Abstract

The utility model belongs to a smoke-removing and cooling machine for a diesel generator set, which comprises a heat exchanger, a spiral smoke pipe, a smoke inlet connecting flange, a water inlet, a water outlet, a smoke guide pipe, a water bath case, a smoke outlet connecting flange, a water-level gauge, a drain valve, a liquid filling nozzle, a temperature controller and a water pump. Exhaust from the generator set enters the spiral smoke pipe in the heat exchanger through the smoke inlet connecting flange and is cooled for three passes efficiently and then washed by smoke-removing liquid sprayed into the water bath case by the smoke guide pipe. After most of black smoke is removed by smoke-removing catalyst, the residual black smoke is washed for removing the smoke further by the smoke-removing liquid, so as to lead the exhaust to be near zero emission. The cooling water in the heat exchanger is cooled circularly by the water pump and an external cooling water tank, and the cooling temperature is controlled automatically by the temperature controller.

Description

Diesel generating set smoke elimination cooling machine

Technical field

The utility model belongs to the device that a kind of diesel generating set tail gas is eliminated black smoke and reduced delivery temperature.

Background technique

The diesel exhaust gas temperature is generally up to good hundreds of degree centigrade, and there is strict requirement in some special place to its delivery temperature, and it is close to reach final delivery temperature and ambient temperature.Thereby under this specific (special) requirements, this device can efficiently reduce its delivery temperature, to reach its specific (special) requirements to delivery temperature.

The diesel engine over-emitting black exhaust is because poor, diesel engine mixed gas generation type of diesel oil volatile performance and combustion manner cause.Reduce the post processing mode that diesel engine carbon black adopts at present both at home and abroad, cause the obstruction exhaust easily, the diesel engine back pressure is increased.This machine be exhaust through the smoke elimination catalyzer is powerful eliminate smoke after, carry out further smoke abatement to remaining a small amount of black smoke, make final exhaust black smoke near zero-emission.

Summary of the invention

The purpose of this utility model provides a kind of diesel generating set smoke elimination cooling device, includes heat exchanger, spiral smoke pipe, advances the cigarette adpting flange, water intake, water outlet, leads smoke pipe, water bath, smoke adpting flange, fluviograph, blowdown valve, spout, temp controller and water pump and form.This device divides two major components, and top is heat exchanger, and the bottom is a water bath.Three groups of smoke pipes of upper, middle and lower are arranged in the overhead heat exchanger, in its pipe spiral wire is housed, so claim the spiral smoke pipe, last group one end with advance the cigarette flange and communicate, the other end communicates with middle group of bending tubes end, middle group smoke end communicates with following group bending tubes end, the smoke pipe of leading of organizing smoke end and heat exchanger down communicates and constitutes three backhaul spiral smoke pipes, the outer cigarette adpting flange of putting into, water intake and water outlet, advance the cigarette flange engine exhaust is introduced inner spiral smoke pipe, all spiral smoke pipes all are immersed in the cooling water, and the exhaust of high temperature is carried out three backhauls and efficiently cooled off in the spiral smoke pipe, and cooling water is by water pump the water intake that the hydraulic pressure in external refrigeration pond advances heat exchanger to be come the cooling spiral smoke pipe, and the cooling water after the heating flows to the cooling pond of outside by the water outlet of heat exchanger, thereby makes cooling water circulation cooling.The bottom water bath is adorned fluviograph, spout, smoke adpting flange outward, and blowdown valve is equipped with in the bottom.Be equipped with under the heat exchanger and lead smoke pipe, its smoke outlet is towards the liquid level that removes tobacco juice of water bath, and near removing tobacco juice, water-bath is carried out in removing in the tobacco juice in the cigarette spirt water bath after the cooling, further reduces black smoke concentration, makes black smoke in the exhaust near zero-emission.Final exhaust is discharged through the smoke adpting flange.The cooling effect of exhaust is to reach through the speed of circulation that temp controller is controlled cooling water automatically.

The utility model compared with prior art has following characteristics owing to adopt as above design:

1, is used with the smoke elimination catalyzer, can makes exhaust near zero-emission;

2, reduce delivery temperature, can reach below 30 ℃.

Embodiment

As shown in drawings: diesel generating set smoke elimination cooling machine by blowdown valve (1), remove tobacco juice (2), water bath (3), fluviograph (4), spout (5), spiral smoke pipe (6), heat exchanger (7), cooling water (8), advance cigarette adpting flange (9), water outlet (10), temp controller (11), water pump (12), smoke adpting flange (13), water intake (14), lead smoke pipe (15) and form.

Water outlet (10) is housed on the overhead heat exchanger of this device (7), advances cigarette adpting flange (9) and water intake (14), interior dress spiral smoke pipe (6) and lead smoke pipe (15), all spiral smoke pipes (6) all are immersed in the cooling water (8); The outer dress of bottom water bath (3) fluviograph (4), spout (5), smoke adpting flange (13) and blowdown valve (1), interior dress removes tobacco juice (2); Water pump (12) is fixed on water bath (3) bottom, and temp controller (11) is positioned at the top of heat exchanger (7).

During use, the exhaust of diesel generating set cools through the spiral smoke pipe (6) that advances cigarette adpting flange (9) and enter in the heat exchanger (7).Exhaust because the spiral wire in the smoke pipe stirs, makes it form wadding stream, and cools off repeatedly through three backhauls, to reach efficient cooling purpose in spiral smoke pipe (6).Cooled exhaust sprays to and removes tobacco juice (2) in the water bath (3) through leading smoke pipe (15), cleans remaining black smoke, and further cooling.Exhaust through above-mentioned smoke elimination cooling is discharged through smoke adpting flange (13).

Cooling water (8) be by water pump (12) with the cooling water in the external cooling pond in water intake (14) is pressed into heat exchanger (7), spiral smoke pipe (6) is cooled off, circulate after water outlet (10) is discharged to external cooling pond.

[0014] temp controller (11) is by the control to water pump (12) flow velocity, to reach the purpose of automatic control coolant exhaust temperature.
