Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in FIG. 1, the detection device for the boiler exhaust gas comprises a cooler 1, a dust remover 2 and a detector 3 which are sequentially arranged along the advancing direction of the exhaust gas, wherein the cooler 1 is communicated with the dust remover 2 through a first air pipe 4, and the dust remover 2 is communicated with the detector 3 through a second air pipe 5. During detection, the boiler waste gas firstly enters the cooler 1 for cooling, then enters the dust remover 2 for dust removal, and then the carbon and sulfur content of the boiler waste gas is detected through the detector 3. The cooling is carried out through the cooler 1, the situation that the detection module of the detector 3 is damaged due to overhigh temperature of the waste gas is avoided, the dust is removed from the boiler waste gas through the dust remover 2, the interference of the dust to the detection of the boiler waste gas is eliminated, and the accuracy of the detection result is ensured.

A cooling chamber 6 is provided in the cooler 1, a heat exchanger 7 for cooling the exhaust gas is provided in the cooling chamber 6, and two heat exchangers 7 are provided, one at each of two opposite side walls of the cooling chamber 6. The surface of the heat exchanger 7 is provided with radiating fins, the interior of the heat exchanger is provided with a cooling pipeline 8, when the heat exchanger is used, the radiating fins absorb the heat of the boiler waste gas, cold water is introduced into the cooling pipeline 8, and the cold water takes away the heat on the radiating fins when circulating, so that the purpose of cooling the boiler waste gas is achieved. In order to provide better cooling effect for the cooling pipeline 8, the cooling pipeline 8 is distributed in the heat exchanger 7 in an S shape, so that the path of cold water passing through the heat exchanger is prolonged, the residence time of the cold water is prolonged, the cold water is more fully contacted with the radiating fins, and the cooling effect is ensured.

Because contain a large amount of steam in the boiler waste gas, when in through cooler 1, steam meets cold can liquefy into the water droplet and attaches on the inner wall of cooling chamber 6, along with the continuous work of cooling chamber 6, the water droplet also can accumulate more and more, causes humidity too big in the cooling chamber 6 to influence the water content in the boiler waste gas, disturb the detection of follow-up boiler waste gas. In order to solve the problem, a water absorption silica gel layer 9 is arranged at the bottom of the cooling chamber 6 and is used for absorbing water vapor which is liquefied when meeting cold in the boiler waste gas, and the humidity in the cooling chamber 6 is ensured to be in a normal range.

A temperature control valve 10 is arranged at one end of the first air pipe in the cooling chamber 6 and used for controlling the temperature of the air passing through the first air pipe. When the induction part of the temperature control valve detects that the gas in the cooling chamber 6 is overheated, the temperature control valve is automatically closed, the boiler waste gas is prevented from entering the subsequent detector 3, and the detection module in the detector 3 is protected from being damaged by the heat brought by the boiler waste gas, so that the detection precision is ensured.

Further, when the gas in the cooling chamber 6 is overheated, the thermostatic valve is closed, which may cause the air pressure in the cooling chamber 6 to be too high, so that there is a certain potential safety hazard, and in order to eliminate the potential safety hazard, a pressure release valve 11 is arranged at the top of the cooling chamber 6, and when the air pressure in the cooling chamber 6 is too high, the pressure release valve 11 is automatically opened to release the pressure in the cooling chamber 6, so as to ensure that the pressure value in the cooling chamber 6 is in a safe range.

A filter screen 12 is arranged in the dust remover 2, a dust collecting chamber 13 is arranged at the bottom of the dust remover 2, an air inlet of the dust remover 2 is positioned between the filter screen 12 and the dust collecting chamber 13, and an air outlet is positioned above the filter screen 12. When the dust collector is used, the dust in the boiler waste gas is filtered by the filter screen 12, meanwhile, the dust falls into the dust collecting chamber 13 under the action of gravity, and the dust collecting chamber 13 is cleaned regularly to remove the dust.

Further, a micro vibration motor 14 is provided on the lower surface of the filter screen 12. When filter screen 12 filters, although most dust can drop under its action of gravity in the dust collection room 13, but also few parts can be attached to the lower surface of filter screen 12, long-term accumulation can influence the air permeability of filter screen 12, drives filter screen 12 vibrations through miniature shock dynamo 14, can shake the dust on filter screen 12 surface and fall to guarantee the air permeability of filter screen 12.
