Description

Automation of evaporating still cauldron steam pouring economizer system

Technical Field

The utility model relates to an evaporate automatic economizer system that falls of pressure cauldron belongs to the energy-conserving field of steam.

Background

The autoclave is widely applied to the autoclave curing of concrete blocks, pipes, piles, rods, sleepers, sand-lime bricks, coal-lime bricks, microporous calcium silicate boards, heat-insulating asbestos boards, high-strength gypsum and other building materials so as to meet the requirements of construction and building. Meanwhile, the method is also widely applied to production process processes requiring pressure steam curing, such as rubber products, wood drying and antiseptic treatment, oil-impregnated and coal-impregnated refractory bricks, composite glass steam curing, high-pressure treatment of chemical fiber products, high-temperature and high-pressure treatment of food cans, pulp steam cooking, cable vulcanization and the like. Taking aerated concrete as an example, the autoclave is required to be decompressed and cooled after the aerated bricks are subjected to heat preservation and autoclaving through steam. In the pressure relief and temperature reduction process, although most of enterprises carry out steam reversing recycling on steam discharged during pressure relief at present and are used for primary temperature rise of other still kettles, the manual operation is complicated, and steam pressure for steam reversing and recycling is high, and steam with high pressure is still discharged outside, so that great energy waste is caused. In addition, the steam source contains large water or the steam is superheated steam, which influences the steam-pressing effect and efficiency of the aerated bricks. The utility model discloses an exhaust steam when high-efficient recycle pressure release cooling reduces steam consumption, energy saving and emission reduction by a wide margin. Meanwhile, the steam pressure effect and efficiency are improved by optimizing the steam source.
