Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of furnace gas purification of calcium carbide furnaces, in particular to a furnace gas purification and temperature regulating device. Background Art
[0002] The furnace gas purification design requires that the furnace gas enters the bag dust collector after passing through the three-stage purification device, and the temperature is between 225 and 260°C. Because the furnace gas contains trace tar, when the furnace temperature is too low, the tar will precipitate and adsorb on the equipment and the inner wall of the pipeline and the dust collector bag, which not only affects the normal operation of the system equipment, but also the tar adsorbs on the surface of the filter bag to reduce its air permeability, and finally leads to the loss of filtering function. If the furnace temperature is too high and enters the bag dust collector, the filter bag will be burned and the dust removal effect will not be achieved. Therefore, the furnace gas temperature needs to be controlled within a safe range of 225 to 260°C before entering the bag dust collector. Utility Model Content
[0003] The utility model aims to provide a furnace gas purification and temperature regulating device, which is used to solve the problems mentioned in the prior art in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a furnace gas purification and temperature control device, comprising a second-stage cooler pipe and a third-stage cooler pipe, a jumper pipe is provided between the second-stage cooler pipe and the third-stage cooler pipe, one end of the jumper pipe is connected to the inlet of the second-stage cooler pipe, and the other end of the jumper pipe is connected to the outlet of the third-stage cooler pipe, and valves are provided on the second-stage cooler pipe and the jumper pipe.
[0005] Furthermore, the second-stage cooler pipeline and the jumper pipeline are both provided with an expansion joint located above the valve.
[0006] Furthermore, the valve is specifically a double water-cooled butterfly valve.
[0007] Furthermore, the outlet of the third-stage cooler pipeline is connected to a bag filter pipeline.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0009] The utility model has the following beneficial effects:
[0010] When the furnace gas temperature at the inlet of the bag filter pipe is lower than the designed minimum temperature, the valve on the jumper pipe is automatically opened, and the valve on the second-stage cooler pipe is closed, that is, the furnace gas temperature at the inlet of the bag filter pipe is increased by reducing the amount of furnace gas entering the second-stage cooler pipe; conversely, when the furnace gas temperature is higher than the designed maximum temperature, the valve on the jumper pipe is automatically closed, and the valve on the second-stage cooler pipe is opened, that is, the furnace gas temperature at the inlet of the bag filter pipe is reduced by increasing the amount of furnace gas entering the second-stage cooler pipe;
[0011] The device maintains the bag filter inlet temperature within an appropriate range by setting up cross-over pipes and valves. BRIEF DESCRIPTION OF THE DRAWINGS
