Single-end-face tube dryer

Abstract

The invention provides a single-end-face tube dryer which comprises a rack, multiple drying tubes, a discharging device, a heat supply device and a material distribution device. The multiple drying tubes are arranged on the rack at intervals; the discharging device is arranged on the rack and reciprocates along the drying tubes so as to clean dried materials on the drying tubes; the heat supply device is communicated with the drying tubes and supplies steam into the drying tubes; the material distribution device is arranged on the rack and located above the drying tubes; and through the multiple drying tubes, the area of the drying face can be remarkably increased, and the heating and drying area can be increased by ten times under the same size, so that the drying and curing efficiency isimproved. The discharging device reciprocates along the drying tubes so as to clean the dried materials on the drying tubes, the drying tubes do not need to rotate in the cleaning process, the running path of a heating medium is changed, and moving parts with the high failure rate such as a rotary steam connector are omitted, so that the stability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of landfill leachate and high-salt wastewater treatment, in particular to a single-end surface tube dryer. Background technique [0002] At present, landfill leachate and high-salt wastewater crystallization mother liquor lack effective concentration and solidification equipment. Most enterprises temporarily use equipment such as spray drying, evaporation kettle, submerged combustion, and drum scraper dryer for concentration and drying treatment. Spray drying is to enter the hot air at the bottom of a cylinder, and spray the material to be dried from the nozzle at the top. The two go towards each other. As a result, the water is evaporated and the curing process is completed. This method consumes too much energy, which is about the average value of other methods. It is about 1.5 times that of spray drying process. At the same time, the waste gas emission of spray drying process is huge, which actually increases new po...

Problems solved by technology

[0003] Among the above-mentioned methods, the drying method of the drum scraper dryer is currently the best method, but the drying efficiency of a single machine is low, and the specification on sale can process about one ton per hour, and the volume is relatively huge, occupying a large area, and the manufacturing cost High cost, many dynamic running parts, many wearing parts, relatively high failure rate
