A mobile high-temperature smoke and dust waste gas flow field control device and process method

Abstract

The invention relates to a mobile high-temperature smoke and exhaust gas flow field control device. The control device is characterized of being of a cover body structure and comprising a flow field driving system and a heat energy flow guide system. A mobile high-temperature smoke and exhaust gas flow field control technology method comprises the following steps: enabling the flow field driving system and the heat energy flow guide system to synchronously work; keeping the flow field driving system in a negative pressure working state and keeping the heat energy flow guide system in a working state that the positive pressure is gradually reduced and the negative pressure is gradually raised; enabling environmental air flow to sequentially enter the flow field driving system; performing the positive pressure driving and the negative pressure guide driving of a smoke and exhaust gas purifying system to enable the air flow to flow into the surrounding areas of a sieve through a desulfurizer size water curtain; finally discharging the air flow into a coke tank of a coke quenching compartment for high-level desulphurization and dust removal. With the adoption of the device and technology method, the air volume of the smoke and exhaust gas purifying system can be greatly reduced, the solid and liquid particle pollution can be effectively controlled through the purifying system, and the practical significance of energy conservation, emission reduction and low operation cost is realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and is a method of using a flow field drive system and a thermal energy diversion system to control the high-temperature smoke and dust waste gas flow field with low energy consumption and small air suction volume, and simultaneously remove low-concentration SO contained in the smoke and dust waste gas. 2 The invention relates to a mobile high-temperature smoke and dust waste gas flow field control device and a process method for pollutants such as acidic components and large solid or liquid particles, and particularly relates to a mobile high-temperature smoke and dust waste gas flow field control device and process method. Background technique [0002] The smoke and dust exhaust gas purification system is mainly composed of local exhaust hoods, purification devices, piping systems and ventilators, and is currently the main and effective means of controlling smoke and dust exhaus...

AI Technical Summary

Problems solved by technology

The local exhaust hood is generally not tightly sealed, especially the contact part (especially the lower part) between the coke guide grid and the furnace door cannot be completely sealed, resulting in part of the smoke and exhaust gas escaping; the collection capacity is insufficient or uneven, resulting in Defects such as the escape of a part of smoke and dust exhaust gas from the gap between the lower edge of the local exhaust hood and the upper edge of the coke quenching car compartment (coke tank car tank mouth)

In order to solve the escape of this part of the smoke and exhaust gas, measures to increase the exhaust volume are usually adopted. In addition, since the purification device generally uses a bag filter, the cooling of the smoke and dust exhaust gas must be considered first when dealing with high-temperature flue gas and exhaust gas. Then it enters the bag filter for purification, which will lead to huge facilities for the purification system of smoke and dust exhaust gas, which does not meet the requirements of energy saving, emission reduction and low operating cost
