Problems solved by technology

However, such a purification method requires high pressure for the tail gas to pass through the desulfurization tower and filter device, and the desulfurizer and desiccant need to be regenerated or replaced after long-term use, so the purification cost is high and the operation is complicated

Embodiment 1

[0031] Such as figure 1 As shown, the described semi-coke tail gas cooling and purification system includes a spray tower 10, a spiral forced landing dehumidifier 20 and a return water cooling pool 30;

[0032] The top of the spray tower is provided with an air inlet 11, the air inlet 11 is connected with the gas-collecting pipeline, and a spray plate 12 is arranged in the spray tower 10 below the air inlet 11, and the spray plate 12 below the spray plate 12 A screen plate is arranged in the shower tower; the spray plate 12 includes a fixed frame and a spiral spray pipe, the spiral spray pipe is fixed on the fixed frame, and the fixed frame is installed in the spray tower 10; the bottom of the spray tower 10 An air outlet 13 is provided, and a water outlet is provided on the spray tower wall below the air outlet 13. The water outlet is connected to a water outlet pipe 14, and a first water seal groove 15 is arranged below the water outlet pipe 14, and the lower end of the wate...

Embodiment 2

[0038] On the basis of the above-mentioned embodiment 1, further, the number of the screen plates is more than 2. By setting up multiple screens, increasing the surface area of ​​water, increasing the contact area between water and gas, and speeding up the purification and cooling speed, the impurities and soluble substances in the tail gas can be washed and settled quickly.

Embodiment 3

[0040]On the basis of the above-mentioned embodiment 1 or 2, a water inlet (not shown) is set on the tower wall of the spray tower corresponding to the spray plate; the return water cooling pool 30 is provided with an outlet pipe 33, and the outlet pipe 33 Connect with water inlet. Preferably, the outlet pipe 33 is provided with a pressure pump 34 . Through this scheme, the water in the backwater cooling pool can be pumped into the spray tower for reuse.

Abstract

The invention discloses a blue carbon tail gas cooling and purification system, which comprises a spray tower, a spiral forced-fall dehumidifier and a return water cooling pool; As a whole, when the gas is in contact with water, the impurities in the gas (such as sulfide) dissolve in the water to play the role of desulfurization, and the particulate matter is removed by the water, which plays a washing role. Discharge; in the spiral forced landing dehumidifier, the water is discharged under gravity and forced landing inertia, and the spray tower and spiral forced landing dehumidifier can also play a role in surface cooling; in the return water cooling pool, the water is in the gravity and cooling layer, The cooling effect is achieved; the water, sulfide and impurities in the treated exhaust gas are fully removed by the water, the calorific value of the gas is increased, the consumption of the gas is reduced, and the amount of sewage is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of purification and recovery of industrial waste gas, in particular to a system for cooling and purifying semi-coke tail gas. Background technique [0002] Semi-coke is fired from the high-quality Jurassic clean coal abundant in Shenfu Coalfield. As a new type of carbon material, it has high fixed carbon, high specific resistance, high chemical activity, low ash content, aluminum Low carbon dioxide, low sulfur, low phosphorus characteristics, to gradually replace metallurgical coke and widely used in the production of calcium carbide, ferroalloy, ferrosilicon, silicon carbide and other products, becoming an irreplaceable carbon material. [0003] The process of producing semi-coke will produce more combustible tail gas. The semi-coke tail gas treatment method is generally direct combustion treatment, resulting in a great waste of energy and environmental pollution. In order to make full and reasonable use ...
