Embodiment Construction

[0019] The method disclosed in the present invention is described in detail below:

[0020] Step 1: Avoid incomplete combustion of coal

[0021] 1.1 Reduce the moisture content of pulverized coal

[0022] By increasing the inlet temperature of the coal mill, the water content of the pulverized coal at the outlet of the mill can be reduced. Under the premise of ensuring the safe production of the coal mill system, the inlet temperature of the coal mill is increased from 350°C to 400°C to 400°C to 450°C. The moisture content of the mill can be reduced to 2.78% (see Table 1).

[0023] 1.2 Reduce the fineness of pulverized coal

[0024] Through the operation and adjustment of the coal grinding system, the fineness of pulverized coal can be reduced. For example, increase the speed of the separator, close the damper of the main exhaust fan of the coal mill, and adjust the ball distribution of the mill to reduce the fineness of the coal powder. After adjustment, the fineness of ...

Abstract

The invention relates to a method for preventing material blockage of a cyclone cylinder of a preheating tower of a cement kiln. The method comprises the following steps that firstly, incomplete combustion of coal is avoided; secondly, clinker overburning is avoided; thirdly, leaking stoppage operation is carried out on site; fourthly, clearing is carried out on site. According to the method for preventing material blockage of the cyclone cylinder of the preheating tower of the cement kiln, the step design is scientific and reasonable, material blockage of the cyclone cylinder of the preheating tower of the cement kiln can be effectively prevented, and cement process kiln stopping accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of maintenance of cement production equipment, in particular to a method for preventing material blocking of a cyclone cylinder of a preheating tower of a cement kiln. Background technique [0002] In the process of cement production, the phenomenon of material blocking in the cyclone of the preheating tower of the cement kiln often occurs, which greatly affects the normal production process of the cement. In severe cases, it will lead to the kiln shutdown accident of the cement process and cause great property losses to the cement production plant. loss. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a method for preventing the clogging of the cyclone of the cement kiln preheating tower. [0004] Technical effect of the present invention is realized through the following technical solutions: [0005] A method for prevent...
