Tangential cylindrical graphite heat exchange block

Technical Field

The utility model relates to the technical field of chemical instruments, in particular to a tangential cylindrical graphite heat exchange block.

Background

The graphite heat exchanger can be divided into three types of block hole type, shell-and-tube type and plate type according to the structure, the block hole type is formed by assembling a plurality of block graphite components with holes, the shell-and-tube type heat exchanger occupies important positions in the graphite heat exchanger, and is divided into two types of fixed type and floating head type according to the structure, and the plate type heat exchanger is manufactured by bonding graphite plates. The heat conductivity coefficient is higher than that of a plurality of metals, is only inferior to copper and aluminum, is 2 times larger than carbon steel, is 5 times larger than stainless steel, is the first of nonmetallic materials, and is suitable for manufacturing various heat exchange devices. Low linear expansion coefficient, high temperature resistance and thermal shock resistance. The surface is not easy to scale and has no pollution. The machining performance is good. The density is small and the weight is light.

The defects of the conventional tangential cylindrical graphite heat exchange block are as follows: the graphite heat exchange block has the main defects that once leakage is difficult to find out and difficult to repair, the shell-and-tube type graphite heat exchanger has the defects that the strength of a graphite tube is relatively low, the pressure of steam used cannot exceed 0.15MPa, the flow rate of a heated medium is low and can only be controlled to be 2-3 m/s, the temperature difference between an inlet and an outlet can only be controlled to be 2-4 ℃, the volume of the heat exchanger is large, meanwhile, the heat transfer efficiency is low, the condition of uneven stress occurs, the viscosity of the medium is high, and the conventional structure is easy to block, so that the use effect and the efficiency of the graphite heat exchange block are reduced.

It is therefore necessary to develop a tangential cylindrical graphite heat exchanger block.

Disclosure of Invention

The utility model aims to provide a tangential cylindrical graphite heat exchange block, which is characterized in that a longitudinal pipe and a transverse pipe are arranged, the longitudinal pipe is arranged on the outer wall of a central pipe on the inside of a heat exchange block shell in an inclined manner, and the radial directions of the transverse pipe and the central pipe deviate by an angle, so that fluid can enter and exit a transverse pipe duct in a rotating manner along the same direction, the occurrence of resistance of the fluid can be effectively reduced, the turbulent flow effect is also facilitated, the heat transfer efficiency is further improved, meanwhile, the integral stress condition of the graphite heat exchange block is good, the occurrence of uneven stress is avoided as much as possible, the use effect and the efficiency of the cylindrical graphite heat exchange block are effectively realized, and the problem that the effect of the graphite heat exchange block is poor and the efficiency is influenced in the background technology is solved.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the tangential cylindrical graphite heat exchange block comprises a heat exchange block shell, wherein a central tube is arranged in the inner center of the heat exchange block shell;

the outer wall of the central tube is uniformly provided with longitudinal tubes, and transverse tubes are uniformly arranged among the longitudinal tubes.

Preferably, the longitudinal pipes are in an array square matrix and distributed on the annular surface of the central pipe along the pore canal along the axial direction.

Preferably, one end of the longitudinal pipe is fixedly connected with the inner wall of the heat exchange block shell, and one end of the longitudinal pipe is communicated with the heat exchange block shell.

Preferably, the transverse tubes are arranged in four groups, and the four groups of transverse tubes are distributed between two groups of longitudinal tubes.

Compared with the prior art, the utility model has the beneficial effects that:

through being equipped with vertical pipe and horizontal pipe, install the vertical pipe with the central tube outer wall on the heat transfer piece shell is inside to with horizontal pipe and the skew angle of central tube radial direction, when can making fluid business turn over horizontal intraductal pore, all follow same direction rotation entering, the condition that can effectually reduce fluidic resistance takes place like this, also be favorable to producing turbulent effect, and then improve heat transfer efficiency, the holistic atress situation of graphite heat transfer piece is good simultaneously, the condition of avoiding the atress inhomogeneous takes place as far as possible, the effectual cylinder type graphite heat transfer piece that has realized has tangential effect, cylinder type graphite heat transfer piece result of use and efficiency have also been improved.
