Description

one

This invention relates to a technique for cleaning dust from gases and can be used in industries that need to clean gases before being released into the atmosphere.

The aim of the invention is to intensify the process of dust collection and the distribution of the sustainable operating range of the device.

Figure 1 shows the proposed device, a General view; Fig.2 contact device, cross section; on fig.Z - the same, longitudinal section

The device includes a coagulative chamber 1, coaxially mounted accelerating tubes 2 at the ends of which ring nozzles 3 are located, which in the upper part are interconnected by a reflector 4, which serves to direct the gas flows downwards. The liquid is supplied to the annular nozzles 3 through the nozzles 5. The coagulation chamber 1 is equipped with a nozzle 6 for the exit of the purified gas and a nozzle 7 for draining the pulp. Pa3i-OHinjie tubes are filled with holes 8 around the circumference.

The device works as follows.

Dust gas streams are directed towards the acceleration tubes 2 towards each other. In the annular nozzles 3, through the nozzles 5, a liquid is supplied, which through the channels formed between the annular nozzles 3 and the accelerating pipes 2, i-; the form of longitudinal jets into the space between the ends of the accelerating pipes 2, due to the higher density and inertia compressing the cylindrical curtain, and the form of transverse jets through the holes 8, made around the output ends of the accelerating pipes 2 into their internal cavity, blocking the cross section. Liquid sprayed through the entire volume of gas, jets of it, moving at the surface of the pipe at high speed, prevent the formation of deposits.

In f) sulphate gas flows to the outlet. 1- de from the accelerating pipes 2 are intensively irrigated with liquid and the phase flows are moving towards each other inside the crimping cylindrical curtain. Stable compression by liquid streams of gas streams about {n psci 1: 3
