Problems solved by technology

The dust removal effect of this method is better, but there are still some defects as follows: (1) The effect of this method is acceptable for top-loading coke ovens, but the defects are obvious for coke ovens
Although this method has better dedusting effect and less investment, it also has many disadvantages, mainly: (1) the precious raw gas is not recycled; The gas is incinerated, (3) the sealing problem of the coal-loading flue gas entering the water-sealed main pipe has not been completely solved, (4) the solution for the smoke at the furnace end on the machine side has not been proposed

Abstract

The invention discloses a leakage-free coaling and coke pushing combined smoke purifying and recycling system and a technology for a coke oven, which comprises the coke oven (1), a coke pushing device (2) and a coke guide (3), wherein a double-U-shaped water sealing smoke guide car (6) and a high-pressure ammonia water system (7) are connected with a furnace top gas collecting tube (4) through which the coke oven is led to a chemical product recycling and purifying system (5); a smoke collecting hood (8) is equipped on an oven side furnace end of the coke oven; the smoke collecting hood is connected with a U-shaped water sealing dust-removal dry tube (10) through a leakage-free seal connecting device (9) equipped on the double-U-shaped water sealing smoke guide car; an automatic ignition burning device (11), a Venturi dust-removal device (12), a desulfurization system (13) and a fan (14) are connected in sequence behind the U-shaped water sealing dust-removal dry tube; and a discharge pipe of the fan is led to a quenching tower. The leakage-free coaling and coke pushing combined smoke purifying and recycling system and the technology for the coke oven are low in power consumption, low in investment and good in dust removal effect, and fit for all coke ovens.

Description

technical field [0001] The invention relates to the technical field of dust purification, recovery and treatment for coke oven coal charging and coke pushing in the coking industry. Background technique [0002] During the coal charging process of the coke oven, due to the rise of the hot air in the furnace, raw coal gas, water vapor and a large amount of dust generated by the pyrolysis of the coal material emerge from the coal charging hole; at the same time, during the coke pushing process of the coke oven, with the Moving and collapsing, there will also be a large amount of coke dust escaping inside the coke grid and at the outlet of the coke grid, causing surrounding environment and air pollution and waste of energy. At present, the common methods of coal charging, coke removal and dedusting mainly include: (1) Furnace top smoke elimination and dust removal vehicle and coke pushing ground dust removal station method, this method furnace top smoke elimination vehicle not ...
