Description

COMPLETE SPECIFICATION**[*See* section 10 and rule 13]# **"DROPLET SEPARATOR"**Name and Address of the Applicant:Name: **MUNTERS EUROFORM GMBH**Nationality: **Germany**Address: **Philipsstr. 8, 52068 Aachen, Germany**## **PREAMBLE OF THE DESCRIPTION**The following specification particularly describes the invention and the manner in which it is 25 to be performed.### **DESCRIPTION**The present invention relates to a separation device in a gas stream channel, and a flue gas cleaning system having a separation device according to the invention.Separation devices of the generic type, in particular such separation devices that have separator 5 levels with rod or respectively tube-shaped separator elements arranged parallel to each other, are frequently used in flue gas cleaning systems, in particular in flue gas desulfurization systems. Before a treatment of the flue gases with the separation device, the flue gas is cleaned in a flue gas cleaning system, normally in a wet washing method, in particular to remove sulfur dioxide (SO2) from the flue gas. The cleaned gas is then conducted into the separation device 10 in order to remove remaining particles and droplets from the gas stream following a wet washing in the gas stream. Typically, separation devices of the generic type are arranged in a vertical gas stream oriented from a bottom to the top so that the particles and droplets collecting on the separator elements can drop or respectively rain down following gravity against the gas flow. With an orientation of the separator levels that is suitably oblique or respectively inclined 15 downward in a vertical direction, the liquid can flow along the separator elements of the separator levels, following gravity downward, and continue to rain downward in a strand. Below the separation device, the falling or downwardly flowing particles and droplets are normally collected in a so-called scrubber sump.The particles in the separation process, in particular adhering to the separator elements, 20 frequently cause contamination of the separation device. It is therefore normally provided to apply a rinsing liquid to the device, in particular the separator levels, at regular cleaning intervals. This discontinuous application of liquid is typically performed during ongoing operation, i.e., while the gas stream is flowing through the separation device. Provided that the flow speed of the treated gas between the separator elements is sufficiently low, the liquid 25 thereby accumulating on the separator elements can rain or respectively flow down and is captured in the scrubber sump.To separate very small particles, for example in the range of less than 15 µm, a liquid can be applied to at least some separator elements or respectively separator levels, including continuously. The application of the liquid is normally performed by nozzles to achieve a continuous wetting of the separator elements and thereby promote efficient cleaning or respectively particle separation.Separation devices for removing particles and droplets from a gas flow are for example known from DE 102006004723 A1, WO 1996024429 A1 and WO 2007104284 A2.5 In the separation of very small particle sizes, and in particular at high speeds between the separator elements at which the so-called flooding point of the separator stage is reached or respectively exceeded, it may occur that the liquid film running off the separator elements is prevented from running off by the gas flow, and larger droplets are detached from the liquid film by the gas flow and transported upward in the direction of the outlet of the separation 10 device. This mode of operation can result in a failure of the overall separation device.The object of the present invention is to provide a separation device of the initially describe type which can even be efficiently operated when a separator element, given a vertical gas flow, is at the flooding point or above.The object is achieved by a separation device having the features of claim 1. Advantageous 15 embodiments are specified in the dependent claims.The invention is based on the concept of guiding raining liquid droplets against the direction of flow of the gas to be treated along inclined arranged separator elements, and collecting them in a collection basin arranged in the flow channel. From there, the liquid can be drained in a controlled matter in a scrubber or respectively in a scrubber sump.20 A separation device is in accordance with the invention for separating droplets and particles from a gas stream having a directional component facing upward in a substantially vertical direction, wherein the separation device contains at least one separator stage that comprises at least one separator layer having a plurality of elongated separator elements arranged parallel to each other, and wherein the separator elements of the at least one separator stage are arranged 25 inclined in their longitudinal orientation relative to the horizontal dire
