摘要:
An electrostatically enhanced separator (EES) which provides mechanical separation and electrostatic separation to yield a compact and highly efficient separation system. The EES (10) may be incorporated in a collection system as well using a conventional collection device such as a cyclone collector (32), bag filter (37) or electrostatic precipitator (38). The EES (10) includes a cylindrical-walled separation chamber (11) with an inlet passage (13), a clean flow outlet (21), and a particle outlet passage (15). The inlet passage (13) and particle outlet passage (15) are both thin elongated slits which open tangentially to the cylindrical wall of the chamber for providing a substantially flush incoming flow path dispersed lengthwise along the wall.

An improved combined power generation cycle has been provided for electric power generation from gasified solid fuel such as coal or biomass. The power cycle provided by the present invention does not require the use of high-temperature particulate control systems or wet clean-up systems. A high-temperature high-pressure gas stream is first cooled in a heat-transfer system and then cooled again by any one of a variety of methods before the particulate solids and hazardous air pollutants are removed in a low-temperature dry solids collector. Then, the clean gas is reheated in the same heat-transfer system and is ready for use in power generation. Net plant efficiencies can be improved by injecting water or steam upstream of the topping cycle power generating means.

A combination reaction chamber and gas/solids separator is provided in a common reactor vessel. The reactor is capable of carrying out various types of gas/solids reactions within the reaction chamber and, contemporaneously, separates the gas from the particulate solids by way of a separator disposed within the reaction chamber. Gas exits the reaction chamber through an outlet disposed along a central axis of the chamber. Solids exit the chamber through an outlet disposed along the outer periphery of the chamber. The reactor provides improved mass transfer rates as well as selective residence times.
摘要:
A device separates particulates from a gas stream flowing through the device. The device includes at least one high voltage electrode and a substantially cylindrical separator. The high voltage electrode applies a first voltage to the gas stream. The separator has an inlet for introducing the gas stream into the separator tangentially to an interior wall of the separator, a particulate outlet for expelling the particulates from the separator, and a gas stream outlet.
摘要:
An emission treatment system includes a first separation device that is operable to introduce one or more sorbents into an exhaust stream having emission products. The sorbent captures the emission products such that the exhaust stream includes sorbent with captured emission products. A second separation device located downstream from the first separation device receives the exhaust stream and utilizes an electrostatic potential to separate the sorbent with captured emission products from the exhaust stream into a discharge stream to produce a clean stream.

摘要:
An emission treatment system includes a separation device having a vessel that includes an inlet for receiving an emission stream having entrained solid particles. A first outlet from the vessel discharges captured solid particles from the emission stream and a second outlet from the vessel discharges a clean stream having fewer entrained solid particles than the emission stream received into the separation device. A particle collector is fluidly connected with the separation device and includes a collection portion for capturing solid particles from the emission stream.
