Abstract
The invention discloses a papermaking ventilating system. The papermaking ventilating system comprises a steam cover, a heat recovery device, an air feeder, an exhaust fan, and a steam heater; the steam cover is communicated with the heat recovery device through a pipeline; the air feeder is communicated with the steam cover; the exhaust fan is communicated with the heat recovery device; the heat recovery device is communicated with the steam heater; and the steam heater is communicated with the air feeder. After being filtered, outdoor fresh air at normal temperature enters the residual heat recovery device, after the air is exhausted and preheated by the steam cover at the temperature of 78 DEG C, the temperature of the air reaches 45 to 60 DEG C, the temperature of the air is further raised to be 110 DEG C by the steam heater, the air is fed into a bottom steam cover and a bag ventilator by the air feeder, and the exhaust efficiency is improved, so that the production efficiency of paper is improved.
Description
Technical field
The present invention relates to field of energy-saving technology, particularly relate to the papermaking ventilating system.
Background technology
In the technological process of papermaking, drying section need be replaced a large amount of steam and discharge by ventilating system, reaches the purpose of oven dry paper.Because the vapour cover cost of closed is very high, in order to save cost, selects for use the closed vapour cover of plain type relatively to conform with rule.The steam discharge water capacity of vapour cover is generally at 0.1～0.12kg water/kg dry air, delivery temperature is generally 60～70 ℃ of dry-bulb temperatures, 54～58 ℃ of wet-bulb temperature, the every evaporation of paper 1kg water need be discharged the above air of 20kg in this vapour cover, because sealing is poor, the air leak rate of air curtain height has influence on production efficiency, and be easy to generate paper defects, reduced the performance of finished paper.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art and a kind of papermaking ventilating system is provided.
Purpose of the present invention realizes by following technical measures.
The papermaking ventilating system comprises vapour cover, heat reclamation device, pressure fan, exhaust blower and steam heater; Described vapour cover and heat reclamation device pass through pipeline connection, described pressure fan is connected with described vapour cover, described exhaust blower is connected with described heat reclamation device, and described heat reclamation device is communicated with described steam heater, and described steam heater is connected with described pressure fan.
Described heat reclamation device also is provided with the air intake pipe, and described air intake pipe is equipped with filter.
Also comprise the spray equipment that is installed on described heat reclamation device.
On the connecting pipe of described heat reclamation device and vapour cover valve is installed.
Described heat reclamation device is set to two, and these two heat reclamation devices are connected with same steam heater.
The present invention makes the outdoor fresh air of normal temperature enter waste-heat recovery device after filtering, after 78 ℃ vapour cover air draft preheating, temperature reaches 45～60 ℃, further improve temperature to 110 ℃ through steam heater again, be transported to bottom vapour cover and bag ventilator by pressure fan, improve steam discharge efficient, thereby improved the production efficiency of paper.
Description of drawings
The present invention will be further described to utilize accompanying drawing, but the content in the accompanying drawing does not constitute any limitation of the invention.
Fig. 1 is the structural representation of an embodiment of papermaking ventilating system of the present invention.
The specific embodiment
The invention will be further described with the following Examples.
An embodiment of papermaking ventilating system of the present invention comprises vapour cover 1, heat reclamation device 2, pressure fan 3, exhaust blower 4 and steam heater 6 as shown in Figure 1; Described vapour cover 1 passes through pipeline connection with heat reclamation device 2, described pressure fan 3 is connected with described vapour cover 1, described exhaust blower 4 is connected with described heat reclamation device 2, and described heat reclamation device 2 is communicated with described steam heater 6, and described steam heater 6 is connected with described pressure fan 3.
Described heat reclamation device 2 also is provided with the air intake pipe, and described air intake pipe is equipped with filter 7.
Present embodiment also comprises the spray equipment 5 that is installed on described heat reclamation device 2.
On the connecting pipe of described heat reclamation device 2 and vapour cover 1 valve is installed.
Described heat reclamation device 2 is set to two, and these two heat reclamation devices 2 are connected with same steam heater 6.
Should be noted that at last; above embodiment only is used to illustrate technical scheme of the present invention but not limiting the scope of the invention; although the present invention has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the essence and the scope of technical solution of the present invention.
