DETAILED DESCRIPTION

[0025] The device of the present invention is described in detail below in conjunction with the accompanying drawings, and a specific implementation plan is given based on the premise of the present invention.

[0026] The intelligent integrated multi-pollutant and greenhouse gas comprehensive coordinated treatment equipment is a movable integrated equipment, which is easy to transport.

[0027] An intelligent integrated multi-pollutant and greenhouse gas comprehensive coordinated treatment equipment consists of six areas; including a control area 1, a pretreatment area 2, a desulfurization area 3, a demisting area 4, a VOCs purification area 5, and an alkaline solution area 6; the control area 1, the pretreatment area 2, the desulfurization area 3, the demisting area 4, the VOCs purification area 5, and the alkaline solution area 6 are integrated and installed on a movable device.

[0028] The control area 1 includes a control cabinet 7, a desulfurization pump 9, a backwashing pump 8, and a tool box 29; the control cabinet 7 is connected to the pretreatment area 2, the desulfurization area 3, the demisting area 4, the VOCs purification area 5, and the alkali solution area 6.

[0029] The control panel of the control cabinet 7 can display in real time the gas pressure between various areas, the liquid pressure on each pipeline, the operating status of the pump, the real-time emission data of solid particles, sulfides, and VOCs at the exhaust outlet, etc., which is convenient for unified monitoring. The above information can also be output to external devices for display through the signal interface.

[0030] The pretreatment area 2 includes a pretreatment area flushing pipe network 11 , a pretreatment area flat plate demister 12 , a gravity dust collector 10 , and a sewage collection tank 13 .

[0031] The pretreatment area 2 adopts a multi-layer design. The bottom layer is the pre-dust removal area. It adopts an F-shaped porous bent double-layer airflow distribution plate to achieve uniform airflow distribution within a limited height, while effectively intercepting particulate matter, liquid water, etc. in the exhaust gas. The middle layer is the fine dust removal area. By adjusting the spacing of the multi-layer flat plate demisters and controlling the gas flow rate, small particles and small droplets can be further removed. The top layer is the backwash layer composed of a flushing pipe network. Different liquids such as water and oil can be used for corresponding backwashing according to different exhaust gas components to ensure the long-term and stable operation of the pre-dust removal area and the fine dust removal area.

[0032] The desulfurization zone 3 includes an air flow distribution plate 14 , a spray pipe network 15 , a desulfurization zone guide plate 16 , and a slurry collection tank 17 .

[0033] The nozzle setting is more reasonably optimized for the square area, which makes the spray atomization effect better, increases the contact time and contact area between the waste flue gas and the alkali solution within a limited height, and improves the desulfurization efficiency.

[0034] The demisting area 4 includes a coalescer 18 , a demisting area flat plate demister 19 , a wire mesh demister 20 , a demisting area flushing pipe network 21 , a demisting area guide plate 22 , and a flushing water collection tank 23 .

[0035] The flat-plate demister is arranged on the lower layer, which has good demisting effect and removes most of the small droplets; the wire mesh demister is arranged on the middle layer, which effectively absorbs the small droplets escaping from the flat-plate demister; the coalescer is arranged on the upper layer to further efficiently separate the entrained solid particles and tiny droplets; the spacing between the upper, middle and lower demister devices is rationally arranged to ensure the demisting effect of each layer; the flushing pipe network is reasonably set according to the structure of the demister device to ensure the flushing coverage area and have a significant cleaning effect.

[0036] The VOCs purification area 5 adopts a multi-layer honeycomb activated carbon adsorption layer 26, which is arranged in a drawer type. The activated carbon can be replaced as a whole on both sides of the device to achieve VOCs purification.

[0037] An online exhaust gas detection instrument 24 is provided at the top exhaust gas outlet of the VOCs purification zone 5, which can feed back flue gas parameters such as solid particles, sulfides, VOCs, etc. in the exhaust gas to the control panel of the control zone in real time, so as to monitor the operation of the entire device in real time on site.

[0038] The alkali solution area 6 includes an alkali solution storage tank 27 , in which an agitator 26 is arranged.

[0039] The alkali liquid area is used as a container to store alkali liquid. Liquid alkali can be directly put into this area through an alkali tank truck, and solid alkali flakes can also be put in. The concentration is adjusted by injecting water. Agitators, drain ports, liquid level detectors, and pH meters are installed in this area.

[0040] Embodiment 1: According to transportation restrictions, the length of this device is ≤18 meters, the width is ≤2.5 meters, and the height is ≤2.8 meters. The device can be divided into multiple specifications such as flue gas treatment capacity of 10000m³ / h, 8000m³ / h, 5000m³ / h, etc., which belongs to serialized equipment. The device is transported to the destination for unloading and fixing, and the flue gas pipeline is connected to the process pipeline. The inlet of the pretreatment area 1 is connected to the inlet of the industrial waste flue gas, the outlet of the VOCs purification area 5 is connected to the outlet of the industrial waste flue gas, the outlet of the desulfurization pump 9 is connected to the spray pipe network of the desulfurization area 3, and the outlet of the backwash pump 8 is connected to the flushing pipe network of the pretreatment area 1 and the demisting area 4 to form a backwash layer of the demister. The inlet of the desulfurization pump 9 is connected to the outlet of the alkali liquid area 6 through a pipeline, and the inlet of the backwash pump 8 is connected to the process water pipeline provided by the plant area. After the industrial waste flue gas enters the device, it first passes through the pretreatment area 1 for demisting and dust removal, then enters the desulfurization area 3 to remove sulfides. The flue gas contacts the spray layer in countercurrent, then enters the demisting area 4 to remove droplets and tiny particles, and then enters the VOCs purification area 5 to remove VOCs gas. The flue gas that has been purified and meets the standards is discharged through the industrial waste flue gas outlet pipe.

[0041] Example 2: This device is suitable for treating 10,000 m³ of flue gas. If the flue gas volume increases by 50,000 m³, 5 identical intelligent integrated multi-pollutant comprehensive coordinated treatment devices can be implemented in parallel. The flue inlet main pipe is divided into 5 branch pipes and enters the equipment respectively. After the flue gas is purified, it enters the flue outlet main pipe through the 5 branch pipes and meets the emission standards.

[0042] The device of the present invention can effectively solve the problem of difficult treatment of multiple pollutants through intelligent integrated design, and the device has short installation and construction time, low cost, convenient transportation, and small footprint. It has good effects for different flue gas conditions, and has great advantages in construction period, cost, and use effect compared with large-scale construction, design of large-scale reaction towers and other engineering projects.

[0043] In summary, the above embodiments are all different cases implemented based on the design of the present invention, but the protection scope of the patent of the present invention is not limited thereto. Any engineer familiar with the technical field who makes improvements to the design content should be included in the protection scope of this invention patent.
