Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery devices, in particular to a waste heat recovery device. Background Art

[0002] Water glass is commonly known as sodium silicate. Water glass is a water-soluble silicate, and its aqueous solution is commonly known as water glass. Water glass is a mineral adhesive. In the chemical production process, water glass dissolution is a common process link. When producing water glass, a large amount of heat energy is required to maintain an appropriate dissolution temperature. In traditional processes, this heat energy is usually provided by the boiler room and directly transported to the production workshop through pipelines. However, this method of heat energy transmission has obvious limitations, especially when the production workshop fails to continue production due to various factors;

[0003] The existing waste heat recovery device for water glass dissolution mainly relies on the immediate utilization of heat energy in the production workshop. When the production workshop is operating normally, part of the heat energy can be effectively recovered. However, when the production in the production workshop stops, the heat energy cannot be effectively stored and reused, resulting in a huge waste of energy, thereby reducing the utilization rate of energy. Therefore, a waste heat recovery device is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the shortcoming of low heat utilization rate in the prior art and proposes a waste heat recovery device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A waste heat recovery device comprises a heat accumulator, the heat accumulator is connected to a circulation pipeline group, and the circulation pipeline group is connected to an original pipeline group.

[0007] The circulation pipeline group includes a heat inlet pipe and a heat outlet pipe, the heat inlet pipe and the heat outlet pipe penetrate the top of the heat accumulator, and one end of the heat inlet pipe and the heat outlet pipe are connected to the conduit together.

[0008] A water supply tank is connected to a delivery pipeline group, and the delivery pipeline group is connected to the water inlet of the heat accumulator.

[0009] The delivery pipeline group includes a main delivery pipe, both ends of which are connected to the heat accumulator and the water supply tank respectively, a ball valve is arranged on the main delivery pipe, and an auxiliary delivery pipe is connected to the main delivery pipe.

[0010] Preferably, the original pipeline group includes a connecting joint, which is connected to one end of the conduit, and the two joints of the connecting joint are respectively connected to the slave pipe and the master pipe.

[0011] Preferably, a plurality of support seats are provided at the bottom of the heat accumulator.

[0012] Preferably, valves are provided on the heat inlet pipe, the heat outlet pipe, the main pipe and the auxiliary transport pipe.

[0013] Preferably, the auxiliary delivery pipe is "U"-shaped, and the water supply tank is a vertical water supply tank.

[0014] Preferably, the heat outlet pipe and the main transport pipe are both connected to the heat supply port of the heat accumulator, and the heat inlet pipe is connected to the heat inlet port of the heat accumulator.

[0015] The utility model has the following beneficial effects:

[0016] 1. With the cooperation of the heat accumulator and the water supply tank, the heat generated in the boiler room can be stored in the heat accumulator when the production workshop is not working, which effectively solves the problem of heat waste when the production workshop is not in production, avoids unnecessary heat loss, and passes the heat into the water supply tank to heat its steam, thereby improving the reuse efficiency of heat energy, which not only reduces the energy consumption in the production process, but also improves the overall utilization efficiency of heat energy, making a positive contribution to the company's energy conservation and emission reduction work, thereby reducing the generation of pollutants and improving environmental quality;

[0017] 2. Under the action of the circulation pipe group and the delivery pipe group, the heat generated by the boiler room enters the heat accumulator from the heat inlet pipe through the conduit. When the production workshop needs heating, the conduit is opened so that the heat can be re-input from the heat outlet pipe into the production workshop, thereby increasing the effectiveness of energy. At the same time, when part of the main delivery pipe needs maintenance, the ball valve can be closed to allow the heat to be transported to the water supply tank through the auxiliary delivery pipe, thereby improving the practicality of the device.
