Description

Waste heat recovery device of steam circulation system

Technical Field

The utility model belongs to the technical field of acrylic resin production facility, mainly relate to and carry out the device that retrieves with the waste heat that is arranged in heating and heat retaining steam circulation system among the acrylic resin production stirring process.

Background

The production process flow of the acrylic resin is as follows: the xylene, butyl acetate and solvent are firstly put into reaction and stirring, then acrylic monomer, acrylic acid, butyl acrylate, styrene, methyl methacrylate and the like are dripped at a certain speed, and the mixture is filtered and packaged after heat preservation and curing. The heat source for keeping the temperature and heating the reaction stirring kettle generally comes from a steam circulation system. During the period of workshop shutdown, shift change and equipment maintenance, the steam circulating system stops working, and the waste heat stored in the steam coil and the heater is automatically dissipated to the outside air, so that the temperature of the workshop is increased, and the energy is wasted.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: a device capable of recovering waste heat in a steam coil and a heater is provided.

In order to solve the technical problem, the technical scheme of the utility model as follows:

the waste heat recovery device of the steam circulating system comprises a water tank and a plurality of steam pipelines; the water tank is provided with a first water outlet and a first water inlet; an independent chamber is arranged in the middle of the water tank, and the chamber is provided with a water inlet II and a water outlet II which extend to the outside of the water tank; the plurality of steam pipelines are positioned in the chamber, and the upper connector and the lower connector of each steam pipeline are respectively connected in parallel on the corresponding steam return pipe in the steam circulating system through an electromagnetic type tee joint.

According to the utility model discloses foretell steam circulation system waste heat recovery device can also have following additional technical characterstic:

further, a temperature sensor and a liquid level meter are arranged in the water tank.

Furthermore, a drainage tube communicated with the outside of the water tank is arranged on the part, located in the cavity, of each steam pipeline.

Furthermore, a plurality of steam pipelines are fixed in a base, and a plurality of radiating fins are arranged outside the base.

Furthermore, a plurality of the steam pipelines are metal corrugated pipes.

Compared with the prior art, the beneficial effects of the utility model are that: the electromagnetic three-way joint controls the on and off of a steam pipeline connected in parallel with the steam return pipe; during the period that the stirring kettle does not need to be heated and kept warm, a steam pipeline is conducted, so that heat exchange is carried out on hot steam in a water tank, and the recovery of steam waste heat is realized; during stirred tank need heat and keep warm, close the steam pipe way, hot steam does not pass through the water tank, can not produce calorific loss promptly, consequently the utility model discloses a parallelly connected steam pipe way on the steam return pipe not only has realized steam waste heat recovery with the cooperation of electromagnetic type three way connection, has still realized the on-line switch of steam waste heat recovery and hot steam circulation heating.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.

FIG. 1 is a partial schematic view of a steam cycle system disclosed in the first embodiment;

FIG. 2 is a view showing an installation structure of a steam line disclosed in the first embodiment;

FIG. 3 is a partial structural view of a vapor line disclosed in the first embodiment;

fig. 4 is a partial schematic view of a steam cycle system disclosed in the second embodiment.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example one

The waste heat recovery device of the steam cycle system shown in fig. 1 comprises a water tank 10 and a plurality of steam pipelines 20. The water tank is provided with a water outlet I11 and a water inlet I12, and a temperature sensor and a liquid level meter are arranged in the water tank. A separate chamber 30 is provided in the middle of the tank, the chamber having a second inlet 31 and a second outlet 32 extending to the outside of the tank.

Referring to fig. 2, a plurality of steam pipes are fixed in the base 40 inside the chamber, and an upper connector and a lower connector of each steam pipe are respectively connected in parallel to a corresponding steam return pipe 60 in the steam cycle system through an electromagnetic type three-way joint 50. During the period that the stirring kettle does not need to be heated and kept warm, the steam pipeline is conducted by controlling the on-off of the three-way joint, so that the heat exchange of hot steam is carried out in the water tank, and the recovery of steam waste heat is realized; during the heating and heat preservation period of the stirring kettle, the steam pipeline is closed by controlling the on-off of the three-way joint, and hot steam does not pass through the water tank to realize hot steam circulation heating.

The plurality of heat dissipation fins 70 are arranged outside the base, so that the heat exchange efficiency is improved.

In the waste heat recovery stage, the steam is liquefied in the steam pipeline, so the present embodiment is provided with a drainage tube 80 communicated to the outside of the water tank at the bottom of the part of each steam pipeline located in the cavity.
