Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] The general phenol ammonia recovery process is as follows: the raw water in the raw water tank enters the top of the tower after being cooled by the cooler 1, and then enters the tower after passing through the preheater 3 5, preheater 2 4, and preheater 1 3. In the upper part, acid gas is produced at the top of the tower, and the crude ammonia produced from the side line in the middle of the tower enters the ammonia recovery system 6 through the preheat...

Abstract

The invention belongs to the technical field of phenol ammonia recovery. The invention further discloses a phenol and ammonia recovery device capable of operating for a long period. The device comprises an acidic water stripping tower and a raw material water tank, wherein one end of the raw material water tank is connected with a cooler I; one end of the cooler I is connected with a preheater III; one end of the preheater III is connected with a preheater II; one end of the preheater II is connected with a preheater I; one end of the preheater I is fixedly connected with the middle upper partof the acidic water stripping tower; the middle part of the acidic water stripping tower is fixedly connected with one side of a preheater II; the ammonia outlet end of the preheater II is connectedwith an ammonia recovery system. The device is compact in structure, wherein the oil enrichment degree in the system can be effectively reduced, so that the purposes of saving energy and improving efficiency can be achieved, the resource utilization rate is greatly increased; meanwhile, transformation on similar devices can be achieved, and the effects of reducing the operation cost of the devicesand improving economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of phenol ammonia recovery, and in particular relates to a long-period operation phenol ammonia recovery device. Background technique [0002] The production of semi-coke uses low-rank coal as raw material, and low-rank coal has a lot of volatile content. During the production process, more organic matter such as tar and phenol oil will be produced, which will eventually enter the semi-coke wastewater. The recovery process of phenol and ammonia is relatively mature, although it can It is used to treat semi-coke wastewater, but due to the serious blockage of the heat exchanger on the ammonia tower and the bottom production pipeline, and the serious corrosion of the gas phase part of the reboiler at the bottom of the solvent recovery tower, it cannot run for a long period of time, which greatly reduces the economical efficiency of the operation. . [0003] In the Chinese patent No. "200910192442.X", a method ...
