Problems solved by technology

[0005] However, on the other hand, the wet electrostatic precipitator in this conventional treatment method has high efficiency, but there are problems due to the adhesion of dust: frequent cleaning is required, frequent failures occur, and the risk of fire is high. unmanageable
[0007] However, due to the rapid development of industry, pollutants have become diversified. In order to treat such pollutants discharged, various types of prevention and control facilities are installed to remove various pollutants. However, due to the increase in prevention and control facilities for removing pollutants The problem that arises is that the installation cost and operating cost of the prevention and control facilities used to remove pollutants are sharply increased, resulting in an increase in the price of the produced product, thereby greatly weakening the competitiveness of the industry.
[0009] However, this technology using expensive products not only increases the production cost but also increases the power cost to cause economic problems, and because of the economic problems, it faces many difficulties in commercialization.

Embodiment 1

[0098] The exhaust gas discharged from the factory that flows into the exhaust pipe 600 flows into the Venturi scrubber 100 through the Venturi inlet 111 to remove pollutants, and then the exhaust gas moves to the connection part 120 through the Venturi exhaust port 114, and along the The calandria connected by 120 move to flow into the multi-stage scrubber 400 . The exhaust gas flowing into the multi-stage scrubber 400 is discharged to the outside after the remaining gaseous pollutants are removed.

Embodiment 2

[0100] The exhaust gas discharged from the factory flowing into the exhaust pipe 600 flows into the Venturi scrubber 100 through the Venturi inlet 111 to remove pollutants, and then the exhaust gas moves to the connection part 120 through the Venturi exhaust port 114, and passes through the connection part 120. The connected cyclone inlet 211 flows into the cyclone scrubber 200 . The exhaust gas from which pollutants have been removed in the cyclone scrubber 200 moves along the exhaust pipe 600 connected to the cyclone exhaust port 214 to flow into the multi-stage scrubber 400 . The exhaust gas flowing into the multi-stage scrubber 400 is discharged to the outside after the remaining gaseous pollutants are removed. This embodiment can be applicable to the situation that the exhaust gas does not contain poorly soluble gaseous substances but only particulate matter.

Embodiment 3

[0102] The exhaust gas discharged from the factory flowing into the exhaust pipe 600 flows into the Venturi scrubber 100 through the Venturi inflow port 111 to remove pollutants, and the exhaust gas moves to the connection part 120 through the Venturi exhaust port 114, and along with the connection part The row pipe 600 connected with 120 moves and flows into the inside of the condensing heat exchanger 300 through the inlet 311 of the condensing heat exchanger to remove pollutants, and then the exhaust gas goes along the row pipe connected to the exhaust port 314 of the condensing heat exchanger Move and flow into the multi-stage scrubber 400. The exhaust gas flowing into the multi-stage scrubber 400 is discharged to the outside after the remaining gaseous pollutants are removed.

Abstract

The present invention relates to an apparatus for treating exhaust gas containing a particulate substance, an insoluble substance, and a gas-phase pollutant. More specifically, the apparatus comprises: a preprocessing device including at least one selected from a scrubber allowing a particulate substance contained in exhaust gas generated in a factory to come in contact with dust collecting water and then be removed and a condensing heat exchanger removing an insoluble substance contained in the exhaust gas using a condensing temperature; and a main processing device including at least one selected from a multi-scrubber removing a gas-phase pollutant remaining in the exhaust gas flowing from the preprocessing device through a gas-liquid contact and an incinerator thermally decomposing and removing a gas-phase pollutant in a heating incineration manner. The apparatus can selectively use the preprocessing device and the main processing device according to the concentration and phase of a substance contained in exhaust gas in order to remove a particulate substance, an insoluble substance, and a gas-phase pollutant contained in the exhaust gas, thereby improving removal efficiency of the pollutant, can minimize the operations of the preprocessing device and the main processing device to reduce production costs and power expenses, thereby solving economical problems and minimizing problems that can occur in the operations after commercialization, and can reducing working hours, thereby improving working efficiency.
