Small constant pressure coking device

Abstract

The invention discloses a small constant-pressure coking device, which relates to the technical field of laboratory coking, and specifically includes a base, a waste gas treatment box and a coking tank installed on the base, wherein the two ends of the top of the coking tank are respectively vertically installed with a The bottom end of the support rod is fixedly connected, and the top end of the support rod is fixedly connected with the two ends of the bottom surface of the constant pressure tank respectively, and the pressure inside the coking tank is controlled through the constant pressure tank. One end extends into the inner bottom of the constant pressure tank, and the other end of the outlet pipe extends into the bottom of the waste gas treatment box installed on the base. Compared with the prior art, the present invention has the beneficial effects that the constant pressure tank realizes the constant control of the air pressure of the coking device, and the air pressure of the coking device is easy to adjust, thereby improving the practicability of the coking device.

Description

technical field [0001] The invention relates to the technical field of laboratory coking, in particular to a small constant pressure coking device. Background technique [0002] my country is a big country in coke production, consumption and export. Since the early 1990s, the output and export volume have ranked first in the world. The largest consumer of coke is the steel industry, accounting for more than 80%, mainly used for blast furnace ironmaking. In the blast furnace ironmaking process, coke is mainly used as heat source, reducing agent, carburizing agent and loose skeleton. With the enlargement of blast furnaces and the development and application of technologies such as oxygen-enriched pulverized coal injection (the domestic maximum coal injection volume can reach 261kg / t pig iron), the requirements for the quality of coke produced by blast furnaces, especially the thermal performance of coke, are getting higher and higher. Due to the increasingly tight supply of hig...

Problems solved by technology

[0004] In the patent No. CN105861002A, a small constant pressure coking device and constant pressure coking method are disclosed, compared to the automatic bottom-mounted experimental coke oven disclosed in the Chinese patent No. CN203754635U, and the patent No. CN202881174U A 40Kg test coke oven that can measure the coking expansion pressure disclosed in the Chinese patent, although it has the effect of constant pressure coking, but to achieve this effect, equipment such as hydraulic pumps, buffer cylinders, and oil pressure regulators are required. This is undoubtedly Increase the cost of the enterprise, if the constant pressure effect can be achieved through some simple structures, it will effectively solve the above problems
