Sulfur-related equipment cleaning device with mixed heat source

Abstract

The invention belongs to the field of chemical equipment cleaning, and relates to cleaning of sulfur-related equipment in a gas field, in particular to a sulfur-related equipment cleaning device witha mixed heat source. The sulfur-related equipment cleaning device comprises a power distribution system, and further comprises a heating system, a heat exchange system, a cleaning system, a flushing system, a descaling system and a purging system, wherein the heating system comprises a heating furnace skid and a mixed heating device, the heat exchange system comprises a hot water heat exchanger and a medicament tank skid, the cleaning system comprises a circulating supercharging device and a clear water tank skid, and the descaling system is a jet flow sand-mud removal skid; the purging systemcomprises an air compressor, an air tank and an air pipeline; and the mixed heating device comprises a manifold arranged on the upper portion of the heating furnace skid, solar pipe sets are arrangedon the two sides of the manifold, the heating furnace skid is connected with an inlet of the manifold through a pipeline, and an outlet of the manifold is connected with a circulating pump. The sulfur-related equipment cleaning device is suitable for cleaning a gas transmission pipeline, can be used for deeply cleaning sulfur-related equipment in the gas transmission pipeline, has an obvious useeffect, and has obtained a huge commercial application value.

Description

technical field [0001] The invention belongs to the field of chemical equipment cleaning, and relates to the cleaning of sulfur-related equipment in gas fields, in particular to a cleaning device for sulfur-related equipment with mixed heat sources. Background technique [0002] Puguang Gas Field is the first large-scale integrated high-sulfur gas field developed in China. With the continuous development of the gas field, sulfur deposits in the process equipment and pipelines of the surface engineering gas-gathering station are serious and dirt deposits exist in important equipment. The high-sulfur gas field is in production During the process, since the pressure and temperature of the natural gas gradually decrease from the bottom of the well to the wellhead and then to the gathering and transportation system, elemental sulfur will be precipitated, and the fracturing fluid returned from the bottom of the well will Residual substances, etc. are continuously attached to the i...

Problems solved by technology

[0006] (1) Manual cleaning of oil tanks requires entry into a confined space for operations. Crude oil from the ground has complex components, natural gas contains various alkanes, and some blocks contain H 2 S, CO and other toxic gases, lack of oxygen in the oil tank, there is a risk of poisoning and suffocation;

[0007] (2) During summer cleaning, when personnel enter the oil tank, under the sun, the temperature inside the tank is much higher than the external temperature, and there is a risk of heat stroke;

[0008] (3) When working in a confined space, non-sparking explosion-proof tools must be used; otherwise, the shovel will hit the tank wall and sparks will be generated; oily sand contains combustible gas, and it is very easy to explode after collision;

[0009] (4) The oil well is shut down for inspection and maintenance, and the economic benefits are affected during the shutdown period;

[0010] (5) If fuel is used as fuel to supply fuel to the heating furnace, the equipment used for heating oil, the natural gas in the fuel supply pipeline contains oil (associated gas), and the associated gas has not been purified and contains crude oil particles; after passing through the burner, the atomization does not Complete, incomplete combustion. After the crude oil suspension particles in the fuel are burned, black smoke will emerge from the chimney, affecting the atmospheric environment and failing to meet environmental protection requirements;

[0011] (6) Black smoke will be emitted for a long time, carbon deposits will be generated in the heating cylinder and other parts, and the heat exchange parts of the heating cylinder and pyrotechnic tube will be blocked; the high-temperature smoke cannot be removed in time, and it is easy to explode at the burner part
