Autoclave, also known as autoclave, is a large pressure vessel with large volume and large weight that is widely used. It is widely used in the autoclave curing of aerated concrete blocks, gray sand bricks, coal ash bricks, microporous calcium silicate panels, new lightweight wall materials, insulation asbestos panels, concrete pipe piles, ALC panels, high-strength gypsum and other building materials. Autoclave is mainly to obtain high strength after the material is steamed in the kettle (the hydrothermal reaction of CAO-SiO2-H2O is completed in the kettle). Its application can cover the chemical industry, medicine, aerospace industry, insulation materials, spinning, rubber products, wood drying, anti-corrosion treatment, heavy metal smelting, refractory brick oil and coal penetration, glass steaming, chemical fiber products high pressure treatment, food high temperature and high pressure treatment, pulp cooking, cable vulcanization, fishing net shaping and other pressure steaming process production. The advantages of this kind of products are environmental protection, energy saving, safety and can improve the efficiency of production products.
The working pressure of autoclave is generally 1.3MPa and 1.5MPa, which is a low and medium pressure vessel, but its volume is large, the product of pressure and volume is large and belongs to the pressure vessel with explosion, which belongs to the class I, II and III pressure vessels according to the "Fixed pressure vessel safety Technical Supervision Regulations" category.
Autoclave is a large pressure vessel with large volume and heavy weight. It is composed of kettle body, kettle cover, flange, support, valve instrument and safety accessories, and is laid with rail and steam distribution pipe. The cover of the kettle is pressed by Q345R, and the kettle body is rolled by Q345R, and the flaw detection is carried out one weld by one. Autoclave flanges are divided into autoclave body flanges and kettle cover flanges, which are forged by 16MnII as a whole. After CNC processing, the whole heat treatment is adopted to eliminate forging stress and welding stress, and ultrasonic non-destructive testing is carried out one by one, and secondary finishing is carried out to fully ensure that the kettle door switch is light and flexible. Rail steel Carbon steel 55Q (12kg/m, 15kg/m, 22kg/m, 30kg/m). Equipped with perfect manual and automatic safety interlocking device to ensure the autoclave operation and operation safety.
Autoclave according to the overall structure is divided into: end type, through type.
According to the opening mode of the kettle cover, it is divided into side door type and upper door type.
The way of opening the kettle cover is divided into: manual door opening, electric door opening, hydraulic door opening, pneumatic type.
The working medium is saturated water vapor.
The autoclave with a diameter below 2.25m has a working pressure of 1.3MPa, a design pressure of 1.4MPa, a working temperature of 195.0℃ and a design temperature of 198.3℃.
The autoclave with a diameter of more than 2.5 meters has a working pressure of 1.5MPa, a design pressure of 1.6MPa, and a working temperature of 201.4℃ and a design temperature of 204.3℃
