Efficient reboiler

Abstract

The invention discloses an efficient reboiler which comprises a barrel, a lower seal head and an upper seal head are respectively mounted at two ends of the barrel through a lower shell ring and an upper shell ring, the lower shell ring and the upper shell ring are hermetically connected with two ends of the barrel through a lower pipe plate and an upper pipe plate, a heat exchange pipe is vertically mounted in the barrel between the lower pipe plate and the upper pipe plate, a plurality of baffle plates are further arranged in the barrel, the baffle plates are installed below the upper pipe plate through pipe spacers, the heat exchange pipe penetrates through the overlapped parts of the baffle plates, an air outlet is formed in the upper shell ring, a feeding port is formed in the lower shell ring, a liquid outlet is formed in the end, located at the feeding port, of the side wall of the barrel, an air inlet is formed in the end, located at the air outlet, of the barrel, a drain outlet is further formed in the lower part of the lower shell ring, and an impingement plate is arranged at the position, located at the air inlet, of the inner wall of the barrel. Impact on the baffle plates caused by introduced heating media is effectively avoided, meanwhile, the overall stability of the baffling channel is guaranteed, baffling channel deformation caused by baffle plate deformation is avoided, the service life is prolonged, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a high-efficiency reboiler. Background technique [0002] Reboilers are widely used in chemical plants. As the name suggests, reboilers (also known as reboilers) vaporize liquids again. Its structure is similar to that of a condenser, but one is used to cool down, while the reboiler is used to heat up and vaporize. [0003] The reboiler is often used in conjunction with the fractionation tower: the reboiler is a special heat exchanger capable of exchanging heat and having a vaporization space. The material level in the reboiler is at the same level as the fractionation column level. The liquid phase is supplied from the bottom line into the reboiler. Typically -% of the liquid phase is vaporized in the reboiler. The vaporized two-phase stream is sent back to the fractionation column, where the vapor phase components return to the column and pass upward through the ...

Problems solved by technology

[0004] In the prior art, baffles are installed in the cylinder in order to make the incoming borehole stay in the cylinder for a relatively long time. However, due to the unreasonable design and structure of the traditional baffles, the stability is poor, and it is easy to The heating medium that is fed in will impact it, especially at the entrance of the heating medium, which will cause the baffle to deform and affect the use
