Embodiment Construction
[0013] The embodiment of the present invention intends to use 400°C high-temperature flue gas heat to implement power generation and heating of factory buildings, so as to realize cascaded utilization of energy. Such as figure 1 As shown, during the winter heating period, part of the high-temperature flue gas (400°C) discharged from the flue 1 of the glass tunnel kiln enters the heat exchanger 2 to release part of the heat, and the temperature of the flue gas drops to 50°C. The temperature of the cooling water rises from the original 40°C to 45°C. The heated water enters the heating coil 3 buried under the floor, heats the entire floor, and radiates heat to the room through the ground evenly, thereby heating the factory building 4 . The other part of the high-temperature flue gas discharged from the flue 1 of the glass tunnel kiln enters the evaporator 5 of the low-temperature generating set, and the heat is taken away by the power generation medium, and the high-temperature ...

Provided are a device and a method for power generation and heating by using waste heat produced by quartz glass. The method is characterized in that in the heating period, one part of high temperature flue gases discharged by a glass tunnel kiln enters a heat exchanger, and partial heat is transferred to cooling water and enters a coil pipe arranged below a factory building floor after temperature rising to perform heating for factory buildings, the other part of high temperature flue gases enters an evaporator of a lower temperature generator set to transmit heat to power generation media, the power generation media enter an expander of the generator set to do work and drive a generator to generate power, low voltage power generation media after doing work enters a condenser for condensing and heat emission, and heated cooling water is sent to a cooling tower to be recycled after being cooled; and in the non-heating period, the temperature flue gases discharged by the glass tunnel kiln totally enter the lower temperature generator set to be converted to electricity to be output, accordingly zero energy consumption of the factory buildings is achieved and environment pollution and heat pollution are reduced.
Description
technical field [0001] The invention relates to a device and method for recycling industrial waste heat by using low-temperature double-cycle power generation and floor radiant heating, in particular to a device and method for recycling and utilizing waste heat gas discharged from a glass tunnel kiln for power generation and heating, which is applied in the production process of quartz glass. A device and a method for realizing zero energy consumption of factory buildings. Background technique [0002] Energy and environmental issues have become the primary issues facing countries all over the world. Energy shortages and environmental pollution caused by energy consumption have become an important obstacle restricting global economic growth and social progress. With the rapid development of the national economy, my country has become the world's second largest energy consumer, and the problem of energy shortage is becoming more and more serious. Industrial waste heat resour...
