摘要:
A high temperature gas containing sulfur oxides is desulfurized by converting sulfur oxides to ammonium compounds by the injection of ammonia and irradiation with an electron beam. The high temperature gas containing the sulfur oxides is cooled by contacting the gas with recirculated cooling water, then mixed with ammonia, air, and water and irradiated with an electron beam.

The present invention relates to a method and an apparatus for producing a fertilizer by injecting ammonia into and applying electron beam to gas containing sulfur oxides. Gas containing sulfur oxides is cooled by a heat exchanger (2) and a cooling tower (3), and thereafter introduced into a process vessel (4) in which ammonia is injected into the gas and the gas is irradiated with electron beam. The product of the ratio of the concentration of ammonia to the concentration of water in the gas prior to irradiation of the electron beam and the ratio of the concentration of ammonia to the concentration of water in the gas after irradiation of the electron beam is controlled to be of a predetermined value.
摘要:
A method and apparatus for treating gas by irradiation with an electron beam. Flue gas discharged from a fuel combustion facility is treated with an electron beam to remove sulfur oxides and/or nitrogen oxides. Ammonia is added to the flue gas and the mixed gas is irradiated with an electron beam in a process vessel. A dust collector receives the gas and collects a by-product mainly composed of ammonium sulfate and/or ammonium nitrate which is produced by the reaction in the process vessel. A gas-contacting portion extending from the process vessel to the dust collector is cooled either wholly or partly, to a dew point of the gas or below.

A process for desulfurization and denitration of waste gas by multi-stage electron beam irradiation and an apparatus used for the process are constituted so that the waste gas is passed through the electron beam irradiation zones in multiple irradiation chambers that are arranged in such a way that the center-to-center distance (m) between two neighboring electron beam generators is not shorter than distance X calculated by the formula, X=2.alpha.+tV wherein 2.alpha. means distance over which an absorbed dose extends into a waster gas, t means a residence time (sec.) of waste gas in a non-irradiation zone, and V stands for the flow velocity of waste gas, whereby t can be reduced to 0.01-0.5 seconds, so that irradiated energy can be utilized efficiently and a maximum effect can be obtained with a minimum expenditure of irradiation energy. Therefore, the waste gas can be treated rapidly and economically.

摘要:
The present invention relates to an electron beam-irradiating reaction apparatus for irradiating a desired object to be treated, such as an exhaust gas, with an electron beam. Conventionally, a scanning tube of an electron beam irradiation device and a reaction device-for receiving the electron beam are rigidly connected. Therefore, excessive stress is applied to a connecting portion between the scanning tube and the reaction device and not only leakage of gas from the connecting portion, but also breakage of a metal window foil provided at an end portion of the scanning tube are likely to occur. In the present invention, to solve such problems, a flexible hermetic sealing member 23 is provided between a portion around the end portion of the scanning tube 12 and a peripheral edge 18a of an electron beam receiving window in a side wall of an electron beam reaction device 18.
