Problems solved by technology

[0004] Due to the complex composition of domestic waste, the heat source of incineration comes from the waste heat of cement kiln and garbage combustion. The heat source is unstable and easy to block materials. The fluctuation of cement production process and unexpected shutdown will affect waste incineration, and even cause accidents such as burning outside the waste furnace and causing fires.

Embodiment Construction

[0019] An automatic control method for incinerator feed, including a feed push rod control system and a feed gate valve control system, when the feed gate valve control system controls the feed gate valve to open, the feed push rod control system controls the feed push rod Reciprocating push material, adjust the reciprocating operation time interval of the feed push rod according to the amount of incoming material at the feed port of the incinerator and the temperature and pressure of the incinerator, set the time interval t of the feed push rod action, and the running speed of the feed belt V, The temperature of the incinerator is T, the pressure is P, k 1 ,K 2 is the proportional coefficient, the push rod movement interval time can be expressed by formula (1):

[0020] (1)

[0021] to combine figure 1 The feed push rod is composed of a push rod, a hydraulic cylinder, a push head, and a push head guide rail. When working, the hydraulic cylinder drives the push rod to co...

Abstract

The invention provides an automatic control method for feeding of an incinerator. A feeding push rod of the incinerator is automatically controlled in a reciprocating manner so as to control the amount of fed materials.

Description

technical field [0001] The invention relates to the technical field of garbage incineration, in particular to an automatic control method for co-processing domestic garbage incinerator feed in a cement kiln. Background technique [0002] With the advancement of the urbanization process, a large number of people have entered the city life, and the generation of domestic waste is also increasing day by day. Traditional landfill treatment not only takes up a lot of arable land, but also easily pollutes water sources and air. How to realize the harmless and resourceful treatment of garbage is an urgent task that our country is currently facing. Cement production is a process of high energy consumption and high pollution. At present, my country's cement production ranks first in the world, accounting for about 40% of the world's production capacity. Large and small cement factories are spread all over the country, consuming a huge amount of resources. [0003] Using cement kil...
