Lime kiln industry: Double hearth kiln pulverized coal inject

2016-08-26
Working principle:
Each seat has two double chamber kiln kiln chamber, each chamber kiln 33 injection port. The coal pulverizing system by grinding the powder collecting device for collecting, falling into the coal depot. The pulverized coal injection system of a double hearth kiln, which is a typical Reed company, is located at the bottom of the pulverized coal bunker. The system is mainly composed of a tank blowing, blowing tank outlet is equipped with dual rotary feeder, double rotary feeder is connected to the outlet of the two main line, one of the main pipeline via a pipeline switching valve is divided into 2 lines, each line 16 respectively and the corresponding injection pipe of the kiln chamber by wear resistant hose by 1 1 16 road distributor; another charge of road through the pipeline switching valve is divided into 2 lines, each line 17 respectively and the corresponding injection pipe of the kiln chamber by wear resistant hose connection through the distributor 1 1 17 road; each of the kiln chamber between the work about 12-15 minutes of alternating injection, clearance two of the coal kiln chamber has a reversing time of about 1 minutes, at this time to ensure that the amount of pulverized coal feeding, blowing tank feeding each spray after more than a single coal quantity in each period of the kiln chamber.
System characteristics:
High precision injection; injection continuous, uniform and stable, not because of the pressure of material properties and furnace fluctuations affected; blowing smooth fluctuations, to ensure a stable and reliable material in the pipe conveying system; according to the change of pressure in the pipeline to automatically adjust the feeding quantity, can effectively prevent blockage of pipeline the design of vertical rotary metering valve; the unique structure can ensure the accuracy of the system blowing, without relying on the instrument components and complex control system to complete the overall design; spraying equipment has the advantages of compact structure, less parts, simple operation, action, low failure rate, easy maintenance; injection system injection pressure, the steps for charging and spraying four pressure relief, blowing process, can carry out corresponding actions with the furnace; double rotary feeder under the blowing pump according to the change of furnace conditions are real-time injection quantity adjustment.
