Description

The invention relates to mechanical engineering, and specifically to exhaust gas cleaning systems for internal combustion engines.

The purpose of the invention is to reduce the size and intensity of the combined neutralizer.

FIG. 1 shows a neutralizer, a general view; in fig. 2 is a view A of FIG. one.

The combined exhaust gas converter of an internal combustion engine contains a series-connected catalytic cleaning unit 1 and a liquid cleaning unit 2. The catalytic purification unit 1 is provided with inlet 3 and outlet 4 apertures. The liquid cleaning unit includes a filter element 5 and a tank 6 connected to each other, equipped with an inlet 7 and an outlet 8 and partially filled with neutralizing fluid 9, a feed receiver 10 and a non-melting chamber 11. The catalytic unit 1 is placed above the tank 6 with a neutralizing fluid , and consumable receiver 10 - above the float chamber I.

The catalytic unit 1 and the unit 2 liquid cleaning are placed in a common housing. Between the float chamber 11 and the tank 6, a connecting chamber 12 is made, divided by wall 13 into two vertical floats 14 and 15, the first 14 of which are connected to the outlet 4 of the catalytic unit by the upper part and the float chamber 11 through the window 16. the cavity 15 is in communication with the upper part with the tank 6 above the level of the neutralizing liquid 9, and the lower part through the holes 17 with the first cavity 14.

The filter element 5 is made in the shell 18, placed in the walls of the connecting chamber 12 and communicated on one side with the tank 6, and on the other hand with the float chamber 11.

In the tank 6 above the level of the neutralizing fluid 9 are placed the drop-breaking plates 19.

The combined neutralizer works as follows.

Before starting operation, the receiver 10 and the float chamber 11 are filled with a neutralizing liquid through the filler neck, the liquid also fills the tank 6 of neutralizing liquid through the window 16, the holes 17 and the filtering element 5, which is a connecting chamber.

The exhaust gases through the inlet 3 and the perforations enter the catalytic purification unit 1, which is cleaned of carbon monoxide, hydrocarbons and partially soot, and then enter the vertical cavity 14, where, mixing with the neutralizing liquid, partially transforms into steam, through holes 17 into cavity 15, are forced out

liquid and enter the tank 6 with a neutralizing liquid 9, carrying out the contact of soot with vapors and solution droplets. Here there is a sharp decrease in the gas flow rate and the accumulation of an excess amount of non-evaporating solution, as well as the delay of soot, hydrocarbons and other toxic components.

As the level of the neutralizing liquid in the tank 6 rises above the level in the float chamber 11, it flows to the latter through the filter element 5. Thus, after cleaning, the liquid enters the float chamber 11 for reuse.

Next, the gases pass through a system of drop-breaking nlastins 19, where they condense. The purified gases enter the atmosphere through the outlet 8.

The connection of the float chamber with the receiver of the spent liquid through a connecting chamber with a filter element and the use of a droplet-free plastic system allows the neutralizer life to be extended without additional filling to neutralize it by cleaning and reusing it without increasing the neutralizer volume, which reduces vehicle downtime , and the connection of the tank with the neutralizing liquid of the float chamber and the receiver of the spent liquid in one m case allows to reduce the gab Rita converter that enables saving of metal.

The invention relates to mechanical engineering, and specifically to exhaust gas cleaning systems for internal combustion engines. The purpose of the invention is to reduce the size and intensity of the combined neutralizer. FIG. 1 shows a neutralizer, a general view; in fig. 2 is a view A of FIG. 1. The combined exhaust gas converter of an internal combustion engine contains a series-connected catalytic cleaning unit 1 and a liquid cleaning unit 2. The catalytic purification unit 1 is provided with inlet 3 and outlet 4 apertures. The liquid cleaning unit includes a filter element 5 and a tank 6 connected to each other, provided with an inlet 7 and an outlet 8 and partially filled with neutralizing liquid 9, a feed receiver 10 and a non-melting chamber 11. The catalytic unit 1 is placed above the tank 6 with a neutralizing liquid, and consumable receiver 10 - above the float chamber I. The catalytic unit 1 and the liquid purification unit 2 are located in a common housing. Between the float chamber 11 and the tank 6, a connecting chamber 12 is made, divided by wall 13 into two vertical floats 14 and 15, the first 14 of which are connected to the outlet 4 of the catalytic unit by the upper part and the float chamber 11 through the window 16. the cavity 15 is communicated with the upper part with the tank 6 above the level of the neutralizing liquid 9, and the lower part through the holes 17 with the first cavity 14. The filter element 5 is made in the shell 18 placed in the walls of the connecting chamber 12 and communicated from one side with b com 6, and on the other side - with the float chamber 11. The tank 6 above the level of liquid 9 has neutralizing eliminator plate 19. The combined catalytic converter operates in the following-manner. Before the start of operation, the receiver 10 and the float chamber 11 are filled with a neutralizing liquid through the filler neck, the liquid also fills the tank 6 of neutralizing liquid through the window 16, the holes 17 and the filtering element 5, which is a connecting chamber. The exhaust gases through the inlet 3 and the perforations enter the catalytic purification unit 1, which is cleaned from carbon monoxide, hydrocarbons and partially from soot, and then enter the vertical cavity 14, where, mixing with the neutralizing liquid, partially transforms into the vapor flows through the openings 17 into the cavity 15, displaces the liquid and enters the tank 6 with the neutralizing liquid 9, making contact with the soot with the vapors and droplets of the solution. Here there is a sharp decrease in the gas flow rate and the accumulation of an excess amount of non-evaporating solution, as well as the delay of soot, hydrocarbons and other toxic components. As the level of the neutralizing liquid in the tank 6 rises above the level in the float chamber 11, it flows to the latter through the filter element 5. Thus, after cleaning, the liquid enters the float chamber 11 for reuse. Next, the gases pass through a system of drop-breaking nlastin 19, where their condensation occurs. The cleaned gases enter the atmosphere through the outlet 8. The connection of the float chamber with the receiver of the spent liquid through the connecting chamber with the filter element and the use of a drop-breaking plastip system allow the neutralizer to prolong the life of the neutralizer without additional pouring and neutralize it with liquid volume of the neutralizer, which reduces vehicle downtime, and the connection of the tank with the neutralizing liquid of the float chamber and the receiver and the used liquid in one m case allows to reduce the dimensions of the neutralizer, which saves metal.
