Description

Technical Field

[0001] This invention relates to the field of environmental protection machinery technology, and in particular to a corrosion-resistant, high-efficiency electrostatic dust absorption device. Background Technology

[0002] Chemical plants generate large amounts of dust during product processing. This dust contains numerous corrosive impurities and pollutes the atmosphere. To prevent dust pollution, advanced environmental protection equipment is required during dust emission. Among these equipment are highly efficient electrostatic dust absorption devices. These devices are corrosion-resistant and absorb dust into their interiors for purification. The purified dust is then discharged, and finally, the purified impurities are collected and cleaned.

[0003] According to CN201710746371.8, this invention relates to an environmental protection device for absorbing airborne dust, belonging to the field of airborne dust treatment technology. It includes a first dust removal chamber, a second dust removal chamber, an inlet pipe, an outlet pipe, a sewage pipe, a sewage discharge device, a spray device, an absorption layer, an electrostatic dust removal device, a coarse filter, a connecting pipe, a water injection pipe, a first fan, and a second fan. This invention features multi-stage absorption, progressively removing dust layer by layer; simultaneously, the device also has an automatic sewage discharge function, changing the manual method of sludge cleaning and achieving a high degree of automation.

[0004] However, existing dust absorption devices generally discharge impurities through a pipe structure. The pipe is fixed to the lower side of the device. When collecting impurities, a collection cart or collection bag is required. Due to the different heights of the collected items, as well as positioning deviations, a reliable seal cannot be formed between the end of the pipe and the inlet of the collected items. This causes dust to splash during the fall of gravity, resulting in secondary dust pollution and affecting the working environment. At the same time, when discharging impurities, the staff needs to adjust the collected items and control the valve switch, which is quite cumbersome. Summary of the Invention

[0005] In view of this, the present invention provides a corrosion-resistant and high-efficiency electrostatic dust absorption device, which has the function of adjusting the position of the discharge port so that the discharge port moves to the position of the collection vehicle or dust collection bag to discharge impurities, reducing the dust discharged from impurities, avoiding the problem of dust flying everywhere and affecting the environment, and improving the environmental cleanliness during the impurity cleaning process.

[0015] Beneficial effects

[0016] This invention employs a lifting and cleaning mechanism to place an atmospheric pollution absorption device that absorbs dust into the device. After dust purification, impurities flow to the lower side of the absorption body for cleaning. During impurity cleaning, a collection cart or dust collection bag is placed below the discharge port. The lifting motor drives the discharge port to slide, adjusting the discharge port's position to move it relative to the collection cart or dust collection bag. This reduces the height difference between the discharge port and the dust collection bag, improving the reliable seal between them. This reduces dust emissions, preventing dust from spreading and affecting the environment, and enhancing environmental cleanliness during impurity cleaning. The discharge port is replaceable, allowing for the use of different shaped discharge ports for various situations, facilitating convenient impurity collection.

[0017] In addition, by adopting a discharge switch mechanism, when impurities are collected, the discharge port moves to the lower side and drives the baffle to slide. The baffle slides open, allowing impurities to flow out from inside the absorption body. This avoids the problem of staff having to operate the valve separately to control whether impurities are discharged, saving staff time and making it easier for staff to use the absorption device.
