Description
技术领域technical field
本发明涉及布袋除尘器技术领域，具体为一种带有辅助震动结构的布袋除尘器。The invention relates to the technical field of bag dust collectors, in particular to a bag dust collector with an auxiliary vibration structure.
背景技术Background technique
布袋除尘器是一种干式滤尘装置，它适用于捕集细小、干燥、非纤维性粉尘，滤袋采用纺织的滤布或非纺织的毡制成，利用纤维织物的过滤作用对含尘气体进行过滤，当含尘气体进入布袋除尘器后，颗粒大、比重大的粉尘，由于重力的作用沉降下来，落入灰斗，含有较细小粉尘的气体在通过滤料时，粉尘被阻留，使气体得到净化，但它在实际使用中仍存在以下弊端：The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and the filter function of the fiber fabric is used to filter the dusty gas. After filtering, when the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust will be retained. The gas is purified, but it still has the following disadvantages in actual use:
1、滤料使用一段时间后，由于筛滤、碰撞、滞留、扩散、静电等效应，滤袋表面积聚了一层粉尘，随着粉尘在滤料表面的积聚，除尘器的效率和阻力都相应的增加，当滤料两侧的压力差很大时，会把有些已附着在滤料上的细小尘粒挤压过去，使除尘器效率下降；1. After the filter material has been used for a period of time, a layer of dust accumulates on the surface of the filter bag due to effects such as screening, collision, retention, diffusion, and static electricity. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector are corresponding. When the pressure difference on both sides of the filter material is large, some fine dust particles that have attached to the filter material will be squeezed out, which will reduce the efficiency of the dust collector;
2、传统的布袋除尘器对滤袋的固定方式较为简单，长期使用后，容易导致滤袋的松动甚至滑落；2. The traditional bag filter fixes the filter bag in a relatively simple way. After long-term use, it is easy to cause the filter bag to loosen or even slip;
3、传统的布袋除尘器仅仅进行除尘工作，然后将除尘后的空气直接排入到外部大气中，但布袋除尘器内的空气往往带有一些硫性物质，直接排出会给大气造成二次污染。3. The traditional bag filter only performs dust removal work, and then directly discharges the air after dust removal into the external atmosphere, but the air in the bag filter often contains some sulfur substances, and direct discharge will cause secondary pollution to the atmosphere .

工作原理：使用时，带有粉尘的空气从布袋除尘器本体1的进气口进入，然后在布袋除尘器本体1顶部抽风机10的吸附下向上流动，一部分粉尘通过通风口21时被吸附在滤袋36的内壁上，然后气体继续上升经文丘里管32后粉尘被隔离在文丘里管32的下侧，气体经过滤板31过滤后通过抽风机10的出气口排出，吸附在滤袋36内壁的粉尘，在震动装置8击打除尘装置3的过程中，落入到粉尘收集仓9内，当击打块84与除尘装置3接触时，在弹簧83的压缩作用下收缩到变形槽82内部。Working principle: When in use, the air with dust enters from the air inlet of the bag filter body 1, and then flows upwards under the adsorption of the exhaust fan 10 on the top of the bag filter body 1, and a part of the dust is absorbed in the air outlet 21 when passing through the bag filter body 1. On the inner wall of the filter bag 36, then the gas continues to rise through the Venturi tube 32, and the dust is isolated on the lower side of the Venturi tube 32. After the gas is filtered by the filter plate 31, it is discharged through the outlet of the exhaust fan 10 and adsorbed on the filter bag 36. The dust on the inner wall falls into the dust collection chamber 9 when the vibrating device 8 hits the dust removal device 3, and when the beating block 84 contacts the dust removal device 3, it shrinks into the deformation groove 82 under the compression of the spring 83 internal.
