Description

Waste heat utilization system of printing machine

Technical Field

The utility model belongs to the printing machine preheats the utilization field, concretely relates to printing machine waste heat utilization system.

Background

The boiler heating heat pipe heat supply that traditional printing heating used, the coal-fired heating of boiler can produce a large amount of gas pollution, and in order to protect the environment, the heating system of printing trade changes for gas or the unified steam of carrying of power plant heats more. In the solvent-based printing production, because a solvent is used, the steam of a thermal power plant is used for heating to provide a heat source for the printing machine due to safety consideration, the steam is condensed and aggregated into water after passing through the printing machine and is discharged into a fire pool, the temperature of the discharged water is usually 80-90 ℃, a large amount of heat energy is wasted, energy conservation and emission reduction are not facilitated, and how to reasonably use waste heat is realized, and energy waste is reduced.

Solvent-based printing systems are generally equipped with solvent recovery devices in order to meet environmental and energy-saving requirements. In the printing process, a large amount of volatile solvents generated by drying are conveyed into a recovery tank through a recovery pipeline, volatile gases are absorbed by activated carbon or molecular sieves in the recovery tank, the saturated activated carbon or molecular sieves are desorbed and replaced through saturated hot steam, and the volatile gases are recycled after being condensed. And every time desorption, the steam generator is used for preparing saturated steam, cold water needs to be heated into the saturated steam, the heat energy consumption is high, the recovery cost is increased invisibly, and the product cost is increased.

SUMMERY OF THE UTILITY MODEL

To foretell problem, how to reduce the energy waste that the hot water of emission produced and reduce steam generator energy consumption, the utility model provides a simple structure and can effectively solve the printing machine waste heat utilization and reduce the printing machine waste heat utilization system of steam generator's energy consumption.

In order to achieve the above object, the utility model discloses specifically adopt following technical scheme: the utility model provides a printing machine waste heat utilization system, the printing machine is furnished with solvent recovery unit and steam generator, the system includes basin, coil pipe, fire-fighting water pond, the coil pipe is located the basin, there is the water inlet basin lateral wall top, there is the delivery port basin below, and the delivery port links to each other with steam generator's entry, and steam generator's export links to each other with solvent recovery unit's steam inlet, and solvent recovery unit's condensation export links to each other with the water inlet.

Preferably, the coil is in a multiple-turn pattern.

Preferably, a valve is arranged at the water outlet.

Preferably, the inlet of the coil is at the bottom and the outlet is at the top.

Preferably, the inlet of the coil is connected to the printer vapor outlet.

Preferably, a valve is arranged at the inlet of the coil.

Preferably, a water tank is provided on a pipe between the water outlet and the inlet of the steam generator.

The utility model has the advantages as follows: the utility model discloses simple structure and can effectively solve printing machine waste heat utilization and reduce steam generator's energy consumption to realize energy saving and emission reduction, it is extravagant to reduce the energy.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: the device comprises a solvent recovery device 1, a water tank 2, a coil pipe 3, a steam generator 4, a fire pool 5, a water inlet 6, a water outlet 7, a valve 8 and a water tank 9.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. In the following description and in the drawings, the same numbers in different drawings identify the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus consistent with certain aspects of the invention, as detailed in the appended claims. Various embodiments of the present description are described in an incremental manner.

As shown in fig. 1, the utility model provides a printing machine waste heat utilization system, the printing machine is furnished with solvent recovery unit 1 and steam generator 4, the system includes basin 2, coil pipe 3, fire-fighting water pool 5, coil pipe 3 is located basin 2, there is water inlet 6 basin 2 lateral wall top, there is delivery port 7 basin 2 below, and delivery port 7 links to each other with steam generator 4's entry, and steam generator 4's export links to each other with solvent recovery unit 1's steam inlet, and solvent recovery unit 1's condensation export links to each other with water inlet 6.

In one embodiment of the present application, the inlet of the coil 3 is connected to the steam outlet of the printing press, and in order to make more use of the steam introduced into the coil 3, the coil 3 is in a multiple-turn shape, so that the coil 3 has a larger contact area with the water in the water tank 2.

In one embodiment of the present application, a valve 8 is installed at the water outlet 7 in order to control the water output of the water outlet 7.

In an embodiment of the present application, since the water outlet 7 is arranged below, the inlet of the coil 3 is below and the outlet is above, so that the temperature of the water outlet 7 is higher.
