Embodiment Construction
[0022] This part will further describe and illustrate the present invention by specific embodiments:
[0023] Such as figure 1 As shown, a device for realizing hydrothermal carbonization reaction includes a reactor 1, which is connected to a pulper 2 through a feed pipe 8, and the feed pipe 8 transports pretreated biomass to the reactor 1. The hopper 6 transports the biomass to the pulper 2 in preparation for the reaction feed. Between the hopper 6 and the pulper 2, there is a conveying unit and a pollutant separation device, which may be a metal separator, and the pollutants are separated and the conveying unit provides biomass for the pulper 2. In all reaction tanks 1 connected to the pulper 2, the feed required for the reaction operation is supplied via a feed pipe 8 connected to the pulper 2 and stored there, in which the heated biomass Immediately replaced by fresh, cold biomass from hopper 6. The steam generator 4 is connected to the pulper 2 through the steam pipe 11...

The hydrothermal carbonization reaction is carried out in the reactor, which is in a high temperature, high pressure and steam environment. Since the charging process of the reactor is carried out in batches, the biomass needs to pass through the pulper in advance and be pre-heated to occur in the reactor. After the reaction, the slurry output from the reactor needs to be cooled in a surge tank. The present invention provides a new hydrothermal carbonization reaction device, so that the cooling of the slurry is connected with the preheating of the biomass. Specifically, heat exchangers are arranged in the pulper and the buffer tank, and they are connected to each other to form a heat cycle. The system enables the slurry to be cooled to provide the heat released by cooling to the biomass that needs to be heated in advance, so that the energy loss in the system can be significantly reduced, and the energy can be reused.
Description
technical field [0001] The invention relates to a device for carrying out hydrothermal carbonization reaction, in particular to a hydrothermal carbonization reaction device which can reduce system energy loss and enable energy to be reused. Background technique [0002] The existing hydrothermal carbonization reaction device usually includes a reactor, which absorbs steam through a steam generator, and is connected with a mixing tank through a feed pipe to charge biomass, and is connected with a buffer tank, which will The slurry formed from hot steam and biomass in the reaction tank is discharged into the buffer tank. For example, in the patent DE 10 2011 001 108 A1, such a hydrothermal carbonization reaction device is provided: the reaction is carried out in a reactor, and the reactor is fed through a mixing tank or a preheating tank, and the mixing tank or the preheating tank Connected to the reactor via a fixed fuel pump. After the biomass is pretreated, the pressure a...
