Cement kiln pure low temperature waste heat generator

Abstract

The invention discloses a cement kiln pure lowtemperature waste heat generator.One end of a preheater is provided with a rotary kiln, one end of the rotary kiln is provided with a cooling machine, oneend of the cooling machine is fixedly connected with a waste gas pipe of a pit head, the middle of the waste gas pipe of the pit head is provided with a settling box, and inclined blocks are arrangedon both sides of the bottom end of the settling box. Bafflesare installed on both sides of the top of the inclined block, and a cellar tail exhaust pipe is fixedly connected with one end of a cellarhead exhaust pipe, and a mixed exhaust pipe is fixedly connected with one end of the cellar tail exhaust pipe, and a generator body is installed at one end of the mixed exhaust pipe. The top of the generator body is provided with a tank body, the inside of the tank body is provided with a steam generating chamber, and the bottom of the tank body is equipped with a dust exhausting bucket. Accordingto the a cement kiln pure lowtemperature waste heat generator, the bottom end of the bafflesareprovided with a plurality of elastic bumpswhich play a certain buffering role and can weaken the impactof waste gas from the pit head containing clinker particles on the baffles in the flow process, is simple and practical, service life of the baffles are prolonged, and later maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of a waste heat power generation device, in particular to a pure low-temperature waste heat power generator for a cement pit. Background technique [0002] In the process of cement production, the pit head and tail of the pit furnace usually contain a large amount of flue gas with low-temperature waste heat. If it is discharged directly without treatment, it will not only cause environmental pollution, but also lead to waste of resources. With the awareness of energy saving Due to the influence of environmental protection and the improvement of the technical level, many enterprises have begun to use these low-temperature waste heat waste gas to generate electricity. Low-temperature waste heat waste gas power generation can not only reduce consumption, save cement production costs, improve economic benefits of enterprises, but also partially alleviate the shortage of electricity consumption and reduce emission...

[0002] In the process of cement production, the pit head and tail of the pit furnace usually contain a large amount of flue gas with low-temperature waste heat. If it is discharged directly without treatment, it will not only cause environmental pollution, but also lead to waste of resources. With the awareness of energy saving Due to the influence of environmental protection and the improvement of the technical level, many enterprises have begun to use these low-temperature waste heat waste gas to generate electricity. Low-temperature waste heat waste gas power generation can not only reduce consumption, save cement production costs, improve economic benefits of enterprises, but also partially alleviate the shortage of electricity consumption and reduce emissions. Smoke temperature and dust concentration avoid environmental pollution. Existing power generation devices usually set up waste heat boilers at the head and tail of the pit, and then mix the hot steam generated by the two together and send it to the steam turbine for power generation. Although this method can reduce some heat loss, the construction cost is high and it is not convenient to manage. In addition, most steam generators generate low steam volume during operation, which is very unfavorable for stable power generation
