Description

Bubble spray desulfurization dust collector

The utility model relates to a dust remover, in particular to a bubbling spray desulfurization dust remover.

Background technique

Common wet desulfurization and dust removal purification equipment include spray type, cyclone type, water storage impact water bath type, tray type, Venturi type, etc. However, usually due to the sulfur in the flue gas, the dust removal equipment is easy to corrode after contacting with water. Secondly, due to the limitation of various factors, the dust removal efficiency of a single dust collector is not very high.

Contents of the invention

The purpose of this utility model is to provide a bubbling spray desulfurization and dedusting device, which is made of granite and has the effect of anti-corrosion. The purification and dust removal efficiency of sulfur-fired coal flue gas, the appearance and structure of the equipment are simple, which reduces the cost of equipment manufacturing, reduces energy consumption during use, and is low-carbon and environmentally friendly.

The utility model is achieved in this way, it includes the entrance smoke chamber, reaction area, spray pipe, upper partition, lower partition, limestone slurry pool, air outlet, the entrance smoke chamber is connected with the reaction area to form an air inlet channel, its characteristic The bottom of the entrance smoke chamber is connected with a spray pipe, and the upper end of the reaction zone is staggered up and down to connect the upper partition and the lower partition to form a bubbling zone. The lower end of the reaction zone is provided with a limestone slurry pool, and the bubbling zone The lower partition in the middle is directly inserted below the liquid level of the ash settling tank, and the side wall of the reaction zone is provided with an air outlet.

The flue gas enters the entrance smoke chamber, and the bottom of the entrance smoke chamber is connected with a spray pipe. After the gas enters the dust collector, it is sprayed immediately, and the dust is wetted by the atomized liquid droplets, and the dust particles and water droplets or dust particles and dust particles condense It is easier to be trapped and achieve the first purification after full contact. The subsequent structure is a bubbling area composed of upper and lower partitions. A limestone slurry pool is arranged at the lower end of the bubbling area. The lower partition in the bubbling area is directly inserted below the liquid level of the ash settling tank, so that The gas hits the water surface continuously again to achieve the second purification. Bubbles in the bubbling area are continuously and rapidly generated and broken to further strengthen the gas-liquid contact, and new contact surfaces are constantly generated, and at the same time, the reactants are transferred from the bubbling area to the reaction area. There are a large number of air bubbles in the reaction area, and the fresh The absorbent comes into contact with the flue gas. The dust particles in the airflow are captured by the water film of the limestone slurry tank, and the purified gas is discharged from the gas outlet to achieve high-efficiency purification.

The technical effects of the utility model are: improving the purification efficiency of coal-fired flue gas, effectively achieving the purpose of desulfurization and dust removal, simple appearance, low production cost, energy saving, environmental protection, and low carbon.

Detailed ways

As shown in Figure 1, the utility model is realized in this way, which includes an inlet smoke chamber 1, a reaction zone 2, a spray pipe 3, an upper partition 4, a lower partition 5, a limestone slurry pool 6, and an air outlet 7. The entrance smoke chamber 1 is connected to the reaction zone 2 to form an air intake channel, and the bottom end of the entrance smoke chamber 1 is connected with a spray pipe 3, and the upper end of the reaction zone 2 is sequentially staggered up and down to connect the upper partition 4 and the lower partition 5 to form bubbling The lower end of the reaction zone 2 is provided with a limestone slurry tank 6, the lower partition 5 in the bubbling zone is directly inserted below the liquid level of the ash settling tank 6, and the side wall of the reaction zone 2 is provided with an air outlet 7. When the flue gas enters the entrance smoke chamber, the bottom of the entrance smoke chamber is connected with a spray pipe, and the gas is sprayed immediately after entering the dust collector, and the dust is wetted by the atomized liquid droplets, and dust particles and water droplets or dust particles and dust particles Coagulation is easier to be trapped, and the first purification is achieved after sufficient contact. The subsequent structure is a bubbling area composed of upper and lower partitions. A limestone slurry pool is arranged at the lower end of the bubbling area. The lower partition in the bubbling area is directly inserted below the liquid level of the ash settling tank, so that The gas hits the water surface continuously again to achieve the second purification. Bubbles in the bubbling area are continuously and rapidly generated and broken to further strengthen the gas-liquid contact, and new contact surfaces are constantly generated, and at the same time, the reactants are transferred from the bubbling area to the reaction area. There are a large number of air bubbles in the reaction area, and the fresh The absorbent comes into contact with the flue gas. The dust particles in the airflow are captured by the water film of the limestone slurry tank, and the purified gas is discharged from the gas outlet to achieve high-efficiency purification.
