Problems solved by technology

Although the steam condensate pressure and temperature adjustment device disclosed in this patent document can digest and absorb the steam pressure in time, the device is huge and complicated, occupies a large area, and the cost performance is obviously unreasonable, which increases the economic burden of the enterprise.
Moreover, the equipment only condenses and adjusts the pressure of the steam, and cannot absorb and separate harmful gases and impurities in the steam

Abstract

The invention relates to a multi-step steam pressure digestion absorber and application thereof. The multi-step steam pressure digestion absorber comprises a digestion absorber body, an air inlet pipe, a distribution head, a first electric valve, a first branch steam pipe, a first digester, a second electric valve, a second branch steam pipe, a second digester, a third electric valve, a third branch steam pipe, a third digester and a pressure meter. The multi-step steam pressure digestion absorber solves the problems that instant pressure is high and vapor emission of a rotary spherical digester is blocked due to the fact that the rotary spherical digester in a steaming system is large in vapor emission speed and high in pressure. Moreover, the vapor emission time of the rotary spherical digester is shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to a multi-step steam pressure digestion absorber and its application, belonging to the technical field of steam equipment. Background technique [0002] In the pulping section of papermaking and chemical fiber enterprises, after cooking, during the discharge of cooking waste steam, the initial pressure is high, the speed is fast, and the final pressure is low. During the production process, it is difficult to control the stable pressure and discharge of waste steam, which brings great difficulties to the absorption of waste steam emission. During the recovery process of cooking waste steam, if the waste steam discharged from the steaming ball cannot be digested and absorbed in time, the cooking quality and production efficiency will be affected. [0003] Chinese patent document CN101280914A provides a steam condensate pressure and temperature regulating device, including: an expansion vessel, a cooler and a pressure regulating v...
