Problems solved by technology

[0004] At present, the widely used deaerator is the membrane deaerator, but the membrane deaerator is composed of an external deaerator head and a water tank. The water tank has a complex structure, large volume, poor operating performance, and requires a large installation space. Manufacturing and installation costs are relatively high; the core oxygen removal components in the oxygen removal head are fixed and cannot be disassembled, making maintenance difficult and poor operation stability

Abstract

The invention discloses an internal type headless high-pressure deaerator. The internal type headless high-pressure deaerator comprises a barrel body, wherein an internal barrel body, a water-spraying inner barrel, a re-boiler, a steam mixing outer barrel, a heating steam tube, a re-boiling heating tube and a deaerated water outlet are mounted inside the barrel body; a water feeding tube, a water return tube and a gas exhaust tube are arranged on a barrel body surrounded by the internal barrel body; and a spraying device and a filler layer are further arranged inside the internal barrel body from top to bottom. The invention further provides a deaeration method which separates oxygen in water through a tertiary device. Compared with a conventional system with a deaeration head, the internal type headless high-pressure deaerator has the beneficial effects of reducing equipment height, greatly reducing civil engineering cost, reducing lift of a water inlet pump, achieving the energy-saving effect, being more complete in deaeration, and being capable of achieving effect of 0.05 ppm, and being applicable when a steam temperature ranges from 104 DEG C to 190 DEG C. The internal type headless high-pressure deaerator is simple and compact in structure, and is convenient to mount and maintain.

Description

technical field [0001] The invention relates to the field of tire high-pressure water deaeration, in particular to a built-in headless high-pressure deaerator and a deaeration method. Background technique [0002] In the vulcanization system used in the vulcanization workshop of the tire factory, the temperature and pressure of hot water are relatively high. The general temperature is 170-180°C and the pressure is 2.1-2.8MPa, which is called superheated water in the industry. Harmful gases such as oxygen and carbon dioxide are often dissolved in superheated water. Under high temperature and high pressure, dissolved oxygen has a great oxidation effect on vulcanization equipment, especially on the bladder in the inner cavity of the tire in the vulcanizer, which shortens the life of the bladder. [0003] Deoxygenation by superheated water will slow down the oxidative chain scission reaction and prolong the service life of the capsule. Practice has proved that with the applicat...
