Description
Technical field
The present invention relates to a kind of positive pressure industrial acids to load and unload control system, belongs to chemical industry automatic control technology field.
Background technique
After the sustained and rapid development of national economy, especially China's accession to the WTO, China to the energy and
The demand of chemical products also rapidly increases, this is both the huge market opportunity of prospect for dangerous material storage and transportation industry and tight
High test.Due to having, the more, wire length of point, wide, batch is small, easy tissue, maneuverability and be that other several means of transportation mention
The features such as linking service, road transport has played important function in terms of the Dangerous Goods Transport in China " with China's road
The freight volume of the rapid development of construction, road transport dangerous cargo is increasing, the kind of transport also it is more and more " according to statistics, closely
The annual road transport dangerous cargo in the China Ji Nian is about at 200,000,000 tons or so, wherein hypertoxic Cyanides are just up to 35,400,000 tons, it is inflammable
Explosive oil product class reaches 100,000,000 tons " road transport dangerous cargo oneself cover explosive, gas, easily so liquid, easily so solid, oxygen
The property changed substance, toxicant and infectious substance, nine class of radioactive substance, corrosive substance and miscellaneous dangerous substances and article etc.
Dangerous cargo.
These dangerous material are easy to be influenced by external condition, if in transport, handling, storage since property is active or stabilization is poor
In operation, the effect of the conditions such as photo-thermal, shock, friction is received, explosive combustion, poisoning, burn into radioactive ray spoke just easily occurs
Equal major accidents are penetrated, are caused a tremendous loss of lives, property loss, environmental disruption, bring serious economic loss and not to country
The social influence of benefit.According to external authoritative expert to be related to chemical accident progress investigation result from the point of view of, 41% peril
Belong to shipping accident, shows that shipping accident accounts for suitable specific gravity " currently, the transport of hazardous chemical in counting the accident occurred
Problem has caused the highest attention of road transportation management P department and various circles of society.
Chemicals is the general designation of various chemical elements, the compound and its mixture that are made of element, including natural sum
Artificial " has the hazard properties such as inflammable, explosive, murder by poisoning, burn into radioactivity, in production, storage, transport, use in chemicals
With personal injury, property damage, the category hazardous chemical for polluting environment are be easy to cause during waste treatment etc., it is hazardous
The harm of product mainly includes firing harm, health hazard and environmental hazard.
Oleum is the very high sulfuric acid of concentration, and oleum often refers to storage and transportation problem when practical application, and smoke
Highly volatile goes out sulfur trioxide to sulfuric acid again, and sulfur trioxide is to endanger staff's health to all harmful substance of human body.In opening
The spilling of a large amount of sulfur trioxides is had in system, one is reduction of the service efficiency of raw material oleum, causes to waste, second is that overflowing
Gaseous contamination environment out increases treating tail gas cost.
Sulfuric acid is a kind of strongly corrosion liquid, when loading and unloading sulfuric acid, can be generally divided into positive pressure handling and negative pressure handling.Just
It is handling system more commonly used at present that press fitting, which is unloaded, by being pressed into compressed air, groove tank into the groove tank car Jing Guo encapsulation process
The concentrated sulfuric acid in transport vehicle is extruded by conveyance conduit.Negative pressure handling system extracts the gas in vacuum separation tank using vacuum pump
Body makes to keep certain negative pressure in vacuum separation tank, to extract the concentrated sulfuric acid in groove tank transport vehicle by pipeline.
But the above handling method is all revealed there are concentrated acid and closed not tight problem, the meeting in cargo handling process
The spilling for leading to acid mist threatens to the safety of external environment and site operation personnel, therefore, it is necessary to develop a kind of novel
Industrial acids handling system control system, reduce the leakage of acid mist, reduce the security threat to operator.
