    How should the grain processing plant choose the type of dust collector to filter light dust


    Grain processing plant dust collectors have stricter requirements than other industries' dust removal equipment. Grain processing plants are directly related to people's food and health issues, so the selection of dust processing equipment in grain processing plants must be serious. Did you choose the right one?

         济南乔泰环保设备有限公司 为食品厂提供各种布袋除尘器,不锈钢布袋除尘器。 Food factory dust collector systems are generally more stringent, because food is closely related to people. Jinan Qiaotai Environmental Protection Equipment Co., Ltd. provides various bag dust collectors and stainless steel bag dust collectors for food factories. Our company has installed a number of grain processing dust collectors in Shanxi. In this respect, we have excellent results and rich experience to solve user's troubles in this regard. 1 、具有独特的喷吹装置,采用柜架拆卸式布袋结构,维修方便; 2 、食品厂除尘器结构紧凑,工艺布置灵活,占地面积小,过滤面积大 ( 单只布袋过滤面积高达 1 平方米 ) ,除尘效率高 ( 99 ) 3 、风机与脉冲组合为一体,简化工艺流程,缩短风网,降低阻力; 4 、采用直角式电磁脉冲阀,需用气源压力低,单气喷量大,用气量小; 5 、广泛适用于粉碎机、下料坑、打包、气力输送中除尘、集中吸风除尘或其它粉尘处理的回收。 Food factory dust collector has the following characteristics: 1. It has a unique spraying device and adopts a rack-mounted detachable bag structure for easy maintenance. 2. The food factory dust collector has a compact structure, flexible process layout, small footprint and large filtration area ( The filtering area of a single cloth bag is up to 1 square meter ) , and the dust removal efficiency is high ( 99 % ) ; 3. The combination of the fan and the pulse simplifies the process, shortens the wind network, and reduces resistance; 4. The right-angle electromagnetic pulse valve requires The pressure of the air source is low, the single gas injection volume is large, and the gas consumption is small; 5. It is widely applicable to the dedusting in the crusher, the unloading pit, the packing, the pneumatic conveying, the centralized suction and dust removal, or the recovery of other dust treatment. 、适用行业:食品行业、化工行业、轻工行业、电子行业等等。 6. Applicable industries: food industry, chemical industry, light industry, electronics industry, etc.

    Grain processing plant selection is particularly important. Customers must provide accurate parameters so that we can choose the right model for you and save you costs.

    Use and maintenance of bag filter in grain factory:

    Timely and effectively solving the faults in the operation of the dust collector can not only ensure the continuity of production, but also prolong the service life of the dust collector. Common failures of the dust collector are as follows:

    The amount of air suction of the dust collector is reduced, and the air suction port cannot effectively capture dust. Causes and solutions:

    ① Duct is blocked and the damper is shifted: clean the duct and fix the damper.

    ② Dust collector and air duct are not tightly sealed. Partial air leakage: Check the tightness of the dust collector and duct.

    ③ The air volume of the dust collector is too small: replace the dust collector.

    ④ Fan does not match: Replace the fan.

    ⑤ The dust bag is blocked:

    ◆ Dust-containing gas concentration is too large, increase pre-filtration or increase dust collector;

    ◆ Excessive humidity of dust-containing gas, heat preservation or heating, replace with water-repellent peritoneal filter material;

    ◆ Dust-containing gas has strong hygroscopicity and adheres to the surface of the filter bag, keeps it warm or heated, and replaces it with peritoneal filter material;

    ◆ The filter bag is used for a long time. Replace the filter bag;

    ◆ The dust cleaning cycle is too long and the spray width is too short. Adjust the pulse controller to shorten the dust cleaning cycle.

    ◆ The filter bag is affected by the gas contained in the blowing gas, and the filter is cleaned;

    ◆ Insufficient dust removal strength, adjust the injection pressure;

    ◆ The pulse controller appears disordered and cannot control dust removal. Check the pulse controller.

    ◆ The solenoid valve does not work, the coil is damaged, the diaphragm is damaged and deformed, the spring is invalid, and it is replaced;

    ◆ The solenoid valve does not work, the setting circuit is wrong, adjust the pulse controller to reset;

    ◆ The shutdown order is not correct. There is no prolonged injection. Adjust the shutdown order according to the specifications and increase the injection delay.

    ◆ Poor ash discharge, excessive accumulation of materials, clean ash bucket, check ash discharge mechanism.

    The dust suction of the dust collector is too large, and the suction port sucks too much dust. Causes and solutions:

    ① Damper shift: Adjust and fix the damper.

    ② The air volume of the dust collector is too large: replace the dust collector.

    ③ Fan does not match: Replace the fan.

    ④ The filter bag is damaged or falling off: Check the filter bag.

    ⑤ The dust accumulation in the filter bag is too small:

    ◆ The cleaning cycle is too short, and the spray width is too wide. Adjust the pulse controller to extend the cleaning cycle.

    ◆ The dust removal intensity is too high, adjust the injection pressure;

    ◆ Dust at the outlet of the dust collector. Causes and solutions:

    a) The filter bag is damaged or shedding: check the filter bag;

    b) The filter bag is not properly sealed: check for reinstallation;

    c) Flower board damage: repair flower board;

    d) The dust particle size is too fine: replace the filter material;

    e) The cleaning cycle is too short and the spray width is too wide. Adjust the pulse controller to extend the cleaning cycle.

    f) The cleaning strength is too strong, adjust the injection pressure.

    Causes and treatment methods of pulse dust cleaning system failure:

    ① No sound can be heard when the solenoid valve is inactive: the coil is damaged, the diaphragm is damaged and deformed, and impurities are stuck on the diaphragm. The diaphragm cannot be reset normally, the spring fails, replace and clean the valve seat.

    ② The solenoid valve does not operate in sequence: the control line is connected incorrectly or broken, check the control line.

    ③Some solenoid valves do not work: the setting circuit is wrong, adjust the pulse controller to reset.

    ④ Pulse controller abnormal damage: repair or replace.

    ⑤ Air bag pressure is too low:

    ◆ The solenoid valve is closed for a long time, and the amount of air released is large. Adjust the pulse controller to reduce the spray width;

    ◆ Insufficient air supply volume, adjust air source;

    ◆ Air leakage between solenoid valve and nozzle, reinstall;

    ◆ Air source processor is blocked, clean the processor;

    ◆ Causes and treatment methods of ash accumulation in dust collector:

    a) The ash discharge is not immediate: adjust the ash discharge frequency;

    b) The ash discharge mechanism is abnormal: repair the ash discharge mechanism;

    c) Air leakage at the ash outlet: check the seal;

    d) Dust accumulation arch: increase the angle of ash discharge, clean up manually or use a vibrator;

    e) High dust and humidity: take thermal insulation measures.
