Static-pressure-type pulse main bag filter for collecting carbon black

Abstract

The invention discloses a static-pressure-type pulse main bag filter for collecting carbon black. The filter comprises a plurality of bag filter units, a carbon black flue gas conveying pipeline, a carbon black collecting pipeline, an exhaust gas pipeline, an exhaust gas pressurizing fan and an exhaust gas main pipe; each bag filter unit comprises a conical body, the side edge of each conical bodyis provided with a gas inlet, the lower end of each conical body is provided with a discharging airtight valve, the upper end of each conical body is provided with a box body, the top of the box bodyis provided with an exhaust hole, a pattern plate with a plurality of through holes is arranged between each conical body and the corresponding box body, each box body is internally provided with a plurality of filter bags and compressed air pulse combination rapping units for performing reverse blowing, and the filter bags are arranged at the portions, corresponding to the through holes of the pattern plates, on the pattern plates; each compressed air pulse combination rapping unit comprises a gas blowing pipe corresponding to the filter bags and a solenoid valve for controlling the gas blowing pipe to work, and each solenoid valve is connected with a pulse controller. The static-pressure-type pulse main bag filter for collecting the carbon black has the advantages that the occupied space is small, the operation is convenient, the work energy consumption is low, the efficiency of collecting the carbon black and exhaust gas is high, and the process equipment control is stable.

Description

technical field [0001] The invention relates to the field of dust removal equipment in the technical field of carbon black production, in particular to a static pressure pulse main bag filter for collecting carbon black. Background technique [0002] At present, the collection process after carbon black production is generally a reverse blowing type main bag filter. valve, blowback valve, and blowback blower, and blowback tail gas is provided by a blowback blower. This kind of bag filter blowback device uses blower alone for blowing, adding a blower with a minimum power of more than 50KW, which consumes more power and maintains higher equipment maintenance costs; secondly, the exhaust gas at the inlet of the blower and the inlet of the exhaust pressure fan For the same pipeline, the required operating pressure is relatively high, and the reverse blower and the tail gas pressurization fan alternately pressurize and extract pressure, which will greatly affect the service life...

AI Technical Summary

Problems solved by technology

This kind of bag filter blowback device uses a blower blower alone for blowing, adding a blower blower with a minimum power of 50KW or more, which consumes more power and maintains higher equipment maintenance costs; secondly, the inlet exhaust gas of the blower blower and the exhaust gas pressurization fan inlet For the same pipeline, the required operating pressure is relatively high, and the reverse blower and the tail gas pressurization fan alternately pressurize and extract pressure, which will greatly affect the service life of the filter bag, thereby affecting the collection effect of the filter bag

If the collection effect is reduced, it will lead to large fluctuations in the process parameters of the production equipment
