Description

Technical Field

[0001] This utility model belongs to the field of environmental protection testing equipment technology, and specifically relates to a novel dust concentration generating device. Background Technology

[0002] Current mainstream online dust monitoring products require high-temperature vaporization pretreatment of sampled high-humidity dust to eliminate the influence of droplets on measurements. Various monitoring products require factory calibration, but manufacturers often struggle to provide high-humidity, low-concentration operating conditions as factory testing environments, rendering factory calibration meaningless and affecting the effectiveness of the instruments in field use. Furthermore, devices using optical methods are highly sensitive to dust color and particle size, and these indicators vary significantly under different operating conditions, all of which pose challenges to the metrology of online dust monitoring equipment. How to simulate a precise and controllable dust concentration environment for better calibration of online monitoring equipment has become a key challenge in the industry.

[0003] Chinese utility model patent CN201310140290.5 discloses a dust environment simulation device, including a dust generator, a wind tunnel, a dust collector, and a fan. This simulation device can simulate a dust environment with uniform concentration, and the concentration is adjustable. Testing products using this simulation device yields more accurate test results. However, this device can only simulate a stable dust environment, making quantitative analysis difficult, and its large size makes it difficult to make portable.

[0004] In summary, existing technical solutions suffer from problems such as difficulty in accurately quantifying dust concentration, lack of portability, and complex equipment manufacturing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel dust concentration generating device. This device features a simple and reasonable structure, is easy to control, and is highly practical. The atomizer is not easily clogged, and it embodies the process of wet desulfurization generating particulate matter. As a calibration device for ultra-low emission monitoring equipment for flue gas particulate matter, it is reliable and effective.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel dust concentration generating device includes a reactor, a jet pump, a dilution pipe, an atomizing device, and a tank. The tank is divided into a diffusion zone, a measurement zone, and a polymerization zone from top to bottom. The reactor and the atomizing device are installed on the top of the tank. The atomizing nozzle of the atomizing device extends into the reactor. The reactor is also connected to the jet pump. The outlet of the jet pump is connected to the diffusion zone of the tank through the dilution pipe. A discharge pipe is provided at the bottom of the polymerization zone.

[0008] In this invention, the reactor, dilution pipe, diffusion zone, measurement zone, polymerization zone, and discharge pipe constitute a top-down transmission system involving the generation, diffusion, and discharge of dust; wherein, the atomizing device is placed between the reactor and the diffusion zone, and generates two atmospheres through atomization or other reactions to mix in the reactor and undergo new chemical reactions to generate suspended particulate matter components.

[0009] As a further explanation of this utility model, the jet pump is connected to a flow meter; the flow meter controls the flow of clean compressed air into the jet pump to generate negative pressure, driving the suspended components in the reactor to conduct and diffuse from top to bottom.

[0010] Furthermore, the jet pump has a straight-through structure, which facilitates the effective mixing of dilution gas (flow rate of Qd L / min) and suspended particles, allowing the mixed gas to be conducted from top to bottom, wherein the flow rate of the dilution gas should be greater than the sampling flow rate of the sampling device.

[0011] As a further explanation of this utility model, the reactor is a detachable transparent glass cover, which facilitates visual inspection of the mixing and reaction of atomized droplets in the reaction zone to produce suspended particles.

[0012] As a further explanation of this utility model, the atomizing device includes atomizing device I and atomizing device II; atomizing device I is used to atomize Ca(OH)2 solution (concentration of Qc mol / mL) into suspended droplets and conduct them into the reactor; atomizing device II is used to atomize dilute sulfuric acid solution (concentration of Qh mol / mL) into suspended droplets and conduct them into the reactor.

[0013] As a further explanation of this utility model, the diffusion region has a variable diameter structure that is narrow at the top and wide at the bottom, so that the mixed gas is conducted and diffused from top to bottom.

[0014] As a further explanation of this utility model, the aggregation zone and the discharge pipe form a convergent structure, which does not affect the particle distribution in the measurement zone and removes waste gas.

[0015] As a further explanation of this utility model, the tank in the measuring area is also provided with an observation window.

[0016] As a further explanation of this utility model, the tank body in the measuring area is also provided with embedded flange I and embedded flange II. Embedded flange I can be used to install fixed reference equipment or as a comparison hole for weighing comparison; embedded flange II can be used to install the equipment to be calibrated.

[0017] As a further explanation of this utility model, the atomization rate of both atomizing device I and atomizing device II is VnmL / min, the solubility of the Ca(OH)2 solution is Qc mol / mL, and the flow rate of the dilution gas in the jet pump is Qd L / min. Therefore, the final effective particulate matter concentration C mg / m³ satisfies the following formula:

[0018] C=(137*Vn*Qc) / (Qd / 1000).

[0019] This invention can effectively generate particulate matter concentration by controlling the concentration of the atomizing component, the atomization speed, and the flow rate of the flow meter.

[0020] Advantages of this utility model:

[0021] The device of this utility model has a simple and reasonable structural design, is easy to control, and is highly practical. The atomizer is not easily clogged, and it realizes the process of wet desulfurization generating particulate matter. As a calibration device for ultra-low emission monitoring equipment of flue gas particulate matter, it is reliable and effective. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings. Example

[0025] A novel dust concentration generating device, such as Figure 1 As shown: It includes a reactor 1, a jet pump 2, a dilution pipe 3, an atomizing device, and a tank; the tank is divided into a diffusion zone 6, a measurement zone 7, and a polymerization zone 8 from top to bottom; the reactor 1 and the atomizing device are installed on the top of the tank; the atomizing nozzle of the atomizing device extends into the interior of the reactor 1; the reactor 1 is also connected to the jet pump 2; the outlet of the jet pump 2 is connected to the diffusion zone 6 of the tank through the dilution pipe 3; and a discharge pipe 11 is provided at the bottom of the polymerization zone 8.

[0026] Furthermore, the jet pump 2 is connected to a flow meter; the flow meter controls the flow of clean compressed air into the jet pump 2 to generate negative pressure, driving the suspended components in the reactor 1 to conduct and diffuse from top to bottom.

[0027] Furthermore, the jet pump 2 has a straight-through structure, which facilitates the effective mixing of dilution gas and suspended particles, allowing the mixed gas to be conducted from top to bottom.

[0028] Furthermore, the reactor 1 is a detachable transparent glass cover 3, which facilitates visual inspection of the mixing and reaction of atomized droplets in the reaction zone to produce suspended particles.

[0029] Furthermore, the atomizing device includes atomizing device I4 and atomizing device II5; atomizing device I4 is used to atomize Ca(OH)2 solution into suspended droplets and conduct them into the reactor 1; atomizing device II5 is used to atomize dilute sulfuric acid solution into suspended droplets and conduct them into the reactor 1.

[0030] Furthermore, the diffusion region 6 has a variable diameter structure that is narrow at the top and wide at the bottom, allowing the mixed gas to be conducted and diffused from top to bottom.

[0031] Furthermore, the aggregation zone 8 and the discharge pipe 11 form a convergence structure that does not affect the particulate matter distribution in the measurement zone and removes waste gas.

[0032] Furthermore, the atomization rates of both atomizing device I4 and atomizing device II5 are Vn mL / min, the solubility of the Ca(OH)2 solution is Qc mol / mL, and the flow rate of the dilution gas in the jet pump 2 is Qd L / min. Therefore, the final effective particulate matter concentration C mg / m³ satisfies the following formula: C = (137 * Vn * Qc) / (Qd / 1000).
