Heat storage combustion device convenient to install and maintain

Abstract

The invention discloses a heat storage combustion device convenient to install and maintain. The device comprises a combustor, a communicating pipeline and a heat storage box; one end of the communicating pipeline communicates with the combustor, and the other end of the communicating pipeline communicates with the heat storage box; a lap of support net support profile steel is arranged on the inner wall of the heat storage box; a support net is placed on the support net support profile steel; the support net includes a lower-layer bracket and upper-layer round steel; the upper-layer round steel is arranged and welded as a grid structure; the lower-layer bracket is provided with multiple limiting grooves; all the limiting grooves have gaps; the round steel is limited in the limiting grooves; and the round steel is welded with the lower-layer bracket. The support net structure used by the heat storage combustion device convenient to install and maintain not only can satisfy the support strength demand of a heat storage ball, but also effectively reduces the welding structure to preferably prevent damage of the support net by high-temperature formation; and meanwhile, the round steel is fixed in the limiting grooves to guarantee no fall of the heat storage ball due to larger gaps formed by deformation or dislocation.

Description

technical field [0001] The invention relates to a regenerative combustion device, in particular to a regenerative combustion device which is easy to install and maintain. Background technique [0002] Regenerative combustion technology is one of the energy-saving combustion technologies with the best energy-saving effect in the world at present. Its principle is to use paired burners with regenerative bodies for organizational combustion. The heat storage tank can be installed above or below the burner, and connected with the burner through a communication pipeline. The connection between the communication pipeline and the burner, and the connection between the communication pipeline and the heat storage box are used in conjunction with bolts and flanges. After high temperature, it is easy to deform, and it will be difficult to assemble during maintenance or replacement. There is also the same problem in the switch of each function door on the heat storage tank. In additio...

AI Technical Summary

Problems solved by technology

The connection between the communication pipeline and the burner, and the connection between the communication pipeline and the heat storage box are used in conjunction with bolts and flanges. After high temperature, it is easy to deform, and it will be difficult to assemble during maintenance or replacement. The same problem also exists in the switch of each function door on the heat storage tank

In addition, the heat storage ball support net is a metal mesh structure arranged in the heat storage tank to support the heat storage ball. If the net structure is unreasonable or the strength is not enough, it will inevitably cause deformation or even damage during the continuous alternation of cold and heat, resulting in the failure of the device to work normally
