The working principle of HT Jigger Dyeing Machine steam pipe

Direct (porous) steam pipes and direct (closed) steam pipes are laid at the bottom of the dyeing tank of the jigsaw dyeing machine. The direct steam pipe is used to spray steam to heat the dye solution, and the direct steam pipe is used for dyeing and heat preservation. The problem is that the direct steam pipe is a porous pipe. Even if the size of the pore size and the density of the dispersion are considered in the planning, the amount of steam and water (condensation) during heating still have great unevenness. . The main reasons are: first, steam (water) enters from one end of the tube, and the pressure in the tube is uneven, especially when the steam pressure is low; second, the condensed water in the steam will affect the uniform ejection of the steam; third, the steam injection hole It is simply blocked unevenly by the fancy dress and yarn number. Obviously, the unevenness of the spray volume of the direct heating tube must constitute the temperature difference between the left, middle and the right of the dye solution, and the unevenness of the spray water (condensate) must constitute the difference in the concentration of the dye solution.
