Nozzle capable of intelligently improving suction force in ascending pipe

Abstract

The invention provides a nozzle capable of intelligently improving suction force in an ascending pipe. The nozzle is connected to one end of a bridge pipe through threads, the outlet pressure P2 of the nozzle is obtained through a specific formula by measuring the inlet pressure P1 of ammonia water entering the bridge pipe and the throat diameter d2 of the nozzle, and according to the requirementfor the pressure value needed by customers, based on the condition that the unit volume flow, the fluid medium density and the inlet diameter are not changed, the requirements of customers for the pressure value of the outlet end of the nozzle are met by measuring and adjusting the technological parameters of the inlet pressure value and the throat diameter of the nozzle. Meanwhile, the inventionfurther provides a specific structure of the nozzle. The nozzle can enable a gas collecting pipe to fully suck raw gas by utilizing negative pressure when coal is charged into a carbonization chamberafter the negative pressure in the ascending pipe reaches the negative pressure required by the process, so that the dissipation of the raw gas is reduced, and the effects of dust reduction and dust removal are achieved.

Description

technical field [0001] The invention belongs to the technical field of nozzles for rising pipes of coke ovens, and relates to a nozzle for intelligently improving the internal suction of rising pipes. Background technique [0002] In the coke oven production process, the ammonia water nozzle is an important component of the coke oven riser, which is installed at the turning of the bridge tube, and its function is to inject hot ammonia water and cool the crude gas by means of ammonia water evaporation. There is also a steam nozzle on the bridge pipe. When coal is loaded into the carbonization chamber, the negative pressure generated by steam or ammonia water injection guides the crude gas into the gas collection pipe to reduce the smoke escaping from the coal charging hole, so as to achieve dust reduction and dust removal. , to improve the site environment. [0003] But now there are installed ammonia water nozzles, the bridge pipe for spraying high-pressure ammonia water ca...
