Abstract
The utility model discloses a boiler waste gas treating device, wherein a smoke outlet of a boiler is communicated with an exhausting gas flue, a plurality of cooling water tanks surrounding the exhausting gas flue are installed outside the same, a water storage tank is disposed on the upper portion of the cooling water tank which is connected to the water storage tank via a pipeline provided with a circulation pump, and a cooling water inlet, a steam inlet and a water outlet which are respectively provided with a valve are arranged on the water storage tank. The exhausting gas flue is connected to a cyclone dust extractor which is provided with an air inlet at the lower end, an air outlet of the cyclone dust extractor is connected to the flue with an induced draft fan, and the flue is connected to a rinsing groove; a hollow baffle plate is installed in the middle of the rinsing groove, an alkali liquor feed port is arranged at the upper end of the rinsing groove, and a chimney is installed on the upper portion of the rinsing groove; and two or more drencher heads are installed inside the chimney. The boiler waste gas treating device eliminates harmful components of waste gas via a waste gas treating system device, and simultaneously uses vast amount of heat energy brought by the waste gas flowing out of the flue, thereby being capable of not only leading the waste gas discharged from the flue to meet the emission standard to avoid environmental pollution, but also using residue heat of the waste gas to save energy, accordingly the purposes of energy saving and environmental protection are achieved.
Description
Technical field:
The utility model relates to energy-conservation, environment protection equipment field specifically is a kind of device that boiler waste gas is handled that is used for.Be specially adapted to the technological transformation of vertical boiler below 1 ton.
Background technology:
Boiler waste gas is handled perplexing always and is respectively used boiler unit, because of containing a large amount of sulfide, nitrogen oxide and dust in the boiler waste gas, improper as boiler waste gas without any processing or processing method, can cause great pollution to atmosphere and surrounding environment, also waste energy simultaneously.Also there are many units or individual that the boiler waste gas treating apparatus is studied now, though obtained certain achievement, also have some defectives and deficiency, remain further to be improved.
The utility model content:
For solving the waste gas pollution on the environment that boiler produces because of fire coal and how utilizing waste gas when flue is discharged, to contain the problem of a large amount of heat energy, the utility model provides a kind of problem that can solve the boiler waste gas environmental pollution, can utilize the new waste gas treatment system device of waste gas residual heat simultaneously again.
The technical solution adopted in the utility model:
The boiler waste gas treating apparatus: the boiler outlet flue is communicated to exhaust uptake, exhaust uptake is equipped with several cooling water tanks that surround exhaust uptake outward, the cooling water tank top is provided with storage tank, cooling water tank is connected to storage tank by the pipeline of band circulating pump, and storage tank is provided with cooling water inlet, steam inlet, the delivery port of band valve; Exhaust uptake is connected to cyclone dust collectors, there is air inlet the cyclone dust collectors lower end, the air outlet of cyclone dust collectors is connected to the flue of band air-introduced machine, flue is connected to rinsing bowl, hollow baffle plate is installed in the middle of the rinsing bowl, the rinsing bowl upper end is provided with the alkali lye charge door, and the rinsing bowl top is equipped with chimney, is equipped with two in the chimney to a plurality of spray heads.
Its characteristics of the utility model are:
(1) in the boiler waste gas waste heat re-use device, in the flue external welding of boiler outlet flue two sections cooling water tanks, be used for utilizing the heat energy of waste gas when flue is discharged, this heat energy is through heat exchange, make the cold water in the cooling water tank become hot water, hot water can be done boiler water supply after aqua storage tank is collected, also can the consumption that reduces coal for the employee does that bathing and daily life are used; (2) in boiler waste gas water washing device rinsing bowl, be provided with a hollow baffle plate, main effect is to prevent that boiler waste gas time of staying in rinsing bowl is too short, does not reach the effect of washing and dedusting; (3) being equipped with two to a plurality of spray heads in chimney, is that the waste gas through water washing device is washed and dedusting more again.
Advantage of the present utility model:
The utility model is removed oxious component in the middle of the waste gas by the exhaust treatment system device, a large amount of heat energy that the waste gas that utilizes flue to come out simultaneously carries, can make the waste gas of from flue, discharging reach discharge standard and can not cause environmental pollution like this, can utilize waste gas residual heat and energy savings again, thereby realize the target of energy-saving and environmental protection.

The specific embodiment:
Referring to accompanying drawing 1.
The boiler waste gas treating apparatus: boiler 1 outlet flue is communicated to exhaust uptake, exhaust uptake is equipped with several cooling water tanks 2 that surround exhaust uptake outward, the cooling water tank top is provided with storage tank 4, cooling water tank 2 is connected to storage tank 4 by the pipeline of band circulating pump 3, and storage tank 4 is provided with cooling water inlet 10, steam inlet 12, the delivery port 14 of band valve; Exhaust uptake is connected to cyclone dust collectors 5, there is air inlet cyclone dust collectors 5 lower ends, the air outlet of cyclone dust collectors 5 is connected to the flue of band air-introduced machine 6, flue is connected to rinsing bowl 8, hollow baffle plate 11 is installed in the middle of the rinsing bowl 8, rinsing bowl 8 upper ends are provided with alkali lye charge door 9, and the rinsing bowl top is equipped with chimney 7, and several spray heads 13 are installed in the chimney.
In boiler, coal produces the waste gas contain particle and pernicious gas in a large number through combustion reaction, and waste gas carries a large amount of heat energy and since waste gas directly the discharging meeting air is polluted, so we will handle waste gas.The waste gas that comes out from the boiler outlet flue at first passes through the flue that has welded two sections cooling water tanks, in cooling water tank by heat exchange to the waste gas processing of lowering the temperature, utilize the heat energy of waste gas that the water in the water tank is heated simultaneously, can reduce the waste of energy like this, saved the energy, heated water can be done boiler water supply and use, and also can be used as bath water and daily life and uses.This is to handling the first time of waste gas.Boiler waste gas through the cooling of two sections cooling water tanks enters cyclone dust collectors then, can remove most dust in the middle of the waste gas by cyclone dust collectors, and this is to handling the second time of waste gas.The waste gas of removing most of dust enters in the rinsing bowl by air-introduced machine, in rinsing bowl, waste gas is handled for the third time, processing method is: the waste gas that enters in the rinsing bowl fully contacts, reacts with water in the rinsing bowl that is provided with hollow baffle plate, substantially reach the purpose of sulfide, nitrogen oxide and the part dust removed in the waste gas, on rinsing bowl top the alkali lye charge door is housed, the adding one of alkali lye can in and water and sulfide in the rinsing bowl, nitrogen oxide generation chemical reaction and the acid solution that produces, two can make the pH value of water in the rinsing bowl greater than 7.Enter chimney through the waste gas after three processing, because of being equipped with two in the chimney to a plurality of spray heads, water carries out the 4th time through the spray head spray to waste gas to be handled, promptly waste gas is washed and dedusting more again, after boiler waste gas is handled through four times like this, both utilize waste gas residual heat, removed the sulfide in the waste gas, nitrogen oxide and dust again, reached the purpose of energy-conserving and environment-protective.
