Description

A Boiler Waste Heat Dust Collector

technical field

The invention relates to a dust collector, in particular to a boiler waste heat dust collector.

Background technique

Energy saving and emission reduction has become an important task of various industrial sectors. At present, most of the existing boilers do not have dust removal facilities. The smoke and dust released during combustion are directly discharged into the atmosphere. The smoke and dust carry a large amount of heat. Pollution has brought serious harm to human beings, and the heat carried in the smoke has not been fully utilized, wasting energy. Although some boilers are additionally equipped with dust removal, the structure is complicated and the cost is high and cannot be popularized.

Contents of the invention

The object of the present invention is to provide a boiler waste heat dust removal purifier which has simple structure, low cost, good dust removal effect and can make full use of the heat carried in the smoke.

Technical scheme of the present invention is realized like this:

A boiler waste heat dedusting purifier, including a purified water tank, a chimney inlet, a waste heat box, a waste heat dust collector and a dust removal chamber, the chimney inlet is connected to the waste heat dust collector in the waste heat box, and a hot air outlet is provided at the lower part of the waste heat box, and the hot air outlet passes through the hot air The pipe is connected to the furnace of the boiler, and the upper part of the waste heat box is provided with a suction port. The waste heat dust collector is equipped with a dust removal chamber and a dust collector smoke pipe. In the purified water tank, the top of the purified water tank is provided with a water supply port, and the bottom of the purified water tank is provided with an outlet of the purified water tank. After being purified by the purified water tank, the smoke and dust of the boiler is discharged through the smoke outlet of the purified water tank provided on the upper part.

The dedusting pipe is connected in a detour in the dedusting chamber, which increases the stroke of the dedusting pipe, enables the heat carried in the dust to be fully collected by the waste heat box and enhances the dedusting effect.

The boiler waste heat dedusting purifier of the present invention adopts primary dedusting and secondary water purification, which not only reduces the discharge of smoke and dust, but also reduces the pollution of harmful smoke to the atmosphere. The lower part of the waste heat dust collector is equipped with a hot air outlet, which is connected to the boiler furnace through a hot air pipe to make full use of the waste heat of the smoke and dust, and a water purification device is installed to reduce the pollution of carbon dioxide and sulfur dioxide to the atmosphere.

detailed description

In order to introduce the present invention in more detail, the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, the boiler waste heat dust removal purifier includes a purified water tank 31, a chimney inlet 35, a waste heat tank 36, a waste heat dust collector 37 and a dust removal chamber 38, and is characterized in that: the chimney inlet 35 is connected to the waste heat dust collector in the waste heat box 36 Heater 37 and the lower part of waste heat box 36 are provided with a hot air outlet 34, which is connected to the boiler furnace 30 through a hot air pipe 33; The smoke pipe 39 of the dust collector and the dust collection box 42 are arranged under the dust removal chamber 38. The smoke pipe 39 of the dust collector is connected to the purified water tank 31 through the smoke outlet pipe 41 of the dust collector. Outlet 45, the smoke and dust of the boiler is discharged through the smoke outlet 44 of the purified water tank provided on its top after being purified by the purified water tank 31.

The working principle of the present invention: the smoke and dust of the boiler enter the waste heat dust collector 37 from the chimney inlet 35, and the waste heat carried by the smoke and dust is collected by the waste heat box 36, and then discharged to the boiler furnace 30 through the hot air outlet 34 through the hot air pipe 33, and the smoke and dust pass through the dust removal After the chamber 38 and the smoke pipe 39 of the dust collector settle down, they pass through the smoke outlet pipe 41 of the dust collector to the purified water tank 31. After the dust is purified by the water in the purified water tank 31, it is discharged from the smoke outlet 44 of the purified water tank provided on its upper part, and the dust removal and purification of the smoke is completed; When the purified water in purified water tank 31 li was not enough, the replenishment port 32 provided with its top provided purified water, and when the purified water in purified water tank 31 li was turbid, it was discharged by the purified water tank outlet 45 provided at its bottom.
