Problems solved by technology

Due to the compressive strength of the graphite cylinder, the connection strength between the cylinder and various pipes and components is limited, the output is low-pressure steam, and the utilization rate of heat energy is low. It is necessary to establish a separate user steam network, which has great limitations.
The other type is the steel in...

Embodiment Construction

[0012] As shown in the accompanying drawings, the present invention relates to a combined hydrogen chloride synthesis furnace capable of producing high-pressure steam by-product, which includes a synthesis furnace for synthesizing hydrogen chloride gas and a cooler 4 for cooling high-temperature hydrogen chloride gas on its upper part.

[0013] The synthesis furnace is divided into upper section 1, middle section 2 and lower section 3, all of which are composed of a graphite cylinder a and a steel casing b set outside the cylinder. The internal graphite cylinders 1a, 2a, and 3a of the upper, middle, and lower sections are bonded and conducted with graphite-filled phenolic adhesive to form an inner cavity for preparing hydrogen chloride gas; the outer steel shells 1b, 2b , 3b are connected by flanges 14, 15, and the three and the graphite cylinder 1a, 2a, 3a form three mutually non-conductive interlayers.

[0014] The bottom end of the lower section 3 of the synthesis furnace i...

Abstract

The invention relates to a combined type hydrogen chloride synthetic furnace of by-product high-pressure steam, comprising a synthetic furnace and a cooler at the top part of the synthetic furnace; the synthetic furnace is composed of an upper section graphite barrel, a middle section graphite barrel and a lower section graphite barrel and a steel shell sheathed outside the barrel, the lower section steel shell is communicated with the upper section steel shell by a pipeline to form a cooling water circulating channel, and an independent cooling water circulating channel is arranged on the middle section steel shell. The middle section of the synthetic furnace is a high-temperature section and adopts the high pressure resistant graphite barrel, the steel shell and the independent cooling water circulating channel, and the shell is separated from the shells at two ends, the middle section graphite barrel is not connected with various pipelines or parts, the problem of pressure resistance of the whole middle section is solved, so as to lead hot water flowing out from the middle section to generate high-pressure steam through a flash drum for direct use by users or other steam network without building an independent steam network.

Description

technical field [0001] The invention relates to a synthesis furnace, in particular to a combined hydrogen chloride synthesis furnace which produces high-pressure steam by-product. Background technique [0002] The hydrogen chloride synthesis furnace is used to burn chlorine and hydrogen to produce hydrogen chloride gas. When chlorine gas and hydrogen are combusted, a large amount of heat of reaction is released, and the temperature in the central area of ​​the flame reaches above 2500°C, and the temperature of the generated hydrogen chloride gas is above 2000°C, that is, about 605Kcal of heat is released for every kilogram of gaseous hydrogen chloride synthesized, which is quite considerable for utilization. [0003] At present, there are two types of hydrogen chloride synthesis furnaces on the market. The first type is a widely used all-graphite synthesis furnace, which is composed of a graphite inner cylinder and a steel outer wall. During the reaction, cooling water is pa...
