Steam purification and recovery device

Abstract

The invention discloses a steam purification and recovery device. According to the technical scheme, the steam purification and recovery device is characterized by comprising a barrel; an air inlet hole, an air outlet hole and a pollution discharge hole are formed in the barrel; and a coarse purification assembly and a fine purification assembly are arranged in the barrel. The coarse purification assembly comprises two limiting plates and a silk screen layer, the two limiting plates are arranged in a spaced mode and fixed to the inner side wall of the barrel; a plurality of vent holes allowing high-temperature steam to pass through are formed in the limiting plates correspondingly; and the silk screen layer is limited between the two limiting plates. The fine purification assembly comprises a filter element fixing plate and a plurality of filter element pipes, wherein the filter element fixing plate is used for fixing the filter element pipes and dividing the interior of the barrel into two parts which can only be communicated through the filter element pipes; and the ends, close to the coarse purification assembly, of the filter element pipes are closed, and openings are formed in the other ends of the filter element pipes. The device can purify high-temperature steam mixed with impurities, and is high in purification efficiency, good in purification effect and low in filter element maintenance cost.

Description

technical field [0001] The invention relates to the field of high-temperature steam purification, and more specifically relates to a steam purification recovery device. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. In order to control the boiler steam quality, the boiler is designed with continuous blowdown (also known as surface blowdown), that is, the boiler continuously discharges part of the boiler water from the part with the highest salinity concentration of the boiler water, so as to reduce the salt content, alkali content and The amount of dross in suspension. Its purpose is to ensure the quality of boiler water so that the boiler can operate stably and safely for a long time, and the heat loss from blowdown is also one of the im...

Problems solved by technology

Currently on the market, the high-temperature steam mixed with impurities is purified by a large filter element that only allows high-temperature steam to pass through and blocks the passage of impurities. The purification efficiency is low and the service life of the large filter element is short. The large filter element needs to be replaced frequently, resulting in high maintenance costs for the large filter element.
