Description

Smoke fog drop sampling bottle

Technical Field

The utility model relates to a flue gas sampling bottle, concretely relates to diammonium phosphate device sprays washing tail gas droplet sampling bottle.

Background

The production of diammonium phosphate can generate a large amount of dust and NH in the granulation, drying, cooling and conveying sections₃Tail gas, dust and NH in the tail gas are treated by a cyclone dust collector and a multistage wet spraying and washing process in the conventional diammonium phosphate device₃. Containing dust and NH₃First stage of tail gasEntering a cyclone dust collector, removing a large amount of dust in the tail gas by using the centrifugal force, and then absorbing NH in the tail gas by multi-stage wet spraying and washing₃And dust, and finally discharged into the atmosphere through a chimney. The wet spraying nozzle atomizes to generate a large amount of fine fog drops with different particle sizes, the fine fog drops are easily carried by tail gas and enter the atmosphere, and the fog drops not only contain water but also dissolve a large amount of soluble salts, such as: ammonium phosphate salts, calcium magnesium phosphate salts, sulfates, fluorides, and the like. The salt compounds can form fine particle pollutants after entering the atmosphere, and cause pollution to the atmosphere.

A liquid drop catcher is proposed in the method for testing the performance of coal-fired flue gas desulfurization equipment (GB/T21508-2008). The trap can only collect fog drops with a particle size larger than a certain particle size, and can not collect fog drops with a small particle size and detect all fog drops in smoke. Meanwhile, the caliber of the sampling nozzle is fixed and can not be replaced, constant-speed sampling can be realized only by adjusting sampling flow, and reasonable sampling flow is not easy to select.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a flue gas droplet sampling bottle to above-mentioned defect.

A smoke fog drop sampling bottle comprises a fog drop collecting bottle, a snakelike glass tube, a glass funnel, a sand core filter plate, a sampling nozzle, a plastic elbow and a rubber plug.

The sampling device comprises a fog drop collecting bottle, a sampling nozzle, a sand core filter plate, a sampling outlet pipe, a rubber plug and a sampling gun, wherein the upper part of the fog drop collecting bottle is connected with an air inlet pipe, the sampling nozzle is connected with the air inlet pipe through a plastic elbow, the sampling nozzle can rotate to adjust the direction, a snake-shaped glass pipe is positioned in the fog drop collecting bottle, one end of the snake-shaped glass pipe is connected with the air inlet pipe, the bottom of the snake-shaped glass pipe is connected with the glass funnel, the funnel opening is provided with the.

The utility model discloses a theory of operation: the flue gas that contains the droplet, with certain speed, get into the droplet sampling bottle through the sampling mouth, the sampling mouth passes through the plastics elbow and links to each other with the intake pipe, but the free rotation regulation of sampling mouth, adapt to the sampling of different flue gas flow directions, after the flue gas that smugglies secretly, the droplet of large particle diameter forms the liquid pearl on attaching to the inner wall of snakelike glass pipe under the effect of gravity and centrifugal force, the liquid pearl flows to the droplet collecting bottle along the glass pipe, and form one deck liquid film on the psammitolite filter plate, the droplet of small particle diameter gets into the funnel along with the flue gas after, the flue gas velocity of flow reduces, simultaneously after passing through the psammitolite filter plate, all catches by the psammitolite filter plate, thereby realize the collection of full particle diameter droplet in. And the fog drops in the flue gas are captured and then discharged from the gas outlet pipe.

The utility model discloses simple structure, easy preparation, convenient to use can accurately gather the droplet of full particle size in the flue gas, and the accurate droplet concentration that detects out in the tail gas for the lectotype of defroster, provides the design foundation, reduces the droplet in the flue gas through increasing the defroster, can effectively reduce flue gas dust concentration. Simultaneously the utility model provides a current fog drip sampling bottle can't gather full particle diameter fog drip, the not removable and the sampling liquid of sampling mouth aperture reveal easily technical problem.
