Technical Field
The utility model belongs to the technical field of the dust material shifts transshipment equipment, specifically a buggy conveying equipment.
Background
The dust content of the flue gas discharged in the dry cement production process is large, the components are complex, and the nitrogen oxides have the greatest harm to human bodies and seriously pollute the environment. The domestic common denitration mode is that denitration in the furnace and denitration outside the furnace are combined to reduce the content of nitrogen oxide in flue gas to the maximum extent, but the measures are all that a burner is arranged at the tail end of a kiln, a reduction reactor is arranged at the tail end of a flue gas pipeline, and the like, so that a large amount of cost and energy consumption support are still needed. Therefore, a technical solution to the current situation is needed to provide a cost-effective and energy-efficient method for removing the pin.
The hot carbon catalytic reduction technology is produced in continuous research and exploration, and the principle is as follows: the air at the kiln head is driven by high-temperature airflow to flow to the kiln tail, low-oxygen air is formed in the kiln tail, coal powder is added into the kiln tail, the coal powder is insufficiently combusted at the kiln tail to produce carbon monoxide depending on the high-temperature and oxygen-deficient environment of the kiln tail, the carbon monoxide reacts with nitrogen oxides at the kiln tail to produce carbon dioxide and nitrogen dioxide, and the denitration in the kiln is completed. And the denitration process is an exothermic reaction and heats the material at the tail of the kiln.
The hot carbon catalytic reduction technology needs to send ground coal dust into an overhead rotary kiln, and in the process, high-pressure gas needs to be used for driving the coal dust to enter a kiln tail, so that the coal dust is easy to harden in a coal dust bin, and the problem of unsmooth coal feeding is caused. The common coal hardening prevention mode is that the pulverized coal bin is manually and periodically vibrated to enable pulverized coal to slide, which not only wastes labor and time, but also easily causes structural damage to the pulverized coal bin.
In addition, the pulverized coal is quantitatively weighed on the ground and then is sent into the kiln through a high-pressure air pipe. However, in the actual pulverized coal blowing process, a certain gap exists between the weighing device and the pulverized coal bin, and when high-pressure air is blown, a part of pulverized coal can flow back into the pulverized coal bin from the gap, so that the amount of pulverized coal fed into the kiln has errors, and the denitration effect is influenced.
