Dead steam recycling device of spray type deaerator

Abstract

The invention discloses a dead steam recycling device of a spray type deaerator, and aims to overcome the defects of a complex structure, incapability of completely eradicating exhausted steam and thelike in the prior art. The device comprises a closed container; an upper water seal is arranged on the upper middle portion in the container; a water seal water inlet and a water seal water discharging port are formed in the side wall of the upper middle portion of the container; the upper water seal divides the interior of the container into an upper space and a lower space; an emptying openingis formed in the top of the container in the upper layer space; a deaerator dead steam condensation space is arranged in the lower layer space; a deaerator dead steam pipe is at the center of the condensation space; the dead steam pipe downwards penetrates out of the container; a dead steam inlet is formed in the bottom of the dead steam pipe; a heat insulation sleeve is arranged outside the portion, located in the container, of the dead steam pipe; an annular water chamber is arranged below the upper water seal along the periphery of the inner wall of the container; a water inlet is formed inthe side wall of the portion, in the position of the water chamber, of the container; a lower water seal is arranged between the heat insulation sleeve and the inner wall of the container below the water chamber; and a drain pipe is arranged below the lower water seal on the lower portion of the side surface of the container.

Description

Technical field[0001]The invention belongs to the technical field of deaerator exhaust steam recovery, and particularly relates to a spray-type deaerator exhaust steam recovery device, which is suitable for thermal deaerators in thermal systems of various industries.Background technique[0002]The thermal deaerator exhausts the dissolved oxygen in the water and part of the steam at the same time due to the process requirements. Therefore, the exhaust steam of the deaerator is a source of steam and water loss in the thermal system. At the same time, the exhaust steam of the deaerator is accompanied by certain noise; the dispersion of steam in the atmosphere causes the surrounding working environment to be poor.[0003]In order to solve this problem, the Chinese Patent Publication No. CN206073746U discloses a deaerator exhaust steam recovery device, which includes a shell, a number of serpentine coils, a water inlet pipe and a water outlet pipe; one end of the shell is provided with In th...
