Multifunctional micro-channel condenser for multi-effect distilled water machine

Abstract

The invention relates to the technical field of medical pharmacy, in particular to a multifunctional micro-channel condenser for a multi-effect distilled water machine. The heat exchanger comprises a shell and a core body arranged in the shell, the core body comprises a plurality of core plates which are compounded together side by side, a plurality of transverse flow channels are arranged on the side walls of the front sides of the core plates in odd rows in parallel in the vertical direction of the core plates, and each transverse flow channel penetrates through the side walls of the left side and the right side of the corresponding core plate. A plurality of longitudinal flow channels are arranged on the front side walls of the even-numbered columns of core plates side by side in the horizontal direction, each longitudinal flow channel penetrates through the upper side walls and the lower side walls of the core plates, and the shell comprises sealing plates arranged on the front sides and the rear sides of the core plates in an abutting mode. The condenser is reasonable in structural design and integrates the functions of preheating, condensation and accurate temperature control, the condenser adopting the micro flow channel is high in heat exchange efficiency and smaller in size under the same heat exchange area, no dead angle exists in the micro flow channel, residual liquid cannot be generated, the risk of generating microorganisms is effectively reduced, and the problems existing in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of medical pharmacy, in particular to a multifunctional micro-channel condenser for a multi-effect distilled water machine. Background technique [0002] Water for injection is mainly purified water or water formed by condensation of ionized water after distillation, so it is also called double distilled water. At present, the preparation of water for injection mainly adopts the distillation method, and the distilled water machine is used for production. The commonly used ones include tower distilled water machine, multi-effect distilled water machine and pneumatic distilled water machine. In the medical and pharmaceutical industry, the multi-effect distilled water machine is more used to prepare water for injection, mainly because it has the characteristics of low energy consumption, high output, excellent water quality and high degree of automation, so it is widely used. [0003] At present, the multi-eff...

AI Technical Summary

Problems solved by technology

Therefore, increasing the length of the tubes or the diameter of the shell is an effective way to improve the heat exchange efficiency, but this undoubtedly increases the volume and weight of the multi-effect distilled water machine

[0004] In the limited space of the pharmaceutical factory, there are requirements for the overall weight and installation height of the multi-effect distilled water machine.

When the shell-and-tube heat exchanger is increased to a certain length, it cannot meet the on-site assembly requirements and increases the difficulty of transportation

Therefore, overlapping placement is adopted, but the overlapping placement of the tube-and-tube heat exchanger greatly increases the curb weight, and the strength of the skid-mounted support of the multi-effect distilled water machine increases at the same time, resulting in an increase in production costs

Moreover, in the installation requirements of the overlapping double-tubesheet heat exchanger, the heat exchanger needs to have a certain inclination angle to ensure that there is no liquid residue in the tube shell. When the diameter and length of the double-tubesheet heat exchanger increase, the residual liquid The risk will also increase accordingly

Double-tube-sheet heat exchangers are a common practice in the application of multi-effect distilled water machines. Unreasonable design and installation will seriously affect the efficiency and production costs of multi-effect distilled water machines.
