Desulfurization and dust removal device based on rotary spraying and spiral gas-liquid separation principle

Abstract

The invention discloses a desulfurization and dust removal device based on a rotary spraying and spiral gas-liquid separation principle. The desulfurization and dust removal device comprises a devicecasing and supporting columns, wherein a rotating shaft is arranged at the lower part of the device casing and is connected with the output end of a driving motor; the driving motor is fixedly arranged at the lower side of the device casing; a hollow inner cavity is arranged inside the rotating shaft; a gas outlet plate is arranged at the lower side of the device casing; a first spraying pipe anda second spraying pipe are arranged in the device casing; a plurality of atomizing spray heads are uniformly arranged on the second spraying pipe; the first spraying pipe and the second spraying pipeare both connected with a water storage tank through a liquid draining pipe; a gas-liquid separating device is arranged above the first spraying pipe and comprises a base; a filter bag, an antibacterial filter layer and an activated carbon filter layer are arranged above the base; the supporting columns are fixedly arranged at the bottom of the device casing; damping devices are arranged on the corresponding supporting columns. According to the desulfurization and dust removal device disclosed by the invention, by using a rotary spraying method and arranging a striking plate, waste gases makefull contact with a lime solution and the treatment effect of the waste gases is effectively improved.

Description

technical field [0001] The invention relates to the technical field of desulfurization and dust removal, in particular to a desulfurization and dust removal device based on the principles of rotary spraying and spiral gas-liquid separation. Background technique [0002] As my country's main primary energy source, coal occupies a large proportion of energy consumption in power plants, boilers and coking industries. Especially this year, with the development of my country's economy, the increase in energy demand has greatly increased the consumption of coal. consume. When coal is burned, sulfur dioxide will be produced. For the coking industry, the carbonization chamber of the coke oven is heated by the gas heating vertical fire channel to provide the heat source. The waste gas generated after the gas heating contains more sulfur dioxide and particulate matter. If these waste gases are discharged directly, this is harmful to the air. The pollution is extremely serious. Especi...

Problems solved by technology

Especially in most urban and rural enterprises in our country, coal combustion is used for production. These production and processing enterprises are mainly small workshop enterprises. High maintenance intensity, thus abandoning the waste gas treatment and directly discharging it into the air, causing environmental pollution. So many small enterprises in the country directly discharge coal-fired waste gas, which is inestimable to the environmental pollution
