Title:
MEMBRANE METHOD PROCESSING SYSTEM AND PROCESS FOR HIGH-CONCENTRATION SALT-CONTAINING ORGANIC WASTE LIQUID INCINERATION EXHAUST GAS
Document Type and Number:
WIPO Patent Application WO/2019/019759
Kind Code:
A1
Abstract:
A membrane method processing system and process for a high-concentration salt-containing organic waste liquid incineration exhaust gas; the system consists of a waste liquid incinerator (I), a gas-solid separator (II), a heat exchanger (III), an air blower (IV), an anti-caking agent storage tank (V), a membrane method dust cleaner (VI), an induced draft fan (VII), a check valve (VIII), and a desulfurization tower (IX). The membrane method dust cleaner (VI) comprises: a temperature and humidity sensor (1), an anti-caking agent nozzle (2), a membrane method dust cleaner inlet (3), a dust removal membrane (4), an embossed plate (5), an ash bucket (6) ), a middle box body (7), an upper box body (8), a heat-retention heating device (9), and a reverse spraying and blowing device (10). The process comprises: a high-temperature high-concentration dust-containing gas (a) that is discharged from the waste liquid incinerator (I) entering the gas-solid separator (II); the high-temperature dust-containing gas (b) in which part of the dust is separated entering the heat exchanger (III) for heat exchange; the dust-containing gas (c) after heat exchange entering the membrane method dust cleaner (VI) for dust removal; the temperature and humidity sensor (1) detecting the dust-containing gas that enters the membrane method dust cleaner inlet (3); the dust-free gas (d) that is purified by means of the membrane method dust cleaner (VI) entering the desulfurization tower (IX) by means of the check valve for desulfurization, and then being discharged. The system introduces the dust removal membrane (4) into an exhaust gas processing system, which may prevent inorganic salts from accumulating and agglomerating inside the dust cleaner (VI).
