Embodiment Construction

[0043] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] 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.

[0045] 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 multiuser-oriented automatic measuring and controlling energy-saving kiln waste heat utilization system. The multiuser-oriented automatic measuring and controlling energy-saving kiln waste heat utilization system comprises a kiln, a main flue, a bypass flue and a gas and water heat exchanger. Flue gas generated by the kiln enters the gas and water heat exchanger through an inlet of the bypass flue, and after heat exchange, the flue gas flows in the main flue through an outlet of the bypass flue and then is discharged. A controller can automatically control heat supply to a user according to a set condition. According to the multiuser-oriented automatic measuring and controlling energy-saving kiln waste heat utilization system, automatic control over supply of heat can be achieved, the maximization of heat exchange efficiency is achieved, energy resources are saved, and therefore 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 emi...
