Description

Technical Field

[0001] The invention belongs to the technical field of saturator application, and in particular relates to a saturator spraying and unblocking system. Background Art

[0002] The saturator is a deammoniation device used to purify coal gas in production. The spray saturator is generally made of acid-resistant stainless steel and has no lining. Its structure has the following characteristics: 1. The spray chamber consists of a body, an outer sleeve and an inner sleeve. A cyclone separator is formed between the outer sleeve and the inner sleeve to remove the acid mist droplets entrained in the coal gas, acting as an acid remover; 2. Two arc-shaped distribution boxes are separated between the gas inlet and the gas outlet, and nozzles are arranged in the boxes, with the direction of the nozzles facing the gas flow to form a good gas flow contact surface; 3. The lower part of the spray chamber is a crystallization classification tank, which is connected to the crystallization classification tank by a downcomer. The circulating mother liquor returns upward from the bottom of the crystallization classification tank through the downcomer, continuously generating ammonium sulfate crystals, which pass through the upwardly moving suspended ammonium sulfate mother liquor, promote the growth of crystals, and cause particle classification; 4. A mother liquid full flow pipe is arranged at the lower part of the spray chamber to control the liquid level at the lower part of the spray chamber and promote the gas to flow from the inlet to the outlet in the annular chamber.

[0003] The working principle of the spray saturator mainly involves the contact of coke oven gas with sulfuric acid spray inside the equipment, and the formation of ammonium sulfate through chemical reaction. This process includes the following key steps: 1. Structural features: The spray saturator is usually made of acid-resistant stainless steel and has no lining. Its structure includes a spray chamber, a cyclone separator, an arc distribution box, a nozzle, a crystallization classification tank, and a mother liquor full flow pipe. The spray chamber sprays sulfuric acid to the coal gas flow through the nozzle to form a good air flow contact surface, while the cyclone separator removes the acid mist droplets entrained in the coal gas.

[0004] 2. Working process: When the coke oven gas passes through the spray saturator, it is sprayed with sulfuric acid. The ammonia in the gas reacts with sulfuric acid to form neutral salt ammonium sulfate. When the sprayed sulfuric acid is excessive, acid salt ammonium hydrogen sulfate will be generated, but as the solution reaches saturation with ammonia, the acid salt will turn into neutral salt ammonium sulfate.

[0005] 3. Functional integration: The spray saturator integrates three functions: spray absorber, acid remover and crystallizer. The upper part serves as an absorber for ammonia, the middle part removes acid droplets through cyclone separation, and the lower part is an ammonium sulfate crystallizer for the generation and separation of ammonium sulfate crystals.

[0006] 4. Operation and control: By controlling the liquid level at the bottom of the spray chamber, the gas is prompted to flow in the annular chamber. At the same time, the mother liquor full flow pipe is used to adjust the liquid level at the bottom of the spray chamber to ensure good working conditions and crystal growth environment.

[0007] The spray saturator achieves effective extraction of ammonia from coke oven gas and efficient generation of ammonium sulfate through its unique structure and operation mode. The problem in the prior art is that the ammonium sulfate crystals produced in the saturator are prone to accumulate inside, affecting the circulation of the mother liquor and causing increased resistance, which is not conducive to the safe operation of the gas system; when cleaning the saturator, it is necessary to cut off the gas, shut down the machine and open the manhole for cleaning, which is inconvenient to operate. Summary of the invention

[0036] In the above scheme, the absorption chamber 1 is used for the contact between coal gas and mother liquor, and deammoniation is achieved by the reaction of mother liquor with ammonia in coal gas. The mother liquor and crystals after the reaction with coal gas enter the crystallization chamber 2 through the downcomer 4. The coal gas enters from the gas inlet pipe 9 and passes through the outer annular channel 6, the transverse channel 10, and the inner annular channel 8 in sequence before being discharged from the gas outlet pipe 7. The spray pipe 1 11 and the spray pipe 2 12 are used to connect the mother liquor pipeline, and the coal gas is sprayed through the spray pipe 1 11 and the spray pipe 2 12 to make the ammonia in the coal gas fully react with the mother liquor. The water washing pipe 1 13 and the water washing pipe 2 14 are used to connect the water source, and the crystals in the absorption chamber 1 are washed by water injection to solve the problem of hanging material and blockage inside the saturator. The cleaning effect is good for the concentrated crystals at the spray pipe 1 11 and the spray pipe 2 12. An inclined water washing pipe 1 21 is set to wash the top surface of the necking structure 3 to avoid crystal accumulation and affect the mother liquor circulation.

[0037] The water washing pipe 13 and water washing pipe 2 14 use DN50mm pipes and nozzles. The gas inlet is flushed during daily water washing to solve the problem of hanging materials. Inspection found that there was material accumulation at the mouth of the mother liquor downcomer 4 just below the inner sleeve, which prevented the mother liquor from smoothly descending to the crystallization chamber 2. During each shift of cleaning, the mother liquor downcomer 4 mouth can be cleaned through the oblique water washing pipe 1 21 and oblique water washing pipe 2 22. The main function of the saturator full flow tank is to maintain the balance of the mother liquor in the saturator, to prevent the low liquid level from causing gas overflow, and the high liquid level from causing gas channel blockage, which is crucial in the operation of the saturator.

[0038] Two DN65mm spray pipes 11 are set at the top of the saturator to increase the contact area between the primary spray and the coal gas, increase the water absorption rate of ammonia in the coal gas, and reduce the ammonia content in the coal gas after the saturator. A DN65mm spray pipe 2 12 and a nozzle are set at the top of the annular channel 6 outside the coal gas outlet, and the mother liquid spray direction is opposite to the coal gas to improve the ammonia removal effect. The water outlet ends of the oblique water washing pipe 1 21 and the oblique water washing pipe 2 22 are tilted downward by 30°-55° to flush the top surface of the shrinkage structure 3.
