Description

A high pressure water mist Venturi tube

technical field

The utility model relates to a cooling and dedusting device, in particular to a high-pressure fine water mist Venturi tube.

Background technique

In recent years, with the rapid development of China's economy, the energy consumption mainly composed of coal continues to increase, and the soot and SO ₂ discharged into the atmosphere are also increasing. According to statistics, in 1997, China's dust emissions reached 18.73 million tons, and SO ₂ emissions reached 23.46 million tons. Soot and SO ₂ have caused serious air pollution. Therefore, economical and effective technical measures must be taken to control the emission of harmful gases such as soot and SO ₂ . Wet scrubber is a very important type of gas purification equipment. Among them, Venturi scrubber has the highest efficiency and can be used to remove dust particles and gaseous pollutants with a particle size of less than 0-11μm. The dust removal efficiency can reach 99%, and the desulfurization efficiency can reach 90%. Moreover, it is inexpensive, simple in construction (no moving parts), and capable of handling wet and corrosive gases. However, its high capture rate for fine dust and sulfur dioxide is at the cost of the energy and gas pressure loss provided, so its improvement and innovation are imperative.

Contents of the invention

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide a high-pressure water mist Venturi tube, which can effectively solve the problem of cooling and dust removal in the process of dusty gas discharge.

The technical scheme solved by the utility model is a high-pressure fine water mist Venturi tube, including a water tank, a high-pressure pump and a Venturi tube. The water outlet of the water tank is connected with the water inlet of the high-pressure pump. The outlet end of the pipeline extends into the straight pipe section with a smaller diameter of the Venturi tube (also known as the Venturi tube), and the end of the extension is equipped with a high-pressure fine water mist nozzle.

The utility model is novel and unique in structure, simple and reasonable, easy to produce, low in cost, and low in water consumption. The flue gas or fine water mist is combined to form large particles of mist and fall down. The entire pipeline can be a dust-reducing area, making full use of the space. Resources, significantly shorten the pipeline, good effect of cooling and dust removal, easy to use, and have good social and economic benefits.

Detailed ways

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

Provided by Fig. 1-2, the utility model comprises water tank, high-pressure pump and Venturi tube, and the water outlet of water tank 4 links to each other with the water inlet of high-pressure pump 5, and stainless steel pipe 3 is housed on the water outlet of high-pressure pump 5, and the stainless steel pipe 3 The outlet end extends into the straight pipe section 12 with a smaller diameter of the Venturi tube 1, and a high-pressure fine water mist nozzle 2 is installed on the end portion extending into it.

In order to ensure the use effect, the high-pressure fine water mist nozzle 2 is fixed in the straight pipe section 12 of the Venturi tube 1, and the spray direction of the high-pressure fine water mist nozzle is consistent with the flow direction of the dusty gas; the high-pressure fine water mist nozzle 2 is the "ultra-fine water mist nozzle" with the patent number "200610017940.7" previously applied by the applicant. When the pressure is 8-16MPa, the diameter of the mist particle is 30-150μm, and the performance of attaching fine dust particles is good;

The Venturi tube 1 is a tubular integrated structure formed by successively connecting the upper transition section 11, the straight pipe section 12 and the lower transition section 13 at both ends. The large opening end of the upper gradual transition section 11 is connected to the outlet of the air intake pipe 7a, and the small opening end is connected to the outlet of the air inlet pipe 7a. One end of the straight pipe section is connected, the other end of the straight pipe section is connected with the small mouth end of the lower gradual change section 13, and the large mouth end of the lower gradual change section 13 is connected with the inlet of the air outlet pipe 7b;

The water tank 4 is located above the high-pressure pump, so that the overall structure is compact, the space occupied is small, and the installation is convenient;

The high-pressure pump 5 is connected with a controller 6, and the controller is of the prior art, and is used to control the high-pressure pump to be turned on and off.

When the utility model is in use, the high-pressure pump starts to work, and the high-pressure fine water mist nozzle 2 starts to spray fine water mist, and the flue gas (dust-containing gas) or other powder enters the Venturi tube through the intake pipe 7a, and the fine water mist directly The pipe section is mixed, and the mixed flue gas or other powder is output from the outlet pipe 7b, which achieves the effects of efficient mixing, water saving and energy saving, and efficient cooling and dust removal. Compared with the prior art, the utility model has the following advantages:

1. High-efficiency dust reduction: Fine water mist and smoke particles in the flue gas are turbulently mixed rapidly in the straight pipe section and the lower gradient section, and the combination is sufficient, and the flue gas or other powder materials are combined with water to form large droplets and fall down. , the entire pipeline can be a dust suppression area, making full use of space resources and significantly shortening the pipeline;

2. Efficient heat reduction: The fine water mist surrounds the flue gas or other powder materials, absorbs its heat and vaporizes, which can cool the materials and has a good effect of blocking radiant heat;

3. Safety and environmental protection: water is used as the treatment agent, no harmful substances will be decomposed at high temperature, no pollution to the environment, no damage to the protected objects, and no impact on human health;

4. Cost reduction: The treatment agent of this utility model is ordinary domestic water, and the interior can also achieve self-cleaning function. The water consumption is 1% of water spray, saving water resources and reducing costs. The overall equipment is made of stainless steel, which prolongs the life of the equipment. It has the advantages of safety and high efficiency, energy saving and environmental protection, convenient operation and low cost.
