Combined multi-stage energy saver of equipment for recycling residual steam of waste water and waste heat

Abstract

The invention relates to the field of waste water and waste heat recycling, in particular to equipment for recycling residual steam of waste water and waste heat. The equipment is provided with an energy collector and an energy saver, wherein the energy collector and the energy saver are both of a box body structure; the energy collector is installed on the upper part of the energy saver and separated from the energy saver by a bin clamping plate; a first header, a second header, a snakelike pipe, a box body guide pipe and a waste heat guide pipe are arranged in the energy collector; an energystorage inlet device and a condensed water discharge pipe seat are arranged outside the energy collector; a left header, a right header and a snakelike pipe are arranged in the energy saver; and an energy storage discharge device and a residual steam inlet pipe seat are arranged outside the energy saver. The equipment for recycling the residual steam of the waste water and the waste heat has theadvantages of compact structure, convenient operation, smooth running of the residual steam of the waste heat, reverse movement of the energy storage and the residual steam of the waste heat, scientific heat exchange process principle, and high utilization efficiency; and the equipment has a three-stage heat exchange process to ensure the maximum utilization of the residual steam of the waste heat, and a large temperature difference between the energy storage and waste heat is always kept in the three-stage heat exchange process, so that the heat value utilization rate is fully improved, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to the field of recovery and reuse of waste heat and waste water, in particular to a combined multi-stage energy-saving device for recovery and utilization of waste heat and steam from waste water. Background technique [0002] The existing printing and dyeing industry and building materials industry such as: printing and dyeing, concrete pipe piles, aerated lime sand bricks, and aerated concrete block production lines consume about 16% of the production cost of heat. Therefore, enterprises have improved the fuel structure and adopted natural gas, light diesel oil, etc., resulting in high fuel costs. For the sake of protecting the ecological environment, it is of great practical significance to recycle the high-calorie waste heat, residual steam, and waste water discharged from the production line. The recovery efficiency of existing recycling equipment is low, and the residual steam is directly discharged into the atmosphere whi...

AI Technical Summary

Problems solved by technology

Existing recycling equipment has low recycling efficiency, and the residual steam is directly discharged into the atmosphere while still containing a lot of heat energy; it is difficult to use the waste heat and residual steam generated on the production line at the same time
