Leak hunting method of carbonyl iron synthetic kettle

Abstract

The invention discloses a leak hunting method of a carbonyl iron synthetic kettle and relates to improvement of the leak hunting method of a synthetic kettle applicable to carbonyl iron production. The leak hunting method is characterized in that a fixed air pipe is arranged on a big sealing cap of the carbonyl iron synthetic kettle and penetrates the big sealing cap; during leak hunting, leak hunting medium air is led into a sealing chamber, composed of a sealing plug of the synthetic kettle and the big sealing cap, through the fixed air pipe until that a preset test pressure is achieved, then enclosed pressurizing is performed, and according to pressure changes of the synthetic kettle and the sealing chamber which is composed of the sealing plug of the synthetic kettle and the big sealing cap, the carbonyl iron synthetic kettle is subjected to leak hunting judgment. The leak hunting method has the advantages that by the aid of few leak hunting medium, leak hunting and leak source processing are performed on middle-pressure large and medium reaction vessels within short time, production efficiency is improved, running time of a large high-pressure air compressor is shortened, and power consumption is decreased.

Description

technical field [0001] A leak detection method for a carbonyl iron synthesis kettle relates to an improvement of a leak detection method for a carbonyl iron synthesis kettle. technical background [0002] In the production process of carbonyl iron, leak detection must be carried out before the synthesis kettle is loaded. According to the public information, the leakage detection of the carbonyl iron synthesis kettle uses the leak detection medium to enter the synthesis kettle body from the CO inlet port, and gradually rises according to the pressure vessel regulations. Pressurize to the specified pressure (9Mpa), and carry out leak detection on the large sealing cover of the synthesis kettle in different pressure sections. power consumption. Leakage handling process is complicated, and production organization efficiency is low. Contents of the invention [0003] The object of the present invention is to address the deficiencies in the above-mentioned prior art, and provi...

[0002] In the production process of carbonyl iron, leak detection must be carried out before the synthesis kettle is loaded. According to the public information, the leak detection of the carbonyl iron synthesis kettle uses the leak detection medium to enter the synthesis kettle body from the CO inlet port, and gradually rises according to the pressure vessel regulations. Pressurize to the specified pressure (9Mpa), and carry out leak detection on the sealed cover of the synthesis kettle in different pressure sections. It takes a long time (about 2 hours) for the process of boosting and releasing the pressure to deal with the leak, and the operation of a large gas compressor also requires power consumption
