Problems solved by technology
[0005] Therefore, the technical problem to be solved by the present invention is that during the operation of the MVR equipment, the corrosive gas in the secondary steam is likely to cause corrosion to the equipment, especially the compressor impeller, which makes the equipment easy to damage and has a short service life. The secondary steam scrubber for MVR system is used to remove corrosive gas in secondary steam, prevent corrosive gas from damaging compression equipment, and prolong the service life of equipment.

The invention discloses a secondary vapor scrubbing tower for an MVR (mechanical vapor recompression) system. The secondary vapor scrubbing tower for the MVR system comprises a vapor scrubbing tower body, and further comprises a liquid spraying pipe communicated with the inner part of the vapor scrubbing tower body and used for spraying scrubbing liquid into the vapor scrubbing tower body and a vapor outlet for discharging secondary vapor, wherein a secondary vapor inlet is formed in the top of the vapor scrubbing tower body, and a liquid discharging opening is formed in the bottom of the vapor scrubbing tower body. The scrubbing liquid is sprayed out from the liquid spraying pipe for scrubbing the secondary vapor entering from the secondary vapor inlet, ammonia, hydrogen chloride and other corrosive or odorous gases in the secondary vapor are absorbed and taken away by the scrubbing liquid, then the scrubbing liquid is discharged from the liquid discharging opening, and the clean secondary vapor is discharged from the vapor outlet. Before entering a compressor of an MVR evaporation system, the secondary vapor scrubbing tower is used for scrubbing the secondary vapor, so that damage of the corrosive gases in the secondary vapor to a compressor impeller can be prevented, and thus a good using working condition of the compressor is ensured, the service life of the compressor is prolonged, and the operation stability of the evaporation system is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of compression evaporation, and relates to a gas scrubber, in particular to a secondary steam scrubber for an MVR system. Background technique [0002] Mechanical vapor recompression technology (Mechanical Vapor Recompression, referred to as MVR) is a kind of use of the secondary steam and its energy generated by the evaporation system itself to upgrade the low-quality steam into a high-quality steam source through the mechanical work of the compressor. An energy-saving technology that provides heat energy to the evaporation system and reduces the demand for external energy. It has the advantages of good energy saving effect, short product residence time, high degree of automation, simple process, and small engineering investment. It has been widely used in zero discharge of chemical wastewater, organic concentration of sugar alcohol, concentration of pharmaceutical intermediates, and utilization of rectific...
