Abstract

The invention discloses a high temperature dust collector cyclone which belongs to a technical field of a dust collector. The dust collector cyclone comprises a housing, wherein, an air inlet and an air outlet are arranged on the housing, the bottom part of the housing is provided with a lower part ashpit, the bottom part of the ashpit is an ash discharge opening, a rotational flow chamber is arranged in the housing, the downstream of the rotational flow chamber is provided with a flow guide device, and the downstream of the flow guide device and the upper part of the ashpit are provided with internal ash falling devices. A water-cooling system is arranged in the housing; the inner wall of the housing is provided with a heat-resistance and wear-resistance inside lining. The device has the advantages of high temperature resistance, being able to carry out dust removing on the gases containing dust under the temperature less than 1000 DEG C, wear-resistance, long service life and good dust removing effect.

Description

Technical field [0001] The invention relates to a dust remover for removing dust from coal gas with high airflow temperature and much dust, in particular to a high-temperature cyclone dust remover. Background technique [0002] Cyclone dust collector is a large category of industrial dust removal equipment, widely used in chemical, petroleum, metallurgy, construction, mining, machinery, textile and other industrial sectors. [0003] In the metallurgical industry, gravity dust collectors or ordinary cyclone dust collectors are usually used in the traditional ironmaking process for crude gas dust removal. The components of the dust collector are generally made of carbon steel, and the interior is sprayed with wear-resistant and heat-insulating linings. The allowable gas temperature generally does not exceed 250. ~300℃. If the temperature of the dust-containing gas to be processed is too high, and the subsequent process system also requires high-temperature and clean gas, this kind ...
