Description
Technical Field
The utility model belongs to air entrainment board production evaporates pressure cauldron waste heat utilization field, concretely relates to evaporate pressure cauldron waste heat utilization system of air entrainment board production.
Background
The aerated slab is a high-performance light slab which is prepared by taking lime, cement, silica sand and the like as raw materials, adding and stirring the raw materials according to a formula, pouring a reinforcing mesh with a specific structure for forming, precuring and cutting the reinforcing mesh, and finally curing the reinforcing mesh with high-pressure steam. However, China's aerated concrete production enterprises are always energy-consuming households in the building material industry, and how to reasonably utilize resources in the aerated concrete production enterprises is an urgent problem to be solved, namely, the steam heating system of the still kettle has low efficiency and serious waste of water resources and energy resources, wherein the lack of scientific utilization of condensed water is a main reason for energy waste.
In the use process of the still kettle, a large amount of high-temperature steam needs to be continuously supplemented, in the actual production, in order to ensure the steam curing effect of the gas filling plate, the work of the still kettle is changed in stages, the air pressure in the kettle is changed therewith, condensate water discharged from the still kettle comprises high-temperature condensate water and medium-temperature condensate water, the temperature of the high-temperature condensate water reaches about 100 ℃, and the temperature of the medium-temperature condensate water reaches 60-70 ℃. The traditional autoclave condensed water is not completely recycled. Some enterprises directly discharge the condensed water into a base tank or an open water collecting tank of the still kettle, the condensed water is directly subjected to flash evaporation after entering the base tank, and heat conduction and air radiation are carried out through the tank wall, so that the heat of the condensed water is almost lost; the condensed water is discharged into the water collecting tank through a pipeline, so that flash evaporation loss also exists, and the lost heat reaches more than 70% of the discharged heat of the condensed water in the autoclave.
And in the production process of the aerated plate, the following steps are carried out: the processes of pre-curing, standing still, paint dipping, drying and the like all need heat assistance, and usually adopt electric heating. But the electric heating not only consumes a large amount of electric energy and increases the cost, but also has more potential safety hazards in the use process, and the equipment is inconvenient to overhaul and replace. Therefore, waste heat of the still kettle is wasted, and the gas filling plate needs a large amount of electric energy for heat supply, so that the production mode is unreasonable, and the requirements of low consumption, high yield and green production are not met.
Chinese patent No. CN 110715286a proposes a system for recovering heat energy from an autoclave and a boiler, which includes an autoclave and a boiler for supplying steam to the autoclave, and further includes a gas-water heat exchanger and a water-water heat exchanger, where the gas-water heat exchanger includes a gas flow path for heat exchange and temperature reduction and a water flow path for heat exchange and temperature rise, and the water-water heat exchanger includes a water flow path two for heat exchange and temperature reduction and a water flow path three for heat exchange and temperature rise; residual steam discharged by the still kettle and steam generated by boiler surface pollution discharge are communicated with a primary side inlet pipe a, a secondary side inlet pipe a is communicated with boiler feed water, and a secondary side outlet pipe is communicated with a boiler; condensed water discharged by the still kettle and high-temperature hot water generated by blowdown at the bottom of the boiler are communicated with a primary side inlet pipe b, a secondary side inlet pipe b is communicated with boiler feed water, and a secondary side outlet pipe b is communicated with the boiler. The device discharges the comdenstion water to the boiler, recycles through the boiler heating, because comdenstion water is self-brought the heat, has reduced the power consumption cost of heating in the steam curing cauldron application.
However, the device only recovers the condensed water and heats and utilizes the condensed water, and still has the problems that part of heat energy is lost and the heat generated by the condensed water is not fully utilized.
