Description
Technical field
The utility model belongs to the gasifier device of the part device of petrochemical equipment, particularly a kind of fixed tube sheet warm water circulation type gasification device.
Background technology
Existing shell and tube warm water cycle gasification device adopts U type tubular construction and sleeve structure more.Operating experience for many years shows that these two kinds of structures all exist many inborn shortcomings, and 1. when needing quantity of circulating water less, when heat exchange area was big, the easy superelevation of equipment made troubles for transportation and operation.Resistance of medium is higher in the equipment, and influence gasification gas normally uses.2. when amount of vaporization is big, need a large amount of heat-exchanging tube bundles, having a spot of not condensing gas during hot water circuit can't discharge, thereby makes the hot water skewness that enters heat exchanger tube, causes heat exchange area to make full use of.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of fixed tube sheet warm water circulation type gasification device is provided.
The technical solution of the utility model is:
A kind of fixed tube sheet warm water circulation type gasification device is characterized in that: the below of cylindrical shell connects lower tube box, and the top of cylindrical shell connects end socket; Axial a plurality of deflection plates of arranged radially from bottom to up in the cylindrical shell are fixed by distance sink tube between the deflection plate; Barrel space is divided into many S shape passage; Cylindrical shell is suitable for reading the upper perforated plate flange of holding concurrently, the cylindrical shell end opening has the lower perforated plate flange of holding concurrently, hold concurrently flange and lower perforated plate of upper perforated plate held concurrently to have between the flange and is communicated with in the lower tube box communicating pipe in space in the space and end socket, and there is the liquid material import cylinder lateral wall below, and there is the gaseous state material outlet cylinder lateral wall top; Vertical demarcation strip is arranged in the lower tube box, in the demarcation strip both sides recirculated water inlet and circulating water outlet are arranged respectively on the lower tube box, the recirculated water discharging hole is arranged at the lower tube box bottom; There is not condensing gas discharge outlet on the end socket top.
Cylinder lateral wall has upper and lower liquid level gauge mouth, connects the liquid level gauge pipe between the upper and lower liquid level gauge mouth.
Material side amounts of pressurized gaseous meter mouth and material side gaseous state outlet temperature meter mouth are arranged on the cylinder lateral wall.
The lower tube box side has circulating water temperature meter mouth and recirculated water head pressure gage mouth.
Have in the middle of the distance sink tube and connect the pull bar of distance sink tube up and down.
There is skirt the border under the lower tube box.
The utility model structural advantages is:
1. simple in structure; In identical diameter of the housing, comb is maximum, and is compact; In the shell-side that deflection plate is arranged flows, E bypass minimum.2. solved the not condensing gas discharging in a water route difficult problem, the heat exchanger top is provided with automatically and manual exhaust valve.Can discharge not condensing gas in the water route, make unimpeded that warm water circulates in gasifier, guaranteed that distribution of water temperature is even, gasification is more all even fully to make gasifier outlet temperature and amount of vaporization more guaranteed thereby make, and 3. the gasifier water route can be designed to arbitrary even number number of passes, thereby improve water side heat transfer coefficient, reduced the requirement of equipment, thereby reduced per hour water consumption, using water wisely the water yield.4 because tube sheet is supported mutually by heat exchanger tube, compares with other shell-and-tube heat exchangers, and tube sheet is the thinnest, and cost is low.5. solved the restriction owing to the water route of U type and sleeve pipe, single device amount of vaporization difficulty is done a big difficult problem.
