A steam recovery system for a corrugated cardboard production line

Abstract

The invention discloses a steam recycling system for a corrugated paper board production line. The steam recycling system mainly solves the technical problem that the temperature of steam output fromthe interior of a first-level preheating cylinder is too high, and consequently, the subsequent product quality is lowered. According to the technical scheme, the steam recycling system is characterized by comprising a steam furnace and a main steam outlet pipe connected with the steam furnace, the main steam outlet pipe is connected with a tile wheel roller, a first-level preheating cylinder matched with a single tile machine, and a second-level preheating cylinder matched with a paper pasting machine, wherein the tile wheel roller, the first-level preheating cylinder and the second-level preheating cylinder are sequentially connected in series; the second-level preheating cylinder is connected with a main steam return pipe connected with the steam furnace, and an adjusting device for adjusting the temperature of the steam entering the second-level preheating cylinder is connected between the first-level preheating cylinder and the second-level preheating cylinder. The adjusting device can adjust the temperature of the steam entering the second-level preheating cylinder. When it is found that the temperature of the steam is too high, the adjusting device can reduce the temperatureof the steam, the situation that after the water in paper boards is excessively evaporated, the bonding effect is not good is avoided, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to a corrugated cardboard production equipment, more specifically, it relates to a corrugated cardboard production line steam recovery system. Background technique [0002] Corrugated cardboard production line, referred to as corrugated line, is the key production equipment of corrugated box production enterprises. Corrugated cardboard production line is the most important production line equipment in carton packaging enterprises, including several important components such as wet end equipment, cadre equipment, and production management system. The wet end equipment in the whole corrugated board production line is the key equipment for corrugated forming. As an important heating device in the wet end equipment, the preheater needs to consume a large amount of steam. In the commonly used preheater equipment at present, a large amount of steam is directly discharged after passing through the preheater, which causes waste of steam ...

Problems solved by technology

[0004] However, in actual use, when the steam is output from the first-stage preheating cylinder, the temperature of the steam is still high, and the steam is directly input into the second-stage preheating cylinder, resulting in an excessively high surface temperature of the second-stage preheating cylinder. It will lead to excessive evaporation of the moisture in the single-tile board and the inner paper entering the paper paste machine. Since the single-tile board and the inner paper are bonded by paper paste, the single-tile board and the inner paper are too dry, which will reduce the single-tile The bonding effect of the board and the inner paper
