Embodiment 1

[0043] Example 1, such as Figure 1-4 As shown, when the temperature in the warehouse body 1 is not up to the standard through the temperature monitor 31, the fan 32 and the annular electric heating wire 34 can be intelligently controlled to start, and the heating of the annular electric heating wire 34 is used to promote the heat to be concentrated in the annular cavity 33. The start of the blower fan 32 can form a guide wind to spray the heated heat evenly from the through hole 35, and then effectively and quickly heat the warehouse body 1, so as to promote the normal maintenance of the smoke dust collection heat of the warehouse body 1, so as to prevent The dust is bonded into agglomerates under the influence of large temperature difference fluctuations, which increases the active heating effect of the device.

Embodiment 2

[0044] Example 2, such as Figure 6-7 As shown, when the water pump 47 is started to pump the water in the water tank 46 into the diversion pipe 45 for waste heat utilization, the water level sensor can sense the water volume in the water tank 46, and when the water volume forms hot steam loss under the waste heat utilization structure , just can automatically fill into the water tank 46 by the water supply pipe, forming the recycling of the preheating and combustion-supporting system, so that the water liquid in the water tank 46 dries up completely, increasing the intelligent control effect of the device.

[0045] Working principle: when the device is in use, high-temperature flue gas can be introduced into the bin body 1, during which the pulse dust removal system 5 and the flue gas dust collection mechanism 2 are respectively activated through the console 6, and when the pulse dust removal system 5 is started, the bin body 1 The dust-removing filter element 23 inside carri...

Abstract

The invention discloses a zinc volatilization kiln flue gas high-temperature dust collection and waste heat utilization device, which comprises a bin body, a flue gas dust collection mechanism, a heating temperature control system, a heat conduction gas injection mechanism, a pulse dust removal system and a console, wherein the flue gas dust collection mechanism comprises a mounting frame, a guide dust discharge system, dust removal filter cores and a flue gas discharge pipeline. According to the invention, through mutual cooperation of the flue gas dust collection mechanism and the pulse dust removal system, high-temperature flue gas entering the bin body can be rapidly separated and subjected to dust collection; and during the period, dust particles separated by the three sets of dust removal filter cores can be promoted to fall into the corresponding three sets of conical guide grooves through structural cooperation of the guide dust discharge system, along with centrifugal rotation of the conical guide grooves, and falling dust can be guided and discharged to be prevented from being attached to the inner wall of the conical cavity while the spiral guide rod is driven to rotate under rotation of the conical guide groove to guide and disturb the flue gas entering the bin body, so that the fluidity of the flue gas is improved, and the dust collection efficiency of the flue gas is improved.

Description

technical field [0001] The invention relates to the technical field of zinc volatilization kilns, in particular to a high-temperature dust collection and waste heat utilization device for flue gas of a zinc volatilization kiln. Background technique [0002] During the zinc leaching slag volatilization kiln process, the flue gas is generally subjected to dust collection treatment. Through the implementation of the flue gas dust collection process in the zinc leaching slag volatilization kiln treatment process, not only the separation of zinc elements in solid waste is effectively realized, but secondary zinc oxide is formed. The product and kiln slag are returned to sintering for comprehensive utilization, and the waste heat generated in this process is effectively recovered to generate saturated steam for use. [0003] When the current volatilization kiln collects dust at high temperature, because the temperature in the flue gas is relatively good, direct treatment and disch...
