Description

Technical Field

[0001] The invention relates to the technical field of industrial waste gas collection and treatment, and in particular to an automatic collection, transportation and treatment system for volatile organic waste gas. Background Art

[0002] The volatile organic gas treatment process is relatively mature, but the development of the collection, transportation and automatic control of volatile organic gases is relatively lagging behind.

[0003] The conventional exhaust gas collection system has no air guide plate on the air collecting cover, which fails to concentrate the air volume of the induced draft fan, resulting in wind speed loss, which is likely to cause the wind speed to fail to meet the standard. This solution adds an air guide plate to concentrate the air volume of the induced draft fan on the edge of the air collecting cover to increase the exhaust wind speed and improve the exhaust gas collection efficiency.

[0004] Conventional exhaust gas collection systems have no wind speed monitoring system and automatic control system, and cannot automatically adjust the frequency of the induced draft fan.

[0005] Conventional exhaust gas collection systems have no temperature control system or automatic control system and cannot automatically control the opening and closing of pipelines. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a volatile organic waste gas automatic collection, transportation and treatment system which effectively solves the problem that the frequency of the induced draft fan cannot be automatically adjusted and the opening and closing of the pipeline cannot be automatically controlled in the prior art.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A system for automatically collecting, conveying and treating volatile organic waste gas comprises a plurality of gas collecting covers for collecting waste gas, and the gas collecting covers are connected to each other through waste gas transmission pipes. The waste gas collected by the gas collecting covers is transmitted to waste gas treatment equipment through the waste gas transmission pipes. The waste gas treatment equipment comprises an activated carbon absorption box, an ultraviolet light box and an induced draft fan, and the activated carbon absorption box, the ultraviolet light box and the induced draft fan are sequentially arranged on a control cabinet through pipelines. An automatic speed monitor and an automatic temperature meter are respectively arranged inside the air inlet end of the gas collecting cover.

[0008] Preferably, a cross brace is welded and fixedly provided at the bottom of the gas collecting cover, and the automatic speed monitor and automatic temperature measuring instrument are provided on the cross brace.

[0009] Preferably, the gas collecting cover is a conical structure that is narrow at the top and wide at the bottom, and a guide and a duct butterfly valve electrical switch are respectively provided at the connection between the gas collecting cover and the exhaust gas transmission pipe.

[0010] Preferably, an air guide plate is provided at the middle position of the air inlet end at the bottom of the air collecting cover, and both ends of the air guide plate are welded to the cross brace so that the exhaust gas enters from the edge of the air collecting cover, thereby increasing the air inlet velocity.

[0011] Preferably, the automatic speed monitor is connected to the induced draft fan through a control cabinet, and the automatic thermometer is wirelessly connected to the duct butterfly valve electrical switch through the control cabinet. When the air collection wind speed decreases, the control cabinet automatically converts the frequency of the induced draft fan to ensure its speed. When the automatic thermometer detects that the temperature inside the air collection cover rises, the control cabinet controls the duct butterfly valve electrical switch on the exhaust gas transmission pipe to automatically control the exhaust gas discharge volume.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The wind guide plate is helpful to increase the wind speed around the air collecting cover, increase the air inlet speed, and improve the exhaust gas collection efficiency.

[0013] 2. The automatic temperature measuring instrument is connected to the electrical switch of the butterfly valve on the exhaust gas transmission pipe at the upper end of the gas collecting cover, which can open the pipeline when the equipment heats up and produces exhaust gas, thereby realizing automation and reducing the unsafe factors caused by personnel climbing up to manually open and close the electrical switch of the butterfly valve on the exhaust gas transmission pipe.

[0014] 3. The automatic speed monitor is connected to the control cabinet, which can monitor and adjust the exhaust gas collection wind speed in the gas collecting cover in real time to achieve automation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] like Figure 1-3As shown, a system for automatically collecting, conveying and treating volatile organic waste gas includes a plurality of gas collecting covers 1 for collecting waste gas 8, and the gas collecting covers 1 are connected to each other through waste gas transmission pipes 2, and the waste gas 8 collected by the gas collecting covers 1 is transported to the waste gas treatment equipment through the waste gas transmission pipes 2, and the waste gas treatment equipment includes an activated carbon absorption box 3, an ultraviolet light box 10 and an induced draft fan 11, and the activated carbon absorption box 3, the ultraviolet light box 10 and the induced draft fan 11 are sequentially arranged on a control cabinet 12 through pipelines, and an automatic speed monitor 7 and an automatic temperature meter 6 are respectively arranged inside the air inlet end of the gas collecting cover 1.

[0017] The automatic speed monitor 7 is connected to the induced draft fan 11 through the control cabinet 12, and the automatic thermometer 6 is wirelessly connected to the duct butterfly valve electrical switch 4 through the control cabinet 12. When the air collection wind speed decreases, the control cabinet 12 automatically converts the frequency of the induced draft fan 11 to ensure its speed. When the automatic thermometer 6 detects that the temperature inside the air collection cover 1 rises, the control cabinet 12 controls the duct butterfly valve electrical switch 4 on the exhaust gas transmission pipe 2 to automatically control the discharge amount of the exhaust gas 8.

[0018] When the present invention is in use, the induced draft fan 11 is controlled to work, and the waste gas 8 enters the waste gas transmission pipe 2 through the gas collecting cover 1. Since the induced draft fan 11 is arranged at the rear ends of the activated carbon absorption box 3 and the ultraviolet light box 10 and connected through a pipeline, the waste gas 8 enters the activated carbon absorption box 3 through the waste gas transmission pipe 2, and the large particles in the waste gas 8 are adsorbed by the activated carbon, and then enters the ultraviolet light box 10 to photolyze the waste gas 8 by ultraviolet light. The waste gas 8 is irradiated with ultraviolet light beams to crack the molecular chains of organic or inorganic high molecular weight evil compounds in the industrial waste gas 8, degrade them and transform them into low molecular weight compounds, and then the cleaned waste gas 8 is discharged after passing through the induced draft fan 11; The electrical switch 4 of the duct butterfly valve is wirelessly connected to the automatic temperature measuring instrument 6, and the temperature control interval value is set. When the set temperature interval is reached, the electrical switch 4 of the duct butterfly valve is opened, the induced draft fan 11 works, and the gas collecting cover 1 collects the exhaust gas 8, so that the equipment heats up to generate the exhaust gas 8 and then opens the pipeline, realizing automation and reducing the unsafe factors caused by personnel climbing up to manually open and close the pipeline butterfly valve; The automatic speed monitor 7 is wirelessly connected to the control cabinet 12, and a wind speed threshold is set. When the wind speed is lower than the set wind speed, the control cabinet 12 automatically increases the frequency of the induced draft fan 11 to achieve automatic frequency control of the induced draft fan 11, and can monitor and adjust the wind speed collected by the exhaust gas 8 of the air collecting cover 1 in real time to achieve automation.

[0019] A cross brace 14 is welded and fixedly provided at the bottom of the gas collecting cover 1 , and the automatic speed monitor 7 and the automatic temperature measuring instrument 6 are provided on the cross brace 14 .

[0020] like Figure 3As shown, the cross brace 14 supports and fixes the automatic speed detector and the automatic temperature measuring instrument 6 .

[0021] The gas collecting cover 1 is a conical structure that is narrow at the top and wide at the bottom. A guide 5 and a conduit butterfly valve electrical switch 4 are respectively provided at the connection between the gas collecting cover 1 and the exhaust gas transmission pipe 2.

[0022] like Figure 2 As shown, the gas collecting cover 1 has a conical structure that is narrow at the top and wide at the bottom, which is beneficial for the centralized collection of the exhaust gas 8; The guide 5 is a functional structural component of the pipeline support and hanger, which supports and limits the pipeline.

[0023] An air guide plate 9 is provided at the middle position of the air inlet end at the bottom of the air collecting cover 1. Both ends of the air guide plate 9 are welded to the cross brace 14 so that the exhaust gas 8 enters from the edge of the air collecting cover 1 to increase the air inlet velocity.

[0024] like Figure 3 As shown, the air guide plate 9 is helpful to increase the wind speed around the air collecting cover 1, increase the air inlet speed, and improve the collection efficiency of the exhaust gas 8.

[0025] The working process of the present invention is as follows: when the present invention is in use, the induced draft fan 11 is controlled to work, and the waste gas 8 enters the waste gas transmission pipe 2 through the gas collecting cover 1. Since the induced draft fan 11 is arranged at the rear ends of the activated carbon absorption box 3 and the ultraviolet light box 10 and connected through a pipeline, the waste gas 8 enters the activated carbon absorption box 3 through the waste gas transmission pipe 2, and the large particles in the waste gas 8 are adsorbed by the activated carbon, and then enters the ultraviolet light box 10 to photolyze the waste gas 8 by ultraviolet light, and the waste gas 8 is irradiated with ultraviolet light beams to crack the molecular chains of organic or inorganic high molecular weight evil compounds in the industrial waste gas 8, degrade them and transform them into low molecular weight compounds, and then the cleaned waste gas 8 is discharged after passing through the induced draft fan 11; The electrical switch 4 of the duct butterfly valve is wirelessly connected to the automatic temperature measuring instrument 6, and the temperature control interval value is set. When the set temperature interval is reached, the electrical switch 4 of the duct butterfly valve is turned on, the induced draft fan 11 works, and the gas collecting cover 1 collects the exhaust gas 8, so that the equipment heats up to generate the exhaust gas 8 and then opens the pipeline, realizing automation and reducing the unsafe factors caused by personnel climbing up to manually open and close the pipeline butterfly valve; The automatic speed monitor 7 is wirelessly connected to the control cabinet 12, and a wind speed threshold is set. When the wind speed is lower than the set wind speed, the control cabinet 12 automatically increases the frequency of the induced draft fan 11 to achieve automatic frequency control of the induced draft fan 11, and can monitor and adjust the wind speed collected by the exhaust gas 8 of the air collecting cover 1 in real time to achieve automation.
