Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0032] The application provides a double-chamber kiln, which includes a kiln shell and a plurality of spray guns, the kiln shell has a kiln chamber, and the spray guns are fixed on the kiln shell. The external gas and combustion-supporting air enter the kiln through the spray gun for combustion.

[0033] A double-chamber kiln has two kiln chambers, and multiple spray guns are installed on the kiln shell of each kiln chamber. Optionally, 20 to 40 spray guns are installed on the kiln shell of each kiln chamber, which is not limited in this application, and the number of spray guns can be adjusted according to the size of the kiln chamber and the flow rate of the spray guns.

Abstract

The invention provides spray guns and a double-kiln-chamber kiln, and belongs to the technical field of double-kiln-chamber kilns. Each spray gun comprises a spray gun box, a spray gun pipe and a compensating pipe; the spray gun boxes are provided with cover plates which are provided with mounting holes; the spray gun pipes are provided with first ends and second ends, the first ends are insertedinto the mounting holes, sealing filler seats filled with sealing filler are arranged in gaps between the outer walls of the first ends and the cover plates, and the second ends are located outside the spray gun boxes; the compensation pipes are sleeved outside the second ends, gaps are reserved between the compensation pipes and the outer walls of the second ends, and sealing cavities are formedamong the outer walls of the second ends, the inner walls of the compensation pipes and the sealing filler seats; and the double-kiln-chamber kiln comprises a kiln shell and the plurality of spray guns, kiln chambers are arranged in the kiln shell, and the spray gun boxes are arranged on the inner wall of the kiln shell and are in communication with the kiln chambers. The spray guns are provided with the compensation pipes, and air leakage between the spray gun pipes and the spray gun boxes can be avoided.

Description

technical field [0001] The present application relates to the technical field of double-chamber kiln, in particular, to a spray gun and a double-chamber kiln. Background technique [0002] The double-chamber kiln is an industrial kiln with the characteristics of heat storage and parallel flow, and the fuel is mainly gas, solid and liquid. The double-chamber kiln consists of two kiln chambers, each of which is usually equipped with 33 spray guns, and a kiln has a total of 66 spray guns. The function of the spray guns of the double-chamber kiln is to spray gas into the kiln during combustion. , the coal gas is mixed with the combustion-supporting air pressed in from the top and then burned to generate the heat required for calcining the limestone to decompose the limestone. The double-chamber kiln is a positive pressure operation, and the kiln pressure is about 30kPa, so the sealing performance of the spray gun is required to be better. [0003] The spray gun of the double-c...
