurality of arc graphite flakes to encircle the interior bushing pipe that the concatenation formed lower in manufacturing cost, because on the downthehole pressure to interior bushing pipe can transmit the dispersion to erecting downthehole wall in the vertical, can suitably reduce to the intensity requirement of interior bushing pipe, consequently can adopt special glue to bond fixed arc graphite flake, of course, also can adopt the mode of a plurality of graphite nozzle stub upper and lower concatenations to form interior bushing pipe.
The outer edge of the upper end of the lining pipe is fixed with a limiting ring 19, and the upper end of the vertical hole is a counter bore matched with the limiting ring. So as to facilitate the installation and replacement of the lining pipe.
In addition, if necessary, a plurality of annular grooves can be processed on the outer side of the lining tube, and fixing rings are arranged in the annular grooves to restrain arc-shaped graphite sheets (auxiliary fixing).
In tests, the heat exchange efficiency of the block-hole graphite heat exchanger is found to be at least 2% higher than that of a heat exchanger without the corrosion-resistant wheel in the same type if a and n are properly adjusted. The invention can be used as a heater, a cooler and a condenser, and can be added with a gas-liquid separator, an elastic automatic compensating device for expansion with heat and contraction with cold of a graphite heat exchanger and the like according to requirements when used for different purposes.
Example 2
As shown in fig. 3, similarly to example 1, there is a difference in that the inner diameter of the inner liner tube is regularly changed. In the embodiment, the inner diameter of the main body of the lining pipe is unchanged, but at intervals, the lining pipe is provided with narrow parts 20, the inner diameter of each narrow part is reduced by 5% -20% compared with the inner diameter of the corresponding main body, the inner diameter of the lining pipe is regularly changed, more turbulence is generated locally in the lining pipe, and the heat exchange efficiency of the block-hole graphite heat exchanger can be improved to a certain extent. The arrangement mode that the lining pipes are formed by annularly splicing the arc-shaped graphite sheets also enables the cost for processing the graphite lining pipes with the regularly changed inner diameters to be lower (because the graphite is brittle, the difficulty of processing the lining pipes with the regularly changed inner diameters by one-step molding is higher, the yield is low, and the cost is high).
Example 3
Similar to the embodiment 1, the corrosion-resistant wheel is characterized in that the corrosion-resistant wheel adopts an impeller, the upper surface of blades of the impeller is an inclined surface or a curved surface, and the impeller can be driven to rotate only by the flow of materials without external drive. Although this saves external drive, the speed of rotation of the impeller is not controllable, and this method is not the preferred drive for the erosion resistant wheel.
Example 4
As shown in fig. 4, similar to example 1, the corrosion-resistant wheel is different in that the corrosion-resistant wheel is a disc-type porous wheel 21 with a plane bottom, the number of holes on the disc-type porous wheel is 2 times of that of the vertical holes, and each hole can be aligned with one vertical hole during the rotation of the corrosion-resistant wheel. The perforated disc acts like an impeller to temporarily cover the vertical holes during rotation.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable to various fields of endeavor for which the invention may be embodied with additional modifications as would be readily apparent to those skilled in the art, and the invention is therefore not limited to the details given herein and to the embodiments shown and described without departing from the generic concept as defined by the claims and their equivalents.
