1 Introduction to sulfuric acid:
Sulfuric acid is an important chemical industrial product and an important raw material for many industrial production. There are three main types of sulfuric acid produced by Zhuhua Group: 98% H2SO4, 92.5% H2SO4, and 105% fuming sulfuric acid. The pure product is a colorless, odorless, transparent oily liquid that is strongly acidic. It has strong water absorption capacity, can be mixed with water in different proportions, and emits a large amount of heat. It is a strong inorganic acid and is highly corrosive. Chemically very active, almost hydroxide reacts with all metal sulfates and oxides thereof, salts thereof, and also the role of other inorganic acids. When diluting sulfuric acid, only acid can be injected into the water. Do not inject water into the acid to prevent the acid surface from being overheated and causing an explosion. Sulfuric acid with a concentration below 76% reacts with the metal to evolve hydrogen. Sulfuric acid is widely used, mainly in fertilizer, metallurgy, organic synthesis, inorganic salt industry.
2 Production principle and process flow:
2.1 Producing sulfuric acid from elemental sulfur
2.1.1 Production principle
The purity of sulfuric acid is 99.8%-99.9%.
SO2 = SO3 ; SO3 + H2O = H2SO4 + O2
2.1.2 Process
Bottom Support Truck Unloading Platform
XTQC series hydraulic dumper is truck bulk material unloading device that integrates electric and hydraulic control, and is widely used for bulk materials like grain, forage, cement and coke. The equipment improves production efficiency, saves unloading cost, and creates good economic benefit for the user.
Our company starts to design and produce hydraulic dumper since 1990's, and now is the largest manufacturer of that in China, that has the largest market share in China. Our company is the only drafter of national standard of hydraulic dumper GB/T 21489-2008 [Bulk Grain Truck Unloading Device". The product is exported to various countries and areas such as Japan, Vietnam, Malaysia, Thailand and India.
Hydraulic dumper is suitable for automatic unloading of bulk materials like grain, forage, cement and coke, and can be used in industries of chemical, metallurgy, mining, port and coal.
Hydraulic dumper mainly consists of dumping platform, wheel blocking mechanism, main hydraulic oil cylinder, wheel stopper, hydraulic control system, and electric control system.
