Fault coal upgrading material cooler

Abstract

The invention discloses a fault coal upgrading material cooler which comprises a rotating barrel, a slag feeding box is arranged at the front end of the rotating barrel, a slag discharging box is arranged at the rear end, the rotating barrel is of a film wall structure, and a plurality of material pushing plates are arranged on the film wall in a spiral mode. The front end and the rear end of a film wall fin water pipe on the film wall are connected with a front annual collecting box and a rear annual collecting box respectively. A water inlet main pipe and a water outlet main pipe are arranged on the axis of the rotating barrel. The water inlet main pipe sleeves the water outlet main pipe, and the water inlet main pipe and the water outlet main pipe are connected with a water feeding and discharging device. The water outlet main pipe is communicated with the front portion of the rotating barrel and connected with the front annual collecting box through a water outlet elbow. The rear annual collecting box is connected with the water inlet main pipe through a water distributing pipe. By means of exchange of radiation heat and conduction heat between materials and the rotating barrel, heat exchanging coefficient is high. The cooler reduces the material temperature, waste heat is fully absorbed through cooling water, recycling of the waste heat is achieved, and the requirement of saving energy and reducing consumption is met.

Description

technical field [0001] The invention belongs to material heat exchange and cooling equipment, in particular to a material cooling equipment for upgrading low-quality coal (such as bituminous coal and lignite) in the coal chemical industry. Background technique [0002] Because there are a large amount of low-quality coal stored in our country, in order to make full use of these low-quality coals, ensure their purity requirements during use and reduce their environmental pollution, it is necessary to upgrade these low-quality coals. However, due to the requirements of the treatment process, the temperature of the low-quality coal after upgrading is relatively high, which can reach 300-600 ° C, and the operation is extremely dangerous. High-temperature materials are not convenient for direct transportation and storage. If they are allowed to cool naturally, the cooling speed will be slow, air pollution will occur to the surrounding environment of the materials, affect the indo...

AI Technical Summary

Problems solved by technology

High-temperature materials are not convenient for direct transportation and storage. If they are allowed to cool naturally, the cooling speed will be slow, and there will be air pollution to the surrounding environment of the materials, affecting the indoor temperature of the material stacking workshop, and there will be energy waste at the same time.

[0003] The existing upgrading coal material cooling equipment mainly relies on the heat dissipation between the surface of the high-temperature material and the air to reduce the temperature of the material when the high-temperature material is conveyed by the scraper machine. Lost in the atmosphere causing heat pollution
