Problems solved by technology
[0002] Most coal pyrolysis furnaces (coke ovens) currently on the market adopt batch-type coking. Coke upgrading, dry quenching and other process steps are relatively independent, continuous production cannot be carried out, and production efficiency is low; in addition, the raw coal gas generated during coal pyrolysis contains many useful components, such as H2S , HCH and other acid gases, NH3 basic gas, tar, benzene, naphthalene, washing oil and other organic substances, there is no complete process for exporting, recycling and purifying raw gas

Embodiment Construction
[0023] The specific embodiment of the method for automatically controlling the export and condensation of raw coal gas in a coal pyrolysis furnace according to the present invention is mainly introduced in detail in Sections 1 and 2 of Chapter 1 of the fifth part below.
[0024] Part 1 Furnace Coal Proportion and Preparation
[0025] The coal pyrolysis furnace involved in the present invention can obtain cokes of different grades according to different proportions of coals fed into the furnace.
[0026] The steps are as follows: 1) 5 kinds of different coals are selected, which are respectively gas coal, fat coal, coking coal, one-third coking coal and lean coal. 2) Gas coal 20%~40%; fat coal 10%~20%; coking coal 10%~20%; one-third coking coal 15%~30%; lean coal 10%~15%, first mix and then sieve Broken until the broken particles reach below 5mm to form coal into the furnace. Of course, the coal pyrolysis furnace of the present invention is equally applicable to coal into the ...

The invention discloses an automatic control method for crude gas lead-out and condensation of a coal pyrolyzing furnace. The method mainly relates to a crude gas leading-out device, a crude gas condensing device and an industrial control center. The method comprises the following steps: (1) crude gas generated by coal pyrolysis in a carbonization chamber is led out by the crude gas leading-out device; (2) the led-out crude gas is introduced into the crude gas condensing device to be cooled by spraying ammonia water to form the mixed liquid of the crude gas, coal tar and the ammonia water; and (3) a regulating wheel of the crude gas condensing device is automatically regulated through the industrial control center, and the flow volume of the mixed liquid of the crude gas, the coal tar and the ammonia water is regulated so as to control the pressure of the crude gas in the carbonization chamber. The method has the characteristic that the pressure of the crude gas in the carbonization chamber is automatically controlled so as to realize the control of the coal pyrolysis process, the control precision is good, and the automation efficiency is high.
Description
technical field [0001] The invention relates to an automatic control method for gas export condensation, in particular to an automatic control method for raw coal gas export condensation of a coal pyrolysis furnace. Background technique [0002] At present, most coal pyrolysis furnaces (coke ovens) on the market adopt batch-type coking, and the process steps such as the proportion of coal into the furnace, dehydration, coal feeding, preheating, carbonization, coke reforming, and CDQ are relatively independent and cannot be carried out. Continuous production, low production efficiency; In addition, the raw coal gas produced in the coal pyrolysis process contains many useful components, such as H 2 S, HCH and other acid gases, NH 3 Alkaline gas, tar, benzene, naphthalene, washing oil and other organic substances do not have a complete process for exporting, recovering and purifying raw gas. [0003] This impels the inventors to explore and innovate a complete set of continuo...
