Description

Cyclone wet bag filter

technical field

The utility model relates to coal-fired boiler flue gas desulfurization and dust removal equipment, in particular to a cyclone wet bag filter.

Background technique

Common flue gas desulfurization and dust removal devices for coal-fired boilers include spray type, water film type, Venturi tube type, impact purification type, etc. In order to improve the dust removal efficiency, people usually use them in series, which increases their footprint , the production cost is greatly increased.

Contents of the invention

The purpose of the utility model is to provide a cyclone wet bag filter with simple structure, good dust removal effect and low production and use costs.

The cyclone wet bag dust collector of the utility model includes a shell, an air inlet, an air outlet and a nozzle, and is characterized in that the inside of the shell is divided into a spray partition room, a bag room, a water-sealed ash bucket and a liquid collection pool, The spray partition room and the cloth bag room are located in the upper part of the shell, and the water-sealed ash bucket and the liquid collection tank are located in the lower part of the shell; the air inlet is opened on the spray partition room, and the spray partition room is equipped with staggered The spray head is installed on the top of the spray partition room, and the bottom of the spray partition room communicates with the water-sealed ash hopper, which has a sewage outlet; the bag room is equipped with a cloth bag, which is connected to the vibrator, and through vibration Vibration of the filter shakes off the dust on the bag, the air outlet is opened on the bag room, a demisting sieve is set between the bottom of the bag room and the water-sealed ash hopper, and the bag room passes through the demisting sieve and the water-sealed ash hopper, The spray partition room is connected; the water-sealed ash hopper and the liquid collection tank are separated by an overflow plate, and an overflow hole is opened above the overflow plate, and the water-sealed ash hopper and the liquid collection tank are connected by an overflow hole; the liquid collection A water pump is installed on the pool, and the water pump is connected with the nozzle on the spray partition chamber through the circulation pipe, so that the purification liquid can be recycled.

The cyclone wet bag dust collector of the utility model, when working, the flue gas first enters the spray partition room from the air inlet to spray and wash, and impacts the water-sealed ash bucket for water bath dust removal, and then eliminates dust in the bag room on the top of the shell. Fine particles, the flue gas is further dedusted and discharged from the gas outlet.

The cyclone wet bag dust collector of the utility model integrates multiple dust removal methods, has the characteristics of simple structure, low production cost, and high purification efficiency of coal-fired flue gas. The unique design enables the recycling of the purification liquid to achieve the effect of energy saving and emission reduction.
