Embodiment 1

[0044] Embodiment 1: When only a single storage tank 1 needs to be prepared:

[0045] Close the control valve 12 on the low-pressure steam pipe 4, the process water pipe 5 and the concentrated sulfuric acid pipe 6 connected to one of the two storage tanks 1. At this time, only one of the two storage tanks 1 can be used for infusion preparation. The main valve 10 on the low-pressure steam pipe 4, the process water pipe 5 and the concentrated sulfuric acid pipe 6, the concentrated sulfuric acid and the process water are input into the storage tank 1 together. During the transportation, the low-pressure steam pipe 4 transports the steam to the tail section of the steam pipe 11. The tail section 11 of the steam pipe is inserted into the storage tank 1. Since the four steam pipe tail sections 11 are evenly distributed along the circumference of the storage tank 1, and the angle between the elbow 103 and the tangent line of the circumference is 18°, the steam is transported to After...

Embodiment 2

[0046] Embodiment 2: When it is necessary to prepare two storage tanks 1 at the same time:

[0047]Simultaneously open all operating valves 12 on the operating platform 7, open the main valve 10 on the low-pressure steam pipe 4, the process water pipe 5 and the concentrated sulfuric acid pipe 6, the concentrated sulfuric acid and the process water are input in the two storage tanks 1 together, and are transported During the process, the low-pressure steam pipe 4 transports the steam to the tail section 11 of the steam pipe. The angle between the tangents of the circumference is 18°. After the steam is transported into the storage tank 1, it will form a swirling flow after being output through the elbow 103, and the process water and concentrated sulfuric acid in the storage tank 1 will be stirred and kept warm. During the preparation process, the flow meter 8 and the pneumatic valve 9 installed on the operation platform 7 can be used to monitor the process water, concentrated ...

Abstract

The invention discloses a steam-driven phosphoric acid system cleaning fluid preparation device with the temperature control linkage function. The device comprises a storage tank. An output pipeline is mounted at the bottom end of the storage tank; an output pump is mounted at the tail end of the output pipeline; a concentrated sulfuric acid pipe and a process water pipe are respectively inserted at the top end of the storage tank; a plurality of low-pressure steam pipes are also inserted at the top end of the storage tank; the tail ends of the low-pressure steam pipes are connected with a steam pipe tail section; the steam pipe tail section comprises a pipe body which is vertically arranged and is inserted into the storage tank; the top end of the pipe body is fixedly connected with a flange; the bottom end of the pipe body is fixedly connected with an elbow perpendicular to the pipe body; main valves are mounted on all of the concentrated sulfuric acid pipe, the process water pipe and the low-pressure steam pipes. The steam-driven phosphoric acid system cleaning fluid preparation device with the temperature control linkage function can effectively solve the problems of an existing cleaning fluid preparation device and also has the advantages of low cost, low manual labor intensity, good controllability, durability and the like.

Description

technical field [0001] The invention relates to the technical field of phosphoric acid production, in particular to the cleaning field of phosphoric acid production equipment, and in particular to a steam-driven phosphoric acid system cleaning solution preparation device with temperature control interlocking. Background technique [0002] In the process of phosphoric acid production, it is generally necessary to use a cleaning solution preparation device. The cleaning solution preparation device is mainly composed of storage tanks and auxiliary pipelines, valves, stirring devices, and delivery equipment (pumps), which is an indispensable link in the phosphoric acid production process. , whether the operation of the device is good or not is directly related to the normal operation of the phosphoric acid delivery pipeline, which seriously affects the production efficiency of phosphoric acid. Existing cleaning liquid preparation device such as Figure 1-2 As shown, the storage ...
