[0003] And some production enterprises also produce high-temperature acid waste gas. If the high-temperature waste gas is discharged directly through the spray tower, the high temperature will cause the neutralizing agent to evaporate quickly, which not only reduces the effective utilization rate of the neutralizing agent, but also increases the cost of the production enterprise. , and the rapidly evaporating neutralizing agent will form crystals, which will block the packing layer and make the spray tower invalid. After the packing layer is blocked, the waste gas may flow back, and if it is serious, it will damage the production equipment and bring huge economic losses to the production enterprise. loss
In addition, the filler (generally made of plastic) that plays a role in mass transfer in the filler layer is prone to aging if it works in a high temperature environment for a long time, and frequent replacement of the filler will affect the production progress
[0004] Therefore, before passing through the packing layer of the spray tower, it is necessary to dissipate heat from the high-temperature exhaust gas. Heat dissipation, but the heat dissipation capability of the heat sink is effective, in practical applications, its heat dissipation effect is not ideal
In others, when the high-temperature exhaust gas is passed into the spray tower, cold air is introduced at the same time, and the temperature of the exhaust gas is reduced by mixing the cold air with the high-temperature exhaust gas. However, the gas displacement of the spray tower has a certain limit. After mixing the cold air, the exhaust gas It only accounts for the part of the mixed gas, which undoubtedly reduces the efficiency of the spray tower to treat the exhaust gas

The piston type double-tube refrigerant heat dissipation exhaust gas spray tower comprises an exhaust gas inlet, a tower body and a packing layer, wherein a double-tube refrigerant heat dissipation device is arranged in the tower body and is arranged between the exhaust gas inlet and the packing layer; the double-tube refrigerant heat dissipation device comprises a first refrigerant heat dissipation tube, a second refrigerant heat dissipation tube, a first piston assembly, a second piston assembly and a crankshaft; each of the first piston assembly and the second piston assembly comprises a sealing piston and a piston connecting rod; when the crankshaft rotates, the first piston assembly can perform stretching actions and retracting actions alternately in the first refrigerant heat dissipation tube, and the second piston assembly can perform stretching actions and retracting actions alternately in the second refrigerant heat dissipation tube, so as to achieve an effect of efficiently dissipating heat of high-temperature exhaust gas introduced into the tower body.
Description
technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a piston-type double-tube refrigerant heat dissipation waste gas spray tower. Background technique [0002] Many production industries will produce acidic industrial waste gas in the industrial production process. In order to meet the emission standards and reduce environmental pollution, it is necessary to carry out acid removal treatment for the acidic waste gas. The common practice is to pass the acidic waste gas through the spray tower. The neutralizing agent is circulated and sprayed into the packing layer in the tower, so that the acid waste gas reacts with the neutralizing agent when passing through the packing layer, thereby reducing the acidity of the waste gas. [0003] And some production enterprises also produce high-temperature acid waste gas. If the high-temperature waste gas is discharged directly through the spray tower, the high temperatur...
