Abstract

The invention provides a concentrated sulfuric acid pneumatic conveying system which comprises a concentrated sulfuric acid tank truck (8), a concentrated sulfuric acid storage tank (1) and a concentrated sulfuric acid buffer tank (2) which sequentially communicate, and further comprises a vacuumizing device (5), an air buffer tank (3) and an air compressor (6) connected with the air buffer tank (3); the vacuumizing device (5) is connected with the concentrated sulfuric acid storage tank (1) and is used for forming a negative pressure environment in the concentrated sulfuric acid storage tank(1) so that concentrated sulfuric acid is automatically transported to the concentrated sulfuric acid storage tank (1) from the concentrated sulfuric acid tank truck (8); and the air buffer tank (3) is correspondingly connected with the concentrated sulfuric acid storage tank (1) and the concentrated sulfuric acid buffer tank (2) and is used for separately conveying compressed air to the concentrated sulfuric acid storage tank (1) and the concentrated sulfuric acid buffer tank (2) to form a positive pressure environment so that the concentrated sulfuric acid in the concentrated sulfuric acid storage tank (1) flows to the concentrated sulfuric acid buffer tank (2) and the concentrated sulfuric acid in the concentrated sulfuric acid buffer tank (2) flows to an acid distribution point. Automatic and pump-contact-free transportation of concentrated sulfuric acid is realized.

Description

technical field [0001] The present invention generally relates to the technical field of concentrated sulfuric acid transportation, in particular to a concentrated sulfuric acid pneumatic transportation system. Background technique [0002] As a basic chemical, concentrated sulfuric acid is highly corrosive and can corrode all metal products. However, sulfuric acid is widely used, such as chemical plants, metallurgical industry, metal processing, petroleum industry gasoline, lubrication and other departments, so the safe transportation of concentrated sulfuric acid is a crucial process. [0003] At present, the transportation and storage of concentrated sulfuric acid are generally carried by mechanical pumps, and the selection of corrosion-resistant mechanical pumps has become a major technical problem. CN 103723668A invented a concentrated sulfuric acid negative pressure acid unloading system, which relates to the method of transferring concentrated sulfuric acid from a ta...
