Description

Double-stage cooling cylinder for flue gas online monitoring system

Technical Field

The utility model relates to the technical field of environmental monitoring, in particular to a two-stage cooling cylinder for a flue gas online monitoring system.

Background

Along with the strong development of industrialization, the pollution condition in cities is more and more serious, and substances harmful to human bodies such as sulfur dioxide, carbon monoxide, smoke dust and the like in the atmosphere are more and more, so that the control of the smoke emission of factories and enterprises is very important. At present, the smoke emission of factories needs to strictly execute the national standard, if standardized monitoring management is not performed, the phenomena of theft emission and artificial counterfeiting can occur, and the emission which does not reach the standard can seriously pollute the environment, so that the smoke emission needs to be strictly monitored through a smoke monitoring system. The reliability, accuracy and stability of the flue gas on-line monitoring system are particularly important, because the water in the flue gas can influence the accuracy of the measurement data of the flue gas on-line monitoring system, and the water in the flue gas needs to be removed through a condenser of the flue gas on-line monitoring system. The condenser of the flue gas on-line monitoring system consists of a refrigeration compressor, a cooling pipeline, a cooling cylinder, a cold cavity, a peristaltic pump and a drainage pipeline, and the working flow of the condenser is as follows: firstly, the refrigerating compressor works to generate refrigerating gas, the refrigerating gas is transmitted to the cooling cylinder through the cooling pipeline, so that the temperature of the cooling cylinder is very low, a cold cavity is arranged on the cooling cylinder, the cooling cylinder transmits the low temperature to the cold cavity, the cold cavity has the effect of improving the dewatering effect, and the cooling cylinder is made of glass, and is internally provided with a threaded pipeline with silicone oil and a spiral glass material. The flue gas that flue gas on-line monitoring system gathered gets into the cold intracavity of condenser after the preliminary treatment, gets rid of the water in the flue gas through cold intracavity inner structure, and after cold intracavity water is out, discharges it through peristaltic pump. The cooling cylinder is an important part in the condenser, influences the dewatering effect of the condenser, and ensures that the dewatering effect of the cold cavity in the cooling cylinder is the most important factor for determining the good and bad use of the condenser. Two factors which affect the dewatering effect of the cold cavity are the structure inside the cold cavity and the temperature transferred to the cold cavity. For flue gas dehydration, the optimal temperature is controlled to be 4 ℃, so that the stable temperature control to be 4 ℃ is particularly important. In the case of a uniform internal structure of the cooling chamber, the temperature control capability of the cooling cylinder outside the cooling chamber is very important. The temperature control mode of the cooling cylinder is that the cooling pipeline transmits low temperature to the cooling cylinder, but the temperature needs to be controlled to be 4 ℃, so the cooling cylinder needs to be heated and kept at a constant temperature of about 4 ℃ to balance the temperature. However, in recent years, the actual working of the condenser of the flue gas online monitoring system is found to be unstable in working state, and the dehydration efficiency is low, because the conventionally manufactured single-cylinder cooling cylinder is poor in temperature control capability and low in efficiency, and the conventional single-cylinder cooling cylinder is not suitable for the requirement of gradually improving the current emission index. The two-stage cooling cylinder is of an elliptic cylinder structure, an approximately spiral thread line is processed on the outer wall of the elliptic cylinder, the thread line has a certain depth and a certain width, and in order to facilitate the condensing pipeline to be wound into the double-stage cooling cylinder, the double-stage cooling cylinder is difficult to process, a five-axis processing center is required to process, the processing cost is high, and each part reaches more than thousand yuan; or the die casting die is adopted for manufacturing, and the die opening cost is very high; the condensing tube is wound on the surface of the cooling cylinder, heat is transferred to the condensing cylinder through the outer wall of the condensing tube, energy is wasted, and the phenomenon of uneven heat transfer due to the fact that artificial winding is not strict in the winding process can occur, so that the condensing effect is affected; in addition, the conventional temperature control mode is to wrap a silica gel heating plate outside a cooling cylinder, and then wrap the whole body by using heat preservation cotton, so that the phenomenon that the heating plate and the heat preservation cotton are at the cold end of a joint and are heated unevenly can occur.
