Description

A double-row single-spray cleaning device for high-temperature resistant filter bags

technical field

The invention relates to a cleaning device for high-temperature-resistant filter bags, which belongs to the field of textile machinery, in particular to a double-row single-spray cleaning device for high-temperature-resistant filter bags, which is particularly suitable for cleaning high-temperature-resistant filter bags.

Background technique

High temperature resistant filter bags can effectively control the emission of smoke (powder) and dust in high temperature flue gas, and are widely used in many industrial production fields such as electric power, cement, steel, and waste incineration. However, the used filter bags will produce hard-to-degrade solid waste, which has a greater potential impact on the environment. On the one hand, the degradation cycle of the filter bag itself is very long, and it takes decades for the above-mentioned solid waste to degrade in the natural state. On the other hand, after the filter bag is landfilled, the harmful substances in the dust will enter the surface water circulation system, resulting in greater harm. This kind of harmful treatment has greatly damaged the living environment of human beings, and made my country's future economic and social sustainable development face severe challenges. After the high temperature resistant filter bag is used, after cleaning, repairing and other treatments, it can still be used if the technical indicators such as strength and ventilation meet the working conditions. At present, the recycling and reuse of high-temperature resistant filter bags is still relatively small, and it is in the stage of exploration and development. In the future, as the country's environmental protection requirements increase, the requirements for atmospheric environmental protection and air pollutant control will be higher. Not only must the emission of dust be strictly controlled, but also all industries that produce high-temperature flue gas will be required to control the existing ones that have not reached the national standard. Dust removal equipment is updated to reduce the dust concentration in high-temperature flue gas, avoid air pollution, and control air pollution from the source. This provides a very broad space for the market development of high-temperature resistant filter bags, so the recycling of high-temperature resistant filter bags Utilization will also receive unprecedented attention. Cleaning equipment is the key equipment to realize the recycling and reuse of filter bags. The Chinese invention patent application publication number CN 103331052 B, the title of the invention is "a filter bag cleaning device", which discloses a filter bag cleaning device, which includes a cleaning water tank and a The water pump connected to the cleaning water tank, wherein: the cleaning water tank includes at least one cleaning unit, and each cleaning unit is equipped with an inner flushing pipe, an outer flushing pipe and a turntable bracket for supporting the filter bag, and the inner flushing pipe extends into the filter bag The inner and outer flushing pipes are located outside the filter bag, and both the inner flushing pipe and the outer flushing pipe are connected to the water pump, and the turntable bracket can rotate under the action of the water pressure of the inner flushing pipe and the outer flushing pipe. The patent relies on the impact force of water to impact the filter bag to drive the turntable. There are two problems. One is that the impact force is too large, which will damage the surface of the filter bag, and it is not suitable for high-temperature resistant filter bags processed by nonwovens. The power is small, which may easily cause the cleaning around the filter bag to be unclean or uneven; secondly, due to the rotation of the turntable, the energy of separation and stripping of the dust on the surface of the filter bag by water is reduced, and the cleaning effect is not good.

To sum up, when recycling and reusing existing high-temperature resistant filter bags, there is a lack of cleaning devices that do not damage the surface structure of the filter bags, have good cleaning effects, and have high cleaning efficiency.
