Problems solved by technology

[0005] 1. The heat exchanger used adopts longitudinal fins, which is difficult to process, and the heat exchange tubes are arranged in a triangular shape staggered up and down. In this way, in order to ensure the smooth flow of active coke, the number of heat exchange tubes per unit volume must be arranged less, resulting in the overall device Generally relatively large, high investment in equipment
At the same time, the longitudinal

Embodiment 1

[0051] Steam is used as the desorption heat source, that is, the heat source system 10 is heated by steam. The heating heat exchanger 41 adopts Image 6 In the shown structure, the steam in the heating chamber 4 enters directly from the inlet 72 of the heating heat exchanger, and goes out from the outlet 71 of the heating heat exchanger. The used steam is medium-pressure steam, which is used for industrial production according to the actual needs of the project. The cooling medium in the cooling chamber 7 is heated when cooling the active coke, and enters the air inlet 52 of the preheating heat exchanger from the outlet 61 of the cooling heat exchanger, and the active coke is preheated in the preheating chamber 2, and the medium is cooled at the same time. The external circulating medium heat exchanger 11 is further cooled to obtain a lower temperature, and circulates into the cooling chamber 7 through the circulation pump 12 . In thermal cycling, the medium can be inert gas ...

Embodiment 2

[0056] Electricity is used as the desorption heat source, that is, the heat source system 10 is electric heating, and the heating chamber heat exchanger 41 adopts image 3 The structure shown is the same as that of Embodiment 1. In this way, the heat exchange medium coming out of the outlet 71 of the heating heat exchanger of the heating chamber 4 directly enters the heat source system 10 for electric heating, and the temperature is raised to about 500° C. by the electric heater. The gas outlet 72 of the heating heat exchanger enters the heating chamber 4 to heat the active coke to reach the desorption temperature. The heat exchange medium can be air or inert gas. The sealing of the device and the extraction of the desorption gas are the same as in Example 1.

[0057] In this patent, if the corresponding heat exchangers (preheating heat exchanger 21, heating heat exchanger 41, and cooling chamber heat exchanger 73) in the preheating chamber 2, heating chamber 4, and cooling c...

Abstract

The invention discloses a movable desorption device of activated coke. An inlet blocking valve, a heating chamber, a reaction chamber, a cooling chamber and an outlet blocking valve are sequentially connected from top to bottom in the reactor main body; the heating chamber is provided with a heating heat exchanger therein which is connected with a thermal source device; a cooling heat exchanger is arranged in the cooling chamber; a preheating chamber is arranged between the inlet blocking valve and heating chamber and provided with a preheating heat exchanger, which forms a heat circulating system with a circulating medium heat exchanger, a circulating pump and the cooling heat exchanger; a first cloth gas guide mechanism is arranged between the preheating chamber and heating chamber; a second cloth gas guide mechanism is arranged between the heating chamber and reaction chamber; and the first and second cloth gas guide mechanisms are respectively connected with a gas recovery suction pump for recycling desorption gas. The invention has higher utility ratio of heat energy by redesigning each part in the reactor, and has more complete air suction, higher desorption efficiency and less corrosion to devices by adding the cloth gas guide mechanisms.

Description

Technical field: [0001] The invention relates to a device for desorbing active coke that has adsorbed sulfur dioxide, recovering SO2 resources, and restoring the performance of active coke, specifically a mobile desorption device for active coke. Background technique: [0002] my country's primary energy is mainly coal, and the flue gas and waste gas discharged from coal-fired power plants, metal smelters, coal-fired boiler plants, waste incineration and other industrial furnaces contain SO 2 , SO 3 , NO, heavy metal ions, harmful smoke and dust pollutants, thus forming serious pollution, affecting our production and life, the situation is very grim; my country is also a large agricultural country and needs a large amount of sulfuric acid and sulfur to produce fertilizers, but our country is poor in sulfur and can only produce fertilizers every year Spend huge sums of money to import sulfur from abroad; moreover, my country's coal resources are mostly distributed in water-de...
