Problems solved by technology

After it breaks, the diammonium hydrogen phosphate catalyst solution will impact the head flange of the mixer, causing corrosion of the head flange, and the diammonium hydrogen phosphate catalyst solution cannot mix with acetic acid steam evenly after the catalyst feeding pipe breaks Phosphoric acid is formed at a high degree, which intensifies the corrosion of the head flange

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0023] Such as figure 1 As shown, a gas-liquid mixer includes a mixer cylinder 6, a first feed pipe 1, a second feed pipe 2 and a catalyst feed pipe 3, wherein the first feed pipe 1 is used to transport acetic acid vapor, The two feed pipes 2 are used to transport the diammonium hydrogen phosphate catalyst solution, and the mixer cylinder 6 is used to mix the two.

[0024] The mixer barrel 6 is fixed to the head flange 8 by a barrel flange 7 arranged on the outer wall of the barrel, and the first feed pipe 1 is fixed at the center of the head flange 8, and the acetic acid vapor passes through the first feed pipe 1 Enter the mixer barrel 6. A second feeding pipe 2 is fixed on the outer wall of the first feeding pipe 1. The second feeding pipe 2 is arranged at a certain inclination angle. A catalyst feeding pipe 3 is provided in the second feeding pipe...

Abstract

The invention relates to a gas-liquid mixer. The gas-liquid mixer comprises a mixer cylinder, a first feeding pipe and a catalyst feeding pipe. One end of the catalyst feeding pipe stretches into the first feeding pipe. The mixer cylinder is provided with a discharge pipe. An adapter bonnet is arranged between the mixer cylinder and the discharge pipe. A support device is fixed to one end of the catalyst feeding pipe stretching into the first feeding pipe. The support device is in a lap joint relationship with the inner wall of the first feeding pipe. The gas-liquid mixer prevents catalyst feeding pipe fracture, effectively prevents catalyst feeding pipe fracture-caused catalyst impact to a cover flange of the mixer, effectively prevents phosphoric acid-caused cover flange corrosion because of poor uniformity of the catalyst mixed with acetic acid steam after catalyst feeding pipe fracture, prolongs a service life of the cover flange and improves mixing effects.

Description

Technical field [0001] The invention relates to a mixer, in particular to a gas-liquid mixer. Background technique [0002] At present, the acetic acid vapor and the diammonium hydrogen phosphate catalyst solution need to use a mixer to achieve the average mixing. One end of the catalyst feeding pipe of the mixer in the prior art extends into the first feeding pipe for feeding. After long-term use, it is found that the catalyst feeding pipe is easy to break. The reason for the fracture is that only one end of the catalyst feeding pipe is fixed, and the end extending into the first feeding pipe is not fixed. The catalyst feeding pipe forms a long cantilever beam, which vibrates and breaks under the impact of the higher flow rate of acetic acid vapor. . After it breaks, the diammonium hydrogen phosphate catalyst solution will impact the head flange of the mixer, causing the head flange to corrode. The diammonium hydrogen phosphate catalyst solution will not be evenly mixed with th...
