During the vaporizer of the air admission dehumidifying device that (1) regain is bigger, heat is absorbed by refrigerant, is cooled to predefined temperature of saturation.Because temperature reduces, water recovery contained in the air becomes drop, and most of water droplet is separated out because of action of gravity, still is mixed in the air but a part of diameter is about the condensing drip of 5～20 μ m, has reduced the dehumidification effect.
(2) from the undecomposed condensing drip entrained air of vaporizer; Get into blower inlet compression work done; Make dehumidifying machine as virtual work cause the dehumidification ability drop, negative can the dehumidification effect descend, the gas blower operational efficiency reduces, and influence that conditions of blast furnace is stable, energy-conservation, the protection of raising the output and blower vane.
Summary of the invention
The purpose of the utility model provides a kind of effective blast furnace blast systems for moisture removal water of condensation catcher device.This device mainly solves following problem:
(1) realization is caught the condensing drip that diameter in the systems for moisture removal is about 5～20 μ m, reduces blower inlet air regain, and through the automatic drain system recycling.
(2) after process was caught airborne water of condensation, the blower inlet regain reduced, and had strengthened the negative ability of systems for moisture removal dehumidification effect, played effects such as stable furnace condition, raising gas blower operational efficiency, protection blower vane.
The technical scheme of the utility model: the blast furnace blast systems for moisture removal water of condensation catcher device of the utility model comprises housing and water of condensation catcher; Housing comprises the lattice frame that is made up of outer steel plate and dividing plate; The water of condensation catcher is every water of condensation capture unit at a distance from interior insertion in lattice frame, and the water of condensation capture unit comprises the capture unit framework, and many group capturing elements from top to bottom are installed in the capture unit framework; Every group of capturing element comprises that the slope steel plate of installing in face of wind direction is a first step capturing element; The steel honeycomb filter screen that slope steel plate upper level is placed is a second stage capturing element, and the low side of slope steel plate bends to tank, and the tank side is installed the vertical drainage pipe in the capture unit framework; The water-in that communicates with tank is arranged on the water shoot, and the bottom of water shoot feeds header tank.
Described steel honeycomb filter screen is constrained in the honeycomb filter screen in the screen frame.
Angle β=25～45 of described slope steel plate and horizontal direction °.
The beneficial effect of the utility model: the utility model solved effectively air in the dehumidification process along with temperature reduces, saturated regain reduces; Water vapor can't be caught after forming water of condensation, the removal problem; Strengthened negative ability dehumidification effect; Improve the gas blower operational efficiency simultaneously, and played stable conditions of blast furnace, the effect of raising iron output.

Embodiment
Fig. 1 is the water of condensation catcher master TV structure figure of the utility model: the blast furnace blast systems for moisture removal water of condensation catcher device of the utility model comprises housing 1 and water of condensation catcher; Its housing 1 comprises the lattice frame that is made up of outer steel plate 1.1 and dividing plate 1.2, and the water of condensation catcher comprises every water of condensation capture unit 2 at a distance from interior insertion in the lattice frame.
Like Fig. 2, Fig. 3: water of condensation capture unit 2 comprises capture unit framework 2a; Many group capturing elements from top to bottom are installed in the capture unit framework 2a; Every group of capturing element comprises that the slope steel plate 2b that installs in face of wind direction is a first step capturing element; The steel honeycomb filter screen 2c that slope steel plate 2b upper level is placed is a second stage capturing element, and the low side of slope steel plate 2b bends to tank 2b1, and tank 2b1 side is installed vertical drainage pipe 2d in the capture unit framework 2a; The water-in 2d1 that communicates with tank 2b1 is arranged on the water shoot 2d, and the bottom of water shoot 2d feeds header tank 3.
