Embodiment Construction

[0042] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] Such as Figure 1-2 As shown, a cogeneration system of heat and power includes a waste heat system, a heat exchange system and a heat dissipation system, wherein the heat exchange relationship between the waste heat system and the heat exchange system is carried out through an air-water heat exchanger 6, and the heat exchange system and the heat dissipation system are passed through A heat exchanger 13 is connected for heat exchange.

[0044] figure 1 A kiln waste heat utilization system is shown, the system includes a kiln 1, a main flue 37, a bypass flue 38 and an air-water heat exchanger 6, and the flue gas generated by the kiln passes through the bypass flue inlet 39 After entering the air-water heat exchanger 6, the flue gas after heat exchange flows into the main flue 37 through the outlet 40 of the bypass flue and then is d...

Abstract

The invention provides a furnace waste heat utilization system. The system comprises a furnace kiln, a main gas duct, a bypass gas duct and a gas-water heat exchanger, the gas generated from the furnace enters into the gas-water heat exchanger through the bypass gas duct, the gas subjected to heat exchange flows into the main gas duct through the outlet of the bypass gas duct to discharge, the system further comprises a gas duct temperature sensor, the gas duct temperature sensor is arranged at the lower course of the outlet of the bypass gas duct of the main gas duct, and the gas duct temperature sensor is used for measuring the temperature of the exhaust gas; the system comprises a programmable controller, the programmable controller is in date connection with the temperature sensor, a main gas duct regulating valve and a bypass gas duct regulating valve, and the programmable controller automatically controls the opening of the main gas duct regulating valve and the bypass gas duct regulating valve according to the exhaust gas temperature measured by the temperature sensor. By means of the system, the opening of the gas duct regulating valves can be adjusted intelligently according to the exhaust gas temperature, low-temperature corrosion is avoided, energy sources are saved, and the purposes of environmental protection and energy saving are achieved.

Description

technical field [0001] The invention belongs to the field of waste heat utilization and belongs to the field of F27 kilns. . Background technique [0002] With the rapid development of my country's economy, energy consumption is increasing day by day, and the problem of deteriorating urban air quality is becoming more and more prominent. It is urgent to save energy and reduce the emission of harmful environmental substances. In the common thermal power field, one of the main reasons for high energy consumption and serious pollution is that the exhaust gas temperature of the flue gas is too high, which wastes a lot of energy and causes environmental pollution. The cement industry is a high energy consumption and high pollution industry. The tail gas produced by cement rotary kiln has high dust concentration and poor quality. The waste heat utilization system for cement rotary kiln can recover and reuse the waste heat of tail gas to achieve the purpose of energy saving and ...
