Description

Technical Field

[0001] This utility model relates to the technical field of asphalt production equipment, and in particular to a high-efficiency cyclone dust removal device for asphalt production. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt production requires heating and stirring of the raw materials, which generates large amounts of dusty fumes. Direct release of these fumes into the atmosphere would cause severe air pollution.

[0003] Therefore, the generated dusty flue gas needs to be treated for dust removal. In the existing technology, cyclone dust collectors or bag dust collectors are usually used to remove dust from the flue gas. After a period of use, the dust removal efficiency of the dust collector will decrease, and the staff will need to stop the machine for maintenance.

[0004] The existing technology has at least the following problems: First, the production efficiency of asphalt will be affected when the cyclone dust collector is cleaned and maintained; second, the dust-laden flue gas not only contains large dust particles, but also a variety of volatile organic compounds, and direct emission will easily form fine particulate matter, polluting the atmosphere. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a high-efficiency cyclone dust collector for asphalt production. This invention allows for cleaning and maintenance of the dust collector without shutting down the machine, and it can also adsorb volatile organic compounds in the gas, effectively improving the production efficiency of asphalt and reducing environmental pollution.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a high-efficiency cyclone dust removal device for asphalt production, including an air inlet main pipe, a dust removal system and an exhaust main pipe, and also including a purification system. The dust removal system is connected to the purification system through an air supply pipe. The dust removal system includes several sets of parallel cyclone dust collectors. The air inlet of the cyclone dust collector is connected to the air inlet main pipe through a first air inlet branch pipe. The exhaust port of the cyclone dust collector is connected to the air supply pipe through a first exhaust branch pipe. The exhaust port of the purification system is connected to the exhaust main pipe.

[0007] As an optimization, the purification system includes several sets of parallel purification adsorption boxes. The air inlet of each purification adsorption box is connected to the gas supply pipe via a second air inlet branch pipe, and the exhaust port of each purification adsorption box is connected to the main exhaust pipe via a second exhaust branch pipe. By setting up the purification adsorption boxes, organic waste gas in the flue gas can be adsorbed and further dust removed. By setting up the second air inlet branch pipe and the second exhaust branch pipe, the sets of purification adsorption boxes can be connected in parallel, allowing them to work alternately to adsorb volatile organic compounds, achieving uninterrupted production.

[0008] As an optimization, a first intake valve is provided on the first intake branch pipe, and a first exhaust valve is provided on the first exhaust branch pipe. By setting the first intake valve and the first exhaust valve, when they are open, a cyclone dust collector can be selected for use, so that the cyclone dust collector is connected to the intake main pipe and the air delivery pipe for dust removal; when they are closed, the cyclone dust collector can be cleaned and maintained.

[0009] As an optimization, a second intake valve is provided on the second intake branch pipe, and a second exhaust valve is provided on the second exhaust branch pipe. By setting the second intake valve and the second exhaust valve, the purification adsorption box can be selected for use when it is open, so that the purification adsorption box is connected to the gas supply pipe and the exhaust main pipe to purify volatile organic compounds in the gas; when closed, the purification adsorption box can be cleaned and maintained.

[0010] As an optimization, the purification adsorption box is equipped with activated carbon adsorbent, which can efficiently adsorb volatile organic compounds in the gas.

[0011] As an optimization, fans are installed on the intake manifold, the gas delivery manifold, and the exhaust manifold. By installing fans, the gas delivery capacity can be improved, and the gas pressure in the pipeline can be maintained.

[0012] As an optimization, the cyclone dust collector is equipped with a dust hopper at the bottom. By setting up the dust hopper, dust particles can be collected and disposed of uniformly.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting up an intake manifold, dust-laden flue gas can be transported to the dust removal system for dust removal. By setting up a first intake branch pipe, a cyclone dust collector, and a first exhaust branch pipe, the various cyclone dust collectors can be connected in parallel and work alternately for dust removal, achieving uninterrupted production. By setting up a gas delivery pipe, the dust-removed gas can be sent to a purification system for volatile organic compound (VOC) adsorption and purification. The purification system can adsorb VOCs in the gas. This utility model can both clean and maintain the dust removal device without stopping the machine and adsorb VOCs in the gas, effectively improving the production efficiency of asphalt and reducing environmental pollution.

[0020] The purification system includes several sets of parallel purification adsorption boxes 7. The air inlet of the purification adsorption box 7 is connected to the air supply pipe 5 through a second air inlet branch pipe 6, and the exhaust port of the purification adsorption box 7 is connected to the exhaust main pipe 9 through a second exhaust branch pipe 8. By setting up the purification adsorption boxes 7, organic waste gas in the flue gas can be adsorbed and further dust removed; by setting up the second air inlet branch pipe 6 and the second exhaust branch pipe 8, the sets of purification adsorption boxes 7 can be connected in parallel and can work alternately to adsorb volatile organic compounds, realizing uninterrupted production.

[0024] The bottom of the cyclone dust collector 3 is equipped with a dust hopper 15. By setting up the dust hopper 15, dust particles can be collected and cleaned uniformly.

[0025] In operation, dusty flue gas enters a set of cyclone dust collectors 3 through the main inlet pipe 1 and the second inlet branch pipe 6 for dust removal. After dust removal, the gas enters a set of purification adsorption boxes 7 through the first exhaust branch pipe 4, the gas delivery pipe 5, and the second inlet branch pipe 6. The activated carbon in the purification adsorption box 7 adsorbs volatile organic compounds in the gas and further filters the gas.
