Problems solved by technology

[0003] Generally, the hot flue gas or smoke is high temperature and contains a lot of polluting particles or dust inside. If it is directly discharged through the chimney, it will pollute the environment. The existing chimney will be equipped with a filtering and cooling system, but inside the chimney The specific situation of the exhaust gas or smoke cannot be fixed. Sometimes the amount of smoke is large and the temperature is high, and sometimes the amount of smoke is small and the temperature is low. It cannot be circulated. Secondly, in the prior art, it is impossible to control the wind direction in the chimney according to the different situations of smoke.

Embodiment 1

[0060] see figure 1 As shown, the purpose of this embodiment is to provide a chimney heat dissipation constant temperature air duct air volume control algorithm with dust removal and cooling functions, including the following method steps:

[0061]S1. The main air system of the chimney forms an airflow, and the smoke is driven to flow out through the chimney through the action of the airflow;

[0062] S2. During the process of the smoke flowing out through the chimney, wherein:

[0063] The cooling system in the chimney cools the smoke;

[0064] The dust removal system in the chimney removes dust from the smoke;

[0065] S3. After cooling down and dust removal, the monitoring system will monitor the temperature, air volume and dust content of the smoke in the chimney in real time, and form a feedback command;

[0066] S4. The return air system receives the feedback instruction formed by the monitoring system, and controls the air volume and wind direction in the chimney thr...

Embodiment 2

[0072] Considering that the dust content of the smoke in the chimney is different, and when the smoke volume is large and the temperature is high, it is not enough to only cool down and filter once. For this, please refer to image 3 As shown, the dotted arrow in the figure indicates the air flow direction, and the return air system includes an inner pipe body 200 and a return air flow output device 300, wherein:

[0073] The inner pipe body 200 is arranged outside the main airflow output device 600, and its main purpose is to isolate the airflow formed by the main airflow output device 600 and the return airflow output device 300, so as to avoid the inability to effectively circulate the airflow caused by convection. A return air passage is formed between the outer wall of 200 and the inner wall of the outer pipe body 100, and a plurality of return air outlets 210 are arranged in a circular array on the inner pipe body 200, and the return air flow output device 300 is arranged...

Embodiment 3

[0078] Considering that in the process of later use, it is necessary to monitor the smoke exhaust volume, dust content of the smoke and the temperature of the smoke, so as to ensure the efficient operation of the chimney and avoid problems that cannot be detected in time when the chimney fails, please refer to Figure 4 As shown, the monitoring system includes a temperature sensor 220, a smoke sensor 230 and an air volume sensor 110, wherein:

[0079] The smoke sensor 230 is arranged near the top of the filter layer 500, that is to say, the filtered smoke will be detected by the smoke sensor 230 immediately, so as to prevent the smoke from contacting the air for a long time during the flow process, resulting in an increase in the error of the monitoring results, and , the temperature sensor 220 is set on the top of the smoke sensor 230, since the condensation area of ​​the condensing fin plate 400 has covered the entire chimney, so setting it on the top can more accurately det...

Abstract

The invention relates to the technical field of air volume control, in particular to a chimney type heat dissipation constant-temperature air duct air volume control algorithm with dust removal and cooling functions. The method comprises the steps of forming airflow by a main air system of the chimney; cooling and dedusting; a real-time monitoring step; and a control step. Smoke in the chimney is cooled and dedusted through the cooling system and the dedusting system, so that pollution to air is reduced, the temperature, the air volume and the dust content of the smoke in the chimney are monitored in real time through the monitoring system, then the monitored condition is fed back to the air return system, the air return system is used for control, air return is conducted on the smoke, and the smoke quality is improved. And a cooling system and a dust removal system are matched to carry out circulating cooling and dust removal, so that smoke finally exhausted by the chimney is low in temperature and low in dust, and the environmental protection property of smoke exhaust of the chimney is improved.

Description

technical field [0001] The invention relates to the technical field of air volume control, in particular to an air volume control algorithm of a chimney-type heat dissipation constant temperature air duct with dust removal and cooling functions. Background technique [0002] A chimney is a structure that provides ventilation for the hot flue gases or smoke of a boiler, furnace, furnace or fireplace. Chimneys are usually vertical, or as close to vertical as possible, to ensure a smooth flow of gases, drawing air into what is known as stack combustion or the stack effect. [0003] Generally, the hot flue gas or smoke is high temperature and contains a lot of polluting particles or dust inside. If it is directly discharged through the chimney, it will pollute the environment. The existing chimney will be equipped with a filtering and cooling system, but inside the chimney The specific situation of the exhaust gas or smoke cannot be fixed. Sometimes the amount of smoke is large...
