Smoke adsorption system and bituminous mixing plant

Abstract

The invention provides a smoke adsorption system and a bituminous mixing plant. The smoke adsorption system comprises an exhaust pipeline and a suction pipeline, wherein the exhaust pipeline is provided with an air inlet and an air outlet; the air inlet is arranged above a receiving passage of the bituminous mixing plant, and the air outlet is communicated with a main pipeline of a dust removal system of the bituminous mixing plant; a suction device is arranged on the exhaust pipeline and located at the air inlet. According to the smoke adsorption system, the air inlet of the exhaust pipeline is arranged above the receiving passage, the air outlet is communicated with the main pipeline of the dust removal system of the bituminous mixing plant, and the suction device is arranged on the exhaust pipeline and located at the air inlet, so that when waste gas at the receiving passage is adsorbed, the suction device of the air inlet easily absorbs the waste gas inside the receiving passage into the exhaust pipeline through the self power function, and the smoke adsorption effect is remarkably improved. Meanwhile, the power of the suction device is small, energy consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection measures in the production process of asphalt mixing, in particular to a flue gas adsorption system and an asphalt mixing plant with the system. Background technique [0002] At present, as one of the environmental protection measures of the asphalt mixing plant, dust suction pipes are often arranged in the material receiving channel or the mixing layer of the trolley, and the negative pressure of the dust removal system of the asphalt mixing plant is used as the driving force; or an induced draft fan is added as the flue gas. The power source of the adsorption system; this method has the following problems: [0003] 1. Most of the existing flue gas adsorption systems are the power (negative pressure) of asphalt flue gas adsorption drawn from the asphalt dust removal system, and the flue gas adsorption is carried out on the material channel or the stirring layer; however, the flue...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the existing flue gas adsorption systems use asphalt fume adsorption power (negative pressure) from the asphalt dust removal system to absorb the flue gas from the material receiving channel or the stirring layer; Really remove the effect of asphalt fume;

[0004] 2. Or provide a separate induced draft fan or a set of dust removal system. This solution has a better effect of absorbing flue gas, but the power of the induced draft fan is too large (up to 75KW or more), the energy consumption is too large, and the production cost is increased.
