Problems solved by technology

But its shortcomings are also obvious. One is that the heating method is bottom heating, which is contrary to the horizontal heating method of coke ovens produced by coking enterprises; the other is that it can only carry out constant pressure coking and cannot carry out variable pressure coking

Embodiment 1

[0036] A method for pressure-variable coking using a small single-hole pressure-variable coking device, comprising the following methods:

[0037] 1) Start the control system, the coke oven starts to heat up, and the coke oven body reaches 1000°C within 2 hours;

[0038] 2) Weigh 2kg coal sample, put the coal sample into the coke oven body, close the furnace door, insert the connecting rod into the casing on the furnace door, and connect the other end of the connecting rod with the cylinder piston;

[0039] 3) Start the hydraulic adjustment system and adjust the hydraulic pressure in the cylinder to the set pressure: 0.2Mpa, which remains unchanged;

[0040] 4) Real-time detection of the coal sample temperature in the coke oven and the hydraulic pressure in the oil cylinder, when the coal sample temperature reaches 800℃, adjust the hydraulic pressure in the oil cylinder to the set pressure: 2.0Mpa;

[0041] 5) Real-time detection of the coal sample temperature in the coke ove...

Abstract

A small single-hole pressure swing coking device and a pressure swing coking method, the device includes a coke oven, a hydraulic adjustment system, an upright baffle, and an oil cylinder, the oil cylinder is fixed on the upright baffle, and the oil cylinder is installed on the coke oven door. Press the coal sample in the coke oven through the furnace door to exert pressure on the coal sample. The coke oven is equipped with a heating device, and the hydraulic adjustment system adjusts the pressure of the oil cylinder. Compared with the existing technology, the beneficial effects of the present invention are: 1) Change the internal pressure of the coke oven through the hydraulic adjustment system, so that the pressure in the whole process of coking can be changed, and the coke quality and expansion pressure can be better obtained through multiple sets of experimental data The relationship between them, and then predict the optimal expansion pressure that is most suitable for coking, and increase the correlation and credibility of the data; 2) Adopt a double-sided heating method that is more in line with the actual situation of industrial production, so that the heating is uniform and the quality of coke is improved. The measured test data is also more accurate.

Description

technical field [0001] The invention relates to an experimental coking device and method, in particular to a small single-hole pressure swing coking device and a pressure swing coking method. Background technique [0002] Coke is mainly used in blast furnace ironmaking and blast furnace smelting for non-ferrous metals such as copper, lead, zinc, titanium, antimony, and mercury. Higher and higher. However, due to the serious waste of resources and environmental pollution caused by coking at the same time, the resources of coke are increasingly tense, and the pressure of the coke industry is doubled. Therefore, optimizing the coking process, improving the quality of coke, saving coking resources, and reducing the cost of raw materials have become urgent problems for enterprises to solve. [0003] The coal loading capacity of traditional experimental coke oven ranges from 2Kg to 200Kg, and there are various specifications, which can realize conventional coking or tamping coki...
